POS decoder for monitoring and managing products with supervision code

Abstract

The invention relates to a POS decoder used to supervise products which are stuck with supervision codes, which is characterized in that a control circuit of the decoder uses a USB peripheral input interface circuit, a PS2 peripheral input interface circuit, a RS232 serial input interface circuit which are respectively connected with a center main control microprocessor, a reset circuit and a clock circuit are respectively connected with the center main control microprocessor, a large capacity data memory and a large capacity data buffer are respectively connected with the center main controlmicroprocessor, the center main control microprocessor is respectively connected with a wireless network transmitting circuit and a wired network transmitting circuit, and the wireless network transmitting circuit is connected with an antenna. Under the pre-condition that prior settlement and enterprise information systems are not affected, through decoding in real-time and transporting supervision code data to a supervision network, governments and enterprises are of help to achieve product traceability, enterprises in the circulation field are of help to achieve to ask for a ticket and a certificate and build electronic business machine account, the supervision demands of the governments in the circulation field can be achieved, and the POS decoder provides an assurance for the product traceability and a recall system.

Description

technical field [0001] The invention relates to a POS decoder for supervising products with supervising codes, in particular it is applied to shopping malls / supermarket POS systems or dealer purchase, sale and storage systems. Background technique [0002] At present, the General Administration of Quality Supervision, Inspection and Quarantine, the Ministry of Commerce, and the State Administration for Industry and Commerce have issued documents requiring that 69 products in 9 categories, including food and household appliances, must be 100% electronically supervised before they can be shipped and sold. In existing technologies, such as figure 1 As shown, the shopping mall / supermarket POS system or the dealer's invoicing system usually uses the output terminal of the scanning device in the scanning system to connect to various interfaces such as serial port, USB, PS2, etc., and then supports various interfaces such as serial port, USB, PS2, etc. The interface is connected t...

Problems solved by technology

However, this kind of shopping mall / supermarket POS system or dealer invoicing system does not yet have the function of unlocking the supervision code.

If all POS systems or dealers' invoicing systems are fully upgraded, the waste of resources will be huge in terms of time, manpower, material resources and financial resources.
