Its core requirement is to maintain a stable internal medical environment (such as temperature, humidity, and cleanliness) in a complex and ever-changing external environment, ensuring the normal operation of medical equipment and the smooth conduct of medical procedures.

[0003] Most existing medical mobile units have fixed structures, which cannot be flexibly adjusted according to equipment size and usage requirements, resulting in low space utilization. This phenomenon has become an urgent problem to be solved by people in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a medical mobile unit and its control system for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a medical mobile cabin and its control system, comprising a main cabin body and a mobile cabin control system. The main cabin body includes sliding grooves on both sides, and an extension section is slidably connected inside each of the two sets of sliding grooves. A drive mechanism is provided inside the main cabin body. The drive mechanism includes a hydraulic cylinder fixedly installed with the main cabin body. A first connecting block is connected to the output end of the hydraulic cylinder near the extension section. A second connecting block is fixedly connected to the side of the extension section near the first connecting block. A first slot matching the first connecting block is opened inside the second connecting block. A first cylinder is fixedly installed on the top of the second connecting block. The output end of the first cylinder extends to the first slot and connects to the top of the first connecting block. A displacement sensor is installed inside the main cabin body.

[0006] The present invention further illustrates that an air pump is installed inside the main cabin, an inflatable sealing ring is provided at the gap connection between the main cabin and the extension section, a second pressure sensor is provided outside the inflatable sealing ring, and the air inlet of the air pump is connected to the inflatable sealing ring through a pipe.

[0007] The present invention further illustrates that a support frame is fixedly installed on one side of the extended compartment, a motor is fixedly installed on one end of the support frame, the output end of the motor extends into the interior of the support frame and is connected to a lead screw, and one end of the lead screw is connected to the support frame through a bearing.

[0008] The present invention further illustrates that the lead screw is externally threaded with a threaded block, and the lead screw is also externally fitted with a support block that is fixedly connected to the support frame. The bottom of both the threaded block and the support block is hinged with a support rod, and the two sets of support rods are arranged crosswise.

[0009] The present invention further illustrates that the bottom of both sets of support rods is hinged to a base plate, and a first pressure sensor is provided at the bottom of the base plate.

[0010] The present invention further illustrates that a ventilation opening is provided on one side of the extended compartment, a filter device is provided inside the ventilation opening, a fan is installed on the side of the ventilation opening near the interior of the extended compartment, and a sealing door is hinged to the side of the ventilation opening on the outer surface of the extended compartment.

[0011] The present invention further illustrates that the filtration device includes a mounting frame slidably connected to the vent, two sets of filter screens are fixedly connected inside the mounting frame, and a wind speed sensor is fixedly installed inside the mounting frame.

[0012] The present invention further illustrates that the container control system includes a data acquisition module and a control module.

A displacement sensor monitors the displacement in real time and stops the machine once the target displacement is reached. Subsequently, an air pump inflates the sealing rings at the gaps, and a second pressure sensor monitors the air pressure and adaptively replenishes air to ensure a seal. After sealing, the motor-driven screw inside the support frame adjusts the cross support rods, ensuring the bottom plate touches the ground. A first pressure sensor monitors the pressure to ensure stable support. During ventilation, the sealed door opens, and the fan operates, allowing purified air to enter the cabin through a filter. A wind speed sensor monitors the filter blockage. The control system acquires sensor data through various acquisition submodules, and the corresponding control submodules regulate each component. In case of abnormalities, the early warning submodule alarms, ensuring the stable operation of the modular cabin. Attached Figure Description

[0018] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-11 The present invention provides a technical solution: a medical modular unit and its control system, comprising a main unit 1 and a modular unit control system. The main unit 1 includes sliding grooves 2 on both sides, and an extension section 3 is slidably connected inside both sets of sliding grooves 2. A drive mechanism 4 is provided inside the main unit 1. The drive mechanism 4 includes a hydraulic cylinder 5 fixedly installed with the main unit 1. A first connecting block 6 is connected to the output end of the hydraulic cylinder 5 near the extension section 3. A second connecting block 7 is fixedly connected to the side of the extension section 3 near the first connecting block 6. A first slot 8 matching the first connecting block 6 is opened inside the second connecting block 7. A first cylinder 9 is fixedly installed on the top of the second connecting block 7. The output end of the first cylinder 9 extends to the first slot 8 and connects to the top of the first connecting block 6. A displacement sensor 25 is installed inside the main unit 1.

