Electronic Seal Monitoring System Based on Public Wireless Communication Network

technical field

The invention belongs to the technical field of electronic communication, and relates to an electronic seal monitoring system based on a public wireless communication network, in particular to a measuring instrument electronic seal monitoring system.

Background technique

Whether measuring instruments in today's society are effectively supervised affects every aspect of our lives. According to relevant laws and regulations, measuring instruments such as electronic scales, fuel dispensers, gas dispensers, taxi mileage meters, electric energy meters, gas meters, heat meters, and water meters, which are directly used for transaction settlement, should be subject to the first compulsory verification before installation. After passing the verification, it can be installed and put into use. However, driven by huge interests, criminals are increasingly cheating on these measuring instruments, and the methods are becoming more and more sophisticated, making it hard to guard against. Usually, the functional department of metrology supervision will add lead seals or seals to these measuring instruments, but because the lead seals or seals currently used are either easy to be copied and replaced, or have low tamper-proof performance and are easy to be disassembled, so common Measuring lead seals or seals are useless to some high-tech cheating methods and are useless, resulting in many disputes and complaints, bringing heavy workload to the quality supervision department, and seriously affecting social harmony and stability. Measurement supervision is not only related to the operating efficiency of enterprises and institutions, but also related to the daily expenses of thousands of households. The supervisory function of the metrological supervision department has attracted increasing attention from the general public and the government, and anti-cheating techniques and means will continue to be strengthened.

In addition, the existing traditional lead seals of electric meters, water meters, gas meters, and weighing instruments can only be checked by visual inspection, which means that traditional lead seals are easily damaged and modified, causing economic losses; secondly, traditional lead seals It cannot be recognized by information equipment, and data cannot be collected in a timely and convenient manner, so it can no longer meet the requirements of modern enterprise information management. Therefore, it is absolutely necessary to improve the prior art.

More than one monitor terminal constitutes the monitoring layer of the system, each monitor terminal acts as a network node, and transmits the collected data information to the upper layer; the monitoring layer works in a low-power sleep mode, and works at a set time interval (1s~1h or longer) scan the lead sealing equipment under the jurisdiction (each monitoring device can supervise 500 lead sealing equipment), once the scanning detects that the lead sealing line is broken, record the alarm date, time, ID code , and immediately upload to the server, and then enter sleep mode again;

More than one electronic seal constitutes the equipment layer of the system. The circuit board of the electronic seal detects whether the shell is opened abnormally and whether the seal line is broken. If the seal line is damaged or the electronic seal shell is opened abnormally , the electronic lead seal immediately sends an alarm message through the wireless bluetooth module on its circuit board to realize the protection of the lead seal of the measuring instrument;

The wireless communication between the monitor terminal and the electronic lead seal is realized by the Bluetooth 4.0 technology protocol, and its most important feature is extremely low power consumption in operation and standby.

Beneficial effect

The use of the lead seal monitoring system based on the public wireless communication network is an effective measure to prevent cheating in the sales, use and verification of measuring instruments. Measurement supervision is not only related to the operating efficiency of enterprises and institutions, but also related to the daily expenses of thousands of households. The invention can automatically realize the remote violation supervision of the electronic lead sealing device of the measuring instrument. The wireless networking method adopted by this system has the advantages of wide coverage area, flexible networking method and timely and accurate alarm; its electronic lead seal adopts low power consumption chip design, which can ensure the long-term reliable operation of the system. This system achieves electronic and informational management of lead seals and improves the daily inspection and supervision of lead seals by the metrology department, which can effectively improve the management efficiency of the quality inspection department. It has extremely high practical application value and has a broad market prospect.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Fig. 1 to Fig. 3, a kind of electronic seal monitoring system of the present invention comprises server 1, GSM module 3, monitor terminal 4 and several electronic seals 5;

The server is connected to the GSM module through the TTL/USB converter 2; the GSM module is connected to the monitor terminal through the public wireless communication network; the monitor terminal is connected to the electronic seal through the wireless signal.

The server, the TTL/USB converter and the GSM module constitute the application layer of the system, and the GSM module transmits the collected data information to the server to realize the system application function;

More than one monitor terminal constitutes the monitoring layer of the electronic seal monitoring system. The monitoring equipment works in a low-power sleep mode, and scans the lead sealing equipment under its jurisdiction according to the set time interval (1s~1h or longer) when working (each The monitoring equipment can supervise 500 sets of lead-sealed equipment), once the scan detects that the lead-seal line is disconnected, it will record the alarm date, time, and ID code, and immediately upload it to the server, and then enter the sleep mode again.

More than one electronic seal constitutes the system equipment layer, installed inside the protected measuring instrument, responsible for seal line protection, disconnection alarm and ID code transmission; low power consumption, button battery power supply (working time of more than one year), electronic Sealed core components can be reused.

The working principle and process are as follows:

When performing lead sealing after the measuring instrument verification is completed, the core part of the measuring instrument 12 is wound and bound with the lead sealing wire 6, and then the two ends of the lead sealing wire 6 are respectively inserted into the wire tightening device 16, and the lead sealing wire 6 will be sealed. Automatic locking; then connect the two ends of the lead seal wire 6 to the terminal 11 respectively, and the button battery 10 is packed into the circuit board 9; That is to start running. At this time, the lead seal of the measuring instrument can only be removed by cutting the lead seal line 6 or destroying the electronic lead seal 5 .

The electronic seal monitoring system operates normally, and the electronic seal 5 will not send a signal when it is in good condition. Once the seal wire 6 is damaged or the electronic seal 5 is opened abnormally, the electronic seal 5 will pass through the circuit board 13 immediately. The wireless bluetooth module 8 sends an alarm message, and the monitor terminal 4 scans and receives the alarm message, and immediately reports the message to the server 1 through the GPRS wireless communication network, and the server 1 queries the database through the alarm message (time, ID code) to confirm that it has been illegally destroyed The name, location and unit information of the measuring instruments, the staff of the relevant quality inspection department will conduct on-site illegal inspection and handling of illegal sabotage based on the server inspection information.

The electronic seal monitoring system directly uses the GPRS public wireless communication network to realize remote data transmission, and the alarm information is sent to the server in the form of SMS, which is suitable for applications with a small number of points and public network coverage.
