Description

Technical Field

[0001] The invention relates to the field of lead seal structure design, in particular to an intelligent electric energy meter electronic lead seal based on a load control special transformer acquisition terminal. Background Art

[0002] The lead seals of electric energy meters are mainly divided into mechanical lead seals and electronic lead seals. With the development of science and technology, the traditional manual inspection method of whether the lead seals of electric energy meters are broken or damaged has become outdated. At present, after the new installation or replacement of electric energy meters, they will be applied to the electric energy meters, and the status and number of the lead seals of the electric energy meters will be manually recorded on site. If the lead seals of the electric energy meters are broken or damaged during this period, they can only be checked during the next periodic inspection. There will be a serious lag problem, which will greatly hinder the power company from determining whether there is electricity theft and when it is broken or damaged. The electronic lead seals currently used to prevent electricity theft of electric energy meters use lead seal strips to penetrate the seals. A deadlock is formed through the meter cover, screws and two holes in the lead seal. If the meter cover needs to be removed, the lead seal will be damaged. At the same time, there is no remote real-time monitoring of whether the lead seal is damaged. Regardless of whether it is a mechanical lead seal or an electronic lead seal, it is only a technology for preventing breakage or damage. There is no effective real-time monitoring of whether the lead seal is damaged and the means of damage. In the actual use of electricity meter lead seals, almost all the lead seals used on site are mechanical lead seals, and electronic lead seals are rarely used. If the time when the lead seal is broken or damaged can be monitored at the same time, the operation of the on-site electricity meter can be further monitored to determine whether there is electricity theft and enhance the electricity meter's anti-theft capability.

[0003] After searching, the utility model patent with authorization number CN205984130U discloses an electronic seal for electric energy meters based on RFID technology, including an induction layer, a support sheet is arranged under the induction layer, an RFID electronic tag chip and a large-area induction antenna connected thereto are encapsulated in the induction layer, and a buckle is arranged under the support sheet. The utility model improves the existing button-type electronic seal into a slightly larger sheet structure, which not only improves the reading and writing distance of the electronic seal, but also cannot be disassembled after encapsulation, which can effectively prevent the occurrence of electricity theft and increase the safety of electricity use. The electronic seal in this solution is not equipped with a real-time detection system for anti-electricity theft, and the data of the tag chip cannot be transmitted synchronously, and does not have the function of realizing real-time monitoring.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1 to 5 As shown, it shows a schematic diagram of the structure of the present invention, the electronic seal of the smart electric energy meter based on the load-controlled special transformer acquisition terminal includes an electronic seal device 1 and a load-controlled special transformer acquisition terminal 2, the electronic seal device 1 and the load-controlled special transformer acquisition terminal 2 are used in conjunction with each other, and the electronic seal device 1 is further divided into an electronic seal part 11 and a seal belt 12 fixedly connected thereto;

[0034] The electronic lead seal part 11 comprises a lower cover 111, an upper cover 112, and a lead seal sheet 113. The lower cover 111 is fixedly connected to the upper cover 112, and the lead seal sheet 113 is placed in a cavity formed by the lower cover 111 and the upper cover 112.

[0035] The lead sealing belt 12 includes a belt head 121 and a tie portion 122 . The belt head 121 is fixedly connected to the tie portion 122 . A lead sealing buckle 3 is provided on the belt head 121 . The tie portion 122 is in a long strip shape and has teeth arranged on the upper surface.

[0036] The interior of the seal sheet 113 is composed of a flexible bearing layer 4, a seal chip 5 and a seal antenna 6. The seal chip 5 adopts RFID chip technology. The seal antenna 6 is composed of a layer of 18μm thick aluminum or copper plus a 100μm thick release paper. The flexible bearing layer 4 adopts PET as the bearing layer of the antenna pattern.

[0037] Furthermore, the lead seal buckle 3 is a clamping groove 31 in which an inclined and fixed clamping opening 32 is provided. The inner cavity of the clamping opening 32 is provided with clamping teeth, and the teeth provided on the cable tie part 122 are used in conjunction with the clamping teeth.

[0038] The receiving signal frequency of the lead sealing chip 5 is 840 MHz to 920 MHz.

[0039] In this embodiment, the electronic lead sealing device 1 is mainly composed of two parts: an electronic lead sealing part 11 and a lead sealing belt 12. The electronic lead sealing part 11 is fixedly connected by a lower cover 111 and an upper cover 112 to form a closed cavity. The lead sealing sheet 113 is located in the cavity between the lower cover 111 and the upper cover 112. The lead sealing sheet 113 includes a flexible bearing layer 4, a lead sealing chip 5 and a lead sealing antenna 6. The flexible bearing layer 4 adopts PET material as a bearing layer of the antenna pattern. The lead sealing core 5 adopts RFID chip technology and supports signal transmission in the frequency range of 840MHz to 920MHz. The lead sealing antenna 6 is composed of a layer of 18μm thick aluminum or copper plus a 100μm thick release paper, and is responsible for receiving and sending signals.

[0040] The sealing belt 12 includes a belt head 121 and a tie portion 122, which are fixedly connected.

