Description

Technical Field

[0001] The present invention relates to the technical field of static balance monitoring and alarm devices, and specifically to a static settlement monitoring and alarm mechanism and an Internet of Things-enabled radiation-proof lead door. The static settlement monitoring and alarm mechanism can be installed in the radiation-proof lead door, and can monitor the settlement state of the lead plate in the radiation-proof lead door in real time, and can achieve the alarm purpose of sending an alarm signal when the settlement value of the lead plate reaches a warning threshold. Background Art

[0002] Radiation-proof lead door (also known as lead plate radiation-proof door) is mainly composed of materials such as lead and steel. Lead is a heavy metal element with good protective properties, which can effectively absorb and weaken electromagnetic waves and radioactive rays. Steel is the skeleton of the radiation-proof lead door, which has high strength and durability, and can ensure that the door is not easily deformed or damaged during use.

[0003] Radiation-proof lead doors are widely used in hospitals, laboratories, nuclear power facilities and other fields. In hospitals, radiation-proof lead doors can effectively protect against electromagnetic waves and radioactive rays generated by medical equipment, and protect the health of medical staff and patients. In laboratories, radiation-proof lead doors can protect against radioactive rays generated by experimental equipment, and protect the health and safety of experimental personnel. In nuclear power facilities, radiation-proof lead doors can protect against radioactive rays generated by nuclear reactors and related facilities, and protect the lives of workers.

[0004] The manufacturing process of radiation-proof lead door mainly includes the processing of lead plate and the welding of steel frame. The processing of lead plate has strict requirements, and the accuracy of thickness and size must be ensured, and the surface must be flat and flawless. The welding of steel frame requires exquisite craftsmanship to ensure the stability and strength of the frame. Finally, the lead plate and steel frame are assembled together to form a complete radiation-proof lead door. Figure 1 , Figure 2 As shown, the steel skeleton includes a steel plate 200 and a frame 300, and the lead plate 100 is fixed between the steel plate 200 and the frame 300 so as to be kept in a flat state.

[0005] Because lead metal has a high density, soft texture, high strength and hardness, after being fixed on the steel frame and installed in the protective door, the door body will be constantly subjected to vibration as the radiation-proof lead door is repeatedly opened and closed, so it is easy for the lead plate to statically settle relative to the steel frame. The lead plate is supported by the steel frame and its settlement speed is relatively slow, and the settlement speed is also related to many factors such as the frequency of opening and closing the door and the installation status. Generally speaking, when the settlement value of the lead plate is small, it will not affect the normal protection function of the radiation-proof lead plate door. However, when the settlement value of the lead plate is relatively large, the radiation will diffract from the gap between the lead plate and the door frame, posing a risk of harming human health and life safety. Because the lead plate is fixed inside the radiation-proof lead plate door, the settlement value / settlement status of the lead plate cannot be seen. Disassembling the door body to check the settlement status is not only labor-intensive and time-consuming, but also easy to damage the lead plate door. Therefore, it is urgent to design a mechanism that can monitor the settlement state of the lead plate in the radiation-proof lead door, so that when the settlement value of the lead plate is close to the risk position, an alarm signal can be issued in advance and timely intervention can be made to better ensure the life, health and safety of staff and patients. Summary of the invention

[0006] To achieve the above-mentioned objectives, the present invention provides a static settlement monitoring and alarm mechanism and an Internet of Things-enabled radiation-proof lead door, which can realize real-time supervision of the settlement status of the lead plate in the radiation-proof lead door, help to realize timely and effective supervision of the settlement of the lead plate, and can promptly issue an alarm when the settlement value of the lead plate is close to the risk position, promptly reminding maintenance personnel to intervene, which helps to better prevent damage to human life, health and safety that may be caused by lead plate settlement.

[0007] In order to achieve the technical purpose of the present invention, the technical scheme adopted is specifically as follows.

[0008] A static settlement monitoring and alarm mechanism comprises an arm plate, a U-shaped piece, a roller part and a strain sensing part.

[0009] The end plates of the U-shaped member are provided with studs, which can fix the U-shaped member on the vertical surface of the arm plate.

[0010] Elastic parts are formed on both arms of the U-shaped part, and the elastic parts can make the arms deform elastically, so that the free ends of the arms can have reciprocating travel space along the length direction of the arms.

