Embodiment Construction
[0015] The invention provides a digital TV signal quality detection system, such as figure 1 As shown, including the signal detection box, server and client, each part will be described in detail below.
[0016] The number of signal detection boxes is one or more, and they are remotely connected to the server system. The remote connection is realized through a monitoring module and a data sending and receiving module. The communication method includes a 3G communication module, a 4G communication module and a 5G communication module. When in use, the signal detection box is set on the key path node of the digital TV channel signal transmission, for example, it is set in the computer room where the digital TV channel signal is received, and is used to collect the digital TV channel spectrum signal in real time, and analyze the digital TV channel spectrum signal Perform demodulation, and analyze signal data such as signal strength, modulation error ratio, signal-to-noise ratio, ...

The invention relates to the field of digital television signal quality monitoring, and discloses a digital television signal quality detection system which solves a problem that technicians need to visit and check in the traditional digital television signal quality detection scheme, thereby being convenient for the technicians to dynamically check the digital television signal quality of a certain area or a certain building in real time. The digital television signal quality detection system comprises a signal detection box, a server and a client, and is characterized in that the signal detection box is set on path node for digital television channel signal transmission and used for collecting digital television channel spectrum signals in real time, demodulating the digital television channel spectrum signals, parsing out signal data according to a demodulation result and transmitting the parsed signal data to the server for storage; and a user can perform management control on thesignal detection box in real time through the client and check the digital television signal quality state detected by the signal detection box. The digital television signal quality detection systemis applicable to digital television signal operation and maintenance.
Description
technical field [0001] The invention relates to the field of digital television signal quality monitoring, in particular to a digital television signal quality detection system. Background technique [0002] At present, with the deployment of more and more set-top boxes in the field of broadcasting and television, users have higher and higher requirements for network quality. In many cases, the reason for the poor TV signal of set-top boxes reported by users is not because of the poor signal of the backbone network, but partly because of users. Maybe the signal is not connected well and other reasons. However, there is currently no effective method to remotely and dynamically check the signal situation in a certain area of the user in real time. Every time a technician needs to visit the site to check, the operation and maintenance cost is very high. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a digital T...
