The access management of subway construction sites has always been a difficult problem. Imagine a shaft, the daily access of construction workers and the identity information of relevant personnel. Managers hope to understand and master the following information in the shortest possible time:
1. Has anyone entered the well?
2. The number of specific construction workers underground?
3. Identity information of underground construction personnel (managers, guests, construction personnel, supervisors, illegal personnel)?
4. Who are the illegals? Snapshots, alarms and real-time video recordings in and out?
5. The specific time when the underground construction workers enter and exit?
Traditional solutions may be to use time attendance machines, surveillance, fingerprints and barriers. However, the problems of these systems are obvious: the speed of the fingerprint system is a problem when searching for one to several thousand, and there are unsanitary, high rejection rate and misrecognition rate; the attendance machine cannot control the outsiders, and there are generational problems. The problem of swiping cards; the speed of the barrier system is relatively slow, there will be long queues, and it is obviously not humane enough. However, since the monitoring system cannot be truly linked with the management system, a lot of manpower is needed to prevent it beforehand, and it can only play the role of post-event verification, and the value is greatly discounted.
There has never been a perfect solution to these seemingly basic and simple problems, and everyone seems to have become accustomed to it for so many years, until the fast barrier-free channel was finally developed and successfully applied.
The open intelligent channel at the entrance and exit of the shaft integrates functions such as LED screen display system and camera monitoring, so that the information of the underground construction personnel can be grasped at any time. It plays an active role in the information management and safety management of the underground construction personnel in the construction unit. Barrier-free passage, there are no obstructions between passages, and accidents can be quickly evacuated.
The main function:
Illegal foreign personnel alarm function: When foreign personnel or other personnel with cards but not authorized to enter the well pass through the channel, the channel will emit sound and light alarms, and at the same time, the video data of the passing personnel will be captured and recorded in real time. Effectively prevent the entry of foreign personnel.
Fast passing function: During the peak of going up and down the well, the passage can pass more than 100 people per minute, and there will be no congestion. Since there are no obstacles, unforeseen circumstances do not affect evacuation.
Real-time display: When the construction personnel pass through the channel, the number of underground construction personnel and other relevant information can be displayed in real time on the LED display.
Two-way entry and exit, automatic direction recognition: each channel can be entered and exited, which greatly improves the utilization rate of the equipment. When people pass through, the system will automatically identify the entry and exit directions, providing managers with more accurate data and preventing them from leaving immediately after swiping the card.
Automatic statistics function: The personnel in charge of construction management do not need to manually count and go down to inquire about the number of construction personnel and the information of specific down-hole personnel. They only need to inquire through the computer, analyze the credit card records of the construction personnel, and automatically generate a list of people who have not gone down. Save manpower and time and improve work efficiency.
Preventing swiping cards: For each person passing through, the system can only recognize one card, which effectively prevents the phenomenon of swiping cards instead.
Support “anti-infiltration”: If the construction personnel hand over the card to others to enter again after entering, the system will automatically alarm.
24-hour surveillance video recording function: The system can monitor the personnel passing through the channel for 24 hours. Not only can the information of the passing personnel be recorded on the video synchronously, but also the relevant detailed information of the person will be displayed when the video is played back.
Remote monitoring function: The system supports the remote monitoring function, and the leaders in charge can directly conduct remote video monitoring in the office, and summarize the statistical reports of the construction personnel entering and leaving the day, which improves the real-time management.
At present, the system has been widely used in Beijing Yizhuang, Daxing Line, Line 4, Line 6, Line 8, Line 9, Line 10, Line 15, etc.
