Abstract

The invention discloses a data reporting method of a power utilization information acquisition terminal based on a random value, relating to the field of communication of power systems. The data reporting mode of the current data acquisition system can not make a compromise between the magnitude of communication flow and the distribution uniformity of the communication flow. In the invention, a master station is provided with a task setup module, wherein the task setup module sets up tasks for terminals, sets a data reporting time period for each task and randomly generates data reporting time points for each terminal in the data reporting time period. Since the task setup module randomly generates data reporting time points for each terminal in the data reporting time period of each task and the reporting time points are uniformly distributed in the reporting time period, the invention avoids the possible unexpected load caused by the active reporting of a terminal, balances the message reporting time and prevents the unexpected load from impacting the communication channel and the master station.

一种基于随机值的用电信息采集终端数据上送方法A random value-based method for sending data to a power consumption information collection terminal

【技术领域】【Technical field】

本发明涉及电力系统通信领域，尤指一种基于随机值的用电信息采集终端数据上送方法。The invention relates to the field of power system communication, in particular to a random value-based method for sending data to a power consumption information collection terminal.

【背景技术】【Background technique】

数据采集系统的数据上送方式大体上分两种方法：There are generally two ways to send data to the data acquisition system:

1、主站轮询方式。这种方式下，主站循环对各终端进行召测。单线程时，一般不会产生通道或者主机处理能力的瓶颈；多线程时，可以根据通道容量或者主机处理能力决定线程数，一般也不会出现不可控的情况。但存在的不足是，每次数据上送之前都要下发一次命令，大大增加了通信流量。1. The polling method of the master station. In this way, the master station calls and tests each terminal in a loop. When single-threaded, there will generally not be a bottleneck in the processing capacity of the channel or the host; when multi-threaded, the number of threads can be determined according to the capacity of the channel or the processing capacity of the host, and generally there will be no uncontrollable situation. However, the disadvantage is that a command must be issued before each data upload, which greatly increases the communication traffic.

2、终端主动上送方式。这种方式下，通讯流量大大减少，但通常固定时间的数据上送将带来突发性的负载，带来通信通道和通信处理设备的巨大压力。2. The terminal actively uploads the method. In this way, the communication traffic is greatly reduced, but usually the fixed-time data upload will bring sudden loads, which will bring huge pressure on the communication channels and communication processing equipment.

为了解决终端主动上送可能带来的突发性负载，可以考虑采取分组的方式，每一组规定一个数据上送时间。但是这种方式需要将终端分成相当多的组并且手工配置上送时间才能得到大致的均衡上送，而且在终端增加时，很难做到动态的调整。In order to solve the sudden load that may be caused by the active uploading of the terminal, the grouping method can be considered, and each group specifies a data sending time. However, in this way, it is necessary to divide the terminals into quite a few groups and manually configure the sending time to obtain roughly balanced sending, and it is difficult to make dynamic adjustments when the number of terminals increases.

在任务制定模块制定任务前，需根据通道带宽和主站处理能力来确定每秒钟最大处理的报文数量，在此基础之上，根据终端数量计算处理所有终端对应于每一任务的报文所需的最短时间；任务制定模块根据任务数量及每一任务数据处理的最短时间确定对应任务数据的允许上送的时间范围。每一类终端任务数据上送时间范围在业务允许的时间范围内，按照不少于最短时间的要求确定，终端上送任务数据的时间段大于或等于处理该任务数据的最短时间。由于在一任务的时间段内，数据上送时间点随机分布，故可避免网络和服务器的冲击。Before the task formulation module formulates tasks, it is necessary to determine the maximum number of messages processed per second according to the channel bandwidth and the processing capacity of the master station.

如图1所示，本发明所涉及主站、终端及两者之间的通讯，主站的任务制定模块通过主站的通讯模块将任务下达给每一个终端的通讯模块，所述终端通讯模块收到任务后，通知一设于终端的任务调度模块，任务调度模块在任务规定的上送时间段内通过终端通讯模块将任务数据上送给主站的通讯模块，主站的通讯模块将任务数据交于一设于主站的任务数据解析处理模块解析处理。As shown in Figure 1, the master station, the terminal and the communication between the two involved in the present invention, the task formulation module of the master station assigns the task to the communication module of each terminal through the communication module of the master station, and the terminal communication module After receiving the task, notify a task scheduling module located in the terminal, and the task scheduling module will send the task data to the communication module of the master station through the terminal communication module within the time period specified in the task, and the communication module of the master station will send the task The data is analyzed and processed by a task data analysis and processing module located at the master station.

如图2所示，本发明包括以下步骤：As shown in Figure 2, the present invention comprises the following steps:

1)根据通道带宽和主站处理能力来确定每秒钟最大处理的报文数量；1) Determine the maximum number of messages processed per second according to the channel bandwidth and the processing capacity of the master station;

2)根据终端数量计算处理所有终端对应于每一任务的报文所需的最短时间；2) Calculate the minimum time required to process the messages of all terminals corresponding to each task according to the number of terminals;

3)根据任务数量及每一任务数据处理的最短时间计算对应任务数据的允许上送的时间范围；3) Calculate the allowable upload time range of corresponding task data according to the number of tasks and the shortest time for data processing of each task;

4)任务制定模块为每一个终端制定任务、设定每一个终端每个任务的数据上送时间段，并在该上送时间段内随机生成各终端的数据上送时间点。4) The task formulation module formulates a task for each terminal, sets a data upload time period for each task of each terminal, and randomly generates data upload time points for each terminal within the upload time period.

