本发明涉及通信传输领域，尤其涉及一种业务数据传输方法、装置和系统。The present invention relates to the field of communication transmission, in particular to a service data transmission method, device and system.
背景技术Background technique
业务数据的传输与使用在现在的生活中随处可见，如视频监控业务。通过视频监控可以获取相关路段、住宅小区、学校、银行、车站以及医院等公众场合的实时视频信息，为把握道路信息、记录往来人员情况以及控制人流及车流量等方面提供了有力的保障。在早期，对视频监控的传输普遍使用有线传输的方法，该方法是提前规划好需要监控的物理节点，然后进行建设，最终有益效果是对固定的监控点实现高质量的实时监控视频。随着无线通信网络的大规模普及，又由于其传输速率已经能够基本满足视频无线传输的条件，因此无线通信网络也已经应用于监控视频的传输。The transmission and use of business data can be seen everywhere in today's life, such as video surveillance services. Real-time video information of public places such as relevant road sections, residential quarters, schools, banks, stations, and hospitals can be obtained through video surveillance, which provides a strong guarantee for grasping road information, recording the situation of people coming and going, and controlling the flow of people and vehicles. In the early days, the method of wired transmission was commonly used for the transmission of video surveillance. This method is to plan the physical nodes to be monitored in advance, and then carry out construction. The final beneficial effect is to achieve high-quality real-time surveillance video for fixed monitoring points. With the large-scale popularization of wireless communication network, and because its transmission rate can basically meet the conditions of wireless video transmission, wireless communication network has also been applied to the transmission of surveillance video.
现有技术中，利用单片机和通用分组无线服务技术(GPRS，General PacketRadio Service)通信模块的性能优势,在现有的有线摄像头基础上加上GPRS通信模块，实现了视频的无线传输。当无线网络出现故障时，将导致视频传输中断，并且无线网络覆盖范围有限，在无线网络信号的盲区无法利用无线方式对视频进行传输，从而影响了实时传输中对视频内容的分析与利用。In the prior art, the wireless transmission of video is realized by utilizing the performance advantages of a single-chip microcomputer and a General Packet Radio Service (GPRS, General Packet Radio Service) communication module, and adding a GPRS communication module on the basis of an existing wired camera. When the wireless network fails, the video transmission will be interrupted, and the coverage of the wireless network is limited. In the blind area of the wireless network signal, the video cannot be transmitted wirelessly, which affects the analysis and utilization of video content in real-time transmission.

It is understandable that those skilled in the art can apply the technical solutions in the subsequent embodiments to other In the transmission of service data of different types, details are not described in this embodiment of the present invention.
参见图1，其示出了本发明实施例提供的一种应用场景，该场景中可以包括：数据采集装置、中央监控站和监控客户端。Referring to FIG. 1 , it shows an application scenario provided by an embodiment of the present invention, which may include: a data collection device, a central monitoring station, and a monitoring client.

实施例一Embodiment one
本发明实施例提供一种业务数据传输方法，应用于数据采集装置一侧，如图2所示，所述方法可以包括：An embodiment of the present invention provides a service data transmission method, which is applied to the side of the data acquisition device. As shown in FIG. 2, the method may include:
S101、数据采集装置获取至少一个数据流。S101. The data acquisition device acquires at least one data stream.
数据采集装置在一个时间段内可以获取到一个或多个不同大小的数据流。例如，在视频监控业务中，数据采集装置获取到的数据流可以为信令、语音、标清视频、高清视频等。The data acquisition device can acquire one or more data streams of different sizes within a period of time. For example, in a video surveillance service, the data streams acquired by the data acquisition device may be signaling, voice, standard definition video, high definition video, and the like.
可选地，当数据采集装置在一个时间段内获取到不同大小的数据流时，参见图3，本方法还可以包括：Optionally, when the data acquisition device acquires data streams of different sizes within a period of time, referring to FIG. 3, the method may further include:
S1011、根据数据流的数据量确定各数据流的优先级别。S1011. Determine the priority level of each data flow according to the data volume of the data flow.
