In described control box, if operating personnel find that when mounted the signal number of detecting unit is less than the processor input interface of reservation during system, can locate wire jumper input signal terminal row, to this processor input pin input high level (being set to 1) that has more; When if operating personnel find the processor input interface of the unnecessary reservation of detecting unit signal number, the detecting unit signal that can will have more at input signal terminal row place (logical relation: with) in parallel with the signal that is close to has guaranteed the extended capability of system.
Described audible and visual alarm device is arranged on the scene, hazardous location, comprise drive circuit board, stand by lamp and alarm loudspeaker, described drive circuit board is connected with the alarm loudspeaker with stand by lamp respectively, and described audible and visual alarm device sends audible and visual alarm after the signal of the processor output that receives control box.
Described temporald eixis lamp is arranged on the pulpit, and during to invasion, control box can be controlled the pilot lamp of correspondence and light, and informs the orientation that the operator on duty invades when on-the-spot any one orientation detection.
The method of work that a kind of Intelligent region break alarm system adopts mainly comprises the following steps:
Step (1): lay traversing carriage in the hazardous location; Photoelectric sensor is installed on traversing carriage;
Step (2): system powers on, and the processor of control box is started working; Judged whether the invader;
Step (3): if judgement has an invader, control box processor can send signal to audible and visual alarm device and temporald eixis lamp, the audible and visual alarm device sends the voice signal of alarm, the temporald eixis lamp is pointed out the position of hazardous location, invader place simultaneously.
Described step (2) step is as follows:
Step (2-1): after starting working, if do not invade, all 4 input signals are all high level, and processor reads the signal that receiver is inputted into always; All output pins of simultaneous processor (Out1, Out2, Out3, Out4, Out5) are all high level;
Step (2-2): when invasion occured, the one or more meetings in all 4 input signals became low level, and processor can keep the state of all input signals;
Step (2-3): processor becomes low level with output pin Out5 output signal by high level set, the work of audible and visual alarm device; Judgement is which is input as low level simultaneously, and the output signal of correspondence is become low level by high level set, the corresponding output pin Out1 of input pin In1, and the corresponding output pin Out2 of input pin In2, the rest may be inferred, and corresponding temporald eixis lamp is bright; The operator on duty is by the orientation of the state judgement invasion of pilot lamp;
Step (2-4): it is constant that system will keep the middle state of step (2-3), until processor receives reset signal; The operator on duty checks the zone, after determining dangerous the removing, presses reset button, and native system namely resets;
Step (2-5): after processor receives reset signal, all outputs are set high level, orientation, left and right pilot lamp goes out, and the audible and visual alarm device quits work;
Step (2-6): normal monitor state is got back to by system, reads input signal, circulates with this.
The principle of work of native system:
Under normal condition, receiver can receive the light signal of the transmitter of photoelectric sensor always, to processor output high level.When invasion occured, light was blocked, and the receiver signal becomes low level by high level; This moment, processor sent signal to the audible and visual alarm device, and audible and visual alarm device response alarm the invader withdraw from, and the temporald eixis lamp that simultaneous processor is controlled the correspondence in the pulpit according to the numbering of sending the receiver of signal (be input pin number) is lighted.
The beneficial effects of the utility model:
1) framework is simple, controls reliable, easy to implement;
2) adopt portable detecting unit, but the flexible arrangement surveyed area; The installation traversing carriage is adjustable, affected by ground flat degree little, is easy to arrange;
3) receiver adopts particular design, is not subject to the light source impact of external environment;
4) input signal can be expanded with the mode of parallel connection, can increase arbitrarily detecting unit quantity, and opening is good, extendability is strong;
5) detecting unit is carried out azimuth coding, can show the orientation of invasion;
6) system adopts high level as normal signal, follows the fail safe principle, has prevented that effectively reliability is high because line fault causes thrashing.
