Embodiment 1

[0019] The staff conducts substation inspections. When approaching the outdoor equipment partition fence, the microwave radar module of the intelligent sensing voice broadcaster of the equipment status installed at the opening of the fence detects the presence of objects that meet the warning height through its own microwave radar. Close, according to the operating characteristics and equipment conditions, the switch sensing module of each knife switch interface senses that the circuit breaker is in the open position and the isolation knife on both sides is still closed, and the status value of each switch is detected. Output to the controller, and the controller combines the status values ​​to finally conclude that the current device is in the "hot standby state".

[0020] In the hot standby state, routine maintenance operations are not allowed on the line. This is because the line may resume power transmission at any time. If the routine maintenance operations are carried out, t...

Embodiment 2

[0023] The staff conducts substation inspections. When approaching the outdoor equipment partition fence, the Weibo radar module of the intelligent sensing voice broadcaster of the equipment status installed at the opening of the fence can detect objects that meet the warning height through its own microwave radar. Close, according to the operating characteristics and equipment conditions, through the switch sensing module of each knife switch interface, the current line will be sensed by the circuit breaker and the isolation knives on both sides are in the open state at the same time, both sides of the circuit breaker (moving and static contacts) There is no voltage, and one side of the line is connected to the earth through a grounding switch or a three-phase short-circuit grounding wire.

[0024] In this state, grounding wires are hung on both ends of the working point, and the first and second work tickets and corresponding safety measures can be used to ensure safe operation ...

Embodiment 3

[0027] On the basis of the original technical solution, the microwave radar module is used to detect the object at different times of returning to the microwave to obtain the actual distance change of the current human body from the device. When the distance of the staff is 1 meter, the microwave radar module transmits the distance value to the controller , The controller outputs to the audio codec module, the audio codec module converts the voice code into the corresponding voice signal and outputs it to the speaker. The audio device uses its own components to broadcast the voice signal in the form of sound, and broadcasts "Current Distance Device 1 Meter".

[0028] In order to prevent accidentally touching the corresponding dangerous devices when the staff is working, install the microwave radar module in the corresponding position to avoid accidental touching.

[0029] The serial numbers in the above embodiments are only for description, and do not represent the sequence of the ...

Abstract

The invention provides an intelligent sensing voice broadcaster for equipment states, and belongs to the field of power transformation equipment. A controller is connected with a proximity detection module, a switch sensing module and an audio encoding and decoding module to realize processing and storage of signals of each module; the switch sensing module is connected to a knife switch of equipment, and the state change of the knife switch of each component is detected to realize accurate control of the working state of each component of the equipment, and the cold and hot standby states areeffectively identified; and after the controller receives that the proximity detection module detects that a human body approaches, the working state in a memory is called for encoding and decoding,the encoded and decoded working state is output to the audio encoding and decoding module, the encoded and decoded working state is converted into an audio signal, and the audio signal is output to asound box, so that an effective warning effect is achieved.

Description

Technical field [0001] The invention belongs to the field of substation equipment, and particularly relates to an intelligent induction voice broadcaster for equipment status. Background technique [0002] The substation equipment currently has various equipment states such as operation, hot standby, cold standby, switch overhaul, line overhaul, switch and line overhaul. In actual work, substation maintenance staff need to open the fence corresponding to the working interval before entering and carrying out Related work. In recent years, accidents such as electric shocks and forced power outages of equipment have often occurred due to personnel entering the electrified interval when working in substations. How to prevent such accidents from happening is a key research topic. [0003] At present, sensors such as vibration sensors, infrared detection sensors, image and temperature sensors are mainly used to perceive the working status of different components of substation equipment....
