Technical Field

The invention relates to a laser signal receiving device, in particular to a scattering type omnidirectional laser signal receiving device, and belongs to the technical field of confrontation training of soldiers.

Background

The laser is emitted to replace live ammunition, so that the laser is an effective means for the actual combat practice of the army at present. A laser transmitter on the weapon emits laser to simulate the shot bullet, and an individual laser signal receiving device receives laser signals to indicate that the bullet is hit by the bullet. In the existing individual laser signal receiving device, the photoelectric signal receiver is horizontally arranged, and as shown in fig. 1 and fig. 2, laser information can be received only by directly irradiating the photoelectric signal receiver by laser. Because the laser beam has a certain divergence angle, the distance between the laser beam and the near laser spot is small, and the laser spot is larger as the distance is farther. The small light spots are not easy to irradiate the receiver, and the large light spots are easy to irradiate the receiver, so that the existing laser countermeasure system has the problems that short-distance shooting is not easy to hit, long-distance shooting is easy to hit, and the problem of great inconsistency with a real live ammunition shooting scene exists.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to provide a scattering type omnidirectional laser signal receiving device aiming at the defects of the prior art, which can receive laser information without directly irradiating a detector by laser and simulate a real firing practice scene.

Meanwhile, the invention also provides an individual harness containing the scattering type omnidirectional laser signal receiving device for solving the problems.

The technical scheme is as follows: the scattering type omnidirectional laser signal receiving device comprises a fixing plate, a central processing unit and at least 2 photoelectric signal receivers in communication connection with the central processing unit, wherein the photoelectric signal receivers surround the center of the fixing plate and are arranged in a side-to-side direction, and probes of the photoelectric signal receivers face outwards.

The technical scheme of the invention is further defined in that the number of the photoelectric signal receivers is 4, the photoelectric signal receivers are uniformly arranged around the center of the fixing plate in a side-standing direction, and the side receiving angle of each photoelectric signal receiver is larger than 90 degrees.

Furthermore, a filter circuit, an amplifying and shaping circuit and a comparison circuit which are sequentially in communication connection are arranged between the photoelectric signal receiver and the central processing unit.
