Abstract
The utility model relates to an electric automobile pedestrian warns system belongs to the electric automobile field, the utility model discloses a controller and loudspeaker subassembly, controller include singlechip, voice circuit, power amplification circuit and power amplifier switch, insert the loudspeaker subassembly after singlechip, voice circuit and power amplification circuit connect according to the order, and singlechip and power amplification circuit are connected to power amplifier switch's both ends. The utility model discloses a singlechip carries out analytical calculation to the pulse signal that car VCU (vehicle the control unit ) sent, judges current state that gos forward, backs a car of vehicle and speed per hour, according to various states, sends the sound of different frequency through loudspeaker, and when the vehicle was in within 0-40kmh of low -speed state, the system can segment according to interval of every 5kmh, sends the sound that the frequency rose gradually to reach the mesh of reminding the pedestrian.
Description
Technical field
The utility model belongs to electronlmobil field, particularly relates to a kind of electronlmobil pedestrian caution system.
Background technology
Along with the anxiety of world energy sources and increasingly sharpening of pollution, energy-conserving and environment-protective are more and more subject to people's attention, electronlmobil arises at the historic moment in such a case, low energy consumption, free of contamination advantage, it is made to be developed rapidly and to popularize, but due to electronlmobil travel under lower-speed state time, almost without any sound, will make like this special population such as some eyesights or person hard of hearing, the elderly, children electronlmobil close to time be difficult to recognize danger, just easily cause traffic accident.
Utility model content
Goal of the invention of the present utility model is to solve an above-mentioned difficult problem, proposes a kind of electronlmobil pedestrian caution system.
A kind of electronlmobil pedestrian of the utility model caution system comprises controller and horn assembly, controller comprises micro controller system, sound circuit, power amplification circuit and amplifier power supply switch, access horn assembly after micro controller system, sound circuit are connected in order with power amplification circuit, the two ends of amplifier power supply switch connect micro controller system and power amplification circuit.
Micro controller system adopts STM8S105C6T6 chip.
Sound circuit adopts NV080C chip.
Horn assembly adopts external magnetic type loudspeaker.
The utility model beneficial effect is as follows:
A kind of electronlmobil pedestrian caution system that the utility model proposes carries out analytical calculation by micro controller system to the impulse singla that automobile VCU (control unit for vehicle) sends, judge the current advance of vehicle, the state of reversing and speed per hour, according to various state, the sound of different frequency is sent by loudspeaker, when vehicle is within lower-speed state 0 ~ 40km/h, system can be segmented according to every 5km/h interval, send the sound that frequency raises gradually, thus reach the object of reminding pedestrian.
Accompanying drawing explanation
Fig. 1 is entire system block diagram.
Fig. 2 is sound circuit circuit diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described:
As shown in Figure 1, a kind of electronlmobil pedestrian of the utility model caution system comprises controller 1 and horn assembly 2, controller 1 comprises micro controller system 101, sound circuit 102, power amplification circuit 103 and amplifier power supply switch 104, access horn assembly 2 after micro controller system 101, sound circuit 102 and power amplification circuit 103 are connected in order, the two ends of amplifier power supply switch 104 connect micro controller system 101 and power 103 amplifying circuit.
Micro controller system 101 is the core component of whole system, be responsible for the control part of whole system, micro controller system 101 is by receiving and analyzing the impulse singla sent from automobile VCU (control unit for vehicle), corresponding instruction be sent to sound circuit 102 after judging, the STM8S105C6T6 chip adopted is automobile application layer micro controller system, this chip supports that low-power consumption mode runs, and has multiple communication interface, saves time and the cost of circuit exploitation.
Acting as of sound circuit 102 receives the instruction that sends of micro controller system 101, exports corresponding voice signal, employing be the core of NV080C speech chip as whole circuit, it is low that this chip has cost, stable performance, controls the features such as convenient.
The electric signal act as sound circuit 102 sends of power amplification circuit 103 amplifies, and horn assembly 2 can be driven to sound.
The signal acting as reception micro controller system 101 of amplifier power supply switch 104, thus control the opening and closing of power amplification circuit 103.
Horn assembly 2 is mouths of whole system, sends the sound of certain frequency, and to remind Pedestrians and vehicles to close on, what horn assembly 2 adopted is external magnetic type loudspeaker, relative to internal magnetization loudspeaker, has cost low, tonequality height and sensitivity advantages of higher.
As shown in Figure 2, 1 pin of NV080C speech chip is busy signal mouth, power end is accessed after connecting a LED, when system is in busy, LED can light, prompt system be in busy in, chip 3 pin is serial data input end, be connected to the mouth of micro controller system 101, be used for receiving the instruction that sends of micro controller system 101, chip 4 pin is power amplifier mouth, be connected to power amplification circuit 103, ground connection after a connection pull down resistor R1 in addition, chip 5 pin is also power amplifier mouth, power supply is accessed after being connected with 6 pin power ends, 7 pin are ground terminal, a filter capacitor C is accessed between 6 pin and 7 pin.
The above; it is only preferred embodiment of the present utility model; not do any type of restriction to the utility model, those skilled in the art utilizes the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drops in protection domain of the present utility model.