不同数据流的数据包大小不一，对各个数据流按照其数据包的大小进行排序。例如，在视频监控业务中，按数据流的数据包大小从小到大排列，则依次为信令、语音、标清视频、高清视频。数据流的数据包越小，则数据流优先级越高，反之，数据流的数据包越大，则数据流优先级越低。由此可见，在例举的数据流中，数据流优先级从高到低排列依次为信令、语音、标清视频、高清视频。Data packets of different data streams have different sizes, and each data stream is sorted according to the size of its data packets. For example, in the video surveillance service, according to the packet size of the data flow, the order is signaling, voice, standard-definition video, and high-definition video. The smaller the data packet of the data flow, the higher the priority of the data flow, conversely, the larger the data packet of the data flow, the lower the priority of the data flow. It can be seen that, in the example data streams, the priorities of the data streams are signaling, voice, standard-definition video, and high-definition video in order from high to low.
S1012、按照各数据流的优先级别将不同数据流对应放入不同的数据流队列。S1012. Correspondingly put different data flows into different data flow queues according to the priority level of each data flow.
具体地，将优先级别最高的数据流放入队列1，将优先级别次之的数据流放入队列2，按照该方式将所有的数据流依次放入不同的队列中。这里，以语音、标清视频、高清视频为例进行说明。上述三种数据流优先级从高到低排列依次为语音、标清视频、高清视频，因此，将语音放入队列1，将标清视频放入队列2，将高清视频放入队列3。Specifically, the data flow with the highest priority is put into queue 1, the data flow with the second priority is put into queue 2, and all data flows are put into different queues sequentially in this manner. Here, voice, standard-definition video, and high-definition video are taken as examples for illustration. The priorities of the above three data streams are voice, standard definition video, and high definition video from high to low. Therefore, put voice into queue 1, put standard definition video into queue 2, and put high definition video into queue 3.
S102、数据采集装置根据自身的各传输路径对应的指标参数和权重因子以及数据流的数据量确定各传输路径所对应的待传输数据量；S102. The data acquisition device determines the amount of data to be transmitted corresponding to each transmission path according to the index parameters and weight factors corresponding to each transmission path and the data volume of the data stream;
其中，所述数据采集装置至少包含两条传输路径。Wherein, the data collection device includes at least two transmission paths.
示例性地，参见图4，步骤S102具体可以包括：For example, referring to FIG. 4, step S102 may specifically include:
S1021、确定各传输路径的指标参数和权重因子。S1021. Determine index parameters and weight factors of each transmission path.
其中，各传输路径的指标参数为往返时延响应度和带宽可利用率。Among them, the index parameters of each transmission path are round-trip delay response and bandwidth availability.
优选地，各传输路径的往返时延响应度表示了各传输路径的网络状况，可由以下方法确定：Preferably, the round-trip delay response of each transmission path represents the network condition of each transmission path, which can be determined by the following method:
确定传输路径的往返时延T，往返时延T越小表示该传输路径网络状况越好。当传输路径的往返时延T增长速度过快，则可以判断该传输路径发生了拥塞。The round-trip delay T of the transmission path is determined, and the smaller the round-trip delay T is, the better the network condition of the transmission path is. When the round-trip delay T of the transmission path increases too fast, it can be judged that the transmission path is congested.
本实施例中视频监控业务的数据采集装置有两条传输路径对数据流进行传输，传输路径1为有线传输方式，传输路径2为无线传输方式。设R为往返时延响应度，该指标参数的值等于往返时延的倒数，即R＝1/T，往返时延响应度越大说明传输路径的网络状况越好。由上述方法可知，传输路径1的往返时延响应度表示为R1＝1/T1，传输路径2的往返时延响应度表示为R2＝1/T2。The data acquisition device for the video surveillance service in this embodiment has two transmission paths to transmit data streams, the transmission path 1 is a wired transmission mode, and the transmission path 2 is a wireless transmission mode. Let R be the round-trip delay response. The value of this index parameter is equal to the reciprocal of the round-trip delay, that is, R=1/T. The greater the round-trip delay response, the better the network condition of the transmission path. It can be seen from the above method that the round-trip delay responsivity of transmission path 1 is expressed as R1 =1/T1 , and the round-trip delay response of transmission path 2 is expressed as R2 =1/T2 .
