Problems solved by technology

The current situation is: 1. When the universal key operation is used routinely, the person in charge is relatively far away from the substation. From the application to the on-site verification and signature, it takes at least one hour and at most two hours.
2. After the centralized control of the substation is implemented, one main station centrally controls multiple sub-stations. If multiple sub-stations are operated at the same time, they need to be unlocked, and the person in charge is helpless
In order to solve the arbitrariness and lack of management of the unsealing of the five-proof unlocking key in the existing substation management, and reduce the problem of accidents caused by illegal operations, the utility model provides a five-proof unlocking key management device for the substation, using advanced two-dimensional codes and computers Control technology greatly enhances the security of the use of the five-proof unlocking key, ensuring the normal operation of the entire power grid

Embodiment 1

[0029] Embodiment 1, the present invention provides an intelligent five-proof operation universal key management device, including a master control module 1 and a field module 5. The communication module 3 of communication, described field module 5 comprises the box body that places universal key, the electromagnetic lock 9 that is arranged on the box body, is used for the power adapter module 7 that supplies power to electromagnetic lock 9, controls the control of electromagnetic lock 9 Module 6 and the signal transceiving module 4 for receiving control instructions. The person in charge of the universal key manages the master control module. When the master key needs to be used, the command is issued through the control terminal of the master control module, and the communication module sends the command. After receiving the command, the signal transceiver module of the field module transmits the command To the control module, the control module controls the opening of the e...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is:

[0035] The input end of the power adapter module 7 is connected to the battery or the mains line, the output end of the power adapter module 7 is connected to the control module 6 and the relay 8, the control module 6 is connected to the relay 8, and the relay 8 is connected to the relay 8. The electromagnetic lock 9 is connected, and the signal transceiving module 4 is connected with the control module 6 .

[0036] This is a connection method for the control module to control the electromagnetic lock. The relay is used as the switch mechanism, and the power adapter module supplies power to the microcontroller and the electromagnetic lock. In general, converting the mains power to the microcontroller and the electromagnetic lock can With the voltage and current used, the control module can control the relay to control the shutdown between the electromagnetic lock and the power adapter module, thereby controll...

Embodiment 3

[0038] The difference between this embodiment and Embodiment 1 is:

[0039] The box body includes a main body 21 and an opening and closing door 10 arranged on the side, and the electromagnetic lock 9 includes an action mechanism arranged on one side of the opening and closing door 10 and a suction mechanism arranged on the main body 21 to cooperate with the action mechanism;

[0040] The action mechanism includes a first cavity 16 arranged on one side of the switch door 10, a guide hole 11 is arranged on the left side of the first cavity 16, and a guide rod 12 and a limiting cavity 13 are arranged in the guide hole 11. A limiting plate 14 is set in the limiting cavity 13 on the guide rod 12, a reset mechanism is set in the limiting cavity 13, a sliding lock body 17 is arranged on the right side of the guiding rod 12, and the sliding lock body The right side of 17 is provided with dead bolt 18;

[0041] The suction mechanism includes a second cavity 22 arranged on the main bo...