[0020] In the initial state, the expansion section 3 is housed within the slide groove 2 of the main body 1, the hydraulic cylinder 5 is in the retracted state, the first connecting block 6 at the output end of the hydraulic cylinder 5 is embedded in the first slot 8 of the second connecting block 7 of the expansion section 3, and the first cylinder 9 is in the extended state, locking and limiting the first connecting block 6. When the container needs to expand its space, the hydraulic cylinder 5 is activated first. The output end of the hydraulic cylinder 5 pushes the first connecting block 6 to slide along the first slot 8, thereby causing the expansion section 3 to slide along the slide groove 2 towards the outside of the main body 1. The displacement sensor 25 installed inside the main body 1 collects the sliding distance of the expansion section 3 in real time. When the displacement distance reaches the required expansion value, the hydraulic cylinder... 5. When the container is no longer in use, the container control system controls the hydraulic cylinder 5 to retract in the reverse direction, pulling the first connecting block 6 to move in the reverse direction along the first slot 8, and driving the extended compartment 3 to slide along the slide 2 into the main body 1. The displacement sensor 25 monitors the retraction displacement distance of the extended compartment 3 in real time. When the displacement data reaches the preset retraction value, the hydraulic cylinder 5 stops retracting. If the first cylinder 9 retracts, the output end of the hydraulic cylinder 5 drives the first connecting block 6 away from the first slot 8 at the second connecting block 7, which allows the extended compartment 3 to be disassembled, maintained, or replaced separately in the later stage. At the same time, when the hydraulic cylinder 5 malfunctions, the extended compartment 3 can be manually pushed to unfold or retract.

[0021] It should be noted that the displacement sensor 25 is used to monitor the displacement distance of the extension section 3 in real time when it is retracted or extended.

[0022] An air pump 10 is installed inside the main body 1. An inflatable sealing ring 11 is installed at the gap between the main body 1 and the extension section 3. A second pressure sensor 26 is installed on the outside of the inflatable sealing ring 11. The air inlet of the air pump 10 is connected to the inflatable sealing ring 11 through a pipe.

[0023] After the extended section 3 is deployed, the control system controls the air pump 10 to start. The air pump 10's air outlet inputs airflow through the pipe into the interior of the inflatable sealing ring 11, which can inflate the inflatable sealing ring 11 and maintain the sealing state.

[0024] It should be further explained that the inflatable sealing ring 11, also known as an airbag, is a hollow flexible sealing device made of materials such as silicone rubber and EPDM rubber. It is equipped with an inflation / deflation nozzle. It achieves sealing contact by inflating and expanding, and elastically retracts away from the interface after deflation. It is used to seal gaps. This is existing technology. The second pressure sensor 26 continuously monitors the air pressure of the inflatable sealing ring 11. If the air pressure drops, such as if the inflatable sealing ring 11 leaks, the control system automatically starts the air pump 10 to replenish air and maintain the sealing state.

[0025] A support frame 12 is fixedly installed on one side of the extended compartment 3. A motor 13 is fixedly installed on one end of the support frame 12. The output end of the motor 13 extends into the interior of the support frame 12 and is connected to a lead screw 14. One end of the lead screw 14 is connected to the support frame 12 through a bearing.

[0026] The lead screw 14 is externally threaded with a threaded block 15. The lead screw 14 is also externally fitted with a support block 16 that is fixedly connected to the support frame 12. The bottom of the threaded block 15 and the support block 16 are both hinged with support rods 17. The two sets of support rods 17 are arranged crosswise. The bottom of the two sets of support rods 17 is hinged with a base plate 18. The bottom of the base plate 18 is provided with a first pressure sensor 19.

