Abstract
The utility model provides an external pluggable fuel cell hand-held controller has realized monitoring fuel cell system running state as required to have the function of adjusting output voltage and operational mode.
Description
Technical Field
The utility model belongs to the fuel cell field, especially, a controller.
Background
Direct methanol fuel cells generally have two main application scenarios, one is an unattended scenario, and the other is a portable application scenario. The fuel cell designed for unattended scene application usually considers cost factors, a display screen for displaying the parameter states of the cell cannot be arranged on a system, the working mode cannot be changed according to the real-time environment state, so that the fuel cell fails, or the operating state of the fuel cell cannot be visually observed when a technician regularly overhauls, and inconvenience is brought to fault identification and overhaul. In a portable application scenario, the fuel cell is generally limited in size and weight, a display screen cannot be integrated in the system, and the problem that the states of various parameters of the fuel cell cannot be determined is also caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a fuel cell hand-held controller, which can realize the arbitrary plug connection of a fuel cell system, and can observe each operation parameter of the fuel cell under each application scene under the condition of controlling the cost, thereby conveniently positioning the fault and rapidly completing the maintenance; meanwhile, the working modes under different environments are switched, so that the efficiency and the service life of the fuel cell are improved; and the adjustment of the output voltage of the fuel cell can be realized to adapt to different loads.
The utility model provides a technical scheme that its technical problem adopted as follows:
a fuel cell handheld controller comprising: the LED display screen comprises a power supply, a controller circuit board, a key part, a screen display part and an LED display part; the controller circuit board controls the operation of the key part, the screen display part and the LED display part, and is connected with a serial port lead and used for being connected with a fuel cell main control board; the power supply supplies power to the controller circuit board, the key part, the screen display part and the LED display part.
Further, the controller circuit board comprises a main chip, and the main chip is preferably an STM32 single chip microcomputer.
Further, the LED display part comprises LED lamps capable of displaying at least 2 colors, and is used for displaying different signals. Preferably, 3 colors of LED lamps can be displayed or 3 single-color LED lamps are arranged, and according to the arrangement of the main chip of the controller, the green LED lamp is lighted to indicate normal operation, the yellow LED lamp is lighted to indicate to-be-maintained, and the red LED lamp is lighted to indicate fault.
Further, the key portion comprises at least 3 keys for selection of different parameters or modes. According to the setting of the main chip, the keys are divided into up, down and confirmation for the operation of the display screen interface.
Drawings
Fig. 1 is a schematic diagram of the connection of a handheld controller.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
A fuel cell handheld controller comprising: the LED display screen comprises a power supply, a controller circuit board, a key part, a screen display part and an LED display part; the controller circuit board main chip is an STM32 single chip microcomputer which controls the operation of the key part, the screen display part and the LED display part, and the controller circuit board is connected with a serial port lead and is used for being connected with a fuel cell main control board; the power supply supplies power to the controller circuit board, the key part, the screen display part and the LED display part.
The LED display part is an LED lamp capable of displaying 2 colors, and according to the setting of the main chip of the controller, the LED lamp is lighted up in green to indicate normal operation, and the LED lamp is lighted up in red to indicate abnormal operation.
The key part comprises 3 keys, and the keys are divided into up, down and confirmation according to the setting of the main chip and are used for the operation of a display screen interface.
When needing, will the utility model discloses a on the fuel cell system host computer was pegged graft to handheld controller, handheld controller main chip passed through serial ports communication with the fuel cell main control board, with some operational data transmission to controller circuit board of fuel cell, then main chip carries out data processing after shows the screen. The real-time data can be monitored, and the states of the output voltage, the current, the temperature and the like of the fuel cell can be observed. The specific fault alarm can be displayed together through the screen and the LED lamp, and meanwhile the main chip can adjust the appropriate output voltage to match different loads. In addition, the function mode selection can be performed through keys on the controller, such as: and correspondingly adjusting the correspondingly set operating parameters of each component in the fuel cell system host in a high-temperature, low-temperature and normal-temperature mode.
The utility model discloses the scheme can real-time supervision fuel cell system running state, can simple effectual troubleshooting trouble, removes the drawback that the host computer just can see data from. The functions of setting and adjusting the output voltage of the fuel cell, switching modes and the like are realized.
