Problems solved by technology

[0006] At present, the design of the digital TV playback mode is relatively rough. The playback strategy for each TV station is roughly the same, and the playback strategy for each TV program is roughly the same. The customization of the playback mode, not to mention the specificity and flexibility of the programming strategy of future TV programs and the programming strategy of watching TV programs, so that it is easy to cause discomfort to TV viewers when watching back, for example, due to insufficient bandwidth. Can't enter the program review status, and can't provide reference data for TV program provider's programming

Embodiment Construction

[0019] The implementation of the Internet of Things greenhouse agricultural growth monitoring system of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Compared with analog TV, digital TV has the following advantages: The wave ratio is independent of the number of consecutive processing. After digitization, the TV signal is represented by two binary levels of several bits. Therefore, after the clutter is introduced in the continuous processing process or in the transmission process, as long as the clutter amplitude does not exceed a certain rated level, it can be passed through the digital signal. Even if a certain clutter level exceeds the rated value and causes bit errors, they can be corrected by using error correction encoding and decoding technology. Therefore, in the process of digital signal transmission, the signal-to-clutter ratio will not be reduced. In the processing and transmission of analog signals, n...

Abstract

The invention relates to an agricultural growth monitoring system for greenhouses of the Internet of Things, which includes growth monitoring equipment, program information sending equipment, DSP processing chips and rating statistics equipment, and the DSP processing chip is based on the program name of the currently playing TV program sent by the program information sending equipment Count the number of times of the program name of the currently broadcast TV program within the preset time, update the broadcast frequency of the currently broadcast TV program in real time based on the above times, and also adjust the playback of the currently broadcast TV program in real time based on the broadcast frequency of the currently broadcast TV program in the future previous ad duration.

Description

technical field [0001] The invention relates to the field of monitoring, in particular to a method for monitoring agricultural growth in an Internet of Things greenhouse. Background technique [0002] The amplitude separation circuit uses the characteristic that the synchronous signal has the highest amplitude in the whole TV signal to take out the composite synchronous signal. The integration circuit uses the characteristic that the width of the field synchronous signal is much smaller than the width of the horizontal synchronous signal to separate the field synchronous signal from the composite synchronous signal. Come out to control the field scanning circuit to realize the synchronization of TV field scanning. [0003] The separation method of the integral circuit is also called width separation. The function of the AFC circuit is to automatically realize line synchronization. The principle is to take the horizontal synchronous signal out of the composite synchronous si...