[0011] The roller part includes a roller and a roller shaft. The roller is mounted on the roller shaft and can rotate relative to the roller shaft. The two ends of the roller shaft are fixedly matched with the two arms of the U-shaped member, so that the roller shaft cannot rotate relative to the U-shaped member. The roller surface on the side of the roller that is away from the end plate of the U-shaped member extends to the outside of the free end surface of the arm.

[0012] One end of the strain sensing part is fixedly connected to the roller surface of the rotating roller, and the other end is fixedly connected to the vertical surface of the arm plate.

[0013] When the rotating roller rotates relative to the roller shaft, the strain sensing part can be prompted to send a strain sensing signal.

[0014] Optionally, a groove is formed on the top of the rotating roller.

[0015] A first connection portion is disposed at one end of the base of the strain sensing portion, and a second connection portion is disposed at the other end.

[0016] Two axle protrusions are formed on the first connection part and the axle protrusions are matched with the side walls of the groove to connect one end of the base to the rotating roller.

[0017] The second connecting part is fixedly connected with a strip plate, a through hole is formed in the middle of the plate surface of the strip plate and a stud is arranged on the through hole, and the strip plate is fixed on the arm plate so that the other end of the base is fixedly connected with the arm plate.

[0018] Preferably, a cavity is formed in the middle of the opposite surface of the second connecting part and the strip plate, and the cap body of the stud matched on the strip plate is in the cavity, and the length of the stud screwed into the arm plate can be adjusted by screwing the cap body, thereby achieving the purpose of regulating the initial state of the strain sensing part.

[0019] Optionally, a groove is formed on the inner wall of the rotating roller, a strip-shaped through hole extending in the axial direction is formed at one end of the groove, and notches extending in the axial direction are formed at the other end of the groove and at the axial edge.

[0020] The axial middle of the roller is the center section, the axial ends of the center section are both middle sections, and the free ends of the middle section are both provided with prism sections. The inner diameter of the rotating roller is consistent with the outer diameter of the center section, and the outer diameter of the center section is larger than the outer diameter of the middle section.

[0021] The prism section matches the arm of the U-shaped piece. After the rotating roller is sleeved on the roller shaft, the strip-shaped through hole at least corresponds to the middle section and the two notches can correspond to the two middle sections respectively.

[0022] A connecting block is fixedly provided on each of the middle sections. A protruding arm is formed on the connecting block and extends radially along the roller shaft to the outside of the slot. A spacing extending in the circumferential direction is formed between the opposite surfaces of the protruding arm and the slot. A groove is formed at the free end of the protruding arm.

[0023] A hook body is arranged at one end of the strain sensing part, and a pull rod part is arranged at the other end. Nuts are arranged on two pull rods of the pull rod part.

[0024] The hook body matches the strip-shaped through hole on the rotating roller, so that one end of the strain sensing part is connected to the rotating roller.

[0025] The two pull rods of the pull rod part are matched with the two protruding arms and the middle of the pull rod is stuck in the groove. Screwing the nut arranged at the end of the pull rod can cause the pull rod to move relative to the groove to achieve the purpose of regulating the initial state of the strain sensing part. Obviously, the outer diameter of the nut is greater than the width of the groove.

[0026] In the above scheme, one end of the strain sensing part is connected to the roller to become the movable end, and the other end is connected to the roller shaft to become the fixed end. When the lead plate sinks and drives the roller to rotate relative to the roller shaft, the strain sensing part will be stretched and send out a sensing signal.

[0027] Optionally, a processor is also included. The processor includes a communication module, which can establish a communication connection with an external monitoring system, and the external monitoring system includes an alarm.

[0028] When the roller rotates relative to the roller shaft, the strain sensing signal emitted by the strain sensing part can be fed back to the processor, which analyzes and processes it and then sends a corresponding command signal to the external monitoring system. After receiving the alarm command, the alarm can send an alarm prompt including sound or light. The alarm command is only one type of command signal sent by the processor to the external monitoring system.

[0029] Optionally, the external monitoring system includes a scrolling screen. After the processor analyzes and processes the strain sensing signal, it can calculate the corresponding settlement value, and transmit it to the monitoring system in the form of a command signal and display it on the scrolling screen.

[0030] The monitoring system can be connected to multiple static settlement monitoring and alarming mechanisms, and can display multiple corresponding settlement values ​​in a loop on the scrolling screen. When the processor analyzes that a settlement value reaches the warning threshold, the corresponding settlement value number will change color and / or flash on the scrolling screen.

