Description

A shooting range photoelectric theodolite management and control platform

technical field

The invention relates to a control platform for a shooting range photoelectric theodolite.

Background technique

The photoelectric theodolite is an irreplaceable terminal measurement device in the construction of the shooting range. By interpreting the images taken by the optical measurement device, parameters such as the trajectory and attitude of the flying target can be obtained. These parameters are an important basis for weapon test identification and failure analysis, and the premise of obtaining these parameters It is to obtain high-quality target images.

The photoelectric theodolite is a complex system that requires high real-time performance with the cooperation of multiple sub-systems. The mutual cooperation of each subsystem needs to abide by the strict timing relationship. The photoelectric theodolite control equipment is the center of information transfer and processing of the entire system, mainly completing the configuration, monitoring and protection of each subsystem. Collect, receive, display, and save various data in real time and issue various control instructions to each subsystem in strict timing. Therefore, the control equipment is very important for the entire photoelectric theodolite.

The control equipment commonly used in photoelectric theodolite is composed of hardware part and software part running on it. Its operating principle is shown in Figure 1.

The hardware part of the photoelectric theodolite control equipment usually consists of a computer and related boards, while the software part is usually a comprehensive software that integrates all functions such as real-time acquisition, command issuance, and human-computer interaction. In the case of very limited computer resources, especially localized computer resources, the management and control equipment of this architecture may not be able to allocate enough resources in extreme cases. For example, the CPU runs at high load for a long time; the human-computer interaction part and the real-time data sending and receiving part affect each other.

It is difficult to expand the photoelectric theodolite control equipment using the above architecture. For example, when it is necessary to add several management and control devices to realize remote multi-point management and control, it is difficult to expand using the current architecture.

It is also difficult to carry out lightweight design for the photoelectric theodolite control equipment using the above structure. For example, it is necessary to transform the management and control equipment into an embedded or use a tablet computer. If the current architecture is used, it is difficult to transform.
