Description

Technical Field

[0001] This invention relates to the field of industrial equipment fault diagnosis technology, and in particular to a multifunctional air compressor fault diagnosis device. Background Technology

[0002] Air compressors are commonly used power equipment in industrial production sites, and their operating status directly affects the stability of the air supply to the production system. Air compressor faults typically involve multiple parts, including the control circuit, drive load, pressure sensor, temperature sensor, and controller communication link. Currently, troubleshooting usually requires maintenance personnel to carry multimeters, clamp meters, pressure sensor calibrators, temperature sensor calibrators, and communication testing equipment to perform separate tests on each component.

[0003] The above-mentioned testing methods have at least the following shortcomings: First, the various testing instruments are independent of each other, requiring maintenance personnel to frequently switch instruments and testing lines, making the on-site wiring process complex; Second, the test data usually relies on the experience of maintenance personnel for manual judgment, making it difficult to quickly generate maintenance prompts corresponding to air compressor faults; Third, the air compressor room has dense piping and limited operating space, making the testing equipment unstable, requiring maintenance personnel to support the equipment while connecting the wires, affecting testing efficiency; Fourth, the testing cables are prone to tangling, dragging, or falling off on-site, affecting the reliability of continuous testing.

[0004] Therefore, it is necessary to provide a dedicated fault diagnosis device that can simultaneously perform electrical parameter detection, pressure / temperature sensor signal simulation and detection, fault information matching and display, and equipment fixing support at the air compressor site. Summary of the Invention

[0005] The purpose of this invention is to provide an air compressor fault diagnosis device to solve the problems of scattered detection instruments, inconvenient storage of detection lines, difficulty in placing on-site equipment, and reliance on manual experience in the existing air compressor fault diagnosis process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An air compressor fault diagnosis device includes a diagnostic device body, which contains a processor, a data storage unit, a power supply, and a multi-channel detection and simulation module electrically connected to the processor.

[0008] The data storage unit stores a mapping table between detection items, normal threshold ranges, abnormality types, fault codes, and maintenance prompts. The processor matches the detection values ​​output by the multi-channel detection and simulation modules with the mapping table and controls the display to show the corresponding fault codes and maintenance prompts.

[0009] The rear end of the main body of the diagnostic device is provided with a detection line storage cavity. A winding wheel is rotatably installed inside the detection line storage cavity. The detection line electrically connected to the multi-channel detection and simulation module is wound on the winding wheel. A cover is provided at the detection line storage cavity to cover the detection line storage cavity.

[0010] The rear side of the main body of the diagnostic device is provided with an adaptive fixing component. The adaptive fixing component includes a metal bracket fixed to the rear side of the main body of the diagnostic device, a clamp rotatably connected to the metal bracket, an annular airbag fixed to the inner circumference of the clamp, and an air pump connected to the annular airbag. The air pump is used to inflate the annular airbag so that the clamp is clamped to air compressor pipelines of different diameters.

[0011] Furthermore, the clamp includes a first clamp body and a second clamp body that are hinged to each other, and the ends of the first clamp body and the second clamp body away from the hinge end are connected by a locking bolt.

[0012] Furthermore, the locking end of the clamp is provided with multiple adjustment holes arranged at intervals along the circumference of the clamp, and the locking bolt passes through different adjustment holes to adjust the diameter of the clamp.

[0013] Furthermore, the metal bracket and the clamp are connected by a damping shaft, which is used to adjust the display angle of the main body of the diagnostic equipment relative to the air compressor pipeline.

[0014] Furthermore, the inner circumferential side of the annular airbag is provided with an elastic anti-slip layer.

[0015] Furthermore, an air pipe is provided between the air pump and the annular airbag, and a deflation valve is provided on the air pipe.

[0019] Furthermore, the processor controls the multi-channel detection and simulation module to perform at least one of the following operations based on the detection instructions received by the wireless communication module: detection channel selection, detection start, analog signal output, detection data reading, and historical record upload.

[0020] The beneficial effects of this invention are as follows: 1. This invention integrates the detection of voltage, current, and resistance in the air compressor control circuit, as well as the simulation and detection of pressure and temperature sensing signals, into the same diagnostic device body, reducing the need for on-site maintenance personnel to carry and switch multiple independent testing instruments.

[0021] 2. The data storage unit of the present invention stores a mapping table between detection items, normal threshold ranges, abnormality types, fault codes and maintenance prompts.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] It should also be noted that all standard parts used in this invention can be purchased commercially, and can be customized according to the description and drawings. Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances, and unless explicitly limited, the machinery, parts, and equipment can all adopt conventional models in the prior art.

[0032] In this document, the term "comprising" is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] Example: Reference Figures 1 to 6 As shown, this embodiment of the invention provides an air compressor fault diagnosis device, including a diagnostic device body 100. The diagnostic device body 100 can be a portable test box structure, and its shell can be made of engineering plastics, aluminum alloys, or other materials with certain mechanical strength, so that maintenance personnel can carry it to the air compressor site for testing.

