Technical Field

[0001] The utility model belongs to the technical field of hydrogen energy, and in particular relates to a fuel cell air compressor test and monitoring system based on the Internet of Things. Background Art

[0002] To overcome over-reliance on fossil fuels and improve and reduce environmental pollution, the hydrogen energy and fuel cell industries are rapidly developing. Because hydrogen fuel cells are primarily used in vehicles and ships, they place high demands on performance and reliability. Therefore, air compressors, as core components of hydrogen fuel cells, require extensive performance and durability testing to verify their performance. Current long-term testing requires on-site monitoring by test personnel, which undoubtedly incurs significant labor and time costs. Summary of the Invention

[0005] The IoT component consists of a display terminal, a cloud platform server, a data acquisition gateway, and a 4G cabinet antenna. The data acquisition gateway regularly uploads the compressor system's pressure, temperature, flow rate, and vibration acceleration test process data collected by the test monitoring system controller to the cloud platform server. It also regularly updates the start, stop, and compressor speed control commands issued by the cloud platform server and transmits them back to the test monitoring system controller. Operators access the cloud platform server through the display terminal to monitor the fuel cell compressor's process parameters during testing and issue control commands.

[0009] The signal acquisition and transmission module receives analog signals from the temperature sensor, pressure sensor, and flow sensor on the test bench, converts them into digital signals of the temperature, pressure, and flow of the corresponding air compressor and air compressor process pipeline, and then sends them to the test monitoring system controller for calculation.

[0010] The signal acquisition and transmission module receives the digital signals of valve opening and water pump speed from the test monitoring system controller, converts them into corresponding analog signals, and sends them to the opening valve and water pump.

[0011] The acceleration sensor on the test bench uses a communication connection method to upload the vibration acceleration data of the air compressor to the test monitoring system controller, and the communication uses the Modbus communication protocol.

[0016] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0017] Therefore, the detailed description of the embodiments of the present invention provided in the following figures is not intended to limit the scope of the claimed invention but is merely representative of selected embodiments of the present invention.

[0018] like Figure 1 As shown, a fuel cell air compressor test and monitoring system based on the Internet of Things includes an Internet of Things part, a test system control part and field equipment.

[0019] The IoT component consists of a display terminal, cloud platform server, data acquisition gateway, and 4G cabinet antenna. The data acquisition gateway regularly uploads the compressor system's pressure, temperature, flow rate, and vibration acceleration test process data collected by the test monitoring system controller to the cloud platform server via the 4G cabinet antenna. It also regularly updates the start, stop, and compressor speed control commands issued by the cloud platform server and transmits them back to the test monitoring system controller. Operators access the cloud platform server through the display terminal to monitor the fuel cell compressor's process parameters during testing and issue control commands.

[0020] The test system control section includes a test monitoring system controller and a signal acquisition and transmission module. The signal acquisition and transmission module receives analog signals from the temperature sensor, pressure sensor, and flow sensor on the test bench, converts them into digital signals of the temperature, pressure, and flow of the corresponding air compressor and air compressor process pipeline, and then sends them to the test monitoring system controller for calculation. At the same time, when the controller issues an instruction, the signal acquisition and transmission module receives digital signals of valve opening and water pump speed from the test monitoring system controller, converts them into corresponding analog signals, and sends them to the opening valve and water pump. As for the acceleration sensor, the Modbus communication protocol communication connection method is used to upload the vibration acceleration data of the air compressor to the test monitoring system controller.

[0021] The on-site equipment is installed on the fuel cell air compressor test bench. It includes the compressor inlet temperature sensor, compressor outlet temperature sensor, pipeline outlet temperature sensor, compressor inlet pressure sensor, compressor outlet pressure sensor, pipeline outlet pressure sensor, coolant pressure sensor, gas outlet flow sensor, coolant flow sensor, compressor vibration acceleration sensor, gas outlet opening valve, water pump, and compressor driver. After the sensors collect data, the data is converted into digital signals by the signal acquisition and transmission module and then sent to the test monitoring system controller for further processing and analysis. This data includes key compressor parameters such as inlet temperature, outlet temperature, pipeline temperature, inlet pressure, outlet pressure, pipeline pressure, as well as coolant pressure, gas outlet flow, coolant flow, and compressor vibration acceleration. Upon receiving signals from the test monitoring system controller, the compressor driver uses a communication conversion module to convert the Ethernet protocol on the monitoring system controller to the CANbus protocol on the compressor driver to control various operating parameters and performance of the compressor. Once the monitoring system controller sends commands and setpoints via Ethernet, the communication conversion module converts this information into CANbus protocol and transmits it to the compressor driver. Upon receiving the CANbus command, the compressor driver adjusts the compressor's speed, operating pressure, and other operating parameters based on the setpoints, ensuring stable operation within the specified operating conditions.
