Abstract

The invention discloses a vehicle-mounted CAN bus key panel and a control method of the vehicle-mounted CAN bus key panel. The vehicle-mounted CAN bus key panel comprises a silica gel face shell, a PCB and a plastic bottom shell, wherein the silica gel face shell is provided with a transparent silica gel key area and a black silica gel separation area; the PCB is provided with a key body and LED lamps; the key body and the LED lamps are connected with a CPU module through a CAN bus; the LED lamps comprise an LED indicator lamp and an LED background lamp; the key body is located below the transparent silica gel key area; the LED indicator lamp is located below the black silica gel separation area. A key and the indicator lamp are adopted to replace a mechanical switch, the key body and the LED lamps are connected with the CPU module through the CAN bus, and therefore the service life is prolonged greatly, wiring is simplified, and the size of the key panel is decreased; the black silica gel separation area is arranged above the LED indicator lamp to avoid light interference, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to a button panel and a control method thereof, in particular to a vehicle-mounted CAN bus button panel and a control method thereof. Background technique [0002] At present, the rocker switch and a controller are commonly used on construction machinery vehicles at home and abroad to realize the functional control of the equipment such as lighting, air conditioning, walking, and boom control. This control method brings several problems: [0003] 1) The cost is very high. Especially the controller is expensive due to the use of 2 parts. [0004] 2) The rocker switch used is a mechanical switch, which is a vulnerable part and generally has a service life of less than 100,000 times. [0005] 3) The physical space occupied by the rocker switch and the controller is very large, and there are many parts on the construction vehicle, and the original space is not enough, resulting in a very cramped cockpit. [0006] 4) Wiring is comp...
