[0057] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0058] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a power box door opening monitoring alarm device based on RFID identification, including: a power box 1, a camera 2, an RFID identification device 3, an audible and visual alarm 4, a signal transmission device 5, a battery 6 and a photovoltaic panel 7, a control console 8, a power box door pulley 9, an electromagnet 10, an induction module and an online management platform.

[0059] The power box 1 comprises: a power box base 101, a power box enclosure 102, a power box door 103, and a power box top cover 104, which together form a box structure and constitute the main body of the power box.

[0060] The photovoltaic panel 7 is installed on the top of the power box cover 104, and is used to absorb solar energy during the day and store the electric energy converted from solar energy in the storage battery 6. The storage battery 6 is installed on the upper side of the power box enclosure 102 to provide electric energy for the power box door opening monitoring alarm device. The photovoltaic panel 7 interacts with the online management platform in real time. The online management platform calculates the light irradiance of sunlight irradiating the ground, and adjusts the light receiving angle of the photovoltaic panel in real time, thereby maximizing the power generation efficiency of the photovoltaic panel.

[0061] The camera 2 , the RFID recognition device 3 , the sound and light alarm 4 , and the signal transmission device 5 are all installed on the battery 6 and face the power box door 103 .

[0062] Camera 2 is used to shoot the operator's operating steps and attire from multiple angles throughout the entire process. Camera 2 is connected to the online management platform. Camera 2 transmits the images and videos it shoots to the online management platform, thereby enabling real-time online supervision of the operator's operating steps and work process.

[0063] In a preferred but non-limiting embodiment of the present invention, the camera 2 has an edge computing function, which can automatically identify whether the staff's behavior is illegal, and upload the video to the online management platform in real time, so as to supervise the operator.

[0064] like Figure 4 , Figure 5 , Figure 7 As shown, the power box door 103 includes a left door and a right door, which are arranged in parallel horizontally and are both opened or closed by a transverse movement.

[0065] Specifically, combined Figure 5 , Figure 6 and Figure 8 As shown, the structures of the left door and the right door are completely symmetrical. Taking the left door as an example, a pulley support frame 901 is provided on both sides of the bottom of the left door, and a pulley 9 is installed inside the pulley support frame 901 through a pulley shaft 902. A drive motor protection shell 904 is also provided at the bottom of the left door, and a drive motor 903 for driving the pulley 9 to rotate is provided inside the drive motor protection shell 904. The output end of the drive motor 903 is coaxially connected to the sliding shaft 902, and the pulley 9 is driven to rotate by driving the sliding shaft 902 to rotate, thereby driving the left door and the right door to open or close.

[0066] The driving motor 903 is connected to the online management platform and the storage battery 6, and is powered by the storage battery 6. The power box door 103 is also provided with an operating table 8 for controlling the opening or closing of the power box door 103. The operating table 8 is provided with a door opening touch button 802 and a door closing touch button 803, both of which are connected to the online management platform. The door opening touch button 802 can control the driving motor 903 to rotate forward to realize the door opening operation. The door closing touch button 803 controls the driving motor 903 to rotate reversely to realize the door closing operation.

[0067] Specifically, under the control of the door opening touch button 802, the driving motor 903 rotates forward, generating power to push the power box door 103 to open, thereby opening the power box door 103. Under the control of the door closing touch button 803 and the door closing command issued by the online management platform, the driving motor 903 rotates reversely, generating power to push the power box door 103 to close, thereby closing the power box door 103.

[0068] Furthermore, two slideways 109 are symmetrically arranged on the front side of the power box base 101 for the left and right door pulleys to move left and right, respectively. Both ends of each slideway 109 are provided with a sliding groove 105 vertically connected thereto, which is used for the two pulleys 9 thereon to move into the sliding groove 105 to limit the left and right positions when the left and right doors are fully opened or fully closed.

[0069] An electromagnet 10 for adsorbing the drive motor protection shell 904 is disposed on one side of the sliding groove 105 away from the slideway 109. The exterior of the drive motor protection shell 904 has a single magnetism, and the electromagnet 10 can change its magnetic pole by changing the direction of the current, thereby achieving adsorption or repulsion of the drive motor protection shell 904. Specifically, the electromagnet 10 is powered by a battery and is connected to the door opening touch button 802 and the door closing touch button 803. The door opening touch button 802 and the door closing touch button 803 can change the magnetic pole of the electromagnet 10.

