Description

Technical Field

[0001] This invention relates to the field of automatic detection technology, and more specifically, to an environmental chamber collision avoidance system and method. Background Technology

[0002] An environmental chamber is a sealed test space with adjustable temperature, humidity, air pressure, and light. It is used for dynamic testing of small components or large-mass equipment, vehicles, etc. (collectively referred to as target equipment). In order to monitor the dynamics of the target equipment in the chamber in real time and prevent the target equipment from colliding with the chamber walls, a series of electrical components such as sensors are usually installed in the chamber to detect the position of the target equipment. However, under the test conditions of the environmental chamber, due to the harsh environment such as high temperature, low temperature, and high humidity, the electrical components may fail due to problems such as rust and circuit damage, which will affect the monitoring of the target equipment.

[0003] Therefore, how to provide a system that avoids the impact of extreme temperature and humidity in the environmental chamber on collision avoidance detection has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an environmental cabin collision avoidance system and its safety method, which can reduce the impact of extreme temperature and humidity conditions inside the cabin on electrical components outside the cabin.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: This invention provides an environmental cabin collision avoidance system, including a cabin body, a sealing mechanism, and a detection device. The cabin body includes a cabin wall that encloses an internal space. A restricted area is pre-defined within the internal space. A through channel is provided on the cabin wall, and the through channel is connected to the internal space at an opening. The sealing mechanism is located at the opening and can switch between a first position with the opening open and a second position with the opening closed. The detection device is located in the through channel. When the sealing mechanism is in the first position, the detection device is used to detect whether a target device exists in the restricted area.

[0006] Furthermore, the environmental chamber collision avoidance system also includes a drive mechanism connected to the sealing mechanism, which is used to drive the sealing mechanism to switch between a first position and a second position.

[0007] Furthermore, the environmental cabin collision avoidance system also includes a fixed bracket, which is set outside the cabin or in the through passage. The drive mechanism includes a main body and a movable part that can move linearly relative to it. The main body is rotatably connected to the fixed bracket, and the movable part is rotatably connected to the sealing mechanism.

[0008] Furthermore, the environmental chamber collision avoidance system also includes a hinge assembly, and the sealing mechanism and the bulkhead are connected by the hinge assembly.

[0009] Furthermore, the environmental cabin collision avoidance system also includes a reinforcing plate, which is ring-shaped and located around the outer periphery of the opening's outer contour. The reinforcing plate is situated between the hinge assembly and the cabin wall.

[0010] Furthermore, the environmental chamber collision avoidance system also includes a seal, which is located on the side of the sealing mechanism near the through passage. When the sealing mechanism is in the first position, the chamber wall and the sealing mechanism together clamp the seal.

[0011] Furthermore, the sealing mechanism includes a housing and an insulation layer, the housing having a hollow inner cavity, and the insulation layer being disposed within the hollow inner cavity.

[0012] Furthermore, the detection device includes: an alarm device; a laser detection mechanism disposed in the through channel, which is used to scan whether a target device exists in the restricted area when the sealing mechanism is in the first position; and a controller, which is communicatively connected to the drive mechanism, the alarm device and the laser detection mechanism respectively.

[0013] Furthermore, the environmental chamber collision avoidance system includes a hatch, and the bulkhead has an opening that communicates with the internal space. The hatch is located at the opening. The environmental chamber collision avoidance system also includes: a position sensor that is communicatively connected to the controller and capable of detecting the state of the hatch; and / or, the environmental chamber collision avoidance system includes a displacement sensor that is communicatively connected to the controller and capable of detecting the state of the sealing mechanism; and / or, the environmental chamber collision avoidance system includes a limit sensor that is communicatively connected to the controller and used to detect the state of the drive mechanism.

[0014] Furthermore, the laser inspection mechanism can generate an inspection surface that is parallel to the horizontal plane.

[0015] This invention also provides an environmental chamber collision avoidance method, applied to the environmental chamber collision avoidance system provided in the above embodiments. The environmental chamber collision avoidance system includes a door and a drive mechanism. The drive mechanism is connected to the sealing mechanism. The chamber wall has a hatch communicating with the internal space. The door is located at the hatch. The detection device includes a laser detection mechanism, an alarm device, a position sensor, a displacement sensor, a limit sensor, and a controller. The laser detection mechanism, alarm device, position sensor, displacement sensor, and limit sensor are all communicatively connected to the controller. The laser detection mechanism is used to scan whether there is a target device in the restricted area. The position sensor can detect the state of the door. The displacement sensor can detect the state of the sealing mechanism. The limit sensor is used to detect the state of the drive mechanism. The environmental chamber collision avoidance method includes: receiving a first detection signal sent by the position sensor; when the first detection signal is a door opening signal, controlling the drive mechanism to drive the sealing mechanism to switch to a first position and receiving the scanning signal sent by the laser detection mechanism in real time; determining whether there is a target device in the restricted area based on the scanning signal; if there is a target device in the restricted area, controlling the alarm device to sound an alarm.

