It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

在其中一个实施例中，提供一种GPS数据传输系统，该系统包括：客户端、服务器、LoRa网关及节点仪；In one of the embodiments, a GPS data transmission system is provided, and the system includes: a client, a server, a LoRa gateway and a node instrument;

第一实施例first embodiment

本实施例提供一种GPS数据传输系统，该系统包括：客户端、服务器、LoRa网关及节点仪；This embodiment provides a GPS data transmission system, and the system includes: a client, a server, a LoRa gateway, and a node instrument;

具体的，客户端即中央客户端，又称为用户端，其是指与服务器相对应，为客户提供本地服务的程序。客户端供用户进行操作，当用户需要获取节点仪的位置坐标信息时，通过用户端向服务器发送获取GPS数据的请求指令，该指令包含所请求的设备的设备编码，即所请求节点仪的设备编码，客户端需确定需要获取GPS数据的节点仪的设备编号。例如，用户通过手动输入所需获取对应节点仪的设备编号，也可以先将所有节点仪的设备编号存储只列表中，从列表中选择需要获取GPS数据的节点仪的设备编号。Specifically, the client is the central client, also known as the client, which refers to a program corresponding to the server and providing local services for the client. The client is for the user to operate. When the user needs to obtain the position and coordinate information of the node instrument, the user sends a request command for obtaining GPS data to the server through the client. The command contains the device code of the requested device, that is, the device of the requested node instrument. code, the client needs to determine the device number of the node instrument that needs to obtain GPS data. For example, the user can manually input the device number of the corresponding node device to be obtained, or first store the device numbers of all node devices in the list, and select the device number of the node device that needs to obtain GPS data from the list.

具体的，LoRa(Long Range Radio，远距离无线电)网关也称为LoRa基站，其是利用LoRa无线调制技术实现远距离数据传输的网关设备。LoRa网关采用工业级32位专用网络处理器及高速4G无线通讯模块设计，支持APN/VPDN无线专网，支持LoRaWAN通信规范，支持GPS高精度时钟同步，具备多频点、多信道的并发处理能力。通过设置LoRa网关，服务器将从客户端接收的请求指令发送至LoRa网关，LoRa网关通过无线通信技术将请求指令广播至节点仪上，实现了节点仪与客户端的无线传输。Specifically, a LoRa (Long Range Radio, long-distance radio) gateway is also called a LoRa base station, which is a gateway device that uses LoRa wireless modulation technology to realize long-distance data transmission. LoRa gateway is designed with industrial-grade 32-bit dedicated network processor and high-speed 4G wireless communication module, supports APN/VPDN wireless private network, supports LoRaWAN communication specification, supports GPS high-precision clock synchronization, and has multi-frequency and multi-channel concurrent processing capabilities . By setting the LoRa gateway, the server sends the request instruction received from the client to the LoRa gateway, and the LoRa gateway broadcasts the request instruction to the node instrument through wireless communication technology, realizing wireless transmission between the node instrument and the client.

具体的，广播是一种信息的传播方式，其是指网络中的某一设备同时向网络中的所有其他设备发送数据，这个数据所能广播到的范围即为广播域。对应的，本申请，LoRa网关通过无线传输技术同时向网络中的所有节点仪发送请求指令。Specifically, broadcasting is a way of disseminating information, which means that a certain device in the network sends data to all other devices in the network at the same time, and the range to which this data can be broadcast is the broadcast domain. Correspondingly, in this application, the LoRa gateway simultaneously sends request instructions to all nodes in the network through wireless transmission technology.

