ZR127 (A) Mining overhead passenger electric control device

1 Product Overview

The ZR127 (A) mining overhead passenger electric control device adopts an imported PLC programmable controller, and has two information display functions. One is the touch screen display of four interfaces: "operation interface", "parameter display interface", "fault display interface", "parameter setting interface", and can display information such as the operation mode, "status", "fault", and "data" of the overhead passenger device; Another option is to display interfaces such as "idle mode", "dot mode", "broadcast mode", "music mode", and "alarm mode" on the button display screen.
The use of PLC programmable controller and CAN bus communication not only saves tedious control circuits, but also enables more accurate, safe, and fast control of equipment operation and stop; By real-time monitoring of motor current, voltage, brake oil pressure, oil tank temperature, and reducer temperature, the safe operation of the motor, reducer, and hydraulic station can be effectively monitored; Through the audio bus, local and remote remote communication and security protection alarms can be achieved to improve the safety performance of overhead passenger devices.

2 Main functions and characteristics

2.1 Data collection function
2.1.1 Equipped with analog data acquisition and display functions such as driving motor current and voltage, reducer temperature, oil tank temperature, brake oil pressure, etc.
2.1.2 It has the functions of collecting, displaying, and alarming switch signals such as head offside, tail offside, uphill slope rope dropping, downhill slope point rope dropping, tension decrease, emergency stop along the line, anti rope detachment along the line, slip protection, brake action failure protection, and exit point prompt.
2.1.3 It has the function of collecting and displaying the running speed of the steel wire rope, as well as providing alarms in case of overspeed or underspeed faults.
2.2 Alarm function
2.2.1 It has an alarm function for analog signals exceeding the limit, such as fuel tank temperature, gearbox temperature, and brake oil pressure.
2.2.2 It has switch quantity alarm functions such as up (down) offside, emergency stop prohibition, leakage emergency stop, tension decrease, brake failure, etc.
2.2.3 Equipped with overspeed and underspeed protection alarm functions for steel wire rope operation.
2.2.4 After the equipment starts running, the signal control box along the tunnel will sound and light an alarm every 5 seconds to indicate "driving, no pedestrians".
2.3 Control functions
2.3.1 Equipped with PLC automatic control function, with three operating modes: continuous, intermittent, and maintenance.
2.3.2 It has protection functions such as head deviation, tail deviation, uphill slope rope dropping, downhill slope point rope dropping, anti detachment rope along the line, emergency stop along the line, decreased tension, overspeed, underspeed, slip protection, brake action failure, passenger distance too close, oil tank temperature exceeding limit, reducer oil temperature exceeding limit, brake oil pressure exceeding limit, motor current and voltage exceeding limit. After a fault occurs, the PLC control box disconnects the output and continuously alarms; At this point, the PLC program is locked and the electrical control device cannot be restarted. Only by troubleshooting and pressing the fault reset button can the lock and alarm be released.
2.3.3 It has an emergency stop and no start function.
2.3.4 Reserve a remote communication interface (Ethernet interface) for easy remote communication with the ground control center, remote management of operational information, and remote diagnosis of operational faults.
2.3.5 It has the function of delayed start of sound and light warning along the route, as well as the ability to coordinate and communicate with each other throughout the tunnel.
2.4 Display function
2.4.1 Display function of the control panel
The operation interface displays: the operation mode of the overhead passenger device (continuous, intermittent, maintenance), remaining time of interruption, simulated cycle operation light, high-speed brake (released), low-speed brake (released), operating speed, oil tank temperature, reducer temperature, brake oil pressure, working voltage and current of the driving motor.
Fault interface display: fault information such as head out of position, tail out of position, uphill rope dropping, downhill rope dropping, decreased tension, emergency stop area, anti rope slipping area, overspeed, underspeed, slip protection, brake action failure, passenger distance too close, CAN bus signal interruption protection, etc.
2.4.2 When there is a triggering signal from the sound and light alarm at the bend and exit point, it will emit the corresponding sound and light alarm.
2.5 Communication functions
2.5.1 Implement full tunnel voice communication and alarm voice for monkey car operation.
2.5.2 Implement real-time communication between on-site and ground remote landline telephones and mobile devices.
2.6 Information storage (black box) function
The operational data storage recorder, due to its large capacity data storage function, can store and record 30 days of operational information of the device, including safety protection information, alarm and start stop operation control information. The recorded information only has a reading function, and there is no legal person to modify or delete it, ensuring the validity, authenticity, and real-time nature of the data. Once an accident occurs due to equipment failure, the operating parameters of the entire equipment at the time of the accident can be identified, thereby identifying the cause of the accident; On the other hand, in the event of uncontrollable external disasters, the device is not easily damaged, so running a data storage recorder is called a "black box".
2.7 Remote monitoring and control function
The ground control room can remotely monitor and control underground equipment, provide parameter information, fault information, remote display of operating status, and remote scheduling and control management, achieving unmanned functions. The factory has reserved a remote monitoring interface.
