Bus type integrated belt machine protection supervising device

Technical field:

The utility model relates to supervising device.A kind of integrated belt machine of more specifically saying so is protected supervising device.

Background technology:

Many materials, particularly mine are the coal of exploitation down, all finishes the conveying task by conveyor.Ensure the continuity of conveyor normal transport, must use the integrated belt machine protective device.

At present, domestic existing integrated belt machine protective device, complex structure, unstable properties, Installation and Debugging are inconvenience very, and concrete manifestation is as follows:

1, unstable properties

The electronic circuit of existing apparatus has adopted elements such as a large amount of integrated circuits, triode, diode, resistance, and the trouble point is many, misoperation, false alarm often occur, makes the conveyor can't normal and continuous operation; Sensor signal is a switching value, because the Minepit environment complexity, often switching signal is inaccurate, and false triggering happens occasionally.

2, installation and maintenance are extremely inconvenient

Main frame has 14 wiring horn mouths, with each sensor, control object (containing each extension set during the collection control) Y-connection, need 14 on cable (more than 40 of line), line also has tens of between inner each electronic circuit board, if main frame has fault, certainly will remove line when changing main frame or electronic circuit board, also make mistakes easily during very trouble, and connection.

3, communication distance is short

Because cable itself has resistance, transmission has certain decay to signal, and existing apparatus is not suitably handled; transmission range only (is difficult to realize centralized Control) about hundred meters; often serious because of signal attenuation, fault-signal can not trigger warning, can not play the protection supervisory function bit.

Just because of there being above problem; the user rests on symbolic use and deals with in the inspection just not at all surprising conventional device; thereby but can not report to the police when because who is unwilling to allow the normal continuous production of unwarranted fault effects fault being arranged conveyor is protected, this has just stayed hidden danger to safety in production.
