Elevator safety monitoring solution

First, the demand analysis:

With the development of society, the role of elevators has become increasingly important, and the reliability of its operation has received much attention. Therefore, the installation of elevator monitoring system has very important practical significance. It can play an important role in improving the service level of customers, ensuring passenger safety and reducing the repair time. The purpose of elevator monitoring is to strengthen the management of the elevator control system with minimum human resource allocation, provide a more intuitive, clear, accurate and stable monitoring of the elevator operating state, and thus provide multiple possibilities for equipment maintenance and fault diagnosis. Fully improve the working efficiency and safety performance of the elevator control system.

Second, the network topology:

Third, the program consists of:

The solution consists of an elevator car monitoring module, an elevator machine room monitoring module, a four-signal wireless transmission module, a database server, an application server, and a communication server.

The car monitoring module mainly monitors the parameters such as the hall door (floor door), the car door, the leveling floor, the upper limit position and the lower limit position;

The equipment room monitoring module mainly monitors parameters such as temperature, humidity, traction machine current, and brake limit of the equipment room;

The four-letter wireless transmission module is mainly used for transmitting information of the equipment room and the car monitoring module to the database server;

The database server is used to store monitoring data, and is used by the application service platform to read real-time status, backtracking process, and record alarm information.

The application server provides an application platform to provide users with B/S access methods. Property, maintenance, supervision, users, etc. can be accessed through the Internet , or can be accessed through 3G using mobile terminals such as smartphones and PADs .

The communication server is mainly used to notify the rescuer, the person in charge of the management unit, the supervisory department, and other related personnel by using the preset alarm information according to the short message.

Fourth, the program features:

Versatility: The system is universal, and it can be safely monitored by elevators of different brands from different manufacturers.

Stability: Stable and reliable, 24 hours a day, no personnel on duty.

Safety: As an independent monitoring device, it is isolated from the physical and optocoupler of the elevator control system.

Practicality: The fault alarm information is transmitted to relevant maintenance / rescue personnel in real time to ensure that the personnel in the faulty elevator are rescued in time.

Ease of use: Based on the B/S architecture, the client does not need to install software or upgrade and maintain, and directly uses the web browser to log in to the management interface to operate, which is convenient and user-friendly.

Traceability: After the elevator fails and an accident, it can read the operating status of the elevator before the failure, and provide objective and accurate data for the analysis of the elevator failure.

Flexibility: It can be transported by different network systems of the three major operators of China Mobile, China Unicom and China Telecom.