[0034] The main body 100 of the diagnostic device includes a processor 110, a data storage unit 111, a wireless communication module 112, a power supply 113, and a multi-channel detection and simulation module 120. The processor 110 serves as the control core of the main body 100 and is electrically connected to the data storage unit 111, the wireless communication module 112, the power supply 113, the multi-channel detection and simulation module 120, the display 150, and the printer 160. The power supply 113 provides power to the processor 110, the multi-channel detection and simulation module 120, the display 150, the wireless communication module 112, and the printer 160.

[0035] The multi-channel detection and simulation module 120 includes a voltage detection module 121, a current detection module 122, a resistance detection module 123, a pressure signal simulation and detection module 124, a temperature signal simulation and detection module 125, and a communication bus diagnostic module 126.

[0036] The voltage detection module 121 is used to detect the voltage value of the air compressor control circuit, power supply circuit, or sensor power supply terminal. In one embodiment, the voltage detection module 121 may include a voltage divider sampling circuit and an analog-to-digital converter circuit to convert the acquired voltage signal into a digital signal that the processor 110 can recognize.

[0037] The current detection module 122 is used to detect the operating current of loads such as air compressor motors, solenoid valves, and relay coils. As one implementation, the current detection module 122 can employ a sampling resistor, a Hall current sensor, or a clamp-on current acquisition structure to detect different load current states.

[0038] The resistance detection module 123 is used to detect the continuity of air compressor circuits, contactor contact resistance, motor winding resistance, or sensor circuit resistance. In one implementation, the resistance detection module 123 can output a detection current through a constant current source and calculate the resistance value of the object under test based on the acquired voltage.

[0039] The pressure signal simulation and detection module 124 is used to output and acquire pressure sensing signals. In one implementation, the pressure signal simulation and detection module 124 can output or acquire a 4-20mA, 0-5V or 0-10V pressure sensing signal to determine whether the pressure input terminal of the pressure sensor, pressure transmitter or air compressor controller is abnormal.

[0040] The temperature signal simulation and detection module 125 is used to output and acquire temperature sensing signals. In one implementation, the temperature signal simulation and detection module 125 can be used to simulate or acquire PT100, NTC thermistor, or thermocouple signals to determine whether the temperature input terminal of the air compressor temperature sensor or controller is abnormal.

[0041] The communication bus diagnostic module 126 is used to detect the communication status of the air compressor controller. In one implementation, the communication bus diagnostic module 126 can be used to detect CAN bus, RS485 bus, or Modbus communication signals, including communication connection status, communication rate, data frame reception status, or communication anomaly status.

[0042] The data storage unit 111 stores a fault diagnosis mapping table, see Figure 7 The fault diagnosis mapping table includes detection items, normal threshold ranges, abnormality types, fault codes, fault causes, and maintenance prompts. The processor 110 receives the detection values ​​output by the multi-channel detection and simulation module 120 and compares them with the normal threshold ranges in the fault diagnosis mapping table. When a detection value exceeds the normal threshold range for the corresponding detection item, or when an abnormality such as open circuit, short circuit, overcurrent, overvoltage, or no response occurs in the detection signal, the processor 110 generates the corresponding fault code and retrieves the appropriate fault cause and maintenance prompts.

[0043] For example, when the pressure signal simulation and detection module 124 detects that the pressure sensor output current is below 4mA, the processor 110 can determine that the pressure sensor is disconnected, has an abnormal power supply, or has poor signal line contact, and display the corresponding fault code and maintenance prompt on the display 150. When the temperature signal simulation and detection module 125 detects that the resistance value corresponding to the PT100 signal is open, the processor 110 can determine that the temperature sensor is open or the terminal is loose, and output the corresponding prompt. Thus, maintenance personnel can quickly troubleshoot based on the fault codes and maintenance prompts on the display 150.

[0044] The front of the diagnostic equipment body 100 is equipped with multiple control switches 141 and corresponding status indicator lights 142. The control switches 141 are used to select test items, start tests, or switch analog output modes. The status indicator lights 142 indicate the abnormal detection status of the corresponding test module. When a test module detects an abnormality, the processor 110 controls the corresponding status indicator light 142 to illuminate, allowing maintenance personnel to quickly identify the type of abnormality.

[0045] A display 150 is also provided on the front side of the main body 100 of the diagnostic equipment. The display 150 is used to display test items, test values, fault codes, fault causes, and maintenance prompts. As one implementation, the display 150 can be a touch display to receive commands for test mode selection, historical record query, or report output.

[0046] The rear end of the diagnostic equipment body 100 is provided with a test cable storage cavity 130. The test cable storage cavity 130 is an outwardly opening concave structure, and a winding wheel 131 is rotatably mounted inside. The test cable 132 is wound onto the winding wheel 131, and one end of the test cable 132 is electrically connected to the multi-channel detection and simulation module 120, while the other end is used to connect to the test terminal of the air compressor or the sensor interface. A cover 133 is provided at the test cable storage cavity 130, and one end of the cover 133 is hinged to the diagnostic equipment body 100. The cover 133 is used to cover the test cable storage cavity 130 when the test cable 132 is not in use, so as to reduce the impact of dust, moisture or external impact on the test cable 132 and the detection interface.

