Abstract
The utility model provides an aviation altimeter report height indicating device, includes communication interface circuit, sets up at the singlechip of interface circuit output and sets up the display circuit at the singlechip output, and its technical essential is: the communication interface circuit comprises a communication interface with the coding altimeter and a communication interface circuit with the precision altimeter, and the display circuit comprises a height indication and coding state LED lamp indication part; the communication interface comprises two communication interfaces of a coding altimeter and a precision altimeter and is simultaneously connected to the singlechip. The problems of inconvenient non-uniform operation, low detection speed, low efficiency and the like of the equipment of the existing device are solved.
Description
Technical Field
The utility model relates to a check out test set field, the indicating device of aviation code altimeter and accurate altimeter report height specifically says so can accept the signal of telecommunication that comes from code altimeter or accurate altimeter and pass back to convert the signal into and correspond the altitude value and indicate, and detect code altimeter and accurate altimeter report altitude function.
Background
At present, the known report signal method for detecting the coded altimeter is to connect the returned signal to the indicator light, read the returned altitude code by turning on and off the indicator light, and then look up the table for comparison. The method has the disadvantages of complex operation, easy error of manual table look-up operation, slow detection speed and low efficiency. The known precision altimeter report height detection is carried out by using an improved GCY-1A high-precision comprehensive tester which is produced by matching with the Taihang instrument factory, the tester is not suitable for a coded altimeter, and the original GCG-1 high-precision comprehensive tester does not have the function of detecting the report height. Therefore, when different altimeters are maintained and detected, a plurality of different devices are connected and operated, and the operation is inconvenient.
SUMMERY OF THE UTILITY MODEL
The equipment for overcoming current device is not unified the operation inconvenient, and detection speed is slow, the inefficiency scheduling problem, the utility model provides an altimeter report height indicating device, this test device can accept the signal of telecommunication that comes from code altimeter or accurate altimeter and return to convert the signal into and correspond the altitude value and indicate, and detect code altimeter and accurate altimeter report altitude function.
In order to achieve the above purpose, the utility model provides a following technical scheme is: this aviation altimeter report height indicating device includes communication interface circuit, sets up at the singlechip of interface circuit output and sets up the display circuit at the singlechip output, and its technical essential is: the communication interface circuit comprises a communication interface with the encoding altimeter and a communication interface circuit with the precision altimeter, and the display circuit comprises a height indication and encoding state LED lamp indication part.
The utility model has the advantages that: the height report signal returned by the code altimeter or the precision altimeter is transmitted to the single chip microcomputer by the data communication interface circuit, the single chip microcomputer calculates and interprets the height (British system or metric system height, and the height can be selected through a key) corresponding to the code according to the received coded data, and then the code and the height value are transmitted to the display circuit to be displayed. To sum up, the utility model discloses can accept the height report signal who comes from code altimeter and accurate altimeter simultaneously to with the code and to just high demonstration output, easily observe and operate, reduce the complexity that detects, raise the efficiency.