[0031] An alarm light may also be provided corresponding to each row of settlement values ​​on the scrolling screen. When a row of settlement values ​​on the scrolling screen exceeds the warning threshold, the alarm light corresponding to the row will sound an alarm and / or flash, so that the static settlement monitoring alarm mechanism that issued the alarm can be quickly found.

[0032] The external monitoring system can be a remote monitoring system connected through the Internet of Things communication network management.

[0033] An Internet of Things-enabled radiation-proof lead plate door comprises a lead plate fixed on a steel frame and at least one static settlement monitoring and alarm mechanism as mentioned above. The steel frame comprises a frame formed by cross-connecting a plurality of columns and a plurality of cross bars.

[0034] The arm plate is fixed on a cross bar located at the upper part of the frame and extends downward in a vertical direction. The surface of the arm plate facing the lead plate is a vertical surface.

[0035] After the U-shaped piece is fixed on the arm plate, the elastic part can undergo elastic deformation to press the roller surface of the rotating roller onto the plate surface of the lead plate.

[0036] Optionally, the static settlement monitoring alarm mechanism is connected to a processor, which includes a communication module and can establish a communication connection with a monitoring system, and the monitoring system includes an alarm.

[0037] When the lead plate settles, it can drive the roller to rotate relative to the roller shaft, causing the strain sensing part to send out a strain sensing signal. After the strain sensing signal is analyzed and processed by the processor, the processor will send out a command signal to the monitoring system. After receiving the alarm command signal, the alarm can send out an alarm prompt.

[0038] Optionally, the monitoring system includes a scrolling screen. After the processor analyzes and processes the strain sensing signal, it can calculate the settlement value of the corresponding lead plate, and transmit it to the monitoring system in the form of a command signal and display it on the scrolling screen.

[0039] The monitoring system can be connected to multiple radiation-proof lead doors equipped with the static settlement monitoring alarm mechanism, and can display multiple corresponding settlement values ​​cyclically through a scrolling screen. When the processor analyzes that a settlement value reaches a (preset) warning threshold, the corresponding settlement value number will change color and / or flash on the scrolling screen.

[0040] Optionally, each row of sedimentation values ​​on the scrolling screen is provided with an alarm light. When a row of sedimentation values ​​on the scrolling screen exceeds the early warning threshold, the alarm light corresponding to the row emits a sound and / or flash alarm signal.

[0041] The beneficial effects of the present invention are as follows: the static settlement monitoring and alarm mechanism and the Internet of Things-enabled radiation-proof lead door provided by the present invention can realize real-time monitoring of the settlement status of the lead plate in the radiation-proof lead door, which helps to achieve effective supervision of the settlement status of the lead plate, and can promptly issue an alarm when the settlement value of the lead plate is close to the risk position (i.e., reaches the warning threshold), promptly reminding maintenance personnel to intervene, and better preventing damage to human life, health and safety that may be caused by lead plate settlement.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0056] like Figures 1 to 11 The static settlement monitoring alarm mechanism shown in the figure comprises an arm plate 10, a U-shaped member 20, a roller portion 30 and a strain sensing portion 40. At least one side surface of the arm plate 10 is formed as a vertical surface distributed in the vertical direction.

[0057] The end plate 21 of the U-shaped member 20 is provided with a first stud 24, through which the U-shaped member 20 can be fixed on the vertical surface of the arm plate 10. The two arms 22 of the U-shaped member 20 are each formed with an elastic portion 23, and the elastic portion 23 can be elastically deformed along the length direction of the arm 22 (the extending direction along the X axis in the figure), so that the arm 22 can exert an elastic force along the length direction of the arm 22 on the roller shaft 34 (to be mentioned in the next paragraph).

[0058] The roller portion 30 includes a roller 31 and a roller shaft 34. The roller 31 is mounted on the roller shaft 34 and can rotate relative to the roller shaft 34. The two ends of the roller shaft 34 are respectively fixedly matched with the two arms 22 of the U-shaped member 20, so that the roller shaft 34 cannot rotate relative to the U-shaped member 20. The roller surface of the roller 31 on one side away from the end plate 21 of the U-shaped member 20 extends to the outside of the free end surface of the arm 22, that is, at Figure 1 , Figure 2 , Figure 6 In the embodiment, the left roller surface of the rotating roller 31 extends outward from the left end surface of the arm portion 22 .

[0059] A rubber layer 33 may be fixedly provided on at least one side of the roller surface of the rotating roller 31 away from the end plate 21 of the U-shaped member 20, so as to increase the contact between the roller surface at that side and the lead plate 100 (see Figure 1 , Figure 2 ) to enhance the transmission effect between the roller 31 and the lead plate 100, that is, the transmission capacity that can occur during the static friction sedimentation process.

