Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a device and method capable of actively reporting the on-off status of a lead seal. Background Art

[0002] Line loss is an important comprehensive technical and economic indicator of power companies, and its level directly affects the economic benefits and profits of power companies. However, high-loss areas have long been a common problem for power supply companies, and an important factor causing this situation is theft of electricity by users. In recent years, tens of thousands of cases of electricity theft have been seized nationwide each year, and the amount of electricity charges and breach of contract electricity charges has reached tens of billions of yuan. However, even though power companies continue to strengthen relevant measures to combat electricity theft, the behavior of electricity theft by users still shows a trend of spreading and expanding.

[0003] Lead seals are disposable locks. Unless they are violently destroyed, they cannot be opened once they are sealed. Installing lead seals is an important step in reducing electricity theft and line loss. With the improvement of science and technology, conventional means of electricity theft such as loss of pressure and shunting can be remotely monitored through electric energy meters. However, since power companies currently cannot know when the lead seals are broken when they carry out their work, only when the meter reports an abnormality can the electricity inspector go to the site to check whether there is electricity theft, resulting in delayed and passive anti-electricity theft work. At the same time, some lead seal manufacturers are blinded by greed and illegally produce and sell lead seals of the same appearance, which greatly increases the difficulty of anti-electricity theft.

[0004] Therefore, in order to solve the above problem, the present invention proposes a device and method that can actively report the on-off status of the lead seal.

[0005] After searching, no public documents of the prior art identical or similar to the present invention were found. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and to propose a device and method that can actively report the on-off status of a lead seal, and can send information about the damaged lead seal when the lead seal is damaged, thereby turning passivity into initiative and more effectively combating electricity theft.

[0007] The present invention solves the practical problem by adopting the following technical solutions:

[0008] A device capable of actively reporting the on / off status of a lead seal, comprising: a packaging plastic box and a circuit inside thereof; the circuit comprising: a power module, a controller, a data storage module, a clock module, a current monitoring module, and a micro-power wireless module;

[0009] The controller is connected to the clock module, the micro-power wireless module and the data storage module respectively, and is used to control the clock module and the micro-power wireless module to work, and can read the data of each module and write it into the data storage module;

[0010] The controller is also connected to a current monitoring module, which is composed of a diode and monitors the on / off state of the circuit through the voltage across the diode;

[0011] The micro-power wireless module can be used to transmit data on the sealing status and the on-off time.

[0012] Two insulating wires extend outwardly from the two ends of the packaging plastic box, and the ends of the insulating wires are annular metal sheets for connecting with the cover screws of the electric energy meter.

[0013] Moreover, the power module uses a chip battery to supply power to the entire device.

[0014] Moreover, the data storage module is composed of a storage chip, which is used to store the unique identity information of the device and the data read by the controller.

[0015] Moreover, the clock module is a perpetual calendar clock, which is used to provide current time information.

[0016] A method for actively reporting the on / off status of a lead seal comprises the following steps:

[0017] Step 1: Insert two annular metal sheets into the threaded ends of two cover screws from the back of the electric energy meter terminal cover, and then tighten the cover screws to fix the cover to the electric energy meter. The two cover screws are connected through the current monitoring module on the inner side of the cover.

[0018] Step 2: After the sealed steel strands are passed through the screw lead sealing holes of the two covers from the outside of the electric energy meter cover and sealed, the two cover screws are connected by the steel strands on the outside of the cover; therefore, after the cover is sealed, the steel strands, the cover screws and the device capable of actively reporting the on / off status of the lead seal form a closed path in terms of physical connection;

[0019] Step 3. When the seal is broken, the closed path is opened. At this time, the controller reads the current time through the clock module and stores the time information in the data storage module. The controller then sends a signal to the substation concentrator through the micro-power wireless module, and sends its own identity information and time data in the data storage module to the concentrator. The seal installation location and the time of damage are transmitted to the main station of the power company through the concentrator uplink communication module.

[0020] Advantages and beneficial effects of the present invention:

[0021] The present invention proposes a device and method capable of actively reporting the on-off status of a lead seal, which can solve the problem that the current lead seal cannot record the time when it is damaged. The device capable of actively reporting the on-off status of a lead seal of the present invention integrates a power module, a controller, a data storage module, a clock module, a current monitoring module, and a micro-power wireless module, and has the advantages of small size, long life, not easy to be damaged, and reusable, and can realize active reporting of the on-off status of the lead seal.

