Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen fuel cells, and specifically to a hydrogen fuel cell data acquisition system. Background Art

[0002] Hydrogen has advantages such as being clean and efficient, and its calorific value of combustion is the highest among all fossil fuels, chemical fuels, and biological fuels except nuclear fuels. These advantages make hydrogen one of the key technologies for solving global energy shortages and environmental pollution problems. A fuel cell using hydrogen as the main fuel has advantages such as zero emissions, low noise, high energy conversion efficiency, and fast startup, and is very suitable for use as power for vehicles, ships, etc.

[0003] A hydrogen fuel cell is similar to an ordinary rechargeable battery in structure. However, the difference is that the fuel of a hydrogen fuel cell is supplied externally, and the output power is determined by the size of the fuel cell and has nothing to do with the amount of stored energy. If the stored energy needs to be increased, only the reaction substances and their storage devices need to be increased, without increasing the energy conversion device. This is the advantage of a hydrogen fuel cell system compared to a general battery. And after the reaction substances in the hydrogen fuel cell are used up, there is no need to replace the fuel cell, only the reaction substances need to be replenished. As long as the fuel is continuously supplied, the system can keep working without the need for long-term "charging". Hydrogen fuel cells are usually used to form a hybrid power system with a diesel generator or directly used in an auxiliary power system to work.

[0004] The battery management system of a hydrogen fuel cell must monitor the voltage value, current value, and temperature value of each battery cell in real time in order to achieve functions such as internal resistance estimation, humidity estimation, and stack protection of the battery cell. Therefore, real-time voltage, current, and temperature acquisition is one of the essential functions of a fuel cell inspection system.

[0005] Traditional battery voltage monitoring systems can only achieve the acquisition of the voltage of a single battery cell. However, only collecting the voltage of a single battery cell cannot effectively reflect the actual state of a hydrogen fuel cell. The existing voltage acquisition system collects the voltage through a voltage sensor, converts it into a digital signal through an AD conversion device and transmits it to a slave microcontroller, and then the slave microcontroller transmits the centrally collected voltage data to the main controller via a bus for the main controller to analyze and judge the state of the hydrogen fuel cell. As a result, the overall volume of the system is too large and it occupies a large space. Summary of the Invention

[0006] The purpose of the present invention is to provide a hydrogen fuel cell data acquisition system to solve the problems raised in the above background art.

[0007] To achieve the above object, the present invention provides the following technical solution: A hydrogen fuel cell data acquisition system, including a main protection box, which is the main protection component in the system, effectively protecting the main controller and slave controllers located inside it. Moreover, the main protection box integrates the main controller and multiple slave controllers, with a high degree of simplification, a small overall volume of the system, small occupied space and easy installation. There are a main compartment and multiple partition compartments arranged inside the main protection box. A main extraction slot and sub-extraction slots are respectively snap-fitted inside the main compartment and the multiple partition compartments. The main controller is installed in the main extraction slot, and multiple slave controllers are installed in the sub-extraction slots. The main controller and slave controllers are respectively installed in the main extraction slot and sub-extraction slots. The main compartment and the main extraction slot further protect the main controller, and the partition compartment and the sub-extraction slot further protect the slave controllers. The overall system is firm and highly integrated, and the extraction slot is convenient to be pulled out from the compartment, facilitating operations such as maintenance, replacement, and installation. Among them, multiple slave controllers are respectively used to collect voltage data, current data, and temperature data of the hydrogen fuel cell. The main controller and multiple slave controllers are respectively connected by wireless communication, and multiple slave controllers are connected by wireless communication to synchronize the acquisition time. The main controller sends a working signal to multiple slave controllers. After receiving the working signal, multiple slave controllers communicate with each other to determine the sampling time, and then respectively perform their own data acquisition work simultaneously. After the sampling is completed, multiple slave controllers send their respective data to the main controller. The slave controller for collecting voltage includes a voltage acquisition module, which is electrically connected to the hydrogen fuel cell through a signal processing unit. The voltage acquisition module is used to collect the voltage of the hydrogen fuel cell; a single-chip microcomputer, which is electrically connected to the voltage acquisition module; a wireless transmission module, which is electrically connected to the single-chip microcomputer and wirelessly communicates with the main controller. The slave controllers for collecting current and temperature have the same acquisition principle as the slave controller for collecting voltage.

[0014] Preferably, the upper wall and the lower wall of the main protection box are respectively fixedly connected with a reinforcement net, and the reinforcement net is composed of ribs staggered horizontally and vertically. The setting of the reinforcement net increases the impact strength of the upper wall and the lower wall of the main protection box, and improves the overall robustness of the system.
