Obviously, the drawings in the following description are only embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.
[0016] Figure 1 This is a schematic diagram of an embodiment of a human body protection system provided by the utility model. DETAILED DESCRIPTION
[0017] The core of the utility model is to provide a mobile cabinet and a human body protection system thereof, which can ensure the personal safety of relevant operators entering the cabinet and avoid the occurrence of accidents of people being pinched.
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The implementation of a human body protection system provided by the utility model is as follows: Figure 1 As shown, Figure 1The present invention provides a schematic diagram of an embodiment of a human body protection system. Here, three cabinets 1 connected to each other are used as an example for explanation. However, in fact, it is not limited to three cabinets 1. It can also be any number of cabinets 1. This can be selected according to actual needs. Under normal circumstances, these cabinets 1 are closely arranged without leaving gaps in the middle, so that a larger number of cabinets can be accommodated in a space of a certain size, so that more medical devices, such as endoscopes, etc., can be stored. When it is necessary to open one of the cabinets 1, a corresponding opening instruction can be given first to control the movement of this cabinet 1, so that the space at the position of its cabinet door is expanded until it can accommodate the operator to walk in and take out the endoscope. After the endoscope is taken out, a closing instruction can be given to move the cabinet 1, so that the space in front of the cabinet door becomes smaller until it is next to the cabinet adjacent to it. When it is necessary to open the cabinet door of other cabinets 1, similar operations can be performed. It can be seen that by using this type of cabinet, the indoor space can be fully utilized, so that more medical devices such as endoscopes can be stored in a limited space. During the operation, these cabinets 1 will be frequently moved, and people will constantly move around. When a person enters and exits the area between the cabinets, there is a possibility that a person may be trapped between the cabinets 1 due to a failure of the cabinet 1. To avoid this situation, a human protection system is designed. Specifically, the human protection system may include a human sensing device 3 that is communicatively connected to the cabinet movement control device 2. It should be noted that the human sensing device mainly senses the person by detecting infrared rays, microwave signals, etc. emitted by the human body. Generally, there are the following types: (1) Human infrared sensing switch: It works by detecting infrared rays of a specific wavelength emitted by the human body. When the human body enters the sensing range, the switch will trigger an action; (2) Human proximity sensor: Based on the microwave Doppler principle, it uses a planar antenna as the sensing system and a microprocessor as the control to detect the movement of a human body or an object; (3) Thermal infrared human sensor: It is an infrared pyroelectric sensor that can detect a stationary human body. Through tiny mechanical movements, it can generate an identification signal regardless of whether the human body is moving or stationary; (4) Human microwave sensor: It uses the Doppler effect to detect human movement information by transmitting and receiving electromagnetic waves to achieve real-time monitoring of the human body;(5) Intelligent radar human body sensor: It is also based on the Doppler effect and can sense stationary human bodies. Any one or more of them can be selected for human body sensing according to actual needs. There is no limitation here. The cabinet movement control device 2 can be a controller, and each cabinet must have at least one to achieve the coordinated movement of multiple cabinets. The cabinet movement control device 2 on each cabinet is connected to the cabinet movement drive device 4 on the cabinet. The cabinet movement drive device 4 can be but not limited to a motor to output power to move the cabinet. In addition, the cabinet movement control device 2 on each cabinet 1 is also communicatively connected to the cabinet movement control devices 2 on other cabinets 1. In this case, the cabinet movement control devices 2 can transmit signals to realize simultaneous operation or stop and other operations. The human body sensing device 3 is used to transmit the sensed human body signal to the cabinet movement control device 2. The control device 2, the cabinet movement control device 2 is used to control the closing of the cabinet movement drive device 4 corresponding to it after receiving the human body signal and transmit it to the cabinet movement control device 2 on other cabinets 1. The cabinet movement control device 2 on other cabinets 1 is used to control the closing of the cabinet movement drive device 4 on other cabinets 1. In this case, not only can the cabinet that senses the human body signal stop moving during the closing process, but also the gas cabinet can stop moving. In this way, after the overall movement stops, the relevant personnel will not be sandwiched between the cabinets, and human protection is effectively performed. Moreover, when the relevant personnel leave the area between the cabinets, the human body sensing device 3 will not sense the human body signal, so the control can be released, and the cabinet movement control device 2 can control the cabinet movement drive device 4 to close, and at the same time, other cabinet movement drive devices 4 can be closed until the closing is completed. ;
[0020] It can be seen from the above technical scheme that in the embodiment of the above-mentioned human body protection system provided by the utility model, since it includes a human body sensing device communicatively connected to the cabinet movement control device, the cabinet movement control device on each cabinet is connected to the cabinet movement drive device on the cabinet, and the cabinet movement control device on each cabinet is also communicatively connected to the cabinet movement control devices on other cabinets. The human body sensing device is used to transmit the sensed human body signal to the cabinet movement control device, and the cabinet movement control device is used to control the closing of the cabinet movement drive device corresponding to it after receiving the human body signal and transmit it to the cabinet movement control devices on other cabinets, and the cabinet movement control devices on other cabinets are used to control the closing of the cabinet movement drive devices on other cabinets, thereby ensuring the personal safety of the relevant operators entering therein and avoiding the occurrence of pinching accidents.
