Embodiment Construction

[0058] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] Formaldehyde sensor module of the present invention, as figure 1 As shown, the formaldehyde sensor module includes: a processor 1001 , such as a CPU, a user interface 1002 , a memory 1003 , and a communication bus 1004 . Wherein, the communication bus 1004 is used to realize connection and communication between these components. The user interface 1002 may include a display screen (Display), an input unit such as a remote controller. The memory 1003 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1003 may also be a storage device independent of the foregoing processor 1001 .

[0060] Those skilled in the art can understand that, figure 1 The structure of the formaldehyde sensor module shown in the formaldehyde sensor module does not con...

Abstract

The invention discloses a self-diagnosis method of a formaldehyde sensor module. The formaldehyde sensor module comprises a formaldehyde sensor and an MCU (Microprogrammed Control Unit). The self-diagnosis method of the formaldehyde sensor module comprises the following steps: when the MCU is electrified on the formaldehyde sensor module or receives a self-inspection instruction, executing a self-diagnosis program of the formaldehyde sensor module; and according to self-diagnosis results, controlling the formaldehyde sensor to enter a standby state or a locked state correspondingly. The invention further discloses the formaldehyde sensor module and a computer readable storage medium. By adopting the self-diagnosis method, situations can be fed back in time before detection accuracy degradation or complete failure of the formaldehyde sensor, and thus the accuracy of formaldehyde sensor detection results can be ensured.

Description

technical field [0001] The invention relates to the technical field of formaldehyde detection, in particular to a formaldehyde sensor module, a self-diagnosis method of the formaldehyde sensor module and a computer-readable storage medium. Background technique [0002] Formaldehyde sensor modules currently on the market mainly use the electrochemical sensor method, using formaldehyde gas molecules to electrochemically react at the sensitive electrode materials of the formaldehyde sensor module. Signals are also different. By measuring the change of this electrical signal, and through a series of processing, it can be converted into the corresponding concentration of formaldehyde gas. During the use of the formaldehyde sensor module, when the formaldehyde gas reacts with the electrode material, the electrodes and other materials will be continuously consumed, and after a certain period of use, the accuracy of the output signal of the formaldehyde sensor module will drop or e...
