[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] like Figure 1-Figure 2 As shown, an intelligent lead sealing device for a total meter at a transformer substation metering gateway comprises a lead sealing box 1 and a lead sealing rope 2 arranged on the lead sealing box 1. The lead sealing box 1 is provided with a lead sealing rope insertion hole 3 for passing the lead sealing rope 2, and the lead sealing rope 2 is made of ferromagnetic material.
[0018] like Figure 3 and Figure 4 As shown, a spring 5, an electromagnet 6, an MCU microcontroller unit and a battery are provided in the lead seal box 1. One end of the spring 5 is fixedly connected to the lead seal box 1, and the other end of the spring 5 is fixedly connected to the electromagnet 6. When the electromagnet 6 is powered on, it is magnetically adsorbed and connected to the lead seal rope 2. The on and off state of the electromagnet 6 is controlled by the MCU microcontroller unit, and the battery is used to power the MCU microcontroller unit.
[0019] A pressure sensor 4 is also provided in the lead sealing box 1, and the pressure sensor 4 is used to send a pressure signal to the MCU microcontroller unit; when the spring 5 is squeezed and deformed by the electromagnet 6, the spring 5 squeezes the pressure sensor 4 to generate a pressure signal.
[0020] The seal box 1 is also provided with an indicator light for indicating the seal state; when the electromagnet 6 is powered on, the indicator light is green, indicating that the seal is normal; when the electromagnet 6 is powered off, the indicator light is red, indicating that the seal is released.
[0021] The lead seal box 1 is also provided with a card reading module, which is connected to the MCU micro control unit and is used to identify the authorization card.
[0022] The lead seal box 1 is also provided with a face recognition module, which is connected to the MCU microcontroller unit and is used to recognize the facial information of the authorized person.
[0023] The lead sealing box 1 is also provided with a communication module, and the communication module is used to connect to the server.
[0024] Use of this embodiment: When the seal needs to be removed, the staff will report the work plan to the management platform. After approval, they can choose facial recognition authorization or authorization card. After arriving at the designated work location, the staff passes the verification through facial recognition or reading the ID card, and the MCU microcontroller controls the electromagnet 6 to turn off the power, and the electromagnet 6 no longer absorbs the seal rope 2. The indicator light turns red, indicating that the seal is removed, and the staff can then pull out the seal rope 2. The MCU microcontroller uploads the seal removal information to the server of the management platform through the communication module.
[0025] When it is necessary to reseal, the staff will pass the sealing rope 2 through the sealing rope jack 3, and then manually squeeze the spring 5 to squeeze the pressure sensor 4 to generate a pressure signal. The pressure sensor 4 sends the pressure signal to the MCU micro-control unit, and the MCU micro-control unit controls the electromagnet 6 to turn on the power state. The electromagnet 6 absorbs the sealing rope 2, and the indicator light turns green, indicating that the sealing is normal. The sealing rope 2 cannot be pulled out under the action of magnetic attraction. The MCU micro-control unit uploads the normal sealing information to the server of the management platform through the communication module.
[0026] In the description of the present invention, words indicating orientation or positional relationship such as "inside", "outside", "upper", "lower", "front", and "back" are only used to facilitate the description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0027] The above is only one embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications made without departing from the idea of the present invention are all within the protection scope of the present invention.