[0016] Furthermore, the internal space is also pre-defined with a target area, and the laser detection mechanism is used to scan whether there is a target device in the target area. The environmental cabin collision avoidance method also includes: judging whether there is a target device in the target area based on the scanning signal; if there is a target device in the target area, controlling the cabin door to close the hatch.

[0017] Furthermore, after the control hatch closes the hatch, the environmental chamber collision avoidance method also includes: receiving a first detection signal sent by a position sensor; when the first detection signal is a door closing signal, controlling the drive mechanism to drive the sealing mechanism to switch to a second position.

[0018] The beneficial effects of this invention are: The environmental chamber anti-collision system and method proposed in this invention, by setting a sealing mechanism in the chamber that can open or close the opening of the through channel in the chamber wall, isolates the internal space of the environmental chamber from the detection device when the sealing mechanism closes the opening, thereby reducing the impact of the extreme temperature and humidity environment inside the chamber on the detection device, while the detection device can detect the target device when the opening is open, thus protecting the detection device from damage without affecting the monitoring of the target device's dynamics.

[0019] At the same time, the sealing mechanism can also seal the opening, ensuring that the interior of the cabin maintains an extreme temperature and humidity environment. Attached Figure Description

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0025] See Figures 1-3 This invention provides an environmental cabin collision avoidance system, including a cabin body 1, a sealing mechanism 2, and a detection device.

[0026] The cabin 1 includes a bulkhead 11, which encloses an internal space. The internal space has a pre-defined restricted area. A through passage 12 is provided on the bulkhead 11, and the through passage 12 is connected to the internal space at the opening position.

[0027] The sealing mechanism 2 is located at the opening and can switch between a first position with the opening open and a second position with the opening closed.

[0028] The detection device is installed in the through channel 12. When the sealing mechanism 2 is in the first position, the detection device is used to detect whether there is a target device in the restricted area.

[0029] It should be noted that the restricted area refers to a certain area located near the bulkhead 11, which is a pre-set area within the environmental cabin collision avoidance system because the target equipment may touch the bulkhead 11 when it moves into the above-mentioned area.

[0030] The environmental chamber collision avoidance system provided in this embodiment of the invention has a through channel 12 in the chamber wall 11, and a sealing mechanism 2 for opening or closing the opening is provided at the opening of the through channel 12. The movement of the sealing mechanism 2 realizes the communication or isolation between the detection device and the internal space of the chamber 1. When the sealing mechanism 2 is in the first position, that is, when the opening of the through channel 12 is open, the detection device can perform real-time detection on the target equipment in the environmental chamber. Without affecting the operation of the detection device, the sealing mechanism 2 can isolate this function, thereby preventing the extreme temperature and humidity conditions in the chamber 1 from affecting the detection device, reducing damage, and thus extending the service life and efficiency of electrical components. At the same time, the sealing mechanism 2 prevents gas leakage from the inside of the chamber 1, thereby ensuring that the inside of the chamber 1 maintains an extreme temperature and humidity environment.

[0031] In one embodiment, the through channel 12 can be configured as one or more, and the through channel 12 can be configured on any one or more bulkheads 11 of the cabin 1. By setting multiple detection devices in the corresponding through channel 12, it is possible to perform all-round detection on the target equipment inside the cabin 1.

[0032] In one embodiment, the sealing mechanism 2 can be a plate-shaped structure. When the flat outer wall of the plate-shaped structure comes into contact with and fits against the cabin wall 11 of the cabin 1, it can effectively seal the opening of the through channel 12.

[0033] In one embodiment, the sealing mechanism 2 includes a housing and an insulation layer. The housing has a hollow inner cavity, and the insulation layer is disposed in the hollow inner cavity for insulation purposes, preventing the temperature from being too cold or too hot and affecting the components outside the cabin 1.

[0034] In one embodiment, the insulation layer can be foamed cotton, fibrous cotton, etc., providing good thermal insulation performance.

