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, specially a kind of transforming plant protecting signal is wirelessly again
Return device.
Background technology
At present, transforming plant protecting signal distant place involution has two ways, and a kind of mode is monitoring backstage and protection observing and controlling dress
It is same producer to put manufacturer, and measure and control device possesses distant place slot signal function, and the two can be soft by ether net mode
Part protocol carrys out involution protection signal, and in fact, at least more than 80% supervisory control of substation backstage with protection supervisory equipment not
Same producer, though or belong to same producer's product, measure and control device does not possess distant place reset function；Another way is to pass through
Cable is laid between public observing and controlling screen and protection supervisory equipment to realize, cable investment cost is such a process increases, and is constructed
Loaded down with trivial details, the engineering time is long, and takes too many valuable remote control dry contact resource, method poor operability.
The content of the invention
The present invention is in order to solve the problems, such as that transforming plant protecting measure and control device is unable to the effective involution in a distant place, there is provided a kind of power transformation
Protection signal of standing is wireless re-setting device.
The present invention adopts the following technical scheme that realization：A kind of transforming plant protecting signal is wireless re-setting device, including
Master controller and receiving actuator, wherein master controller include the first Power Management Unit, the first MCU Main Processing Unit, an ISM
Frequency range Transmit Receive Unit, GSM/CDMA wireless data sending units, input/output interface unit, input/output interface unit and first
The input connection of MCU Main Processing Unit, the outfan of the first MCU Main Processing Unit and the first ISM band Transmit Receive Unit it is defeated
Enter end connection, the input of the first MCU Main Processing Unit and GSM/CDMA wireless data sendings unit connect, and the first Power Management Unit is
First MCU Main Processing Unit, the first ISM band Transmit Receive Unit and GSM/CDMA wireless data sending units are powered；Receiving actuator
Including second source administrative unit, the second MCU Main Processing Unit, the second ISM band Transmit Receive Unit and exit relay unit,
The outfan of the second ISM band Transmit Receive Unit and the input connection of the second MCU Main Processing Unit, the second MCU Main Processing Unit
Outfan and exit relay unit control end connection, second source administrative unit be the second MCU Main Processing Unit, second
ISM band Transmit Receive Unit and exit relay unit are powered.
When using, the input-output unit of master controller is connected with the remote control dry contact of the public observing and controlling screen of transformer station, receives
The exit relay unit of executor is simultaneously connected in protection supervisory equipment signal return loop, remote monitoring center or transformer station
Distant place involution instruction is issued in situ by background monitoring machine, distant place involution is instructed is transmitted by the remote control dry contact of public observing and controlling screen
Input-output unit to master controller issues distant place involution instruction, the MCU in master controller by SMS
Main control unit after the instruction sent is collected, by analytical calculation and coding pass to the first ISM band Transmit Receive Unit,
First ISM band Transmit Receive Unit carries out packing transmitting after instruction is received to data, the 2nd ISM frequencies in receiving actuator
Section Transmit Receive Unit receives the instruction of the first ISM band Transmit Receive Unit and passes to the second MCU Main Processing Unit, and second
MCU Main Processing Unit controls exit relay unit action, and the circuit for making and being connected in protection supervisory equipment signal return loop connects
It is logical several seconds, so as to protection supervisory equipment signal return.
In order to overcome existing transformer station's distant signal involution mode difficulty of construction big, poor operability is proposed the present invention
A kind of re-setting device, the remote control dry contact control master controller that the re-setting device passes through public observing and controlling screen, or it is short by mobile phone
Letter control master controller, master controller is wirelessly communicated with the receiving actuator on protection supervisory equipment, sent out
Instruction is sent to connect reset circuit, so that the signal return of protection supervisory equipment.
