Embodiment 1

[0017] Embodiment 1: The ventilator self-adaptive intelligent control system is composed of three parts such as a mine environment parameter monitoring unit, a signal transmission network and a motor control unit. The mine environment parameter monitoring unit is connected to the input end of the signal transmission network, and the output end of the signal transmission network It is connected with the motor control unit, and the output terminal of the motor control unit is connected with the fan;

[0018] The mine environment parameter monitoring unit includes a gas dynamic monitoring sensor, a gas concentration sensor, a wind speed sensor, a carbon monoxide sensor, an oxygen sensor and an ambient temperature sensor;

[0019] The signal transmission network can have multiple methods, including wireless transmission, CAN bus transmission and industrial Ethernet transmission, and can also combine multiple communication networks to complete wired and wireless transmission; the si...

Embodiment 2

[0030] Example 2: In figure 2 Among them, the gas dynamic monitoring sensor, gas concentration sensor, wind speed sensor, carbon monoxide sensor, oxygen sensor and ambient temperature sensor in the mine environmental parameter monitoring unit in the ventilator adaptive intelligent control system directly transmit the environmental monitoring signal to It is transmitted to the fan motor controller, and the fan motor controller outputs frequency modulation power supply to the fan motor, controls the speed of the fan, and adjusts reasonable ventilation parameters. Others are the same as in Example 1.

Embodiment 3

[0031] Example 3, in image 3 Among them, the gas dynamic monitoring sensor, gas concentration sensor, wind speed sensor, carbon monoxide sensor, oxygen sensor and ambient temperature sensor in the mine environmental parameter monitoring unit in the ventilator adaptive intelligent control system transmit the environmental monitoring signal through CAN bus communication. To the gateway, the monitoring signal is transmitted to the industrial Ethernet through the gateway, and then the signal is transmitted to the fan motor controller through the industrial Ethernet. The fan motor controller outputs frequency modulation power supply to the fan motor, controls the speed of the fan, and adjusts reasonably ventilation parameters. Others are the same as in Example 1.

The self-adaptive intelligent control system comprises a mine environment parameter monitoring unit, a signal transmission network and a motor control unit, wherein the mine environment parameter monitoring unit comprises a gas dynamic monitoring sensor, a gas concentration sensor, a wind speed sensor, a carbon monoxide sensor, an oxygen sensor and an environment temperature sensor; the signal transmission network comprises a CAN bus, a wireless communication network or an optical fiber industrial Ethernet; the motor control unit mainly comprises a frequency adjustment controller; the mine environment parameter monitoring unit is used for transmitting mine gas dynamic change, gas concentration, wind speed, carbon monoxide, oxygen and the mine environment information provided by the environment temperature sensor to the ventilator motor control unit via the communication network; the motor control unit is used for adjusting the frequency according to the mine environment parameters, controlling the rotation speed of the ventilator motor, providing reasonable wind flow, ensuring the safety of mine operation environment and simultaneously achieving the energy conservation effect of the motor.

Description

technical field [0001] The invention relates to an intelligent motor speed regulation system of a coal mine ventilator, in particular to an adaptive intelligent control system of a ventilator. Background technique [0002] Coal mine ventilator is the key equipment to ensure safe mining. The most important disaster that causes mass casualties and casualties in coal mine disasters is gas explosion. The ventilator is to dilute and discharge underground gas and ensure that underground workers have a sufficient amount of air that meets the requirements. . At present, most of the main ventilators in coal mines are driven by synchronous motors and run at a constant speed. Most of the ventilator speed control researched is program control from an electrical point of view. There are also some studies on fuzzy control, but they have not been used well. In reality, it cannot be put into practical application. Therefore, the current operation of the ventilator cannot guarantee that th...
