The typical case – the function of integrated automation system:

The realization the function of A three machine automation along the working face:

●centralized control, the local type, start the crusher, reversed loader, conveyor according to the reverse sequence , stop and start according to the sequence, stop time interval can be adjusted; maintenance mode can achieve single local stop three machine on the spot.

●can monitoring and query three machine stop state, showing three engine start-stop animation, three engine start-stop light alarm ( light alarm can be set in the head of equipment) fault information in a real time, and can be uploaded information statistics.

●reliable safety emergency stop circuits (software and hardware to realize monitoring) , can stop the three machine timely and accurately when find the fault , can accurately report the emergency stop position.

●arranged the special coupler near the working face controller and effective coupling with the scheduling program-controlled telephone, effective breakthrough along the playback if the phone with no one to answer, realize the reliable communication and scheduling along the line.

Realization the function of trough belt automatic:

●one button to start the equipment according to the logic of the frequency transformer switch under the centralized control, the local type, accept the return signal, health signal of the frequency transformer.

●can accept and monitor the state information of the frequency transformer by contact or MODBUS communication protocol, and upload the received information to the underground ring net switch, then can communicate with the upper computer on the ground.

●reliable and safety circuit, can stop the belt accurately and timely when found the malfunction and can report the emergency stop position accurately.

●can effectively realize the trough belt and working face three machine equipment chain, the trough belt not start and three machine on the working face not allow to start the operation under the centralized control, the local type, can cancel the equipment chain under the maintenance mode, a reliable guarantee for the safe operation of equipment.

●set special coupler near trough crossheading controller, and effective coupling with scheduling program-controlled telephone, effective breakthrough along the playback when the phone with no one to answer, and realize the reliable communication and scheduling communication along the line.

●heads set voice and light alarm telephone, the effective realization of voice and light kinds of two alarm.

●belt various complete protection and integrated in the control line, closely linked with the belt control, can set the delay, alarm, alarm parking.

The typical case – the function of super- long belt communication control system :

Control system:

●controlled equipment operation rate statistics and display

●controlled equipment operation state graphics, animation display

●controlled equipment operation state and Chinese characters display

●the emergency shut-off lock position display along the belt

●circuit breaker detection and circuit breaker position display along the line

The control mode of belt start and stop, emergency stop:

●belt machine start, stop control (including a single open, a single stop, interlocking start-stop)

●central control and local control mode to realize a sequence start of several belt conveyors

●maintenance control mode, break the chain relation under the several belt control, each belt machine can start alone

●inching control to achieve a single motor to move

●the emergency shut-off lock, pull the emergency cable to along the belt

Belt start and stop, emergency stop warning / alarm:

●belt machine starting Chinese Mandarin warning ( can be set number ), the sound intensity of 107 DB

●emergency shut-off lock Chinese Mandarin alarm along the belt, sound intensity of 107 DB

●belt machine overload alarm in Mandarin / English

●belt machine protection alarm English/Mandarin ( you can set options: alarm, shutdown, alarm and shutdown )

crossheading, roadway belt protection:

●belt deviation, coal piling, smoke, temperature, less speed, over speed, sliding, over-temperature sprinkling water, longitudinal tear protection, display speed and temperature value of belt machine in a real time, other protection tips with text and animation

●can be arranged the delay voice alarm along the line when machine protection acting

●can setting the belt stop or not by program or parameter according to the actual situation when belt machine start protection action

Voice call function:

●clear voice communication function, voice communication mode is half duplex, sound intensity is not lower than 107 DB, guarantee without blind zone along the working face

●can make 8 hours talk after power cut

Flexible connector connection mode:

●cable, telephone use stainless steel quick connector, U type pin connection( the grade of protection is IP67 )

Signal detection:

●all the testing input signal: switching, analog (1~5V; 4~20mA; 200~1000Hz) set selection by the parameter or program

●reservation with two RS232\/485 serial interface, and realized the seamless connection with all coal mine monitoring system (have essential openings)

The control of logic parameter adjust at anytimes:

●the controller have all adjustment parameter of detection and control function or the program adjustment function on-site

●password protection function when adjusting the parameters

The typical collection—the function of typical working face communication control system:

Control system:
