Wireless electric-controlled lock and its control method

Abstract

The invention provides a wireless electrically controlled lock and the controlling method thereof. The electrically controlled lock is provided with the functions of status signal feedback, locking logic control and transmits the lock status and the control commands through operational prompting. The wireless electrically controlled lock has the advantages that the mis-operation is not easy to occur, and the security performance is high. The wireless electric controlled lock and the controlling method thereof adopts the technical proposal that a wireless electric controlled lock which comprises a lock body, a lock pin, an electric controlled element and a control circuit is adopted; a concave cavity used for positioning the electric controlled element and the control circuit and a communicating groove through which the lock pin can be ensured to vertically move are arranged on the lock body, a wireless receiving and transmitting circuit and a wireless receiving and transmitting antenna which can communicate data with an external controller are arranged on the control circuit, and the wireless receiving and transmitting circuit and the rest parts of the control circuit are electrically connected and jointly arranged in the casing body of the wireless electric controlled lock.

Description

technical field [0001] The invention relates to a radio-controlled lock and its control method, in particular to an electric-controlled lock with wireless communication function and its control method, which are used in a power system to prevent electrical misoperation and lock running equipment. Background technique [0002] The "five-prevention" locking system of electric power is a control system for my country's power system to prevent misoperation of switching during power transmission and transformation in power plants and substations. Prevent the knife switch from being pulled and closed with load, prevent the live wire from being connected to the ground wire, and prevent the switch from being closed with the ground wire. Over the years, switching misoperation has repeatedly caused serious accidents in the power system, so preventing switching misoperation accidents is one of the keys to the safety of power transmission and transformation. At present, most of the oper...

AI Technical Summary

Problems solved by technology

At present, most of the operating mechanisms such as substation ground piles, net doors and knife gates are locked in the form of "five-proof" padlocks, and some even have no locking mechanism and are directly operated manually.

This method of manual operation, although it is controlled by logic devices such as computer keys, is still prone to misoperation due to human factors, especially in the process of emergency unlocking, because the logic control process of the device is released, it is completely controlled by the user. Manual judgment is more prone to misoperation accidents caused by human factors

At the same time, since there is no feedback signal of the locking state, the on-site operation situation cannot be fed back in real time, so that the operators in the main control room cannot understand the operation status of the on-site operation equipment, and cannot control the operation sequence of the on-site operation equipment

[0003] With the improvement and development of technology, some locking components adopt electronically controlled locks, but the currently used electronically controlled locks are all using wired control, that is, using cables to transmit the status signals of electronically controlled locks and the control signals for unlocking and locking. The installation and maintenance are more complicated, it is necessary to lay pipelines or bury cables, the cost is high, and there are certain difficulties in the reconstruction of old stations, especially for some places where it is difficult to lay cables, it is more difficult to install electric control locks

For example, although the design scheme of "an electric control lock" with the patent number "200420102291.7" can solve the problem of real-time control, it needs to lay cables on site due to the use of wired connections, and for electrical equipment in special installation locations, due to Unable to install cables and give up the use of electric locks, making real-time locking incomplete

[0004] Therefore, the existing similar products have the following disadvantages: cables need to be laid on site, which increases the construction cost. Since the cables are used outdoors and between non-tightly protected equipment, they are easily damaged by animals such as mice, as well as damage such as aging and interference, which increases the cost of construction. Maintenance workload, the special installation position cannot lay cables and cannot use electric control locks, and cannot meet the complete locking requirements
