OPTICAL-ELECTRONIC SHOOTING TARGET OF MODULAR TYPE Russian patent published in 2023 - IPC G01B9/27 F41J5/02 

FIELD: sports equipment.

SUBSTANCE: method for constructing sports targets for training and competitions using firearms and airguns. A significant difference between this technical solution and the existing ones is the ability to build electronic targets with the required working field size using basic modules of the same type. Each of these modules contains a limited set of photodetectors placed optically in conjunction with two radiation sources, and contains input and output serial ports for receiving and transmitting information, as well as a control interface. The control interface signals of each fixation module are connected to the computing device, and when at least one photodetector of any of the fixation modules is shaded, a signal is generated on the interrupt line and sent to the input of the computing device. Next, control pulses generated by the computing device produce a bit-by-bit shift of the information recorded in the modules from the furthest module in the chain to the input to the computing device. After the information is completely entered into the memory of the computing device, it determines the coordinates of the point where the bullet hits the registration zone.

EFFECT: simplification of the electronic circuit of the device, exclusion of expensive high-speed LSIs with a large number of contacts, as well as possibility of manufacturing electronic targets of various sizes using the same type of basic photodetector modules, sequentially connected to each other and covering the perimeter of the hit detection plane.
