Intelligent terminal for substation operation and inspection

Abstract

The invention provides an intelligent terminal for substation operation and inspection, which belongs to the power system. The intelligent terminal for substation operation and inspection comprises a processing circuit formed by a processor and a memory circuit connected with the processor. The periphery of the processing circuit is connected with a communication circuit and a GPS module circuit; the processing circuit is provided with an instruction input and output interface; an audio key circuit and an image acquisition module are connected onto the instruction input interface; a voice alarming circuit is arranged on the instruction output interface; the processing circuit is also provided with a power supply interface; a charging and discharging circuit and a battery are connected onto the power supply interface; and a liquid crystal display circuit is also connected onto the intelligent terminal. Real-time control and security response towards the inspection content can be realized by using the intelligent terminal, standardization and programming of behaviors of an operation and maintenance person can be realized, electronic monitoring on a monitoring person is realized, happening of electrical misoperation accidents is prevented, the personal safety, the power grid safety and the device safety are ensured, and the misoperation generation rate is reduced.

Description

technical field [0001] The invention belongs to the field of power systems, in particular to an intelligent terminal used for substation operation and inspection. Background technique [0002] In recent years, power accidents have occurred frequently all over the country. Due to the high risk of high-voltage electricity and its importance to industry, these accidents often cause non-serious consequences, which not only endanger the lives and property of people in the power industry and surrounding areas, but also endanger the country's economic development. Of course, the reasons for frequent electrical accidents include: [0003] First, there are defects in the current microcomputer five-proof device: ① Only one-time logic judgment is made before operation, and the logic cannot be judged in real time, and it is impossible to know whether some equipment has changed state during the operation. ②5. It is impossible to display the throw-in and withdrawal of the secondary pres...

AI Technical Summary

Problems solved by technology

[0003] First, there are defects in the current microcomputer five-proof device: ① only one-time logic judgment is made before operation, and the logic cannot be judged in real time, and there is no way to know whether some equipment has a state change during the operation

②5. It is impossible to display the throw-in and withdrawal of the secondary pressure plate. It is necessary to manually check the secondary pressure plate on site, and it is impossible to prevent the misoperation of the secondary pressure plate.

Second, in the switching operation, it is often caused by the use of paper operation tickets: in rainy days, it is easy to be wet and damaged; when operating at night, there is currently no special lighting for paper operation tickets, which will affect the switching operation

In addition, it also includes: in the switching operation, often due to reasons such as personnel fatigue, the wrong interval occurs, or the repetition error occurs. After each operation is completed, a "√" mark is not made in time, resulting in missing items or skipping operations. lead to misuse accidents
