Description

Technical Field

[0001] The present invention relates to the technical field of light weapons, and in particular to a universal shooting control device based on a steering gear. Background Art

[0002] With the harsh and complex combat environment and various unexpected threats in modern warfare, as well as the maturity of technologies of light unmanned platforms such as drones and unmanned vehicles, unmanned battlefields are the trend of the future. In order to carry various weapons, unmanned platforms need to design more reasonable shooting control devices and weapon linkages.

[0003] Currently, most traditional electric-controlled firing mechanisms use an electromagnet to attract the trigger, but the electromagnet is heavy and consumes high power, which will add a large load to the carrying platform and reduce the continuous working time. It is not suitable for light unmanned platforms. At the same time, the electromagnet has a long reaction time, low sensitivity, and poor shooting effect. Summary of the invention

[0004] The purpose of the present invention is to provide a universal shooting control device based on a servo, which can control a firearm to shoot and has the advantages of small size, light weight and good shooting accuracy.

[0005] To achieve the above-mentioned object, the present invention provides a universal shooting control device based on a servo, comprising a power module, a core circuit board, a proximity sensor, a first digital servo and a second digital servo;

[0006] The core circuit board is connected to the power module, the proximity sensor is connected to the core circuit board, the first digital servo is connected to the core circuit board, and the second digital servo is connected to the core circuit board.

[0007] Wherein, the universal shooting control device based on the servo also includes a control software module; the control software module is connected to the core circuit board.

[0008] The core circuit board adopts a GD32F103RCT6 microprocessor, which is used to control the operation mode of the first digital servo and the second digital servo, realize the switching of the safety and shooting modes of the firearm, and the action of pulling the trigger.

[0009] The proximity sensor is used to sense the position of the automatic gun machine, and send a signal to the core circuit board to realize the shooting count, and feedback the shooting status and the number of remaining bullets.

[0010] The first digital servo is used to pull the trigger of the firearm to fire the firearm.

[0011] Among them, the second digital servo is used to rotate the safety, single shot, and continuous fire knobs of the firearm to achieve the switching of the firearm safety, single shot, and continuous fire.

[0012] The present invention discloses a universal shooting control device based on a steering gear. The core circuit board adopts a GD32F103RCT6 microprocessor, is equipped with a serial port transceiver and a CAN bus transceiver module, an optical coupling isolation I0 module, and a power module. The core circuit board has the characteristics of low power consumption and high operating frequency, and meets the national production demand of military electronic components. The core circuit board provides a stable power supply processed by the power module for the first digital steering gear and the second digital steering gear, and provides power for the proximity sensor at the same time, collects feedback level signals, and inputs them into a main control chip for shooting counting after optical coupling isolation processing. The core circuit board has two PWM pulse outputs, which respectively control the first digital servo and the second digital servo. The second digital servo is used to rotate the safety, single shot, and continuous firing knob of the firearm to realize the switching of the firearm safety, single shot, and continuous firing. The first digital servo is used to pull the trigger of the firearm to realize the firing of the firearm. The universal shooting control device establishes communication with the unmanned platform through the serial port or CAN bus. According to the command of the unmanned platform, the duty cycle of the PWM pulse sent to the second digital servo is changed, and the second digital servo rotates 0°, 90°, and 180° in turn to drive the movement of the safety switching knob to realize the switching of safety, single shot, and continuous firing. In the single shot or continuous firing state, the universal shooting control device receives the shooting command issued by the unmanned platform, immediately changes the duty cycle of the PWM pulse of the first digital servo, makes it run backward at a fixed angle, completes the action of pulling the trigger, and immediately resets when the command to stop shooting is obtained. If it is in the safety state, it will not execute the action even if the shooting command is received, so as to ensure the safety of the firearm. During the shooting process, the automatic machine of the firearm will reciprocate in the receiver. Whenever the automatic machine moves to the proximity sensor at the end of the firearm, it will be induced to generate a level signal. The universal shooting control device collects the signal to realize the shooting count. Combined with the number of loaded ammunition set in the communication command, the remaining amount of ammunition can be calculated by subtraction and fed back to the unmanned platform. The custom communication protocol can expand the information interaction content between the unmanned platform and the universal shooting control device by adding and subtracting commands, such as modifying the initially set PWM pulse duty cycle to adapt to different weapons. This application can control the firearm to shoot, and has the advantages of small size, light weight and good shooting accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In this embodiment, the core circuit board 2 adopts a GD32F103RCT6 microprocessor, equipped with a serial port transceiver and a CAN bus transceiver module, an optical coupling isolation I0 module, and a power module 1. It has the characteristics of low power consumption and high operating frequency, and meets the national production requirements of military electronic components. The core circuit board 2 is a prior art. When in use, the core circuit board 2, the proximity sensor 3, the first digital servo 4 and the second digital servo 5 can be connected according to the model of the product. The core circuit board 2 provides a stable power supply processed by the power module 1 for the first digital servo 4 and the second digital servo 5, and provides power for the proximity sensor 3, and collects the feedback level signal, which is processed by optical coupling isolation and input into the main control chip for shooting counting. The core circuit board 2 has two PWM pulse outputs, which control the first digital servo 4 and the second digital servo 5 respectively. Figure 3Taking a submachine gun as an example, the second digital servo 5 is used to rotate the safety, single shot, and continuous firing knob of the firearm to realize the switching of the firearm safety, single shot, and continuous firing. The first digital servo 4 is used to pull the trigger of the firearm to realize the firing of the firearm. The universal shooting control device establishes communication with the unmanned platform through the serial port or CAN bus. According to the command of the unmanned platform, the duty cycle of the PWM pulse sent to the second digital servo 5 is changed, and the second digital servo 5 rotates 0°, 90°, and 180° in turn to drive the movement of the safety switching knob to realize the switching of safety, single shot, and continuous firing. In the single shot or continuous firing state, the universal shooting control device receives the shooting command issued by the unmanned platform, immediately changes the duty cycle of the PWM pulse of the first digital servo 4, makes it run backward at a fixed angle, completes the action of pulling the trigger, and immediately resets when the command to stop shooting is obtained. If it is in the safety state, it will not execute the action even if the shooting command is received, thereby ensuring the safety of the firearm. During the shooting process, the automatic machine of the firearm will reciprocate in the receiver. Whenever the automatic machine moves to the proximity sensor 3 at the rear end of the firearm, it will be sensed to generate a level signal. The universal shooting control device collects the signal to realize the shooting count. Combined with the number of loaded ammunition set in the communication command, the remaining amount of ammunition can be calculated by subtracting the two and then fed back to the unmanned platform. The custom communication protocol can expand the information interaction content between the unmanned platform and the universal shooting control device by adding and subtracting commands, such as modifying the initially set PWM pulse duty cycle to adapt to different weapons.

The control software module 6 has both serial communication and CAN bus communication modules, and can output two PWM pulses, and controls the first digital servo 4 and the second digital servo 5 through the core circuit board 2. According to the instructions received by the communication module, the safety, single shot, and continuous shot are switched, and the trigger is pulled to shoot, and the proximity sensor 3 signal is collected to determine the position of the automatic machine, and the shooting count is performed, and the shooting status, the number of remaining bullets and other information are fed back. The communication module adopts interrupt reception to ensure real-time performance. It supports custom communication protocols, performs more information interaction, and adapts to various unmanned platforms to ensure universality.
