In terms of material, we have also talked about it before. The three-roller case is made of standard 304 stainless steel or customized 316 stainless steel, and the internal components of the three-roller case are all made of stainless steel or anti-rust and anti-corrosion treatment, which is durable Anti-rust, strong destructive power, safe and reliable. This is only an object that we can see with the naked eye, but how can we make the three roller gates that we usually look dull more humane and smarter? How should it be done?

As a professional manufacturer of three-roll gates, we are confident to tell you that we are professional to make three-roll gates more humane and more intelligent. Let me speak slowly.

First of all, anti-following, anti-following, anti-submarine, anti-reverse transmission, anti-reverse illegal entry into the channel, our equipment is equipped with sophisticated infrared alarm sensors, as long as anyone violates the principle of one person, one shot, these will be triggered Function, which is very good to protect our personal safety, but also greatly helps our management to better regulate the user’s traffic behavior.

Secondly, you can choose a variety of dazzling colors. The three-roller gates we usually see are a single stainless steel appearance, the overall appearance is single, visual fatigue, and even inconsistent with the overall match of some on-site environments, so we are based on the principle of customer first , Re-design the appearance based on the original equipment, so that our three-roller gates have more appearance options, such as marble countertops, LED lighting decoration, stylish and beautiful appearance structure, allowing customers to have more choices. This is not possible with ordinary three-roll gates, especially those mass-produced. Only customized turnstiles can achieve a more humane design.

Thirdly, for functional customization, in addition to traditional RFID card swiping control, we can also customize face recognition, fingerprint recognition, palm vein recognition, and facial province certificate contrast recognition for customers, making it more secure and more in line with the current Internet of Things Concept docking.

Through the above explanation, I believe that everyone has a better understanding of the choice of three-roller gates. I hope our explanation is useful to you, and I hope you can choose a channel gate that suits you.

Introduction to License Plate Recognition System

The management of vehicles is an important aspect. Especially for special parking lots, courtyards, government agencies, and communities, all kinds of vehicles are required to be strictly managed in real time, their time of entry and exit should be strictly monitored, and all types of vehicles should be registered (including internal and external vehicles). Vehicles) and identification. In large-scale fields, there are many vehicles entering and exiting. For example, each vehicle must be manually judged, which is time-consuming, not conducive to management and inquiries, and the security work is difficult and inefficient. In order to improve this management mode that is not commensurate with modern parking lots, courtyards, government agencies, communities, etc., it is necessary to automate and intelligentize vehicle management as soon as possible, and manage it in the form of a computer network, so as to effectively control all vehicles at entrances and exits. Locally and accurately monitor and manage. The system is required to provide corresponding application software to realize the efficient and intelligent management of the camp.

Use the automatic license plate recognition algorithm of the video stream, or trigger by the sense of ground, to capture the vehicle and recognize the license plate. When the vehicle enters the entrance of the community, the automatic license plate recognition algorithm automatically captures the vehicle photo and recognizes the license plate number. The license plate number, color, and license plate Characteristic data, admission time information, etc. are transmitted and recorded, and vehicles can enter and exit the parking lot without barriers, providing users with a brand-new service mode.

The system automatically recognizes the number and license plate characteristics of the vehicles entering the community, verifies the legal identity of the user, automatically compares the blacklist database, automatically alarms, and can monitor and manage the entire parking lot, including entrance and exit management, internal management, collection and storage of data And the working status of the system, so that the administrator can monitor, maintain, count, query and print reports.

Introduction to Access Control System

The access control system is also called the access control-access control system. It is a highly intelligent, real-time control and offline access monitoring and alarm management security system. Each authorized user holds a non-contact IC card, and the cardholder will enter the relevant door according to the authorization obtained. The system realizes the alarm function by fortifying the specific management area (alarm status). The system automatically reads the card time, door opening information, card holder, alarm information and other data for query and statistical processing and generates various reports. It is used in modern office buildings, banks, factories, computer rooms, intelligent communities, etc.

Access control system composition

The access control system generally includes 3 levels of equipment. The ground floor is the equipment that directly interacts with personnel, such as card readers, electronic locks, and exit buttons. They are used to accept the information input by personnel, and then convert them into electrical signals and send them to the controller. At the same time, they lock the work according to the signals from the controller. The controller accepts the information about the personnel sent by the bottom device, compares it with the information stored by itself to make a judgment, and then sends out the processed information. A single controller can form a simple access control system to manage one or several doors. Multiple controllers are connected to the computer through the communication network to form the access control system of the entire building. The computer is equipped with the management software of the access control system, which manages the analysis and processing of the information in the system.

Access control system features

1. Stability: product performance is stable and reliable, which is mainly reflected in long-term trouble-free operation.

2. Anti-interference: reasonable circuit design, professional wiring connections, strong resistance to interference from external factors such as electrostatic discharge, electromagnetic waves, and lightning.

3. Convenience: The operation is simple, fast and convenient when the personnel apply for legal passage through the entrance and exit. The operation interface of the staff for the daily maintenance and management of the entire system is intuitive, simple and friendly.

