Embodiment 1

[0027] see figure 1 , the operating method of the present invention is as follows:

[0028] (1) The signal from the signal input terminal 600 enters the vehicle speed / rotational speed sensor signal acquisition module 100, the vehicle speed / rotational speed sensor signal acquisition module 100 is responsible for collecting the signal, the signal from the ratio adjustment terminal 800 enters the A / D sampling module 200, the A / D The sampling module 200 is used for adjusting the angle ratio of the output signal of the proportional adjustment terminal 800 .

[0029] (2) The signal processed by the vehicle speed / rotational speed sensor signal acquisition module 100 and the A / D sampling module 200 enters the calculation module 300 .

[0030] (3) The computing module 300 sends the signal to the stepping motor control module 400 after processing, and displays it on the driving stepping motor 700 after being processed by the stepping motor control module 400 .

Embodiment 2

[0032] see figure 1 , another method of operation of the present invention is as follows:

[0033] (1) The signal from the signal input terminal 600 enters the vehicle speed / rotational speed sensor signal acquisition module 100, the vehicle speed / rotational speed sensor signal acquisition module 100 is responsible for collecting the signal, the signal from the ratio adjustment terminal 800 enters the A / D sampling module 200, the A / D The sampling module 200 is used for adjusting the angle ratio of the output signal of the proportional adjustment terminal 800 .

[0034] (2) The signal processed by the vehicle speed / rotational speed sensor signal acquisition module 100 and the A / D sampling module 200 enters the calculation module 300 .

[0035] (3) The operation module 300 processes signals, and some signals need to be processed multiple times. The power-on reset module 500 can make the operation module 300 automatically reset after processing the signals.

[0036] (4) The comp...

The special chip system is characterized by comprising a vehicle speed / rotation speed sensor signal acquiring module, a step motor control module, an operation module, an A / D (Analog to Digital) sampling module and an electrifying return module, wherein the vehicle speed / rotation speed sensor signal acquiring module and the A / D sampling module are both connected with the operation module; the step motor control module is connected with the operation module in series; and the electrifying return module is connected with the operation module. The special chip system has a simple structure and is convenient to use.

Description

technical field [0001] The invention relates to a chip system, in particular to an automotive electronic chip system, in particular to a special chip system for stepping motor rotation speed / speedometer. Background technique [0002] my country's automobile instrumentation has gone through three stages of development: mechanical, analog circuit electronic, and digital instrumentation. Electronic instruments composed of advanced sensors and display devices have begun to completely replace traditional electromechanical instruments, and now automotive instrumentation technology is developing towards digitalization. For example, the tachometer and speedometer driven by the traditional dedicated chip are gradually replaced by the tachometer and speedometer of the single-chip microcomputer and stepper motor. [0003] According to the existing technology, most of the tachometers and speedometers adopt the following three modes: (1) The traditional moving magnet meter that directly...
