Abstract
The system includes proxy workstation, broadcasting letter server, base station, and receiving terminal group. Proxy workstation is in use for recording letter information needed to display. Through Internet, proxy workstation sends the information to the broadcasting letter server. Through radio, telephone line, or Internet, the broadcasting letter server transfers letter information to base station. Through wireless mode, base station sends information of modulated signal to the receiving terminal. According to different contents received, receiving terminals are divided into some receiving terminal groups to carry out demodulation, bug testing, error correction, recovering the received content, and displaying letter information. The information of receiving terminal self can be fed back to base station. Base station sends the information to broadcasting letter server for further processing.
Description
Technical field
The present invention relates to a kind of text broadcast system, relate in particular to a kind of wire-less character broadcasting system and method.
Background technology
At present in places such as bus, railway station, square, commercial building, crossings, be extensive use of billboard or the billboard of LED display as scrolling information, call out the stops, advertisement and show traffic information etc., but this LED display displaying contents relative fixed, change displaying contents, the needs that have are regularly by computer input or update content; What have need link to each other with computer, and displaying contents is controlled in real time.That the method for these text broadcasts can not realize is long-range, display message, and identical information quickly and easily will repeat to be input to each needs the text broadcast system, has wasted a large amount of manpower and materials.
The patent No. is 03231417.5, and name is called " a kind of vehicle LED display screen with the IC-card input information " and has used a kind of IC-card mode input information, but this method needs pre-edit that the IC-card of different content is set, and the real-time of display message is not strong.
The patent No. is 01223305.6, and name is called the mode that " wireless transmission LED display " used wireless transmission, and is little but this mode transmits scope, generally will closely just can receive wireless signal, and this just limits the scope of application of this method.

Embodiment
Below in conjunction with specific embodiment the present invention is described in further detail:
As shown in Figure 1, the present invention includes agent station 1, broadcasting text service device 2, base station 3, receiving terminal group 4.
Wherein agent station 1 is used for the Word message that typing need show, and this information is sent to broadcasting text service device 2 by the internet.
Broadcasting text service device 2 sends Word message to base station 3 by wireless, telephone wire or internet.
Receiving terminal 5 is divided into some receiving terminal groups 5 according to the received content difference, each receiving terminal group 4 comprises some receiving terminals 5, carry out demodulation, debugging, error correction, recovery by the aerial receiver (not shown), Word message is shown, also receiving terminal 5 self-informations can be fed back to base station 3, the base station sends to this information broadcasting text service device 2 again and handles.
But entry information on agent station 1, the information of institute's typing is recorded as one with one, and every record needs to limit number of words, the number of words that limits is specified by management work site server (not shown) is unified, and record format can be " record number, work station numbering; operator's numbering, receiving terminal numbering, date; time, priority, duration; effective time, control word, message length; information, check word ".
Native system adopts client/server configuration, agent station 1 is a client computer, broadcasting text service device 2 is a server, after the network address of input broadcasting text service device 2 on the agent station 1, but input username and password entrance management interface, at this moment can import the information that is used to show, operation such as also can inquire about former record, statistical work amount, carry out that mistake is recalled.
Broadcasting text service device 2 receives the information that agent station 1 sends, and after verifying, will have the information of problem (as errors in text) to return former agent station 1, is sent to each base station 3 with examining errorless information.Broadcasting text service device 2 also comprises the charge system (not shown), to public welfare information for free in the system, as weather forecast, real time temperature and humidity, current time etc.; Copy was chargeed by the scope and the duration of broadcasting.
Broadcasting text service device 2 can connect mode such as internet by telephone line modulator-demodulator, Radio Link, netting twine and be connected to base station 3.The operational factor of each base station 3 is presented on the (not shown) of office terminal, for example indexs such as the temperature of Fa She standing-wave ratio, voltage, electric current and base station, humidity.
As shown in Figure 2, base station 3 comprises interface 11, processor 12, FSK modulator 13, exciting unit 14, power amplifier unit 15, air feedback unit 16, synchronizer 17 (during many base stations), detecting unit 18.
After base station 3 received the information of broadcasting text service device 2 by interface 11, treated device 12 bufferings, FSK modulators modulate 13, exciting unit 14, power amplifier unit 15, air feedback unit 16 were wirelessly sent to receiving terminal 5.When many base stations, need to use synchronizer 17 to receive 12 pairs of information of processor and carry out synchronously.Detecting unit 18 connection processing devices 12, indexs such as the temperature of standing-wave ratio, voltage, electric current and the base station of responsible detection emission, humidity.
Under the situation of single base station, the data behind the buffer memory can directly be launched; Under the situation of many base stations, the data behind the buffer memory can be carried out the Millisecond time-delay, delay time at most 1 second.
When base station 3 no information can be sent out, base station 3 sent empty frame, and only provide frame synchronization for receiving terminal 5 this moment.
As shown in Figure 3, receiving terminal 5 comprises central processing unit 21, wireless frequency modulation receiver 22, radio frequency modulatng transmitter 23, modulator-demodulator 24, memory 25, operation keyboard 26, LED display 27, printer 28, loud speaker 29.
Receiving terminal 5 emissions are synchronous with the even frame of base station 3, receiving terminal 5 just can send after receiving and sending acknowledgement frame, 16 bit information codifieds wherein, for example 0X0000 can represent station 1 in the information frame, 0X0001 can represent station 2 or the like, on behalf of car, 0X0000 fault is arranged in the control frame, 0X0001 representative departures or the like.
Receiving terminal 5 emission information should be at random, and in the range of receiving of base station 3, randomness is set with the delay parameter of departures, and each needs the receiving terminal 5 of transmitting site all should to avoid receiving terminal 5 to launch simultaneously and produce collision at bus stop announcement device (not shown) starting back random delay.
Issue central processing unit 21 error detections, error correction after sending into modulator-demodulator 24 modulation after the wireless modulated signals of receiving terminal 5 by wireless frequency modulation receiver 22 reception base stations 3, record that can't error correction is lost, with the error-free record roll display received on light-emitting diode display 27, every records local numbering, and being interested in can be by number selective printing.
When receiving terminal 5 is bus, can selects the name of station storehouse that is stored on the memory 25 for use, and when showing name of station, the base station be beamed back at destination or traffic coverage.
When receiving terminal 5 is station board, can shows the traffic coverage of vehicle, as be presented at certain interval car is arranged.
Specific embodiment of the present invention elaborates summary of the invention.For persons skilled in the art, any conspicuous change of under the prerequisite that does not deviate from the principle of the invention it being done all constitutes the infringement to patent of the present invention, with corresponding legal responsibilities.
