[0002] The HVAC system refers to the heating, ventilation and air-conditioning system inside a building. In the commercial field, the application of the HVAC system is also particularly extensive. For example, commercial central air conditioning is an important component of it. It uses a centrally controlled equipment system to complete air treatment, air delivery and indoor conditioning. It is suitable for various commercial and public places such as shopping malls, office buildings, hotels, hospitals, etc. In general, the HVAC system plays a vital role in modern architecture and life, providing people with a comfortable and healthy indoor environment.

[0003] While HVAC systems have powerful functions and a wide range of applications, they also face the problem of difficulty in maintenance and testing because they contain a large number of electronic control components. There are two main traditional ways to test HVAC system electronic control components: one is manual testing, which covers limited test points and generally only tests the main functions of the electronic control, such as power-on, cooling, heating, and temperature acquisition functions; the other is to develop a specific test tool for a certain electronic control component, which is suitable for a single electronic control with high demand.

[0034] The acquisition module is used to collect the status information data of the electronic control components in the HVAC equipment to be tested, and establish a communication relationship between the tooling hardware and the HVAC electronic control components.

[0035] Through the above technical scheme, this embodiment provides the main content of an all-in-one HVAC electrical control component intelligent testing system, in which the host computer sends test instructions to the tooling hardware, and then the working hardware tests the status information data of each electrical control component obtained by the acquisition module. Among them, the safety tester can perform safety inspections on the electrical control components of the HVAC equipment, and then perform functional qualification tests on each electrical control component through the functional test module. Therefore, the technical scheme can quickly complete the construction of the test scheme through the host computer selection and configuration combination, and quickly put into production testing and generate benefits.

[0036] The human-computer interaction terminal is used to input basic information of the HVAC equipment to be tested and output test results;

[0037] The instruction production module is used to issue instructions to the tooling hardware according to preset test rules;

[0038] The storage center is used to receive and store information data fed back by tooling hardware.

[0039] Through the above technical scheme, this embodiment provides the specific composition and functions of the upper computer, and the basic information of the HVAC equipment to be tested can be input into the human-computer interaction terminal by manual input. At the same time, the human-computer interaction terminal can output the test results to the technicians in time through the display interface. After the basic information of the HVAC equipment to be tested is obtained at the human-computer interaction terminal, the instruction generation module combines the basic information of the HVAC equipment to be tested with the preset test rules to issue a test instruction to the tooling hardware.

[0040] The preset test rules include:

[0041] The basic information of the HVAC equipment to be tested is obtained through the human-computer interaction terminal, and the basic information includes the types and models of the heating system, ventilation system and air-conditioning system included in the HVAC equipment to be tested. The basic information of the HVAC equipment to be tested is input into the trained calculation selection model, and the test items, test logic and test standards are output. Through the above technical scheme, the present embodiment provides the specific content of the preset test rules, and the preset test rules can determine the specific content of the test according to the basic information of the HVAC equipment to be tested. Specifically, the basic information of the HVAC equipment to be tested is first obtained through the human-computer interaction terminal, and the basic information includes the types and models of the heating system, ventilation system and air-conditioning system included in the HVAC equipment to be tested. Then, the basic information of the HVAC equipment to be tested is input into the trained calculation selection model, and the test items, test logic and test standards are output. Therefore, this technical scheme can perform targeted tests on different HVAC equipment, and provide software support for effectively expanding the scope of application of the test system of the present invention.

[0042] The functional test module includes a simulation unit and a test unit;

[0043] The simulation unit is used to provide simulated loads for each electronic control component during the test, including equivalent inductance and equivalent resistance;

[0044] The test unit is used to provide functional test items, and the functional test items include: variable frequency output test, star-delta conversion circuit test, AI test and capacitance test.

[0045] Through the above technical scheme, this embodiment provides a component unit of the functional test module. Specifically, the functional test unit includes a simulation unit and a test unit, wherein the simulation unit can provide simulated loads for each electronic control component during the test process. Because in order to achieve universality, it is necessary to use an equivalent circuit to simulate the load, which greatly increases the system design load degree. For example, if each model uses an actual compressor as a load, a large space is required to assemble these loads. The scheme provided by this embodiment can simulate the compressor load through equivalent inductance and resistance. BLDC fans, electronic expansion valves, etc. can provide equivalent test loads, thereby simplifying this part of the circuit and ensuring the effect of the load test during the test process. The test unit provides specific functional test items, including variable frequency output test, star-delta conversion circuit test, AI test and capacitance test. Among them, AI test and capacitance test can be specifically tested through PCB. This technical scheme provides modular functional testing, which has the advantages of easy assembly and expansion while ensuring the improvement of test efficiency.

[0046] The acquisition module comprises:

[0047] The electrical quantity sensor unit is used to collect DI phase sequence of relays, compressors and star-delta conversion circuits in the HVAC equipment to be tested;

[0048] Encoder, used to collect the rotation angle, speed and position information data of the stepper motor;

[0049] Photoelectric sensor, used to collect fan speed information data.

