Description
技术领域technical field
本发明涉及电力数据采集系统领域，具体涉及一种用于电量多数据源自动替代的方法。The invention relates to the field of electric power data acquisition systems, in particular to a method for automatic substitution of multiple data sources of electric power.
背景技术Background technique
电能量信息采集系统实现对电量数据的监控、管理、分析以及信息发布，在这样的大型数据库应用系统中，采集的实时数据类型种类繁多，数据总量庞大。由于通信信道和数据量阻塞等原因，会导致部分数据采集缺失。一方面，由于系统的采集服务器、应用服务器和数据库服务器往往部署在不同的地方，相互之间的网络拓扑比较复杂，如果按照一般的流程将采集数据存储到数据库中，一旦网络出现异常或者应用模块之间出现问题而导致数据不能正常存储在数据库中，会造成数据的缺失，影响系统的运行效果和后续流程的正常进行。而系统在网络异常或者软件异常恢复以后对缺失数据进行的补偿性采集和存储降低了系统的运行效率。The electric energy information collection system realizes the monitoring, management, analysis and information release of electric power data. In such a large-scale database application system, there are various types of real-time data collected and the total amount of data is huge. Due to reasons such as communication channel and data volume congestion, some data collection will be missing. On the one hand, because the collection server, application server, and database server of the system are often deployed in different places, the network topology among them is relatively complicated. If the collection data is stored in the database according to the general process, once the network is abnormal or the application module If there is a problem between them, the data cannot be stored in the database normally, which will cause the loss of data and affect the operation effect of the system and the normal progress of the follow-up process. However, the compensatory collection and storage of missing data by the system after the network abnormality or software abnormality recovery reduces the operating efficiency of the system.

具体实施方式Detailed ways
本发明提供一种用于电量多数据源自动替代的方法，基于一种用于电量多数据源自动替代的系统，该系统的结构示意图如图1所示，包括应用服务器、中间件服务器和数据库服务器，应用服务器和数据库服务器通过中间件服务器连接通信或者直接连接通信。基于该系统的方法流程图如图2所示，包括：The present invention provides a method for automatic replacement of multiple data sources of electricity, based on a system for automatic replacement of multiple data sources of electricity, the structural diagram of the system is shown in Figure 1, including an application server, a middleware server and a database The server, the application server and the database server communicate through the middleware server connection or direct connection communication. The flow chart of the method based on the system is shown in Figure 2, including:
步骤S1，应用服务器对采集的电量数据进行分析，确定有电量缺失数据时，对该电量缺失数据进行封装后传入中间件服务器。In step S1, the application server analyzes the collected power data, and when it is determined that there is power missing data, the missing power data is packaged and transmitted to the middleware server.
步骤S2，中间件服务器根据封装后的电量缺失数据按照优先级分配顺序和替代规则依次进行电量缺失数据的数据源替代形成新的封装的电量数据。In step S2, the middleware server replaces the data source of the missing power data in order according to the priority distribution sequence and the replacement rule according to the packaged power missing data to form new packaged power data.
步骤S3，电量缺失数据的数据源替代成功时将形成的新的封装的电量数据存入数据库服务器。In step S3, when the data source of the power missing data is replaced successfully, the new packaged power data is stored in the database server.
应用服务器与数据库服务器相连接，步骤S1中，应用服务器从数据库服务器读取采集的电量数据，并且该读取的采集的电量数据是一定期限内采集的电量数据，该一定期限可以根据采集电量数据的周期或者用户需求进行设定。The application server is connected to the database server. In step S1, the application server reads the collected power data from the database server, and the read collected power data is the power data collected within a certain period, and the certain period can be based on the collected power data. The cycle or user needs are set.
如图3所示为本发明提供的一种用于电量多数据源自动替代的方法的实施例的流程图，由图3可知，步骤S1中，应用服务器对采集的电量数据进行分析后判断没有电量缺失数据时，直接结束该数据源自动替代的过程。并且应用服务器与中间件服务器之间的网络连接正常且中间件服务器运行正常时，应用服务器直接调用中间件接口将封装后电量缺失数据传入到中间件服务器中，若中间件服务器存在异常或者网络连接出现异常时，应用服务器记录该异常事件。As shown in Figure 3, it is a flow chart of an embodiment of a method for automatically replacing multiple data sources of electricity provided by the present invention. It can be seen from Figure 3 that in step S1, the application server analyzes the collected electricity data and judges whether When the power data is missing, the process of automatically replacing the data source will be ended directly. And when the network connection between the application server and the middleware server is normal and the middleware server is running normally, the application server directly calls the middleware interface to transmit the packaged power loss data to the middleware server. If the middleware server is abnormal or the network When the connection is abnormal, the application server records the abnormal event.
