Description

Electronic sealing device of electronic meter and smart electronic sealing system including same

[0001] The present invention relates to an electronic sealing system, and more particularly, to an electronic sealing device of an electronic meter and a smart electronic sealing system including the same.

[0002] Thermal energy can be supplied using electricity, gas, water, and other methods in various locations, including residential homes, commercial buildings, and industrial sites. Meters, such as power meters, gas flow meters, water flow meters, and heat meters, can be installed to measure thermal energy usage in each location. Each meter can display metering information, such as usage status and consumption, via a metering indicator to inform both suppliers and users. Furthermore, each meter can be sealed using a separate device to prevent manipulation of the metering information.

[0003] Lead was traditionally used to seal electricity meters for over 100 years. However, due to lead's environmental and human health hazards, the seals were replaced with plastic ones. The plastic seals cover the meter terminal cover and the modem storage space. The seal numbers are printed on the plastic seals, which are then entered into the computer system for management.

[0004] However, plastic seals require manual management of seal numbers, which reduces efficiency during sealing. Plastic seals also have low measurement reliability. Plastic seals can also cause environmental pollution due to carbon emissions during disposal. Because plastic seals must be individually checked for damage, tampering with the meter can delay corrective action.

[0005] The present invention is intended to solve the above-described problems, and an object of the present invention is to provide an electronic sealing device and an electronic sealing system including the same, which reduces the amount of waste discharged due to seal damage and improves the sealing operation method by combining a communication device and a sealing device.

[0121] In step S410, the seal number management module (3210) can input information of the meter (3100) and connect the seal identification unit (3250) in the same manner as step S310 described in FIGS. 10 and 11.

[0122] At step S420, the seal number management module (3210) can determine whether the information of the seal identification unit (3250) has changed. The information of the seal identification unit (3250) may include information on the sealing status of the terminal cover and / or the auxiliary cover. As an example, the information on the sealing status may include whether the current sealing status is open or closed. The sealing status information of the seal identification unit (3250) may be closed during sealing and open when the seal is released. When the sealing is completed again, the sealing status information of the seal identification unit (3250) may be changed to closed.

[0123] If the seal number management module (3210) determines that the information in the seal identification unit (3250) has not changed (NO), it can perform step S430 to search the seal information. If the seal number management module (3210) determines that the information in the seal identification unit (3250) has changed (YES), it can perform step S440 to change the seal information.

[0124] In step S430, the seal number management module (3210) can retrieve seal information. The seal number management module (3210) can retrieve information in the same manner as step S320 described in FIGS. 10 and 12.

[0127] At step S460, the seal number management module (3210) can transmit the changed seal information to the seal management server (3500). The seal management server (3500) can store and manage the changed seal information.

[0128] Figure 14 is a flowchart for exemplarily explaining the transmission task illustrated in Figure 8. Referring to Figures 7 and 14, the seal number management module (3210) can perform the task of transmitting untransmitted information.

[0129] Untransmitted information includes information that the seal number management module (3210) has to update for the meter (3100), terminal cover, and / or auxiliary cover, but has not transmitted to the seal management server (3500). The seal number management module (3210) can perform the task of transmitting untransmitted information regardless of the inquiry task (S300) or the sealing task (S400).

[0130] The seal number management module (3210) can repeatedly execute (LOOP) the task of transmitting unsent information. Accordingly, when the seal number management module (3210) is disconnected from the network (3400) and then reconnected, the seal number management module (3210) can automatically transmit unsent information to the seal management server (3500).

[0131] In step S510, the seal number management module (3210) may directly perform a request for transmission of untransmitted information or may receive a request from a sealing manager.