5)任务制模块通过主站通讯模块将任务分发给每一个终端的任务调度模块。5) The task system module distributes tasks to the task scheduling module of each terminal through the communication module of the master station.

6)任务调度模块将终端数据采集模块的数据在任务规定的上送时间段内的任一时间点随机通过终端通讯模块将任务数据上送给主站的通讯模块。6) The task scheduling module sends the data of the terminal data acquisition module to the communication module of the master station randomly through the terminal communication module at any time point within the uploading time period specified in the task.

主站的任务制定模块下达的每项任务包含数据上送基准时间、上送时间间隔以及数据内容。Each task issued by the task formulation module of the master station includes the reference time for data upload, the upload time interval and the data content.

如：当有两个不同任务时：For example: when there are two different tasks:

1、首先，按照业务的特点，人工确定零点电量数据在每天0点15分到1点之间上送，每小时的负荷数据在整点后的0分到15分钟上送。零点电量任务的数据内容包括正向有功总、峰、谷和最大需量，小时负荷任务的数据内容包括有功功率、无功功率、三相电流、三相电压。当一个终端需要配置多个任务时，每一类任务的上送时间范围需要综合考虑负载均衡。例如，一个20万台终端的用电信息采集系统，需要配置两个任务：每天一次上送零点电量数据、每小时一次采集整点负荷数据。假设零点抄表数据在每天0:00-0:15上送，整点负荷数据在每个小时的0分-10分上送，那么，按照随机的概率分布，在每个小时的0-10分，每秒钟有333条整点负荷报文上送；而在0:00-0:15，则每秒钟有222条零点电量报文上送，因而在0:00-0:10，每秒钟有555条报文上送。如果将零点负荷任务错开，安排在0:10-0:25上送，则0:00-0:10期间，仍然保持每秒333条报文。1. First, according to the characteristics of the business, it is manually determined that the zero-point power data is sent between 0:15 and 1:00 every day, and the hourly load data is sent between 0 and 15 minutes after the hour. The data content of the zero-point power task includes the total forward active power, peak, valley and maximum demand, and the data content of the hourly load task includes active power, reactive power, three-phase current, and three-phase voltage. When a terminal needs to configure multiple tasks, the upload time range of each type of task needs to consider load balancing comprehensively. For example, a power consumption information collection system with 200,000 terminals needs to be configured with two tasks: sending zero-point electricity data once a day and collecting hourly load data once an hour. Assuming that the zero-point meter reading data is sent at 0:00-0:15 every day, and the hourly load data is sent at 0-10 minutes per hour, then, according to the random probability distribution, at 0-10 minutes per hour At 0:00-0:15, there are 222 zero-point load messages sent per second, so at 0:00-0:10, 555 packets are sent every second. If the zero-point load task is staggered and scheduled to be sent at 0:10-0:25, then 333 messages per second will still be maintained during 0:00-0:10.

2、其次，主站给终端下发设置命令，并在每次设置时，主站自动按照上述要求随机生成上送基准时间，即零点电量数据任务为900秒～3600秒之间的随机值，小时负荷数据任务为0秒～900秒之间的随机值，上送间隔时间分别为1天和1小时。2. Secondly, the master station sends a setting command to the terminal, and every time it is set, the master station automatically generates a random reference time for uploading according to the above requirements, that is, the zero-point power data task is a random value between 900 seconds and 3600 seconds, The hourly load data task is a random value between 0 seconds and 900 seconds, and the upload intervals are 1 day and 1 hour respectively.

3、最终，每一终端各自按照主站设定的时间上送任务数据。当终端数量达到一定规模后，通过步骤2确定的时间，可以实现同一任务在规定时间段的数据均衡上送；按照步骤1，合理确定各任务的上送时间范围可以实现不同任务之间数据的均衡上送。3. Finally, each terminal sends task data according to the time set by the master station. When the number of terminals reaches a certain scale, through the time determined in step 2, the balanced data uploading of the same task in the specified time period can be realized; according to step 1, the reasonable determination of the uploading time range of each task can realize the data sharing between different tasks Balanced upload.

以上图1、2所示的一种基于随机值的用电信息采集终端数据上送方法是本发明的具体实施例，已经体现出本发明实质性特点和进步，可根据实际的使用需要，在本发明的启示下，对其进行形状、结构等方面的等同修改，均在本方案的保护范围之列。The above random value-based power consumption information collection terminal data sending method shown in Figures 1 and 2 is a specific embodiment of the present invention, which has already reflected the substantive features and progress of the present invention, and can be used according to actual needs. Under the enlightenment of the present invention, equivalent modifications to it in terms of shape, structure, etc., all fall within the scope of protection of this proposal.