优选地，各传输路径的带宽可利用率可由以下方法确定：Preferably, the bandwidth availability of each transmission path can be determined by the following method:
带宽可利用率表示传输路径的负荷情况，带宽可利用率越高，传输路径的网络负荷就越低，可承载更多的数据流传输。定义a％为传输路径1的端口带宽占用率，则传输路径1的带宽可利用率为1-a％。同理，定义b％为路径2的端口带宽占用率，则路径2的带宽可利用率为1-b％。其中，a％(或b％)为端口实际占用带宽除以端口配置带宽的比值，例如，端口实际传输占用的带宽统计为40Mbit/s,而端口配置的带宽为100Mbit/s，则占用的带宽率为40％，即a％＝40％，那么带宽可利用率为1-a％＝60％。The bandwidth availability indicates the load condition of the transmission path. The higher the bandwidth availability, the lower the network load of the transmission path, which can carry more data flow transmission. If a% is defined as the port bandwidth occupancy rate of the transmission path 1, then the bandwidth availability rate of the transmission path 1 is 1-a%. Similarly, if b% is defined as the port bandwidth occupancy rate of path 2, then the bandwidth availability rate of path 2 is 1-b%. Among them, a% (or b%) is the ratio of the actual bandwidth occupied by the port divided by the configured bandwidth of the port. For example, the actual bandwidth occupied by the port is 40Mbit/s, and the configured bandwidth of the port is 100Mbit/s. The ratio is 40%, that is, a%=40%, then the bandwidth availability ratio is 1−a%=60%.
在各传输路径往返时延响应度和带宽可利用率确定之后可以得到权重因子；优选地，权重因子可以由往返时延响应度的权重与带宽可利用率的权重共同组成，例如，权重因子总和为1。假定往返时延响应度占的权重为X％，则可利用带宽率占的权重为1-X％。The weight factor can be obtained after the round-trip delay responsiveness and bandwidth availability of each transmission path are determined; preferably, the weight factor can be composed of the weight of the round-trip delay responsiveness and the weight of the bandwidth availability, for example, the sum of the weight factors is 1. Assuming that the weight of the round-trip delay responsiveness is X%, the weight of the available bandwidth rate is 1-X%.
S1022、根据指标参数和权重因子以及数据流的数据量确定各传输路径的待传输数据量。S1022. Determine the amount of data to be transmitted for each transmission path according to the index parameter, the weight factor, and the data amount of the data flow.
用D代表一个时段内的数据总量，仍然以两条传输路径为例，根据指标参数和权重因子可得传输路径1分配的数据量D1，可以用公式(1)表示：Use D to represent the total amount of data in a period, still taking two transmission paths as an example, according to the index parameters and weight factors, the data volume D1 allocated by transmission path 1 can be obtained, which can be expressed by formula (1):
而传输路径2分配的数据量D2可以用公式(2)表示：And the amount of data D2 allocated by transmission path2 can be represented by formula (2):
需要说明的是，公式(1)中的R1/(R1+R2)表示传输路径1与两条传输路径的传输质量之比，公式(2)中的R2/(R1+R2)表示传输路径2与两条传输路径的传输质量之比。通过传输质量之比，在一定程度上限制了网络较差的路径上的数据发送量。It should be noted that R1 /(R1 +R2 ) in formula (1) represents the ratio of the transmission quality of transmission path 1 to the two transmission paths, and R2 /(R1 +R2 ) represents the ratio of the transmission quality of the transmission path 2 to the two transmission paths. Through the ratio of transmission quality, the amount of data sent on the poorer path of the network is limited to a certain extent.