[0021] In a specific embodiment of the above human body protection system, continue to refer to Figure 1, and may also include an emergency stop device 5 arranged on the cabinet 1, which is used to emergency stop the cabinet moving drive device 4 after being activated. It should be noted that the emergency stop device is a safety device used to quickly stop the operation of a machine or system in an emergency, and can be of the following types: (1) Emergency stop button: usually in the shape of a red mushroom head, eye-catching and easy to identify, used to immediately cut off the power supply of the machine in an emergency; (2) Pull-cord switch: trigger an emergency stop by pulling a rope, usually used for larger machines or situations where multiple points of control are required around the machine; (3) Foot switch: emergency stop is achieved by stepping on the switch, often used when the operator needs to use both hands to operate the machine; (4) Wireless emergency stop device: uses wireless signal transmission and can be within a certain range Trigger emergency stop at any position; (5) Emergency stop master switch with lock / tag function: After emergency stop, specific operation is required to reset to ensure safety; (6) Intelligent emergency stop: Integrates modern electronic technology, may include self-diagnosis function, status indication and communication capability with control system; (7) Emergency stop and button indication device: Combines emergency stop function and status indication to provide more intuitive operation feedback; (8) Pull-wire emergency stop button: Allows emergency stop operation at any position within the pull-wire length range; (9) Emergency stop switch: An essential device for automated machines and systems, capable of immediately stopping the machine or system in an emergency. The design and use of the emergency stop device described here must comply with relevant safety standards and regulatory requirements to ensure that personnel and equipment safety can be effectively protected in an emergency. The use of this emergency stop device 5 in this embodiment is a hardware protection measure. If the software protection fails, after triggering this emergency stop device 5, all circuits will be cut off to ensure the safety of personnel. It can be seen that this further improves the safety of the entire system.
[0022] In another specific embodiment of the above human body protection system, continue to refer to Figure 1 The emergency stop device 5 can be arranged on the connection line 6 between the cabinet moving drive device 4 and the power supply (shown in the figure). It should be noted that: Figure 1 The power supply in the figure is located on the inner side of the cabinet perpendicular to the paper surface, so it cannot be Figure 1 As shown in the figure, the cabinet moving drive device 4 can be powered by the power supply to realize the movement of the cabinet 1, and when the emergency stop device 5 located between the two is triggered, the connection between the two will be disconnected. After the cabinet moving drive device 4 is powered off, it loses power and will no longer move the cabinet 1, realizing the emergency stop of the cabinet 1, thereby ensuring the personal safety of the people inside.
[0023] In another specific embodiment of the above-mentioned human protection system, the emergency stop device 5 may include an emergency stop button arranged on the inner surface of the cabinet 1, and a switch component electrically connected to the emergency stop button. The switch component is closed in a normal state to connect the cabinet movement drive device to the power supply, and the switch component is disconnected after the emergency stop button is activated to cut off the power to the cabinet movement drive device. It can be seen that this provides a way to stop the movement of the cabinet by emergency power off, providing more safety configurations, and the height of the setting position of the emergency stop button can be preferably 1.5 meters to 1.8 meters above the bottom surface of the cabinet, which makes it more convenient for relevant personnel to quickly reach the emergency stop button with their hands to perform emergency stop operations more efficiently. Of course, other forms of emergency stop devices can be selected according to actual needs, and can also be set in other suitable positions, which is not limited here. In addition, in a further embodiment, an emergency stop device 5 can be preferably provided on each cabinet 1, and each emergency stop device 5 is electrically connected together to achieve linkage, such as Figure 1 As shown by the horizontal line in the figure, the emergency stop devices 5 on each cabinet are directly connected together. When one of the emergency stop devices is activated, the other emergency stop devices are also activated, so that the cabinet movement drive devices 4 on each cabinet are powered off at the same time, thereby achieving synchronous stopping and moving of each cabinet, avoiding the situation where one cabinet stops while other cabinets are still moving.
