The utility model content

The purpose of this utility model just is to provide in order to address the above problem a kind of display controller of the dynamic display system based on REID.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The display controller of the dynamic display system based on REID described in the utility model comprises central processing unit, storer, power supply, RFID label communicating circuit and display output circuit, wherein:

Central processing unit is as computing and respectively corresponding connection with other parts of control core;

Storer is used for the data message that storage needs demonstration;

Power supply is used to central processing unit that electric energy is provided;

RFID label communicating circuit is used for the RFID label is carried out Card read/write;

Display output circuit is used for to display screen output display signal.

The beneficial effects of the utility model are:

Carry out obtaining and exporting of e-advertising content-data information by the utility model, can store take the RFID label as information intermediate carrier, realize and the radio frequency communication of ad content layout device, improved the efficient that content is changed, further promoted the development of e-advertising industry.

Description of drawings

Fig. 1 is the system chart that comprises the dynamic display system of display controller described in the utility model;

Fig. 2 is the structured flowchart of display controller described in the utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, the dynamic display system that comprises display controller described in the utility model comprises display screen, RFID label, identification radio-frequency card, content arrangement device, display controller and background server, wherein, only have between display controller and the display screen and adopt wire communication, all adopt wireless telecommunications between other parts.Display screen, RFID label and display controller integrate, and jointly form the wireless telecommunications display.Generally speaking, the wireless telecommunications display is exactly a display screen from appearance, and display controller is installed in the housing of display screen, and the RFID label can be mounted on the display screen housing.

As shown in Figure 2, display controller described in the utility model comprises central processing unit, storer, power supply, RFID label communicating circuit and display output circuit, wherein:

Central processing unit is as computing and respectively corresponding connection with other parts of control core;

Storer is used for the data message that storage needs demonstration;

Power supply is used to central processing unit that electric energy is provided;

RFID label communicating circuit is used for the RFID label is carried out Card read/write;

Display output circuit is used for to display screen output display signal.

Above-mentioned each parts are the conventional components in the existing every profession and trade.

In conjunction with Fig. 1 and Fig. 2, the principle of work of display controller described in the utility model is as follows:

Central processing unit reads or rewrites the RFID label information of carrying out by RFID label communicating circuit, and determines whether the content in the storer of RFID label is write in the storer of display controller according to the memory state of RFID label; Central processing unit, is sent the content of the storer of display controller into display screen and is shown to display screen output display signal by display output circuit.

In conjunction with Fig. 1, principle of work and the course of work of dynamic display system described in the utility model are as follows:

The storage area of RFID label is divided into state storage space and content storage space, the status information of the storage of state storage space " newly ", " old ", " locking " three kinds of states, and the storage of content storage space needs the data message of demonstration.When rewriting label substance, operating personnel are at first at content arrangement device brush identification radio-frequency card, the content arrangement device reads card number, be the operating personnel's information of obtaining the information of preserving in the content arrangement device from background server or this locality, judging has lack of competence to use the content arrangement device, then, seen that lack of competence rewrites displaying contents read the RFID label ID number, and background server or this locality be that the information of preserving in the content arrangement device is done Secondary Match.After checking was passed through, the content arrangement device read first the status information of RFID label, if be " locking ", the expression display controller is just from RFID label read data information, and can not rewrite the data message of RFID label this moment, needs to wait for; If the status information of RFID label is " old ", expression can be upgraded the data message of RFID label, at this moment, the content arrangement device at first is rewritten as " locking " with the status information of RFID label, and expression display controller this moment can't be from RFID label read data information; After rewriting was finished, the content arrangement device was rewritten as " newly " with the status information of RFID label.During system initialization, the status information of RFID label is " newly ", during first the demonstration, display controller is at first judged the status information of RFID label, if be " newly ", then at first change the status information of RFID label into " locking ", the denoting contents composer can not be write data message to the RFID label this moment.Display controller reads first the status information of RFID label, if be " newly ", then read data message in the RFID label and put into the storer of display controller, status information with the RFID label is rewritten as " old " subsequently, in the demonstration afterwards, display controller at first reads the status information of RFID label, if be " locking ", then denoting contents just upgrades, and waits for; If be " newly ", then denoting contents upgrades, need to again read the data message of RFID label and put into storer; If be " old ", then directly show the content in the storer of display controller.

Claims (1)
