[0040] In this embodiment, the control mechanism 4 is mainly composed of a central control host 41, an in-vehicle centralized controller 42, an in-vehicle display 43, an outside left controller 441, and an outside right controller 442. The central control host 41 is arranged under the rear passenger compartment to facilitate the matching arrangement, wiring, and maintenance of the controlled equipment, and a chassis protection is set on the outside; the in-vehicle centralized controller 42 and the in-vehicle display 43 are arranged in the driver and co-driver compartments. The in-vehicle centralized controller 42 is fixed with a card-type bracket, which can realize two operation modes of vehicle-mounted fixed and handheld mobile, and is used to centrally control the telescopic lifting and lifting of the assault platform and the front camera lens; the in-vehicle display 43 is fixed with a rotating bracket, and the rotatable structure design is convenient for the driver and co-driver to observe separately and realize the surrounding situation awareness. The control mechanism 4 takes the central control host 41 as the center, and constructs a closed-loop control circuit of operating elements, control elements, execution elements, and state perception elements. The control operation of each device is realized by converting the operating element signal, issuing the control command of the control element, and executing the operation after receiving the control command. The operating elements are mainly the in-vehicle centralized controller 42, the outside left controller 441, and the outside right controller 442. 42, the operation command through human-computer interaction is converted into an electrical signal; the control element is the central control host 41, which issues control commands to the execution element according to the preset program by accessing various communication COM, RS232 bus serial ports, pressure switches and operation commands and other information; the execution elements are various relays 49, hydraulic solenoid valves 321, motor switches, etc., which realize the action and state adjustment of equipment such as the lifting slope 241, the extension slope 242, and the stabilizing leg 26 after receiving the control command. The state sensing element is the in-vehicle display 43, and the video information around the vehicle and the top of the assault truss is presented on the display 43 to realize the surrounding situation awareness and provide a convenient, fast and reliable operation method for on-site operators. The assault truss mechanism 2 has multiple dimensions of movement, and the operator can control the assault truss at different positions under different circumstances. The solution has two operation modes: cab operation and platform operation; the two operations have an interlocking function, that is: when one operation has started, the other operation command becomes invalid until the current operation is completed, which is achieved through the control priority of the touch system in the vehicle and the handheld control outside the vehicle to ensure operation safety. The CPU system identifies that if either party inside or outside the car presses the action key first, it will automatically authorize the priority operator, and the other party will be automatically locked and cannot operate. After 3 seconds, the system detects no operation and automatically unlocks the system. The system continues to detect the priority between inside and outside the car. The control mechanism 4 flattens all function controls and reduces the operation level. It fully considers the controllability requirements of human-computer interaction in various scenarios, and fully decomposes each function and usage target of the equipment into independent interaction elements, which not only ensures the operator's autonomous control of each device and function, but also ensures efficient and convenient integration of operations.

[0041] In order to better understand the present invention, the following Figures 1 to 7The technical solution of the present invention is described in detail: the control mechanism 4 adopts an embedded real-time operating system, and uses a multi-task parallel processing method to flatten all functional controls, reduce the operation level, and enable each task to be executed within a certain time period, thereby ensuring the real-time performance of the system. Make full use of the processing power of the CPU, assign different priorities to different tasks, so that some key tasks can be processed in a timely manner with priority, and ensure safe operation; the centralized controller 42 inside the car and the left controller 441 and the right controller 442 outside the car have an interlocking function, and the touch control system inside the car and the handheld controller outside the car both have control priority. The centralized controller 42 inside the car communicates with the central control host through RS232 to realize the sending of control instructions, and the left controller 441 or the right controller 442 outside the car realizes the sending of control instructions through a combination of switch pulses and time periods. When the central control host receives commands from both parties, the CPU automatically authorizes the priority operator to automatically lock the other party and cannot control it through system recognition. If it does not control it, it will automatically unlock after a delay of 3S, and the system continues to detect the priority between inside and outside the car;

[0042] In terms of the hardware of the control mechanism 4, the centralized controller 42 inside the vehicle is arranged at the co-pilot position and is movable and handheld for easy handheld operation; the left controller 441 and the right controller 442 outside the vehicle are arranged next to the rear seats for easy operation by the rear passengers, and emergency stop switches 48 are added on both sides of the rear assembly platform 244. When there is an abnormal situation, press the emergency stop button on any side of the left controller 441 and the right controller 442 outside the vehicle, and the centralized controller 42 inside the vehicle and the left controller 441 and the right controller 442 outside the vehicle will not be able to control the action of the front assault platform 24, effectively realizing and maintaining emergency stop in any state.

