Embodiment Construction

[0018] Such as figure 1 As shown, a system for preventing misoperation of electrical equipment, which includes a system host of the error prevention system and at least one work card for storing identity information, the host computer of the error prevention system communicates with a plurality of identification devices, and the host computer of the error prevention system Control and connect multiple on-site intelligent locks; the on-site intelligent locks are set in one-to-one correspondence with the identification device, and the work card communicates with the host of the anti-mistake system and the identification device (that is, the host of the anti-mistake system and the identification device can obtain the identity from the work card information).

[0019] The host of the anti-mistake system stores the one-to-one relationship information and operation rules between the on-site intelligent lock and the identification device (in the actual application of the applicant, t...

Abstract

The invention particularly relates to a system and a method for preventing electric equipment from incorrect operation. The system comprises an error prevention system main engine and at least one working card for storing identity information, wherein the error prevention system main engine is in communication connection with identity recognition devices; the error prevention system main engine is in control connection with a plurality of field intelligent locksets; the field intelligent locksets and the identity recognition devices are arranged in one-to-one corresponding; the working card is in communication match with the error prevention system main engine and the identity recognition devices. The system and the method can prevent wrong operators from operating or operating in a wrong job site, so that the incorrect operation of the electric equipment can be effectively prevented and an electric power accident caused by the incorrect operation is avoided.

Description

【Technical field】 [0001] The invention relates to a system and method for preventing misoperation of electrical equipment in power plants and substations. 【Background technique】 [0002] According to the requirements of power industry management, operating equipment in power plants and substations, such as circuit breakers, isolating switches, ground wires, ground knives, net doors, etc., must be locked to prevent equipment and personnel casualties due to misoperation . The previous locking technology mainly used mechanical and electrical logic locking principles. For example, household padlocks, electromagnetic locks, and mechanical locks with partial logical relations were used on the operating mechanism of the operating equipment. Although these methods can prevent some misoperations from occurring, But there are also many problems, mainly in: manual judgment, there is a possibility of misjudgment and operation error, at the same time, mechanical corrosion, installation ...
