Embodiment Construction
[0016] In order to further explain the technical means adopted by the present invention and the effects obtained, the technical solutions of the wireless video monitoring system frequency control method and device proposed by the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments .
[0017] see figure 1 , is a schematic flowchart of the frequency control method of the wireless video surveillance system of the present invention. The wireless video surveillance system frequency control method of the present invention comprises the following steps:
[0018] S101 acquires the working frequency of the receiving unit of the backend command center;
[0019] The sending unit of the front-end communication equipment adopts different frequencies, that is, the sending units of each front-end communication equipment of the wireless video surveillance system use different frequencies, but must correspon...

The invention discloses a frequency control method of a wireless video monitoring system, which comprises the steps of: obtaining a working frequency of a rear end commanding center receiving unit; sending a working frequency correction instruction to a front end communication device sending unit according to the obtained working frequency of the rear end commanding center receiving unit; and regulating the working frequency of the front end communication device sending unit according to the sent working frequency correction instruction. In addition, the invention discloses a frequency control device of the wireless video monitoring system, which comprises a working frequency obtaining module, a rear end sending module and a front end control module. According to the frequency control method and device of the wireless video monitoring system, provided by the invention, through controlling the working frequency of a front end communication device, the condition that a rear end commanding center must adopt same frequency points as the front end communication device in a one-to-one correspondence manner is avoided, so that the quantity of the rear end commanding center receiving units for receiving video monitoring information and occupied frequency resources are greatly reduced.
Description
technical field [0001] The invention relates to the technical field of wireless video monitoring, in particular to a frequency control method and device for a wireless video monitoring system. Background technique [0002] At present, in the wireless video surveillance system, video transmission occupies a large bandwidth, the front-end video sending unit uses a fixed frequency point, and the background command center receiving unit must use the same frequency point as the front-end communication equipment sending unit. If the wireless video surveillance system has multiple front-end sending units, the back-end must have the same number of corresponding receiving units, and must use the same frequency in one-to-one correspondence. When the scale of the wireless video surveillance system is large, the system will occupy a lot of frequency resources. For example, when the system contains 10 video surveillance front-end units, it needs to occupy 10 frequency points, and the bac...
