Description

Technical Field

[0001] This invention relates to the field of air conditioner after-sales service system technology, and in particular to an air conditioner after-sales service system based on a digital remote control. Background Technology

[0002] Currently, in the development, testing, and after-sales maintenance of air conditioning systems, after sending a command to the air conditioner to enter test mode using a code-generating device, different test codes are transmitted to the air conditioning system for reception. Based on the type of test code received, various real-time operating parameters of the current air conditioning system will be displayed on the digital tube display panel of the indoor unit, such as indoor temperature, indoor coil temperature, and operating current. This provides users and maintenance personnel with accurate identification and reference based on the system status.

[0003] Due to the large number of status parameters and test codes, the method of sending infrared codes using physical buttons is extremely complex and cumbersome, resulting in low efficiency in code sending and debugging, and potentially causing incorrect code types. Currently, air conditioner repair requires entering repair mode using a specific button combination on the remote control and then repeatedly triggering the physical buttons on the remote control to obtain certain parameter settings through infrared encoding. This is very inconvenient, resulting in extremely low repair efficiency and low operability.

[0004] Furthermore, due to the physical display limitations of the digital tube in the indoor unit's display module, some detection parameters are difficult to display on the interface for the inspectors to read in a timely manner, and it is even necessary to manually trigger the display of individual parameters, which is very inconvenient and extremely inefficient.

[0005] After 2000, some testing technologies emerged, and hardware devices were designed that use external air conditioning repair instruments or tools. After connecting to the indoor and outdoor units, these devices can be remotely controlled and have their parameters directly adjusted, solving some of the aforementioned technical problems. However, these air conditioning repair instruments or tools have hardware costs, requiring additional purchase and configuration, which increases the overall cost. Summary of the Invention

[0048] Figure 2 This is a schematic diagram of the test sending submodule of the present invention. Detailed Implementation

[0049] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] like Figures 1 to 2 As shown in the figure, an embodiment of the present invention proposes an air conditioner after-sales service system based on a digital remote control, comprising:

[0051] An air conditioning system, wherein the air conditioning system is equipped with a communication module, the communication module being used to collect the operating data of the air conditioning system and receive test commands;

[0052] The mobile control module is used to identify the air conditioning system under test, establish a Bluetooth wireless connection with the air conditioning system under test, perform normal command control on the air conditioning system under test based on the operating data, send test commands to the air conditioning system under test, and receive test data returned by the air conditioning system under test.

[0053] The server module is used to receive test data uploaded by the mobile control module and send after-sales maintenance data to the mobile control module.

[0054] The working principle of the above technical solution is as follows: In actual use, during any process such as R&D testing, commodity inspection, after-sales testing, and return for repair, the air conditioning system to be tested can be paired and verified with the mobile control module via Bluetooth, and repair work can be performed in any of the above processes. The mobile control module can be any smartphone, tablet, or smart hardware capable of deploying programs, which allows the code sending program to be directly changed from the traditional infrared method, tooling hardware, and DIP switch to a highly universal mobile phone software, and to use Bluetooth wireless connection.

[0055] The beneficial effects of the above technical solution are as follows: Through the design of the above solution, the coding program is changed from traditional tooling hardware to a universal mobile phone software using wireless communication coding method, which is convenient to use and saves hardware costs; at the same time, Bluetooth is used to connect with the air conditioning system, which solves the limitations of traditional infrared coding method such as the relative geographical location requirements of people and air conditioning system, space filling limitations, and angle position limitations. When used in the maintenance system, this allows maintenance personnel to control the coding of the indoor unit while observing the outdoor unit in single-person mode, which greatly improves the maintenance efficiency of a single person, and the coding is more accurate and faster.

[0056] In one embodiment, the motion control module includes:

[0057] The connection submodule is used to detect all air conditioning systems within a preset range, obtain air conditioning system distribution data, determine the air conditioning system to be tested based on the air conditioning system distribution data, and establish a Bluetooth wireless connection with the air conditioning system to be tested.

[0058] The test sending submodule is used to send code test commands to the air conditioning system under test;

[0059] The parameter display submodule is used to receive the test data returned by the air conditioning system under test after receiving the code test command, and to display it in real time on the interactive interface.

