Description

Technical Field

[0001] The invention relates to a vehicle-mounted photoelectric measurement cabin, in particular to an unattended vehicle-mounted photoelectric measurement equipment movable cabin which can be automatically unfolded and retracted. Background Art

[0002] Photoelectric measurement equipment is a measurement equipment that can quickly capture targets, accurately track targets, transmit real-time images, and replay images in modern shooting ranges. It is mainly used to record test parameters such as target motion trajectory data, flight attitude, and radiation characteristics, and is widely used in aviation, aerospace, and test shooting ranges. After the 1990s, photoelectric measurement equipment has mostly adopted a vehicle-mounted structure, that is, the vehicle body is used as a carrier and equipped with photoelectric instruments to carry out measurement work.

[0003] There are two ways to use vehicle-mounted photoelectric measurement equipment. The first way is vehicle-mounted ground measurement, that is, when performing a task, the photoelectric measurement equipment is loaded on a vehicle and transported to the measurement point. After unloading, it is installed on a pre-prepared foundation ring. After the task is completed, it is reloaded, and the equipment is transported on a vehicle, which improves the utilization rate of the equipment. However, the usage mode is still fixed on the foundation and has not gotten rid of the fixed point restriction. The other way is vehicle-mounted non-ground measurement, that is, the support platform is detached from elastic links such as tires through outrigger support and other methods. The instrument works directly on the support platform, and the equipment is leveled, positioned and oriented without landing before measurement is carried out. Its strong mobility can realize real-time capture, tracking and measurement at different times and places, rapid deployment and rapid withdrawal, eliminating the need for stationing points, and returning immediately after completing the task. It significantly improves the rapid response capability of photoelectric instruments and has become the most important method of use at present.

[0004] In certain specific measurement conditions, such as live recording of spacecraft launches, target characteristic measurements, and target event capture under high electromagnetic radiation, the measurement equipment may cause harm to the on-board operator. In this case, a remote unattended method is required to operate the optoelectronic measurement equipment. However, when the existing on-board measurement equipment, especially the mobile cabin, is used in the field, it needs to be manually opened and pushed and pulled to the designated position of the fixed cabin to be fixed, so that the equipment can be fully exposed to the external environment before the test task can be carried out. When encountering sudden weather environments such as sandstorms or rainy days, the unattended optoelectronic measurement equipment exposed to the environment is prone to electrical system short circuits, dust or corrosion of optical lenses, and mechanical component jamming or rusting due to the inability to close the mobile cabin in time, which seriously affects the service life of the equipment and even causes equipment failure. The losses in measurement tasks and economy are immeasurable. Therefore, it is urgent to carry out the optimization design of the mobile cabin under unattended working conditions in the field, so that when encountering sudden weather such as sandstorms, thunderstorms, etc., the withdrawal work can be completed quickly, thereby protecting the safety of the optoelectronic measurement equipment.

[0020] 1. High degree of automation: When the on-board photoelectric measurement equipment is powered on, the door locking assembly is first powered on to automatically release the closed state of the right and left doors. Secondly, the left and right door electric rotation assemblies use the power provided by the revolving door motor to realize the automatic opening of the right and left doors, and rely on the photoelectric signal to determine the final opening position, and then use the door locking assembly to fix the right and left doors in the open position, which can effectively prevent the right and left doors from shaking randomly due to wind load.

It can be seen that the deployment action of the square cabin is all electrically operated, with a high degree of automation and no human participation. Similarly, the withdrawal action of the square cabin can be realized by electric control using the same logic. At the same time, the movable cabin electric push-pull assembly and the left and right door electric rotation assembly are designed with a travel limit structure relying on a photoelectric switch, which improves the safety of the automatic operation of the assembly.

[0021] 2. Strong adaptability to the working environment: In response to the unmanned equipment requirements mentioned by most shooting range users, the vehicle-mounted optoelectronic measurement equipment can automatically deploy and retract the activity cabin through remote control, which can conveniently realize the automatic deployment and retraction of the activity cabin. It can well cope with sudden weather conditions such as sandstorms or rainy days, and provide timely and effective protection for optoelectronic measurement equipment.

