[0016] In view of the problem that the existing high plan screen 9 lacks monitoring during use and cannot play the material screening function of the high plan screen 9, this solution proposes a monitoring and protection device for the high plan screen 9 based on a real-time bus. The monitoring box 12 is connected to the cable 2 through the junction box 3 with a position switch 4, a positioning sensor 6 and a thermal resistor 8, wherein: the position switch 4 is used to monitor the vibration and shaking of the high plan screen 9, and the high plan screen 9 is shut down in time when the maximum shaking exceeds the maximum shaking; the positioning sensor 6 can sense the turning radius of the high plan screen 9, and the detected turning radius can be compared with the normal operating radius value of the high plan screen 9 to analyze whether there is any abnormality in the real-time operation of the high plan screen 9, so as to correct the operating posture of the high plan screen 9; the thermal resistor 8 can sense the temperature of the main shaft 11 of the eccentric device to avoid overheating of the main shaft of the eccentric device, thereby affecting production safety.

[0017] Furthermore, the monitoring box 12 is provided with a controller, a temperature monitoring module, an analog quantity collection module, a remote communication module and a display screen.

[0018] Through this technical solution, the controller uses a dual-core controller with a main frequency of up to 1GHZ, supports CAN, RS485, modbus_tcp, EtherCAT protocols, 40-channel digital input and output, and realizes cluster and grid-connected control through an expandable remote IO module; the temperature monitoring module is electrically connected to the thermal resistor 8 for data interaction to complete temperature monitoring, alarm and protection; the analog quantity collection module is used to receive the positioning sensor 6 signal and transmit the signal to the controller for processing, calculate the real-time circular motion radius value of the high square screen 9, and use this real-time radius value to compare with the normal operation radius value of the high square screen 9 to analyze whether there is an abnormal situation in the real-time operation of the high square screen 9; the remote communication module is used to connect the controller, the temperature monitoring module and the analog quantity collection module, and communicate with each other through the network, and at the same time, it can exchange data with the computer in the central control room through the external network cable for remote monitoring; the touch screen is used to display the operating status of the high square screen 9 on site, and the parameters of each switch and sensor of the high square screen 9 are displayed on the screen. It is used for displaying the running track of the high square screen 9, the shaft temperature alarm, and the limit position protection alarm, and the alarm information is stored for statistics and reference during the next maintenance.

[0019] Furthermore, two groups of thermal resistors 8 are provided, and the two groups of thermal resistors 8 are respectively installed on the bearings at both ends of the eccentric device main shaft 11.

[0020] Through this technical solution, the thermal resistor 8 is installed on the bearing seats at both ends of the eccentric device main shaft 11), and the temperature of the bearings at both ends of the eccentric device main shaft 11 of the high square screen 9 is detected, and the measured temperature data is transmitted to the temperature monitoring module, and finally to the controller.

If the sway radius of the high plan screen 9 is greater than the maximum sway radius during operation, the position switch 4 cannot detect the horizontal disc 5, and the output contact of the position switch 4 changes from a normally closed output to a normally open output signal, and the signal is transmitted to the dedicated controller of the monitoring box 12 of the high plan screen 9. This generates an alarm and a shutdown signal for the high plan screen 9 equipment failure, which ensures the safe operation of the high plan screen 9.

[0025] Working principle: the monitoring box 12 is connected to the cable 2 through the junction box 3 with a position switch 4, a positioning sensor 6 and a thermal resistor 8. The position switch 4 is used to monitor the vibration and shaking of the high plan screen 9, and the high plan screen 9 is shut down in time when the maximum shaking is exceeded; the positioning sensor 6 can sense the turning radius of the high plan screen 9, and the sensed turning radius can be compared with the normal operating radius value of the high plan screen 9 to analyze whether there is any abnormality in the real-time operation of the high plan screen 9, so as to correct the operating posture of the high plan screen 9; the temperature of the main shaft 11 of the eccentric device is sensed by the thermal resistor 8 to avoid overheating of the main shaft of the eccentric device, which will affect production safety, so as to better play the material screening function of the high plan screen 9, ensure the safe operation of the equipment, and achieve better use effect.
