one. On-line electronic patrol system: integrated wiring is performed within a certain range. The patrol inspection device is set on a certain patrol inspection point. The patrol inspection personnel only needs to carry an information button or an information card, according to the wiring. The scope of the patrol, the manager simply in the central monitoring room can see the patrol patrol personnel in the patrol route and the arrival of the patrol inspection time. Its disadvantages are large amount of construction and high cost, and the outdoor installation of transmission lines is subject to human damage. It is even more difficult to reconfigure an online patrol system for a renovated building. Also easily affected by the temperature, humidity wiring range, installation and maintenance is also cumbersome, the advantage is real-time management, but it can easily lead to system failure crashes;
two. Off-line electronic patrol inspection system: As the name implies, this system does not need wiring, as long as the patrol inspection point is installed in the patrol position, patrol personnel holding the patrol inspection device to each patrol inspection point to collect information, the information passed The data line is transmitted to the computer, and the entire patrol inspection process can be displayed (if it needs to be printed by the printer, a complete patrol inspection inspection report is formed). Compared with online electronic patrol inspection system, the disadvantage of off-line electronic patrol inspection system is that it cannot be managed in real time. If there is a walkie-talkie, this shortcoming can be avoided and real-time alarm can be realized. At the same time, according to the product can be photographed. The function can be more able to leave pictures of accidents at the first time, combine three points, and ensure timely and safe handling of emergencies. Its advantages are no wiring, simple installation, easy to carry, easy operation and reliable performance. Not affected by temperature, humidity, and range, system expansion, line change is easy and the price is low, and should not be destroyed. The system is easy to install and maintain and is suitable for any patrol or duty inspection field.
The following are the patrol comparison items, and they are more intuitive to understand the difference:
Compare items
Online patrol
Offline patrol
installation
Complex installation, wiring, power supply, network
Easy to install, no wiring
Equipment cost
Use more equipment, high system cost
Low system cost
system maintenance
It is difficult to ensure the normal and long-term operation of the system. Any line and equipment problems require the supplier to solve the problem.
Easy to maintain, similar to the patrol point and other simple issues can be resolved on their own
real-time
The patrols of patrolling officers can be seen on the control center computer in real time, but few units are actually used from time to time and can easily cause system crashes.
You need to download to the computer to see the patrol report, but if you have a walkie-talkie, you can avoid this shortcoming
Comparison project online patrol offline patrol installation and installation complex, need wiring, power supply, network installation is simple, no wiring equipment costs to use more equipment, system cost is high system cost is low system maintenance and protection system is normally difficult to run for a long time, there are any lines and The equipment problem requires the supplier to come to the door to solve the problem of maintenance and convenience. Similar problems such as changing the patrol point can be solved by the property itself. The real-time nature of the patrol can be seen on the control center computer. However, few units are actually used at all times. , And it is easy to cause system crashes to crash. You need to download it to the computer to see the patrol report. However, if you have a walkie-talkie, you can avoid this disadvantage. Conclusion Due to simple installation, low equipment cost, and easy maintenance, most customers have already taken offline. Patrol;
Another note <br> <br> works is simple: no borehole, no wiring, the entire amount of the project is to patrol without any connection point (information button) fixed in position on patrol, as long as the entire process to ensure a fixed point The firmness, no other technical requirements. The project can also be carried out after the community (factory) intelligent system has been fully completed. Easy to use.
project
Inductive Patrol
Contact Patrol
Operational
Near the patrol and sensing point can read information, easy to read
The patrol stick and the information button must be in close contact with each other to read the information. It is inconvenient to operate.
Patrol
Chinese shows that it is possible to interpret the card time and read card success information
Without LCD, it is difficult for the user to know if the time is inaccurate or the reading is not successful;
Patrol point
Wall-mounted installation, anti-theft, anti-theft, strong adaptability, free from environmental impact
Exposed metal enclosures are prone to poor contact due to contamination and need to be replaced in a short time. They are greatly affected by the environment.
communication
Direct communication with the computer via RS232 serial port, convenient, fast download speed
Must be equipped with a dedicated cradle to communicate, increase costs and failure links;
Rework Comparison
Non-contact card readers, low repair rates for patrols and sensors
Security guards often attack the information button with a patrol stick, resulting in extremely high repair rates;
The project patrol contact patrol operation patrol and the proximity point can read information, read the convenience patrol stick and information button must be very accurate contact to read the information, the operation is very inconvenient;
The Chinese patrol display shows that there is no liquid crystal for reading card time and card reading success information, and it is difficult for the user to know when the time is not correct or the reading is unsuccessful;
The patrolling point can be installed in the form of wall-mounted, anti-theft, anti-theft, and strong adaptability. The metal shell exposed to the environment is prone to bad contact due to pollution, and it needs to be replaced within a short time. It is greatly affected by the environment.
Communication directly communicates with the computer through the RS232 serial port, which is convenient, and the download speed is fast. It must be equipped with a dedicated cradle for communication to increase costs and failures.
Rework compared with non-contact readers, low repair rate of patrols and sensing points, security often patrol sticks strongly hit the information button, resulting in extremely high repair rate;
Conclusion: The contact patrol has gradually been eliminated due to its high failure rate and large maintenance investment. Inductive patrols will become the mainstream in recent years.
