Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ammunition fuze information setting, in particular to a satellite guidance two-dimensional correction fuze wireless and wired setting device. BACKGROUND

[0002] In the use of satellite guidance missile, setting is an indispensable link. The user must write target parameters and ephemeris parameters into the setting device, and some must write the action mode, so that the satellite guidance missile can attack the predetermined target according to the predetermined mode. After the guidance ammunition is launched and powered on, the setting information is read, the hot start positioning is realized according to the ephemeris parameters, and the trajectory is corrected in time according to the real-time positioning information and target parameters to ensure that the ammunition can hit the target, and the near-blast, trigger or delay function is realized according to the set action mode.

[0003] Generally, one setting device is responsible for the setting of satellite guidance ammunition of one gun or even one artillery position. Therefore, the setting device needs to be small in size, light in weight and easy to carry, and easy to operate, preferably used in the night light condition. At the same time, the reliability of the setting device must be ensured, especially after experiencing various service environments, the setting device must not have any failure that affects the use.

[0004] At present, the satellite guidance missile setting device used by the artillery is large in size, heavy in weight and complex in operation, and it is difficult to realize single soldier operation. At the same time, most of the current satellite guidance missile setting devices use wired setting, which is not convenient to operate and difficult to set in the case of insufficient light at night.

[0005] If wireless setting is used, there are the following problems. First, the power supply problem during fuze setting. The fuze can only write setting information under the condition of power on. The wireless setting mode is redundant when using wired power supply. Wireless power supply must consider the energy transmission mode, and try to achieve simple structure, high reliability and low cost. Second, the anti-interference problem during setting. The wireless communication mode similar to NFC has the advantages of good anti-interference ability and the disadvantage of short communication distance, so the fuze can only be set one by one. The wireless communication mode such as Bluetooth and WIFI has the advantages of long communication distance and the ability to set all the fuses in a certain range at a time, and the disadvantage of being easily disturbed. Finally, the review problem of setting state. For the traditional fuze set by mechanical structure, the setting state of the fuze can be confirmed by the position and identification of the setting mechanism. For the fuze set by circuit, it is difficult to identify the setting state of the fuze from the appearance, so a means to quickly confirm the setting information of the fuze set by circuit is needed. SUMMARY

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] A satellite-guided two-dimensional correction accelerator wireless and wired setter and setter method, including a setter unit, an operating handle and a peripheral interface 5, and a housing 9 connecting the three together;

[0032] The mounting unit includes, in sequence, a display component, a main control component 6, and a coil component 4; it also includes a satellite positioning module 8 disposed at the end of the main control component 6;

[0033] The display component includes a buffer pad and a display screen 7. The display screen 7 is mounted on the housing 9 via the buffer pad. The display screen 7 is used to display the required installation information, satellite positioning module 8 information, operation progress and status.

[0034] The content on display screen 7 is mainly divided into three parts. The first part is the information to be installed, including the target's latitude and longitude and the tab for the mode of operation; the second part is the information of satellite positioning module 8, including the current location's latitude and longitude, signal strength, PDOP value, BeiDou time, visible / used satellites, ephemeris retention time, and tabs for extracting and clearing ephemeris; the last part is the notification bar, which mainly displays the progress and status of each operation.

[0035] The main control component 6 includes a main control board and a control box. The main control board is located inside the control box and has a control circuit. The control circuit is connected to the display component, the coil component 4, and the satellite positioning module 8. It is also connected to the operating handle and the peripheral interface 5. It is responsible for power distribution, information interaction, and logical operation functions.

[0036] The main control board is encapsulated in the control box with epoxy resin. This can prevent components from being damaged or solder joints from coming off due to accidental impacts, and can also prevent short circuits caused by foreign objects or oxidation of solder joints due to moisture. This can better protect the circuit and improve the reliability of the accelerator.

[0037] Coil component 4 includes an induction bracket, a coil cover, and an induction coil; it is used to exchange data with the fuse receiver during timing.

[0038] When installing the coil component 4 of this invention, silicone is also applied around the induction bracket to ensure the sealing inside the setter and improve the reliability of the setter in humid and desert areas. The coil cover is directly connected to the induction bracket by threads, and the induction coil is directly fixed in the groove on the coil cover by silicone. They also need to be sealed with silicone during installation to ensure airtightness and prevent loosening.

[0039] The operating handle includes a power supply unit 1 and an operating unit 2; the power supply unit 1 includes a lithium battery and a protection circuit, which is used to power the setter; the operating unit 2 includes an operating keyboard and an LED light 3; the operating keyboard is used to realize all operations of setting the fuse; the LED light 3 is used to display the working status of the setter.

[0040] Peripheral interface 5 includes two connectors. One connector is used to charge the power supply component 1 and to program the main control component 6. The other connector is used to directly communicate with the main control component 6 of the fuse via a wired setting line to complete the setting in the event of wireless setting failure.

[0041] The satellite positioning module 8 includes a satellite receiver, an antenna, and an antenna cover; the satellite positioning module 8 is used to automatically or manually enter the satellite search mode after the setter is powered on.

[0042] By combining the operating handle and peripheral interface 5, information can be set for the fuse in both wireless and wired modes.

[0043] In this embodiment, in order to protect the antenna without interfering with its normal operation, polyurethane foam is filled between the antenna and the radome.