[0028] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0029] A device that can actively report the on / off status of a lead seal, such as Figures 1 to 4 As shown, it includes: a packaging plastic box and a circuit inside it; the circuit includes: a power module, a controller, a data storage module, a clock module, a current monitoring module, and a micro-power wireless module;

[0030] The controller is connected to the clock module, the micro-power wireless module and the data storage module respectively, and is used to control the clock module and the micro-power wireless module to work, and can read the data of each module and write it into the data storage module;

[0031] The controller is also connected to a current monitoring module, which is composed of a diode and monitors the on / off state of the circuit through the voltage across the diode;

[0032] The micro-power wireless module can be used to transmit data on the sealing status and the on-off time.

[0033] Two insulating wires extend outwardly from the two ends of the packaging plastic box, and the ends of the insulating wires are annular metal sheets for connecting with the cover screws of the electric energy meter.

[0034] In this embodiment, the power module uses a chip battery to power the entire device.

[0035] In this embodiment, the data storage module is composed of a storage chip, which is used to store the unique identity information of the device and the data read by the controller.

[0036] In this embodiment, the clock module is a perpetual calendar clock, which is used to provide current time information.

[0037] A method for actively reporting the on / off status of a lead seal comprises the following steps:

[0038] Step 1: Insert two annular metal sheets into the threaded ends of two cover screws from the back of the electric energy meter terminal cover, and then tighten the cover screws to fix the cover to the electric energy meter. The two cover screws are connected through the current monitoring module on the inner side of the cover.

[0039] Step 2: After the sealed steel strands are passed through the screw lead sealing holes of the two covers from the outside of the electric energy meter cover and sealed, the two cover screws are connected by the steel strands on the outside of the cover; therefore, after the cover is sealed, the steel strands, the cover screws and the device capable of actively reporting the on / off status of the lead seal form a closed path in terms of physical connection;

[0040] Step 3. When the seal is broken, the closed path is opened. At this time, the controller reads the current time through the clock module and stores the time information in the data storage module. The controller then sends a signal to the substation concentrator through the micro-power wireless module, and sends its own identity information and time data in the data storage module to the concentrator. The seal installation location and the time of damage are transmitted to the main station of the power company through the concentrator uplink communication module.

[0041] The functions and effects of each module in the device are further explained below:

[0042] The device is mainly composed of the following modules: power module, controller, data storage module, clock module, current monitoring module, and micro-power wireless module. The functions of each module are as follows:

[0043] The power module uses a chip battery to power the entire device; the controller is composed of a microcontroller chip, which can control the operation of the clock module and the micro-power wireless module, and can read the data of each module and write it into the data storage module; the data storage module is composed of a storage chip, which is used to store the unique identity information of the device and the data read by the controller, and is directly connected to the controller; the clock module is a perpetual calendar clock, which can provide current time information and is directly connected to the controller; the current monitoring module is composed of a diode, which monitors the on-off state of the circuit through the voltage at both ends of the diode, and is directly connected to the controller; the micro-power wireless module can be used to transmit data such as the seal status and on-off time.

[0044] The power module, controller, data storage module, clock module, current monitoring module and micro-power wireless module are integrally encapsulated in a plastic shell. The plastic shell has only two wires facing the outside, and the ends of the wires are annular metal sheets for connecting to the terminal cover screws of the electric energy meter.

[0045] The working principle and working process of the present invention are:

[0046] First, Figure 1 The two annular metal sheets 1 in Figure 3 The end threaded parts of two cover screws 4 are respectively inserted into the back of the terminal cover of the middle electric energy meter, and then the cover screws are tightened to fix the cover to the electric energy meter. The two cover screws are connected on the inner side of the cover through the current monitoring module.

[0047] Will Figure 4 The steel strand 6 of the middle lead seal passes through the screw lead seal holes 5 of the two covers from the outside of the electric energy meter cover and is sealed. The two cover screws are connected by the steel strand on the outside of the cover. Therefore, after the cover is sealed, the steel strand 6, the cover screws 4 and Figure 1 The device that actively reports the on / off status of the lead seal forms a closed path in the physical connection.

[0048] When the power module starts to supply power, the diode in the current monitoring module is turned on, and current is generated in the closed path. At this time, the diode voltage is the conduction voltage, which is a small fixed value. When the lead seal is broken, the closed path is open, and the current drops to 0. At this time, the diode is not turned on, and the voltage across the diode is approximately equal to the power module voltage.

[0049] According to this principle, the voltage at both ends of the current monitoring module is input into the controller. When the voltage is less than a certain value M, all modules in the device do not act. When the voltage value is greater than the M value and exceeds 1 minute, the controller reads the current time through the clock module and stores the time information in the data storage module. After that, the controller sends a signal to the substation concentrator through the micro-power wireless module, sends its own identity information and time data in the data storage module to the concentrator, and transmits the seal installation location and the time of destruction to the main station of the power company through the concentrator uplink communication module.

[0050] It should be emphasized that the embodiments of the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