[0060] One end of the strain sensing portion 40 is fixedly connected to the roller surface of the rotating roller 31 , and the other end is fixedly connected to the vertical surface of the arm plate 10 .

[0061] When the roller 31 rotates relative to the roller shaft 34 , the strain sensing unit 40 can be prompted to generate / send a strain sensing signal.

[0062] Embodiment 1: Figures 1 to 6 As shown, a groove 32 is formed on the top of the roller 31. The base 41 of the strain sensor 40 has a first connection portion 43 at the left end and a second connection portion 44 at the right end. The strain element is covered on the base 41 and covered inside with a cover plate 42. The lead wires of the strain sensor 40 are connected to the external processor 50 (see Fig.12 )connect.

[0063] Two axle protrusions are formed on the first connection portion 43 and are matched with the front and rear side walls of the groove 32 , so that the left end of the base 41 is fixedly connected to the rotating roller 31 .

[0064] The second connecting portion 44 is fixedly connected with a strip plate 45. A through hole is formed in the middle of the plate surface of the strip plate 45 and a second stud 46 is arranged on the through hole, and the strip plate 45 is fixed to the arm plate 10, so that the other end of the base 41 is fixedly connected with the arm plate 10.

[0065] A cavity 47 is formed in the middle of the opposite surfaces of the second connecting portion 44 and the strip plate 45, and the cap body 461 of the second stud 46 matched on the strip plate 45 is located in the cavity 47. The length of the second stud 46 screwed into the arm plate 10 can be adjusted by screwing the cap body 461, thereby achieving the purpose of adjusting the initial state of the strain sensing portion 40.

[0066] Embodiment 2: Figures 7 to 11 As shown, the roller portion 30 includes a roller 31 and a roller shaft 34. A recessed groove 311 is formed on the inner wall of the roller 31. The recessed groove 311 extends along the inner circumference of the roller 31 and penetrates to both ends of the roller 31 in the axial direction.

[0067] Assume that the roller 31 is rotated counterclockwise relative to the roller shaft 34 and Fig.11 As shown, when the sink 311 is rotated to the upper right position, a strip-shaped through hole 312 extending along the axial direction of the roller 31 is formed at the upper end of the sink 311 and corresponding to the middle position in the axial direction. Notches 313 extending along the axial direction of the roller 31 are respectively formed at the lower end of the sink 311 and corresponding to the edge position in the axial direction.

[0068] The axial middle of the roller shaft 34 is a center section 341, and both axial ends of the center section 341 are middle sections 342, and the free ends of the middle sections 342 are provided with prism sections 343. The inner diameter of the roller 31 is consistent with the outer diameter of the center section 341, and the outer diameter of the center section 341 is greater than the outer diameter of the middle section 342. In this way, after the roller 31 is mounted on the roller shaft 34, a radial spacing is formed between the inner circumference of the roller 31 and the outer circumference of the middle section 342.

[0069] The prism section 343 matches the arm portion 22 of the U-shaped member 20, so that the roller shaft 34 cannot rotate relative to the U-shaped member 20. After the roller portion 30 is installed on the U-shaped member 20, the strip-shaped through hole 312 is placed at the top of the roller 31 as much as possible, and the notch 313 is distributed on the side in the opposite direction (i.e., clockwise direction) to the direction in which the roller 31 rotates relative to the roller shaft 34 (counterclockwise direction in the figure).

[0070] After the rotating roller 31 is mounted on the roller shaft 34 , the strip-shaped through hole 312 at least corresponds to the middle section 341 and the two notches 313 can correspond to the two middle sections 342 respectively.

[0071] A connection block 35 is fixedly provided on each of the middle sections 342. The connection block 35 comprises an arc-shaped bottom plate 351 and a protruding arm 352 fixed at the middle of the plate surface of the bottom plate 351. A groove 353 is formed on the free end surface of the protruding arm 352.

[0072] The bottom plate 351 is fixed to the outer wall of the middle section 342 by screws. The protruding arm 352 extends along the radial direction of the roller shaft 34 / middle section 342 and the free end of the protruding arm 352 extends to the outside of the slot 313. A gap is formed between the protruding arm 352 and the opposite surface of the slot 313 in the circumferential direction (counterclockwise direction), see Fig.11 The groove 353 formed at the free end of the protruding arm 352 has a depth direction along the radial direction of the middle section 342 .