具体的，节点仪获取LoRa网关发送的请求指令，判断请求指令中的设备编码是否与自身编码相匹配；若相匹配，则说明该节点仪为客户端所需要获取GPS数据的节点仪，启动节点仪中的GPS模块，GPS模块进行定位，以获取GPS数据，即节点仪通过GPS模块获取GPS数据，然后节点仪将获取的GPS数据通过服务器转发至客户端，以使客户端能够收到对应的节点仪的GPS数据。本实施例中，请求指令是通过客户端发送，即根据按需使用原则，当用户需要获取GPS数据时，才启动GPS模块进行定位，无需实时进行定位，可以降低节点仪的电能损耗，从而延长节点仪的电池使用寿命。并且对于不是客户端所请求的节点仪，由于发送请求指令中包含的设备编码与其自身编码不匹配，则保持待机状态，进一步降低节点仪的电能损耗。Specifically, the node device obtains the request command sent by the LoRa gateway, and determines whether the device code in the request command matches its own code; if it matches, it means that the node device is the node device that the client needs to obtain GPS data, and starts the node. The GPS module in the instrument, the GPS module performs positioning to obtain GPS data, that is, the node instrument obtains GPS data through the GPS module, and then the node instrument forwards the acquired GPS data to the client through the server, so that the client can receive the corresponding GPS data. GPS data of the node meter. In this embodiment, the request instruction is sent through the client, that is, according to the principle of on-demand use, when the user needs to obtain GPS data, the GPS module is activated for positioning, and real-time positioning is not required, which can reduce the power consumption of the node meter, thereby prolonging the The battery life of the node meter. And for the node instrument that is not requested by the client, since the device code contained in the sending request instruction does not match its own code, it will remain in a standby state, further reducing the power consumption of the node instrument.

具体的，消息队列遥测传输即MQTT(Message Queuing Telemetry Transport，消息队列遥测传输)，其是一种基于轻量级代理的发布或者订阅模式的消息传输协议，运行在TCP协议栈之上，为其提供有序、可靠、双向连接的网络连接保证。且消息队列遥测传输具有以下特点：Specifically, Message Queuing Telemetry Transport is MQTT (Message Queuing Telemetry Transport, Message Queuing Telemetry Transport), which is a light-weight proxy-based publish or subscribe message transport protocol, running on top of the TCP protocol stack, for the Provides an orderly, reliable, two-way connection network connection guarantee. And the message queue telemetry transmission has the following characteristics:

(1)MQTT消息带宽小，设计合理在低功率系统上实施；(1) MQTT message bandwidth is small, and the design is reasonable to implement on low-power systems;

(2)实现MQTT非常简单远程传感器系统上的消息。由于大部分复杂工作都是在服务器上实现的，因此远程系统可以在其他地方使用其资源。(2) It is very simple to implement MQTT messages on remote sensor systems. Since most of the complex work is done on the server, the remote system can use its resources elsewhere.

(3)MQTT用于任务关键型传感器系统，其中发送的任何消息都得到确认和接收至关重要。MQTT允许通过声明其服务质量(QOS)级别来定义消息的重要性。(3) MQTT is used in mission-critical sensor systems where it is critical that any message sent is acknowledged and received. MQTT allows the importance of a message to be defined by declaring its Quality of Service (QOS) level.

因此，服务器与客户端通过MQTT方式进行数据传输，可以降低协议开销，降低客户端的电能损耗，数据传输稳定可靠。Therefore, the data transmission between the server and the client through MQTT can reduce the protocol overhead, reduce the power consumption of the client, and the data transmission is stable and reliable.

在其中一个实施例中，所述请求指令还包括帧头、命令码、循环冗余校验码及结束符，所述帧头、所述设备编码、所述命令码、所述循环冗余校验码及所述结束符依次排列。具体的，循环冗余校验码即CRC8(CyclicRedundancyCheck，循环冗余校验码)；帧头为“$”占用1个字节，节点仪的设备编码为8位字符编码组成，占用8个字节，命令码占用2个字节，循环冗余校验码占用1个字节，结束符为回车换行“\r\n”，占用2个字节。例如，命令码为“61”,CRC8为指令前11个字符编码的校验值。通过将请求指令按所述帧头、所述设备编码、所述命令码、循环冗余校验码及所述结束符依次排列组成，以使得节点仪在解析请求指令时，能更好地判断请求指令中的设备编码是否与自身编码相匹配。在其中一个实施例中，所述请求指令由帧头、设备编码、命令码、循环冗余校验码及所述结束符依次排列组成。本实施例中，命令码为第一命令码，循环冗余校验码为第一循环冗余校验码。In one embodiment, the request instruction further includes a frame header, a command code, a cyclic redundancy check code, and a terminator, the frame header, the device code, the command code, the cyclic redundancy check code, and the cyclic redundancy check code. The verification code and the terminator are arranged in sequence. Specifically, the cyclic redundancy check code is CRC8 (CyclicRedundancyCheck, cyclic redundancy check code); the frame header is "$" and occupies 1 byte, and the device code of the node instrument is composed of 8-bit character code, occupying 8 words section, the command code occupies 2 bytes, the cyclic redundancy check code occupies 1 byte, and the terminator is carriage return and line feed "\r\n", which occupies 2 bytes. For example, the command code is "61", and CRC8 is the check value encoded by the first 11 characters of the command. By arranging the request command in sequence according to the frame header, the device code, the command code, the cyclic redundancy check code and the terminator, the node instrument can better judge when parsing the request command. Whether the device encoding in the request command matches its own encoding. In one embodiment, the request instruction is composed of a frame header, a device code, a command code, a cyclic redundancy check code, and the terminator in sequence. In this embodiment, the command code is the first command code, and the cyclic redundancy check code is the first cyclic redundancy check code.

