For example, the temperature and humidity sensor unit 5 has a window at an appropriate position corresponding to the shell to be exposed to the ambient air and contact the ambient air to detect the temperature and humidity values. The actual ambient temperature and humidity parameters detected by the temperature and humidity sensor unit 5 are encoded into data frames by the main control MCU unit 3 and then transmitted to the fixed control terminal b through the wireless communication unit 1 to complete the automatic temperature and humidity adjustment and control operations. The power management unit 14 provides working power for the charging mobile information collection terminal a.

[0023] The human-computer interaction unit 27 is used for inputting and displaying local control commands and data, so that when the charging mobile information collection terminal a is low on power or far away from the controllable range, the ambient temperature and humidity data collected by the temperature and humidity sensor unit 210 of the local fixed control terminal b can be combined to ensure that the system can still operate normally.

[0024] The charging mobile information collection terminal a and the fixed control terminal b are connected by wireless signal transmission. An electrical contact 17 is fixed on the charging mobile information collection terminal a, and an electrical contact 29 matching the electrical contact 17 is fixed on the fixed control terminal b. When the charging mobile information collection terminal a needs to be charged, the electrical contact 17 is connected to the electrical contact 29 of the fixed control terminal b, and the fixed control terminal b provides charging power for the charging mobile information collection terminal a for charging.

[0025] The charging mobile information collection terminal a is provided with an LCM display module 12 of unlimited type and mode, an input module 13 of unlimited type and number of buttons, a power control logic module 18, a charging chip 19, a load switch 20 and an LDO voltage stabilizing unit 21, wherein the LCM display module 12 and the input module 13 constitute a human-computer interaction unit 2, which is used to set a suitable temperature and humidity range, complete power on and off operations, etc., the wireless communication unit 1, the main control MCU unit 3 and the temperature and humidity sensor unit 5 constitute the basic functional circuit of the charging mobile information collection terminal a, and the electrical contact 17, the power control logic module 18, the charging chip 19, the load switch 20 and the LDO voltage stabilizing unit 21 constitute the power management unit 4 of the charging mobile information collection terminal a.

The power supply voltage required for the output of the switch quantity and voltage and current analog control signals in the drive control output unit 31 is usually higher than the working voltage of the main control MCU unit 28, the temperature and humidity sensor unit 2, the LCM display module 22, the input module 23 and related circuits. Therefore, the input power supply voltage takes the highest voltage requirement among the required voltages as the power input voltage, usually 12V or 24V, to meet the working power supply voltage of the switch quantity output part composed of relays, the working power supply voltage of the analog quantity output part of 0-10V, 4-20mA or other similar standards, and other parts that require lower voltage to work are provided by the power supply output by the BUCK step-down unit 27 and the LDO voltage regulator unit 230.

[0029] The output drive unit 11 includes a drive control output unit 31, an IOT unit 32 and an infrared transmitting unit 33, which are provided with unlimited number and type, wherein the drive control output unit 31 outputs the required control signal, and the output control signal includes but is not limited to a switch signal, a voltage analog signal, a current analog signal and a PWM signal to adapt to the control input signal requirements of different temperature and humidity adjustment devices; the IOT unit 32 is used to connect the adjustment device, remote control device and control APP application connected by IOT, and the IOT unit 32 is electrically connected to the serial port of the main control MCU unit 2 8 through the serial port; the infrared transmitting unit 33 is used to send the coded signal output by the main control MCU unit 2 8, which can control the conventional air conditioner for adjusting the temperature, the switch signal is used to start and stop the power-on access and shutdown operations of the humidification, dehumidification equipment and heating equipment, and the analog signal and PWM signal are used to control the gear of the gear adjustment device or the gear of the linear stepless adjustment device.

[0031] The working process of the charging mobile information collection terminal a in this specific implementation mode is as follows:

[0032] When the rechargeable battery of the charging mobile information collection terminal a needs to be charged, the charging mobile information collection terminal a is connected to the fixed control terminal b so that the electrical contact 17 is electrically connected to the electrical contact 2 29. The fixed control terminal b serves as the charging power supply of the charging mobile information collection terminal a. The charging power supply is connected to the charging chip 19TP4054 through the electrical contact 17 to charge the rechargeable battery. At the same time, the LDO voltage regulator unit 1 21 is powered through the anti-backflow diode of model SS14F to meet the working power supply requirements of the charging mobile information collection terminal a.

[0033] The charging power supply in this specific implementation is used as a signal of the control logic of the power control logic module 18 to identify whether there is power input. When there is charging power input, the load switch 20 is used to turn off the power supply of the charging battery, and only the charging power supply is used to power the charging mobile information collection terminal a system. Conventional load switches 20, such as MT9700 type USB load switches, are usually highly effective controls, and the load switch can be turned off by converting the input voltage from high voltage to low voltage. In this logic state, the power control logic module 18 uses a non-gate composed of integrated or discrete components to achieve the required control logic. When the charging power disappears, the input voltage of the power control logic module 18 changes from high voltage to low voltage, and the non-gate outputs a high voltage to turn on the load switch 20, which is powered by the charging battery; the charging mobile information collection terminal a is composed of a temperature and humidity sensor unit 5, which detects the ambient temperature and humidity under the coordinated control of the main control MCU unit 3, and the detection data merges the operation instructions and parameters of the human-computer interaction unit 2 through the wireless communication unit 3 16 and the fixed control terminal b for data transmission to complete the required temperature and humidity detection and control requirements.
