The invention relates to the technical field of silkworm breeding auxiliary devices, and specifically relates to an intelligent comprehensive monitoring system for silkworms. The intelligent comprehensive monitoring system for silkworms comprises an image acquisition module, an image recognition module, a temperature and humidity acquisition module, an illumination detection module, an intelligentcontrol module, a PLC (Programmable Logic Controller), a communication module and a remote mobile terminal which are mutually electrically connected, wherein the image acquisition module is used foracquiring a color image of a silkworm rearing bed, the image recognition module is used for recognizing the quantity of the silkworms and the quantity of residual mulberry leaves, the temperature andhumidity acquisition module acquires the temperature and the humidity, the illumination detection module detects the illumination intensity of the silkworm rearing bed, the PLC is connected with the temperature and humidity acquisition module and the illumination detection module, the intelligent control module is used for judging whether it is needed to supply the mulberry leaves or not and the supply quantity of the mulberry leaves, and the communication module is used for transferring alarm information to the remote mobile terminal. The intelligent comprehensive monitoring system for silkworms achieves unattended operations through monitoring the quantity of silkworms of the silkworm rearing bed, the quantity of the residual mulberry leaves, the temperature, the humidity and the illumination, presetting alarm condition and notifying the alarm information to a manager, thereby relieving the workload of silkgrowers.