[0073] A hook body 48 is disposed at one end of the base 41 of the strain sensor 40, and a pull rod 49 is disposed at the other end. Nuts 492 are disposed on two pull rods 491 of the pull rod 49.

[0074] The hook body 48 matches with the strip-shaped through hole 312 on the roller 31, so that one end of the strain sensor 40 is connected to the roller 31. In order to facilitate the hook body 48 to be hooked on the strip-shaped through hole 312, the width of the strip-shaped through hole 312 around the circumference is made larger than the width of the hook body 48, so that the hook body 48 can be easily inserted into the strip-shaped through hole 312, so that the hook part of the hook body 48 matches and connects with one side edge of the strip-shaped through hole 312, see Fig.11 .

[0075] The two pull rods 491 of the pull rod part 49 are matched with the two protruding arms 352 and the pull rods 491 are inserted into the groove 353 from the radial port of the groove 353. The middle part of the pull rod 491 is stuck in the groove 353, and the end of the pull rod 491 extends out of the groove 353 and the end of the pull rod 491 is located on the side opposite to the end of the connecting base 41 on the pull rod part 49. The outer diameter of the nut 492 is greater than the width of the groove 353. Screwing the nut 492 disposed at the end of the pull rod 491 can cause the pull rod 491 to move relative to the groove 353, thereby realizing the regulation of the initial state of the strain sensor part 40. Moreover, screwing the nut 492 can pull the base 41 to stick to the outer peripheral surface of the roller 31, and at the same time cause the hook body 48 disposed at one end of the base 41 to establish a fixed connection relationship with the strip-shaped through hole 312.

[0076] One end of the strain sensing part 40 in the second embodiment is connected to the roller 31 to become a movable end; at the same time, the other end of the strain sensing part 40 is connected to the roller shaft 34 (the middle section 342 on it) to become a fixed end. When the lead plate 100 sinks and drives the roller 31 to rotate relative to the roller shaft 34, the strain sensing part 40 will be stretched and send out / generate a sensing signal, which is a real-time changing signal and has no regularity in the change.

[0077] Compared with the first embodiment, the second embodiment makes the strain sensing part 40 almost stick to the outer wall / outer circumference of the roller 31 instead of being in a suspended state, which can avoid the significant adverse effect of gravity or vibration generated in the vertical direction on the strain signal; in addition, with the help of the gap in the circumferential direction formed between the protruding arm 352 and the opposite surface of the notch 313, the maximum stroke of the deformation of the strain sensing part 40 can be controlled, which can protect the strain sensing part 40 and effectively avoid the situation that the strain sensing part 40 may be damaged due to excessive deformation.

[0078] like Fig.12As shown, the monitoring alarm mechanism 400 disposed in the radiation-proof lead plate door 70 is connected to the processor 50. The processor 50 can be built inside the radiation-proof lead plate door 70, or can be disposed outside the radiation-proof lead plate door 70. The processor 50 includes a communication module, and the communication module can have wireless communication capabilities. The communication module enables the processor 50 to establish a communication connection with an external remote monitoring system 60, and the external remote monitoring system 60 includes a scrolling screen 61 and an alarm.

[0079] When the roller 31 rotates relative to the roller shaft 34, the strain sensing signal generated by the strain sensing unit 40 can be fed back to the processor 50, and the processor 50 analyzes and processes the signal and sends a corresponding command signal to the external monitoring system. After receiving the alarm command, the alarm can send one or more alarm prompts including sound, flash, etc.

[0080] After analyzing and processing the strain sensing signal, the processor 50 can calculate the current settlement value of the corresponding lead plate 100 (which is a gradually increasing cumulative value), and transmit it to the remote monitoring system 60 in the form of a command signal, and finally display it through the scrolling screen 61.

[0081] The remote monitoring system 60 can be connected to multiple radiation-proof lead doors 70 equipped with the monitoring alarm mechanism 400, and can cyclically display the settlement status of the lead plates 100 on the multiple radiation-proof lead doors 70 (such as displaying the settlement value of the corresponding lead plate 100 that has settled) through the scrolling screen 61. When the settlement value of the lead plate 100 reaches the warning threshold, the corresponding settlement value (number) will change color and / or flash on the scrolling screen 61.

[0082] In addition, if Fig.12 As shown, an alarm light may be provided corresponding to each row of sedimentation values ​​on the scrolling screen 61. When a row of sedimentation values ​​on the scrolling screen 61 exceeds the early warning threshold, the alarm light corresponding to the row emits an alarm sound and / or flashes.