[0070] like Figure 8 As shown, in a preferred but non-limiting embodiment of the present invention, the sensing module includes a first limit sensor 11 and a second limit sensor 12, which are respectively arranged on two sliding grooves 105 located on both sides of the same slideway 109, and are located on the side walls of the two sliding grooves 105 close to each other. The identification signals and judgment results of the first limit sensor 11 and the second limit sensor 12 correspond to the following Table 1.

[0071] Table 1 The first limit sensor and the second limit sensor jointly determine the state of the power box door

[0072]

[0073] like Figure 8As shown, when the power box door 103 is in the closed state, the first limit sensor 11 and the second limit sensor 12 jointly determine that the power box door 103 is in the closed state, and the drive motor 903 is not powered.

[0074] An electric current with a magnetic field opposite to that of the drive motor protective shell 904 is passed through the electromagnet 10. According to the magnetic field principle of "like charges repel and opposite charges attract", the drive motor protective shell 904 is adsorbed inside the sliding groove 105 by magnetic attraction, thereby closing the power box door 103 and keeping the power box door 103 in a closed state under the restriction of the sliding groove 105.

[0075] like Fig. 9 As shown, under the control of the door opening touch button 802, the magnetic pole 10 that can be controlled by current is fed with a current of the same magnetic field as the driving motor protection shell 904, and according to the magnetic field principle of "like repels like, opposites attract", the power box door 103 is moved away from the power box 1, from the sliding groove 105 to the inside of the slideway 109. At the same time, the door opening touch button 802 controls the driving motor 903 to pass a positive current; under the action of the positive rotation of the driving motor 903, a force is generated to push the power box door 103 to open, and the power box door 103 is opened.

[0076] Under the action of the drive motor 903, the power box door 103 moves along the slide 109. When the power box door 103 starts to move, the current passed through the electromagnet 10 in the magnetic field with the same magnetic properties as the drive motor protective shell 904 can be converted into a current passed through the magnetic field with the opposite magnetic properties to the drive motor protective shell 904 through the online management platform. According to the magnetic field principle of "like charges repel and opposite charges attract", the magnetic pole 10 controlled by the current begins to generate suction with the drive motor protective shell 904, and then starts waiting for the drive motor protective shell 904 to reach the specified position of the power box door sliding slot 105.

[0077] like Fig.10 As shown, when the drive motor 903 pushes the power box door 103 to the maximum open position, the pulley 9 located on the inner side of each power box door 103 is near the sliding groove 105 on the outer side of the power box base 101. At this time, the electromagnet 10 generates a magnetic attraction force on the drive motor protective shell 904, driving the drive motor protective shell 904 to move to the inside of the sliding groove 105.

[0078] like Fig.11As shown, the electromagnet 10 generates suction force on the driving motor protection shell 904, so that the power box door 103 moves toward the inside of the power box 1 and is limited by the sliding groove 105; after the second limit sensor 12 captures the signal, it is determined through the power box door center limit sensor 11 and the power box door frame limit sensor 12 that the power box door 103 has completed the opening task, and the driving motor 903 stops supplying power.

[0079] from Figure 11-Figure 10 - Figure 9-Figure 8 The reverse process is the process from opening to closing of the power box door 103.

[0080] like Fig.11 As shown, when the power box door 103 is in the open state, the power box door center limit sensor 11 and the power box door frame limit sensor 12 jointly judge that the power box door 103 is in the open state, and the drive motor 903 is not powered. The magnetic pole 10 that can control the magnetic current is passed through the current of the magnetic field with the opposite magnetic field to the drive motor protection shell 904. According to the magnetic field principle of "like poles repel, opposite poles attract", the power box door 103 is fixed in this position to ensure that the power box door 103 is continuously in a fully open state.

[0081] like Fig.10 As shown, under the control of the door closing touch button 802 or the door closing command issued by the online management platform, the electromagnet 10 is fed with a current of the same magnetic field as the drive motor protection shell 904, and according to the magnetic field principle of "like charges repel, opposite charges attract", the power box door 103 is moved to the outside of the power box 1. At the same time, the drive motor 903 is fed with a reverse current; under the action of the reverse rotation of the drive motor 903, a force is generated to push the power box door 103 to close, so that the power box door 103 is closed. After the power box door 103 starts to move along the power box door slide 109 under the action of the drive motor 903, the current passed into the electromagnet 10 with the same magnetic field as the drive motor protective shell 904 is converted into a current passed into the magnetic field with the opposite magnetic field to the drive motor protective shell 904. According to the magnetic field principle of "like charges repel and opposite charges attract", the electromagnet 10 begins to generate suction with the drive motor protective shell 904, and then starts waiting for the drive motor protective shell 904 to reach the specified position of the power box door sliding slot 105.