[0027] After sealing is completed, the control system starts the motor 13 on the support frame 12 on one side of the extended compartment 3. The output end of the motor 13 drives the lead screw 14 to rotate. At the same time, the threaded block 15 moves along the axial direction of the lead screw 14. The two sets of cross support rods 17, which are hinged to the bottom of the threaded block 15 and the support block 16, change angle with the movement of the threaded block 15, pushing the bottom plate 18 to move downward until it contacts the ground. The first pressure sensor 19 at the bottom of the bottom plate 18 collects the ground reaction force in real time. When the pressure value reaches the preset ground contact threshold, it indicates that the bottom plate 18 has reliably contacted the ground. The control system immediately stops the operation of the motor 13. The cross support rods 17 maintain the current angle to provide stable bottom support for the extended compartment 3.

[0028] It should be added that the first pressure sensor 19 continuously monitors the pressure of the supporting base plate 18. If the pressure value drops suddenly, such as when the ground collapses and the base plate 18 is suspended, the control system starts the motor 13 and adjusts the length of the cross support rod 17 so that the base plate 18 re-contacts the ground and reaches the preset pressure value.

[0029] A vent 20 is provided on one side of the extended section 3. A filter device 21 is installed inside the vent 20. A fan 22 is installed on the side of the vent 20 near the interior of the extended section 3. A sealing door 23 is hinged to the side of the vent 20 on the outer surface of the extended section 3.

[0030] The filter device 21 includes a mounting frame 2101 that is slidably connected to the vent 20. Two sets of filter screens 2102 are fixedly connected inside the mounting frame 2101, and a wind speed sensor 24 is fixedly installed inside the mounting frame 2101.

[0031] The control system controls the hinged opening of the sealing door 23 on the outer surface of the vent 20 of the extended compartment 3, so that the vent 20 is connected to the outside. The control system starts the fan 22 inside the vent 20. The fan 22 generates negative pressure, allowing outside air to enter the compartment through the vent 20. When the air flows through the filter device 21, it first passes through the two sets of filter screens 2102 in the mounting frame 2101 to filter impurities in the air, thereby purifying the air. The wind speed sensor 24 installed inside the mounting frame 2101 monitors the wind speed in real time after the two sets of filter screens 2102 have filtered out the impurities in the air. When the wind speed is lower than the preset threshold, it indicates that too many impurities have accumulated on the surface of the filter screens 2102, and the resistance has increased.

[0032] The wind speed sensor 24 monitors the wind speed in real time after the two sets of filters 2102 have filtered out impurities in the air. When the wind speed is lower than the preset threshold, it indicates that too many impurities have accumulated on the surface of the filter 2102.

[0033] The control system of the mobile cabin includes a data acquisition module and a control module. The data acquisition module includes a displacement acquisition submodule, a pressure acquisition submodule one, a pressure acquisition submodule two, and a differential pressure acquisition submodule. The displacement acquisition submodule is electrically connected to the displacement sensor 25, the pressure acquisition submodule one is electrically connected to the first pressure sensor 19, the pressure acquisition submodule two is electrically connected to the second pressure sensor 26, and the differential pressure acquisition submodule is electrically connected to the wind speed sensor 24.

[0034] The control module includes a drive control submodule, a sealing control submodule, a support adjustment submodule, a ventilation control submodule, and an early warning submodule.

[0035] The drive control submodule is electrically connected to the hydraulic cylinder 5 and the first cylinder 9; the sealing control submodule is electrically connected to the air pump 10; the support adjustment submodule is electrically connected to the motor 13; the ventilation control submodule is electrically connected to the fan 22; and the early warning submodule is electrically connected to the first pressure sensor 19, the wind speed sensor 24, the displacement sensor 25, and the second pressure sensor 26.

