[0002] Reconnaissance capabilities are an essential component of a unit's combat effectiveness. Pre-war deployment requires accurate intelligence, in-fight coordination requires timely and accurate battlefield situational awareness, and precision strikes, in particular, require precise target information. Currently, the military is significantly lacking in this area. The reasons are multifaceted, but a lack of high-quality target reconnaissance and positioning equipment is a key factor. Generally speaking, the military's existing observation equipment is relatively simple. Most units are equipped only with laser rangefinders, which are unable to accurately locate targets. Only some special operations and reconnaissance units are equipped with digital target reconnaissance and positioning devices. A comprehensive upgrade would require the complete elimination of existing laser rangefinders, resulting in significant waste. Summary of the Invention

The power module of the laser rangefinder supplies power to the target reconnaissance and positioning device. The other power supply interface serves as a backup port. When the power of the laser rangefinder is low, an external power supply is connected to the external power supply. The external power supply supplies power to the target reconnaissance and positioning device and the laser rangefinder, and charges the power storage unit of the laser rangefinder.

[0011] The positioning and orientation device is connected to two antennas. After the antenna bracket is unfolded, the angle between the line connecting the two antennas and the emission axis of the laser rangefinder is equal to the preset angle and remains unchanged during use.

[0012] The shell is connected to the laser rangefinder through a plug-in structure.

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] like Figure 1 、 2 As shown in 3, the target reconnaissance and positioning device matched with the rangefinder includes a shell 1 connected to the laser rangefinder 12, and a positioning and orientation device, an angle sensor, a display and control device and a processor are arranged in the shell 1. The positioning and orientation device, the angle sensor and the display and control device are all connected to the processor.

[0024] If data is directly transmitted between the target reconnaissance and positioning device and the laser rangefinder 12, the laser rangefinder 12 directly transmits the target distance data to the target reconnaissance and positioning device and triggers the target reconnaissance and positioning device to start. A communication interface 6 connected to the processor is provided on the housing 1, generally provided on the side for easy connection. The communication interface 6 is connected to the data output port of the laser rangefinder 12, and direct transmission of data between the two is achieved through the communication interface 6; if data is not directly transmitted, indirect transmission can be performed. The communication interface 6 does not need to be provided on the housing, and the data can be directly input through the button 5 of the display and control device. A start button needs to be provided on the target reconnaissance and positioning device, and the start button is connected to the processor. The start button of the target reconnaissance and positioning device and the start button of the laser rangefinder are triggered together, thereby achieving the start of the two devices together.

[0025] The housing 1 is provided with a power interface 7 connected to the processor, which is generally arranged on the side for easy connection. The power interface 7 is connected to the power module of the laser rangefinder 12 or an external power supply. Two power interfaces 7 can be provided. One power interface 7 shares a port with the communication interface 6 and is connected to the power module of the laser rangefinder 12. The power module of the laser rangefinder 12 supplies power to the target reconnaissance and positioning device; one power interface 7 serves as a backup port. When the laser rangefinder 12 is low on power, the external power supply is connected. The external power supply supplies power to the target reconnaissance and positioning device and the laser rangefinder 12, and charges the power storage unit of the laser rangefinder 12.

[0026] The positioning and orientation device is a combination of a dual-antenna satellite positioning and orientation device, an inertial navigation device and an electronic compass. The positioning and orientation device comprehensively utilizes dual-antenna satellite positioning and orientation technology, inertial navigation technology and an electronic compass to achieve complementary advantages. The positioning and orientation device is not limited to the combination of the above-mentioned devices, but only needs to achieve the purpose of orientation and orientation.

[0027] The positioning and orientation device is connected to the antenna 4 . An antenna bracket 3 is provided on the housing 1 , and the antenna 4 of the positioning and orientation device is installed on the antenna bracket 3 .

[0028] The antenna bracket 3 is an expandable and retractable mechanism. The antenna bracket 3 is rotatably connected to the housing 1. The antenna bracket 3 is positioned with the housing 1 by a positioning member. The angle of the antenna bracket 3 is consistent each time it is deployed. Specifically, one end of the antenna bracket 3 is connected to the housing 1 by a rotating shaft 10. The other end of the antenna bracket 3 has an antenna mounting hole. The antenna 4 is installed in the antenna mounting hole. After the antenna bracket 3 is deployed, it is positioned with the housing 1 by a positioning pin 11. Figure 4 As shown, when not in use, the positioning pin 11 is pulled out and the antenna bracket 3 is folded.

[0029] The positioning and orientation device is connected to two antennas 4, and two antenna brackets 3 are correspondingly provided on the shell 1. After the two antenna brackets 3 are unfolded, the angle between the connecting line of the two antennas 4 and the emission axis of the laser rangefinder 12 is equal to the preset angle and remains unchanged during use.

[0030] In order to facilitate disassembly and installation, the shell 1 is connected to the laser rangefinder 12 through a plug-in structure, that is, a dovetail groove 9 is provided on the upper side of the shell 1, and a dovetail 8 of the same type as the dovetail groove 9 is provided on the laser rangefinder 12. The dovetail groove 9 is inserted during installation. A dovetail 8 is provided on the lower side of the shell 1 for connecting other equipment.

[0031] The display and control device includes an integrated display 2 and buttons 5, both of which are connected to the processor. The buttons 5 include a power button, input buttons (such as function selection keys, up, down, left, and right selection keys), etc. The display 2 is used to display the target coordinates, standing point coordinates, target distance, target azimuth, and target elevation angle.

[0032] The processor has a built-in target coordinate calculation program, which is similar to the calculation program in the standard digital target reconnaissance and locating device. It calculates the target coordinates through the target distance, target azimuth, target elevation angle and standing point coordinates.

[0033] The method for positioning using the above device is as follows:

[0034] Step 1: Receive the standing point coordinates and target azimuth measured by the positioning and orientation device, the target elevation angle measured by the angle sensor, and the target distance measured by the laser rangefinder;

[0035] Step 2: Calculate the target coordinates according to the preset target coordinate solution model and send them to the display control device for display.

[0036] The above-mentioned device is directly connected to the laser rangefinder 12, and obtains the target position coordinates by measuring the target distance, standing point coordinates, target azimuth and target elevation angle through the laser rangefinder 12, the positioning and orientation device, and the angle sensor, thereby turning the laser rangefinder 12 into a high-performance target reconnaissance and positioning instrument, effectively improving the battlefield reconnaissance capability of the troops. Compared with the replacement of standard digital target reconnaissance and positioning instruments, it can save a lot of money for the troops and has higher target positioning accuracy. At the same time, the above-mentioned device can share power supply and target distance with the laser rangefinder 12, and has a simple structure, small size, low cost and easy operation.

[0037] The above device is an independent device that integrates target azimuth, elevation angle measurement, standing point positioning, target distance reception, and target coordinate solution. It only needs to be connected to the laser rangefinder by plugging and unplugging.

[0038] 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 scope of protection of the present invention.
