Abstract
An electronic north finder consists of a magnetic sensor, a signal amplifier, a microprocessor, a decoder, a revolving lamp panel, an indicator light, and a power supply. An output signal terminal of the magnetic sensor is connected with a signal input terminal of the signal amplifier. A signal output terminal of the signal amplifier is connected with a data input terminal of the microprocessor. After the magnetic sensor collects magnetic field signal from all directions, the magnetic field signal is transmitted to the signal amplifier for further amplification; the signal amplifier transmits the amplified signal to the microprocessor for procedure operation; the microprocessor inputs the operation result into the decoder for decoding; decoded signal is accessed to the a display circuit to drive the indicator light arranged in the north of the front to give out light for display. By adopting the utility model, the indicating accuracy is high; the indication reaction rate is high; the indication model is novel, and the utility model can be used all day long.
Description
Technical field
The utility model relates to a kind of device of direction indication, and specifically a kind of electronics refers to the north meter.
Background technology
Existing indicating device mainly is divided into two kinds: a kind of is pointer-type, mainly is according to pointer induced field stress difference, and the rotation by mechanical part is presented on a certain index dial.A kind of digital, it will sense magnetic field stress as signal, show to reach the purpose of direction indication by electronic console.Because above indicating device is with low content of technology, has the precision deficiency, the slow and narrow shortcoming of usable range of reaction.
The utility model content
In order to provide a kind of pointing accuracy height, Indicator Reaction speed is fast, indicating mode is novel and all-weather is easy to use electronics to refer to the north meter.
The technical scheme that the utility model adopted is: electronics refers to the north meter, it is made up of magnetometric sensor, signal amplifier, microprocessor, demoder, rotation lamp panel, pilot lamp, power supply, microprocessor Design has the control computing circuit, electronics refers to the mode travel direction indication that the north meter is lighted with the light of pilot lamp or glimmered, the edge of rotation lamp panel is evenly distributed a plurality of pilot lamp, and the rotation lamp panel can be by clockwise or rotation counterclockwise.
The output signal end of magnetometric sensor links to each other with the signal amplifier signal input part, the signal amplifier signal output part links to each other with the data input pin of microprocessor, after magnetometric sensor is collected each orientation field signal, field signal is sent to signal amplifier further to be amplified, signal amplifier imports amplifying signal into microprocessor again and carries out sequential operation, microprocessor is input to operation result in the demoder and decodes, decoded signal inserts display circuit driving the luminous demonstration of pilot lamp of position, the positive north, thereby reaches the purpose of direction indication.
The beneficial effects of the utility model are, the pointing accuracy height, and Indicator Reaction speed is fast, the novel and all-weather effect easy to use of indicating mode.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.Wherein:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model display circuit figure;
Fig. 3 is the control computing circuit figure of microprocessor of the present utility model;
1. magnetometric sensors among Fig. 1,2. signal amplifier, 3. microprocessor, 4. demoder, 5. rotation lamp panel, 6. pilot lamp, 7. power supply.
Embodiment
The utility model is as shown in Figure 1: after magnetometric sensor 1 is collected each orientation field signal, field signal is sent to signal amplifier 2 further to be amplified, signal amplifier 2 imports amplifying signal into microprocessor 3 li again, microprocessor 3 is put into control computing circuit Fig. 3 with signal and is carried out sequential operation, microprocessor 3 is input to operation result in the demoder 4 and decodes, decoded signal inserts among display circuit Fig. 2 driving the pilot lamp 6 luminous demonstrations of position, the positive north, thereby reaches the purpose of direction indication fast and accurately.