[0083] like Figure 1 , Figure 2 , Fig.12As shown, this patent also relates to a radiation-proof lead door that can be IoT-enabled. The radiation-proof lead door 70 includes a lead plate 100 fixed on a steel frame and the above-mentioned static settlement monitoring and alarm mechanism (i.e., the monitoring and alarm mechanism 400 shown in the figure, hereinafter referred to as the monitoring and alarm mechanism 400). The steel frame includes a frame 300 and a steel plate 200 formed by cross-connecting a plurality of columns 301 and a plurality of cross bars 302. The cross bars 302 shown in the figure extend along the XY plane and a plurality of cross bars 302 are arranged alternately in the XZ vertical plane, and the columns 301 extend along the XZ vertical plane and a plurality of columns 301 are arranged alternately in the ZY vertical plane. After the outer shell of the radiation-proof lead door 70 is arranged on the steel frame, the lead plate 100 is squeezed by the steel plate 200 and the frame 300, and the plate surface will be subjected to pressure F pressure.

[0084] The arm plate 10 of the monitoring alarm mechanism 400 is fixed on the crossbar 302 located at the upper part of the frame 300 and extends vertically downward. The side of the arm plate 10 facing the lead plate 100 is a vertical surface (i.e., the surface connected to the first stud 24 and the second stud 46).

[0085] After the U-shaped member 20 is fixed to the arm plate 10, the elastic portion 23 will be elastically deformed to press the left roller surface of the roller 31 against the plate surface of the lead plate 100. In the illustrated scheme, a rubber layer 33 is fixedly provided on the roller surface at this location to increase the static transmission capacity between the lead plate 100 and the roller 31.

[0086] Figure 1 In the illustrated solution, the monitoring alarm mechanism 400 is provided on both layers of crossbars 302 on the upper part of the frame 300. In specific implementation, the monitoring alarm mechanism 400 may also be provided only on the layer of crossbars 302 located at the uppermost part.

[0087] Only one monitoring alarm mechanism 400 may be arranged on the same crossbar 302, or a plurality of monitoring alarm mechanisms 400 may be arranged alternately along the length direction of the crossbar 302. Figure 2 shown.

[0088] like Fig.12 As shown, the monitoring alarm mechanism 400 is connected to an external processor 50, and the external processor 50 includes a communication module. The processor 50 including the communication module should be understood as including the processor 50 itself including the communication module and the processor 50 connected to the external communication module.

[0089] With the help of the communication module, the processor 50 can establish a communication connection with the remote monitoring system 60 through the Internet of Things communication gateway. The remote monitoring system 60 at least includes a scrolling screen 61 and an alarm device.

[0090] When the lead plate 100 settles, the settlement of the lead plate 100 can drive the matching roller 31 to rotate relative to the roller shaft 34, so that the strain sensing part 40 generates a changing strain sensing signal. After the emitted strain sensing signal is transmitted to the processor 50, after being analyzed and processed by the processor 50, the processor 50 will send a command signal (including multiple command signals such as analysis result command signal and alarm command signal) to the remote monitoring system 60.

[0091] After receiving the alarm command signal, the alarm device can emit an alarm prompt signal such as sound and / or flashing light.

[0092] After analyzing and processing the strain sensing signal, the processor 50 can calculate the (cumulative) settlement value of the corresponding lead plate 100 , and transmit the analysis result to the remote monitoring system 60 (in the form of a command signal), and finally update and display it through the scrolling screen 61 .

[0093] The remote monitoring system 60 can be connected to a plurality of radiation-proof lead plate doors 70 equipped with the monitoring alarm mechanism 400 , and can cyclically display a plurality of corresponding settlement values ​​through the scrolling screen 61 .

[0094] When the processor 50 analyzes that the settlement value of the lead plate 100 with the radiation proof lead plate door 70 has accumulated to / exceeds the preset warning threshold, the settlement value number corresponding to the radiation proof lead plate door 70 will change color and / or flash on the scrolling screen 61 to give an alarm prompt.

[0095] An alarm light is provided for each row of sedimentation values ​​on the scrolling screen 61. When a row of sedimentation values ​​on the scrolling screen 61 exceeds the early warning threshold, the alarm light corresponding to the row emits an alarm sound and / or flashes an alarm prompt.

[0096] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. The present invention can be improved in many aspects without violating the overall concept, and those familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
