Problems solved by technology
The above two patent application technologies are mainly used in the situation where the analog-to-digital conversion of the image signal is first realized and then transmitted to the outside. It cannot be applied to transmission occasions such as digital cameras where the shooting results have been saved as digital image files, and the converted results are separated. Using bluetooth and GPRS or CDMA wireless network separate transmission mode
However, the wireless transmission distance of the existing Bluetooth technology is too short, and the re-establishment of the Bluetooth transmission channel requires manual intervention, which is difficult to meet the requirements of self-sustained transmission of image data; at the same time, the wireless transmission based on GPRS or CDMA technology adopts a separate upload method, and the overall cost of hardware equipment higher

Embodiment
[0019] Such as figure 1 Shown, the working schematic diagram of this embodiment. This embodiment is mainly used in the field, where several melon image sensors are distributed in the field. Each image download module of the present invention is connected to the melon image sensor through the serial communication interface 1 through the data line, and the image download module downloads the melon image sensor from the melon image sensor. The image file is temporarily cached in the on-site high-speed static RAM, and then the melon image file is uploaded to the embedded central memory module for centralized storage through the serial communication interface 2 through the ZigBee wireless transmission channel according to the agreed format, and the embedded central memory module is then passed through the RJ45 The Ethernet interface sends the melon image to the 3G wireless transmission module, and the melon image is uploaded to the image processing server through the wireless remot...

The invention discloses a static melon image wireless transmission network device utilizing a Zigbee wireless transmission technology in the technical field of agricultural cultivation. The device consists of an image downloading module, an embedded central storage module and a 3rd-generation (3G) wireless transmission module, wherein the image downloading module downloads images from image sensors, and is connected with the embedded central storage module by a transmission channel; the embedded central storage module receives the images uploaded by the image downloading module, temporarily stores the received images, and is connected with the 3G wireless transmission module by a network cable; and the 3G wireless transmission module uploads the images to a remote image processing server. The device can periodically receive the images from a plurality of static melon image sensors in fields with low cost, high stability, low energy consumption and high security, and remotely wirelessly transmit the received images to the image processing server, is applied to experimental researches on melons, and remotely, highly efficiently and stably acquire image information acquired by the plurality of static melon image sensors from the image processing server.
Description
technical field [0001] The invention relates to a network device in the technical field of agricultural cultivation, in particular to a wireless transmission network device for still images of melons using Zigbee wireless transmission technology. Background technique [0002] The formation of muskmelon organ morphology is the expression process of internal physiological processes. It is affected by the synergy of nutrients, signals, regulatory factors and other factors. The morphological development information of muskmelon is recorded in the form of images, and then the growth of muskmelon is realized through computer image processing. The real-time non-destructive monitoring of the situation is very important for analyzing the coupling relationship between the characteristic parameters of melon and the internal development mechanism. However, in order to quickly and timely apply the acquired image data of melons to scientific research, many intermediate processes are still...
