Description

Technical Field

[0001] The present invention relates to the technical field of intelligent opening and closing doors, and in particular to an intelligent opening and closing door for safe management of indoor environment of a transformer substation and a monitoring and alarm method. Background Art

[0002] The indoor safety management systems of substations are mostly placed in separate rooms, and people and pets can enter and exit the rooms directly through the doors, which has poor security and is not convenient for detecting the entry of designated permitted personnel. Unregistered permitted personnel are prohibited from entering. The intelligence is poor and it cannot detect and identify people entering and leaving, which has certain defects.

[0003] The existing general intelligent access control device can realize the function of automatic unlocking, but does not have the function of automatically opening and closing the door body. It is still necessary to manually turn the door handle to open the door after automatic unlocking. When in an emergency, it is not conducive to the designated authorized personnel to quickly enter and deal with the emergency, or quickly escape from the substation; most general intelligent doors do not have an alarm function. Even if they have an alarm function, the alarm is only a warning on the door body, which cannot meet the needs of the substation that need to be handled in a timely manner;

[0004] Substations are generally located in remote areas with a large amount of dust. General smart doors do not have a cleaning function, which will lead to long-term accumulation of dust and affect the smoothness of the opening and closing of the door body.

[0005] The defects of existing intelligent opening and closing doors are:

[0006] 1. Patent document WO2019037277A1 discloses a pet cage with a door, wherein the door has an adjustable opening degree. The pet cage includes a square pet cage body consisting of a top plate, a side plate and a bottom plate. The front side plate serves as a pet cage door and can be opened and closed. The door includes a first door panel and a second door panel arranged parallel to each other. The first guide groove and the second guide groove corresponding to the first door panel and the second door panel are respectively arranged on opposite sides of the upper, lower, left and right frame parts of the front side of the pet cage body corresponding to the door. The upper and lower edges of the first door panel are provided with a first guide wheel that cooperates with the first guide groove. The left and right edges of the second door panel are provided with a second guide wheel that cooperates with the second guide groove. The pet cage with an adjustable opening door of the present invention has a simple structure, is easy to manufacture, install and operate, can effectively control the opening degree of the pet door as needed, and has high practicality. However, the pet cage with a door in the above-mentioned public document mainly considers how to adjust the opening degree of the door, and does not consider that the existing doors for indoor environmental safety management of substations cannot be opened and closed intelligently, and have poor practicality;

[0007] 2. Patent document KR1020210112152A discloses a smart door, in which an opening is formed between a first space provided at the front of the structure and a second space provided at the rear of the structure, and a door is provided in the opening, wherein the first space and the second space open and close the door; a processing chamber is formed therein, forming a first box opening for connecting the processing chamber and the first space, and a second box opening for connecting the processing chamber and the second space. A first adjustment door is assembled to the adjustment box, exposed to the first space, and opens and closes the first box opening; and a second adjustment door is assembled to the adjustment box, exposed to the second space, and opens and closes the second box opening. The smart door according to the present invention can store clothes or shoes in the adjustment box by opening the first adjustment door of the clothes processing device only to people with an authentication code, and the user can store the second adjustment door indoors by opening the second adjustment door. It has the advantage of being able to take out old clothes or shoes, but the smart door in the above-mentioned public document mainly improves the convenience of use by opening the smart door only to people with an authentication code, and does not take into account the problem that the existing smart opening and closing door does not have an abnormal alarm function, and has poor safety;

[0008] 3. Patent document KR1020210123077A discloses a smart door, which is arranged between a first space at the front of the structure and a second space at the rear of the structure, and the door is arranged in the structure to open and close the first space and the second space; and a handle arranged on the passage door, wherein the handle includes a first handle arranged on the passage door and exposed to the first space, and a first handle arranged on the passage door and exposed to the second space; a moving handle including the second handle; and a handle driver, which is arranged on the inspection door, provides a driving force to the moving handle, and selectively moves the handle in the front and rear directions. According to the present invention, since the handle is arranged not to protrude from the inspection door, it is difficult for an outsider to apply an external force to the handle, and through this, indoor safety can be improved, but the smart door in the above-mentioned public document mainly considers how to improve indoor safety, and does not consider the problem that the existing smart opening and closing doors are prone to unsmooth movement after long-term use;

[0009] 4. Patent document WO2022010074A1 provides a smart door, and more specifically, provides a smart door, which includes an entrance door, which is arranged between a first space defined in front of a structure and a second space defined behind the structure, and is configured to open and close a connecting passage connecting the first space and the second space; a storage part, which is arranged on one side of the entrance door and is arranged between the first space and the second space together with the entrance door and is configured to store delivered goods at room temperature or low temperature, a support, which extends vertically along the boundary between the entrance door and the storage part, and a lock, which is arranged on the support and is engaged to lock or unlock the entrance door and each of the storage parts. However, the smart door in the above-mentioned public document mainly considers how to improve the practicality and functionality of the door, and does not consider the problem that the existing smart opening and closing doors have poor cleaning effects when in use.

The cleaning mechanism cleans the hard-to-clean positions inside, thereby improving and maintaining the performance of the intelligent opening and closing door for a long time.

