Description

Technical Field

[0001] The invention relates to the technical field of motor vehicle exhaust remote sensing, in particular to a motor vehicle exhaust remote sensing simulation light blocking trigger device. Background Art

[0002] Traditional motor vehicle exhaust telemetry equipment cannot debug the light blocking trigger function offline. The existing technology cannot simulate in the laboratory that a car passes by and automatically trigger the exhaust gas detection equipment to start detection. Road testing consumes a lot of manpower, material resources and financial resources. Therefore, a device is needed that can simulate the automatic triggering of the exhaust gas detection equipment when a car passes by. Summary of the invention

[0003] The purpose of the present invention is to provide a motor vehicle exhaust remote sensing simulation light blocking triggering device to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A motor vehicle exhaust remote sensing simulation light-blocking trigger device comprises an equipment box, on the mutually symmetrical inner side walls of the equipment box are respectively fixedly provided with a light-transmitting tube 1 and a light-transmitting tube 2, a gap is provided at the ends of the light-transmitting tube 1 and the light-transmitting tube that are close to each other, a light-blocking plate is movably provided at the gap, a rotating electromagnet is provided below the light-transmitting tube 1, a rotating electromagnet mounting seat is fixedly provided on one side of the rotating electromagnet, the rotating electromagnet output shaft is rotatably connected to the rotating electromagnet mounting seat, and the light-blocking plate is fixedly connected to the rotating electromagnet output shaft.

[0006] Preferably, a counterweight is fixedly connected to the output shaft of the rotating electromagnet.

[0007] Preferably, a power supply is fixedly arranged in the equipment box, the power supply is electrically connected to a rotating electromagnet driver, and the rotating electromagnet driver is connected to the rotating electromagnet for communication control.

[0008] Preferably, the light blocking plate is provided with a light receiving groove on one side close to the light transmitting tube, a light receiver is fixedly arranged in the light receiving groove, a single-chip microcomputer is fixedly arranged on one side of the light receiver, and the light blocking plate is provided with a light emitting groove on one side away from the light transmitting tube, a light emitter is fixedly arranged in the light emitting groove, and both the light receiver and the light emitter are electrically connected to the single-chip microcomputer.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention drives a rotating light blocking plate to rotate by a rotating electromagnet, so that the light blocking plate can block the light path to simulate the triggering of the light path when a car passes by, so as to realize offline debugging of the light blocking triggering function. The light blocking triggering function of the motor vehicle exhaust telemetry device can be debugged offline without the need for on-site debugging of the car. Each time the light blocking plate blocks the propagation of light, it represents that a car has passed by, thereby improving the use stability of the triggered exhaust telemetry device.

[0011] The structural design of the light blocking plate of the present invention is that when the light source in the light transmission tube 1 is damaged, no matter whether the light blocking plate is blocked between the light transmission tube 1 and the light transmission tube 2, the device will automatically determine that no light signal is received, i.e., it is determined that a car has been passing through during the simulation process. At this time, the light receiver on the side of the light blocking plate close to the light source will start the light transmitter on the other side to emit light because it has not received the light source, and the device will continue to work normally. However, at this time, the light blocking plate will provide a light source each time it passes between the light transmission tube 1 and the light transmission tube 2, i.e., when the light blocking plate is between the light transmission tube 1 and the light transmission tube 2, the device automatically determines that no car has passed through, and when the light blocking plate leaves between the light transmission tube 1 and the light transmission tube 2, the device automatically determines that a car has passed through. This is an effective work supplement for when the light source in the light transmission tube is damaged and the staff cannot detect it, and can still simulate the light blocking to trigger the exhaust gas detection equipment, thereby improving the use efficiency of the equipment.

[0022] A rotating electromagnet 5 is arranged below the light transmission tube 2, and a rotating electromagnet mounting seat 6 is fixedly arranged on one side of the rotating electromagnet 5. The output shaft of the rotating electromagnet 5 is rotatably connected to the rotating electromagnet mounting seat 6. The output shaft of the rotating electromagnet 5 passes through the rotating electromagnet mounting seat 6 and can realize rotation in the rotating electromagnet mounting seat 6. The light blocking plate 4 is fixedly connected to the output shaft of the rotating electromagnet 5. Through the operation of the rotating electromagnet 5, the output shaft can drive the light blocking plate 4 to rotate, thereby simulating that the light blocking plate 4 rotates once to block the light, which represents that a car passes by, and then the exhaust gas detection equipment can be controlled to start. The output shaft of the rotating electromagnet 5 is also fixedly connected with The counterweight block 7 is fixed on the shaft at one end away from the light baffle 4, which can better drive the light baffle 4 to rotate.
