Description

Technical Field

[0001] This invention belongs to the field of fuel cell technology, and in particular relates to a data acquisition device for a fuel cell system with remote wake-up and hibernation functions. Background Technology

[0002] Currently, fuel cell engines in the new energy industry are widely used in the automotive sector due to their zero-emission, long driving range, and rapid hydrogen refueling capabilities. In the era of intelligent technology, real-time data acquisition is beneficial for understanding, controlling, and predicting system status, enabling faster fault location and resolution. However, in existing fuel cell vehicles, obtaining on-site fuel cell system status information requires on-site startup and power-on for the data acquisition unit to function and acquire system data.

[0025] Fuel cell system: mainly refers to hydrogen fuel cell, including the entire fuel cell system including the stack, air system, hydrogen system, and cooling system, which can provide power for vehicles, ships, etc.

[0026] Data acquisition unit: Installed on the fuel cell system, it is used for real-time monitoring, acquisition, storage and remote transmission of fuel cell system data. Through data analysis, it can locate the cause of failure, understand the system's operating characteristics and predict future operating trends, and plan ahead and predict failures.

[0027] Sleep mode: The device is in a low-power state, which does not pose a threat of power depletion to batteries or other power-powered devices.

[0028] like Figure 1 As shown in the figure, this embodiment discloses a fuel cell system data acquisition device with remote wake-up and hibernation functions, including: an enable wake-up circuit, a control circuit, a data transmission circuit, and a wireless communication circuit. The output terminal of the enable wake-up circuit is electrically connected to the input terminal of the control circuit, and the data transmission circuit and the wireless communication circuit are both electrically connected to the control circuit.

[0029] Optional, such as Figure 2 As shown, the enable wake-up circuit includes a power management circuit, a diode D1, an OR gate circuit, and a Zener diode D2. The cathode of the diode D1 is electrically connected to the power management circuit, the cathode of the diode D1 is electrically connected to the cathode of the Zener diode D2, the anode of the Zener diode D2 is grounded, the output terminal of the OR gate circuit is electrically connected to the power management circuit, and the input terminal of the OR gate circuit is electrically connected to an external device. Figure 2 In the diagram, VBAT represents the external battery, IG and FILK represent external signals such as key signals, Vref represents the reference voltage, and CAN represents the bus.

[0030] Optionally, the power management circuit includes a 6.5V voltage regulator circuit.

[0031] Optionally, a storage circuit may also be included, which is electrically connected to the control circuit.

[0032] Optionally, it also includes a signal light display circuit, which is electrically connected to the output terminal of the control circuit.

[0033] Optionally, the control circuit includes an MCU chip.

[0034] Optionally, it also includes a power supply circuit, the output of which is electrically connected to the input of the enable / wake-up circuit.

[0035] Optionally, when the enable wake-up circuit receives a high-level signal or a low-level signal, it outputs a signal to the control circuit. The control circuit controls the data acquisition unit to collect the operating data of the fuel cell. When the high-level signal or low-level signal at the input of the enable wake-up circuit disappears, the data acquisition unit enters sleep mode.

[0036] Optionally, when the enable wake-up circuit receives a wake-up command sent by the user terminal, it outputs a signal to the control circuit, and the control circuit controls the data acquisition unit to collect the operating data of the fuel cell.

[0037] When the enable / wake-up circuit receives a sleep command sent by the user terminal, it outputs a signal to the control circuit, which then controls the data acquisition unit to enter sleep mode.

[0038] This embodiment also discloses a fuel cell data acquisition system, including a data acquisition device, a storage battery, a fuel cell, and a user terminal disclosed in this embodiment; the user terminal can be a mobile phone or a cloud platform, etc.

[0039] The battery is electrically connected to the data acquisition unit, the fuel cell is electrically connected to the data transmission circuit and the enable / wake-up circuit, and the user terminal is communicatively connected to the wireless communication circuit.

[0040] The data acquisition unit can operate in two ways: 1. When the fuel cell system is working or the ignition switch of the device installed in the vehicle is closed, the data acquisition unit is woken up via a high or low level signal transmission on the wiring harness. The data acquisition unit then begins normal operation, communicating with the fuel cell system, storing the collected data, and communicating wirelessly with a cloud-based app platform to acquire data from the fuel cell system. 2. When the fuel cell system is not working or the ignition switch of the device in the vehicle is open, the high or low level signal on the wiring harness disappears, and the data acquisition unit returns to sleep mode, i.e., standby or low-power mode. This mode avoids the need for the data acquisition unit to operate continuously, thus preventing energy waste and battery depletion.

[0041] 2. When the fuel cell system is not working or the key switch of the equipment installed in the vehicle is off, and there are no maintenance personnel or the driver is not present, the data acquisition unit cannot be woken up by high or low level signals on the wiring harness. In the event of a fuel cell system failure, the data acquisition unit can be woken up by sending a text message or making a phone call through a remote APP cloud platform, thereby enabling remote acquisition of fuel cell system data, facilitating data analysis, locating the cause of the failure, and solving the problem. After completing the data acquisition, the data acquisition unit can be notified to go into sleep mode, i.e., standby or low power mode, through a remote APP cloud platform or by sending a text message or making a phone call. This ensures that the data acquisition unit does not need to work all the time, does not waste power, and does not allow the battery to run out of power.

[0042] The data acquisition device implemented here can be remotely or wirelessly woken up and put into sleep mode anytime and anywhere, regardless of the absence of on-site personnel. In addition, this data acquisition device can also realize a sleep standby function, which can put the data acquisition into sleep mode at any time when the data acquisition device is not in use, thus saving energy.