[0024] In a preferred embodiment of the human protection system, each cabinet 1 is equipped with a human body sensing device 3, and each cabinet 1 is equipped with an alarm device ( Figure 1(not shown), the cabinet movement control device 2 is used to control the alarm device to send out an alarm signal when the human body sensing device 3 senses the human body and detects that the cabinet movement drive device 4 is performing the cabinet closing operation. It should be noted that the cabinet movement control device 2 performs a state judgment after receiving the signal that a person enters between any two cabinets. At this time, there are two situations. The first is that the device is in the process of opening the door. At this time, there is no possibility of locking a person inside, so the protection signal will not be triggered; the second situation is that if the device is in the process of closing the door, there is a possibility of locking a person inside at this time. At this time, it is necessary to trigger a human protection signal to stop the movement of the cabinet, and an alarm signal can be sent at this time to let the control personnel outside know that there is an emergency and remind them not to continue to perform the door closing operation. The alarm will not be lifted until the person moves out from between the cabinets, and the cabinet movement control device 2 can continue to control the cabinet to move. It can be seen that the use of this alarm device can further improve the safety of the entire system and make the operations between different personnel more reasonable and efficient. In a further embodiment, two human body sensing devices 3 may be preferably installed on each cabinet 1, and the human body sensing devices 3 are respectively installed on the left and right sides of the front of each cabinet 1. Figure 1 In this case, no matter whether a person enters the cabinet 1 from the left or right side, he can be quickly sensed, thereby improving the sensing efficiency and better ensuring personal safety. The height of the installation position of the human body sensing device 3 can be preferably 1.5 meters to 1.8 meters from the bottom of the cabinet, which is more in line with the height of an average person. By ensuring that it is highly consistent with the position of the human body, the presence of the human body can be sensed more quickly, thereby issuing an instruction to stop the movement of the cabinet more quickly, and the safety is higher. Of course, it can also be set at other heights according to actual needs, which is not limited here.
[0025] In another preferred embodiment of the human body protection system, the human body sensing device 3 can be preferably a beam photoelectric switch, a diffuse reflection photoelectric switch or a safety grating. Among them, the beam photoelectric switch is a photoelectric sensor, which consists of a transmitter and a receiver. The two parts are usually placed on both sides of the path through which the detection object passes. When the light beam emitted by the transmitter is blocked by an opaque object, the receiver will detect the interruption of the light beam and output a switch control signal. Its advantages include: long detection distance, the beam photoelectric switch can achieve a detection distance of several meters or even tens of meters, few restrictions on the detection object, and can detect almost all objects, including glass, plastic, wood, liquid, etc., short response time, because the light itself propagates fast, and the sensor circuit is composed of electronic parts and does not contain mechanical working time, so the response time is very short, high resolution, can detect tiny objects and high-precision position detection, non-contact detection, detection can be achieved without contacting the detection object, so it will not cause damage to the object and the sensor, which is conducive to the long-term use of the sensor. The diffuse reflection photoelectric switch is an industrial automation control element that uses the photoelectric principle to detect the position and existence of an object. The diffuse reflection photoelectric switch emits an infrared beam or laser through the transmitter. The beam is reflected by the object and reaches the receiver. The receiver monitors the infrared signal. If the signal is not blocked, the signal is directly returned to the transmitter in the air to cause the distance measurement. If it is blocked by the target object, the detector will not be able to receive the signal, and a switch signal will be sent to control the start and stop of the equipment. It can realize non-contact detection. Even if the surface of the detected object is not smooth or irregular, it will not affect the detection result. Unlike the photoelectric cross-beam switch, the diffuse reflection photoelectric switch does not need to set a reflector or reflector. It only needs to place the transmitter and the receiver on the same end face. Therefore, it is more flexible and convenient, with the advantages of long service life, no color influence, and easy installation. The detection distance of the diffuse reflection photoelectric switch is determined by the color of the target. If the target is black or dark, the reflected light is weak, so the detection distance will be relatively short; while bright objects can provide a longer detection distance.The above-mentioned safety grating is a photoelectric device used to protect personal safety. It usually exists in pairs, divided into a transmitter and a receiver. The safety grating is mainly used to protect operators from injuries when they