Abstract
A water level detecting system for a water tank of an automobile is characterized in that the water level detecting system mainly uses a capacitive liquid level limiting sensor (1) as a key instrument; a signal converting device is an amplifying circuit (2); a switch control device and a display device are realized by an electromagnetic relay (3) and an LED (light-emitting diode) display lamp (4); the capacitive liquid level limiting sensor (1) is positioned in the middle of the top part of a spare water tank of the automobile; the amplifying circuit (2) is realized by an integrated circuit board; and the LED display lamp (4) is arranged at an instrument panel part of an automobile. The water level detecting system has the advantages of simple structure, reliability and the like.
Description
Technical field
The utility model relates to the vehicle safety detection range, specifically is the application of a kind of water-level instrumentation on automobile.
Background technology
At the reality that domestic automobile detects, utilize various senser elements to monitor the working condition of each parts of automobile in real time and feed back to corresponding display instrument and realize detecting.Automobile leaks because of thump or car accident can cause unavoidably that water tank breaks in the process of moving, or the air-dry effect in the external world can make water tank liquid coolant position that the decline of not expecting takes place again during because of the work of heating radiator at ordinary times, and the minimizing of water tank liquid coolant is if the attention that does not cause the driver is then can be because of the water tank liquid coolant not enough or seriously not lack the serious accident of driving that causes.
Summary of the invention
The utility model is to address the above problem, monitoring liquid level when providing a kind of water tank to be equipped with the water tank level detector just to have started for engine, and provide the testing result signal in time in water tank, to add liquid coolant (being generally water) to the driver to remind the driver by pilot lamp.Specific embodiments is as follows:
A kind of radiator water level detecting system, comprise Level monitor, chromacoder, switch controlling device and display device, the used key instrument of described water level monitoring system is capacitance type liquid level limit sensors (1), described chromacoder is an amplifying circuit (2), and described switch controlling device and display device are realized by an electromagnetic relay (3) and LED display lamp (4); Capacitance type liquid level limit sensors (1) is positioned at automobile and is equipped with the tank top centre position, and amplifying circuit (2) is realized with surface-mounted integrated circuit, LED display lamp (4) is installed on the automobile instrument disc portion.
Major technique advantage of the present utility model:
(1), water tank is equipped with and adds the liquid level limit sensors in the water tank, when just starting, automobile whether needs to add water with prompting for the driver by the bright dark signal of pilot lamp, save the driver and needed to detect the trouble whether water tank needs to add water frequently, or jolting of having avoided causing because of pavement behavior is relatively poor and water tank that mishap causes reveal cistern water level descended, and the driver forgets that once in a while the automobile that adds water and cause damages the generation of incident even;
(2), pilot lamp is arranged to normal bright form (pilot lamp is bright when not needing to add water) and has been avoided incuring loss through delay the serious consequence that adds water and cause because of pilot lamp damages the driver's erroneous judgement cause.
Description of drawings
Fig. 1 is the synoptic diagram of the Circuits System of cistern water level detection system described in the utility model;
Fig. 2 is the program synoptic diagram of cistern water level detection system;
Fig. 3 is a capacitance type liquid level limit sensors synoptic diagram.
Embodiment
Among Fig. 11, water tank is equipped with the cistern water level sensor; 2, amplifying circuit; 3, electromagnetic relay; 4, LED display lamp.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
As shown in Figure 1, cistern water level detection system described in the utility model comprises water level monitoring system capacitance type liquid level stop 1, chromacoder amplifying circuit 2, switch controlling device relay 3 and display device LED display lamp 4.Described capacitance type liquid level stop inserts below the water tank level, and the variation of water level causes the change of electric capacity specific inductive capacity, and capacitive transducer then is converted into switching value with the change of this parameter, promptly exports high-low level.Amplifying circuit and capacitive transducer join, and the level signal of sensor output is amplified, and give the electromagnetic relay that joins with it, and the relay switch machine is control pilot lamp light on and off water level switch.Should require to set the water tank normal water level according to reality on the capacitance type liquid level limit sensors earlier before using, when water level sensor output high level signal when setting value is above, make relay contact closure after amplifying circuit amplifies, pilot lamp keeps bright state; When liquid level drops to setting value sensor output low level signal when following, after amplifying, amplifying circuit makes the relay contact disconnection, and pilot lamp goes out.
Described capacitance type liquid level limit sensors manufacturing accuracy requires can realize more accurate measurement than higher, to improve the precision that vehicle safety detects.Under the essential condition of utility model, capacitance level transducer can be selected and transforms according to the height that is equipped with water tank during actual the use, but these are changed all within the claim protection domain under the utility model.The liquid level limit sensors must be fixedly installed in the top cover position of water tank fully during installation and be positioned at the centre position, with avoid because of road conditions jolt that the water level automatic lifting that causes causes than mistake.
Claims (1)
1. radiator water level detecting system, comprise Level monitor, chromacoder, switch controlling device and display device, it is characterized in that: the used key instrument of described water level monitoring system is capacitance type liquid level limit sensors (1), described chromacoder is an amplifying circuit (2), and described switch controlling device and display device are realized by an electromagnetic relay (3) and LED display lamp (4); Capacitance type liquid level limit sensors (1) is positioned at automobile and is equipped with the tank top centre position, and amplifying circuit (2) is realized with surface-mounted integrated circuit, LED display lamp (4) is installed on the automobile instrument disc portion.
