How to choose gates in engineering projects
The smart channel gates used in security projects mainly include seven types: three-roll gates, swing gates, wing gates, sliding gates, turnstiles, in-line gates, and barrier-free passages. Their respective characteristics are as follows:
2. Swing gate: The styles are more diverse, including bridge, vertical, cylindrical, etc. The swing arm material is also diverse,
There are stainless steel, plexiglass, tempered glass, etc., generally stainless steel and plexiglass are mostly used. Tempered glass has higher process requirements and is generally used in more high-end occasions. One can form a channel, or two sets can form a channel.
3. Wing gate: The biggest feature of the wing gate is its fast traffic speed, beautiful appearance, diverse styles, and smaller passage width than the swing gate, which is more suitable for occasions where the flow of people is not concentrated. Must be in pairs to form a channel.
4, the sliding door: developed from the wing gate, borrowing the characteristics of the automatic door. There are two types of full-height and half-height. Full-height turnstiles can effectively prevent people from climbing and crossing. The baffles are generally made of tempered glass or plexiglass, and they must be paired to form a channel.
5. Turnstiles: Turnstiles are the characteristics of comprehensive revolving doors and three-roller gates, and are the highest level of security. The working principle is similar to three-roller turnstiles. They are divided into 90-degree turnstiles and 120-degree turnstiles, which can be effectively realized. A single pass for a single pass has a greater precautionary position, which shows a stricter mandatory control than the persuasion level, and is more suitable for occasions with higher security requirements. It can be single-channel or multi-channel.
6, one-shaped gate: similar to the swing gate, the gate rod is opened up and down, the gate rod is 300---500MM, which can be opened to form a channel or split to form a channel, which is less used. It can be single-channel or multi-channel.
7. Barrier-free passage: Similar to the security gate, it mainly uses infrared detection to realize the alarm for illegal passage. It is mainly used in some occasions where the flow of people is particularly large, or large objects are needed.
To start the preparations for a security engineering project, the first consideration is to select the appropriate turnstile. The so-called appropriate turnstile is to choose a cost-effective one for the specific project, including the application site environment, the flow of people in and out, and some special functional requirements. product.
The following examples illustrate how to select gates for different occasions"
1. For scenic spots, parks, factories and other occasions, the three-roller gate is a good choice. Its biggest feature is that it can effectively achieve a single pass, and realize one-way access and personnel flow, and cost Lower. In engineering use, it can be combined with access control to organically integrate access control, attendance and people flow control. The combination of scenic parks and electronic tickets can realize automatic ticket checking and ticket checking. Compared with manual ticket checking, it not only improves efficiency, but also impresses tourists and enhances the image of the scenic spot.
2. For residential areas and concentrated residential areas, the flow of people is easy to reach peaks in certain time periods, and there may be large objects such as electric vehicles and bicycles passing through, so generally swing gates are used to combine wing gates or three-roller gates. Matching can not only solve the circulation of peak people, but also meet the special needs of specific groups of people.
3. For stations, subways, airports and other occasions, where the flow of people is very large, and there will be people carrying luggage, these can choose some swing gates and wing gates equipped with infrared, which have the characteristics of high speed and wide passage, and It can effectively prevent illegal passage such as package tickets, trailing, turning back, etc. In addition, the width of the passage of the swing gate is larger, and it can also provide the possibility of special passage for the disabled.
4. For some high-end places, more harmonious high-end wing gates, sliding gates, and luxury swing gates can be used. Such occasions have higher requirements on the noise, performance and aesthetics of the gates.
5. For prisons, military control areas and other occasions where the security level is very high or the flow of people is very strict, the full height turnstile is a very suitable choice.
6. For some complex systems that require supporting electronic tickets, photographs, ID card recognition, etc., it is recommended that the project leader and our company's technical staff communicate the details of each functional requirement, determine the drawings, and then select and purchase.
7. The selection of the number of gates is mainly determined by the reserved width and the flow of people on site. Once the reserved position is determined, the number of gates is basically determined. Generally, the speed of gates is 20-30 people per minute, and you can simply calculate how many gates you need depending on how many minutes it takes for the personnel to pass.
