The Practical Significance of Electronic Patrol Management System
The electronic patrol management system is an essential system in security, because no electronic technical protection equipment can replace security, and security is the most important security protection work is patrol.
The electronic patrol management system can effectively manage the security patrol work and is listed as an essential item in the security system in developed countries in Europe and the United States and China.
The 24-hour non-stop patrol has become a selling point for many real estate developments. The selling point needs to rely on the electronic patrol management system to supervise and guarantee. And the electronic patrol management system is the security system with the least investment and the highest efficiency.
Electronic Patrol Technology Type Online Electronic Patrol
The electronic patrol system entered China from the 1990s. It is broadly divided into two categories: an online patrol system and an offline patrol system.
Online electronic patrol is to conduct integrated wiring within a certain range. The patrol device is set on a certain patrol point. The patrol personnel carry information buttons or information cards and patrols according to the scope of wiring; the manager only needs to The central monitoring room can see the patrol route where the patrolling personnel are located and the time of arrival at the patrol point. If the patroller has an accident and does not read the card, the center can quickly check and handle emergencies. Since the on-line type can realize real-time control, it is more appropriate to use an on-line system in places where patrol requirements are particularly strict or patrol work is dangerous. In addition, an online patrol system can also be used in combination with access control wiring in a community or management area where there are many access points.
However, its disadvantages are large construction volume and high cost, which are easily affected by temperature, humidity, and wiring range. It is also troublesome to install and maintain, and it is also difficult to reconfigure a renovated building. Outdoor installation of transmission lines is also vulnerable to human damage.
Offline Electronic Patrol
In view of the above shortcomings of the online patrol system, by the mid-to-late 1990s, some manufacturers introduced an offline patrol system. Compared with on-line type, this method has the advantages of being easy to carry, no wiring, simple installation, not affected by temperature and humidity, and not easy to be destroyed. This solves the problem of expensive investment, and realizes system expansion and line change. It's easier. Once the products were popularized, they were very popular among users. At present, off-line patrols have become mainstream products in the domestic market and occupy about 90% of the market share. Offline patrol system is divided into contact and inductive.
Contact patrol system
The contact patrol system, also known as the information button patrol product, utilizes TouchMomery technology and IButton technology from DALLAS, USA. The working procedure is to install the information button (also called Ibutton, TM card) at the patrol point. When the patrol personnel patrol, they hold a patrol machine (or called a patrol stick) to each point and touch the information button. The patrol machine reads the information button data. After completing the entire patrol mission, to the monitoring center, the management personnel will transfer the information stored in the handheld patrol machine (stick) to the computer through software, analyze the patrol data and generate a printed report for inspection. The advantage of the TM card is that its number is the only one in the world, free from electromagnetic interference, and there is no error in reading; In addition, it has solid physical properties, is not afraid of rain and snow, is resistant to high and low temperatures, and is superior in corrosion resistance. It is generally suitable for use in harsh environments. .
However, due to the "contact" of such a system, some drawbacks are revealed: First, the patrol (patrol stick) and the information button must be in close contact with each other to read information, which is inconvenient to operate, especially at night. , The light is not good, not easy to identify; Second, the exposed metal shell of the information button is vulnerable to contamination, resulting in poor contact, resulting in failure to effectively collect information; Third, the exposed information button is easily destroyed.
Wang Jingcheng, marketing manager of Shenyang Jinwanma Hi-Tech Development Company, said: “Some people still have incorrect understanding of the patrol system and believe that the use of this system is a mistrust of security personnel. Therefore, the patrol system is treated as It is a 'tool for managing security'. "Therefore, incidents of deliberately destroying information buttons occur from time to time, which puts higher requirements on the reliability and stability of the patrol system. In recent years, patrol bolts have been widely used in contact systems. They can push information buttons into the wall, thus solving the problem of lost and destroyed.
Inductive Patrol System
Inductive patrol system is mainly the application of radio frequency identification technology (RFID) in patrol system. Its advantage is that there is no need to touch the information button when reading data: When the patrol personnel arrive at the patrol point, as long as the patrol machine is close to the information button, the patrol machine can automatically detect the information point information and automatically record it. . Since the read button does not need contact, the patrol button can be embedded in a concealed object, such as a wall, so that people with ulterior motives cannot know the location of the tour, and fundamentally solve the problem that the information button is destroyed. At present, inductive products have become the mainstream in the patrol market, accounting for about 70% of the proportion.
On the other hand, there are certain defects in the induction type. For example, if the communication distance is too short (about 5cm), it is still inconvenient for patrollers to search for patrol points when the light is not good in the evening. In addition, the inductive type uses sensing technology to read information and is susceptible to electromagnetic interference. There are certain limitations in application in some harsh special environments.
For this reason, in the near future, radio frequency identification (RFID) technology will show its full potential in long-distance communications. According to industry insiders, the effective communication distance of induction electronic patrols can reach 2 to 10 meters in the next two to three years. At the same time, the recorded information also includes the information of patrol personnel arriving and departing from each patrol point. Therefore, it is possible to fully grasp the patrolling situation of the patrolling personnel and is more conducive to the management of the patrolling personnel.
In addition, after using RFID technology, patrol personnel will report patrol data more quickly after work. In one minute or so, the information transmitter can collect all the information in 10 or 20 patrol machines at the same time. The technology of this long-range electronic patrol system greatly exceeds the old-style contact electronic patrols and proximity-sensing electronic patrols and will become a new generation of products.
Future trends
Although the electronic patrol has always been a relatively small project (the share of security projects is about 1%), but in recent years, the market sales show that this is a steady increase in the market. This also makes a lot of manufacturers in the product and technology applications have been greatly improved and improved.
