(1) Advantages

① The simulation of crowded crowds has a high degree of simulation;

② Realize crowd stationary, co-movement and hedging movement scenarios, with rich training content;

③ The utilization rate of the site is close to 100%;

④ The system has high reliability and is convenient for later maintenance.

(2) System composition

① The chain drive system is mainly composed of rails, traction chains, sliding frames, spreaders, steering devices, driving devices, tensioning devices, safety devices and hanging sandbags.

② The track forms a closed loop on which the carriage runs.

③ The traction chain forms the same closed loop as the track line through the horizontal redirecting device.

④ The spreader carries sandbags and is hinged to the carriage.

⑤ The chain drive system adopts the frequency conversion speed regulation control system.

(3) How the system works

The design of the S-shaped overhead track can realize the left and right swing of the human-shaped sandbag during the transmission process, more realistically express the collision state during the training process, and make full use of the venue.

The human-shaped sandbag is fixed on the carriage at two points, limiting its torsional freedom in the horizontal plane during the transmission process.

Several annular hanging rubber sandbag chains in the system are centrally controlled by a set of PLC system. Different movement modes can be programmed according to training needs and can be switched freely, and new movement modes can also be added according to needs.

The start and stop of the system are realized in three ways: normal control in the command room, emergency braking control in the command room, and emergency braking control for training police officers to ensure that the training process is controllable.

The speed of each ring of hanging rubber sandbags can realize stepless speed regulation, which can simulate different sandbag moving speeds at different times or simulate the sandbag variable speed movement in the same training.

The number and spacing of the sandbags suspended in each ring can be adjusted according to the training needs, and the power devices of each ring are individually controlled to realize the start, stop, forward, backward, acceleration and deceleration of each ring.

The movement mode of each ring (different speed, different direction, different acceleration) can be programmed according to the actual use requirements, and various movement modes such as differential speed and crossover of sandbags can be realized.

A sandbag suspension device is set up at one end of the field, and the number of suspended sandbags can be adjusted to simulate different crowd densities and enrich the training form.

On the two 20-meter long sides of the training ground, 10 ultra-short-focus reflective projectors are arranged on each side, together with the image fusion server, the multi-pass synchronous playback server, and the multi-screen expander. present a complete picture. Immerse the trainee police officers as if they were dealing with them at the scene.

The video content is post-produced by the panoramic camera on-site shooting. The movement of the screen matches the activities of the human sandbag, as if the scene is upstream, adding a sense of realism.

Equipped with 4 high-definition cameras, it can capture full-field video images in all directions. Through the camera control keyboard, you can observe the details of the training from multiple angles and multiple zooms. Provide the commander with the necessary command screen basis.

audio system
