It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the implementation regulations.

[0050] See also Figure 1-2As shown, this embodiment provides an air-conditioning controller with high-reliability digital quantity and analog quantity IO, including: a self-test control module, the self-test control module is arranged inside the air-conditioning controller, the self-test control module is used to perform self-test on the output control circuit, the self-test control module includes: a digital self-test component and an analog self-test component, the digital self-test component is configured to judge whether the digital quantity self-test is qualified according to the digital quantity input result and the digital quantity output result of the output control circuit, and establish a digital quantity feedback report according to the detection result, the analog self-test component is configured to detect the analog quantity input result and the analog quantity output result of the output control circuit, judge whether the analog quantity self-test is qualified, and establish an analog quantity feedback report according to the detection result, and the self-test control module judges whether the output control circuit is qualified according to the digital quantity feedback report and the analog quantity feedback report.

[0051] Specifically, the function of the self-test control module is to automatically perform self-test operations on the output control circuit to ensure the stability and reliability of the air-conditioning controller. The self-test control module consists of two parts: a digital self-test component and an analog self-test component, which are responsible for the self-test of digital I / O and analog I / O respectively. The digital self-test component makes judgments based on the digital input and output results of the output control circuit, and evaluates the working status of the digital I / O by comparing the expected output and the actual feedback results. If the digital self-test is found to be unqualified during the self-test process, the digital self-test component will generate a detailed digital feedback report. The feedback report includes the error type and the time of occurrence information for subsequent maintenance and repair, which effectively eliminates control errors caused by hardware failures or abnormal signal transmission and ensures the operation of the air-conditioning controller. The analog self-test component is responsible for judging the analog input and output results of the output control circuit and determining whether the analog I / O is qualified. The analog I / O is used to control the fine parameters of temperature and humidity in the air conditioner, and its accuracy is directly related to the performance of the air conditioner controller. During the self-test process, the analog self-test component will detect the match between the analog input signal and the output signal of the output control circuit. If there is an unexpected situation, the analog self-test component will judge the analog self-test as unqualified and generate a corresponding analog feedback report, which records the analog I / O self-test situation in detail.

[0052] It is understandable that the self-test control module will comprehensively analyze the feedback reports of digital and analog quantities, and judge whether the output control circuit is qualified according to the self-test results. If the output control circuit passes the self-test, it means that the output control circuit components of the air conditioner controller are normal and can stably and reliably output digital and analog quantities, thus ensuring the stability and reliability of the air conditioner controller.

[0053] See also Figure 3As shown, in some embodiments of the present application, the digital self-test component is configured to determine whether the digital quantity self-test is qualified based on the digital quantity input result and the digital quantity output result of the output control circuit, and establish a digital quantity feedback report based on the detection result, including: the digital self-test component includes a digital input self-test unit, the digital input self-test unit is configured to determine the target waveform based on the digital quantity input, substitute the digital quantity input into the output control circuit, obtain the digital waveform of the signal input end, and determine whether the digital quantity input self-test is qualified based on the comparison result of the digital waveform and the target waveform.

[0054] In some embodiments of the present application, when determining whether the digital input self-test is qualified based on the comparison results of the digital waveform and the target waveform, it includes: when the digital waveform and the target waveform are consistent, it is judged that the digital input self-test is qualified; when the digital waveform and the target waveform are inconsistent, it is judged that the digital input self-test is unqualified. The digital input self-test unit establishes a digital input feedback report based on the result of the unqualified digital input self-test, and records the abnormal data of the digital input.

[0055] Specifically, the digital input self-test unit determines a target waveform according to the characteristics of the digital quantity input. The target waveform provides a benchmark for subsequent comparisons, reflecting the waveform that should be present when the digital quantity is input normally. The digital input self-test unit substitutes the digital quantity input into the output control circuit, and the output control circuit generates a corresponding digital waveform according to the digital quantity input signal. The digital input self-test unit collects the digital waveform at the signal input end of the output control circuit, and then the digital input self-test unit compares the obtained digital waveform with the target waveform. The comparison process mainly determines whether it meets expectations through the parameters of the period and amplitude. By comparing the digital waveform with the target waveform, the digital input self-test unit ensures the working state of the air-conditioning controller during operation and improves the stability of the air-conditioning controller. When the digital waveform is consistent with the target waveform, the digital input self-test unit determines that the digital quantity input self-test is qualified, and the air-conditioning controller can obtain accurate and reliable digital quantity input. When the digital waveform is inconsistent with the target waveform, the digital input self-test unit determines that the digital quantity input self-test is unqualified, which means that there is an abnormality in the output control circuit, thereby affecting the normal operation of the air-conditioning controller. When the digital input self-test fails, the digital input self-test unit will generate a digital input feedback report. The feedback report includes the error type and time information of the digital input, so that subsequent repairs can quickly locate the problem and take corresponding repair measures.