公式(1)中的表示当前传输路径1与两条传输路径的带宽可利用率之比，公式(2)中表示当前传输路径2与两条传输路径的带宽可利用率之比。通过带宽可利用率之比，在一定程度上限制了网络高负荷的路径上的数据发送量。In the formula (1) Indicates the ratio of the bandwidth availability of the current transmission path 1 to the two transmission paths, in formula (2) Indicates the ratio of the bandwidth availability of the current transmission path 2 to the two transmission paths. Through the ratio of bandwidth availability, the amount of data sent on the path with high network load is limited to a certain extent.
优选的，采用权重因子往返时延响应度和带宽可利用率各占50％的权重可以优化的分配数据量，因此可得公式(3)和公式(4)：Preferably, the amount of allocated data can be optimized by using the weight factor that the round-trip delay responsiveness and the bandwidth availability rate each account for 50%, so formula (3) and formula (4) can be obtained:
在往返时延响应度和带宽可利用率权重占比各为50％的情况下，各传输路径自动分配到所需要承担的传输数据量，其优势是:两条传输路径所能发送的数据总量得到合理分配，有效地分配了2条传输路径数据发送量的比例，使网络按质量来均衡使用，取得了更高的传输效率。When the round-trip delay responsiveness and the weight ratio of bandwidth availability are 50%, each transmission path is automatically allocated to the amount of transmission data that needs to be borne. The advantage is that the total amount of data that can be sent by the two transmission paths The volume is allocated reasonably, and the ratio of the data transmission volume of the two transmission paths is effectively allocated, so that the network can be used in a balanced manner according to the quality, and higher transmission efficiency has been achieved.
S103、数据采集装置按照各传输路径对应的待传输数据量通过所述各传输路径将所述数据流传输至中央监控站。S103. The data acquisition device transmits the data stream to the central monitoring station through each transmission path according to the amount of data to be transmitted corresponding to each transmission path.
由于在视频监控业务实际的数据分配过程中，两条传输路径可能会出现其中一条传输路径满负荷或发生故障的情况，因此本实施例还包括：Since in the actual data distribution process of the video surveillance service, one of the two transmission paths may be fully loaded or fails, so this embodiment also includes:
参见图5，S103可以包括步骤S1031至S1033：Referring to FIG. 5, S103 may include steps S1031 to S1033:
S1031：根据各传输路径与中央监控站的反馈信息获取各传输路径的传输状态。S1031: Obtain the transmission status of each transmission path according to feedback information from each transmission path and the central monitoring station.
以视频监控业务的数据采集装置为例，两条传输路径会将自身的带宽可利用率和往返时延响应度反馈回数据采集装置，同时会接收中央监控站反馈的数据信号异常的信息。根据上述的反馈信息，数据采集装置可以获取两条传输路径的传输状态，所述传输状态包括可用与非可用两种情况。Taking the data acquisition device of the video surveillance business as an example, the two transmission paths will feed back their own bandwidth availability and round-trip delay responsiveness to the data acquisition device, and at the same time receive the abnormal information of the data signal fed back by the central monitoring station. According to the above feedback information, the data acquisition device can acquire the transmission status of the two transmission paths, and the transmission status includes two situations of availability and non-availability.
S1032、当有至少一个传输路径为非可用时，将数据流转入其他可用的传输路径发送到中央监控站。S1032. When at least one transmission path is unavailable, transfer the data flow to other available transmission paths and send it to the central monitoring station.
在具体实现过程中，步骤S1032可以包括：In a specific implementation process, step S1032 may include:
按所述数据流队列的顺序将数据流转入其他可用的传输路径；根据所述其他可用的传输路径所对应的待传输数据量将数据流按数据流队列顺序通过所述传输路径传输至中央监控站。According to the order of the data flow queue, the data flow is transferred to other available transmission paths; according to the amount of data to be transmitted corresponding to the other available transmission paths, the data flow is transmitted to the central monitoring through the transmission path in the order of the data flow queue stand.
