As shown in FIG1 Figure 1b As shown, when the foldable push rod 3 is not needed for certain operations, the push rod can be placed on the push rod support 211 on the upper surface of the foldable support rod 2.

[0036] The equipment in this embodiment realizes the following functions: line mileage measurement, equipment limit measurement (geod reference), straight-line distance measurement (handheld laser) and data upload table generation.

[0037] Technical parameters of the equipment in this embodiment: 1. Mileage accuracy: ±0.5m / km; 2. Limit distance measurement range: horizontal distance 1~10m, vertical distance -1~3m; accuracy: horizontal distance -5~0mm, vertical distance ±5mm; 3. Straight distance range: 5~1500m; accuracy: ±0.5m; 4. Comes with lithium battery, total weight ≤10kg, working temperature -30℃~50℃; 5. Can be separated into main unit and support arm, and the support arm can be folded; 6. The supporting APP supports file template import and export, and generates the required records directly according to the template; 7. Short press the manual button to record the distance measurement data, and long press to clear it; 8. Measurement pause and resume function, convenient for temporary vehicle giving way.

[0038] Working principle of the equipment in this embodiment: After the rangefinder body 1 and the foldable support rod 2 are installed, a double-track three-point support is formed, which ensures the stability of the equipment and can be placed stably without relying on personnel. Dual mileage detection, always monitor the reading difference of the two sets of high-precision encoders, and calculate the distance moved by the roller. When the difference is too large, it means slipping, an alarm is issued and recorded. Select a set of data with a fast rotation speed as the correct displacement. According to actual tests, when pushing in a certain direction, the front roller will first slip, jam or derail, so the encoder at the rear should be used as the data source. The measurement of the limit is composed of a laser ranging module and an encoder module. The ranging module obtains the distance, the encoder obtains the rotation angle, and the horizontal and vertical distances of the measured point relative to the track surface can be calculated by trigonometric functions. Real-time measurement after powering on, and Bluetooth data is sent to the APP at any time to display the current mileage. 1km laser ranging is used to measure the straight-line distance along the rail direction, and 10m laser ranging is used to measure the limit distance in the direction perpendicular to the rail. The control button 34 on the foldable push rod 3 is short pressed to send the marked data, and long pressed to clear the mileage to 0. The APP calculates the mileage and distance to obtain the distance required by the customer and records it in a table. The handheld distance meter 4 is used for auxiliary measurement, and its data is manually checked and recorded by the operator.

[0039] The specifications of the laser distance measuring sensor 134 of the device of this embodiment are shown in Table 1 below:

[0040]

[0041] Table 1

[0042] The specifications of the inclination sensor 135 of the device of this embodiment are shown in Table 2 below:

[0043]

[0044] Table 2

[0045] The hardware solution of the main control board 15 of the device in this embodiment is as follows:

[0046] Function and interface

[0047] LCD SPI (1 channel), temperature and humidity IIC (1 channel), encoder 232 (2 channels for mileage), encoder 485 (1 channel for inclination), laser serial port (1 channel TTL), Bluetooth serial port (1 channel TTL);

[0048] 5 / 12V power supply (2 channels for mileage, 1 channel for inclination), 5V power supply (1 channel for laser), 3.3V power supply (1 channel for LCD, 1 channel for Bluetooth, 1 channel for temperature and humidity);

[0049] Since the microcontroller has only 4 serial ports, the two mileages need to share one serial port, use different slave addresses to distinguish them, and cannot use the automatic sending mode, only the response mode.

[0050] Microcontroller

[0051] Considering the trend of using domestic chips in the future, STC32G2K128 is used, which has 64 pins, internal high-precision IRC (6M, 10M, 27M, 44M) and PLL (96M, 144M), can be directly connected to the U port, and the internal reference source is 1.19V (±1%).

[0052] power supply

[0053] Use 20000mAH 3.7V lithium battery and power supply circuit. The first level 3.7V is used for charging and discharging board, and IP2312U chip is used for charging and discharging management. The second level uses LM27313 to output 5V as the power supply for encoders, laser ranging modules, 232 communication, 485 communication, and the third level uses multi-channel MCP 1700 to output 3.3V to the microcontroller, LCD display, buttons, Bluetooth, and buzzer as the power supply part.

[0054] AD Sampling

[0055] 3.7V is sent to the AD port of the microcontroller after resistor voltage division. The microcontroller is connected to AGND, AGND is connected to GND at a single point, and the reference power supply is directly 3.3V digital power supply.

[0056] LCD display

[0057] The LCD is only used temporarily during equipment debugging and is removed when it is officially used to save energy and meet long-distance measurement. All displays are uploaded to the client display record via Bluetooth.

[0058] The embedded code solution of the device in this embodiment:

[0059] 1. The timer is used as the system time base and interrupts once every 2ms.

[0060] 2. The timer is used as the common baud rate generator of the serial port, which is unified as 115200.

[0061] 3.SPI uses the original code.

[0062] 4. The original Bluetooth code of the serial port and the original tilt sensor code of the serial port 1234 need to be changed to laser ranging.

[0063] 5. Serial port 12 uses DMA. Serial port 1 uses a 485 encoder to measure inclination and an external encoder to measure mileage; serial port 2 uses a 232 encoder to measure mileage.

[0064] 3.232 encoder calculation method: use 1 query, either single-turn value or multi-turn value. Single-turn value can be memorized when power is off, and multi-turn value is cleared to 0 when power is off. It is inconvenient to query the number of turns more often. The query frequency of the prototype is 12ms when idle and 40ms when busy, and the sending time is less than 1ms. Each calculation, the turn value difference * mileage coefficient = mileage difference, and then get the current 232 mileage.

[0065] 7.485 encoder calculation method: 1 query contains single-turn value and number of turns. First calculate the number of turns difference, then calculate the turn value difference. After obtaining the total turn value difference, turn value difference * mileage coefficient = mileage difference, and then obtain the current 485 mileage.

[0066] 8. Use of mileage: Both sets of mileage are set to 4096 bytes / circle. To prevent slipping, the one with the largest change is taken as the final data.

[0067] 9. Bluetooth: Send mileage as a heartbeat frame every 0.6 seconds. Press the button to send mileage directly.

[0068] 10. Push rod button: Short press the push rod button to send the mileage directly via Bluetooth, and long press it to reset the mileage.

[0069] 11.Body button: short press to switch working mode, long press to light up, pause / resume mileage changes.

[0070] The above description is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description are still within the scope of the patent of the present invention.