在其中一个实施例中，所述LoRa网关处于长连接状态；所述服务器以套接字的方式将所述请求指令发送至所述LoRa网关。具体的，长连接指在一个连接上可以连续发送多个数据包，在连接保持期间，如果没有数据包发送，需要双方发链路检测包。套接字即socket，其是对网络中不同主机上的应用进程之间进行双向通信的端点的抽象。一个套接字就是网络上进程通信的一端，提供了应用层进程利用网络协议交换数据的机制。从所处的地位来讲，套接字上联应用进程，下联网络协议栈，是应用程序通过网络协议进行通信的接口，是应用程序与网络协议根进行交互的接口，套接字是通信的基石，是支持TCP(Transmission Control Protocol，传输控制协议)/IP(Internet Protocol，国际网络协议)协议的路通信的基本操作单元。本实施例中，服务器获取到客户端发送过来的请求指令，向处于长连接状态的LoRa网关以纯socket的方式发送请求指令，从而实现服务器与LoRa网关的通信。In one embodiment, the LoRa gateway is in a long connection state; the server sends the request instruction to the LoRa gateway in a socket manner. Specifically, a long connection means that multiple data packets can be continuously sent on one connection. During the connection maintaining period, if no data packets are sent, both parties need to send link detection packets. A socket is a socket, which is an abstraction of an endpoint for bidirectional communication between application processes on different hosts in a network. A socket is one end of process communication on the network, providing a mechanism for application layer processes to exchange data using network protocols. From the perspective of its position, the socket is connected to the application process and the network protocol stack is connected. It is the interface for the application to communicate through the network protocol, and it is the interface for the application to interact with the network protocol root. The socket is the communication interface. The cornerstone is the basic operation unit of road communication that supports TCP (Transmission Control Protocol, Transmission Control Protocol)/IP (Internet Protocol, Internet Protocol) protocol. In this embodiment, the server obtains the request instruction sent by the client, and sends the request instruction to the LoRa gateway in a long connection state in a pure socket manner, thereby realizing the communication between the server and the LoRa gateway.

在其中一个实施例中，所述节点仪用于将所述GPS数据按预设格式进行清洗，得到清洗后的所述GPS数据，并将清洗后的所述GPS数据发送至服务器。具体的，清洗即数据清洗，其是发现并纠正数据文件中可识别的错误的最后一道程序，包括检查数据一致性，处理无效值和缺失值等。因为数据仓库中的数据是面向某一主题的数据的集合，这些数据从多个业务系统中抽取而来而且包含历史数据，这样就避免不了有的数据是错误数据、有的数据相互之间有冲突，这些错误的或有冲突的数据显然是我们不想要的，称为“脏数据”。数据清洗的目的是为了将很多种不同的信息安全检测的工具统一成平台专用格式，并且提取有用的数据，用于后续流程的数据流转。本实施例中，GPS模块采集GPS数据，节点仪将采集的GPS按预设格式进行清洗，即将GPS数据设置为预设格式，并将清洗后的GPS数据发送至服务器，从而可以保证GPS数据传输的完整性。在其中一个实施例中，所述预设格式为JSON(JavaScript Object Notation，JS，对象简谱)格式。JSON格式为如下：In one embodiment, the node instrument is configured to clean the GPS data in a preset format, obtain the cleaned GPS data, and send the cleaned GPS data to a server. Specifically, cleaning is data cleaning, which is the last procedure to find and correct identifiable errors in data files, including checking data consistency, dealing with invalid and missing values, and so on. Because the data in the data warehouse is a collection of data oriented to a certain topic, these data are extracted from multiple business systems and contain historical data, so it is inevitable that some data are wrong data, and some data are interrelated with each other. Conflicts, these erroneous or conflicting data that we obviously don't want, are called "dirty data". The purpose of data cleaning is to unify many different information security detection tools into a platform-specific format, and extract useful data for data flow in subsequent processes. In this embodiment, the GPS module collects GPS data, and the node meter cleans the collected GPS according to the preset format, that is, sets the GPS data to the preset format, and sends the cleaned GPS data to the server, so as to ensure the GPS data transmission completeness. In one embodiment, the preset format is a JSON (JavaScript Object Notation, JS, Object Notation) format. The JSON format is as follows:

