技术领域technical field
本实用新型涉及电能表数据采集，尤其涉及一种适合于无移动信号覆盖区域的电能表数据远程采集系统。The utility model relates to electric energy meter data collection, in particular to an electric energy meter data remote collection system suitable for areas without mobile signal coverage.
背景技术Background technique
电力资源是支持用电用户正常生活和生产的重要资源，对于用电用户电力统计及收费是实现用电管理的关键环节。随着电能表数据采集技术的发展，电网公司不断提高10kV中压电力用户的电能表数据自动采集率，大幅降低传统人工抄表作业强度。电能表数据自动采集一般是依靠电信运营商的移动通信网络实现远程数据的抄读。然而，在偏远山区，受地形条件影响，区域内无移动信号覆盖或者移动信号不稳定，现有技术中无法通过移动通信网络直接采集电能表数据，因此只能采用人工抄读电能表数据的方式。然而采用人工抄读电能表数据，不仅费时费力，而且难以保证数据的实时性，其次容易出现漏抄重抄的现象，导致抄表效率低，结果不准。Power resources are important resources to support the normal life and production of power users, and electricity statistics and charging for power users are the key links to realize power management. With the development of energy meter data acquisition technology, power grid companies have continuously increased the automatic energy meter data collection rate of 10kV medium-voltage power users, greatly reducing the intensity of traditional manual meter reading operations. The automatic collection of electric energy meter data generally relies on the mobile communication network of the telecom operator to realize the remote data reading. However, in remote mountainous areas, affected by terrain conditions, there is no mobile signal coverage or unstable mobile signals in the area. In the prior art, it is impossible to directly collect electric energy meter data through the mobile communication network, so manual reading of electric energy meter data can only be used. . However, using manual reading of electric energy meter data is not only time-consuming and laborious, but also difficult to ensure the real-time performance of the data. Secondly, it is prone to omissions and double-copying, resulting in low meter reading efficiency and inaccurate results.

In the step of correspondingly sending the response message to the medium-voltage carrier slave machine, according to the corresponding connection between the medium-voltage carrier slave machine 70' and the electric energy meter group 80' in the electric energy meter data remote collection system 200, the specific implementation method is as follows: The medium voltage carrier slave 1 sends the collection message to the energy meter group 1 (that is, the electric energy meters 11, 12, ... 1m in the electric energy meter group 1), and the medium voltage carrier slave 2 sends the collection message to the electric energy meter group 2 , and so on, the medium voltage carrier slave machine n sends the collection message to the energy meter group n; The medium-voltage carrier slave 1 and the energy meter group 2 send the response message to the medium-voltage carrier slave 2, and so on, and the electric energy meter group n sends the response message to the medium-voltage carrier slave n.
