[0015] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:
[0016] Example: Figure 1 and Figure 2 As shown, the industrial fan intelligent control device for a rail transit vehicle base in this embodiment includes a centralized control main station, a centralized control substation, a temperature sensor, a ZigBee gateway, a ZigBee wireless receiving unit, a frequency converter, a frequency converter input resistor, and an industrial fan body.
[0017] Specifically, the centralized control master station and ZigBee gateway are installed in the vehicle base control room. The wireless receiving unit, frequency converter, and frequency conversion input resistor are installed in the centralized control substation. The temperature sensor communicates with the centralized control master station through the local area network, and transmits the actual temperature value of the vehicle base to the centralized control master station in real time. When the staff receives the vehicle maintenance task in the vehicle base control room, the on-site temperature target value is set through the centralized control master station, and the centralized control master station transmits the required temperature adjustment range to the ZigBee gateway through the local area network; the ZigBee gateway transmits the temperature adjustment signal to the ZigBee wireless receiving unit in the centralized control substation through the ZigBee wireless link channel. After receiving the adjustment signal, the ZigBee wireless receiving unit changes the output of the frequency converter by adjusting the resistance value of the frequency conversion resistor, thereby changing the output frequency of the centralized control substation, and then adjusting the speed of the industrial fan, so that the vehicle base can centrally adjust the speed of all industrial fans according to the on-site temperature, and then remotely adjust the temperature of the vehicle base maintenance site in real time to meet the use needs of the maintenance staff.
