The speed measuring ruler 1 is arranged on the detected object to be integrated, so that the moving speed of the object can be measured in real time. The principle of speed measurement is as follows: when the speed measuring ruler 1 moves forward along with an object, a laser irradiation point moves from the black substrate 8 to the light reflecting patch 9, so that light is reflected to reach the photoelectric sensor 4, discontinuous reflection laser of the light reflecting patch 9 on the speed measuring ruler 1 is utilized to convert the motion information of the detected object into an electric signal, and meanwhile, the light reflecting patch 9 is made of a retro-reflection material, so that the laser basically returns along the original route. The photoelectric sensor 4 transmits the electric signal to the signal processing circuit 5, the electric signal is amplified, filtered and shaped by the signal processing circuit 5 to form a good rectangular wave signal, the singlechip 7 receives the rectangular wave signal fed back by the signal processing circuit 5 and carries out speed calculation, and finally calculated speed data is displayed on a corresponding display.
The utility model adopts the speed measurement principle of a transmission-type speed measurement ruler: the basic process of speed measurement is shown in fig. 3, and the principle of speed measurement of the transmission-type speed measuring ruler 1 is as follows: when the speed measuring ruler 1 moves along with a measured object, laser light received by the photoelectric sensor 4 is blocked when the laser light irradiates the black bottom plate 10, when the measured object moves to the position where the laser light irradiates from the black bottom plate 10, the photoelectric sensor 4 senses light again, the movement information of the measured object is converted into an electric signal by using a signal which is similar to a rectangular wave generated by discontinuous shielding of the speed measuring ruler 1 on the laser light, the electric signal is transmitted to the signal processing circuit 5 by the photoelectric sensor 4, the electric signal is amplified, filtered and shaped by the signal processing circuit 5 to form a good rectangular wave signal, the singlechip 7 receives the rectangular wave signal fed back by the signal processing circuit 5 and carries out speed calculation, and finally calculated speed data is displayed on a corresponding display.
The principle of calculation of the speed data is as follows: the rectangular wave fed back by the signal processing circuit 5 is input into the single chip microcomputer 7 as a signal to be processed, a speed value is calculated by using the obtained time t and the reflecting ruler parameter s according to the formula v ═ s/t and is displayed on a corresponding display, and a speed measurement signal processing flow chart is shown in fig. 7. Firstly, initializing the system to ensure that each interface is at a normal potential and emptying the memory. And then, inputting the signal for decision making, triggering a timer at the rising edge of the rectangular wave to count the falling edge, stopping the timer and outputting time t. Then, the subprogram is used for calculating to obtain the speed and displaying the speed on the nixie tube to finish the speed measuring process.
The basic process of positioning is shown in fig. 6: the scheme in example 3 is taken as an example for illustration: the scheme comprises a laser emitter 3, a photoelectric sensor 4, a signal processing circuit 5, a direction-sensing circuit 12 and a singlechip 7. The basic flow for realizing positioning is as follows: constant current power supply 6 is as laser emitter 3's power supply unit, make laser emitter 3 can launch stable continuous laser irradiation on speed measuring chi 1, use 2 parallel arrangement's laser emitter 3 and 2 parallel arrangement's photoelectric sensor 4, make the distance between 2 laser emitter 3 and 2 photoelectric sensor 4 be 1/2 width of reflection of light paster 9, each laser emitter 3 corresponds a photoelectric sensor 4 and receives laser signal, guarantee that the signal that 2 photoelectric sensor 4 produced differs 1/4 cycle in the phase place, photoelectric sensor 4 converts the laser signal who receives into the signal of telecommunication, send for signal processing circuit 5 and convey after signal processing circuit 5 handles and distinguish circuit 12, distinguish the direction of motion through distinguishing circuit 12. And finally, the coordinate information is processed and output by the singlechip 7 to determine the specific position of the vehicle.
The positioning rationale is implemented as follows: the positioning method mainly comprises the step of detecting the number of the light reflecting sheets or the square holes on the speed measuring ruler by using the photoelectric sensor so as to realize positioning. The description will be made by taking the reflective type as an example. The movement information of the detected object is converted into an electric signal by utilizing discontinuous reflection laser of the reflective patch 9 on the reflective speed measuring ruler 1. When the speed measuring ruler 1 moves forward along with an object, light rays can be reflected to reach the photoelectric sensor 4 when the laser irradiation point moves on the speed measuring ruler 1 and reaches the reflector, until the reflector completely passes through the laser irradiation point, the laser irradiation point moves from the reflector 9 to the black substrate 8, and the photoelectric sensor 4 does not sense light any more and then completes the detection of one reflector 9.
The basic flow of positioning signal processing is shown in fig. 8: whether a rising edge signal exists or not needs to be detected as an initial position of positioning, then the number of the rising edges in the obtained signal is recorded, each rising edge represents one light reflecting patch 9 or strip-shaped hole 11, the moving distance of an object is obtained by detecting how many light reflecting patches 9 or strip-shaped holes 11 the photoelectric sensor 4 moves through, and when the number of the rising edges reaches a limited number, the detected object passes through. Since it is impossible to move the vehicle in one direction all the time, it is necessary to distinguish the moving direction of the vehicle. And distinguishing the moving direction of the transport vehicle by using a direction distinguishing circuit. The principle of direction sensing is as follows: if the right photosensor 4 senses light earlier than the left photosensor 4, the signal obtained from the right side leads the signal from the left side by 1/4 phases, and the discrimination of the moving object is performed by the discrimination circuit in the left direction and in the right direction, so that the discrimination of the moving direction of the object can be realized. When the transport vehicle moves forward, the negative pulse number output by the direction-identifying circuit 12 represents that no action is needed because the transport vehicle does not need to be maintained, and when the transport vehicle returns, the positive pulse number output by the direction-identifying circuit 12 is positioned in real time.
