However, the laser telescope on the market at present is mainly implemented by a high-speed adc+a high-speed FPGA (Field Programmable GATE ARRAY ), and the ranging method mainly has the following disadvantages:

D. The precision is poor: the laser ranging has high requirement on the measuring speed, and the measuring precision is not high due to the limited speed of the FPGA.
In view of this, the present application provides a ranging scheme for a laser ranging telescope based on MS1003, which can effectively solve the above-mentioned problems.
Referring to fig. 1, the embodiment of the application discloses a ranging circuit of a laser ranging telescope based on an MS1003, which mainly comprises:
A microcontroller 101, an MS1003 chip 102, a high-voltage laser transmitting circuit 103 and a laser receiving and amplifying circuit 104;
The microcontroller 101 is used for generating a start pulse and sending the start pulse to the MS1003 chip 102 and the high-voltage laser emission circuit 103;
the high-voltage laser emission circuit 103 is used for emitting laser to a target according to the starting pulse;
The laser receiving and amplifying circuit 104 is used for detecting the laser reflected from the target, generating a STOP pulse and transmitting the STOP pulse to the STOP1 channel of the MS1003 chip 102;

The microcontroller 101 is used for reading time data in the MS1003 chip 102, and calculating and generating distance data to a target.
First, it should be emphasized that the ranging circuit of the laser ranging telescope disclosed in the embodiments of the present application is specifically implemented based on the chip MS 1003. The MS1003 is a time measurement chip with high precision, low power consumption, low cost, multiple pulses and simple operation, and has the following advantages:
A. High precision: the MS1003 adopts an advanced process, the highest measurement precision can reach 23 picoseconds, and the measurement precision of 3 millimeters can be realized;
B. Low power consumption: the MS1003 has an operation mode and a low power consumption mode, wherein the power consumption current of the operation mode is 4 milliamperes, and the power consumption current of the low power consumption mode is 1 microampere;
C. Multipulse: MS1003 has two measurement channels, each with up to 10 measurable pulses, up to 20 targets;
D. the operation is simple: the user only needs to access the sending and receiving signals into the MS1003 chip 102, reads data through an SPI interface and performs distance conversion to obtain a ranging result, and the implementation process is convenient and simple;
E. low cost: the MS1003 has high integration level, and the package body adopts QFN20, so that the area and the cost are greatly reduced;
F. The measuring distance is wide: the MS1003 measurement time is 2.5 ns-20 us, and the measurement distance can realize seamless measurement of 0-3000 m.
It should be further noted that, the START port of the MS1003 chip 102 is specifically connected to the microcontroller 101, and is configured to receive a START pulse sent by the microcontroller 101. It will be readily appreciated that the signal received at the START port is used to trigger the timer on the timer function within the MS1003 chip 102 and the signal received at the STOP channel interface is used to trigger the timer off the timer within the MS1003 chip 102.
In the present application, the START pulse sent by the microcontroller 101 is sent to the high-voltage laser emission circuit 103, so that the high-voltage laser emission circuit 103 emits laser to the target, and is also sent to the START port of the MS1003 chip 102, so that the MS1003 chip 102 STARTs timing.
After receiving the laser beam reflected from the target, the laser beam receiving and amplifying circuit 104 generates a STOP pulse, and sends the STOP pulse to the STOP1 channel of the MS1003 chip 102, thereby stopping the timer. The time difference between the rising edge time of the start pulse and the rising edge time of the stop pulse detected by the MS1003 chip 102 is the flight time of the laser, so that the time difference can be used for performing ranging calculation. Thus, when the MS1003 chip 102 completes detection, the detected time data will be read by the microcontroller 101 as a data basis for calculating the distance to the target.
Therefore, the ranging circuit of the laser ranging telescope disclosed by the embodiment of the application realizes time measurement based on the MS1003 chip 102, and can accurately, efficiently and simply realize laser ranging by utilizing the signal links between the microcontroller 101 and the MS1003 chip 102 and the signal links between the laser receiving and amplifying circuit 104 and the MS1003 chip 102 as well as the signal links between the microcontroller 101 and the MS1003 chip 102, thereby greatly reducing equipment cost and power consumption and improving the economic benefit of products.
Referring to fig. 2, fig. 2 is a schematic circuit diagram of a ranging circuit of a laser ranging telescope based on an MS1003 according to an embodiment of the present application.