[0050] Through the above technical scheme, this embodiment provides the specific content of the acquisition module, which includes an electrical quantity sensor unit, an encoder and a photoelectric sensor. Among them, the electrical quantity sensor unit can be specifically composed of a voltage sensor and a current sensor, which can perform DI phase sequence acquisition on the relays, compressors and star-delta conversion circuits in the HVAC equipment to be tested. The encoder acquires the rotation angle, speed and position information data of the stepper motor, and the photoelectric sensor is used to collect the speed information of the fan.

[0051] The system further includes an edge computing module electrically connected to the acquisition module, wherein the edge computing module includes a preprocessing unit and a communication unit;

[0052] The pre-processing unit is used to perform comprehensive processing on the status information data of the HVAC electric control component, and establish a detection strategy for the HVAC equipment corresponding to the HVAC electric control component according to the comprehensive processing result;

[0053] The communication unit is used to send the detection strategy to the host computer module.

[0054] Through the above technical scheme, in this embodiment, through the setting of the edge computing module, it is possible to screen out the HVAC equipment that needs to be tested before testing the electrical control components of the HVAC equipment. Specifically, the acquisition module first obtains the status information of the electrical control components in the HVAC equipment, and the preprocessing unit performs comprehensive processing on the status information data of the electrical control components. The processing results generate a detection strategy for the HVAC equipment, and finally the detection strategy is sent to the upper computer module through the communication unit.

[0055] The process of comprehensive processing of the status information data of HVAC electronic control components includes:

[0056] By formula Calculate and obtain the status evaluation parameter S of HVAC equipment t ;

[0057] Among them, t1 and t2 are the left and right endpoints of the preset research interval respectively; ω1 and ω2 are preset weight coefficients; n(t) is the change value of the fan speed over time; n0(t) is the standard change curve of the fan speed in the preset research interval; T(t) is the change value of the ambient temperature of the HVAC equipment application scenario over time; T0(t) is the standard change curve of the ambient temperature in the preset research interval; ε1 and ε2 are preset proportional reference values;

[0058] The state evaluation parameter S t With the preset upper limit S cap Compare the size: If the state parameter evaluation value S t Exceeds the preset upper limit S cap , the electronic control components of the HVAC equipment are tested, and the basic information of the corresponding HVAC equipment is sent to the host computer through the communication unit.

[0059] Through the above technical solution, this embodiment provides a specific process for comprehensively processing the status information data of the HVAC electric control components. Because the fan speed and ambient temperature can usually reflect the working status of the HVAC equipment most timely and intuitively, and indirectly reflect the operating status of the electric control components, the formula Calculate and obtain the status evaluation parameter S of HVAC equipment t , and then the state evaluation parameter S t With the preset upper limit S cap The comparison is carried out, and the electric control component test is carried out on the HVAC equipment whose status evaluation parameters exceed the preset upper limit value, and the basic information of the HVAC equipment to be tested is sent to the host computer, so the test plan can be automatically generated without manual intervention. It should also be noted that n0(t), T0(t), weight coefficient and proportion reference value are all preset values, which can be obtained by fitting based on the system experimental data or the historical data of the standard test, and will not be described in detail here.

[0060] The process of establishing the detection strategy includes: screening out the HVAC equipment to be tested whose status evaluation parameters exceed the preset upper limit value; t -S cap Calculate and obtain the priority parameter p of the HVAC equipment to be tested; test the electric control components of each HVAC equipment to be tested in descending order of the priority parameter p. Through the above technical solution, this embodiment provides a process for establishing a detection strategy, firstly screening out the HVAC equipment to be tested whose status evaluation parameters exceed the preset upper limit value; then, through the formula p=S t -S cap The priority parameter p of the HVAC equipment to be tested is calculated. It can be seen from the formula that the larger the priority parameter, the greater the risk of abnormal electronic control components of the corresponding HVAC equipment. Therefore, the electronic control components of each HVAC equipment to be tested are tested in order from large to small priority parameters p.

[0061] Working principle of the present invention: The all-in-one HVAC electric control component intelligent testing system provided by the present invention is responsible for setting test items, test logic, test standards, test data storage, sharing, human-computer interaction, and interface display by the host computer. The tooling hardware platform can be centered on PLC and safety tester, responsible for executing the instructions issued by the host computer, and feeding back the results to the host computer. The safety test automatically completes the test by directly controlling the all-in-one functional safety tester and returns the test results. The functional tests of different electric controls are quite different. The functional interfaces of the HVAC electric control system are as follows: digital input port, digital output port, analog input port, analog output port, electronic expansion valve, compressor output port, star-delta conversion circuit, starting capacitor, fan, and variable frequency drive output. This system has made software and hardware testing plans for these functional module tests. Through the host computer selection and configuration combination, the test plan can be quickly built, and it can be quickly put into production testing and generate benefits.
