Description

Be used for integrative equipment of laser receiving and dispatching

Technical Field

The utility model belongs to the technical field of the analog device and specifically relates to a be used for integrative equipment of laser receiving and dispatching.

Background

Laser receiving equipment has extensive use in army's military training, rehearsal, and traditional laser receiving equipment only has the laser receiving function, can not discover after the cheating shelters from to the mounting point position is many, all has the installation on helmet, clothes, laser emission rifle respectively, and it is extremely inconvenient to use, in giving the simulation actual combat demonstration, has brought uncertain factor.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a laser receiving and transmitting integrated device, which adopts the modular design and is convenient to install and maintain; the laser communication connection is adopted with the laser emission gun, so that the use is convenient; the shielding detection is provided, and cheating is effectively prevented.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is:

a laser receiving and transmitting integrated equipment comprises an optical filter, a laser receiving and transmitting integrated device and a laser transmitting and receiving integrated device, wherein the optical filter can filter out ambient stray light;

adopting 485 bus communication and passive polling mode;

the optical signal with fixed wavelength is received, and is processed by filtering, amplification and the like, and the optical signal is decoded and cached by the CPU, and when 485 inquires the received data, the data is sent out.

The CPU codes to control the I/O to output high and low levels, and the constant current processing circuit controls the on-off of the laser emitting tube to emit laser signals.

The laser emission is divided into two types, one type is used as shielding detection, the CPU sends fixed coding information, and when a shielding object exists, the laser receiver can receive a laser signal sent by the laser emission tube of the laser receiver; when the shielding is not available, the laser receiver cannot receive the laser signal sent by the laser transmitting tube; the other type of the communication module is communicated with the laser emission gun, encodes data received by 485 communication and sends the encoded data to the laser emission gun.

And a 3.3V-5V power supply is adopted to supply power to the equipment.

The utility model has the following beneficial effects and advantages:

1. the utility model discloses installation light filter reduces ambient light and disturbs.

2. The utility model discloses laser receiver divergence angle is big, guarantees effectual receiving range.