[0022] 3. Ability to work in rainy days without human supervision: The laser ranging sensor can obtain the position of the shelter in real time, and accurately calculate the deployment position of the optoelectronic measurement equipment in the shelter without rain according to the shape and position relationship between the shelter and the equipment. It can also calculate the azimuth and pitch angles that the shelter can observe in a semi-open state according to the acquired position information, thereby guiding the implementation of field observation tasks.

[0023] 4. Good performance: The push-pull guide rail assembly of the movable cabin achieves point-to-surface contact through the ball bearings to reduce the push-pull friction resistance of the movable cabin, effectively prevent the problem of jamming, and play a rough guiding role. At the same time, the auxiliary guide assembly of the movable cabin cooperates with the electric push-pull assembly of the movable cabin and the push-pull guide rail assembly of the movable cabin to play a precise guiding role, thereby ensuring the good performance of the push-pull of the square cabin. Furthermore, the left and right door electric rotation assemblies and the door locking assemblies cooperate to complete the opening, closing and locking functions of the left and right doors. The operating actions have a clear logical relationship, there are no risk points in the operation process, and the safety and reliability are high. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] like Fig.17 As shown, the door locking assembly 13 includes a brake mounting seat 34, a power-off lock brake stator 35, a brake spring 36, a power-off lock brake mover 37, a fixing pin 38 and a fixing pin mounting seat 39; wherein, two brake mounting seats 34 are mounted on the top wall 5, and the other two brake mounting seats 34 are respectively mounted on the left door 7 and the right door 8; the four power-off lock brake stators 35 are respectively mounted on the four brake mounting seats 34, and each power-off lock brake stator 35 is designed with 6 evenly distributed threaded holes, and a guide column is arranged at the center of the threaded hole; each power-off lock brake stator 35 is electrically controlled by the movable cabin deployment and retraction control system; the brake spring Both ends of the spring 36 are provided with flanges with center holes, and the flange located at the upper end of the brake spring 36 is designed with external threads; four sets of fixed pin mounting seats 39 are respectively installed on the fixed cabin 2, the left cabin door 7 and the right cabin door 8 at positions corresponding to the brake mounting seats 34, and four sets of fixed pins 38 are respectively installed on the four sets of fixed pin mounting seats 39 by screws; the fixed pin 38 is designed with a center hole with a 45° chamfer, and the power-off lock brake mover 37 is designed with a guide column with a 45° cone surface; in the power-off state, the brake spring 36 uses elastic force to press the guide column of the power-off lock brake mover 37 into the center hole of the fixed pin 38, so that the left cabin door 7 and the right cabin door 8 can be reliably closed. The brake spring 36 is installed at the outer side of the power-off lock brake stator 35, which can improve the anti-bending ability of the power-off lock brake mover 37 when receiving external force, and further enhance the reliability of the closure of the left cabin door 7 and the right cabin door 8;

[0054] In addition, the positions of the power-off lock brake movers 37 on the left wall 6 and the right wall 9 corresponding to the opened left door 7 and the right door 8 are also respectively installed with fixing pin mounting seats 39, and the fixing pin 38 is installed on the fixing pin mounting seats 39 by screws; Fig.18 As shown, when the on-board photoelectric measuring equipment is to be powered on, the left door 7 and the right door 8 are automatically opened, and a suction force is generated between the power-off lock brake stator 35 and the power-off lock brake mover 37, and the brake spring 36 contracts along the guide column of the power-off lock brake stator 35, driving the power-off lock brake mover 37 to move, so that the matching relationship between the center hole of the fixing pin 38 and the guide column of the power-off lock brake mover 37 is released; Fig.18 As shown, when the left door 7 and the right door 8 are automatically opened 270° from the closed position to the predetermined position, the left and right door electric rotation components 12 stop moving after receiving the limit signal of the photoelectric switch 29.

