Description
Technical field
The utility model relates to a kind of driving path examination vehicle travelling state pick-up unit.
Background technology
At present domestic in driver's real road examination process, adopt mode and the artificial judge mode of video Real Time Monitoring in the blocked road more, finish the examination to driver's driving efficiency on real road.Because sealing examination road does not have the complex environment that exists in the real road, thereby can't examine in the driving efficiency under the complex environment the driver.In order to examine the driving efficiency of driver in real road, just must solve the weak point of original blocked road real-time monitoring system.Because former supervisory system is not high at communication distance weak point, narrow bandwidth, transmission stability, the information of road surface acquisition means is not enough and outdoorly continue the problems such as independently-powered, can't finish real road collection and the data of the road conditions relevant information of taking an examination are transmitted task in real time.
Summary of the invention
In order to overcome the defective of prior art, the utility model provides a kind of driving path examination vehicle travelling state pick-up unit of energy stable transfer, realizes the collection to information in subject three road examination systems.
The technical solution of the utility model is: driving path examination vehicle travelling state pick-up unit, its difference is: it comprises vehicle speed sensor, speed probe, the waveform sorting module, the photoelectric coupling module, steering indicating light, optoelectronic switch, the photoelectric coupling module, the MCU chip, power transfer module, communication module, industrial computer, vehicle speed sensor, speed probe imports signal into the waveform sorting module respectively successively, the photoelectric coupling module enters the MCU chip again, steering indicating light, optoelectronic switch then with signal respectively by sending into the MCU chip after the photoelectric coupling module converts, power transfer module is to the MCU chip power supply, the MCU chip gathers the simulating signal from clutch coupling, and the MCU chip is crossed communication module with the data communication device that collects and is sent to industrial computer.
The utility model principle of work: power input voltage is processed backward MCU chip power supply through power transfer module.After the signal picker energising, the MCU chip is started working, and the pulse signal that vehicle speed sensor and speed probe produce is processed through chip through light-coupled isolation again, sends the data after calculating to industrial computer.The modulating signal such as steering indicating light and optoelectronic switch is digital quantity signal, as long as modulating signal changes, the MCU chip just can collect data.Clutch engagement signal is simulating signal, if clutch coupling has response, then the voltage of clutch coupling output changes, and the AD converter of chip internal will collect corresponding data, can obtain corresponding value by calculating.The MCU chip gathers a secondary data at set intervals, all data communication devices that collect is crossed communication module send to industrial computer, and industrial computer will show examinee's corresponding information of taking an examination.
The utility model power consumption is ultralow, and antijamming capability is strong.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Further specify the utility model embodiment below in conjunction with accompanying drawing.
Driving path examination vehicle travelling state pick-up unit, it comprises vehicle speed sensor, speed probe, the waveform sorting module, the photoelectric coupling module, steering indicating light, optoelectronic switch, the photoelectric coupling module, the MCU chip, power transfer module, communication module, industrial computer, vehicle speed sensor, speed probe imports signal into the waveform sorting module respectively successively, the photoelectric coupling module enters the MCU chip again, steering indicating light, optoelectronic switch then with signal respectively by sending into the MCU chip after the photoelectric coupling module converts, power transfer module is to the MCU chip power supply, the MCU chip gathers the simulating signal from clutch coupling, and the MCU chip is crossed communication module with the data communication device that collects and is sent to industrial computer.
Concrete, the MCU chip can adopt the MSP430F449 chip, and power input voltage is 5v, processes obtaining 3.3v voltage through power transfer module, for the MSP430F449 normal operation.After the signal picker energising, the MSP430F449 chip is started working, and the pulse signal that vehicle speed sensor and speed probe produce is processed through chip through light-coupled isolation again, sends the data after calculating to industrial computer.The modulating signal such as steering indicating light and optoelectronic switch is digital quantity signal, as long as modulating signal changes, chip just can collect data.Clutch engagement signal is simulating signal, if clutch coupling has response, then the voltage of clutch coupling output changes, and the AD converter of chip internal will collect corresponding data, can obtain corresponding value by calculating.Chip gathers a secondary data every 300ms, all data communication devices that collect is crossed communication module send to industrial computer, and industrial computer will show examinee's corresponding information of taking an examination.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
