Description
Technical Field
The invention belongs to the field of power transformation equipment, and particularly relates to an equipment state sensing voice broadcaster.
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 current state of the transformer substation equipment cannot be accurately acquired; and long wires are still needed to transmit data after relatively distant switches in the substation equipment are provided with sensors. At present, complete upgrading of substation equipment in the market consumes too much unrealistic, and the sensing condition of the sensor is additionally installed, so that potential safety hazards exist due to too long wires. Currently, products are available that lack device status detection related to switch status.

The NBIOT communication module is divided into a main NBIOT communication module and a plurality of slave NBIOT communication modules, and the slave NBIOT communication modules are installed in each transformer substation device, so that state data of the knife switch of each transformer substation device far away from the controller can be acquired.
Avoided because substation equipment erects in advance, after the interim upgrading rebuild has intelligent speech state to report the function, the connecting wire of overlength spanes each part and has the potential safety hazard, realizes the interconnection with the controller with the switch perception module of remote position through following NBIOT communication module. And the controller and the cloud platform are connected through the main NBIOT communication module, and the state data of each knife switch is uploaded.
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