[0043] The assault truss mechanism 2 is a front assault platform 24 on the left and right sides. The front assault platform 24 is composed of four devices, namely, a lifting slope 241, an extension slope 242, a stabilizing leg 26 and a camera 411. Each device is decomposed into a command. At the same time, a one-key light synchronization function is added according to the usage scenario, so that the independent controllability of the device is achieved and the functional accessibility is guaranteed.

[0044] While performing the above operations, the centralized controller 42 in the vehicle will display the current option color change and key tone reminder to ensure feedback of the operation action. The in-vehicle display 43 also has the situation awareness function around the front assault platform 24, and fully decomposes each function and use target of the equipment into independent interactive elements, which not only ensures the operator's independent control of each device and function, but also ensures the efficient and convenient integration of operations, and the display and control operations are highly coordinated. When designing the system and equipment, the control mechanism 4 fully considers the human-computer interaction in various scenarios and adopts the WI MP model design. Compared with the command line interface, the naturalness and efficiency of the human-computer interaction of the graphical user interface are greatly improved.

[0045] The lifting angle analysis of the lifting slope 241 is as follows: the assault platform is hinged to the truss body 21 at point K; the support arm 34 is hinged to the truss body 21 at point O; the lifting cylinder 41 is hinged to the support arm 34 and the truss body 21 at points A and C respectively. When the lifting stroke of the lifting cylinder 41 reaches the maximum, the lifting slope 241 reaches the maximum lifting angle; the calculation formula of the front climbing height is: H = h1 + h2 + h3 = h1 + L1 × sinα + L2 × cosβ, the front climbing height of the front assault platform 24 is H, the side climbing height of the front assault platform 24 is H1, and the front climbing height H includes h1, h2 and h3, where h1 is the height of the rear assembly platform 244, h2 is the climbable height of the assault platform when deployed, h3 is the climbable height of the tactical ladder 251, the lifting angle of the front assault platform is α, the placement angle of the tactical ladder 251 is β, the length of the front assault platform is L1, and the length of the tactical ladder 251 is L2; ​​the calculation formula for the side climbing height is H1=h3+h4=h3+L3×cosγ, and the side climbing height H1 can be divided into two sections, h3 and h4, where h3 is the height of the sliding side rails 23 on both sides of the truss body 21, h4 is the climbable height of the tactical ladder 251, and the tactical ladder 251 mounting angle is γ The length of the tactical ladder 251 is L3. The present application sets the skeleton of the truss body 21 as an eight-shaped trapezoidal structure and is provided with multiple oblique reinforcing beams to form a stable triangular structure with the truss skeleton and the lifting arm skeleton. Two stabilizing legs 26 are arranged at the front of the truss, which can effectively ensure the stability of the whole vehicle when the center of mass moves forward during lifting and forward projection. In addition, by setting functional accessories such as the tactical ladder 251, the assault ladder 252, and the rotating tower plate 253, each accessory adopts a quick-insert structure and can be used alone or in conjunction with the assault truss system to extend the assault surface or form a assault surface, so that personnel can be deployed from multiple people, multiple levels, multiple angles, and multiple directions. Transport to the designated position to improve mobility. The hydraulic mechanism 3 is the power source of the assault truss system. The oil circuits of the hydraulic system cylinders of the lifting, extension and stabilizing legs 26 are connected in parallel, which are independent and do not interfere with each other. The action of each cylinder is controlled by a control circuit connected to an electromagnetic reversing valve, which is convenient for operation. The control mechanism 4 is composed of an in-vehicle centralized controller 42 and an out-vehicle controller 44, and has two control modes inside and outside the vehicle; and the principle of first-control priority interlocking is adopted, and there is an interlocking function between the double controls, that is, when one operation has started, the other operation command becomes invalid until the current operation is completed. The control is flexible and efficient with high safety.

[0046] This technical solution realizes the movement of various equipment through a stable mechanical structure design combined with a hydraulic system and an electric control system. It has the characteristics of rapid maneuverability, efficient climbing, stability and reliability.
