[0028] The following will describe in detail various non-limiting embodiments of the present application with reference to the accompanying drawings.

[0029] See Figure 1 , which shows an intelligent gas meter security chip issuing system in an embodiment of the present application. The intelligent gas meter security chip issuing system includes an industrial control computer, a chip issuing machine, a security platform, a cipher machine, and a card reader.

[0030] The industrial control computer is communicatively connected to the card reader. For example, the communication connection method between the industrial control computer and the card reader is a USB connection, that is, the industrial control computer is USB-connected to the card reader.

[0031] The industrial control computer is electrically connected to the chip issuing machine. For example, the electrical connection method between the industrial control computer and the chip issuing machine is a serial port connection, that is, the industrial control computer is serially connected to the chip issuing machine.

[0032] The industrial control computer is communicatively connected to the cipher machine. For example, the communication connection method between the industrial control computer and the cipher machine is a network connection, that is, the industrial control computer is network-connected to the cipher machine. Another example is that the communication connection method between the industrial control computer and the cipher machine is a local area network connection through a network switch; that is, the system further includes a network switch, and the industrial control computer and the cipher machine are connected through the network switch for local area network connection.

[0033] The system may include several industrial control computers, and the network switch is connected to the several industrial control computers. As Figure 2 shown, 2 industrial control computers are deployed in the network switch.

[0034] In one implementation, the cipher machine is communicatively connected to the security platform. The security platform is used to determine the transmission protocol and the protection key, and export the issuance key information in ciphertext according to the transmission protocol and the protection key. It can be understood that the cipher machine is used to store the issuance key information exported by the security platform. During the key export process, the cipher machine and the security platform determine the transmission protocol and the protection key, and the key information used for issuance is exported in ciphertext and stored in the cipher machine device. It should be noted that the key is protected by the transmission key, and the key is transmitted in ciphertext during the transmission process. In this way, the key filling service provides a local and remote interaction channel, and at the same time intensively manages the local production and issuance data, and overall maintains the user information, production and issuance information, order information, task data, etc. of production and issuance, providing a data and interaction platform for production and issuance work and production inspection work.

[0035] The cipher machine is used to store the issuance key information exported by the security platform, and send the issuance key information to the industrial control computer. Among them, the cipher machine and the industrial control computer can be communicatively connected through the TCP / IP communication protocol, and the key is protected and exported through encryption by the security chip main control machine.

[0036] The industrial control computer is used to control the chip dispenser to load and unload materials, and control the card reader to perform chip issuance operations by using the issuance key information. In one implementation, local issuance software is pre-set in the industrial control computer. That is to say, the local issuance software is deployed in the industrial control computer, and the industrial control computer uses the local issuance software to control the chip dispenser to load and unload materials. In addition, the industrial control computer can send operation instructions to the card reader through the USB communication protocol so that chip issuance operations can be performed on the card reader. In this way, the card reader and the chip are communicatively connected through the ISO7816 communication protocol. In this way, the key is protected and exported through encryption by the security chip main control. In this way, due to the deployment of local cipher machine equipment, chip issuance work in local and remote modes is supported. The chip issuance software (i.e., the local issuance software) is deployed on the industrial control computer, and communicates with the cipher machine, production and issuance equipment, and card reader through the network port, serial port, and USB port respectively. The chip issuance software obtains the key data of each chip from the cipher machine, establishes a file structure through the card reader (i.e., the card reader), and writes the key into the security chip. The chip issuance software synchronously controls the production and issuance equipment to perform automatic loading and unloading, and synchronizes the issuance information to the production and issuance management system.

[0037] Such as Figure 2As shown, the intelligent gas meter security chip issuing system may further include an air pump; the air supply port of the air pump is connected to the chip issuing machine, and the air pump is used to provide power for the chip issuing machine. That is, the air supply port of the air pump is connected to the chip issuing machine to provide power for the chip issuing machine; the air pump provides power for multiple chip issuing machines at the same time.

[0038] The system includes several cipher machines, and the several cipher machines are deployed in a primary and standby manner; the chip issuing machine is used to support several tracks to be connected to the industrial control computer through serial ports at the same time, and a card reader is set for each track. For example, as Figure 2 shown, there are 2 cipher machines, which are deployed in a primary and standby manner; each chip issuing machine supports the simultaneous issuing of four tracks and is connected to the industrial control computer through a serial port for the control of loading and unloading, and a card reader is set for each track.

[0039] It can be seen from the above technical solutions that the present application provides an intelligent gas meter security chip issuing system, and the intelligent gas meter security chip issuing system includes an industrial control computer, a chip issuing machine, a security platform, a cipher machine, and a card reader; the industrial control computer is communicatively connected to the card reader, the industrial control computer is electrically connected to the chip issuing machine, and the industrial control computer is communicatively connected to the cipher machine; the cipher machine is communicatively connected to the security platform; the cipher machine is used to store the issuing key information exported from the security platform and send the issuing key information to the industrial control computer; the industrial control computer is used to control the chip issuing machine for loading and unloading, and use the issuing key information to control the card reader to perform chip issuing operations. It can be seen that both the cipher machine and the security platform in this system store the issuing key information, and the industrial control computer can use the issuing key information to provide local and remote interaction channels, and overall maintain user information, production issuing information, order information, task data, etc. for production issuing work and production inspection work, providing a data and interaction platform. The industrial control computer is respectively connected to the cipher machine, the chip issuing machine, and the card reader. The industrial control computer can obtain the key data of each chip from the cipher machine, establish a file structure through the card reader, and write the key data into the security chip. The industrial control computer synchronously controls the chip issuing machine for automatic loading and unloading, and synchronizes the issuing information to the production issuing management system. This system can effectively solve the problems of many fault points and low issuing efficiency in the current chip issuing system.
