Description

Vehicle wiper water tank water level displaying alarm
Technical field
The utility model relates to a kind of warning device, specifically is a kind of vehicle wiper water tank water level displaying alarm based on ultrasonic transduter.
Background technology
Vehicle wiper is the device of automobile indispensability, and the water of windshield wiper water tank is sprayed on and cleans glass on the Windshield in the process of use.In use the situation that water tank does not have water suddenly can appear, especially on rainy day, when take up in the vehicle ' of the place ahead the mud that comes spread the rear automobile before during windshield, if the wiper water tank does not have water suddenly, the preceding windshield of front vehicle can't be cleaned out, have a strong impact on the front vehicle driver vision, very easily cause traffic accident.And the high-end vehicle that has only the minority brand at present is furnished with integrated wiper water storage annunciator.Under this background, the utility model has designed a cover vehicle wiper water tank water level displaying alarm.
The utility model content
The purpose of this utility model is, a kind of intelligent tap water leak-proof device is provided, and being used for monitoring, whether to belong to the normal life water still be improper leaking, and in time solve seepy question.To achieve these goals, the technical solution adopted in the utility model is:
Vehicle wiper water tank water level displaying alarm comprises water tank, microcontroller (Micro Control Unit is to call microcontroller MCU in the following text), ultrasonic liquid level sensor, warning circuit and the power supply of vehicle wiper; Wherein, power supply is electrically connected with MCU microcontroller, ultrasonic liquid level sensor, warning circuit respectively, and the MCU microcontroller is electrically connected with ultrasonic liquid level sensor, warning circuit respectively; The transmitting terminal probe of described ultrasonic liquid level sensor and receiving end probe are installed in the top of water tank respectively.
Optimally, also comprise LCD display, described LCD display is electrically connected with MCU microcontroller, power supply respectively.
Optimally, described warning circuit comprises buzzer phone.
The utility model adopts the excusing from death wave sensor to measure the water level of water tank, ultrasonic transduter comprises transmitting terminal and two probes of receiving end, be installed in the top of vehicle wiper water tank respectively, send control signal by microcontroller MCU and give excusing from death wave sensor transmitting terminal probe, excusing from death wave sensor transmitting terminal probe sends the ultrasonic pulse signal that frequency is 40HZ, after liquid levels reflects in water tank, receive the ultrasonic pulse signal that reflects by excusing from death wave sensor receiving end probe, and send this impulse singla to microcontroller MCU, calculate current flow container in liquid level according to super sonic from time and the corresponding testing algorithm that is transmitted into reflection process by microcontroller MCU.The distance value of supposing transmitting terminal and receiving end probe distance liquid level is S, ultrasonic propagation velocity is velocity of sound C, spontaneous emission end transmitter pulse signal is T to the time that the receiving end probe receives impulse singla, and the relation between them can be formulated so: S=C*T/2.The bottom-to-top-height of water tank is deducted S, just can draw the present liquid level value of water tank.
Microcontroller MCU delivers to LCD display with liquid level numerical value and shows.By microcontroller MCU designated water level limit, when the liquid level value of reaching the limit of, drive warning circuit by microcontroller MCU and realize voice suggestion.
Other features and advantages of the utility model will be set forth in the following description, and, partly from specification sheets, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in the specification sheets of being write, claims and accompanying drawing.
