Encrypted authorized automatic remote control opening and closing device and its operation method

Abstract

The invention discloses an encryption authorization type automatic remote control starting and shutdown device. The encryption authorization type automatic remote control starting and shutdown device comprises a starting and shutdown device body and a remote control emitter, wherein the starting and shutdown device body is usually connected to a power supply circuit in series, the remote control emitter can be carried with an operator, the remote control emitter has control over the starting and shutdown device body, and the starting and shutdown device is used for achieving starting and shutdown of a power supply unit. The invention further discloses an operation method of the encryption authorization type automatic remote control starting and shutdown device. According to the operation method of the encryption authorization type automatic remote control starting and shutdown device, the purpose that a plurality of remote control emitters have the authorization of operation of the starting and shutdown device body can be achieved, and it is ensured that only one remote control emitter has the right to carry out operation in the process of operation. According to the encryption authorization type automatic remote control starting and shutdown device and the operation method of the encryption authorization type automatic remote control starting and shutdown device, starting and shutdown of the power supply unit are controlled through convenient authorization, it is ensured that the power supply unit carries out reliable power supply or outage, and personal safety and property safety are ensured.

Description

technical field [0001] The invention relates to the field of maintenance and repair of industrial power supply electrical equipment, in particular to an encryption-authorized automatic remote control switch device. Background technique [0002] In the industrial power supply system, the power must be cut off when the equipment is repaired and overhauled. In existing industrial sites, in order to ensure power failure, four methods are usually adopted for power supply equipment: placing warning signs, adding mechanical locks, combination locks, or on-site guarding by personnel. [0003] 1. There are three kinds of problems when placing warning signs: [0004] (1) The maintenance personnel forgot to remove the warning sign after debugging the equipment, which made the equipment unable to supply power normally; [0005] (2) If the warning sign is made too small, the warning effect is not obvious, and there is a possibility of wrong power transmission, which endangers the safet...

AI Technical Summary

Problems solved by technology

[0004] (1) The maintenance personnel forgot to remove the warning sign after debugging the equipment, which made the equipment unable to supply power normally;

[0005] (2) If the warning sign is made too small, the warning effect is not obvious, and there is a possibility of wrong power transmission, which endangers the safety of maintenance personnel; if the warning sign is too large, it is inconvenient for maintenance personnel to carry it;

[0006] (3) The safety awareness of other personnel is not strong, ignoring the warning of the warning sign, sending electricity at will, posing a threat to the personal safety of the maintenance personnel

[0008] (1) There are various forms of power supply equipment, and it is not convenient to add mechanical locks;

[0009] (2) The industrial site environment is harsh, and the mechanical lock is easy to corrode;

[0010] (3) The mechanical lock can only be opened or closed by the corresponding key, and maintenance personnel need to carry multiple keys, and it is not easy to distinguish the corresponding lock and key

[0012] (1) In industrial sites, multiple maintenance personnel often have the right to control the power transmission or power-off of a single power supply equipment. Most of these personnel must know the password of the lock, and it is impossible for these personnel to know whether the equipment is in the maintenance state. There may be a possibility of wrong power transmission, which will pose a threat to personnel safety;

[0013] (2) A single maintenance person often has the right to control multiple power supply equipment to power on or off, so he must remember the respective passwords of the power supply equipment, which is very difficult;

[0014] (3) Once the password of the password lock on the device is changed by others, other personnel cannot operate it

[0015] The existing central lock in the market can also be used for encrypted power supply equipment, but the lock and remote control of the central lock are controlled in a one-to-one manner, which is not suitable for one-to-many and many-to-many control modes in industrial sites

[0016] (4) Using on-site personnel to take care of the staff will increase the number of personnel, resulting in a waste of manpower