4. Compatibility and openness: Under the condition of ensuring the stable operation of the access control system, the control host can be connected to a variety of card readers. The system has good flexibility and scalability, and can take into account the project budget and project implementation requirements.

Wiring specification of security monitoring system

The wiring of the security monitoring system will involve many aspects. Because of the differences involved, most of the functions are different, and the cable types to choose to install are not the same. Below we mainly focus on the wiring specifications required for the installation of some security monitoring systems. Learn it. The following is about the wiring specifications of the security monitoring system:

1. Camera video signal transmission cables used in security monitoring systems. The commonly used video transmission cables are 75Ω series thin coaxial cables, but coaxial cables with different diameters have different attenuation levels for video signals. The thicker the cable, the attenuation The smaller. The characteristic parameters of the coaxial cable series are shown in Table 1. It is required to select cables according to Table 1. The thicker the cable diameter, the smaller the attenuation, and the more suitable for long-distance propagation. The cable selection is as follows: when the distance between the camera and the sub-monitoring center is less than or equal to 300 meters, SYV-75-3 can be used; when the distance between the camera and the sub-monitoring center is less than or equal to 500 meters, SYV-75-5 can be selected; when the camera is to the sub-monitoring center When the center distance is less than or equal to 800 meters, SYV-75-7 or SYV-75-9 can be selected; when the distance between the camera and the sub-monitoring center is less than or equal to 1000 meters, SYV-75-12 can be selected;

2. Security monitoring system camera power cord The power cord in the TV monitoring system adopts separate wiring. The main switch is set in the monitoring room and the UPS power supply is used to directly control the entire monitoring system. Under normal circumstances, the power cord is wired according to AC 220V. The camera end is then converted into DC 12V by the adapter. However, some cameras use 5V or 12V or 24V direct current, and the power supply method is different.

3. Use camera device cables with motorized pan/tilt and motorized lens For camera devices with motorized pan/tilt and motorized lens, in addition to the above-mentioned video signal lines and cables, the transmission cable between the on-site decoder and the control center should also be considered Generally, 2-core shielded communication cable (RVVP) or category 3 twisted pair is used, and the UTP core cross-sectional area is 0.3m㎡~0.5m㎡.

4. Security monitoring alarm and sound monitoring cable monitoring warehouse, the alarm and monitoring warehouse cable in the corridor generally use 4-core shielded communication cable (RVVP) or category 3 twisted pair UTP, with a cross-sectional area of 0.5m㎡ per core.

5. When broadcasting and intercom cable monitoring warehouses, corridors, factory areas, etc. set up broadcasting, the basic principle of security monitoring cables is: the longer the distance, the thicker the cable. The basic communication distance stipulated by RS-485 communication is 1200 meters. In the actual project, the RVV-2/1.5 sheath line can be used to extend the communication distance to 2000 meters. Different lines can be selected for the length of the visual distance for broadcasting and intercom. Cable, twisted pair.

6. Computer network cables Computer network cables are divided into two categories. One type uses optical cables between vertical trunk lines and buildings, and the other type uses 4 pairs of 8-core shielded super Category 5 cables for horizontal trunk lines. According to the actual situation of the prison project, a 50μm/125μm fiber optic cable was selected between the buildings. Multi-film optical cables are used for sub-monitoring to the sub-monitoring center, and single-film optical cables are used from the sub-monitoring center to the main monitoring center. Use 4 pairs of 8 core super Category 5 shielded twisted pairs from work area to management room.

The above are the six normative principles of the wiring specification of the security monitoring system. When the wiring is arranged, there will be no more trouble with the selection of cables. I hope it helps.

Zhongyang parking lot management system equipment

As people's lives improve, many families choose to buy cars and go out for fun. The rapid increase of cars is followed by the shortage of parking spaces. During the Golden Tourism Week, parking is difficult to become a part of life. At this time, the parking lot needs a management system to manage it, which can reduce manual workload and also work well Make full use of the space in the parking lot without waste of resources.

One of the reasons why the license plate recognition parking lot system is so popular is to speed up the speed of people entering and leaving the parking lot. Because of its special function, it is currently used by people in all parking lots of various sizes. So when buying a license plate recognition parking lot system, which aspects should be considered? What are the core equipment? The license plate recognition parking lot system and ordinary parking lot system are roughly the same in composition, but the license plate recognition parking lot system has equipment requirements Will be higher.

First of all, an important factor in the license plate recognition parking lot system is the recognition rate. Some people judge the quality of the equipment from the recognition rate. In fact, this is a very unscientific method. The recognition rate is not only related to the problem of the device itself, but also related to the environment of the parking lot. The impact of the environment on the recognition rate may sometimes exceed the factor of the device itself. Therefore, to solve this problem, the license plate recognition parking lot must not only be equipped with a high-definition license plate recognition camera , And install some supplementary light equipment according to the site conditions to increase its recognition effect.

Secondly, the important feature of the license plate recognition parking lot system is the fast passing speed. Therefore, compared with the card parking system, the barrier must use the fast intelligent barrier, and the fast barrier will have higher requirements for the movement of the barrier. Its stability is stronger.
