Abstract
The invention discloses long-distance interactive multi-user intelligent LED screen equipment based on the GPRS. The equipment is composed of a GPRS module, a single chip microcomputer, an LED display screen, an image sensor, a voice record-replay chip, a relay circuit which is arranged around the LED display screen, and an infrared detection circuit. According to the equipment, characters and patterns of the LED display screen can be replaced in a remote mode through short messages or multimedia messages of a mobile phone via the GPRS network, and wireless control over electrical equipment around the display screen is further achieved; in addition, the equipment further has a multi-user hierarchical management mode, an independent control multi-screen mode and an unmanned autonomic screen closing mode, the utilization rate of the LED display screen is greatly improved, the LED display screen is made more economical, more energy can be saved, and therefore the LED display screen can be used as an information publicity tool in public places to be perfected and popularized.
Description
Technical field
This relates to information communication field, is specifically related to a kind of long-distance interactive multi-user intelligent LED screen equipment based on GPRS.
Background technology
Along with the universal of LED display and the reduction of cost, LED display has become a kind of important tool of public arena information propagating.Current realization mainly contains the method that the character pattern of LED display is changed:
(1) display screen to be connected with computer by serial ports and to realize changing.
(2) realize long-range change by wireless GPRS network, transmitting terminal needs the specific software on computer to edit transmission.
For the LED display utilizing wireless remote transmission information, use above method (2) also to there are some problems: 1) transmitting terminal need work on a computer platform, send address and be restricted, be difficult to realize portable change, property is low everywhere in real time.2) owing to realizing on computers, and need specific software for editing, fringe cost is too high.3) LED display can only realize single user mode, and display screen utilance is not high.4) GPRS module can only control single display screen, and GPRS module utilance is not high yet, has increased the weight of the cost of whole equipment.
Summary of the invention
In order to solve these problems that the LED display that utilizes transmitting information wirelessly at present exists, the invention provides a kind of long-distance interactive multi-user intelligent LED screen equipment based on GPRS.Its technical scheme is: this equipment is by GPRS module, single-chip microcomputer, LED display, image sensor, voice recording and playback ic, infrared detection circuit and be positioned at the relay circuit arranged around LED display and form; Above-mentioned single-chip microcomputer is connected with LED display, GPRS module, image sensor, voice recording and playback ic, relay circuit and infrared detection circuit respectively.
By two RS232 serial ports, LED display and GPRS module connect above-mentioned single-chip microcomputer respectively; Above-mentioned single-chip microcomputer is connected with voice recording and playback ic by spi bus; Above-mentioned single-chip microcomputer is connected with image sensor, infrared detection circuit, the relay circuit be arranged in around LED display respectively by I/O line.
Above-mentioned GPRS module is connected with user mobile phone, service provider's mobile phone wireless respectively.
Above-mentioned relay circuit connects power consumption equipment.
Above-mentioned power consumption equipment is color lamp, motor, music broadcast
Above-mentioned relay circuit is at least made up of six relays.
The invention has the beneficial effects as follows:
1. send multimedia message by mobile phone and change the writings and image information of LED display and the voice messaging of voice broadcast service in time, and simultaneously by realizing the control to around power consumption equipment (as color lamp, motor) to the control of relay.
2. obtain field data by image sensor, be then sent to by means of GPRS network and multimedia message mode and specify the mobile phone of SIM card number or PDA to realize remote monitoring.
3. realize multi-user's hierarchical management model, keeper has highest weight limit, first fixed each user can only show the information of a certain user in special time period.Oneself display information is revised by password authentification in the authority that user can distribute keeper.
4. independently can control the LED display screen information change of much 256.
5. have unmanned pass automatically screen pattern, when being in this pattern, unmanned through out-of-date within the scope of before screen ten meters, screen will close screen automatically, make display screen more energy-conservation.
Accompanying drawing explanation
Fig. 1 is circuit function module figure of the present invention.
In figure:
1. service provider's mobile phone, 2. user mobile phone, 3.GPRS module, 4. infrared sensor, 5. single-chip microcomputer, 6. relay circuit, 7. power consumption equipment, 8. image sensor, 9.LED display screen, 10. voice recording and playback ic
Embodiment
With reference to Fig. 1, the course of work describing equipment is as follows:
1. when GPRS module receives note, it sends information by serial ports to single-chip microcomputer, through the process of single-chip microcomputer, verifies that whether its password is correct according to different user.If password bad, information is deleted.If password is correct, then wants single-chip microcomputer to preserve information, then process.
2. keeper or user are by sending the communication number that note or multimedia message to GPRS module are specified, single-chip microcomputer is according to the form of note or multimedia message, first information is processed, the pictograph content being decomposed into control command information and will show, and control command information can be divided into, and Control, field image obtain, LED display display mode controls and speech chip control command.Then single-chip microcomputer is sent to LED display by Serial Port Line pictograph content, and controls the display mode of pictograph content on LED display according to display mode order.If there is speech chip control command, then judge whether to broadcast the content of short message according to this order, or change the content playing voice.If also have Control order, by realizing the control to peripheral equipment to the control of relay.
3. by described in 2 when keeper or user send field image obtain control command time, image sensor is started working, IMAQ is carried out to the situation at scene, then through the process of single-chip microcomputer, keeper or user is sent to by GPRS network in multimedia message mode by means of WTP, WSP, MMSE, udp protocol.
4., when opening the unmanned screen pattern of pass automatically, single-chip microcomputer carries out regular check to infrared sensor, if when can't detect signal in 10 seconds, screen will be closed automatically.