[0060] The working principle and beneficial effects of the above technical solution are as follows: In actual use, the connection submodule will detect all air conditioning systems within the preset range and obtain the distribution data of the air conditioning systems. The distribution data of the air conditioning systems will be displayed on the interactive interface, and the maintenance personnel will select and determine the air conditioning system to be tested. After the air conditioning system to be tested is determined, the connection submodule will connect with the communication module of the air conditioning system to be tested via Bluetooth, which can realize one-to-one and one-to-many control of the air conditioning system. After pairing, the user can send test commands to the air conditioning system to be tested through the test sending submodule according to the actual test requirements to complete the test requirements. It is suitable for testing multiple air conditioning systems to be tested together.

[0061] After receiving the test command, the air conditioning system under test will send back test data to the test data display module. The parameter display module will display the sent back test data in real time on the interactive interface, so that users can diagnose and repair the fault of the air conditioning system under test based on the specific situation of the feedback test data and their own experience. The repair data is uploaded to the server module for recording in real time.

[0062] Repair data sent through the server module allows repair personnel to bind relevant repair experience with machine models / faults based on their own repair experience. After uploading to the cloud, it can be easily viewed by others, improving overall repair efficiency. The system can automatically categorize repair experience, further enhancing repair expertise. Finally, a two-dimensional query based on fault type can further improve the accuracy of repair personnel's fault analysis, thereby improving repair efficiency once again.

[0063] In one embodiment, the motion control module further includes:

[0064] The basic control submodule is used to send ordinary commands to the air conditioning system under test based on the operating data, and to perform ordinary command control.

[0065] The working principle and beneficial effects of the above technical solution are as follows: The current operating status of the air conditioner can be obtained through operating data (such as air conditioning mode, temperature, etc.). Users can complete basic usage control of the air conditioning system under test through the basic control submodule, such as switching the working mode of the air conditioner from heating to cooling.

[0066] In one embodiment, the test sending submodule includes:

[0067] The function parameter unit is used to adaptively adjust the parameter range and type of the test command based on the function parameters input by the maintenance user.

[0068] A single instruction unit performs a first data interaction with the air conditioning system under test, and the single instruction unit performs the following operations:

[0069] This is used to edit single test instructions according to various test codes to obtain custom single test instructions. The custom single test instructions are sent to the air conditioning system under test through the single test instruction sending subunit. At the same time, the single test instruction sending subunit sends preset basic single test instructions and high-order single test instructions to the air conditioning system under test.

[0070] The frequency modulation unit performs a second data interaction with the air conditioning system under test, and is used to perform frequency modulation tests in different modes on all DC inverter drive devices in the air conditioning system under test. The frequency modulation unit performs the following operations:

[0071] In fixed-frequency mode, a fixed-frequency test command is sent to the air conditioning system under test according to the DC inverter drive device and frequency level selected by the user, so that the selected DC inverter drive device operates at the corresponding frequency parameters of the selected frequency level.

[0072] In frequency sweep mode, based on the DC inverter drive device, base frequency parameters, and step parameters selected by the user, a frequency sweep test command is sent to the air conditioning system under test, causing the selected DC inverter drive device to run at the corresponding frequency step with the selected base frequency parameters and step parameters.

[0073] The working principle of the above technical solution is as follows: In actual use, before sending test commands to the air conditioning system under test, the user first inputs functional parameters, including three types: model parameters, cooling and heating parameters, and light sensing parameters. The system will adaptively revise the parameter range and type of subsequent test commands based on the specific combination of the three functional parameters to avoid the debugging commands from failing due to incompatibility between the debugging commands and the current air conditioning system.

[0074] After completing the function parameter settings, the single-instruction module edits the single-test instructions according to various test codes to obtain custom single-test instructions. The custom single-test instructions are then sent to the air conditioning system under test through the single-test instruction sending subunit to complete the test. Alternatively, the single-test instruction sending subunit can send preset basic single-test instructions (e.g., trial operation, target frequency +, etc.) and advanced single-test instructions (e.g., blocking communication between indoor and outdoor units, blocking indoor fan failure, etc.) to the air conditioning system under test to complete the test. Usually, the advanced single-test instructions are hidden in the overall interactive interface, and only the basic single-test instructions are displayed to ensure the overall cleanliness of the interactive interface, avoid excessive clutter, and make it more convenient for users to debug and operate.

