system. The no-parking weighing and charging
system comprises a CPU (
Central Processing Unit) module, a weighing
system, a tire recognizer, a car type recognizer, a camera, a charging computer, a
display board and an audible and visual alarm, wherein the weighing system, the tire recognizer, the car type recognizer, the camera, the charging computer, the
display board and the audible and visual alarm are connected with the CPU module; the charging computer is connected with a printing
machine; the weighing system comprises an SCM (
Single Chip Microcomputer), a
crystal oscillation circuit, a reset circuit and a
serial communication circuit, the
crystal oscillation circuit, the reset circuit and the
serial communication circuit are connected with the SCM, the input end of the SCM is connected with a
signal conditioning circuit module, the
signal conditioning circuit module is formed by an amplification circuit module, a filter circuit module and an A / D (Analog to Digital) conversion circuit which are connected in sequence, the input end of the amplification circuit module is connected with a weighing sensor, the output end of the SCM is connected with an LCD (
Liquid Crystal Display) screen, and the
serial communication circuit is connected with the CPU module. According to the no-parking weighing and charging system disclosed by the invention, the structure is simple, weighing and charging can be realized under a no-parking situation, the use and the operation are convenient, the working reliability and the stability are high, the practicability is high, the using effect is good, and the promotion and the use are convenient.
