Problems solved by technology

This can lead to incorrect input! And as long as there is an error output generated by a photosensitive detection device, it is likely to cause a completely different program logic output.
In addition, in the scheme of using laser light curtain, the photosensitive detection device is required not only to be sensitive and reliable, but also to be able to reflect light with high reflectivity! There is also the problem that the preparation process is difficult and the cost is high

Embodiment 1

[0028] This embodiment provides a channel detection device, which includes: a controller and one or more sets of forward detection components; each set of forward detection components includes a laser emitting module and a corresponding laser receiving module; each The laser emitting module in the group of forward detection components includes n laser generators, and the corresponding laser receiving module includes n photosensitive detection components, n≥3; n laser generators are arranged in sequence, and the controller according to n The arrangement order of the laser generators sets the weight of the laser signals they send out in descending order.

[0029] Such as figure 1 As shown, for ease of description, the numbers of the n laser generators in a group of forward detection components are (1-1, 1-2, ..., 1-n); the numbers of the corresponding photosensitive detection components are ( 1-1a, 1-2a, ..., 1-na). figure 1 Controller not shown. figure 1 Controller not shown...

Embodiment 2

[0041] Based on the passage detection device described in Embodiment 1, this embodiment provides a universal personnel passage device, such as figure 2 As shown, the personnel passage device includes a gate and the passage detection device described in Embodiment 1; the gate is connected to the controller in the passage detection device, and the controller according to the forward detection The detection result of the component controls the opening and closing of the gate.

[0042] Specifically, the passage detection device includes a set of forward detection components as an example, and the controller judges the direction of travel of pedestrians according to the fact that the laser signals generated by n laser generators in the forward detection components are blocked and forward speed:

[0043] 1. If the laser signals generated by n laser generators are all blocked, and then restored in order according to the weight from high to low, it means that the personnel are movin...

Embodiment 3

[0059] Based on the passage detection device described in Embodiment 1, this embodiment provides a universal personnel passage device. The difference from Embodiment 2 is that this application includes not only forward detection components but also reverse detection components; The weights of the laser signals emitted by the n laser generators in the reverse detection component decrease successively.

[0060] In one embodiment, each of the forward detection component and the reverse detection component includes a group, and the actual passage of people is determined according to the comprehensive detection results of the two. Such as image 3 As shown, in order to distinguish the laser generator and photosensitive detection component contained in the forward detection component and the reverse detection component, they are represented by black and white graphics, wherein the black figure belongs to the forward detection component, and the white figure belongs to the reverse de...

Abstract

The invention discloses a channel detection device, a personnel channel device and an article detection channel device and belongs to the technical field of security gate channels. Laser signals emitted by n laser generators are properly set, so that the logic weights of the laser signals are sequentially reduced, and therefore, the problem that the laser intensity is weakened due to the adoption of a physical weight mode, and the problem that the detection accuracy is low due to the fact that it is difficult to guarantee that multiple laser beams are accurately, reliably and continuously aligned with a laser detection device at the same time are solved; by means of a light scattering device of which the area is far larger than that of the photosensitive area of a photosensitive detection device, the laser alignment probability is improved, and the detection accuracy is further improved; the light scattering device reduces the laser brightness in unit area, so that the damage of high-brightness laser to the photosensitive detection device can be reduced, and the service life of the photosensitive detection device can be prolonged; and the eight laser generators and the eight photosensitive detection assemblies are arranged, eight photoelectric signals are generated and correspond to eight bits of one byte, so that a laser optical system and a computer system can be conveniently integrated.

Description

technical field [0001] The invention relates to a channel detection device, a personnel channel device and a cargo detection channel device, and belongs to the technical field of security turnstile channels. Background technique [0002] The security gate is the most common device used to manage the flow of people and regulate the entry and exit of pedestrians. Its essential function is to pass through only one person at a time by blocking and releasing. Such as high-speed rail, subway entrance and so on. However, in order to realize that only one person passes at a time, it is necessary to solve the trailing problem accurately and reliably. At present, there are two main types of detection methods for personnel channel systems that have been finalized and produced in the market: one is the infrared detection method; the other is the camera system detection method: [0003] The full name of infrared intrusion detectors is "active infrared intrusion detectors". Its basic st...
