Three-roll gates, swing gates, wing gates and other channel gate products are used in the form of connection with other systems in practice. Therefore, the understanding of the composition of the channel gate system has become an indispensable part for dealers and engineering companies. Knowledge point, here is a comprehensive analysis of the relationship between the various modules of the channel gate system and the relationship between the system and the gate.
First, the introduction of the system
A system is an organic whole (collection) with specific functions combined by a number of interconnected and mutually constrained components.
For the channel management system, the software part and the hardware part are combined, through various signal identification transmission, mechanical action, so that it has a whole management and control function for the personnel entering and leaving the channel.
Second, how is the system module differentiated?
1. User profile
(card / barcode / body fen certificate / fingerprint / face ...)
2. Front end identification device
(IC/ID read head, 1D/2D barcode scanner, fingerprint reader, Bluetooth reader, face recognition camera, fen card reader...)
3. Mid-end control equipment
(Access Control Panel/Parking Control Board/Ticketing System Control Board/Fingerprint Machine/IPC,)
4. Data transmission equipment
(RS485 communication converter / network cable router)
5. Backend software equipment
(Access Control Attendance System / Parking System / Consumption System / Ticketing System ....)
6. Authorized equipment
(IC.ID card issuer / fingerprint collector / barcode scanner /)
7. Database
(SQL2000 is commonly used)
8. Control equipment
(Pedestrian passage gates, roadway gates.......)
Third, how is the function of each module defined?
1. User profile
Some small storage media or biometrics that represent the user
2. Front end identification device
Read some data representing user information
3. Mid-end control equipment
Accept the user information, store the user information, determine the legitimacy of the user and give the corresponding action output, and play the micro-intelligent module that uploads the report and can make the judgment.
4. Data transmission equipment
Convert the data that needs to be transferred to what the receiving data can recognize
5. Backend software equipment
The basic platform of the entire system, all the information needs to be summarized here and distributed to each module.
6. Authorized equipment
Like the front-end identification device, it has the device that reads the information representing the user, the difference is that some authorized devices have the write function.
7. Database
a specific hard disk space that stores all system data
8. Control equipment
The device that ultimately responds to system commands and makes a release or no release action has some independent functions.
4. What is the relationship between system modules and information exchange?
V. System summary
Various systems have their own characteristics, but the overall modules and functions are similar, and some special modules have relatively strong scalability. In short, no matter how the channel management system is ever-changing, it is inseparable from the above modules. The representation of each sub-system of knowledge is named according to the system itself, and the channel gate is the last execution in the whole system. The role of the "lock" of the command, although only a small part of it, but the success or failure of the entire system is now on the channel gate, so the choice of a stable channel product directly determines the success of the entire system.