[0075] In addition to testing via a single instruction unit, frequency modulation units can be used to perform frequency modulation tests on all DC inverter drive devices within the air conditioning system under test in different modes. During fixed-frequency testing, a fixed-frequency test command is sent to the air conditioning system under test based on the user-selected DC inverter drive device and frequency level. This causes the selected DC inverter drive device to operate at the corresponding frequency parameters of the selected frequency level. For example, there are five frequency levels for compressors: rated cooling, intermediate cooling, minimum cooling, maximum cooling, and 1 / 4 cooling. By selecting one of these frequency levels for testing, and completing the test in fixed-frequency mode, the cooling / heating capacity of the air conditioning system under test can be detected in various ranges, meeting different testing needs and improving testing and maintenance efficiency. When using frequency sweep mode for testing, a frequency sweep test command is sent to the air conditioning system under test based on the user-selected DC inverter drive device, base frequency parameters, and step parameters. This causes the selected DC inverter drive device to operate at the corresponding frequency step parameters, such as motor-driven devices.

[0076] The beneficial effects of the above technical solution are as follows: Through the design of the above solution, a variety of rich test modes can be realized through the provided functional parameter unit, single instruction unit and frequency modulation unit, providing testers with a variety of rich test requirements, thereby improving test efficiency.

[0077] In one embodiment, the test sending submodule further includes:

[0078] A special process unit, which performs the following operations:

[0079] This is used to send special process test instructions to the air conditioning system under test. After receiving the special process test instructions, the air conditioning system under test automatically executes the preset optimal operating parameters and directly displays the correct operation of the user when the air conditioning system under test is running in the special process on the interactive interface. This allows the air conditioning system under test to run with the preset optimal operating parameters and outputs risk threshold parameters that match the current special process instruction flow.

[0080] The working principle and beneficial effects of the above technical solution are as follows: When a user needs to perform special process operations, such as refrigerant recovery operation mode and refrigerant charging operation mode, a special process test command is sent through the special process unit. The air conditioning system under test will automatically execute the preset optimal operating parameters, including: running time and compressor frequency, etc. The correct operation operation for the user to perform the special process test is directly displayed on the interactive interface through information prompts, thereby guiding the user to perform the correct operation. At the same time, when the special process test command is triggered, the system automatically allocates risk threshold parameters that match the current special process testing process. When the user performs a special process operation, if the operating parameters exceed the risk threshold parameters due to improper operation, the system can still provide stable protection for the equipment and the user.

[0081] In one embodiment, the single instruction unit further includes:

[0082] The time ratio coefficient setting subunit performs the following operations: based on the control ratio coefficient input by the maintenance user and after confirmation, it sends a time-reduction operation command to the air conditioning system under test, and proportionally shortens and lengthens the determination time of each operating mode of the air conditioning system under test.

[0083] The working principle and beneficial effects of the above technical solution are as follows: When there are too many test targets or the test phenomena are not easy to identify, if the parameter judgment time of each mode of equipment operation is not limited or expanded, the test and maintenance effect will be seriously affected. Therefore, when the time-shortening mode is triggered, the user can set the overall time ratio coefficient to meet different functional test needs and improve maintenance efficiency.

[0084] In one embodiment, the parameter display submodule includes:

[0090] The device status subunit is used to obtain the device status package based on the device status data returned by the air conditioning system under test, and display it on the display interface.

[0091] The working principle of the above technical solution is as follows: In actual use, through the basic information subunit, users can obtain data information such as the name, telephone number, and address of the user of the air conditioning system under test through the interactive interface; through the product information subunit, users can obtain data information such as the SN code, electronic control model, and software version of the air conditioning system under test through the interactive interface; through the fault information subunit, users can obtain data information such as the fault name, fault code (not shown), fault type (not shown), and fault details of the air conditioning system under test through the interactive interface; through the operating parameter subunit, users can obtain data information such as the test data and operating data returned by the air conditioning system under test through the interactive interface; and through the equipment status subunit, users can obtain information such as the outdoor operating current, refrigerant level, and compressor drive board temperature of the air conditioning system under test through the interactive interface.
