Embodiment 1

[0038] The invention provides an intelligent detection system for the position of the pressing plate, such as figure 1 As shown, it includes at least 2 intelligent pressure plates, repeaters and host computers; the various intelligent pressure plates are connected in a cascade manner, and the repeater automatically detects and configures the address of each intelligent pressure plate when powered on, and connects The position information of each intelligent platen is uploaded to the repeater; the repeater transmits the position information of each intelligent platen to the host computer through the network; the host computer is connected with the repeater to monitor the intelligent platen dropout status.

[0039] The bus network is SPI network, or IIC network, or TXD / RXD network, or LIN bus network, or CAN network, or M-BUS bus network, or Ethernet, or ProfiBus network, or field bus network. The upper computer is connected with a plurality of repeaters; the upper computer is ...

Embodiment 2

[0057] The difference between this embodiment and Embodiment 1 is that the intelligent pressing plate is as image 3 As shown, it includes handle 21 , panel 22 , bracket 23 , measuring circuit 24 , and sensing device 25 . The handle 21 is used to control the on-off of the main circuit of the intelligent platen; the panel 22 is located in the middle of the intelligent platen, and the handle 21 is fixed; the bracket 23 is connected to the handle 21 through the panel 22 ; The sensing device 25 is used to sense the on-off state of the handle 21; the measuring circuit 24 is used to receive the information sensed by the sensing device. A positioning post is provided in the middle of the bottom of the handle, and copper posts are provided at both ends of the positioning post. The panel 22 is a groove-shaped positioning panel, the middle of the groove-shaped positioning panel is provided with a positioning hole that fits with the positioning column, and the two ends of the groove-sha...

Abstract

The invention discloses an intelligent detection system and a detection method of press plate positions. The system comprises at least two intelligent press plates, a repeater and an upper computer, wherein all the intelligent press plates are connected in a cascaded mode and upload self position information to the repeater through a bus network; the repeater is connected with the upper computer in a network mode and used for transmitting the position information of all the intelligent press plates through a network; and the detection system is used for monitoring the real-time on-off states of the intelligent press plates and recording historical running data and can be further upgraded into an expert system for running the press plates. The invention solves the problem of position monitoring of control / tripping press plates of a relay protection system in a power system, realizes the automation of the monitoring of the press plate positions, can accurately reflect the positions of the press plates in real time and avoid error press plate on-off caused by artificial factors, eliminates safe accident hidden troubles caused by error press plate on-off, achieves scientific prevention before accidents and greatly improves the running safety of a power grid.

Description

technical field [0001] The invention belongs to the field of power system equipment, and relates to an intelligent detection system and a detection method for the position of a pressure plate of power control equipment. Background technique [0002] "Power production, safety first", the safe operation of the relay protection system is the most important security guarantee of the power system, and the safe operation of related equipment in the relay protection system is especially important. Due to the particularity of equipment such as relay protection devices, the "pressure plate" that must be designed on the trip circuit is an important means of ensuring the safe operation of the relay protection system and the safety of personnel. The pressure plate is a disconnection point visible to the naked eye, which is convenient for operators to judge whether the tripping / closing circuit of the relay protection device can be connected to the tripping / closing coil of the switch (cir...