As a specific embodiment, the ranging circuit of the laser ranging telescope based on MS1003 disclosed in the embodiment of the present application is based on the above description, and the microcontroller 101 is respectively connected to the chip select terminal SSN, the clock signal terminal SCK, the data input terminal SI, the data output terminal SO, and the reset control terminal RSTN of the MS1003 chip 102.
As a specific embodiment, the ranging circuit of the MS 1003-based laser ranging telescope disclosed in the embodiment of the present application is based on the above description, where the microcontroller 101 is connected to the interrupt output terminal INTN of the MS1003 chip 102, and is configured to read the time data in the MS1003 chip 102 after receiving the interrupt signal from the interrupt output terminal INTN.
As a specific embodiment, the ranging circuit of the MS 1003-based laser ranging telescope disclosed in the embodiment of the present application is based on the above description, and the laser receiving and amplifying circuit 104 is respectively connected with the STOP1 channel and the STOP2 channel of the MS1003 chip 102, and is used for respectively sending the generated STOP pulse to the STOP1 channel and the STOP2 channel;
The STOP2 channel of the MS1003 chip 102 is configured in a falling edge timing detection mode, and a time difference between a falling edge timing and a rising edge timing of the STOP pulse is used to identify a different STOP pulse.
Note that the START port and STOP1 interface of the MS1003 chip 102 are configured in the rising edge timing detection mode, and the STOP2 interface is configured in the falling edge timing detection mode. The STOP1 interface and the STOP2 interface detect the STOP pulse transmitted from the laser receiving and amplifying circuit 104, respectively, and thus the time difference between the detection of the two STOP channels is the pulse width of the STOP pulse.
Since the targets of different material have different reflectivities for the same laser light, the pulse width of the stop pulse generated by the laser receiving amplification circuit 104 is different. Thus, in the present application, the pulse width of the STOP pulse can be acquired based on the two STOP channels of the MS1003 chip 102, so as to further identify different targets.
The laser receiving and amplifying circuit 104 mainly comprises a receiving diode and an amplifying and comparing circuit; the high-voltage laser emission circuit 103 mainly includes a high-voltage circuit and an emission diode.
As a specific embodiment, the ranging circuit of the MS 1003-based laser ranging telescope disclosed in the embodiment of the present application is based on the above description, and the microcontroller 101 is connected to the STOP1 channel enable terminal en_ STOPI and the STOP2 channel enable terminal en_stop2 of the MS1003 chip 102, respectively.
As a specific embodiment, the ranging circuit of the MS 1003-based laser ranging telescope disclosed in the embodiment of the present application is based on the above description, and the pulses continuously captured by the STOP1 channel and the STOP2 channel at a time are multiple, so as to achieve multi-target ranging.
As before, each STOP channel of MS1003 may last for a maximum of 10 pulses per time. Therefore, by utilizing the multi-pulse capturing advantage and the dual-channel detection advantage of the MS1003, the pulse width of the stop pulse corresponding to different targets can be identified, and multi-target ranging can be realized.
In practical applications, there may be some obstacles between the telescope and the target, such as birds, raindrops, etc., that affect the accuracy of ranging. The multi-target ranging function of the ranging circuit provides a realization basis for identifying the obstacle according to the pulse width characteristics of different types of targets (the pulse width of the obstacle is generally smaller), or provides a realization basis for identifying the obstacle according to the pulse reflection time characteristics of different types of targets (the pulse reflection of the obstacle is earlier than that of the target), so that the ranging circuit can further effectively provide ranging accuracy.
Referring to fig. 3, an embodiment of the application discloses a ranging method of a laser ranging telescope based on an MS1003, which is applied to a microcontroller 101 in a ranging circuit as described above, and the method mainly includes:
s201: a reset instruction is sent to the MS1003 chip 102.
Specifically, the reset operation includes a hardware reset and a software reset. The RSTN pin of microcontroller 101 to MS1003 sends a negative pulse of greater than 10 μs to perform a hardware reset, and then writes a 0x50 command to MS1003 via the SPI port to perform a software reset.
S202: and sending a configuration instruction and an initialization instruction to the MS1003 chip 102 to enable the MS1003 chip 102 to complete configuration and initialization.
