Abstract

The invention discloses a mileage pulse dual-signal switching device for a vehicle chassis. The mileage pulse dual-signal switching device comprises a box body (7) and further comprises an I / O (Input / Output) interface (1), a NOT gate A (2), a NOT gate B (3), a resistor R, a power supply (4), a filter capacitor C1, a low-frequency filter capacitor C2, a high-frequency filter capacitor C3, a printed board (5) and a cover plate (6), wherein the I / O interface (1) is connected with the input terminal of the power supply (4); the filter capacitor C1, the power supply (4), the low-frequency filter capacitor C2 and the high-frequency filter capacitor C3 are connected in parallel; the power supply (4) outputs a DC+5V electrical signal to power the NOT gate A (2) and the NOT gate B (3); the NOT gate B (3) outputs a pulse voltage signal; the pulse voltage signal is converted into a pulse current signal after passing through the resistor R; and the pulse current signal is output to the I / O interface (1), so as to provide both current and voltage to a vehicle-mounted inertial device. The mileage pulse dual-signal switching device has a simple structure and is easy to mount; and a vehicle instrument and the vehicle-mounted inertial device can work simultaneously.

Description

technical field [0001] The invention relates to a signal conversion device, in particular to a vehicle chassis mileage pulse dual-channel signal conversion device. Background technique [0002] The vehicle-mounted inertial device is commonly used in vehicles. When the vehicle-mounted inertial device is working, it needs to connect a pulse signal proportional to the rotation of the wheel. There is a mileage sensor on the chassis of the vehicle, which senses the rotation of the axle and outputs a pulse signal proportional to the rotation of the wheel. When the vehicle is moving, the sensor provides a pulse signal. The odometer receives the pulse signal from the sensor and is driven by the pulse signal current. The meter works, counts the pulse signal, and displays the mileage of the vehicle. When the vehicle-mounted inertial device is connected in parallel with the chassis odometer and connected to the pulse signal sent by the chassis sensor at the same time, since the curren...
