Aiming at the problem that the air conditioning effect is poor due to drift in the aging of the existing carbon dioxide sensor, the embodiment of the invention provides a calibration method and a calibration device for the carbon dioxide sensor and an air conditioner.
To facilitate understanding of the present embodiment, a detailed description will be given below of a calibration method for a carbon dioxide sensor according to an embodiment of the present invention. The air conditioner comprises an indoor unit 1 and an outdoor unit 2 which are connected, wherein the indoor unit 1 comprises a controller 10, and a carbon dioxide sensor 20, a fresh air module 30, a display module 40 and a communication module 50 which are in communication connection with the controller 10, and the specific installation modes of the controller 10, the carbon dioxide sensor 20, the fresh air module 30, the display module 40 and the communication module 50 can be set according to actual conditions, which is not limited in the embodiment of the invention.
In practical applications, the controller 10 can not only control the operating status of the carbon dioxide sensor 20 by communication, such as whether to detect or perform calibration; the working state of the fresh air module 30 can be controlled, wherein the fresh air module 30 comprises a valve and a fan, and the controller 10 can control the valve to be opened or closed so as to control whether fresh air flows into the air conditioner or not, thereby regulating the indoor air.
In addition, the control module can also display the working state of the air conditioner through the display module 40, for example, when the air conditioner works, the display module 40 represents the working state through an indicator light (such as a green light), displays the temperature information set by the user through the air conditioner remote controller, and the like, and can be specifically set according to the actual situation. And, the controller 10 can also communicate with an external device through the communication module 50, where the communication module 50 includes but is not limited to wireless communication technology WIFI communication, and the external device includes but is not limited to a mobile device, such as a mobile phone, a palm computer, etc., so that a user can control the operation of the air conditioner through a mobile phone APP (Application, mobile phone software), such as controlling the state of the air conditioner, setting the temperature, etc., thereby satisfying the user's various control mode requirements and improving the user experience.
Based on the air conditioner, an embodiment of the present invention provides a calibration method for a carbon dioxide sensor, where an execution main body is a controller, and as shown in fig. 2, the method includes the following steps:
step S202, judging whether a fresh air module is started or not;
specifically, the back is gone up to the controller of indoor set, judges whether work is opened to the new trend module in real time, and wherein, the new trend module includes valve and fan, and the controller can judge whether the new trend module is opened through the valve state, also can judge whether the new trend module begins through the rotational speed of fan etc. specifically can set up according to actual conditions.
Step S204, if yes, after the fresh air module operates for a first time interval, acquiring a first carbon dioxide standard value and a first carbon dioxide concentration value sent by a carbon dioxide sensor at the current moment; the first carbon dioxide reference value is a carbon dioxide reference concentration value issued by a meteorological department at the current moment of the position of the air conditioner;
when the controller judges the new trend module when beginning, all open like valve and fan, make statistics of the running duration of new trend module, when the running duration is first time interval, first time interval satisfies here: 20 min-60 min, which can be set according to the actual situation; the controller obtains a first carbon dioxide concentration value sent by the carbon dioxide sensor at the current moment, and obtains a first carbon dioxide reference value, wherein the first carbon dioxide reference value is a carbon dioxide reference concentration value issued by a meteorological department at the current moment, and the carbon dioxide reference concentration values issued by the meteorological department may be the same or different with the different moments.
It should be noted that, the controller may also determine the location of the air conditioner through the communication module, for example, perform positioning through wifi and a network server, and obtain the location of the air conditioner, and further obtain the carbon dioxide reference concentration value issued by the meteorological department where the air conditioner is located, so as to calibrate the carbon dioxide sensor according to the carbon dioxide reference concentration value issued by the meteorological department where each air conditioner is located, and further ensure the accuracy of calibration of the carbon dioxide sensor of each air conditioner.

One possible way of checking is as follows: calculating an error value of the first carbon dioxide reference value and the first carbon dioxide concentration value; and calibrating the reference value based on the error value to obtain the calibrated carbon dioxide sensor. For convenience of understanding, it is illustrated here that if the first carbon dioxide reference value is greater than the first carbon dioxide concentration value, the error value is positive, which indicates that the carbon dioxide concentration collected by the carbon dioxide sensor is lower than the actual value, and the error value is added on the basis of the reference value to obtain a calibrated reference value; and if the first carbon dioxide reference value is smaller than the first carbon dioxide concentration value, the error value is negative, and the carbon dioxide concentration acquired by the carbon dioxide sensor is higher than the actual value, so that the error value is added on the basis of the reference value (at the moment, the error value is negative) to obtain a calibrated reference value, and the calibrated reference value is used as the reference value of the calibrated carbon dioxide sensor.
It should be noted that, in a part of the scenarios, the offset value may also be calibrated, for example, the offset value is calibrated through an error value, and the like, and the setting may be specifically performed according to an actual situation, and details are not described here in the embodiment of the present invention.

Specifically, the controller may obtain a third carbon dioxide concentration value sent by the carbon dioxide sensor at a preset third time interval; here, the third time interval satisfies: 1 s-60 s, and when receiving a third carbon dioxide reference value set by a user, calibrating the carbon dioxide sensor according to the third carbon dioxide concentration value received at the moment. It should be noted that, for the manual calibration mode that the user sets the third carbon dioxide reference value, after the controller receives the third carbon dioxide reference value, the controller forcibly controls to calibrate the carbon dioxide sensor without judging the state of the fresh air module, so that various calibration control modes are satisfied, and the user experience is improved.