[0070] In a preferred but non-limiting embodiment of the present invention, the cleaning mechanism includes: an anti-stuck module, a cleaning module, a laser rangefinder 27, a protective frame 28, a connecting block 29, a brush 30, a roller 31, a storage slot 32, a dust storage frame 33, a pull ring 34, a storage box 35, a micro electric push rod 36, a connecting block 37, and a cleaning brush 38.

[0071] See also Figure 4 , Figure 6 and Figure 7 An embodiment of the present invention is: an intelligent opening and closing door for indoor environmental safety management of a substation, including a laser rangefinder 27 and a cleaning brush 38, an anti-stuck module is installed at the bottom of the opening and closing door body 15, and the anti-stuck module is used to improve the smoothness of the movement of the opening and closing door body 15, the anti-stuck module includes a protective frame 28 installed on the bottom surface of the opening and closing door body 15, the other left inner wall of the slot 3 and the left outer wall of the storage plate 17 are both installed with a laser rangefinder 27, and the laser rangefinder 27 is used to measure the distance between the opening and closing door body 15 and the laser rangefinder 27 itself, wherein a group of laser rangefinders 27 is located on the side and lower side of the electromagnet 18.

[0072] like Figure 3 or Figure 4 As shown, two groups of symmetrically arranged connecting blocks 29 are installed at the bottom of the protective frame 28, and brushes 30 are installed at the bottom of the four groups of connecting blocks 29. The front of the door frame 1 is provided with symmetrically arranged storage grooves 32, and a dust storage frame 33 is embedded and installed inside the storage grooves 32, and the cross-section of the dust storage frame 33 is an "L"-shaped structure, and a pull ring 34 is installed on the front of the dust storage frame 33. The storage grooves 32 are located below the storage plate 17, and the bottom of the brush 30 is in contact with the bottom wall of the slot 3. The storage grooves 32 are in an inverted "U"-shaped structure. The storage grooves 32 are located on both sides of the inlet and outlet 2, and symmetrically arranged rollers 31 are installed at the bottom of the protective frame 28, and the rollers 31 are located in the middle of the two groups of connecting blocks 29.

[0073] like Figure 6 As shown, a cleaning module is installed inside the storage slot 32, and the cleaning module is used to sweep foreign objects in the slot 3 into the dust storage frame 33. The cleaning module includes a storage box 35 symmetrically installed on the back of the door frame 1, and a micro electric push rod 36 is installed on the rear wall of the storage box 35. A connecting block 37 is installed at the output end of the micro electric push rod 36, and a cleaning brush 38 is installed at the bottom of the connecting block 37. The connecting block 37 is located at the rear of the dust storage frame 33, and the bottom of the cleaning brush 38 is in contact with the bottom wall of the slot 3 and the dust storage frame 33.

[0074] Furthermore, during the movement of the opening and closing door body 15, the roller 31 will roll on the bottom wall of the slot 3, and the brush 30 can sweep the foreign matter in the slot 3 into the dust storage frame 33 as the opening and closing door body 15 moves, so that the place where the roller 31 passes can be kept clean. When it is necessary to clean the foreign matter in the dust storage frame 33, first start the micro electric push rod 36 in the storage box 35 to drive the connecting block 37 to move, so that the cleaning brush 38 can push the foreign matter in the dust storage frame 33 to the front end, and then pull the pull ring 34 outward to pull the dust storage frame 33 out of the storage slot 32, and then the foreign matter collected in the dust storage frame 33 can be processed, thereby improving the smoothness of the movement of the opening and closing door body 15 to a certain extent.

[0075] like Figure 8 As shown, the monitoring and alarm system of the intelligent opening and closing door includes: an opening and closing module, a monitoring and alarm module, an anti-stuck module and a cleaning module.

[0076] The monitoring alarm module is interconnected with the opening and closing module, the anti-stuck module provides services for the opening and closing module, and the cleaning module provides services for the anti-stuck module.

[0077] The opening and closing module opens and closes the door body 15 through the servo motor switch, and the monitoring alarm module determines whether the person to be entered is a designated permitted person through the monitoring unit, the scanning unit and the information storage unit. If it is determined that the person is a designated permitted person, the opening and closing module opens and closes the door body, otherwise, the opening and closing module does not work.

[0078] The anti-stuck module measures the distance between the opening and closing door body 15 and itself through a laser rangefinder to determine the degree of opening and closing of the opening and closing door body 15. When closing, the opening and closing door body 15 moves to the right. When reaching the predetermined distance with the laser rangefinder, the opening and closing module stops working, and the opening and closing door body 15 stops moving. Similarly, when opening, the opening and closing door body 15 moves to the right. When reaching the predetermined distance with the laser rangefinder, the opening and closing module stops working. In addition, the opening and closing module can clean foreign objects in the slot through the components of the anti-stuck module, thereby improving the smoothness of the opening and closing module.

[0079] The cleaning module pushes out the foreign matter removed by the anti-stuck module through the micro electric push rod 36, thereby improving the cleaning effect to a certain extent, and also leaving more space for the foreign matter removed by the anti-stuck module in the future.

