Description

Technical Field

[0001] The utility model belongs to the field of electrical technology and relates to a servo control solution circuit board detection device for an unmanned aerial vehicle optoelectronic monitoring / aiming device. The utility model is applied to the assembly and adjustment process of the mass production of the unmanned aerial vehicle optoelectronic monitoring / aiming device to detect the functions of the servo control module and the shaft angle solution module of the servo control solution circuit board of the unmanned aerial vehicle optoelectronic monitoring / aiming device. Background Art

[0002] The servo control solver circuit board is the core component of the optoelectronic monitoring / aiming device of the unmanned aerial vehicle. In the prior art, there is no special equipment to detect the servo control solver circuit board of the optoelectronic device, which results in two problems in the debugging process of the whole machine: first, after the servo control solver circuit board of the optoelectronic device is welded, the circuit board is directly placed on the whole machine system for inspection, and the whole machine system is powered by a DC regulated power supply. The optoelectronic monitoring / aiming device is operated to detect whether the welding and function of the servo control solver circuit board are normal. The operating space on the whole machine is limited and there are many sensitive components on the circuit board. It is inconvenient to plug and unplug the optoelectronic monitoring / aiming device, which is easily damaged by electrostatic breakdown and causes short circuit. The short circuit of the circuit board may damage other components. This debugging method has the risk of damaging the whole machine system and the circuit board. Secondly, after the circuit board is welded, it is necessary to wait for the assembly of the mechanical parts of the whole machine and the routing of the cables. After the preliminary inspection is completed, the circuit board is directly placed on the whole machine system for inspection, and the servo control solution of the circuit board function is inspected by operating the optoelectronic turret. Then the circuit board is sprayed with three-proof paint, and the circuit board is screened for environmental tests, etc., and then placed on the whole machine for whole machine debugging, environmental testing, and delivery. This single-channel serial debugging method involves a long waiting time and waste, which affects the debugging efficiency of the optoelectronic device of the UAV system. Utility Model Content

[0034] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.

[0035] like Figure 1 As shown, the servo control solver circuit board detection device of the unmanned aerial vehicle optoelectronic monitoring / aiming device in this embodiment is used to detect the servo control shaft angle solver circuit board (hereinafter referred to as: servo control solver circuit board), including a power conversion module 10, a liquid crystal display module 11, a processor module 12, a level conversion module 13, an interface module 14, a pressure sensor module 15, and a resolver solver module 16.

[0036] The input end of the power conversion module 10 is connected to a 110V-240V AC power supply through a power cable, and the output end is respectively connected to a liquid crystal display module 11, a processor module 12, a level conversion module 13, an interface module 14, and a pressure sensor module 15; the power conversion module 10 converts 110V-240V AC power into DC power required by each module connected to the output end.

[0037] The resolver resolver module 16 is connected to the servo control resolver circuit board through the interface module 14. The servo control resolver circuit board provides an analog reference signal for the resolver resolver module 16. The resolver resolver module 16 provides an axis angle analog signal input for the servo control resolver circuit board. The servo control resolver circuit board converts the analog signal into digital and outputs a digital level signal.

[0038] The level conversion module 13 is connected to the servo control solver circuit board through the interface module 14, converts the digital level signal output by the servo control solver circuit board into a digital level signal available to the processor module 12, and outputs it to the processor module 12;

[0039] The processor module 12 is connected to the liquid crystal display module 11. The processor module 12 processes the digital level signal input by the level conversion module 13 with a set algorithm and outputs it to the liquid crystal display module 11 for display. By observing the continuity of the shaft angle data displayed by the liquid crystal display module 11, it is detected whether the solving function of the servo control solving circuit board is normal.

[0040] The pressure sensor module 15 is connected to the servo control solver circuit board through the interface module 14. The pressure sensor module 15 provides a voltage analog signal input for the servo control solver circuit board. The servo control solver circuit board amplifies and corrects the voltage analog signal and outputs it to the data processed output processor module 12; the processor module 12 is connected to the servo control solver circuit board, converts the analog voltage data sent by the servo control solver circuit board into digital form and outputs it to the liquid crystal display module 11; by observing the positive and negative and size of the voltage value displayed on the liquid crystal display module 11, it is possible to detect whether the direction of the control function and the control effect of the servo control solver circuit board are normal.

