Embodiment 1

[0063] In this embodiment, the signal characteristic of the input signal adopts the signal duty cycle Duty. After the multiple CVM controllers are powered on, the bus transmission is turned off. By default, the output terminal outputs a signal with a duty cycle of 100%.

[0064] When the signal characteristic is the signal duty cycle, obtaining the number of the CVM controller based on a preset signal characteristic variation rule, and generating an output signal and inputting it to an adjacent CVM controller includes the following steps:

[0065] 11) When the signal duty cycle of the input signal is 0%, set the count value to 0, the number of the CVM controller is the reference number, and the duty cycle of the output signal=reference duty cycle+interval duty cycle * count value.

[0066] 12) When the signal duty cycle of the input signal is not 0%, set the count value=(the duty cycle of the input signal-reference duty cycle) / interval duty cycle, the number of the CVM contr...

Embodiment 2

[0070] In this embodiment, the signal characteristic of the input signal adopts the duty cycle within the cycle.

[0071] When the signal characteristic is the number of pulses in a cycle, obtaining the number of the CVM controller based on a preset signal characteristic change rule, and generating an output signal and inputting it to an adjacent CVM controller includes the following steps:

[0072] 21) When the number of pulses in the cycle of the input signal is 0, the number of the CVM controller is set as the reference number, and the number of pulses in the cycle of the output signal is 1.

[0073] 22) When the number of pulses in the cycle of the input signal is n and n is not equal to 0, set the number of the CVM controller = reference number + n, the number of pulses in the cycle of the output signal = reference number +n+1.

[0074] like Figure 4 As shown, there is no input signal at the input terminal of CVM1, that is, there is no pulse in the period T, the number...

Embodiment 3

[0076] In this embodiment, the signal characteristic of the input signal adopts a voltage value.

[0077] When the signal characteristic is a voltage value, obtaining the number of the CVM controller based on a preset signal characteristic change rule, and generating an output signal and inputting it to an adjacent CVM controller includes the following steps:

[0078] 31) When the voltage value of the input signal is 0, the number of the CVM controller is set as the reference number, and the voltage value of the output signal is the reference voltage.

[0079] 32) When the voltage value of the input signal is not 0, set the count value=(the voltage value of the input signal−reference voltage) / interval voltage+1, the number of the CVM controller=reference number+count value, The voltage value of the output signal=reference voltage+interval voltage*count value; wherein, the reference voltage and the interval voltage are user-defined values.

[0080] like Figure 5 As shown, th...

Description

technical field [0001] The present invention relates to the technical field of fuel cells, in particular to a fuel cell voltage monitoring controller and an automatic numbering method, system and storage medium thereof. Background technique [0002] The fuel cell voltage monitoring (CVM) controller is used to monitor the single chip voltage of the fuel cell and perform real-time undervoltage and reverse polarity alarms. However, due to the increase in the total power requirement of the fuel cell stack and the increase in the number of single cells of the stack, the problem that a single stack needs multiple CVM controllers for voltage sampling and monitoring. [0003] Each single cell monitored by the CVM controller has a strongly correlated positional correspondence with the stack. At the same time, when the CVM controller has the bus communication function, its bus message ID is not allowed to be repeated. Therefore, multiple CVM controllers need to distinguish channels ...