[0056] It can be understood that by comparing the digital waveform with the target waveform, the digital input self-test unit can accurately determine whether the digital input has passed the self-test, and potential problems can be detected in the early stage of a fault, thereby improving the reliability of the digital input in the output control circuit and thus enhancing the stability of the air-conditioning controller.

[0057] In some embodiments of the present application, the digital self-test component also includes a digital output self-test unit, which is configured to determine a target digital quantity output based on a digital quantity input, substitute the digital quantity input into an output control circuit, obtain an actual digital quantity output outputted from a signal output terminal, and determine whether the digital quantity output self-test is qualified based on a comparison result between the actual digital quantity output and the target digital quantity output.

[0058] In some embodiments of the present application, when determining whether the digital output self-test is qualified based on the comparison result of the actual digital output and the target digital output, it includes: when the actual digital output and the target digital output are equal, it is judged that the digital output self-test is qualified; when the actual digital output and the target digital output are not equal, it is judged that the digital output self-test is unqualified. The digital output self-test unit establishes a digital output feedback report based on the result of the digital output self-test failure, and records the data of the digital output abnormality.

[0059] Specifically, the digital self-test component also includes a digital output self-test unit, and the function of the digital output self-test unit is to detect whether the digital output in the output control circuit meets expectations. The target digital output is determined according to the digital input. The target digital output is obtained according to the control logic and actual needs. The target digital output is the result of the digital output expected to be obtained by the air-conditioning controller under normal operation. The digital output self-test unit substitutes the digital input into the output control circuit, and the output control circuit generates an actual digital output according to the digital input. The actual digital output is generated from the signal output end of the output control circuit. By comparing the difference between the actual digital output and the target digital output, the digital output self-test unit can determine whether the digital output self-test is qualified. If the actual digital output is consistent with the target digital output, the digital output self-test is deemed to be qualified. If there is a difference between the two, the digital output self-test is deemed to be unqualified, indicating that there is an abnormality in the output control circuit. The digital output self-test unit will generate a detailed digital output feedback report, so that subsequent repairs can quickly locate the problem and take corresponding repair measures.

[0060] It is understandable that the digital output self-test unit can timely detect the abnormality of the digital output in the output control circuit by comparing the actual digital output with the target digital output, and simplify the troubleshooting process based on the generated digital output feedback report. It ensures that the digital output of the air conditioner controller always meets the standard during operation, so that the air conditioner controller has reliable digital output.

[0061] See also Figure 4As shown, in some embodiments of the present application, the analog self-test component is configured to detect the analog input result and the analog output result of the output control circuit, determine whether the analog self-test is qualified, and establish an analog feedback report based on the detection result, including: the analog self-test component includes an analog input self-test unit, the analog input self-test unit is configured to set a time interval, collect target on-off data of the first solid-state relay and the second solid-state relay in the output control circuit according to the time interval, control the on-off state of the first solid-state relay and the second solid-state relay at the same time interval to obtain actual on-off data, and determine whether the analog input self-test is qualified based on the actual on-off data and the target on-off data.

[0062] In some embodiments of the present application, when judging whether the analog input self-test is qualified based on the actual on-off data and the target on-off data, it includes: when the actual on-off data and the target on-off data are consistent, it is judged that the analog input self-test is qualified; when the actual on-off data and the target on-off data are inconsistent, it is judged that the analog input self-test is unqualified; the analog input self-test unit establishes an analog input feedback report based on the result of the analog input self-test failure, and records the abnormal data of the analog input.

[0063] Specifically, the analog self-test component is a component used to self-test the accuracy of the analog input in the output control circuit. The set time interval is preferably 60S, which can be adjusted according to actual needs. The analog input self-test unit collects the target on-off data according to the set time interval. The target on-off data is the ideal on-off state of the first solid-state relay and the second solid-state relay under normal operation of the air-conditioning controller. The analog input self-test unit controls the on-off state of the first solid-state relay and the second solid-state relay according to the same time interval to obtain the actual on-off data. The analog input self-test unit compares the actual on-off data with the target on-off data. If the data of the two are consistent, it means that the analog input is working normally and the self-test is qualified. If the data of the two are inconsistent, it means that there is a problem with the analog input in the output control circuit and the self-test is unqualified. When it is judged to be unqualified, the analog input self-test unit will automatically generate an analog input feedback report, record the difference between the actual on-off data and the target on-off data, and provide the time and information of the abnormality, thereby improving the reliability of the analog input in the output control circuit, thereby improving the stability of the air-conditioning controller.

