Description

A kind of novel tag read-write equipment

Technical field

The present invention relates to a kind of novel tag read-write equipment, belong to electronic information field.

Background technology

Tag read-write equipment device is mainly used in the management of active electronic label, to the ID of the active electronic label in range of receiving fast identification and parameter thereof accurately read and write, avoid skip and misread, thereby causing the mistake identification of active electronic label representative object; Two kinds of on-the-spot wired communication interfaces are optional, are convenient to on-the-spot construction and installation.Tag read-write equipment device is based on embedded design, has merged microelectric technique, information sensing technology, and the sci-tech product of ICT (information and communication technology), can be used for the management of active electronic label, the situation of real-time monitoring active electronic label.And adopt the read-and-write device recognition speed of single-chip microcomputer slow, and process energy difference, management capacity is low, and real-time can not get ensureing.

Summary of the invention

Problem for existing, the invention provides a kind of novel tag read-write equipment, can carry out accurately the working condition of tower machine, monitor in real time.

The technical solution used in the present invention is:

A novel tag read-write equipment, its structural feature is:

Comprise ARM7 processor, and the 2.4G signal transmitting and receiving module, power module, wired communication interface module, the data-carrier store that are connected with ARM7 processor respectively;

ARM7 processor is for receiving and analyzing 2.4G signal transmitting and receiving module and wired communication interface module by signal and output a control signal to other module; 2.4G signal transmitting and receiving module is for receiving the data that active electronic label sends and transferring to ARM7 processor, send to active electronic label the data that ARM7 transmits; Power module is for providing ARM7 processor and the required electric energy of other modules; Wired communication interface module is for the wire communication of ARM7 processor data; Data-carrier store is for the storage of ARM7 processor operational factor, and power down is not lost.

Preferably, described power module comprises: AC/DC converter, DC/DC converter;

AC/DC converter is connected with DC/DC converter, and DC/DC converter is connected with ARM7 processor, and external communication high pressure is converted to applicable direct supply, electric energy is provided to ARM7 processor and other modules.

Preferably, described wired communication interface module comprises: the RS232 interface being connected with ARM7 processor respectively, 485 interfaces;

By the configuration to device parameter, ARM7 selects the interface type of wire communication afterwards automatically in startup, and RS232 interface and 485 interfaces select one.

Preferably, described ARM7 processor adopting LPC2136 chip.

The beneficial effect of technical solution of the present invention is:

Described tag read-write equipment device is used ARM7 processor, communications band has been used the free frequency range of 2.4G, the wireless data that real-time listening active electronic label sends, after processing, ARM7 produces by wired communication interface module, there is recognition speed fast, degree of accuracy is high, signal update is fast, and the feature of energy requirement of real time, can improve read write line range of management largely.

Embodiment

According to drawings and embodiments the present invention is described in further detail below.

As Figure 1-3, described tag read-write equipment device comprises ARM7 processor, and the 2.4G signal transmitting and receiving module, power module, wired communication interface module, the data-carrier store that are connected with ARM7 processor respectively;

Described power module comprises: AC/DC converter, DC/DC converter;

Described wired communication interface module comprises: the RS232 interface being connected with ARM7 processor respectively, 485 interfaces;

Described ARM7 processor adopting LPC2136 chip.

Read-and-write device, when starting, is first that ARM7 processor obtains configuration parameter from data-carrier store the inside, and 2.4G signaling module is carried out to the configuration of radio frequency parameter and the selection of wired communication interface; Then whether Real-Time Monitoring 2.4G signaling module and wired communication interface have data, according to Data Source and data content, carry out corresponding analyzing and processing, and result is sent in corresponding module, be can transfer by wired communication interface after the ID signal analysis and processing receiving on 2.4G signaling module, the read write line configuration parameter that wired communication interface receives can store in data-carrier store, and the active electronic label information that wired communication interface receives can be transmitted to active electronic label by 2.4G signaling module.

Above-mentioned tag read-write equipment device is used ARM7 processor, communications band has been used the free frequency range of 2.4G, the wireless data that real-time listening active electronic label sends, after ARM7 processes, by wired communication interface module, produce, have recognition speed fast, degree of accuracy is high, signal update is fast, the feature of energy requirement of real time, can improve largely read write line range of management, other two kinds of on-the-spot wired communication interfaces are optional, are convenient to on-the-spot construction and installation.