[0035] In one embodiment, the inner wall of the sealing mechanism 2, i.e. the cavity wall of the hollow inner cavity, and the outer wall of the sealing mechanism 2 are both made of stainless steel to ensure that they will not be corroded under extreme temperature and humidity conditions.

[0036] In one embodiment, the environmental chamber collision avoidance system includes a hinge assembly 71, and the sealing mechanism 2 and the bulkhead 11 are connected by the hinge assembly 71 to rotatably mount the sealing mechanism 2 onto the bulkhead 11.

[0037] In one embodiment, the hinge assembly 71 can be made of stainless steel to reduce problems such as rusting of the hinge assembly 71 caused by high and low temperatures and high humidity gases inside the cabin 1.

[0038] In one embodiment, the environmental chamber collision avoidance system further includes a reinforcing plate 72, which is annular and surrounds the outer periphery of the opening. The reinforcing plate 72 is located between the hinge assembly 71 and the bulkhead 11. By providing the reinforcing plate 72, rigid support is provided for the connection between the hinge assembly 71 and the bulkhead 11, thus stabilizing the connection.

[0039] In one embodiment, the reinforcing plate 72 is made of stainless steel to prevent corrosion.

[0040] In one embodiment, the environmental chamber anti-collision system further includes a seal 73, which is disposed on the side of the sealing mechanism 2 near the through channel 12. When the sealing mechanism 2 is in the first position, the chamber wall 11 and the sealing mechanism 2 together clamp the seal 73 to prevent gas in the chamber 1 from leaking out from the through channel 12.

[0041] In one embodiment, the seal 73 can be a sealing strip. When the seal 73 is clamped between the sealing mechanism 2 and the reinforcing plate 72, the reinforcing plate 72 provides a planar area for pressing the sealing strip, thereby further improving the sealing effect.

[0042] In one embodiment, the environmental chamber anti-collision system further includes a heat insulation plate 74, which is arranged around the inner wall of the through channel 12 to further prevent the failure of electrical components such as detection devices.

[0043] In one embodiment, the environmental chamber collision avoidance system further includes a drive mechanism 3, which is connected to the sealing mechanism 2 and is used to drive the sealing mechanism 2 to switch between a first position and a second position.

[0044] In one embodiment, at least two sets of drive mechanisms 3 are provided, and the two sets of drive mechanisms 3 are arranged in parallel to ensure that the sealing mechanism 2 remains horizontal when it rotates, so as to avoid the sealing mechanism 2 not rotating into place and affecting the detection effect of the detection device.

[0045] For example, the driving mechanism 3 can be a combination of a cylinder structure, an electric cylinder structure, a motor and a lead screw, etc. The sealing mechanism 2 is driven to rotate by the extension and retraction of the cylinder, electric cylinder or lead screw, so as to drive the sealing mechanism 2 to open or close the opening. The structure is simple and easy to operate. All mechanisms that can realize the switching of the sealing mechanism 2 between the first position and the second position are within the protection scope of the embodiments of this disclosure. The embodiments of this disclosure will not be described in detail one by one.

[0046] In one embodiment, the environmental chamber anti-collision system further includes a fixed bracket 6, which is disposed outside the chamber 1 or in the through channel 12. The fixed bracket 6 is connected to the side of the drive mechanism 3 away from the sealing mechanism 2 and is used to support the movement of the drive mechanism 3.

[0047] In one embodiment, the drive mechanism 3 includes a main body 31 and a movable part 32 that can move linearly relative to it. The main body 31 of the drive mechanism 3 is rotatably connected to the fixed bracket 6, and the movable part 32 is rotatably connected to the sealing mechanism 2.

[0048] The drive mechanism 3 can have an extended position and a retracted position relative to the fixed bracket 6 under the support of the fixed bracket 6. When the sealing mechanism 2 is in the second position, the drive mechanism 3 is in the retracted position, and when the sealing mechanism 2 is in the first position, the drive mechanism 3 is in the extended position.

[0049] It should be noted that the extended position refers to the farthest front end of the movable part 32 of the drive mechanism 3 in the direction of movement, that is, the end of the movable part 32 of the drive mechanism 3 is farthest from the fixed bracket 6, and the retracted position refers to the movable part 32 of the drive mechanism 3 retracting to the last end, that is, the end of the movable part 32 of the drive mechanism 3 is closest to the fixed bracket 6.

