Detection device of vehicle-mounted signal collector

Abstract

The invention belongs to the technical field of detection of a vehicle-mounted control box, and discloses a detection device of a vehicle-mounted signal collector, which comprises a detection module and a test computer, wherein the test computer comprises an upper computer, and the detection module comprises a control circuit board and a power supply module; the detection module receives a detection command issued by the upper computer through bus communication, and the detection module provides a power supply with protection and a test signal for the detected signal collector according to thedetection command; the detection module detects the state of the signal collector, converts the state information and the test result fed back by the tested signal collector into bus communication data, and sends the bus communication data to a bus network and transmitting the bus communication data to the upper computer; the upper computer displays the state information and the test result in the form of graphs, numbers and indicator lights. The detection device has the advantages of good protection measure, simple detection and high efficiency; the detection device can be operated by one person, thereby ensuring that the electrical part of the product meets the functional requirements, and reducing the production cost effectively.

Description

technical field [0001] The invention belongs to the technical field of vehicle control box detection, and relates to a vehicle signal collector detection device. Background technique [0002] After the vehicle-mounted signal collector is produced and assembled, its function needs to be tested. The current practice is to use a signal generator, DC power supply, multimeter, computer and software for detection, operate the signal generator to simulate the sensor input frequency signal, voltage signal, use the DC power supply to simulate the sensor to input high and low level signals, and use the computer and software to simulate the input control Command and view the output results, and use a multimeter to measure whether there is voltage output at the corresponding output port. It requires the cooperation of two professionals to complete the operation. The detection efficiency is low and it takes a long time. At the same time, there are hidden dangers of live plugging and unpl...

The current practice is to use a signal generator, DC power supply, multimeter, computer and software for detection, operate the signal generator to simulate the sensor input frequency signal, voltage signal, use the DC power supply to simulate the sensor to input high and low level signals, and use the computer and software to simulate the input control Command and view the output results, and use a multimeter to measure whether there is voltage output at the corresponding output port. It requires the cooperation of two professionals to complete the operation. The detection efficiency is low and it takes a long time. At the same time, there are hidden dangers of live plugging and unplugging cables, and it is very easy to collect the measured signals. Devices cause irreparable damage, increasing production risks and costs
