Description
Technical field:
The present invention relates to the detection system technical field, relate in particular to a kind of static magnetic field fluxgate parking stall detection system.
Background technology:
Along with the transformation of growth in the living standard and life style, it is in the life that automobile has got into ordinary populace, the large-scale also supporting thereupon generation in garage; In most cases, it is that managerial personnel carry out complicate statistics that the parking stall in garage takies situation, the operating position that the person of parking can not the exact grasp parking stall; Many times; After the person of parking gets into the garage, find empty parking stall to need the expensive time, find that sometimes the parking stall is fully parked with in the garage; Need roll the garage away from and need look for other to park a little, the delay great amount of time.
Existing parking stall detector generally is through hyperacoustic principle, and ultrasonic unit is installed at the top, parking stall, judges through the ultrasonic reflections mistiming whether the parking stall has car.But there is following shortcoming in existing parking stall detector: 1, need the power supply of 220v alternating current or DC circuit, the construction wiring is inconvenient, and power consumption is big, the waste electric energy; 2, structure is non-watertight, and the open air can't be used, and uses inconvenient.
Summary of the invention:
The object of the invention is exactly the deficiency that exists to prior art and provide a kind of variation that utilizes magnetic field to come unloading lot detection to take the static magnetic field fluxgate parking stall detection system of situation, easy for installation, saves energy.
To achieve these goals, the technical scheme of the present invention's employing is:
Static magnetic field fluxgate parking stall detection system; The amplification module that includes coil that permanent magnet, induction magnetic field of permanent magnet change, coil current signal is amplified, control module, the supplying cell of supplying power to the signal projector of terminal server transmission information, for each components and parts; The input end connecting coil of amplification module; The input end of the output terminal link control module of amplification module, the output terminal of signal projector link control module, supplying cell is electrically connected with control module.
Said control module is a single chip control module.
Said signal projector is a radiofrequency launcher.
Said supplying cell is the inferior battery of lithium.
The present invention also includes parking stall situation pilot lamp, and parking stall situation pilot lamp is connected with the output terminal of control module.
Beneficial effect of the present invention is: the present invention includes permanent magnet, coil, amplification module, control module, signal projector, supplying cell, the input end connecting coil of amplification module, the input end of the output terminal link control module of amplification module; The output terminal of signal projector link control module, supplying cell is electrically connected with control module, the B/H curve that the present invention utilizes permanent magnet and coil to produce; Under the situation that does not have car above the detection system, the B/H curve of static magnetic field has an approaching fixed value, when car is above detection system; Because cutting magnetic line; Cause magnetic field to change, the B/H linear relationship changes, and the variation in magnetic field makes coil produce current signal; Current signal amplifies through amplification module and is transferred to control module and analyzes and judge the parking stall situation; And through signal projector with information transmission to terminal server, so the keeper can understand the parking condition of parking stall, whole garage at any time through terminal server, guiding vehicle is parked; Information is accurate, and is convenient and swift; And the present invention utilizes permanent magnet and coil to survey, and is low in energy consumption, only need with the supplying cell power supply, and energy-conserving and environment-protective, simple in structure, easy to install and use, water-tight can outdoor use.
Description of drawings:
Fig. 1 is a functional-block diagram of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described; See shown in Figure 1; Static magnetic field fluxgate parking stall detection system; The amplification module 3 that includes the coil 2 of permanent magnet 1, induction permanent magnet 1 changes of magnetic field, coil 2 current signals are amplified, control module 4, the supplying cell 6 of supplying power to the signal projector 5 of terminal server 8 transmission information, for each components and parts, the input end connecting coil 2 of amplification module 3, the input end of the output terminal link control module 4 of amplification module 3; The output terminal of signal projector 5 link control modules 4, supplying cell 6 is electrically connected with control module 4.
Control module 4 is a single chip control module, and control is convenient, stable performance, moderate cost.Signal projector 5 is radiofrequency launcher, and is simple in structure, dependable performance.Supplying cell 6 is the inferior battery of lithium, and power-on time is long.
The present invention can also be provided with parking stall situation pilot lamp 7, and parking stall situation pilot lamp 7 is connected with the output terminal of control module 4, shows whether corresponding parking stall has car, and the person that conveniently do not park selects the parking stall.
Principle of work of the present invention is: the present invention utilizes linear relationship, the state of saturation of the B/H curve that permanent magnet 1 and coil 2 produce, the variation of slope to come unloading lot detection.Under the situation that does not have car above the detection system, the B/H curve of static magnetic field has an approaching fixed value, when car is above detection system; Because cutting magnetic line causes magnetic field to change, the B/H linear relationship changes; The variation in magnetic field makes coil 2 produce current signals, and current signal amplifies through amplification module 3 and is transferred to control module 4 and analyzes and judge the parking stall situation, and through signal projector 5 with information transmission to terminal server 8; Therefore the keeper can understand the parking condition of parking stall, whole garage at any time through terminal server 8; Guiding vehicle is parked, and information is accurate, and is convenient and swift.
And the present invention utilizes the variation in the magnetic field of permanent magnet 1 and coil 2 to come unloading lot detection to take situation, and is low in energy consumption, only needs with supplying cell 6 power supplies; Energy-conserving and environment-protective, simple in structure, volume is little; Easy to install and use, can be installed in ground, all components and parts can be encapsulated in the housing; Water-tight can outdoor use.
In sum, and the present invention is reasonable in design, easy to process, cheap for manufacturing cost, meets environmental protection standard, the while energy savings, and be easy to recycle, be fit to be applied to places such as garage.
Certainly, the above only is preferred embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, characteristic and principle change or modify, includes in patent claim of the present invention.