[0047] An adaptive fixing assembly is provided on the rear side of the diagnostic equipment body 100. The adaptive fixing assembly includes a metal bracket 171, a clamp 172, an annular airbag 173, and an air pump 174. The metal bracket 171 is fixed to the rear side of the diagnostic equipment body 100, and the clamp 172 is connected to the metal bracket 171 via a damping shaft. The damping shaft allows the diagnostic equipment body 100 to rotate relative to the clamp 172 and maintain a predetermined angle, thereby facilitating maintenance personnel to adjust the viewing angle of the display 150 according to the site location.

[0048] The clamp 172 includes a first clamp body and a second clamp body that are hinged together. The ends of the first clamp body and the second clamp body away from the hinge end are connected by a locking bolt. The locking end of the clamp 172 is provided with multiple adjusting holes arranged at intervals along the circumference of the clamp. The locking bolt passes through different adjusting holes to adjust the diameter of the clamp 172. The annular airbag 173 is fixed to the inner circumference of the clamp 172, and the inner circumference of the annular airbag 173 is provided with an elastic anti-slip layer. The air pump 174 is connected to the annular airbag 173 through an air pipe, and a deflation valve is provided on the air pipe.

[0049] In use, maintenance personnel open clamp 172, wrap clamp 172 around the outside of the air compressor pipeline or frame, and initially tighten it with locking bolts. Then, the air pump 174 is started to inflate the annular air bladder 173. After the annular air bladder 173 expands, it presses against the outer wall of the air compressor pipeline, thus stably fixing the main body 100 of the diagnostic equipment onto the pipeline. After the test is completed, the gas inside the annular air bladder 173 is released through the vent valve, and clamp 172 can be removed from the pipeline. Because the annular air bladder 173 can adapt to the outer diameter of the pipeline, this structure can accommodate air compressor pipelines of different diameters and reduce slippage or damage caused by direct clamping with rigid clamps.

[0050] As an extended implementation, a printer 160 may be installed on the rear side of the diagnostic device body 100. The printer 160 is electrically connected to the processor 110, and the processor 110 can control the printer 160 to output a test result report, which includes the test items, test values, fault codes, fault causes, and maintenance prompts.

[0051] As another extended implementation, the diagnostic device body 100 includes a wireless communication module 112. The wireless communication module 112 can be a Bluetooth module, a Wi-Fi module, a 4G communication module, or a 5G communication module. The processor 110 can control the multi-channel detection and simulation module 120 to perform at least one of the following operations based on the detection commands received from the wireless communication module 112: detection channel selection, detection initiation, analog signal output, detection data reading, and historical record uploading. Maintenance personnel can also read the detection results or export historical diagnostic records via a mobile terminal.

[0052] The working process of this invention is as follows: The maintenance personnel carried the diagnostic equipment body 100 to the air compressor site and selected whether to use the self-adaptive fixing component based on the site space and pipeline location. When equipment fixing was required, the clamp 172 was opened and placed on the air compressor pipeline, and initially fixed with the locking bolts. Then, the air pump 174 inflated the annular air bag 173, causing the annular air bag 173 to press against the outer wall of the pipeline. Subsequently, the damping shaft was adjusted so that the display 150 was oriented at an angle that facilitated observation.

[0053] The maintenance personnel open the cover 133 at the test cable storage chamber 130, pull out the test cable 132 from the reel 131, and connect the test cable 132 to the air compressor's test terminal, sensor interface, or controller communication interface. The test item is selected via the control switch 141 or display 150. The processor 110 controls the corresponding test module to operate, acquiring voltage, current, resistance, pressure sensing signals, temperature sensing signals, or communication bus signals.

[0054] The processor 110 compares the detected value with the fault diagnosis mapping table pre-stored in the data storage unit 111. When the detected value is within the normal threshold range, the display 150 shows that the corresponding item is normal; when the detected value exceeds the threshold range or an abnormal signal state occurs, the processor 110 generates a corresponding fault code and displays the fault cause and maintenance prompt information on the display 150. If a printer 160 is provided, the processor 110 can also control the printer 160 to output a diagnostic report. If a wireless communication module 112 is provided, the processor 110 can send the test results to a mobile terminal or a remote management platform.

[0055] Through the above structure, the present invention not only realizes the centralized detection and simulation of air compressor electrical parameters, pressure sensing signals and temperature sensing signals, but also realizes the centralized storage of the detection line 132 through the detection line storage cavity 130 and the winding wheel 131, and solves the problem of unstable placement of field equipment through the adaptive fixing component, thereby improving the field adaptability and operational efficiency of air compressor fault diagnosis.

[0056] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