[0036] The medical mobile cabin control system includes the following operating methods: Method 1: When the modular cabin needs to be used, the drive mechanism 4 controls the expansion section 3 to be deployed, thereby expanding the usable space of the main cabin 1. Method 2: During the use of the mobile medical unit, monitor the status of each module in the control module in real time to ensure the stability of the mobile medical unit's use; Method 2 includes the following specific steps: Method 2-a: Set the displacement distance of the extended section 3 and monitor the positioning status of the extended section 3; Specifically, the drive control submodule controls the hydraulic cylinder 5 to start and collects the displacement data of the extended compartment 3 in real time through the displacement sensor 25, which is then transmitted to the displacement acquisition submodule to confirm the position status of the extended compartment 3. If the extended compartment 3 is detected to have shifted, a signal is immediately transmitted to the early warning submodule to trigger an audible and visual alarm. At the same time, the drive control submodule controls the first cylinder 9 to lock it a second time. If the extended compartment 3 shifts, the hydraulic cylinder 5 needs to be controlled to fine-tune and reset to ensure that the extended compartment 3 is accurately positioned.

[0037] Method 2-b: Set a predetermined threshold for the first pressure sensor 19 and adjust its support height.

[0038] Specifically, after the extended section 3 is deployed, the support adjustment submodule controls the motor 13 to start. The output of the motor 13 drives the lead screw 14 to rotate in the forward direction. At the same time, the threaded block 15 moves along the axial direction of the lead screw 14. The two sets of cross support rods 17, which are hinged to the bottom of the threaded block 15 and the support block 16, change angle as the threaded block 15 moves, pushing the bottom plate 18 downward until it contacts the ground. The pressure acquisition submodule receives the support pressure data from the first pressure sensor 19 at the bottom of the bottom plate 18 in real time. When the pressure value is detected to be lower than the preset support threshold or drops sharply, the support adjustment submodule immediately starts the motor 13, causing the lead screw 14 to continue to rotate in the forward direction, adjusting the angle of the cross support rods 17, and pushing the bottom plate 18 to contact the ground until the first pressure sensor 19 detects that the pressure value has returned to the preset threshold. The motor 13 then stops running, ensuring the stability of the extended section 3 support. If the pressure still cannot meet the standard after adjustment, the warning submodule triggers an alarm, prompting the operators to check whether there is a fault in the ground or the support structure.

[0039] Furthermore, if the displacement sensor detects that the extended compartment 3 has shifted, and the actual support pressure data of the first pressure sensor 19 is lower than the preset support threshold, it is determined that the base plate 18 at the support adjustment submodule is not actually in contact with the ground, and the support for the extended compartment 3 is inadequate, causing the extended compartment 3 to shift. At this time, the driving force of the motor 13 should be increased simultaneously to quickly increase the support pressure to the threshold, thereby providing stable support for the extended compartment 3.

[0040] Furthermore, if the displacement sensor 25 detects that the displacement distance of the extended compartment 3 has not changed and is in a stuck state, but the actual support pressure data of the first pressure sensor 19 meets the preset support threshold, then it is determined that the hydraulic cylinder 5 is stuck and needs to be retracted in the reverse direction. If the displacement distance changes, the hydraulic cylinder 5 is restarted to extend in the forward direction. If the displacement distance does not change, it indicates that the hydraulic cylinder 5 is damaged and needs to be repaired.

[0041] Method 2-c: Set the sealing preset threshold of the second pressure sensor 26 and perform adaptive air replenishment.

[0042] Specifically, after the extended section 3 is deployed and stably supported, the sealing control submodule controls the air pump 10 to start, which can inflate the inflatable sealing ring 11 to maintain the sealing state. The pressure acquisition submodule continuously receives the air pressure data from the second pressure sensor 26. When the air pressure of the inflatable sealing ring 11 is detected to be lower than the preset sealing threshold, the sealing control submodule automatically starts the air pump 10 to replenish the air pressure of the inflatable sealing ring 11. During the replenishment process, the air pressure change needs to be monitored in real time. When the air pressure recovers to the threshold and stabilizes, the air pump 10 stops running. If the air pressure still cannot be maintained after multiple replenishments, the warning submodule triggers an alarm to prompt the operator to repair the inflatable sealing ring 11.

