Bus gearbox control device based on ARM microcontroller

Abstract

The invention discloses a bus gearbox control device based on an ARM microcontroller. The bus gearbox control device comprises an ARM microcontroller, a crystal oscillator circuit module, a reset circuit module, a SD card data storage circuit module, and a GPRS wireless communication module. The input end of the ARM microcontroller is connected with a clock circuit module, a key operation circuit module, and a signal conditioning circuit module. The signal conditioning circuit module is formed by an amplifying circuit module, a filtering circuit module, and an A/D conversion circuit module. The input end of the amplifying circuit module is connected with a temperature sensor, a fuel quantity transducer, an oil pressure sensor, and a vehicle speed sensor. The output end of the ARM microcontroller is connected with an LED display screen, a charging control circuit, a first flow valve, a second flow valve, and a relay. The device solves problems of gearbox early damage, clutch early damage, and transmission system early damage, so development of buses meets low carbon technology requirements, and the low carbon technology is suitable for urban development.

Description

technical field [0001] The invention belongs to the technical field of bus gearbox control, in particular to a bus gearbox control device based on an ARM microcontroller. Background technique [0002] The gearbox is one of the key components of the car, and it mainly has the following four functions: 1. Change the driving size of the car and the torque on the driving wheel of the car in a large range; 2. Realize reverse driving; 3. Realize neutral gear. If there is a fault in the gearbox, the car will have the following eight faults: 1. When the gear is engaged, it cannot enter the gear smoothly; 2. After the gear is engaged for more than 1 second, the brake is released, and the vehicle is weak and cannot start automatically; 3. The speed cannot be increased. OK, after reaching a certain speed, step on the accelerator, but the acceleration has no effect; 4. When the gearbox shifts, the gear cannot be disengaged; 5. The gearbox automatically disengages or disorderly; 6. After...

Problems solved by technology

The gearboxes used in current buses are mostly products of the 1990s, which are operated by the driver's technical ability, use changes frequently, and the general technical performance of automobiles is poor. The disadvantages of existence are: gearbox early damage , early damage to the clutch, early damage to the transmission system, affecting the quality of bus service, troublesome maintenance, high replacement costs, if not found and repaired in time, it is easy to cause major traffic accidents
