Detailed description of the invention
Fig. 1 is the principle of the present invention block diagram；
Fig. 2 is mounting arrangement figure of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments:
As shown in Figure 1, a kind of trampoline locating and detecting device, including X-axis grating sensor 1, Y-axis grating sensor 2, data processing
Circuit 3, power circuit 4, storage circuit 5 and output display circuit 6.
X-axis grating sensor 1 jumps for measuring trampolinist's X-axis landing point coordinates, Y-axis grating sensor 2 for measuring
Bed motion person's Y-axis landing point coordinates, data processing circuit 3 are used to read the coordinate signal of grating sensor output, and power circuit 4 is used
In the power supply of trampolinist's drop point site detection system, storage circuit 5 is used to store the landing point coordinates position of sportsman, output
Display circuit 6 is used to amplify sportsman's drop point site and shows and upload the data to monitor supervision platform.
X-axis grating sensor 1 and Y-axis grating sensor 2 are realized using the erection sequence of layered arrangement to sportsman's drop point
It is detected with extreme lower position.
Data processing circuit 3 is developed using PLC or micro-chip processor, and data processing circuit 3 is by reading grating
The output coordinate signal of sensor.Data processing circuit has the function of time bias, by calculating sampling time interval, to drop point
Coordinate data compensate.
Data processing circuit 3 passes through data/address bus for the specified deposit of sportsman's landing point coordinates information write storage circuit 5
In device.Storage circuit should meet 100,000 times or more data storages.
Output display circuit 4 includes LCD Panel and host computer communication interface, and LCD Panel will be for that will move
The drop point site of member amplifies display.Output display circuit is connected by communication cable with monitor supervision platform, and data use communication party
