The connection includes: at least more than one hard disk video recorder/digital matrix which can be a first hard disk video recorder/digital matrix, a second hard disk video recorder/digital matrix, or a N-th hard disk video recorder/digital matrix, at least more than one network matrix which can be a first network matrix, a second network matrix or an M-th network matrix; and a control keyboard. The control keyboard is respectively connected with a RS232-485 module in the first hard disk video recorder/digital matrix, a RS232-485 module in the second hard disk video recorder/digital matrix, a RS232-485 module in the N-th hard disk video recorder/digital matrix, a RS232-485 module in the first network matrix, an RS232-485 module in the second network matrix and an RS232-485 module in the M-th network matrix through a communication wire. Since a plurality of hard disk video recorders/digital matrixes and network matrixes are controlled by one control keyboard, the work efficiency is improved and the unified control is coordinated.

Description

The video monitoring control connection and the method thereof of network matrix and DVR/character matrix

Technical field

The present invention relates to the video monitoring of a kind of network matrix and DVR/character matrix, relate in particular to the control connection and the method thereof of this video monitoring.

Background technology

DVR (DVR) be meant receiving video signals and can realize supervising, the equipment of function such as video recording;

Character matrix (DMS) is meant has increased the function that video is outputed to corresponding monitor on the basis of DVR;

Network matrix (DNS) is meant that the vision signal with DVR or DMS is that some transmission medium is decoded to network terminal and outputed to video wall with the network.

Because of relating to multiple devices, general traditional method is controlled system needs many control appliances (supervisory keyboard), just man-to-man control in the video monitoring system that with network matrix and DVR/character matrix is the center.But so much supervisory keyboard will produce inefficient operation, waste of manpower cost under actual operating position, and unified controlled factor such as bad.

How will be science and technology personnel technical issues that need to address by control appliance control multiple devices.

Summary of the invention

The technical issues that need to address of the present invention have provided the video monitoring control connection of a kind of network matrix and DVR/character matrix, are intended to solve the above problems;

The present invention also provides a kind of control method that adopts above-mentioned connection.

In order to solve the problems of the technologies described above, control connection of the present invention is achieved through the following technical solutions:

The present invention includes: at least more than one DVR/character matrix: can be first DVR/character matrix, second DVR/character matrix, N DVR/character matrix, at least more than one network matrix: can be first network matrix, second network matrix, M network matrix; Also comprise a supervisory keyboard; Described supervisory keyboard links to each other respectively by the RS232-485 module in connection and the first DVR/character matrix, the RS232-485 module in second DVR/character matrix, the RS232-485 module in N DVR/character matrix, the RS232-485 module in first network matrix, the RS232-485 module in second network matrix, the RS232-485 module in the M network matrix.

Control method of the present invention realizes by following steps:

Operation keyboard is arranged to and each DVR/character matrix or unique corresponding request code of network matrix and required request command data;

Send to this request code and request command data in the RS232-485 module of DVR or network matrix by 485 buses;

If in request code and the RS232-485 module identification code can correspondence on, then carry out the desired action of request command, if can then not do any processing on the correspondence.

Compared with prior art, the invention has the beneficial effects as follows: owing to be that a supervisory keyboard can be controlled a plurality of DVR/character matrixs and network matrix, improved operating efficiency, coordinated unified control.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

As seen from Figure 1: the present invention includes: at least more than one DVR/character matrix: can be first DVR/character matrix, second DVR/character matrix, N DVR/character matrix, at least more than one network matrix: can be first network matrix, second network matrix, M network matrix; Also comprise a supervisory keyboard; Described supervisory keyboard links to each other respectively by the RS232-485 module in connection and the first DVR/character matrix, the RS232-485 module in second DVR/character matrix, the RS232-485 module in N DVR/character matrix, the RS232-485 module in first network matrix, the RS232-485 module in second network matrix, the RS232-485 module in the M network matrix.

Control method of the present invention realizes by following steps:

Operation keyboard is arranged to and each DVR/character matrix or unique corresponding request code of network matrix and required request command data;

Send to this request code and request command data in the RS232-485 module of DVR/character matrix or network matrix by 485 buses;

If in request code and the RS232-485 module identification code can correspondence on, then carry out the desired action of request command, if can then not do any processing on the correspondence.

As seen from Figure 2: Camera is an optical camera among the figure, and Pan is a The Cloud Terrace: can control the equipment that video camera rotates up and down; Quick Ball is a quick: can control video camera up and down and 360 the degree high speed rotating equipment.

Operating personnel require to inform man-machine session module (operation keyboard) with institute, the human-computer dialogue module sends to data on the 232-485 module of each equipment (DVR/DMS/DNS) by 485 buses, 232 signals that become computer to discern 485 conversion of signals, because of each equipment (DVR/DMS/DNS) all has a unique identification code (address code), so at first read identification code (address code) after every equipment (DVR/DMS/DNS) receives request command, if request code and identification code (address code) can correspondence on, then carry out the desired action of request command, if can then not do any processing on the correspondence.
