Problems solved by technology

The emergence and application of these technologies have also brought great difficulties to the maintenance of automobiles. For example, when repairing the engine ignition system, one person must start the ignition in the car, and the other person must observe the sparks outside. This maintenance method is not safe. And the efficiency is low, and the detection information is not accurate and reliable
It can be seen that the signal conditioning of the existing technology can no longer adapt to its development and application

Abstract

The invention relates to a signal input system of vehicle-mounted multimedia advertising entertainment interactive equipment, which comprises a taximeter, a taxi engine ignition sensor, a driver remote control switch and a signal input module, wherein the signal input module comprises a surge protection and signal filtering circuit, a signal conversion and amplification circuit, an analog / digital conversion circuit and a communication interface circuit; the signal conversion and amplification circuit is respectively connected with the surge protection and signal filtering circuit and the analog / digital conversion circuit; the communication interface circuit is respectively connected with the analog / digital conversion circuit and a central processor; and the taximeter, the taxi engine ignition sensor and the driver remote control switch are respectively connected with the surge protection and signal filtering circuit. The signal input system of the vehicle-mounted multimedia advertising entertainment interactive equipment has more stable, accurate and reliable conditioning for signals and also has a diagnostic function per se.

Description

technical field [0001] The invention relates to a signal input system, in particular to a signal input system of a vehicle-mounted multimedia advertising and entertainment interactive device. Background technique [0002] With the rapid development of science and technology, the proportion of high-tech in the automobile industry is also increasing. The engine ignition signal, meter signal, wheel speed signal, driver control signal, etc. in the car have been replaced by the original mechanical transmission. Sensors are transitioning to digitalization and are being replaced by Hall sensors and magnetic induction sensors. The emergence and application of these technologies have also brought great difficulties to the maintenance of automobiles. For example, when repairing the engine ignition system, one person must start the ignition in the car, and the other person must observe the sparks outside. This maintenance method is not safe. And the efficiency is low, and the detectio...