Specifically, the microcontroller 101 configures the MS1003 by writing configuration parameters to configuration registers of the MS 1003. The configuration register of the MS1003 is composed of an 8-bit address and a 32-bit configuration parameter, the 8-bit address is 0x80, and the 32-bit configuration parameter is specifically set as follows: 0xBB084460, representing: both STOP1 and STOP2 are expected to receive 10 pulses; generating a calibration factor (CAL value) based on the non-calibration mode; START and STOP1 are both rising edge time capture mode, STOP2 is falling edge time capture mode; the End bits stop pulse monitor state is turned on and the Timeout interrupt source is turned on.
The microcontroller 101 may then initialize the MS1003 by sending 0x 70.
S203: a start pulse is generated and transmitted so that the high-voltage laser emission circuit 103 emits laser light to the target, and the MS1003 chip 102 starts timing with the rising edge of the start pulse as the laser emission time.
Specifically, the microcontroller 101 sends a START pulse to the high voltage laser transmitter circuit 103 and the START port of the MS1003, and the internal timer of the MS1003 STARTs to count.
S204: after the laser receiving amplification circuit 104 detects the laser light reflected from the target and generates a STOP pulse, the MS1003 chip 102 detects the rising edge of the STOP pulse as the laser light receiving timing based on the STOP1 channel, and the timing data in the MS1003 chip 102 is read.
Specifically, the laser light is reflected back after being emitted to the target, the laser light receiving and amplifying circuit 104 receives the processed output STOP pulses to STOP1 and STOP2, the MS1003 STOPs the timer and stores the measured time data in the result register. If there are multiple targets, the laser will reflect and receive multiple times, and time multiple times. MS1003 may receive up to 10 target-returned STOP pulses per STOP channel.
S205: distance data to the target is calculated and generated according to the time data.
As a specific example, after the MS1003 completes the pulse detection, the microcontroller 101 may be notified by an interrupt signal, so that the microcontroller 101 may perform data reading. That is, the INTN port of the MS1003 may generate a low level to inform the microcontroller 101 that the measurement is completed, and the microcontroller 101 may read the data stored in the result register to complete the time measurement of one laser ranging.
After the measurement is completed, the registers may be reconfigured to put the MS1003 from an operational mode into a low power mode.
Therefore, the ranging method of the MS 1003-based laser ranging telescope provided by the application realizes time measurement based on the MS1003 chip 102, and utilizes the signal links between the microcontroller 101 and the MS1003 chip 102 and between the laser receiving and amplifying circuit 104 and the MS1003 chip 102 as well as the signal links between the microcontroller 101 and the high-voltage laser transmitting circuit 103, so that the laser ranging can be realized accurately, efficiently and simply, the equipment cost and the power consumption are greatly reduced, and the economic benefit of the product is improved.
As a specific embodiment, in the ranging method based on the laser ranging telescope of the MS1003 according to the embodiment of the present application, after sending a configuration instruction and an initialization instruction to the MS1003 chip 102 to complete configuration and initialization of the MS1003 chip 102, the communication test may be further performed on the MS 1003.
Specifically, a communication register is provided in the MS1003 for verifying whether the microcontroller 101 and the MS1003 communicate normally. The communication register of the MS1003 is composed of an 8-bit address and 8-bit data. When the communication test is performed, the microcontroller 101 can write in the 8bit address 0xBC first, then read the 8bit data, and if the data is 0x60, the communication is successful; otherwise, the communication failure is indicated.
As a specific embodiment, the ranging method based on the laser ranging telescope for the MS1003 provided by the embodiment of the present application may further perform a CAL value test on the MS1003 after performing a communication test on the MS1003 on the basis of the above description.
Specifically, the CAL value is the time of measuring a high-speed reference clock (Tref) by using the timer of the MS1003, and after the measurement is completed, the measured value is saved to the corresponding result register. The CAL value of the test and verification MS1003 can be used to calibrate the time data measured later to obtain absolute time, so as to improve the measurement accuracy. Specifically, microcontroller 101 may initiate a CAL value test by sending a command of 0x04, and then read the CAL value of Tref measured by sending a command of 0 xBB.
For example, STOP-1 has a first pulse value of STOP-1_Result1 and STOP-2 has a first pulse value of STOP-2_Result; when the CAL value test is performed on the MS1003, if 1 time Tcal of Tref (i.e., CAL value of Tref) is measured by using the timer, the calibrated time data is:
Tstop1_1＝Tref/Tcal*STOP1_Result1；
Tstop2_1＝Tref/Tcal*STOP2_Result1；
the calculation of the latter pulse is similar. Further, the pulse width can be obtained by using TSTOp2_1-TSTOp1_1, and laser compensation and target judgment can be performed through the pulse width.