[0044] The main function of satellite positioning module 8 is to automatically begin satellite search after the accelerator is powered on. If the accelerator has not extracted the ephemeris, the satellite receiver will enter a cold start satellite search mode, which typically takes 30 to 40 seconds to successfully locate the satellite and for the PDOP value (a measure of positional accuracy) to be less than a specified range. If the accelerator has already extracted the ephemeris, the satellite receiver will begin a warm start satellite search based on this ephemeris. If the ephemeris is not expired, a warm start satellite search usually takes only 3 to 5 seconds. If the ephemeris has expired and the satellite receiver fails to locate the satellite within 10 seconds, it will automatically switch back to cold start satellite search mode. Once satellite positioning module 8 successfully locates the satellite and the PDOP value is less than the specified range, the cursor can be moved to the "Extract Ephemeris" tab using the left and right arrow keys, and the confirmation key can be pressed to extract the ephemeris file for accelerator use.

[0045] The brightness of the display screen 7 used in this invention can be freely adjusted according to the user's needs. It can be used in direct sunlight during the day or in controlled lighting conditions at night; all content on the display screen 7 is clearly displayed.

[0046] During setup, the flashing and constant illumination of three LEDs allow for quick and convenient confirmation of the setter's working status and setup success, facilitating the confirmation of the fuse's setup status. After each setup, the setup information is automatically saved to the current state, and upon restarting, it restores to the state before the last shutdown, eliminating the need to re-enter the target coordinates and select the action mode, thus improving ease of use.

[0047] The wireless setting uses the principle of near-field inductive communication. If the angle or distance between the transmitting coil 11 and the receiving coil 10 is too large, it will lead to a decrease in energy transmission efficiency and a reduction in the reliability of information interaction. However, the present invention can greatly improve the anti-interference capability during setting.

[0048] This setter can still use the wired setting function if the wireless setting fails. To use it, simply insert one end of the wired setting cable into the setting interface of the setter, and the other end into the setting interface on the fuse. After entering the setting parameters, click the setting button to complete the setting. This working mode, with wireless setting as the primary method and wired setting as a backup, ensures both ease of use and improved reliability.

[0049] When using wireless power supply, the energy radiated by the coil is limited, only enough to power the wireless communication chip and peripheral circuits. Other modules on the main control board remain unpowered, preventing the deactivation and ignition capacitors from charging and thus avoiding accidental activation of the pyrotechnic device during assembly. When using wired power supply, the assembler only supplies 5V to the main control board, causing most circuits to operate and the deactivation and ignition capacitors to charge. However, for reliable pyrotechnic device operation, the capacitors need to be charged to at least 9V. Therefore, using 5V power supply also prevents accidental activation during assembly. This improves safety during assembly and minimizes the impact on fuse reliability.

[0050] Furthermore, if the setting fails under either of the above two conditions, simply re-align the setter. Therefore, compared to wired setting, which requires removing the protective cap from the communication interface on the fuse and then connecting the setting wire to the communication interface before setting, wireless setting, which can be achieved with just a touch and a press, has a significant advantage in terms of convenience, especially in low-light conditions at night.

[0051] The mounting method used in this invention includes the following steps:

[0052] S1. Press the power switch on the operating handle to turn on the setter.

[0053] S2. Use the directional keys on the control handle to move the cursor on display 7 to the Clear Ephemeris tab, then press the OK key. Wait for the notification bar on display 7 to pop up that the ephemeris clearing was successful, then wait 10 seconds or restart the setter to start the cold start satellite search. When searching for satellites, choose an open outdoor area.

[0054] S3. When satellite positioning is successful and the PDOP value drops to the specified range, the yellow light in the middle of LED 3 will stop flashing and the green light on the right will start flashing, indicating that the ephemeris can be extracted. Move the cursor to the extract ephemeris tab, press the confirm button, and wait for the notification bar to pop up that the ephemeris extraction is complete, indicating that the ephemeris information is ready.

[0055] When the satellite positioning module 8 is searching for a satellite but has not successfully located it, or has located it but the PDOP value is greater than or equal to a specified range, the yellow light in the middle will flash to indicate that the ephemeris cannot be extracted temporarily. When the satellite positioning module 8 successfully locates the satellite and the PDOP is less than the specified range, the yellow light in the middle will stop flashing, and the green light on the right will start flashing to indicate that the ephemeris can be extracted. When the setting key on the operation keyboard is pressed, the coil component 4 starts to work and transmits setting information. If the information transmission is completed and the verification is correct, the green light will stay on for 2 seconds to indicate that the setting is successful. Otherwise, the red light will stay on for 2 seconds to indicate that the setting has failed.

[0056] When wireless setting fails, insert one end of the wired setting cable into the connector setting interface for information interaction in the peripheral interface 5 of the setting device, and insert the other end into the setting interface on the fuse. After inputting the setting parameters, click the setting button to complete the setting.

[0057] S4. After the ephemeris information is prepared, move the cursor to the target information and input the latitude, longitude and altitude coordinates of the target using the number keys and decimal point keys on the control handle. The input is automatically verified.

[0058] S5. Next, move the cursor to the Action Mode tab, select the desired action mode, and press the OK button.

[0059] S6. After confirming that the above setting information is correct, align the setting coil cover with the wind cap of the fuse 12 to be set, and press the setting button.

[0060] S7. After the notification bar pops up with a notification that the fuse has been successfully installed and the green light stays on for 2 seconds, it means that the fuse has been successfully installed.

[0061] S8. After the fuze is successfully set, move the cursor to the "Read Fuze" tab, press the "OK" key to read the fuze setting information, and verify the fuze setting information with the setting information of the assembler to ensure the reliability of the setting.

[0062] The above-mentioned information is automatically saved to the current state. When the device is turned on again, it will be restored to the state before it was turned off, without the need to re-enter the target coordinates and select the mode of operation.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
