技术领域 technical field
本发明属于电力行业维护管理技术领域。 The invention belongs to the technical field of electric power industry maintenance management.
背景技术 Background technique
在大型货物批发超市、集贸市场以及各种人员货物密集的公共场所，都不同程度地存在着供电线路架设不规范、私拉乱扯的现象，带来了极大的火灾隐患。目前，除了加强供电安全管理之外，并没有特别有效的技术防范手段。因此，针对中国民间集贸市场的特殊情况，在用电检测上运用技术手段加强管理，是及早发现供电隐患的重要内容。有针对性地开发相应的检测设备是十分必要的。 In large-scale goods wholesale supermarkets, bazaars, and various public places where people and goods are densely populated, there are irregularities in the erection of power supply lines to varying degrees, and the phenomena of private pulling and chattering have brought great fire hazards. At present, in addition to strengthening the safety management of power supply, there is no particularly effective technical prevention method. Therefore, in view of the special situation of China's folk bazaars, using technical means to strengthen management in electricity detection is an important part of early detection of hidden dangers in power supply. It is very necessary to develop corresponding detection equipment in a targeted manner.
发明内容 Contents of the invention
本发明的目的是随时监测大型集贸市场每个用户的瞬时电流变化，为供电安全提供预警信息。 The purpose of the invention is to monitor the instantaneous current change of each user in a large bazaar at any time, so as to provide early warning information for power supply safety.
本发明的技术方案是：在每个用户的电度表前安装一个电流检测探头，将瞬间电流信号经A/D转换后进行地址编码调制，再通过电力载波调制器接入供电线路，在总控室的供电线路上接入电力载波调制器，通过解码获取每一个用户的瞬间电流数值，计算机主控程序收集储存所有用户瞬间电流数值，通过比较原始数据筛选出电流瞬时超标用户，在计算机界面上显示预警信息。 The technical solution of the present invention is: install a current detection probe in front of each user's watt-hour meter, convert the instantaneous current signal through A/D and perform address coding modulation, and then connect the power supply line through the power carrier modulator, The power supply line of the control room is connected to the power carrier modulator, and the instantaneous current value of each user is obtained by decoding. The computer main control program collects and stores the instantaneous current value of all users, and screens out the users whose current exceeds the limit instantaneously by comparing the original data. On the computer interface Display warning information.
本发明的有益效果：本发明针对公共场所供电线路不规范和私拉乱扯电线造成的短路隐患，在每个供电用户接口处设置瞬间电流检测探头，并进行地址编码，将检测数据通过供电线路汇集到配电室的计算机上，实时显示供电安全情况，及时发现电流过载隐患，提供预警信息以防范由于电线发热导致的火灾事故。 Beneficial effects of the present invention: the present invention aims at short-circuit hidden dangers caused by irregular power supply lines in public places and private pulling of electric wires. An instantaneous current detection probe is installed at each power supply user interface, and address coding is performed, and the detection data is passed through the power supply line Gathered to the computer in the power distribution room, the real-time display of the power supply safety situation, timely detection of current overload hazards, and early warning information to prevent fire accidents caused by wire heating.

具体实施方式 Detailed ways
在集贸市场等公共场所每个用户的电度表前安装一个电流检测探头，将该用户的瞬间电流信号经A/D转换后进行地址编码调制，得到一个具有唯一地址编码的瞬间电流检测值，再通过电力载波调制器接入供电线路，在总控室的供电线路上接入电力载波调制器，解调出前述用户的瞬间电流检测值。同样方法，通过解码可分别获取每一个用户的瞬间电流数值，由于计算机主控程序内存储有所有用户的地址码信息，将用户的瞬间电流数值通过对比原始数据，筛选出电流瞬间超标用户，在计算机界面上显示出相应的预警信息。 Install a current detection probe in front of each user's watt-hour meter in public places such as bazaars, and perform address code modulation on the user's instantaneous current signal after A/D conversion to obtain an instantaneous current detection value with a unique address code. , and then access the power supply line through the power carrier modulator, and connect the power carrier modulator to the power supply line of the main control room, and demodulate the instantaneous current detection value of the aforementioned users. In the same way, the instantaneous current value of each user can be obtained separately by decoding. Since the address code information of all users is stored in the main control program of the computer, the instantaneous current value of the user is compared with the original data to screen out the users whose current exceeds the standard instantaneously. The corresponding warning information is displayed on the computer interface.
本发明利用电力载波调制器进行信息传递，为保证检测数据的可靠性，其使用范围应在一个供电小区之内。 The present invention uses the power carrier modulator to transmit information, and in order to ensure the reliability of the detection data, its application range should be within a power supply area.
