Electronic Patrol System Technical Classification

First, the classification of electronic patrol system: electronic patrol system is divided into offline and offline. The online electronic patrol system is a real-time monitoring system composed of a data collector and a control room computer installed on the equipment site through integrated wiring. When the inspector carries the information button or information card and conducts inspection according to the wiring range, the manager can see the patrol route of the inspector and the time of arrival at the inspection point in the central monitoring room. Important occasions and some special requirements The device inspection can use an online electronic patrol system. The biggest advantage of the online system is that it can be managed in real time. The offline electronic patrol system is widely used. The biggest advantage is that no wiring is required. As long as the patrol information button is installed at the position to be inspected, the patrolman's handheld data collector automatically transmits information to each patrol point when collecting information. Computer and show the entire inspection process. Offline electronic patrol systems are available in contact and non-contact.

(1) Contact system. When the contact patrol inspection system reads the information, the data collector must touch the information button to automatically record the information such as the device position, contact time, and patrol personnel name represented by the information button into a piece of data. Light reminds that the early appearance of electronic patrol products is mainly contact type. With the rapid development of induction technology, contact systems have been used less frequently due to low market demand, high price, and inconvenient operation.

(2) Non-contact system. The non-contact patrol inspection system, also known as the inductive system, uses induction technology to read information within a certain range without touching the information points. The disadvantage is that it is susceptible to strong electromagnetic interference and should not be bad. When the work continues in the environment and there is strong electromagnetic interference at the production site, it is not appropriate to use a non-contact system. Non-contact systems require large quantities and low prices. Information buttons can be buried in walls and are not easily damaged by humans. This is the main method currently used.

Second, the working principle of offline electronic patrol system

After the inspector arrives at the equipment inspection point according to the set route and time, he only needs to slap the data collector at the inspection point (information button) and press the record button. The inspection rod memory records the inspector's arrival. Information about the time, location, and device code of the device.

If the patrol is not performed according to the normal procedure, the time is advanced or pushed back, the management software automatically determines that the patrol record is invalid.

Each button has a 12-digit l6 serial number that has been registered at the factory. The serial number is unique and cannot be changed, so it is easy to distinguish different information buttons. After each patrol is completed, the patrol record is transmitted to the computer, and the system management software can display the route patrolled by the patroller and the time of arrival at each patrol point. The management software can also automatically discover missed inspection points and generate inspection reports. The management center can inquire about relevant information at any time, and analyze and deal with the problem of dereliction of duty such as missed inspection.