[0050] For example, when the drive mechanism 3 adopts a cylinder structure, the cylinder structure includes a piston rod and a cylinder body, wherein the piston rod is the movable part 32 of the drive mechanism 3, the cylinder body is the main body 31 of the drive mechanism, one end of the piston rod is disposed in the cylinder body, and the piston rod can extend and retract relative to the cylinder body, the cylinder body is connected to the fixed bracket 6, and the other end of the piston rod is connected to the sealing mechanism 2. The extension and retraction of the piston rod drives the rotation of the sealing mechanism 2. When the end of the piston rod connected to the sealing mechanism 2 moves to the position furthest from the fixed bracket 6, it reaches the extended position. When the end of the piston rod connected to the sealing mechanism 2 moves to the position closest to the fixed bracket 6, it reaches the retracted position.

[0051] In one embodiment, the environmental chamber collision avoidance system further includes a mounting bracket 5, which is fixedly mounted on the sealing mechanism 2 on the side away from the chamber 1. The movable part 32 of the drive mechanism 3 is rotatably mounted on the mounting bracket 5. When the drive mechanism 3 moves, it needs to drive the sealing mechanism 2 to rotate, maintaining synchronization and balance with the movement of the sealing mechanism 2 relative to the chamber wall 11, in order to drive the sealing mechanism 2 to rotate to the first position.

[0052] For example, the mounting bracket 5 is provided with a connector 51, and the end of the movable part 32 of the drive mechanism 3 is provided with a socket, which is plugged into the socket to rotatably mount the drive mechanism 3 on the mounting bracket 5.

[0053] In one embodiment, the fixed bracket 6 can be made of steel to provide rigid support for the drive mechanism 3 and ensure that the drive mechanism 3 works stably.

[0054] In one embodiment, the bottom side of the fixed bracket 6 is connected to the drive mechanism 3, and the top of the fixed bracket 6 can be installed on the cabin 1 or other rigid structure for fixing, without specific limitation.

[0055] In one embodiment, the detection device includes a laser detection mechanism 4, an alarm device, and a controller.

[0056] The laser detection mechanism 4 is installed in the through channel 12. When the sealing mechanism 2 is in the first position, the laser detection mechanism 4 is used to scan the restricted area to check for the presence of target equipment. The laser detection mechanism 4 scans in a fan-shaped scanning state. When the laser detection mechanism 4 is installed in the through channel 12, it can achieve a full-range, blind-angle scan from point-to-point linear scanning to the entire scanning surface of the bulkhead 11, thereby ensuring that the entire wall surface of the corresponding bulkhead 11 is not subject to collision and improving the early warning effect.

[0057] The controller is communicatively connected to the drive mechanism 3 and the laser detection mechanism 4 respectively. The controller is configured to control the drive mechanism 3 to move to drive the sealing mechanism 2 to switch between the first position and the second position when the preset trigger conditions are met.

[0058] For example, the alarm device can be an LED light, a buzzer, etc. All devices that can provide an alert are within the protection scope of the embodiments of this disclosure, and will not be described in detail in the embodiments of this disclosure.

[0059] For example, the controller and the alarm device can communicate via data cable, UART serial communication, RS-bus communication, SPI bus communication (i.e., serial peripheral interface), wireless communication (such as Bluetooth, WiFi, ZigBee, etc.). All structures that can realize the communication connection between the controller and the alarm device are within the protection scope of this optional embodiment.

[0060] For example, the controller and the laser detection mechanism 4 can communicate via data cable, UART serial communication, RS-bus communication, SPI bus communication (i.e., serial peripheral interface), wireless communication (such as Bluetooth, WiFi, ZigBee, etc.). All structures that can realize the communication connection between the controller and the laser detection mechanism 4 are within the protection scope of this optional embodiment.

[0061] In one embodiment, the laser detection mechanism 4 can generate a detection surface that is parallel to the horizontal plane. This configuration enables the laser detection mechanism 4 to perform a large-scale scan, increasing the scanning coverage area and thus reducing the probability of the target device touching the bulkhead 11.

[0062] For example, the laser detection mechanism 4 can be disposed on the inner top wall of the through channel 12, with the detection surface parallel to the plane of the inner top wall of the through channel 12. The laser detection mechanism 4 can also be disposed on the inner bottom wall of the through channel 12, with the detection surface parallel to the plane of the inner bottom wall of the through channel 12.