当网络的端口满负荷时，带宽可利用率为0％，即1-a％＝0％，或者当网络出现物理中断时，该传输路径将会失效，并且会将传输路径失效的信息反馈回来。接收到该路径失效信息时，将判断该路径的往返时延响应度和带宽可利用率为0，不再分配数据到该失效路径传送。When the port of the network is fully loaded, the bandwidth utilization rate is 0%, that is, 1-a%=0%, or when the network is physically interrupted, the transmission path will fail, and the transmission path failure information will be fed back . When the path failure information is received, it will be judged that the round-trip delay response and bandwidth availability of the path are 0, and no data will be allocated to the failed path for transmission.
示例性的，本发明实施例中的视频监控业务传输路径1为光纤传输，当传输路径1的带宽占用率为100％或者路径1的物理光纤中断，即R1＝0，1-a％＝0，此时传输路径1分配的数据量为公式(5)：Exemplarily, the video surveillance service transmission path 1 in the embodiment of the present invention is optical fiber transmission, when the bandwidth occupancy rate of the transmission path 1 is 100% or the physical optical fiber of the path 1 is interrupted, that is, R1 =0, 1-a%= 0, at this time, the amount of data allocated by transmission path 1 is formula (5):
而此时传输路径2分配的数据量为公式(6)：At this time, the amount of data allocated by transmission path 2 is formula (6):
传输路径1将不再分配数据量，而传输路径2分配的数据量为D。也即是说，原本计划将在传输路径1发送的数据量，全部倒换到传输路径2中传送。对本实施例中的视频监控业务来说，整个倒换时间小于50ms，不会中断监控视频的传输，因此不会在倒换过程中造成监控视频的丢失。此时传输数据流需按照数据流队列的顺序进行传输，优先级越高的越先输出，优先级越低的越后输出。Transmission path 1 will no longer allocate data volume, while the data volume allocated to transmission path 2 is D. That is to say, all the data volume originally planned to be sent on the transmission path 1 is switched to the transmission path 2 for transmission. For the video monitoring service in this embodiment, the entire switching time is less than 50 ms, and the transmission of the monitoring video will not be interrupted, so the monitoring video will not be lost during the switching process. At this time, the transmission data flow needs to be transmitted according to the order of the data flow queue, the higher priority is output first, and the lower priority is output last.
具体地，在步骤S101中排列好的的数据流队列按照队列顺序将数据流输出到各传输路径，即队列1最先输出，队列2随后输出，队列3最后输出。按照上述队列编号顺序，先将队列1的语音输出到传输路径2，待队列1的语音输出完毕后，再将队列2的标清视频输出到传输路径2，待队列2的标清视频输出完毕后，最后将队列3的高清视频输出到传输路径2。Specifically, the data stream queues arranged in step S101 output the data streams to each transmission path according to the queue order, that is, queue 1 outputs first, queue 2 outputs next, and queue 3 outputs last. According to the order of queue numbers above, first output the voice of queue 1 to transmission path 2, and then output the standard definition video of queue 2 to transmission path 2 after the voice output of queue 1 is completed, and then output the standard definition video of queue 2 to transmission path 2. Finally, output the high-definition video of queue 3 to transmission path 2.
在数据倒换过程中需要说明的是，当实际数据总量D大于传输路径2中传输带宽最大值时，也就是传输路径2无法完全承担分配的数据总量时，传输路径2会根据数据流队列的优先级别先进先出，对于后来的数据尾部丢弃。What needs to be explained during the data switching process is that when the actual total amount of data D is greater than the maximum transmission bandwidth in transmission path 2, that is, when transmission path 2 cannot fully bear the total amount of data allocated, transmission path 2 will The priority level is first in first out, and the tail of the subsequent data is discarded.