[0041] according to Figure 3 As shown, the sealing chip 5 is internally integrated with a sensing element 51. When the sealing chip 5 is in a normal closed state, the sensing element 51 can generate a first signal and send it to the sealing antenna 6. If the sealing chip 5 is illegally opened or damaged, the sensing element 51 generates a second signal different from the first signal and informs the load-controlled special transformer collection terminal 2 via the sealing antenna 6, so that the load-controlled special transformer collection terminal 2 can detect abnormal conditions in time and send an alarm to the background management subsystem 7.

[0042] The sensing element 51 integrates five components, namely, a silicon chip, a modulator, an oscillator, a digital logic circuit, and a memory. The sensing element 51 encrypts the transmitted data to ensure the security and confidentiality of the data and prevent unauthorized access and tampering.

[0043] Furthermore, the background management subsystem 7 is connected to the load-controlled special transformer collection terminal 2, and is used to centrally manage and monitor the status information of all installed electronic sealing devices 1, including real-time monitoring, data decoding, processing and other functions, and promptly respond to various abnormal situations and take corresponding measures.

[0044] In this embodiment, when the electronic lead sealing device 1 is in a normal closed state, the sensing element 51 inside the lead sealing chip 5 generates and sends a first signal to the lead sealing antenna 6, and the lead sealing antenna 6 transmits the signal to the load-controlled special transformer acquisition terminal 2. The terminal 2 confirms that the lead sealing state is normal and uploads this information to the background management subsystem 7 every 15 minutes. If the electronic lead sealing device 1 is illegally opened or damaged, the sensing element 51 will detect the change and generate a second signal different from the first signal. The second signal is transmitted to the load-controlled special transformer acquisition terminal 2 via the lead sealing antenna 6. The terminal 2 identifies the abnormal situation and sends an alarm to the background management subsystem 7. The background management subsystem 7 responds in time and takes corresponding measures to notify relevant personnel to check and handle.

[0045] There is a circuit in the electronic seal part 11 and the seal belt 12 fixedly connected thereto. After being tightened in the normal binding direction, the circuit in the seal buckle 3 and the seal belt 12 forms a closed loop, so that the electronic components inside the electronic seal can work normally. The seal belt 12 and the seal buckle 3 can only be fastened and cannot be withdrawn, forming a lock. If the electronic seal is to be opened, the seal belt 12 must be destroyed. Destroying the seal belt 12 will definitely destroy the integrity of the circuit, causing the electronic seal to fail to operate normally.

[0046] Reference Figure 4 and Figure 5 As shown, the dedicated transformer acquisition terminal 2 is provided with a reader 21 and a radio frequency module 22 to demodulate and decode the received signal. The load control dedicated transformer acquisition terminal 2 can collect information on the electronic lead seal device 1 on the smart electric energy meter within 10 meters.

[0047] The dedicated transformer collection terminal 2 is provided with an antenna 23, and the antenna 23 supports wireless communication to ensure the timeliness of the collected data.

[0048] The load-controlled special transformer collection terminal 2 can collect information on the electronic lead sealing device 1 on the smart electricity meter within 10 meters, and can realize one-to-many information collection within a range of 10 meters. The load-controlled special transformer collection terminal 2 has a built-in reader / writer 21 and a radio frequency module 22, which can demodulate and decode the received RFID signal, and is equipped with an antenna 23 for wireless communication to support data transmission with the background management subsystem.

[0049] The electronic seal part 1 and the seal belt 2 fixedly connected thereto have the appearance of a conventional plastic seal, and a waterproof coating is provided on the surface to enhance its durability and reliability in harsh environments such as moisture, rain and snow.

[0050] The specific installation and implementation process of the electronic seal of the smart energy meter based on the load-controlled special transformer acquisition terminal of the present invention is as follows: when installing the smart energy meter, the electronic seal device 1 is installed at the same time, and the assembled electronic seal device 1 is placed at the position where the energy meter needs to be sealed. After the seal tape passes through the part to be sealed, the tie part 122 is inserted into the seal buckle 3, so that the clamping teeth and the teeth of the tie part are engaged with each other to form a closed loop, and the electrical connection status of the entire system is checked to ensure that the seal chip 5 and the seal antenna 6 are working properly, and then the load-controlled special transformer acquisition terminal 2 is installed. Generally, the installation distance between the smart energy meter and the load-controlled special transformer acquisition terminal is not more than 10 meters, so that the seal antenna 6 enters the working mode and is connected with the load-controlled special transformer acquisition terminal within 10 meters. The electronic seal device 1 establishes a connection with the terminal 2, and the electronic seal device 1 sends its own coded information to the reader 21 through the seal antenna 6. The reader 21 transmits a radio frequency signal of a certain frequency through the antenna 23. When the electronic seal enters its working area, the seal is activated and the information stored in it is read. The reader 21 and the radio frequency module 22 demodulate and decode the received signal, and finally transmit the valid information to the background management subsystem 7 for processing. The electronic seal device 1 contains a seal antenna 6 for transmitting radio frequency signals between the seal and the reader), which is used to communicate with the radio frequency antenna. The reader 21 reads the electric energy meter of the seal information, and the background management subsystem 7 is responsible for decoding, processing and applying the data read by the reader 21.
