Example one
In order to solve the technical problems in the prior art, an embodiment of the present invention provides a monitoring device for a hydrogen fuel standby power supply, where the monitoring device for a hydrogen fuel standby power supply is applied to a rail transit hydrogen fuel train.

Wherein, each sampling module 12 and the output module 11 are respectively connected with the monitoring module 10.
In practical applications, when one sampling module 12 of at least two redundantly designed sampling modules 12 is in an operating state, the other sampling modules 12 are in a standby state. The sampling module 12 is in an operating state and is used for collecting operating parameters of the hydrogen fuel standby power supply and sending the collected operating parameters of the hydrogen fuel standby power supply to the monitoring module 10, and the monitoring module 10 determines regulation and control information of the hydrogen fuel standby power supply according to the operating parameters of the hydrogen fuel standby power supply and regulates and controls the hydrogen fuel standby power supply according to the regulation and control information. In addition, the monitoring module 10 may also send the operation parameters of the hydrogen fuel standby power supply to a train network system of the rail transit hydrogen fuel train through the output module 11, or receive relevant data from the train network system of the rail transit hydrogen fuel train, for example, a control instruction, an upgrade data packet, and the like sent by the train network system of the rail transit hydrogen fuel train.
In this embodiment, since the most important part of the efficient application of the hydrogen fuel backup power supply is to provide hydrogen gas with sufficient pressure to meet the requirement of the hydrogen fuel backup power supply, it is important how to monitor and monitor the state of the hydrogen storage device, in this embodiment, the operation parameter of the hydrogen fuel backup power supply preferably includes at least one of the pipeline pressure of the hydrogen storage device in the hydrogen fuel backup power supply, the temperature of the hydrogen storage device, and the hydrogen leakage information of the hydrogen storage device, but in practical application, the operation parameter is not limited to the above operation parameter, and for example, the relevant parameter of the fuel cell stack may also be included. Correspondingly, each acquisition module preferably comprises at least one of a line pressure sensor, a temperature sensor and a gas sensor.
In a specific implementation process, data interaction is performed between the monitoring device and the sampling module 12 in the running state, if the time length for which the monitoring device does not receive the running parameters of the hydrogen fuel standby power source sent by the sampling module 12 in the running state reaches a preset time length, it can be determined that the sampling module 12 in the running state fails, at this time, one sampling module 12 can be selected from the sampling modules 12 in the standby state, and the selected sampling module 12 is controlled to be switched to the running state to replace the original sampling module 12 in the running state, so that the running parameters of the hydrogen fuel standby power source are continuously collected, and therefore real-time monitoring of the hydrogen fuel standby power source is guaranteed.
According to the monitoring device for the hydrogen fuel standby power supply, at least two sampling modules 12 which are designed in a redundant manner are designed, the monitoring module 10 is used for monitoring the sampling modules 12 in the running state in real time, and when the sampling modules 12 in the running state are found to be in fault, one sampling module 12 in the sampling modules 12 in the standby state is selected to be switched to the running state, so that the running parameters of the hydrogen fuel standby power supply can be collected normally, and the hydrogen fuel standby power supply can be monitored uninterruptedly. By adopting the technical scheme of the invention, the reliability of monitoring the hydrogen fuel standby power supply can be improved.

In this embodiment, the microprocessor unit 101 in the running state is configured to control one sampling module 12 of the sampling modules 12 in the standby state to switch to the running state if it is monitored that the sampling module 12 in the running state fails; and the microprocessor unit 101 in the standby state is used for switching to the running state if the microprocessor unit 101 in the running state is monitored to have a fault.
Specifically, mutual monitoring can be realized between the microprocessor unit 101 in the running state and the microprocessor unit 101 in the standby state through a watchdog, so that if the microprocessor unit 101 in the running state fails, the microprocessor unit 101 in the standby state can be switched to the running state, so that the microprocessor unit 101 in the running state is taken over, the monitoring device for the hydrogen fuel standby power supply is continuously completed, and the reliability of monitoring the hydrogen fuel standby power supply is further improved.
In practical applications, the output module 11 in this embodiment may include a communication conversion unit, and each microprocessor unit 101 accesses the train network system of the rail transit hydrogen fuel train through the communication conversion unit. However, since it is necessary to add an additional communication conversion unit, which has a high cost and a poor communication rate and communication reliability, as shown in fig. 2, the output module 11 of the embodiment is preferably at least one of an ethernet circuit, a Multifunction Vehicle Bus (MVB) communication circuit, and a Controller Area Network (CAN) communication circuit. In this way, the output module 11 can be directly connected to the train network system of the rail transit hydrogen fuel train, thereby improving the communication speed and the communication reliability.
It should be noted that the output module 11 in this embodiment may also be implemented by using a redundancy design architecture, so as to further improve the reliability of monitoring the hydrogen fuel standby power supply.

In a specific implementation process, the modules are preferably arranged in an integrated mode, so that the integration level is high, the performance is excellent, the occupied volume is small, and the cost is low.
