Abstract
The invention relates to a resetting device for a protection and monitoring apparatus of a transformer station, specifically a device for the wireless resetting of a protection signal of the transformer station. The device comprises a main controller and a receiving executor. The main controller comprises a first power management unit, a first MCU main control unit, a first ISM frequency-band radio-frequency receiving and transmitting unit, a GSM/CDMA wireless data transmission unit, and an input/output interface unit. The receiving executor comprises a second power management unit, a second MCU main control unit, a second ISM frequency-band radio-frequency receiving and transmitting unit, and an exit relay unit. In order to solve the problems that the construction of a remote signal resetting mode of a conventional transformer station is difficult and the maneuverability is low, the invention proposes the resetting device. The resetting device controls the main controller through a remote control dry contact of a public measurement and control screen, and the main controller communicates with the receiving executor disposed on the protection and monitoring apparatus in a wireless mode and transmits an instruction to enable a reset circuit to be connected, thereby enabling achieving the resetting of a signal of the protection and monitoring apparatus.
Description
Technical field
The present invention relates to the re-setting device of transforming plant protecting measure and control device, be specially a kind of transforming plant protecting signal wireless re-setting device.
Background technology
At present, the distant place involution of transforming plant protecting signal has two kinds of modes, a kind of mode is monitoring backstage and protection supervisory equipment manufacturer is same producer, and measure and control device possesses distant place slot signal function, the two can carry out involution guard signal by the communication of Ethernet mode software protocol, and in fact, more than at least 80% supervisory control of substation backstage and protection supervisory equipment are not same producers, though or belonging to same producer product, measure and control device does not possess distant place reset function; Another kind of mode is realized by cable laying between public observing and controlling screen and protection supervisory equipment, and such a process increases cable investment cost, construct loaded down with trivial details, the engineering time is long, and take too many valuable remote control dry contact resource, method poor operability.
Summary of the invention
The present invention can not the problem of the effective involution in a distant place in order to solve transforming plant protecting measure and control device, provides a kind of transforming plant protecting signal wireless re-setting device.
The present invention adopts following technical scheme to realize: a kind of transforming plant protecting signal wireless re-setting device, comprise master controller and receiving actuator, wherein master controller comprises the first Power Management Unit, first MCU Main Processing Unit, first ISM band Transmit Receive Unit, GSM/CDMA wireless data sending unit, input/output interface unit, input/output interface unit is connected with the input of the first MCU Main Processing Unit, the output of the first MCU Main Processing Unit is connected with the input of the first ISM band Transmit Receive Unit, the input of the first MCU Main Processing Unit is connected with GSM/CDMA wireless data sending unit, first Power Management Unit is the first MCU Main Processing Unit, first ISM band Transmit Receive Unit and GSM/CDMA wireless data sending unit are powered, receiving actuator comprises second source administrative unit, the second MCU Main Processing Unit, the second ISM band Transmit Receive Unit and exit relay unit, the output of the second ISM band Transmit Receive Unit is connected with the input of the second MCU Main Processing Unit, the output of the second MCU Main Processing Unit is connected with the control end of exit relay unit, and second source administrative unit is the second MCU Main Processing Unit, the second ISM band Transmit Receive Unit and exit relay unit are powered.
During use, the remote control dry contact that the input-output unit of master controller and transformer station public observing and controlling are shielded is connected, the exit relay unit of receiving actuator is also connected in protection supervisory equipment signal return loop, remote monitoring center or transformer station issue distant place involution instruction by background monitoring machine on the spot, distant place involution instruction passes to the input-output unit of master controller by the remote control dry contact that public observing and controlling is shielded or issues distant place involution instruction by SMS, the first MCU Main Processing Unit in master controller is after collecting the instruction sent here, also encoded by analytical calculation and pass to the first ISM band Transmit Receive Unit, first ISM band Transmit Receive Unit carries out packing to data and launches after receiving instruction, the second ISM band Transmit Receive Unit in receiving actuator receives the instruction of the first ISM band Transmit Receive Unit and passes to the second MCU Main Processing Unit, second MCU Main Processing Unit controls the action of exit relay unit, make and be connected in the circuit ON several seconds in protection supervisory equipment signal return loop, thus protection supervisory equipment signal return.
The present invention is large in order to overcome existing transformer station distant signal involution mode difficulty of construction; poor operability; a kind of re-setting device is proposed; the remote control dry contact control master controller that this re-setting device is shielded by public observing and controlling; or control master controller by SMS; master controller wirelessly with the receiving actuator communication be arranged on protection supervisory equipment, send instruction and reset circuit connected, thus make the signal return of protection supervisory equipment.
