DESCRIPTION

Product use

Based on the national standard "Test method for aerodynamic performance of fan" and the coal industry standard "Test method for field performance parameters of main fan used in coal mine", the system uses industrial computer detection technology to continuously measure and process the running state of large fan used in coal mine. Various data on fan operation status are provided in a variety of ways.

Ensure the safe operation of the fan and facilitate the performance test of the fan, and provide convenient conditions for the expansion of various functions. Fan operation parameters for online measurement and processing include: static pressure at the fan inlet, total pressure, wind speed, flow rate, inlet temperature (i.e., underground gas temperature), bearing temperature of the motor, stator winding temperature, motor input voltage, current, speed, power and total power, fan efficiency, positive and negative wind signals, etc.

System composition

The monitoring system of main ventilator used in coal mine is composed of system control cabinet, upper computer and front-end acquisition sensor. The control cabinet adopts PLC as the control core to collect the operation data of electromechanical equipment, including voltage, current, closing and opening, fault, motor temperature (all motor bearing temperature and stator temperature are directly input into the PLC analog module through PT100), vibration, damper status, etc., as well as environmental parameters collection, including air volume, wind pressure, temperature, etc.

Main feature

Using high-performance imported PLC, the system reliability and anti-interference ability are guaranteed. The system has remote control, local control, automatic control, manual control and other functions.

The transmission of the system from the control site to the host computer is a digital signal, so it has a far transmission ability and a high anti-interference ability.

The system can monitor the environmental parameters such as wind speed, air volume, negative pressure, pressure, differential pressure, temperature, damper switch, etc., and can also monitor the parameters of fan equipment and voltage, current, power, electricity and other parameters;

Powerful programming function, simple and practical, to achieve detection, alarm and control functions;

The system has access to the LAN and data upload functions. All terminals on the LAN can check all data of the system (including dynamic graphs and reports) under authorization.

The system is equipped with bus interface, which can realize data communication with host computer or other PLC easily through 485 communication protocol.

It has the function of displaying the interlocking starting and stopping information of the fan. Real-time curve graphics display the online measurement and processing of fan operating parameters, easy to observe the change trend of different parameters within one hour (or other specified length);

Configure dynamic graph related parameters: analog data display, bar chart, the on-off state of the equipment is represented by GIF animation and linear animation, the working state of the sub-station (fault and normal), the cumulative time and number of on-off of the equipment;

Cloud monitoring and mobile APP and other functions.