这里还需要说明的是，当数据采集装置在一个时间段内获取的数据流为一个时，直接将该数据流输出到可用的一条传输路径即可。What needs to be explained here is that, when the data collection device acquires one data stream within a time period, it only needs to directly output the data stream to one available transmission path.
S1033、当所有传输路径均为可用时，按照各传输路径对应的待传输数据量通过各传输路径将数据流传输至中央监控站。S1033. When all transmission paths are available, transmit the data stream to the central monitoring station through each transmission path according to the amount of data to be transmitted corresponding to each transmission path.
同样地，在视频监控业务的2条传输路径网络正常的情况下，当数据调度单元接收到突发的大量数据，导致数据总量D大于2条路径能承载的带宽之和时，按照数据流队列优先级别先进先出，将后进的数据尾部丢弃，从而确保优先级重要的业务得以优先传输。Similarly, when the network of the two transmission paths of the video surveillance service is normal, when the data scheduling unit receives a large amount of bursty data, resulting in the total amount of data D being greater than the sum of the bandwidths that can be carried by the two paths, according to the data flow The priority level of the queue is first in, first out, and the tail of the late data is discarded, so as to ensure that the business with important priority can be transmitted first.
同时，还需要说明的是，当2条路径都可用的情况下，则对所有的数据流同时进行发送。传输路径1和传输路径2分别对往返时延响应度R1、R2和带宽可利用率的值1-a％、1-b％进行反馈，数据采集装置将根据接收到的反馈按照公式(1)、(2)进行分配，保证分配到2条路径的数据量达到均衡，达到最大的传输效率。At the same time, it should also be noted that, when both paths are available, all data streams are sent at the same time. Transmission path 1 and transmission path 2 respectively feed back the values 1-a% and 1-b% of round-trip delay responsivity R1, R2 and bandwidth availability, and the data acquisition device will follow the formula (1) according to the received feedback , (2) Allocation is performed to ensure that the amount of data allocated to the two paths is balanced to achieve the maximum transmission efficiency.
通过步骤S1032或S1033将数据信息分配到可用的传输路径的之后，数据采集装置通过传输路径将数据发送至中央监控站。这里传输路径1可以为光纤，传输路径2可以为4G网络，同样以视频监控业务为例进行说明。当数据从传输路径1即光纤发送时，数据采集装置的将收到的视频数据，即视频信号进行光电转换，并将转换后的光信息传输进入光纤，光信息沿着光纤直接传送到中央监控站。当数据从传输路径2即4G网络发送时，数据采集装置将收到的需发送的视频数据转为射频信号向4G网络发送出去，通过各个4G基站进行转发，最终到达中央监控站。After distributing the data information to the available transmission path through step S1032 or S1033, the data collection device sends the data to the central monitoring station through the transmission path. Here, the transmission path 1 may be an optical fiber, and the transmission path 2 may be a 4G network. The video surveillance service is also used as an example for illustration. When the data is sent from the transmission path 1, that is, the optical fiber, the data acquisition device performs photoelectric conversion on the received video data, that is, the video signal, and transmits the converted optical information into the optical fiber, and the optical information is directly transmitted to the central monitoring along the optical fiber. stand. When the data is sent from the transmission path 2, that is, the 4G network, the data acquisition device converts the received video data to be sent into a radio frequency signal and sends it to the 4G network, forwards it through each 4G base station, and finally reaches the central monitoring station.
本发明实施例提供了一种业务数据传输方法，数据采集装置可以通过多种传输路径将采集到的数据流传输至中央监控站，实现了将有线传输路径与无线网络传输路径实时在线相互切换的功能，对数据进行分流传输，提高了传输效率，避免了因单一组网中断导致的业务数据传输中断。The embodiment of the present invention provides a service data transmission method. The data acquisition device can transmit the collected data stream to the central monitoring station through various transmission paths, realizing the real-time online switching between the wired transmission path and the wireless network transmission path. Function, splitting and transmitting data, improving transmission efficiency, and avoiding interruption of business data transmission caused by interruption of a single network.