[0064] It can be understood that by self-checking the analog input, potential problems can be detected at the early stage of the failure, so that the air conditioning controller has good reliability.

[0065] In some embodiments of the present application, the analog self-test component also includes an analog output self-test unit, which is configured to determine a target analog output based on an analog input, substitute the analog input into an output control circuit, obtain an actual analog output outputted from a signal output terminal, and determine whether the analog output self-test is qualified based on a comparison result between the actual analog output and the target analog output.

[0066] In some embodiments of the present application, when determining whether the analog output self-test is qualified based on the comparison result of the actual analog output and the target analog output, it includes: setting an analog threshold, recording the ratio of the actual analog output to the target analog output as Q, when Q is equal to the analog threshold, then the analog output self-test is judged to be qualified, when Q is not equal to the analog threshold, then the analog output self-test is judged to be unqualified, the analog output self-test unit establishes an analog output feedback report based on the result of the unqualified analog output self-test, and records the abnormal analog output data.

[0067] Specifically, the analog output self-test unit determines the corresponding target analog output according to the analog input, and the target analog output is the ideal output value set according to the analog input and the control logic. The analog output self-test unit substitutes the analog input into the output control circuit, and generates the actual analog output at the signal output end through the output control circuit. The analog output self-test unit compares the actual analog output with the target analog output. An analog threshold is set, and the analog threshold is preferably 1. It can also be adjusted according to actual needs. The ratio of the actual analog output to the target analog output is recorded as Q. When Q is equal to the set analog threshold, it means that the actual analog output is consistent with the target analog output, and the analog output self-test is judged to be qualified. If Q is not equal to the analog threshold, it means that there is a deviation or error in the analog output in the output control circuit, and the analog output self-test is judged to be unqualified. If the analog output self-test fails, the analog output self-test unit will generate an analog output feedback report to record the difference between the actual analog output and the target analog output, and indicate the situation where the Q value does not reach the set threshold. The analog output feedback report helps to quickly identify and locate the problem.

[0068] It can be understood that the analog output self-test unit can promptly detect the deviation of the analog output by detecting the difference between the actual analog output and the target analog output, thereby avoiding the initial abnormality of the output control circuit that may cause the air-conditioning controller to malfunction or become instability, allowing the air-conditioning controller to obtain accurate analog output, thereby ensuring the stability and reliability of the air-conditioning controller.

[0069] In some embodiments of the present application, the self-test control module determines whether the output control circuit is qualified based on the digital quantity feedback report and the analog quantity feedback report, including: when any one of the digital quantity input feedback report, the digital quantity output feedback report, the analog quantity input feedback report and the analog quantity output feedback report exists, the self-test control module determines that the output control circuit is unqualified; when the digital quantity input feedback report, the digital quantity output feedback report, the analog quantity input feedback report and the analog quantity output feedback report do not exist, the self-test control module determines that the output control circuit is qualified.

[0070] The self-check control module determines whether the output control circuit is qualified by checking the digital input feedback report, digital output feedback report, analog input feedback report and analog output feedback report. When any one of the feedback reports exists, it means that there are abnormalities or deviations in the digital input, digital output, analog input and analog output during the self-check process. If there is a situation that does not meet the standards, fault analysis and repair must be performed, and the self-check control module will determine that the output control circuit is unqualified. On the contrary, when all four feedback reports do not exist, it means that the digital input, digital output, analog input and analog output are all as expected during the self-check process, and no abnormalities or deviations are found. The self-check control module determines that the output control circuit is qualified, so that it provides reliable digital input, digital output, analog input and analog output, ensuring the stability of the output control circuit, thereby improving the reliability of the air-conditioning controller.

[0071] In summary, the beneficial effects of the present invention are: the air-conditioning controller ensures the stability and reliability of the output control circuit through the self-checking control module. The self-checking control module is responsible for detecting and verifying the digital quantity and the analog quantity respectively, so that the air-conditioning controller has reliable digital quantity and analog quantity signals. Through the comprehensive self-checking of the output control circuit, the air-conditioning controller can timely identify potential abnormal conditions before the problem occurs, thereby reducing the risk of failure of the air-conditioning controller due to undetected faults, and avoiding failure or misoperation of the air-conditioning controller due to abnormal output control circuits. Once an abnormality occurs, the digital quantity feedback report and the analog quantity feedback report record the abnormal situation in detail to help users quickly locate the problem. Targeted measures are taken based on the digital quantity feedback report and the analog quantity feedback report, which reduces the time for troubleshooting the output control circuit fault and ensures the stability of the air-conditioning controller.