[0082] like Fig. 9 As shown, when the driving motor 903 pushes the power box door 103 to the fully closed position, the magnetic pole 10 whose magnetic properties can be controlled by electric current generates suction force on the driving motor protective shell 904, drawing it closer.

[0083] like Figure 8As shown, the suction force generated by the magnetic pole 10 with current-controllable magnetism on the driving motor protection shell 904 is used to realize the movement of the power box door 103 into the power box 1 and firmly fix it; after the power box door center limit sensor 11 and the power box door frame limit sensor 12 capture the signal, the power box door center limit sensor 11 and the power box door frame limit sensor 12 jointly judge that the power box door 103 has completed the closing task, and the driving motor 903 stops supplying power.

[0084] like Figure 4 As shown, in a preferred but non-limiting embodiment of the present invention, the pressure-relief sealing bag 107 is fixedly mounted on the side of the power box door 103 close to the middle of the power box, and the pressure-relief spring 106 is fixed inside the pressure-relief sealing bag 107 of the power box door.

[0085] The use of the pressure-relief spring 106 and the pressure-relief sealing bag 107 can effectively prevent external wind and sand from blowing into the power box, and improve the outdoor operating environment of the power box. During the closing process of the power box door, the pressure-relief spring 106 can store the energy generated by the spring while reducing the shaking of the power box door 103. During the opening process of the power box door, the pressure-relief spring 106 releases the stored energy while increasing the initial opening speed of the power box door 103, thereby assisting the opening of the power box door 103.

[0086] Furthermore, the sealing strip 108 is arranged on one side of the power box door 103 close to the inside of the power box, and is a "mouth"-shaped structure, which surrounds the power box door 103 and is used to improve the sealing of the overall structure of the power box when the power box door 103 is closed, thereby preventing the invasion of external wind, sand and dust.

[0087] The sound and light alarm 4 is connected to the signal transmission device 5. Preferably, the signal transmission device 5 is a 5G signal transmission device. The sound and light alarm 4 and the 5G signal transmission device are both connected to the online management platform. The sound and light alarm 4 is used to send out a sound and light alarm when the power box 1 is in an abnormal state. The aforementioned abnormal state is shown in Table 2 below. The signal transmission device 5 is used to start when the sound and light alarm 4 is working and transmit the alarm signal to the online management platform.

[0088] The RFID identification device 3 is matched with the RFID device carried by the power worker. If the RFID information matches successfully, an RFID matching signal is sent to the online management platform.

[0089] The first limit sensor 11, the second limit sensor 12 and the RFID identification device 3 are linked to achieve the effect of double verification, so as to comprehensively judge the situation of the power box according to the state of the power box door and the RFID matching situation, and judge whether it is necessary to start the sound and light alarm to sound an alarm, thereby increasing the reliability of equipment operation. If the first limit sensor 11 and the second limit sensor 12 jointly determine that the power box door 103 is in a closed state, the camera 2, the sound and light alarm 4, and the 5G signal transmission device 5 are all in a standby state; if the first limit sensor 11 and the second limit sensor 12 jointly determine that the power box door 103 is in a non-closed state, the camera 2, the sound and light alarm 4, and the 5G signal transmission device are all in an operating state; thereby achieving energy saving and consumption reduction.

[0090] The control panel 8 is located on the power box base 101 and is electrically connected to the battery 6. The infrared sensor 801, the door opening touch button 802, and the door closing touch button 803 are all located on the control panel 8 and are distributed up and down. The infrared sensor 801 can sense when a human body is close to the power box.

[0091] If the infrared sensor 801 detects that an object moves in front of the power box door 103, the camera 2, the RFID recognition device 3, the sound and light alarm 4, and the signal transmission device 5 are all activated, and the RFID recognition device searches for the surrounding RFID signals. If the RFID information matches successfully, the door can be opened to prepare, thereby realizing double detection of the situation around the power box and increasing the reliability of the operation of the power equipment. The online management platform can be connected to multiple power boxes 1 at the same time, and can collect the operating status of multiple power boxes 1 at the same time, meeting the requirements of the digital age for smart devices.

[0092] There are 8 working conditions of the power box, as shown in Table 2.
