Description
Technical Field
The invention belongs to the field of power transformation equipment, and particularly relates to an intelligent sensing voice broadcaster for equipment state.
Background
At present, multiple equipment states such as operation, hot standby, cold standby, switch maintenance, line maintenance, switch and line maintenance exist in the substation equipment, and the fence corresponding to the work interval needs to be opened by a substation maintenance worker in the actual work so as to enter and carry out related work. In recent years, accidents such as electric shock and forced power failure of equipment often occur due to the fact that personnel mistakenly enter an electrified interval when a transformer substation works, and how to prevent the accidents from occurring is a relatively critical research subject.
At present, sensors such as a vibration sensor, an infrared detection sensor, an image sensor, a temperature sensor and the like are mainly adopted to sense the working states of different parts of substation equipment. However, there are many disadvantages, for example, when the apparatus is in a cold standby state, the disconnector and the circuit breaker are both in the open position, and when the disconnector and the circuit breaker are closed, the apparatus is switched to the operating state. When the device is in a hot standby state, only the circuit breaker is in the open position, at which time the closing switch device switches to the operating state. When the equipment is in a maintenance state, the disconnecting switch and the circuit breaker are located at a tripping position.
If the state of the corresponding knife switch is not detected, the state of the current substation equipment cannot be accurately acquired. Currently, products are available that lack device status detection related to switch status.

The technical scheme provided by the invention has the beneficial effects that: the switch sensing modules are connected to the knife switch, and the switch state is quantized into the state value and transmitted to the controller, so that the current running state of each part of the equipment can be directly quantized into the numerical value and stored in the controller; compared with a high-voltage environment, the knife switch is provided with the sensor, the interference on the sensor erected in each circuit is less, and the accuracy is higher; the microwave radar module detects that personnel are close to, and the controller is reported through the stereo set, reaches the purpose of noticing safety when reminding the staff operation.
Drawings
In order to more clearly illustrate the technical solution of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on the drawings without creative efforts.
FIG. 1 is a system block diagram of the present invention.
Detailed Description
To make the structure and advantages of the present invention clearer, the structure of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the system comprises a controller, a switch sensing module and an approach detection module, wherein the switch sensing module is connected to each knife switch of the substation equipment, and outputs a signal to the controller by sensing the switch closing state of the knife switch, and the controller records the current state of each knife switch and stores the current state in a memory of the controller after receiving the output signal of each switch sensing module.
The microwave radar module achieves the purpose of approaching detection by perceiving whether an object moves in the limited range. Through modulation on the microwave radar module, the detection range is limited to the movement of an object with the height of a human body being more than 140cm, so that the false alarm caused by the detection of the approach of an animal at ordinary times is reduced.
Example one
The staff carries out the substation and patrols, when being close to and install at outdoor equipment interval rail, install the microwave radar module of the equipment state intelligence response voice broadcast ware at the rail opening part, the microwave radar perception of self has the object of the height of reporting an emergency and asking for help or increased vigilance to be close to, will be according to the operating characteristic and the equipment condition, the circuit breaker appears in the current circuit of switch perception module perception through each knife switch interface and is in the open position, both sides are kept apart the still closed state of knife, export the state value of each switch detection module to the controller, the controller combines each state value to reachd current equipment at last and is in "hot stand-by state".
In the hot standby state, normal maintenance operation is not allowed on the line, because the line can recover power transmission at any time, and if the normal maintenance operation is performed, there is a great risk. In the rules of work for electrical safety, item 1.8, the term "electrical equipment in operation" is understood to mean electrical equipment which is wholly, partially or once operated. Therefore, the staff hear the intelligent broadcasting, stop entering the electrified compartment promptly, avoided accident or casualty incident that from this leads to, ensured power workers' safety work.
Therefore, the voice codes of the hot standby state are output to the audio coding and decoding module, the audio coding and decoding module outputs corresponding voice signals to the sound box through converting the voice codes, the sound equipment externally emits the voice signals in a voice mode through the components of the sound equipment, and the broadcasting state is the hot standby state.
Example two
The staff carries out the substation and patrols, when being close to and installing at outdoor equipment interval rail, install the microblog radar module of the device state intelligence response voice broadcast ware at the rail opening part, the microwave radar perception through self has the object that accords with the height of reporting an emergency and asking for help or increased vigilance to be close to, will be according to the operating characteristic and the equipment condition, circuit breaker and both sides isolation switch blade are in the off-state simultaneously in the current circuit of switch perception module perception through each knife switch interface, circuit breaker both sides (sound contact) all do not have the voltage, and the state of circuit one side through ground connection knife switch or three-phase short circuit earth and ground intercommunication.
In this state, the grounding wires are hung at two ends of the working point, and the first and second working tickets and corresponding safety measures are used to ensure the safe operation in the construction.
Therefore, the voice codes in the hot standby state are output to the audio coding and decoding module, the audio coding and decoding module outputs corresponding voice signals to the sound box through converting the voice codes, the sound equipment externally emits the voice signals in a voice mode through components of the sound equipment, and the broadcasting state is in a maintenance state.