[0043] Method 2-d: Set the preset threshold for wind speed of wind speed sensor 24 to detect the clogging status of filter 2102.

[0044] Specifically, the differential pressure acquisition submodule can receive wind speed monitoring data from the wind speed sensor 24 in real time, analyze whether the two sets of filters 2102 are blocked, and when the wind speed is lower than the preset threshold, it indicates that too many impurities have accumulated on the surface of the filter 2102, and the resistance has increased. The warning submodule triggers an audible and visual alarm to prompt the operator to replace the filter 2102. At the same time, the ventilation control submodule automatically increases the speed of the fan 22 to temporarily improve the ventilation efficiency and avoid poor air circulation in the cabin. After the filter 2102 is replaced, the differential pressure returns to normal, and the speed of the fan 22 automatically returns to the preset value.

[0045] Furthermore, after the extended section 3 is deployed and stably supported, when the extended section 3 is in use, the first pressure sensor 19 adds additional support force. This additional support force and the early warning submodule form a graded alarm mode. Level 1 is when the additional support force exceeds the preset support threshold but does not reach the support upper limit. Level 2 is when the additional support force exceeds twice the preset support threshold and reaches the support upper limit.

[0046] If the additional support force reaches level one, and the second pressure sensor 26 detects that the air pressure of the inflatable sealing ring 11 is slowly decreasing and its air pressure is lower than the preset threshold, it is determined to be additional support force, which causes slight deformation of the cabin, and the inflatable sealing ring 11 is compressed, resulting in a change in air pressure. At this time, the sealing control submodule starts the air pump 10 in advance to replenish air and avoid insufficient sealing pressure in the future.

[0047] If the additional support force reaches level two, and the second pressure sensor 26 detects a sudden drop in the inflation seal ring 11, it indicates that the extended compartment 3 has undergone significant structural deformation due to overload, causing the inflation seal ring 11 to be squeezed and damaged. At this time, the load inside the compartment should be unloaded immediately, and the support adjustment submodule should immediately control the motor 13 to rotate in the opposite direction, driving the cross support rod 17 to retract slightly, reducing the support force of the first pressure sensor 19 to the level one threshold range, to prevent the support structure from breaking due to overload. At the same time, the first cylinder 9 is controlled to lock the current position of the extended compartment 3 in an emergency secondary tightening, preventing further displacement and deformation of the compartment. The warning submodule displays clear fault handling instructions on the operation panel, prompting maintenance personnel not to continue using the extended compartment 3, and to wait until the structure is repaired, the seals are replaced and tested as qualified before it can be reused.

[0048] If the additional support force of the extended compartment 3 reaches level two during use, but cannot be interrupted, it can be replaced immediately. The support adjustment submodule controls the starter motor 13 to make the drive screw 14 continue to rotate in the forward direction, adjusts the angle of the cross support rod 17, pushes the base plate 18 to contact the ground, pushes the extended compartment 3 upward, reduces the depression in the middle of the compartment, and the first cylinder 9 maintains the maximum torque locking state, applying pre-tightening force to the splice between the extended compartment 3 and the main compartment. At the same time, the damaged inflatable sealing ring 11 is replaced, and the inflatable sealing ring 11 is inflated by the air pump 10, and the inflation pressure is increased. Its elastic expansion characteristics are used to temporarily seal the damaged gap, preventing the leakage of clean air in the compartment or the entry of external pollutants. The inflatable sealing ring 11 under high pressure can form a slight pre-tightening force at the splice of the compartment, which helps to enhance the structural stability of the extended compartment 3 and prevents the damage from expanding further.