[0055] When used in the field, the movable cabin 1, the fixed cabin 2 and the vehicle chassis 3 together form the vehicle-mounted structure of the photoelectric measuring device 4, that is, the vehicle body is used as a carrier to carry out the measurement work with the photoelectric instrument. Fig.19 As shown, the specific working process of opening the activity cabin 1 is as follows:

[0056] Step 1: The mobile cabin is deployed, the control system is powered on, the system is self-checked and each I / O port is initialized;

[0057] Step 2: The control system for deploying and retracting the movable cabin sends a command to the control module of the cabin door locking assembly to control the stator 35 of the power-off lock brake to pull the mover 37 of the power-off lock brake upward. At this time, the guide column on the mover 37 of the power-off lock brake is disengaged from the fixing pin 38, so that the left cabin door 7 and the right cabin door 8 are unlocked;

[0058] Step 3, the control system for deploying and withdrawing the movable cabin sends a command to the control module of the electric rotating assembly of the left and right doors to control the power supply of the rotating door motor 20 to realize the automatic opening of the left door 7 and the right door 8; when the light shielding sheet on the limit stopper 27 blocks the photoelectric switch A29, the photoelectric switch A29 sends a signal to the control module of the electric rotating assembly of the left and right doors to control the rotating door motor 20 to stop working;

[0059] Step 4: The control system for deploying and withdrawing the movable cabin sends a command to the cabin door locking assembly control module to control the power-off lock brake mover 37 to disengage from the power-off lock brake stator 35. At this time, the guide column on the power-off lock brake mover 37 falls into the fixing pin 38 provided at the corresponding position on the left wall 6 and the right wall 9, locking the left cabin door 7 and the right cabin door 8 in the 270° open position.

[0060] Step 5: The control system for unfolding and retracting the movable cabin sends a command to the control module of the movable cabin electric push-pull assembly to control the push-pull cabin motor 40 to be powered on, and the movable cabin auxiliary guide assembly 15 and the movable cabin push-pull guide rail assembly 11 cooperate to realize the automatic opening of the movable cabin 1; when the electric limit shading sheet 50 provided on the transmission nut 49 blocks the photoelectric switch B 47, the photoelectric switch B 47 sends a signal to the control module of the movable cabin electric push-pull assembly to drive the push-pull cabin motor 40 to stop working;

[0061] Step 6: The laser ranging sensor 52 feeds back the real-time position information of the movable cabin 1 to the movable cabin deployment and retraction control system, and the movable cabin deployment and retraction control system calculates the observation range in the open state.

[0062] The method of withdrawing the activity cabin 1 is the same as the above logic. Fig. 20 As shown in the calculation model, a Cartesian coordinate system is established with the intersection of the azimuth axis and the pitch axis of the photoelectric measurement equipment 4 as the origin O, and the vehicle length direction as the X-axis, the vehicle width direction as the Y-axis, and the vehicle height direction as the Z-axis; the optical load aperture carried by the photoelectric measurement equipment 4 is assumed to be D, and the distance between the optical axis of the optical load and the pitch center is assumed to be L.

[0063] If you want to obtain the azimuth angle and pitch angle that can be observed in the semi-open state of the mobile cabin 1, you need to know the coordinates (x, y, z) of the open outline of the mobile cabin 1 in the OXYZ coordinate system after the left cabin door 7 and the right cabin door 8 are opened. When the mobile cabin 1 is in a semi-open state, the Z-axis coordinate value z0 of the open outline of the mobile cabin 1 can be obtained by the laser ranging sensor 51. At the same time, the X-axis coordinate x0 and the X-axis coordinate y0 of the open outline of the mobile cabin 1 can be easily obtained according to the design model. Thus, the corresponding relationship between the observable azimuth angle α, the pitch angle β and the above parameters is established, as shown in the following formula:

[0064]

[0065] Since the distance x1 between the front end of the optical load and the origin O is fixed, the deployment position Δx of the movable cabin 1 when the movable cabin 1 is not initially deployed can be obtained according to the distance x2 between the movable cabin 1 and the origin O when the movable cabin 1 is not initially deployed. Assuming that the rain falls vertically, the following relationship can be obtained:

[0066] Δx=x2-x1

For ordinary professional and technical personnel in the field, the specific technical solutions recorded in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions protected by the present invention.
