Accompanying drawing explanation

Fig. 1 is the circuit diagram of the intelligent LED traffic allowance based on BLE4.0 human-computer exchange.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, a kind of intelligent LED traffic allowance based on BLE4.0 human-computer exchange, comprise mobile phone A PP module, the master controller being with BLE, LED dot matrix display screen, vehicle detection subsystem, front vehicle detection system and power supply power consumption subsystem, the master controller of described mobile phone A PP model calling band BLE, master controller with BLE also connects vehicle detection subsystem, front vehicle detection system and dot matrix sub-controller respectively, dot matrix sub-controller also connects FLASH and LED dot matrix display screen respectively, and vehicle detection subsystem also connects power supply power consumption subsystem.

Front vehicle detection system comprises whistle signal module, two glitch module and headlight signaling module.Vehicle detection subsystem comprised bank signaling module, braking strength signaling module and transport condition signaling module.Power supply power consumption subsystem is chargeable lithium cell power supply.

Principle of work of the present utility model is: (1) mobile phone A PP module: micro-letter client platform, add bluetooth at micro-letter kernel and drive protocol stack, with BLE Master Communications subsystem radio communication, micro-letter client platform can send display command or direct editing Chinese character sentence, picture symbol pictures such as (such as smiling face, face of crying) waiting a moment, animation or phonetic entry Chinese character sentence and be transferred to BLE control device subsystem through Bluetooth channels.

(2) be with the master controller of BLE: BLE master controller upwards with handset Wechat client through Bluetooth communication, based on the communication of AT command protocols or transmission Chinese character sentence, picture, moving picture coding frame data bag, communicate with LED screen controller custom protocol downwards, master control by the instruction of micro-letter client or coded frame data bag through decodes transport to LED dot matrix screen processor, and then send LED display to show through dot matrix screen algorithm process through universal serial bus decoding data.

(3) LED dot matrix display screen: FLASH stores and LED driving display.The various sensors receiving APP content (instruction, Chinese character sentence, picture, animation etc.) or master controller when master controller detect the storing information that Automatically invoked is corresponding after various signal, are transferred to the display of LED dot matrix screen.The content that cell-phone customer terminal sends is presented on LED dot matrix screen, and the signal that detects of vehicle and front vehicle call static store to FLASH content (as Chinese character, picture, animation), or compile again through the data of BLE decoding and be transferred to arm processor.