[0063] In one embodiment, the through passage 12 can also be disposed on the bulkhead 11 at the top of the cabin 1, and the laser detection mechanism 4 can also be disposed in the through passage 12 on the bulkhead 11 at the top of the cabin 1 for scanning target equipment with high-altitude collision risk.

[0064] In one embodiment, the bulkhead 11 has a hatch that communicates with the internal space for the target equipment to enter and exit the environmental chamber.

[0065] In one embodiment, the environmental chamber collision avoidance system includes a hatch located at the hatch opening, which can be switched between an open hatch position and a closed hatch position.

[0066] In one embodiment, the environmental chamber collision avoidance system further includes a position sensor and / or a displacement sensor 8 and / or a limit sensor.

[0067] In one embodiment, the position sensor is communicatively connected to the controller, and the position sensor is able to detect the state of the hatch and send a first detection signal to the controller.

[0068] It should be noted that the first detection signal is either an open door signal or a close door signal. When the hatch is open, the first detection signal is an open door signal; when the hatch is closed, the first detection signal is a close door signal.

[0069] The controller can receive the first detection signal sent by the position sensor. When the first detection signal is an opening signal, the controller controls the drive mechanism 3 to move to drive the sealing mechanism 2 to rotate to the first position. At this time, the laser emitted by the laser detection mechanism 4 enters the internal space of the cabin 1 to perform scanning. The controller receives the scanning signal sent by the laser detection mechanism 4 in real time.

[0070] In one embodiment, a position sensor is installed at the hatch to detect the hatch's status in real time.

[0071] In this embodiment of the invention, the controller is configured to communicate with the position sensor, the drive mechanism 3, and the laser detection mechanism 4 respectively. When the hatch is opened, the target device enters the cabin 1. At this time, the first detection signal received by the controller is the door opening signal, indicating that the hatch is in the open hatch state. The controller will then control the drive mechanism 3 to move, thereby driving the sealing mechanism 2 to rotate. When the sealing mechanism 2 rotates to the first position to open the opening of the through channel 12, the laser detection mechanism 4 will scan the target device entering the cabin 1 and monitor the position of the target device in real time. This realizes the automated control of the environmental cabin anti-collision system and avoids the risk of damage to the cabin wall 11 or property loss caused by the need for manual observation and reminders or the setting of passive anti-collision structures.

[0072] For example, the position sensor in this disclosure embodiment can be a photoelectric sensor, a door magnetic sensor, a proximity switch, a limit switch, etc. All devices capable of detecting whether a hatch is open or closed are within the protection scope of this disclosure embodiment, and will not be described in detail in this disclosure embodiment.

[0073] In one embodiment, the displacement sensor 8 is disposed in the through channel 12 and is communicatively connected to the controller. The displacement sensor 8 can detect the state of the sealing mechanism 2 and send a second detection signal to the controller to determine whether the sealing mechanism 2 has closed the through channel 12, so as to ensure that the sealing mechanism 2 closes the through channel 12 to prevent the leakage of cold air or high temperature gas in the cabin 1, which could cause damage to the external components of the cabin 1.

[0074] The controller can determine whether the sealing mechanism 2 has reached the first position or the second position based on the received second detection signal, which facilitates the subsequent control operation of the drive mechanism 3 to ensure that the sealing mechanism 2 moves into position.

[0075] For example, the displacement sensor 8 in this embodiment of the disclosure can be a photoelectric sensor, a door magnetic sensor, a proximity switch, a limit switch, etc. All devices that can detect whether the sealing mechanism 2 is closed in place are within the protection scope of this embodiment of the disclosure, and will not be described in detail in this embodiment of the disclosure.

[0076] In one embodiment, the environmental chamber collision avoidance system further includes a limit sensor, which is communicatively connected to the controller and is located on the drive mechanism 3, enabling it to detect the state of the drive mechanism 3.

[0077] Specifically, limit sensors are disposed on the main body 31 and the movable part 32 of the drive mechanism 3, and displacement sensor 8 can detect the movement position of the movable part 32, that is, detect the extended position and retracted position of the drive mechanism 3. In this embodiment of the invention, displacement sensor 8 is set to detect the state of drive mechanism 3 and send a third detection signal to controller, so that controller can control the movement of drive mechanism 3 to ensure the angle of opening or closing of the through channel 12 of sealing mechanism 2, thereby ensuring the scanning detection effect of laser detection mechanism 4.

[0078] For example, the displacement sensor 8 in this embodiment of the disclosure can be a magnetic switch, etc. All devices that can detect the extended and retracted positions of the drive mechanism 3 are within the protection scope of this embodiment of the disclosure, and will not be described in detail in this embodiment of the disclosure.

