Abstract
The invention relates to a power system monitor. The monitor is provided with a collector, a memory, a comparator and a controller; the collector is used for acquiring a signal of an outside image and transmitting the signal to the comparator; the memory is used for storing a picture signal which is in a normal state; the comparator is used for comparing the signal with the signal stored in the memory after receiving the signal of the collector, and outputting the compared result to the controller; the controller is used for receiving the compared result information of the comparator, and outputting the identifying signal to a display and a loud speaker. With the adoption of the monitor and method provided by the invention, workers can know whether abnormal situation exists through the alarm sound without monitoring each display in the control area; and the substation site can be monitored in real time, the potential safety hazard can be reduced; and meanwhile labor force is saved and cost is reduced.
Description
Technical field
The present invention relates to a kind ofly can keep watch on the method for monitoring that exterior object moves, relate in particular to a kind of electric system monitor and method for monitoring that can improve defencive function, belong to the Electric Application field.
Background technology
Some equipment in power transformation place are often lost because of lawless person's theft.And some power transformation place can not in time be found after the device losses because remote, stays serious potential safety hazard for the operation of electric system.Monitor of the prior art generally includes video camera and display, and whether there are objects moving in order to keep watch on the outside, needs the staff and keeps in that display is other always and keep watch on.
Summary of the invention
The present invention is directed to the problem that exists in the above-mentioned prior art, a kind of electric system monitor is provided, solved the problem that monitor of the prior art needs Attended mode.
Another object of the present invention is to provide a kind of method for monitoring of electric system monitor.
Technical scheme of the present invention is following:
Be provided with collector, gather the signal of external image, and signal conveys is arrived comparer;
Be provided with storer, the picture signal of storage normal condition;
Be provided with comparer, behind the signal of reception collector, compare with signal stored in the storer, and comparative result information is exported to controller;
Be provided with controller, receive the comparative result information of comparer, will judge that signal exports to display and loudspeaker.
Method for monitoring of the present invention comprises the steps:
Collector is transported to comparer with the external image signal that collects;
Comparer compares the external image signal that receives and the current picture of memory stores, if coming to the same thing relatively then is identified as same frame; If inequality, it is unusual then to be identified as picture; And comparative result exported to controller;
Controller receives the comparative result information of comparer, and object information is judged, if judge abnormal signal, then abnormal information is exported to display and loudspeaker, carries out image and audible alarm.
Advantageous effect of the present invention is following:
The staff need not keep watch on each display in the control area, but just can know whether have unusually through warning tones; Can keep watch on the power transformation place in real time, reduce potential safety hazard, save manpower simultaneously, reduce cost.
Description of drawings
Fig. 1 is a formation block diagram of the present invention.
Embodiment
Following with reference to accompanying drawing, in conjunction with embodiment the present invention is described in detail as follows.
Embodiment
Be provided with collector, gather the signal of external image, and signal conveys is arrived comparer;
Be provided with storer, the picture signal of storage normal condition;
Be provided with comparer, behind the signal of reception collector, compare with signal stored in the storer, and comparative result information is exported to controller;
Be provided with controller, receive the comparative result information of comparer, will judge that signal exports to display and loudspeaker.
Method for monitoring of the present invention comprises the steps:
Collector is transported to comparer with the external image signal that collects;
Comparer compares the external image signal that receives and the current picture of memory stores, if coming to the same thing relatively then is identified as same frame; If inequality, it is unusual then to be identified as picture; And comparative result exported to controller;
Controller receives the comparative result information of comparer, and object information is judged, if judge abnormal signal, then abnormal information is exported to display and loudspeaker, carries out image and audible alarm.
In the described comparer comparison step,, then store current picture, continue to carry out repeatedly picture then relatively if picture is identical; If its picture is inequality, then import warning message to controller with continuous communication.
Claims (3)
1. electric system monitor is characterized in that comprising following parts:
Be provided with collector, gather the signal of external image, and signal conveys is arrived comparer;
Be provided with storer, the picture signal of storage normal condition;
Be provided with comparer, behind the signal of reception collector, compare with signal stored in the storer, and comparative result information is exported to controller;
Be provided with controller, receive the comparative result information of comparer, will judge that signal exports to display and loudspeaker.
2. the supervision display packing of electric system monitor according to claim 1 is characterized in that comprising the steps:
Collector is transported to comparer with the external image signal that collects;
Comparer compares the external image signal that receives and the current picture of memory stores, if coming to the same thing relatively then is identified as same frame; If inequality, it is unusual then to be identified as picture; And comparative result exported to controller;
Controller receives the comparative result information of comparer, and object information is judged, if judge abnormal signal, then abnormal information is exported to display and loudspeaker, carries out image and audible alarm.
3. the supervision display packing of electric system monitor according to claim 2 is characterized in that if picture is identical, then storing current picture in the described comparer comparison step, continues to carry out repeatedly picture then relatively; If its picture is inequality, then import warning message to controller with continuous communication.
