In the production run of large enterprises such as iron and steel, mine, often use long band conveyor.In the use, when accident takes place, should cut off general supply as early as possible, for this reason, need a plurality of signalling means are set on whole conveyor, but wherein one section signalling means break down, just need to use remote signalling means, just make accident expansion cause unnecessary loss.And all fronts do not know whether to possess the start condition mutually yet.

(3) summary of the invention

The utility model provides a kind of and can confirm whether status of equipment possesses the start condition and can stop as early as possible completely when accident takes place at the deficiencies in the prior art, has the intelligent alarm controller of strong anti-interference performance, the low characteristics of circuit power consumption.

The utility model is achieved through the following technical measures.

This controller comprises CPU, power supply circuit, vibration and reset circuit, light emission drive circuit, warning driving circuit, (talk-back circuit), feedback circuit and the anxious control circuit that stops, wherein, CPU and power supply circuit, vibration and reset circuit, light emission drive circuit, warning driving circuit, talk-back circuit, feedback circuit and suddenly stop control circuit and be connected.

Power supply is made up of transformer, diode, electric capacity, inductance, regulator block and stabilivolt, finishes by bridge rectifier and the filtering of π shape.

CPU vibration and reset circuit are made up of electric capacity and resistance, are connected with the single-chip microcomputer standard.

Light emission drive circuit is made up of diode, resistance and triode, is the two-stage transistor drive circuit.

The warning driving circuit is made up of triode, resistance, diode and hummer, is the two-stage transistor drive circuit.

Described feedback circuit is made of relay, scram button, relay Control and Feedback signal, and lc circuit carries out filtering to feedback signal.

Feedback circuit is made up of relay, button, and button signal is exported to terminal.

Suddenly stop control circuit and be made up of relay, LC filtering circuit, relay signal is connected to CPU.

Many alarm controllers can be got in touch with into network shape.

The toggle switch that the utility model is provided with on CPU can be set the time of alarm; Power supply circuit is to be electrically connected transformer by the 220V city, carries out the filtering of π shape behind the bridge rectifier, by regulator block and stabilivolt burning voltage, removes alternating component by capacitor filtering, supplies with cpu power; The CPU output signal drives relay by the two-stage transistor circuit, and the drive hummer moves, luminous row is luminous; When control center sends cue, signal is delivered to CPU; Scram button is delivered to CPU by relay with signal, handle these signals by CPU, adopt CPU to be used to send instruction in the utility model and receive information, power supply is supplied with cpu power, oscillatory circuit is used for providing sequential to CPU, reset circuit is used as automatically reseting of CPU, light emission drive circuit is used to report to the police luminous, the warning driving circuit, be used to the sounding of reporting to the police, feedback circuit is used for sending out feedback signal to PLC, suddenly stops to give again when the parking control signal of control circuit when being used for production line broken down exported to the PLC control system CPU of controller.

The course of work: system begins self check earlier after sending electricity, and the light-emitting block on the panel is glittering, buzzer warning, and alarm controller enters holding state after the self check.After receiving the start cue; the pilot lamp flicker of light-emitting block; buzzer warning; reach preset time of fire alarming after; no scram button is pressed in the system; system enters normal operating conditions; the quiet standby of hummer; light-emitting block Chang Liang; the programmable controller of control center can start production line automatically according to the signal of system feedback; if occur unusual in the network; the staff can be equipped with controller on production line the place device emergency stop switch that pushes for emergency nearby, feedback signal will reach on the PLC opertaing device of control center immediately, and then control is shut down.

The utility model designs at the characteristics of factory industry automation equipment according to singlechip technology, electronic technology, have warning accurately and reliably, the design of easy construction, network type saved the construction material cost greatly, saved supporting with it Programmable Logic Controller I/O number of spots and cost, and has strong anti-interference performance, characteristics that circuit power consumption is low.