[0041] like Figure 2 As shown, in the detection device of this embodiment, the power conversion module 10 includes an AC-DC voltage converter of model ACE-A627A-RS-R11; the liquid crystal display module 11 includes a liquid crystal screen of model LCD12684 and its peripheral circuits; the processor module 12 includes a single-chip microcomputer of model MSP430149 and its peripheral circuits, and the single-chip microcomputer is burned with software code written in C language; the level conversion module 13 includes a level conversion transceiver of model SN74ALVC164245; and the interface module 14 uses a 152-pin socket.

[0042] The power conversion module 10 uses AC 110-240V as input, and converts the input AC power into ±15V, ±12V, ±5V, ±3.3V DC output, which respectively powers the liquid crystal display module (LCD12864), the processor module (MSP430 microcontroller), the level conversion module (SN74ALVC16245), and the pressure sensor module.

[0043] The servo control solver circuit board is connected to the resolver solver module 16, and the resolver solver module 16 outputs sine wave and cosine wave analog signals with a peak-to-peak value of 15V, a frequency of 400HZ, and a phase difference of 90°, which are simultaneously sent to the 6-channel shaft angle solver circuit board of the servo control solver circuit board.

[0044] The shaft angle resolution circuit of the servo control resolution circuit board converts the analog signal A / D input by the resolver resolver module 16 into a 16-bit 5V TTL level digital signal.

[0045] Since the I / O port of the MSP430 microcontroller used in this device can only withstand a maximum voltage of 3.3V, the 16-bit 5V TTL-level digital shaft angle data signal generated by the 6-channel shaft angle resolution circuit of the servo control resolution circuit board is converted into 16-channel 3.3VTTL-level digital shaft angle data signals through the level conversion module and output to the P1 and P2 ports of the microcontroller for use by the microcontroller;

[0046] The P3.0-P3.6 I / O ports of the single-chip microcomputer control the ENABLE and INHIRIT high and low levels of the R2D chip in the 6-way shaft angle calculation circuit to output the shaft angle calculation data in turn. The flow chart is as follows: Figure 3 As shown; the liquid crystal display module 11 is connected to the output of the processor module 12, and the 6-channel axis angle data is displayed on the liquid crystal display module 11.

[0047] The pressure sensor module 15 is connected to the servo control solver circuit board through the interface module 14 to provide an analog voltage input that continuously changes from 0 to +3.3 for the correction network circuit part of the servo control solver circuit board.

[0048] The processor module 12 is connected to the output of the interface module 14, and the analog voltage processed by the servo control circuit board correction network part is sampled and processed by the algorithm, and the sampled voltage value is output; the liquid crystal display module 11 is connected to the output of the processor module 12, and the sampled voltage value is displayed on the display module.

[0049] like Figures 4 to 6 As shown, the resolver resolver module 16 includes a dual-channel resolver transmitter model J60XFD001, a bearing, and a rotating handle; the pressure sensor module 15 is a dual-axis button remote sensing sensor.

[0050] The detection device of this embodiment also includes a device housing, a power indicator light, a switch, a short-circuit protection circuit, and key signal detection points.

[0051] In this embodiment, the INHIBIT of the 6-channel axis angle solving chips is uniformly set from logic high to low by controlling the P3.6I / O port of the single-chip microcomputer, and the data of the 6-channel axis angle solving chips are placed in the corresponding latches. The ENABLE of the 6-channel axis angle solving chips is sequentially set from logic high to logic low by controlling the P3.0-P3.5I / O ports of the single-chip microcomputer, so that the solved data is output to the pins in sequence, and finally the INHIBIT of the 6-channel axis angle solving chips is uniformly set from logic high to low to complete one data transmission.

[0052] It can be seen from the above technical solution that the utility model has the following significant features:

[0053] (1) This device can replace the whole system of the UAV optoelectronic monitoring / aiming device to complete the detection of the servo control function and axis resolution of the servo control resolution circuit board;

[0054] (2) The device uses a pressure sensor module to provide a continuously changing voltage input for the servo control solver circuit board. The processor converts the feedback output analog quantity of the servo control solver circuit board into a digital quantity and displays it on the display module, thereby realizing the servo control function detection of the servo control solver circuit board;

[0055] (3) The device uses a resolver module to provide input for the servo control solver circuit board, processes the continuously changing shaft angle value through the processor algorithm and displays it on the display, thereby realizing the shaft angle solving function detection of the servo control solver circuit board;

[0056] (4) This device uses a 110V~240V AC power supply instead of a DC regulated power supply.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
