Methods for regulating air conditioning temperature of subways in smart cities and internet of things systems thereof

A method for regulating air conditioning temperature of a subway in a smart city, comprising:

• obtaining, based on at least one collecting device, temperature data and humidity data inside and outside a carriage of a plurality of carriages of the subway, the at least one collecting device including at least one of an infrared temperature sensor, a gas temperature sensor, a radiation temperature sensor, a hair hygrometer, a dry and wet bulb hygrometer, a dew point hygrometer, a coulomb hygrometer, and a temperature and humidity meter;
• wherein the at least one collecting device includes at least two first collecting devices and at least two second collecting devices, the at least two first collecting devices are installed at a first preset position inside the carriage, and a distance between two adjacent first collecting devices satisfies a first preset condition;
• and the at least two second collecting devices are installed at a second preset position within a platform, and a distance between two adjacent second collecting devices satisfies a second preset condition;
• determining, based on the temperature data and the humidity data, refrigeration power adjustment values and ventilation adjustment values of the plurality of carriages;
• generating a control instruction for controlling a temperature regulation device and a ventilation device based on the refrigeration power adjustment values and the ventilation adjustment values of the plurality of carriages, the temperature regulating device including an air conditioner, a refrigerator, and a heater, the ventilation device including a device that directly regulates humidity and a device that indirectly regulates the humidity, the device that directly regulates the humidity including a humidifier and a dehumidifier, the device that indirectly regulates the humidity including an exhaust fan, the control instruction referring to an instruction for controlling an adjustment of a refrigeration power of a subway air conditioner and/or a ventilation of the ventilation device, the control instruction including the refrigeration power adjustment values and the ventilation adjustment values;
• controlling the temperature regulation device based on the control instruction to regulate temperature of the plurality of carriages, including:
• adjusting current operating power of the temperature regulation device to target operating power according to a corresponding refrigeration power adjustment value of the temperature regulation device;
• and
• controlling the ventilation device based on the control instruction to regulate humidity of the plurality of carriages, including:
• adjusting current operating power of the ventilation device to target operating power of the ventilation device according to a corresponding ventilation adjustment value.