approach mobile machinery. The safety grating consists of a set of transmitters and receivers. The transmitter emits a series of infrared beams, and the receiver contains multiple light sensors. If an object or person enters the grating area and blocks the beam, the receiver will not be able to receive the complete signal, thereby triggering the safety mechanism and sending a stop signal to the monitoring device. The beam of the safety grating is emitted in a specific frequency sequence to ensure that only the beam from the corresponding transmitter can be received by the receiver. Identification, avoid interference from other infrared light sources, usually connected to a safety relay, when an object is detected, it can automatically remove the dangerous power source, or suspend the function of the grating in a specific program. The safety grating can reach the highest safety level, that is, safety level 4. Compared with traditional mechanical barriers, the safety grating provides a more free and flexible protection method, which can reduce the fatigue of operators and simplify the installation, maintenance and repair of equipment. The safety grating is an important safety protection device in the field of industrial automation. It monitors and judges whether the human body or object enters the dangerous area in real time, thereby ensuring the safety of personnel and avoiding accidents. It should also be noted that any of the above can be selected according to actual needs, and can be freely combined, that is, multiple types of human body sensing devices can be used on a cabinet at the same time, which is not limited here.
[0026] In another preferred embodiment of the above-mentioned human body protection system, it may also be preferred to include a voice sensing device that is communicatively connected to the cabinet movement control device 2, the voice sensing device is used to convert the sensed voice signal into a control closing instruction and transmit the control closing instruction to the cabinet movement control device 2, the cabinet movement control device 2 is used to control the closing of the cabinet movement drive device 4 corresponding to it after receiving the control closing instruction and transmit it to the cabinet movement control devices 2 on other cabinets, and the cabinet movement control devices 2 on other cabinets are used to control the closing of the cabinet movement drive devices 4 on other cabinets. It should be noted that this voice sensing device, also known as a voice recognition system or a voice control device, is an electronic device that can recognize and respond to human voice commands and can be integrated into various applications, including smart homes, mobile devices, cars, robots, and other scenarios that require voice interaction. Its working principle is as follows: a voice sensing device usually includes one or more microphones to capture sound, a signal processor to analyze sound signals, and a voice recognition engine to convert sound into executable commands. Regarding voice recognition technology, modern voice recognition systems use complex algorithms, such as deep learning, to improve recognition accuracy. They can recognize different voice patterns, intonations, and dialects. Regarding natural language processing, advanced voice sensing devices can not only recognize voice, but also understand and process natural language, allowing users to interact with the device in a more natural way. After adding this voice sensing device here, when an emergency occurs where the door is about to close and someone is about to be pinched, if the person inside the cabinet door is not convenient to reach the emergency stop device, he can immediately shout out relevant words. After being recognized by this voice sensing device, the cabinet door can be quickly controlled to stop closing. It can be seen that this provides a redundant design that can better ensure the safety of personnel.
[0027] In addition, continue to refer to Figure 1 , Figure 1 Also shown is a door closing limit switch 7, which is used to detect whether the door is closed.
[0028] The above embodiments realize the human protection function of the mobile cabinet. Taking the endoscope storage cabinet as an example, in the actual application environment, the cleaning personnel will frequently enter and exit the cabinet. By adopting this human protection system, it is possible to provide safety protection from both software and hardware aspects, providing better protection for the safety of the cleaning personnel in the later stage. The first software protection is that the human protection switch will be triggered after the lens-taking personnel enters the cabinet, and the controller of the corresponding cabinet will transmit the signal to the remaining cabinets through communication, and all cabinets will lock the motor. The second software protection is that if the communication transmission between the cabinets fails, all cabinets will turn on the protection function and lock the motor until the communication returns to normal. Hardware protection is that in addition to software protection, all cabinets are equipped with a hardware protection device of the emergency stop switch. If the software protection fails, all circuits will be cut off after the emergency stop switch is triggered to ensure the safety of personnel.
[0029] The mobile cabinet provided by the utility model has a higher safety because it includes any of the above human protection systems, and can avoid the situation where a person is caught when the cabinet door is closed.
[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
