Chapter One Design General Description
In order to strengthen the management of its personnel and vehicles, a large enterprise requires strict management and control of the internal and visiting personnel of the unit. It adopts advanced RFID radio frequency identification technology to realize automatic tracking and control of incoming and outgoing personnel. The employees of this unit are talented with their cards. When entering and exiting, foreign people without a card enter the detection and alarm; at the same time, it is also required to reflect the humanization and intelligence of technology. The smart card for employees can be carried arbitrarily, which does not give employees a sense of control, and is convenient for employees to use. It is adopted for management of external visitors. The second-generation ID card reader registers and issues the card and authorizes the access control channel corresponding to the defended person. The unit vehicle is automatically identified and released at a long distance, and the system is required to not visually damage or obstruct the original building to maintain the overall delicacy and beauty of the building. An advanced management method, and to achieve it at a lower cost.
Chapter 2 Demand Analysis
1. Access control system: Due to the large number of personnel in the unit, the access control system should work in a fully automatic card reading method. For the personnel passage at the unit gate, employees can enter and exit normally as long as they have a card. Places such as computer rooms should be entered in the form of active card swiping. As the key point of the whole system, long-distance card reading requires the following points:
The induction card carried by the employee should be carried arbitrarily, and the card can be put in the employee’s pocket, bag or hung in front of the employee as an identification card.
The sensing distance of the card should not be too far or too close. If the distance is too far, the employee will produce wrong records when passing by the channel, and if the channel is too close, the channel will not be sensed.
In order to reflect human care, the card cannot be directional and can be placed arbitrarily, and employees must not be required to place the card in order to identify it.
The system must have multiple identification and anti-conflict capabilities. There are a lot of people entering and leaving at the same time during the peak hours of employees’ commuting, and the system must ensure that all cards can be accurately identified at a high speed.
The system must accurately determine the direction of entry and exit of personnel, and can not simply record incidents to prevent false entry and exit.
The radio frequency signals generated by the card readers and proximity cards must be harmless to the human body, because employees spend most of their time within the signal range, and the safety of everyone cannot be abandoned for the convenience of management.
2. Attendance system: employees have specific entry and exit time and records when entering and exiting the access control channel. The system does not need to set up other attendance equipment, and directly uses the entry and exit data of the access control point in line with the work time as the attendance record.
3. Consumer system: The consumer system uses the employee’s access card to directly consume, all data is transmitted under the network, and the data between the consumer machines must be automatically synchronized.
4. Visitor system: For foreign visitors, register by directly reading the information of the second-generation ID card of the visitor. For the first-generation license or driver’s license, automatic scanning and text recognition scanners should be used, and the visitors should be photographed. Those who need to enter and exit the entrance control point Places issuing visitor access cards.
5. Vehicle management system: All vehicles of this unit are assigned a long-distance sensor card. When the vehicle arrives near the gate, the gate will be opened automatically, and the foreign vehicle will be released after manual registration. For the vehicles that the cooperative unit enters and exits for a long time, you can also consider installing a long-distance card to facilitate its entry and exit.
Chapter III Implementation Plan
The first section system description
1. System principle
This system is designed using the latest CypherTag™ series TV6 proximity card and RV1 card reader from IDENTEC in the United Kingdom. CypherTag™ is the fourth-generation low-frequency radio frequency automatic identification brand developed by the company in the United Kingdom. CypherTag™ series proximity cards and readers are truly fast and long-distance induction radio frequency identification products, with a card reading distance of up to 3 meters, covering a channel width of up to 3 to 32 meters, and can identify up to 320 proximity cards at the same time , The card reading speed can reach 80km/h, so it can accurately identify and track the direction of fast-moving objects or people from a long distance. In the field of low-frequency radio frequency identification, CypherTag? induction technology is at the world’s leading level.
The working mechanism of the CypherTag? series of remote sensing products is: each proximity card has a 64-bit number. When the proximity card appears within the reading range of the reader, the proximity card is continuously emitted by the reader. The signal wakes up, so as to feed back to the reader a response signal carrying the proximity card number. Through the inquiries and responses between the proximity card and the reader, the reader can accurately and quickly identify the card carried in the proximity card. And output the read proximity card number to an external controller or other terminal equipment in a certain output format, so as to realize the identification of the proximity card.
The management center issues a card to each employee. When the employee passes the card reader antenna (with a reading distance of 3 meters), the card reader can sense the card and transmit the card number in the card to the local controller. The controller judges the access authority of the card, controls the opening of the corresponding door control equipment, and transmits the received card number to the management software. The management personnel can monitor and manage the entry and exit of each door in real time. The software directly adopts the personnel to meet the working hours The incoming and outgoing data is used as attendance data.