[0080] Furthermore, the monitoring and alarm method of the intelligent opening and closing door is as follows:

[0081] S1. Before using the intelligent opening and closing door, first install the door frame 1 and the storage box 4 at a suitable position, and enter the personnel information and work card information allowed to enter the substation into the information storage 23;

[0082] S2. When a person needs to enter the substation, the infrared scanner 25 in the scanning unit is used to scan and detect whether there are people or animals near the door frame 1. When a person wants to enter the substation, he needs to take out the corresponding work card and stick it on the work card sensing unit 21, so that the monitoring unit 19 can scan and read the information of the placed work card;

[0083] S3. On the contrary, when the information of the person entering detected by the work card sensing unit 21, the facial recognition unit 22 and the infrared scanner 25 is a person who is designated to enter the substation, the electromagnet 18 is powered off, and then the servo motor 6 in the connection box 5 is started, and then the sprocket 7 can be driven to rotate counterclockwise, so that the chain 8 can drive the connecting piece 1 9 and the connecting piece 2 12 to move, and then the opening and closing door body 15 can be driven to no longer block the entrance and exit 2, and then the person can enter the substation;

[0084] S4. During the movement of the opening and closing door body 15, the roller 31 will be driven to roll on the bottom wall of the slot 3, and the brush 30 on the connecting block 29 will be driven to clean the bottom wall of the slot 3, so that the area where the roller 31 passes can be kept clean, thereby improving the smoothness of the movement of the opening and closing door body 15 to a certain extent, and the brush 30 can sweep foreign objects in the slot 3 into the dust storage frame 33 as the opening and closing door body 15 moves.

[0085] In step S2, the following steps are also included:

[0086] S21, in the process of reading the work card information, the facial recognition unit 22 is used to identify the facial information of the person entering, and it is determined whether it is consistent with the read work card information. If the information recognized by the facial recognition unit 22 is inconsistent with the information read by the work card sensing unit 21, the sound and light alarm 26 is activated, and the photo and video are taken and sent to the monitoring center to prompt the security management personnel to handle the alarm information in time;

[0087] In step S3, the following steps are also included:

[0088] S31, after the internal scanning unit detects that the person has entered the substation, the electromagnet 18 on the storage plate 17 is energized, the servo motor 6 rotates clockwise, driving the sprocket 7 to rotate clockwise, so that the chain 8 can drive the connecting piece 1 9 and the connecting piece 2 12 to move in the opposite direction of the direction of coming, until the iron frame 16 can fit the electromagnet 18, and then the entrance and exit 2 can be blocked by opening and closing the door body 15;

[0089] In step S4, the following steps are also included:

[0090] S41. When it is necessary to clean the foreign objects in the dust storage frame 33 in the future, start the micro electric push rod 36 in the storage box 35, and then it can drive the connecting block 37 to move, so that the connecting block 37 can drive the cleaning brush 38 to move, and then the cleaning brush 38 can push the foreign objects in the dust storage frame 33 to the front end, and then pull the pull ring 34 outward to pull the dust storage frame 33 out of the storage slot 32, thereby improving the functionality and practicality of the opening and closing door body 15 to a certain extent.

[0091] Working principle: When the infrared scanner 25 detects that a person wants to enter the substation, the corresponding work card needs to be taken out and attached to the work card sensing unit 21, so that the monitoring unit 19 can scan and read the placed work card information, and then use the facial recognition unit 22 to identify the facial information of the person entering, and determine whether it is consistent with the read work card information. If the information recognized by the facial recognition unit 22 is inconsistent with the information read by the work card sensing unit 21, the sound and light alarm 26 is activated, and the photo video is taken and sent to the monitoring center. On the contrary, when the information of the person entering detected by the work card sensing unit 21, the facial recognition unit 22 and the infrared scanner 25 is a person designated to enter the substation and the scanned information is consistent, the electromagnet 18 is powered off, and then the servo motor 6 is started, driving the sprocket 7 to rotate counterclockwise, so that the chain 8 can drive the connector 1 9 and the connector 2 12 to move, so that the opening and closing door body 15 no longer blocks the entrance and exit 2, and then the person can enter the substation;

[0092] During the movement of the opening and closing door body 15, the roller 31 will be driven to roll on the bottom wall of the slot 3, and the brush 30 on the connecting block 29 will be driven to clean the bottom wall of the slot 3, so that the place where the roller 31 passes can be kept clean, thereby improving the smoothness of the movement of the opening and closing door body 15 to a certain extent, and the brush 30 can sweep the foreign matter in the slot 3 into the dust storage frame 33 as the opening and closing door body 15 moves. When it is necessary to clean the foreign matter in the dust storage frame 33, start the micro electric push rod 36 to drive the connecting block 37 to move, so that the cleaning brush 38 can push the foreign matter in the dust storage frame 33 to the front end, and then pull the pull ring 34 outward to pull the dust storage frame 33 out of the storage slot 32, and then the foreign matter collected in the dust storage frame 33 can be processed.

[0093] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
