Problems solved by technology

The disadvantage of this kind of mechanical disc recorder is that the accuracy is too poor; Record the driving time and speed, and the rest such as the driver’s name, car number, date, and mileage must be filled in separately, which is prone to forgetting or making mistakes
The disadvantage of this kind of recorder is that it cannot immediately and completely print out the real speed curve and related information of the vehicle's actual running process for 24 hours, which is not conducive to complete collection and management

Abstract

The intelligent vehicle running record instrument for monitoring and managing motor vehicles consists of monochip computer, real-time clock circuit, memory, display and vehicle speed sensor and features a printing drive circuit connected to the computer and one dot printer for real-time record of vehicle speed vs time curve connected to the drive circuit. The printing drive circuit consists of five pairs of composite transistors and some peripheral elements and devices and the five pairs of composite transistors are connected to the dot printer. The instrument is used for dynamic monitor of vehicle 24 hr a day and print its speed curve for reference.

Description

Technical field: [0001] The invention relates to a monitoring and management device for vehicles. In particular, it relates to a tachograph for recording the operating conditions of a motor vehicle. Background technique: [0002] In order to strengthen the monitoring and management of motor vehicles and reduce the occurrence of accidents and violations of rules and regulations, it is common at home and abroad to install a driving recorder on the motor vehicle to record the speed and load of the motor vehicle during driving for future reference. One of the methods used. What is currently used abroad is a mechanical disk recorder, which uses polar coordinates to record, and uses the centrifugal force of the flexible shaft of the automobile odometer to drive the pointer to move on the disk to record the speed curve. The disadvantage of this kind of mechanical disc recorder is that the accuracy is too poor; Record the driving time and speed, and the rest such as the driver's ...