For important entry and exit areas, the system is equipped with a photoelectric column with anti-tailing function. The column can emit multiple pairs of infrared beams with a diameter of only 2.5 mm. The system can promptly identify unauthorized persons who are trailing behind legal persons trying to enter the passage. The center sends out audible and visual alarms, and can also capture photos of illegally passing people through the camera for future verification. At the same time, it can send in and out information to the manager’s mobile phone or mailbox. The personnel with the card will be authorized by the controller and no alarm will be generated. record. The system has no physical barriers, which is convenient for people to pass through quickly, and at the same time, it can prevent unauthorized persons from illegally passing through without swiping cards, realizing real fast passing.
For foreign visitors, use the visitor registration machine to directly read the second-generation ID card, the first-generation ID card and other documents to automatically scan and recognize, use a high-precision camera, and automatically take pictures when visitors register. Management software, to authorize the visitor’s office access control permissions, the software automatically displays the visitor information when the visitor passes the access control point at the entrance of the building, and the visitor without a card will generate an alarm when he passes by, and he can swipe his card to sign out when he leaves. Barcode scanner can be selected. Barcodes are printed on the visitor list. After the interviewee signs, the visitor will automatically scan and sign out in the guard room, which is more efficient and faster.
For vehicles entering and exiting, a transparent plexiglass fixed box is placed behind the windshield of the car. Insiders only need to put the card in this box. When entering and exiting the vehicle channel, the card will be read by the antenna on the ground or next to it, and the barrier will automatically Turn on, and the camera will capture the vehicle at the same time.
The TV-type long-distance card used in the system can be used for long-distance recognition or short-distance recognition. Combined with the REV1 card reader with a reading distance of 15 cm, it can realize access control, attendance, consumption, visitors, elevators, vehicles, and patrols. More management and other all-in-one card functions. In addition, the remote proximity card also has the characteristics of non-copying, safe and reliable, and long life. The non-contact card reading method reduces the mechanical wear of the card to zero.
2. System implementation instructions
The system is equipped with a management server and placed in the computer room of the monitoring center; multiple clients are set up, and a monitoring client computer is placed in the lobby on the first floor for security personnel to view the personnel entry and exit photos and alarm information in real time, and install it on the computer room management server The one-card management software is responsible for the maintenance and management of the entire system; the access controller is the core component of the system, responsible for the processing, storage, and control of the input and output information of the entire system. In order to facilitate on-site construction and daily maintenance, the access controller is installed nearby Near the door point, all access controllers are connected via TCP/IP.
Install remote card readers and microwave human body detection probes on the corridor doors; the induction antenna is buried under the floor or placed on the ceiling, and an automatic door-type microwave human body detection probe is installed at the top of the door. Each employee is issued a remote sensor card. The person walks to the first few 3 meters to read the card, and then the door opens automatically after being detected by the probe. The door does not close unless all the personnel pass through, and all the personnel pass through the back door. The angle of the microwave probe is adjustable. The indoor walkway overlaps with the antenna sensing area. Area, set the microwave probe detection area to be about 60 cm, the door will not open when people do not enter the area when passing through the aisle to prevent accidental opening; for stair doors and fire passages, manual swipe card opening methods are used for entry and exit, and close reading is installed inside and outside. Card reader, employees enter and exit by swiping their cards; for visitors and outsiders contacting business, temporary cards are issued for management. Outsiders visiting need to register on the visitor machine at the designated location of the management department, and the registration staff will ask the visitor to go. After contacting and confirming by phone, issue a card with the corresponding authority and print the visitor form. The visitor can enter and exit the designated floor or department with the authorization card in his hand, and cannot enter or leave other unauthorized floors or departments. Hierarchical authority management realizes effective management of the security of the entire unit.
In order to achieve the regional anti-tailing function, in accordance with the strict requirements of the building’s safety management, this scheme uses two doors at the entrance of the first floor of the design unit building as anti-tailing passages. In order to meet the fire protection requirements, the fire alarm button is connected to the alarm input of the controller. When a fire alarm occurs, all doors connected to the control will be automatically opened. The network cable from each access control controller to the switch adopts Category 5e shielded twisted pair to ensure stable communication. Where 485 transmission is used, 485 line must also use RVSP shielded twisted pair. Shielded wires are used to connect the access control controller and other equipment at the door.