[0079] It should be noted that the position sensor, displacement sensor 8, and limit sensor can all be set simultaneously or one of them can be selected.

[0080] See Figures 4-5 This invention also provides an environmental chamber collision avoidance method, applied to the environmental chamber collision avoidance system provided in the above embodiments, comprising: Step S110: Receive the first detection signal sent by the position sensor.

[0081] In step S110 above, the first detection signal is an open door signal or a close door signal. When the first detection signal is an open door signal, it indicates that the hatch is in the open hatch state. When the first detection signal is a close door signal, it indicates that the hatch is in the closed hatch state.

[0082] After step S110 above, that is, after receiving the first detection signal, it is necessary to determine whether the first detection signal is an open signal. If the first detection signal is not an open signal, continue to receive and determine the first detection signal. If the first detection signal is an open signal, execute the following step S120.

[0083] Step S120: When the first detection signal is the door opening signal, control the drive mechanism 3 to drive the sealing mechanism 2 to switch to the first position, and receive the scanning signal sent by the laser detection mechanism 4 in real time.

[0084] In step S120 above, when the first detection signal is the door opening signal, the target device enters the cabin 1. At this time, a control command is sent to the drive mechanism 3. After receiving the control command, the drive mechanism 3 moves to the extended position, thereby driving the sealing mechanism 2 to rotate to the first position, controlling the laser detection mechanism 4 to start working, scanning the target device in real time, and feeding back the scanning signal to the controller.

[0085] Step S130: Determine whether the target device exists in the restricted area based on the scanning signal.

[0086] In step S130 above, the restricted area is pre-configured within the controller. When the environmental cabin collision avoidance system is operating, the controller sends the information of the pre-configured restricted area to the laser detection mechanism 4 via wired or wireless means, guiding the laser detection mechanism 4 to perform scanning according to the pre-set information. The laser detection mechanism 4 scans according to the instructions sent by the controller and sends the original scan information (i.e., the target device location information) back to the controller. After receiving the scan information, the controller compares the actual target device location with the pre-configured restricted area to determine whether the target device has entered or exists within the restricted area.

[0087] Step S140: If no target device exists in the restricted area, continue receiving scanning signals.

[0088] Step S140: If the target device is present in the restricted area, the alarm device is activated.

[0089] This invention provides an active prevention mechanism by setting up the above-mentioned environmental chamber anti-collision method to achieve automated process detection of the target equipment after it enters the chamber 1, and to promptly remind the operator to stop work when the target equipment enters the restricted area, thus avoiding the occurrence of collisions with the target equipment.

[0090] In one embodiment, a target area is also pre-defined inside the cabin 1, and the laser detection mechanism 4 is also used to scan whether the target area contains a target device.

[0091] It should be noted that the target area refers to the spatial range of the target device designated for specific observation, testing, or operation.

[0092] The aforementioned environmental chamber collision avoidance methods also include: Step S210: Determine whether the target device exists in the target area based on the scanning signal.

[0093] In step S210 above, the target area is pre-configured in the controller. After receiving the scanning information, the actual target device location is compared with the preset target area to determine whether the target device has entered or exists in the target area.

[0094] Step S220: If no target device exists in the target area, continue receiving scanning signals.

[0095] Step S230: If the target equipment is present in the target area, control the hatch to close the hatch.

[0096] In one embodiment, the hatch is equipped with an electric button, which is communicatively connected to a controller and is used to receive opening and closing commands sent by the controller to switch between the states of opening and closing the hatch.

[0097] In step S230 above, the hatch can be closed manually by the operator or by sending a closing command to the electric button.

[0098] It should be noted that the execution of steps S130-S150 and steps S210-S230 is not restricted in any particular order; they can be executed simultaneously or in stages.

[0099] In one embodiment, after step S230, i.e. after the control hatch closes the hatch, the environmental chamber collision avoidance method further includes: Step S240: Receive the first detection signal sent by the position sensor.

[0100] After step S240 above, the received first detection signal needs to be judged to determine whether the first detection signal is a door closing signal. If the first detection signal is not a door closing signal, the first detection signal is received and judged again. If the first detection signal is a door closing signal, the following step S250 is executed.

[0101] Step S250: When the first detection signal is a door closing signal, control the drive mechanism 3 to move so as to drive the sealing mechanism 2 to switch to the second position.
