The device can timely remind the drivers of adding cooling liquid to the cooling system of the engine to ensure the normal work of the cooling system, so that the engine can work in an appropriate temperature range, wear of the parts inside the engine is reduced and the working life of the engine is prolonged.
Description
Technical field
The utility model belongs to single-chip microcomputer comprehensive application technology field, relates to the device of automobile technical field, particularly a kind of safety instruction device of automobile cooling system.
Technical background
Along with the fast development of China's automobile industry, the recoverable amount of China's automobile increases by a fairly big margin, and nowadays automobile has become the main traffic tool of people's trip; Yet do not know how to maintain the people of automobile for those; The general maintenance of taking away of the car with oneself that all can be frequent, that will bring maintenance expenses, especially motor this part of costliness to them; If do not understand maintenance, must spend higher expense.When engine operation; The temperature of its combustion chambers burn can be up to 2500 ℃, and too high temperature will make the intensity of metallic material significantly descend, the also rotten or viscosity decline with the Yin Gaowen scaling loss of lubricant oil; This can cause the stuck or aggravation wearing and tearing of moving parts, therefore in addition appropriateness cooling of motor.Yet the cooling liquid of motor car engine generally is the driver rule of thumb comes to add cooling liquid to motor; The driver tends to forget to motor and adds cooling liquid in the using process; Thereby cause engine-cooling system work undesired; Make motor at high temperature work and can not get the cooling of appropriateness, aggravate the wearing and tearing of engine interior component the most at last, reduce the working life of motor.
Summary of the invention
To defective or deficiency that above-mentioned existing technology exists, the purpose of the utility model is, a kind of safety instruction device of automobile cooling system is provided; When motor need add cooling liquid; This device can in time remind the driver to add cooling liquid for the cooling system of motor, makes cooling system in proper working order, thereby lets motor under suitable temperature range, work; Reduce the wearing and tearing of engine interior component, make engine operational life longer.
In order to realize above-mentioned task, the utility model adopts following technological scheme to be achieved:
A kind of safety instruction device of automobile cooling system comprises storage battery, ignition switch and the water tank of automobile it is characterized in that level sensor is installed, and level sensor is connected with single-chip microcomputer in radiator, also is connected with phonetic alarm on the single-chip microcomputer; Level sensor, single-chip microcomputer and phonetic alarm provide power supply after passing through the ignition switch step-down by storage battery.
Other characteristics of the utility model are:
Said single-chip microcomputer adopts the AT89C52 single-chip microcomputer, and its signal that can gather level sensor output fast and accurately comes phonetic alarm is operated.
Described level sensor is selected HM21 throw-in type fluid level transmitter.
Described phonetic alarm is selected the PM5020 speech chip.
The safety instruction device of the automobile cooling system of the utility model; When the liquid level of compensation water is lower than operational height (" DI " line); Level sensor will be exported the low signal of water level to signal processing unit this moment; Then the phonetic alarm information that just can transmit according to single-chip microcomputer in time to driver's prompting that gives the alarm, lets the driver add cooling liquid to engine-cooling system fast well, can obtain when letting engine operation cooling off.So just can let the engine interior component reduce because the aggravation that the cooling system problem is brought is worn and torn, lubricant oil uses longer, and component are difficult for stuck, and motor working life will be longer, thereby reduce a large amount of maintenance expensess.In addition this device have easy to make, characteristics such as circuit is simple, and cost is low.

Fig. 2 is the circuit catenation principle figure of the utility model.
Fig. 3 is the workflow diagram of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment
With reference to Fig. 1; Present embodiment provides a kind of hardware configuration of safety instruction device of automobile cooling system, comprises storage battery, ignition switch and the water tank of automobile, and level sensor is installed in radiator; Level sensor is connected with single-chip microcomputer, also is connected with phonetic alarm on the single-chip microcomputer; Level sensor, single-chip microcomputer and phonetic alarm provide power supply after passing through the ignition switch step-down by storage battery.
In the present embodiment; Level sensor is selected HM21 throw-in type fluid level transmitter, is installed in the compensation bucket of engine-cooling system, and it utilizes the hydrostatics principle to measure water level and liquid level; It is a kind of important application of pressure transducer; The highly sensitive silicon pressure resistance photosensitive elements made from micromachining technology is the heart of liquid level sensor, and it is technological to be aided with the private cable of be with airway and special water-stop, has both guaranteed the water-stop of intrusive mood sensor; Make the reference pressure chamber identical again, thereby obtain measurement result and premium properties accurately with ambient pressure.
Single-chip microcomputer and phonetic alarm are installed on the instrument panel, and driver can in time be added cooling liquid to cooling system after hearing voice suggestion.
In the present embodiment, the AT89C52 single-chip microcomputer that single-chip microcomputer adopts Atmel company to produce, it comprises the 8-bit microprocessor of high-performance, low power consumption, flash read-only program memory that the sassafras repeatedly of 8k bytes is write and the Random Access Data storage of 256bytes.Information process unit mainly receives and handles the information that the level sensor collecting unit is transmitted, and handles back information to voice alerting unit output.
Phonetic alarm adopts Beijing core sound exhibition to open up the PM5020 speech chip that electronics technology Co., Ltd produces, the control signal after the processing that the reception information process unit that it can be real-time is exported, and send relevant voice through the loudspeaker that drive this unit and point out.
With reference to figure 2, because HM21 throw-in type fluid level transmitter operating voltage is at 12V～36V, and the voltage that storage battery can provide is just in this scope; So can directly give the power supply of HM21 throw-in type fluid level transmitter by storage battery; The k1 of PM5020 speech chip, k2, the P3.2 of 01 spoken AT89C52; P3.1, the P3.0 mouth links to each other.The PM5020 speech chip is controlled 0.5 watt of loudspeaker work in 8 Europe through SPI mouth control triode 8050.
With reference to figure 3: the workflow of the utility model is as follows, and when system powers on, after the program initialization, HM21 throw-in type fluid level transmitter begins to detect the water level of compensation water in the cooling system, and with the form output of detected water level information with aanalogvoltage.Since the voltage signal exported of HM21 throw-in type fluid level transmitter too a little less than; Single-chip microcomputer detect less than; So the analog voltage signal of HM21 throw-in type fluid level transmitter output is sent into the amplification rectification circuit of being made up of LM324, with this water level signal amplify 5 times and carry out shaping after send into the A/D mouth of single-chip microcomputer, carry out after analog digital changes; Send the signal after handling to the PM5020 speech chip, the voice suggestion of being correlated with then.
