Abstract
The invention discloses a method for distinguishing the truth of monitoring videos transmitted from a site and a device for distinguishing the truth of the monitoring videos transmitted from the site. The method comprises the following steps of manufacturing an A comparison code display plate and a B comparison code display plate which are used in a group; arranging a comparison code displayer on each of the two comparison code display plates, wherein comparison codes displayed in real time are same in format; placing any one of the A comparison code display plate and the B comparison code display plate in a place, where the comparison code display plate can be shot by a camera, of the monitored site; placing the other one of the A comparison code display plate and the B comparison code display plate in a monitoring room. According to existing clocks, decoders respectively select a storage address, and implement a refreshing operation every 2-30 seconds. The method and the device have the beneficial effects that when the device provided by the invention is used for distinguishing the truth of the monitoring videos transmitted from the site, once the monitoring videos are made false by lawbreakers, the comparison codes in a computer display screen and the comparison codes in an independent display are different, and a monitor can immediately judge that the monitoring videos go wrong; next, the monitor can implement inspection or prepare to call the police.
Description
Technical field
The present invention relates to the method and apparatus of monitoring, particularly relate to and differentiate the on-the-spot method and the device that transmit the monitor video true and false.
Background technology
In prior art, the region of guard key, storehouse, building, place all arrange video monitoring, and it is also more and more general that residential quarters, office building utilize video monitoring to carry out safety management.
Video monitoring has been the indispensable security means of society.
But some are had to the place of very high value, lawless people can spare no effort to enter by every means, and in order to enter these places, what first will solve is the problem that video monitoring cannot be reported to the police.
And in existing Video Supervision Technique, have following problem, allow lawless person have an opportunity to take advantage of:
One, assailant makes monitoring client picture be the pseudo-monitored picture of non real-time safe period of time by implanting the mode such as virus, wooden horse in monitoring computers or other equipment always, thus makes monitor staff can not learn the real situation in monitored site;
Two, assailant is the pseudo-monitored picture of non real-time safe period of time by taking the monitored picture making to be sent to monitoring client by certain technological means between the wired connection or wireless connections of camera and monitoring client, thus make monitor staff can not learn the real situation in monitored site, can not accurately early warning.
Above drawback is that people think always, and open question, and even to this day, the technology of having no has breakthrough.
Summary of the invention
The object of the invention is to provide a kind of differentiate method and device that the monitor video true and false is transmitted at scene for the deficiencies in the prior art, the present invention makes living comparison code display panel in two pieces of principles, wherein one piece is placed on monitored scene, being caught on camera camera lens takes among monitored picture, transfer back on the computer display screen of Control Room, another block is then placed directly in Control Room, two pieces of comparison code display panels change in time and the comparison code refreshed is the same, so the comparison code on supervisor sees on computer display screen that block plate, with the comparison code of this block plate being placed directly in Control Room, should synchronously change in time and change, such as, change to " 7C " from " 3A ", two boards changes to " 7C " from " 3A " simultaneously, this is normal.
Once be placed directly in the plate of Control Room, change to " 7C " from " 3A ", and that block plate on computer display screen still " 3A " constant, the displaying contents of two boards is different, and this just illustrates that monitor video that scene is transmitted has had problem.
The present invention is by realizing by the following technical solutions.
Implement a kind of method that the monitor video true and false is transmitted at scene of differentiating, comprise the steps:
S1, first manufacture A comparison code display panel and B comparison code display panel;
S2, then on A comparison code display panel and B comparison code display panel, arrange comparison code display, shown comparison code form is identical;
S3, then clock generator is set on A comparison code display panel and B comparison code display panel, two clock generators are adjusted to time synchronisation; Described clock generator export comprise second, minute, hour, the clock data on date;
S4, then on A comparison code display panel and B comparison code display panel, arrange comparison code memory, the kind of comparison code is no less than 127 kinds; Comparison code order in each memory cell described is deposited, but A comparison code display panel is identical with the comparison code in the identical address in two comparison code memories on B comparison code display panel;
S5, then storage address decoder is set on A comparison code display panel and B comparison code display panel; Clock data is input to storage address decoder, according to present clock data, a storage address chosen by decoder, and exported by the comparison code of this address;
S6, then to arrange on A comparison code display panel and B comparison code display panel
Comparison code display driver, this driver accepts the comparison code that comparison code memory is sent here, shows after process on comparison code display;
S7, be then placed in monitored scene can take in the position of camera lens by camera being shot by arbitrary in A comparison code display panel, B comparison code display panel; Another is placed in Control Room.
According to present clock described in step S5, decoder chooses a storage address to be carried out a refresh operation every 2 seconds ~ 30 seconds.
The A comparison code display panel being placed in monitored scene described in step S7 is more than one.
Driver described in step S6 accepts the comparison code that comparison code memory is sent here, and show on comparison code display after process, display format comprises at least one of numeral, character, figure.
Manufacture and design a kind of device that the monitor video true and false is transmitted at scene of differentiating according to said method, described device comprises:
A comparison code display panel and B comparison code display panel, use in groups; Two comparison code display panels all arrange comparison code display, and shown comparison code form is identical;
