Problems solved by technology
[0002] Rural power distribution line faults occur frequently, especially in bad weather, which not only brings a huge repair workload to grass-roots operation managers and production technicians, but also causes serious damage to people's production and life. have a certain impact
[0003] At present, there is no monitoring equipment on the line, so when there is a trip and power failure, the power supply department often does not know where the fault point is. The workload of front-line personnel is more likely to cause mis-scheduling and misoperation, which may cause power distribution accidents or personal safety accidents

Embodiment Construction
[0027] The present invention is described in detail below in conjunction with accompanying drawing:
[0028] Such as figure 1 As shown, a comprehensive measurement and control system for a 10kV line of an intelligent agricultural network includes a monitoring center 11 of a monitoring master station and a GPRS measurement and control terminal 1 (or a control terminal, the model is K4GA22-509C), and the monitoring center 11 communicates with the GPRS measurement and control terminal. The GPRS measurement and control terminal 1 is connected to the opening relay 2 and the closing relay 3, the transfer terminal block 4 and the three-phase three-wire electric energy metering connection block 5, and the power contacts of the opening relay 2 and the closing relay 3 pass through the transfer terminal block 4 It is connected to the 220V external power supply 6, and the other contact point of the opening relay 2 and the closing relay 3 is connected to the vacuum circuit breaker 9 throug...

The invention discloses an intelligent rural power grid 10kV line integrated measurement and control system based on wireless communication, and the system comprises a monitoring center of a monitoring main station, and a GPRS measurement and control terminal. The monitoring center communicates with the GPRS measurement and control terminal, and the GPRS measurement and control terminal communicates with the monitoring center through a wireless receiving and transmission circuit. The monitoring center is connected with a display device, and the GPRS measurement and control terminal is also connected with a body detection circuit. The body detection circuit enables the detection information whether there is a person to be transmitted to the monitoring center, and the monitoring center carries out timely planning operation conveniently according to the information whether there is a person on site or not. The system is based on terminal detection equipment and the GPRS technology, displays the switching states of a column switch of a 10kV line in real time, and also displays the voltage, current, power and power factors. The terminal will actively report the change of the switching state of the switch, and timely reminds the main station of the change, thereby enabling a fault to be solved as quickly as possible.
Description
technical field [0001] The invention relates to the field of agricultural network monitoring, in particular to an intelligent agricultural network 10kV line comprehensive measurement and control system based on wireless communication. Background technique [0002] Rural power distribution line faults occur frequently, especially in bad weather, which not only brings a huge repair workload to grass-roots operation managers and production technicians, but also causes serious damage to people's production and life. had a certain impact. [0003] At present, there is no monitoring equipment on the line, so when there is a trip and power failure, the power supply department often does not know where the fault point is. The workload of front-line personnel is more likely to cause mis-scheduling and misoperation, which may cause power distribution accidents or personal safety accidents. Contents of the invention [0004] In order to solve the deficiencies in the prior art, the ...