步骤S2中，数据源替代包括副表替代、对端线路表替代、遥测数据替代和其他表替代，In step S2, the data source replacement includes subtable replacement, peer line table replacement, telemetry data replacement and other table replacement,
主副表是指在同一个计量点装设两块同等级的关口表，公用同一套电压互感器、电流互感器和二次回路，事先指定其中一块表作为主表，供电量结算使用，另一块表作为副表，其电量做为参考使用；对端线路表是指在线路两端同时装设电能表，用其中一块表的数据来替代对端电能表的数据；遥测数据替代为用通过传感器接收到的被遥测终端的数据进行替代。优先级分配顺序即选择数据源替代表的顺序，用户可以根据需求或者实际安装情况对该优先级分配顺序进行设定。替代规则分为正常替代和交叉替代，指根据电表接线等原理决定；正常替代是指用正向有/无功电量替代正向有/无功电量，反向有/无功电量替代反向有/无功电量；交叉替代是指用正向有/无功电量替代反向有/无功电量，反向有/无电量替代正向有/无功电量。The main and auxiliary meters refer to the installation of two gateway meters of the same level at the same metering point, sharing the same set of voltage transformers, current transformers and secondary circuits. One meter is used as a secondary meter, and its power is used as a reference; the opposite end line meter refers to the electric energy meter installed at both ends of the line, and the data of one of the meters is used to replace the data of the opposite end electric energy meter; the telemetry data is replaced by The data received by the sensors are replaced by the data from the telemetry terminals. The priority assignment order is the order in which data source alternative tables are selected, and the user can set the priority assignment order according to requirements or actual installation conditions. Substitution rules are divided into normal substitution and cross substitution, which refer to the decision based on the principles of ammeter wiring; normal substitution refers to replacing forward active/reactive power with forward active/reactive power, and replacing reverse active/reactive power with reverse active/reactive power. /reactive energy; cross substitution refers to replacing the reverse active/reactive energy with the positive active/reactive energy, and replacing the positive active/reactive energy with the reverse active/non-active energy.
步骤S3中，如果数据源替代不成功，则将数据源替代不成功的失败事件信息存入数据库服务器中，该失败事件信息包括数据源替代事件和替代失败原因等。电量缺失数据的数据源替代成功时，将形成的新的封装的电量数据存入数据库服务器的分布式缓存和对象数据库中，分布式缓存是指分布在大量物理机器中的数据内存缓存建立的内存数据库，对象数据库是指装有商业数据库软件的数据库服务器。In step S3, if the replacement of the data source is unsuccessful, the failure event information of the unsuccessful data source replacement is stored in the database server, and the failure event information includes the data source replacement event and the reason for the replacement failure. When the data source of power missing data is replaced successfully, the newly encapsulated power data will be stored in the distributed cache and object database of the database server. Distributed cache refers to the memory established by the data memory cache distributed in a large number of physical machines Database, object database refers to a database server with commercial database software installed.
如果分布式缓存或对象数据库获取了该形成的新的封装的电量数据，则数据库服务器通过调用接口向应用服务器发送结果信息，应用服务器根据结果信息刷新采集的电量数据或者弹出提示框提示采集的电量数据需要更新。如果分布式缓存和对象数据库均未获取该形成的新的封装的电量数据，则数据库服务器向中间件服务器返回异常信息。If the distributed cache or object database acquires the newly-formed packaged power data, the database server sends the result information to the application server through the call interface, and the application server refreshes the collected power data or pops up a prompt box to prompt the collected power according to the result information Data needs to be updated. If neither the distributed cache nor the object database acquires the newly-formed encapsulated power data, the database server returns exception information to the middleware server.
最后应当说明的是：以上实施例仅用以说明本发明的技术方案而非对其限制，尽管参照上述实施例对本发明进行了详细的说明，所属领域的普通技术人员应当理解：依然可以对本发明的具体实施方式进行修改或者等同替换，而未脱离本发明精神和范围的任何修改或者等同替换，其均应涵盖在本发明的权利要求范围当中。Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
