Embodiment 1

[0027] Such as figure 1 As shown, the present invention provides an indoor environment controller, including a liquid crystal screen 1, and a plurality of control buttons 2 are arranged below the liquid crystal screen, and are located in the indoor environment controller, the main control board is provided with a processor module; the main processor module is connected with the LCD screen and the control buttons.

[0028] figure 1 Among them, the main control board is located at the rear side of the upper cover 3 of the control panel and is blocked.

[0029] Further, the main processor module is also connected to the power supply box 5 through the control interface on the main control board, and the power supply box 5 is provided with a fan speed control port and a water valve control port for the ground rapid cooling and heating radiation module; and is also provided with Power inlet; the specific fan speed control port, the water valve control port of the ground rapid cool...

Embodiment 2

[0041] On the basis of Embodiment 1, the present invention also provides a working method of the indoor environment controller.

[0042] Further, the main control board is provided with a temperature measurement unit connected to the main processor module; the working method of the temperature measurement unit includes the following steps: step S1, rough measurement, that is, the temperature sensor signal is firstly differentiated through the rough measurement signal The amplification circuit sends it to the slave processor module for rough measurement, and obtains a rough temperature value; Step S2, fine measurement, that is, the slave processor module provides a corresponding signal to the fine measurement signal differential amplifier circuit according to the rough measurement temperature value. Precisely measure the reference voltage so that the temperature sensor signal can be re-measured to obtain a precise temperature value.

[0043] Further, the reference voltages of t...

Embodiment 3

[0047] On the basis of Embodiment 1 and Embodiment 2, the present invention also provides an optional implementation manner of a coarse-measurement signal differential amplifier circuit and a fine-measurement signal differential amplifier circuit.

[0048] Such as Figure 4 and Figure 5 The circuit diagrams of the rough test signal differential amplifier circuit and the fine test signal differential amplifier circuit are respectively shown.

[0049] Such as Figure 4 , specifically, the rough measurement reference voltage circuit adopts a series voltage divider circuit, the resistor R11 and the resistor R22 form a rough measurement reference voltage circuit, and the rough measurement reference voltage circuit is connected with a differential comparator (composed of U1B), the port ADIN is connected to the output end of the first multi-channel analog switch, and the port AD_1 is connected to the first AD conversion module.

[0050] Such as Figure 5 , the fine measurement s...

The indoor environment controller includes a liquid crystal screen, a plurality of control keys are arranged under the liquid crystal screen, and a main control board is provided with a processor module; The processor module is connected with the LCD screen and the control buttons; the indoor environment controller of the present invention can conveniently obtain the reading of the indoor environment and perform corresponding control through the LCD screen and the buttons.

Description

technical field [0001] The invention relates to an indoor environment controller, in particular to an indoor environment controller for a central air conditioner and a working method thereof. Background technique [0002] For central air conditioners, in order to facilitate the control of the fans distributed indoors, control panels are placed indoors. However, the traditional control panel has a single function and cannot intuitively display indoor environmental parameters, so it is inconvenient to operate. Contents of the invention [0003] The object of the present invention is to provide an indoor environment controller and a working method, so that the indoor environment parameters can be displayed more intuitively and the controllability can be improved. [0004] In order to solve the above-mentioned technical problems, the present invention provides a kind of indoor environment controller, comprises liquid crystal screen, is provided with some control buttons below ...
