Abstract
Description
Technical Field
[0001] This invention relates to the field of display and control technology, specifically to a wide-range, stable, and interference-resistant display and control device adapted to special vehicles. Background Technology
[0002] Special vehicles often need to operate in environments with high or low temperatures, low air pressure, and strong electromagnetic interference. During operation, it is necessary to monitor the working status of the vehicle's sensors in real time and display the data output of each sensor, such as pressure sensors, oil temperature sensors, bracket displacement, operating procedures, alarm information, etc. Based on the displayed information, the process status and fault points can be judged in a timely and accurate manner.
[0003] To ensure that special vehicles can operate normally in environments with high temperature, low temperature, low air pressure and strong electromagnetic interference, it is necessary to provide a device that can still display and control normally in such environments. Summary of the Invention
[0004] To address the display and control needs of special vehicles, this invention develops a wide-temperature, anti-interference display and control device. The circuit board implements DC-DC power conversion, power-off retention, voltage monitoring, CAN bus data parsing, temperature acquisition, and display screen heating control functions. Under low-temperature conditions, the display screen temperature is adjusted by controlling the heating glass, shortening the low-temperature start-up time of the display screen. The device employs a reasonable layout and installation method to ensure internal shielding and sealing of the cavity, and waterproof and ventilated holes ensure consistent pressure difference between the inside and outside of the cavity, reducing component failures caused by pressure differences.
[0005] The purpose of this invention is to provide a wide-temperature, anti-interference display and control device suitable for special vehicles, comprising a housing 1, a shielding glass 2, a shielding glass sealing gasket 3, a shielding glass pressure plate 4, a conductive sealing gasket 5, a display screen 6, a connecting post 7, a circuit board 8, a top cover 9, a waterproof and breathable membrane 10, a power supply interface 11, a CAN communication interface 12, a CAN communication interface 13, and a software upgrade interface 14.
[0006] The upper cover plate (9) has grooves on both sides to ensure the spacing between the circuit board (8) and the upper cover plate (9), and the display screen (6) and the circuit board (8) are fixed by the grooves of the upper cover plate (9).
[0007] The upper cover plate (9) is provided with a lower groove for installing the power supply interface (11), CAN communication interface (12), CAN communication interface (13), and software upgrade interface (14).
[0008] A temperature sensor is located on the inner side of the lower right corner of the display screen (6). The temperature value collected by the temperature sensor is sent to the circuit board (8) through the inter-board connector between the display screen (6) and the circuit board (8).
[0009] The display screen (6) is equipped with heated glass. The circuit board (8) judges the collected temperature value. When the temperature value is less than the set threshold, the circuit board (8) turns on the heated glass on the surface of the display screen (6) to raise the temperature and shorten the low temperature start-up time of the display screen.
[0010] The beneficial effects of this invention are:
[0011] This invention provides a wide-temperature, anti-interference display and control device; it can shorten the startup time in low-temperature conditions, has excellent anti-electromagnetic interference capabilities, and has two dual-redundant CAN interfaces to parse vehicle CAN signals and display various vehicle information.
