How did the gate come from?
The gate machine originated in Western countries or regions, and its original form is to use fences to raise livestock and leave a passage for people to pass. For the first time, Americans applied this concept to modern business, especially in places such as supermarkets. The earliest Gates appeared in the London Underground system in the late 19th century to control passengers entering and leaving the platform,The design of mechanical locking and swivel arm mechanism is adopted.
With the continuous innovation of technology, the function of the gate is also expanding. For example, smart gates rely on sensing technology, including infrared sensors, microwave radar, etc. to detect the direction of travel and identity information, and through the control circuit to open or close the gate operation. In addition, the gate has also experienced the evolution process from three-roller gate to fully automatic gate.
How does the gate work?
The working principle of the gate is mainly realized by the control circuit and sensor induction. When someone needs to pass, the gate will detect the direction and identity information of the person through the sensor, and then open or close the gate through the control circuit. Specifically, the gate is composed of channel indicator light, traffic indicator light, infrared sensor, etc,Its working principle is to drive the door wing to rotate through the servo motor, and detect the preset angle through the servo controller, so as to realize the control of opening or closing the door.

Different types of gates:
-
Semi-automatic: Through the electromagnet to control the movement and stop.
-
Fully automatic: through the motor to control the movement of the operation and stop.
-
Three-roller gate: It works in a special way, and will drop the rod in the case of power failure, which plays the role of fire passage.
-
The initial identification methods of Intelligent Channel gates include card swiping (such as magnetic card, IC card), document scanning and other methods to determine whether the user has legal access rights. In recent years, face recognition technology has also been introduced into the gate to further improve the recognition speed and accuracy.
What is the difference between the working principle and technical details of different types of gates (such as semi-automatic, fully automatic, and three-roller gates)?
Different types of gates (such as semi-automatic, fully automatic, three-roller gates) have significant differences in working principles and technical details.
Semi-Automatic gate machine:
Working principle: Semi-automatic gate through the electromagnet to control the movement and stop. This type of gate usually does not have a motor, so it is more reliable for use in harsh environments than the fully automatic type.
Technical details: Semi-automatic gate machine relative to mechanical gate machine to be stable, the cost is lower than the automatic type.
Full automatic type gate machine:
Working principle: The automatic gate machine controls the operation and stop of the movement through the motor. This type of gate usually has a higher degree of automation and higher operating efficiency.
Technical details: The fully automatic gate can be compatible with a variety of control equipment, such as IC card, ID card, magnetic card, barcode card, etc., and has a variety of working modes to choose from, such as one-way or two-way traffic.
Three-roller brake:
Working principle: The three-roller gate is generally composed of three rods, each rod is 1250mm long, and the gap between the three rods can only accommodate one person, which is suitable for one-way or two-way control of people. The brake lever of the three-roller brake runs smoothly and has low noise, and has the function of power-off emergency, that is, the brake lever will automatically fall off when power is off and will be automatically put on when power is on.
Technical details: the movement of the three-roller brake adopts all-alloy steel spindle and the "installation method of the three-roller brake spindle with shape deformation" patented by central control, which can withstand strong impact and can operate normally with moderate deformation. In addition, the three roller gate also uses a unique incomplete gear transmission system, so that the gate in the zero position lock, unlock more accurate and reliable.
Different types of gates have obvious differences in working principles and technical details. The semi-automatic gate machine relies on electromagnet control and is suitable for harsh environments; The fully automatic gate machine is controlled by a motor and has a higher degree of automation.
The development of the gate from the initial simple mechanical device to the current intelligent equipment has not only significantly improved in function, but also more extensive in application scenarios. The core of its working principle is to achieve precise control of the passage state through sensors and control circuits.
What are the main application scenarios of the gate:
Public transportation:
Gates are widely used in transportation hubs such as subway stations and airports to help managers control passenger flow and ensure order in the station. In addition, the gate can also be linked with the subway ticketing system to achieve automatic ticket checking and improve operational efficiency.
Enterprises and institutions:
In Enterprise Buildings, the gate can effectively manage employee access, improve safety and management efficiency. In addition, the gate can also be linked with the access control system and employee card system of the office building to realize intelligent management.
Commercial premises:
In commercial places such as shopping malls, supermarkets and office buildings, gates are widely used to effectively control the entry and exit of people, prevent illegal intrusion, and ensure the safety of the business environment.
Safety precautions:
The application of the gate in the field of security is also very extensive, and can be used for access control in residential areas, office buildings, schools, hospitals and other places. In addition, the gate can also be applied to any place that requires real-name security checks, including single or mixed use of certified access and paid access systems.
Community Management:
In the community parking management and other aspects, the gate also played an important role. For example, in the access control of residential areas, the three-roller gate can effectively prevent unauthorized personnel from entering.
Other application scenarios:
The gate is also widely used in the attendance system of factories, the consumption system of institutions, the ticket inspection system of venues such as scenic spots, and the attendance system management of construction sites. In addition, face recognition gates are also widely used in scenes such as the gate of government agencies and the import and export of unit office areas.
In these scenes, the single function of the gate can no longer meet the needs of diversified scenes, so the gate with LCD screen was born.
What is the role of intelligent gate?
Especially in the subway, outdoor access control and other scenes, the LCD screen is not only used to display information, but also has a variety of functions, such as identification, status indication, interactive interface, advertisement playback and emergency information release, which greatly improves the user experience and operation efficiency.
Specifically, the 6.5-inch LCD screen is widely used in subway gates to provide real-time information display, including fare information, station name and time, which significantly enhances the travel experience of passengers and improves the efficiency of subway operations. In addition, the LCD screen can also be used to display the gate working status and passenger card related information.
The choice of LCD screen needs to consider its adaptability in different environments, including high resolution, high brightness, full viewing angle, high protection level and long service life. For example, the LCD screen used in outdoor access control gates should not only improve the overall performance, but also enhance the appearance design to provide users with more convenient and efficient services.
The application of intelligent LCD display module is also very extensive, not only limited to subway gates, but also includes supermarket electronic scales, new energy vehicle charging piles, medical inspection equipment, etc. These modules usually use single-chip microcomputer control system, in order to achieve Chinese display, scroll and move around and other functions.