{"GPS":"JJJJJJJJJJJEWWWWWWWWWWNHHHHHvvYYYYMMDDTTMM SS"}{"GPS":"JJJJJJJJJJJEWWWWWWWWWWNHHHHHvvYYYYMMDDTTMM SS"}

为了便于理解举一具体实施例，所采集的GPS数据为：In order to facilitate understanding, a specific embodiment is given, the collected GPS data is:

{"GPS":"11844.00253E3204.22579N+002720720200211135604"}{"GPS":"11844.00253E3204.22579N+002720720200211135604"}

上述JSON格式中各字符的所表达的意思为：The meaning of each character in the above JSON format is:

(1)11个J表示经度的意思，该实施例中表示经度为118度44分，0.00253*60＝0.1518秒。(1) 11 Js represent longitude, and in this embodiment, the longitude is 118 degrees and 44 minutes, and 0.00253*60=0.1518 seconds.

(2)E代表东经的意思，如果是W就是西经。(2) E means east longitude, if it is W, it means west longitude.

(3)10个W表示纬度的意思，该实施例中表示纬度为32度04分，0.22579*60＝13.5474秒。(3) 10 Ws represent the meaning of latitude. In this embodiment, it represents that the latitude is 32 degrees and 04 minutes, and 0.22579*60=13.5474 seconds.

(4)N代表北半球意思，南半球就是用S表示。(4) N stands for the northern hemisphere, and S for the southern hemisphere.

(5)6个H代表高度，最高999999，单位为分米。该实施例中表示高度27.2m。(5) 6 Hs represent height, the maximum is 999999, and the unit is decimeter. In this example, the height is 27.2 m.

(6)2个V在使用的卫星个数。该实施例表示卫星数7个。(6) The number of satellites in use by 2 V. This example shows seven satellites.

(7)UTC时间，年月日时分秒。(7) UTC time, year, month, day, hour, minute, second.

如此，通过将GPS数据清洗成JSON格式，可以清楚地表示节点仪中GPS模块所采集的GPS数据。且清洗后的GPS数据所占用资源少，传输效率高，更加稳定。In this way, by cleaning the GPS data into JSON format, the GPS data collected by the GPS module in the node instrument can be clearly represented. Moreover, the cleaned GPS data occupies less resources, has high transmission efficiency and is more stable.

具体的，所述节点仪用于根据所约定报文及清洗后的所述GPS数据，得到回传数据报文，即将GPS数据代入约定报文中，从而得到回传数据报文。该回传数据报文包括包长、命令码、设备编码、清洗后的GPS数据及循环冗余检验码，包长、命令码、设备编码、清洗后的GPS数据及循环冗余检验码依序排列。在其中一个实施例中，所述回传数据报由包长、命令码、设备编码、清洗后的GPS数据及循环冗余检验码组成，包长、命令码、设备编码、清洗后的GPS数据及循环冗余检验码依序排列。其中，包长为4个字节(int整型)，包长为整个报文的长度，命令码2个字节，例如：命令码为“61”；设备编码为8个字节，该设备编码为获得GPS数据所对应的节点仪的设备编码，也就是客户端所请求的设备编码。循环冗余校验码占用一个字节，循环冗余校验码为报文的校验和；清洗后的GPS数据即JSON格式的GPS数据。通过将GPS数据以约定报文的形式进行传输，使得服务器在接收到回传数据报文时，方便对报文解析，从而更好地提取回传数据报文中所包含的GPS数据，也保证了GPS数据传输的稳定性。本实施例中，所述命令码为第二命令码，所述循环冗余校验码为第二循环冗余校验码。Specifically, the node device is configured to obtain the return data message according to the agreed message and the cleaned GPS data, that is, substitute the GPS data into the agreed message to obtain the return data message. The returned data message includes packet length, command code, device code, cleaned GPS data and cyclic redundancy check code. The packet length, command code, device code, cleaned GPS data and cyclic redundancy check code are in sequence. arrangement.