实施例二Embodiment two
本发明实施例提供一种业务数据传输方法，应用于中央监控站一侧，如图6所示，所述方法可以包括：The embodiment of the present invention provides a business data transmission method, which is applied to the side of the central monitoring station. As shown in FIG. 6, the method may include:
S201、检测数据采集装置的各传输路径发送的数据信号状态，并根据所述数据信号状态接收由数据采集装置发送的数据流。S201. Detect the status of the data signal sent by each transmission path of the data acquisition device, and receive the data stream sent by the data acquisition device according to the data signal status.
中央监控站先对数据采集装置的各传输路径发送的数据信号进行检测。若数据信号有异常则及时反馈到数据采集装置，确保数据采集装置各传输路径发送的数据信息不发生丢失。若数据信号正常，则正常接收数据采集装置发送的数据信息。The central monitoring station first detects the data signals sent by each transmission path of the data acquisition device. If the data signal is abnormal, it will be fed back to the data acquisition device in time to ensure that the data information sent by each transmission path of the data acquisition device will not be lost. If the data signal is normal, the data information sent by the data acquisition device is normally received.
在检测数据采集装置的各传输路径发送的数据信号时，该数据信号可能出现异常，参见图7，S201可以包括步骤S2011和S2012：When detecting the data signal sent by each transmission path of the data acquisition device, the data signal may be abnormal. Referring to FIG. 7, S201 may include steps S2011 and S2012:

本实施例以在视频监控业务中，数据采集装置的路径1中的有线传输介质中断或者故障的情况为示例进行说明。当数据采集装置的路径1中的有线传输介质为光纤时，由于光纤中断，中央监控站无法检测到数据采集装置的路径1发送的数据信号，产生数据信号异常的告警信号。这里，数据信号异常可以包括接受不到光纤发送的光信号，或者是光功率低于临界值，也可以是链路误码率大于临界值等情况。获取数据信号异常的告警信号后，中央监控站将数据采集装置的路径1发送数据异常的信息反馈到数据采集装置。In this embodiment, in the video monitoring service, the case where the wired transmission medium in the path 1 of the data collection device is interrupted or faulty is taken as an example for illustration. When the wired transmission medium in path 1 of the data acquisition device is an optical fiber, the central monitoring station cannot detect the data signal sent by path 1 of the data acquisition device due to the interruption of the optical fiber, and an alarm signal of abnormal data signal is generated. Here, the abnormality of the data signal may include that the optical signal sent by the optical fiber cannot be received, or the optical power is lower than a critical value, or the bit error rate of the link is greater than the critical value. After obtaining the alarm signal of abnormal data signal, the central monitoring station feeds back the information of abnormal data sent by path 1 of the data acquisition device to the data acquisition device.
等待数据采集装置按照步骤S1032所述方法重新分配数据信息后，中央监控站接收数据采集装置通过路径2发送的数据信息并进行保存。After waiting for the data collection device to redistribute the data information according to the method described in step S1032, the central monitoring station receives and saves the data information sent by the data collection device through path 2.
S2012、当检测到数据采集装置各传输路径发送的数据信号正常时，接收数据采集装置通过各传输路径所发送的数据流。S2012. When it is detected that the data signals sent by each transmission path of the data collection device are normal, receive the data stream sent by the data collection device through each transmission path.
当中央监控站检测到数据信号正常时，分别通过传输路径1和传输路径2接收数据采集装置发送的数据信息并进行保存。When the central monitoring station detects that the data signal is normal, it receives and saves the data information sent by the data acquisition device through the transmission path 1 and the transmission path 2 respectively.
S202、将所接收到的数据流发送到监控客户端。S202. Send the received data stream to the monitoring client.
在接收到数据采集装置发送的数据信息后，中央监控站将所述数据信息发送到监控客户端。对视频监控业务，用户可以通过电脑、电视、手机、平板电脑等监控客户端对监控视频进行查看。After receiving the data information sent by the data collection device, the central monitoring station sends the data information to the monitoring client.
