Abstract
A gear detection device with optical fiber sensors comprises the four pairs of opposite type optical fiber sensors, which are respectively mounted around an automotive gear lever, each optical fiber sensor consists of a transmitting end and a receiving end, and the receiving ends of the four optical fiber sensors are respectively connected with a vehicle-mounted computer through a data acquisition module. According to the signal which is obtained when different optical fiber sensors are blocked by the gear lever in the process of gear shifting, the vehicle-mounted computer judges the position of the gear lever in order to detect the shifted gear. Because the position change is little in the process of gear shifting, the mounting space is small; since the optical fiber sensor is characterized by small sizes of the transmitting end and the receiving end and high resolution and can accurately measure 1mm to 2mm of objects, the mounting is simple, and the measurement is accurate.
Description
Technical field
The utility model relates to a kind of Fibre Optical Sensor gear pick-up unit, belongs to vehicle driver place driving efficiency examination device technical field.
Background technology
Develop rapidly along with China's automobile cause, owning amount rapidly increases, the people of study car steering technical ability is more and more, and is also more and more higher to the examination request of car steering skill, and the method for the artificial examination of the usefulness in past can not satisfy present driving efficiency examination request.In the process of vehicle driver place driving efficiency examination, " hundred a meters plus-minus retainings " project is arranged, to in driving procedure, need gear seted out and carry out detection of dynamic, some producer adds sensor to finish the detection of gear dislodging retaining in the wheel box of vehicle, this mode is installed complexity, destroy car construction, maintenance difficulty is big.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of installation simple, need not dismantle vehicle, does not destroy car construction, Fibre Optical Sensor gear pick-up unit easy to maintenance.
A kind of Fibre Optical Sensor gear pick-up unit, comprise four pairs of correlation Fibre Optical Sensors, be installed in automobile respectively and put into gear around the pin, every pair of Fibre Optical Sensor comprises a transmitting terminal and a receiving end, and the receiving end of four Fibre Optical Sensors is connected with vehicle-mounted computer by the data acquisition template respectively.
Described Fibre Optical Sensor is the correlation type, and the correlation distance is greater than 250mm.
32 light of described data acquisition template usb bus separate the pass template, model: AMUSB-7206.
Described vehicle-mounted computer Industrial PC Computer, model: CARPCINTEL ATOM Dual CORE 1.6G.
Principle of work:
In the process of retaining of seting out, block the signal that different Fibre Optical Sensors obtains according to pin and judge that by vehicle-mounted computer thereby the position of pin detects the retaining gear of seting out.Pin blocks 1, No. 2 Fibre Optical Sensor simultaneously and is judged to be 1 retaining; Block 1, No. 4 Fibre Optical Sensor simultaneously and be judged to be 2 retainings; Only block No. 2 Fibre Optical Sensors and be judged to be 3 retainings; Only block No. 4 Fibre Optical Sensors and be judged to be 4 retainings; Block 2, No. 3 Fibre Optical Sensors simultaneously and be judged to be 5 retainings.
Because change in location is less when gear is seted out retaining, installing space is also less, has utilized Fibre Optical Sensor emitting and receiving head volume little, and the characteristics that resolution is high (can accurately measure the object of 1-2mm) are accomplished to install simple, measure accurately.
