Embodiment 1

[0053] Such as figure 1 Shown is a schematic cross-sectional view of an infrared false door. The infrared false display door consists of four parts: the uppermost surface is a low-emissivity coating used to simulate the dark color of the thermal infrared image at the entrance and exit of tunnel engineering during the day. The next layer and the bottom layer are thin iron sheets, which are used to wrap the internal structure and ensure the overall strength of the door. The two layers in the middle are electric heating film and polystyrene foam plastic plate. The electric heating film simulates the thermal characteristics of the mouth by emitting far infrared rays, and the polystyrene foam plastic plate is used to support the flexible electric heating film.

Embodiment 2

[0055] The production method of the infrared false door:

[0056] 1. Cut the thin iron sheet according to the size of the entrance and exit door, according to figure 2 Fold the thin iron sheet in the way shown in the folding section, and the width of the middle groove is the door width.

[0057] 2. If image 3 Put the polystyrene foam plastic into the slot-shaped thin iron sheet as shown, and then spread the electric heating film on the foam plastic ( Figure 4 ), and fixed on the foam.

[0058] 3. If Figure 5 As shown, cover the upper thin iron sheet on the electric heating film, reserve the position of the electric heating film wire, and fix the upper thin iron sheet and the infrared display false door as a whole.

[0059] 4. Finally, spray low-emissivity paint on the surface of the thin iron sheet.

Embodiment 3

[0061] Such as Figure 6 Shown is the connection schematic diagram of the infrared false display system, and the intelligent control system is respectively connected with the infrared false display door and the solar photovoltaic power supply system.

[0062] The intelligent control system includes power supply, single-chip microcomputer, solid state relay, seven-segment digital tube, temperature sensor and so on. The power supply is used to provide low-voltage direct current to the components in the control system, and is mounted on the integrated circuit board of the control system. The single-chip microcomputer is used to provide data processing for the control system and is the core of the control system. The solid state relay is used to realize the closing and opening of the control circuit, and it is a tool to realize real-time control of the circuit. The seven-segment digital tube is used to set and display the relevant parameters required by the infrared false displa...

Abstract

The invention relates to the technical field of infrared camouflage equipment for entrances and exits of national defense projects, and discloses an infrared false indication system for tunnel engineering entrances and exits and a manufacturing method thereof. The infrared false indication system for tunnel engineering entrances and exits includes infrared false indication doors 5, intelligent control systems 6 and solar energy Photovoltaic power supply system 7, the infrared false door includes: low emissivity coating 1, electrothermal film 3, polystyrene foam plastic plate 4 and thin iron sheet frame 2, and the thin iron sheet frame 2 is wrapped with polystyrene foam plastic Plate 4, electrothermal film 3, and the outer surface of the iron frame 2 is coated with a low-emissivity coating; wherein, the electrothermal film 3 is connected to the intelligent control system 6 connected to the solar photovoltaic power supply system through cables. The invention can effectively simulate the entrance and exit of the national defense project, and the thermal infrared image is bright in daytime, and the thermal infrared image is dark in night. It realizes intelligent and real-time simulation of thermal infrared characteristics of entrances and exits; solves the problem of unavailable power supply in the field, and realizes the unattended infrared false display system.

Description

technical field [0001] The invention relates to the technical field of infrared camouflage equipment for tunnel engineering entrances and exits, in particular to an infrared false display system for tunnel engineering entrances and exits and a manufacturing method thereof. Background technique [0002] The mouth of the tunnel project is the most obvious exposed area of ​​the whole project, and it is the key part for the enemy to detect and carry out fire attacks. Mouth protection is the weakest link in engineering protection, and its survivability is directly related to the comprehensive protection efficiency of the entire project. With the continuous improvement of high-tech reconnaissance and discrimination capabilities, it is becoming more and more difficult to realize the concealment of targets, and it is often more cost-effective to take measures to show and camouflage targets, and has significant military value. [0003] With the development and improvement of infrare...
