The network transmission module is responsible for connecting a remote server so as to transmit the acquired data such as meteorological information, pest quantity information, image information and the like to the server end for a user to check.
The data acquisition part 2 has a low power consumption mode, for example, when the acquired air temperature is too low, the low power consumption mode is entered, the power consumption of the system is reduced, and the power loss is reduced.
Fig. 5 is a schematic structural diagram of an upper computer software system provided in the present invention, and as shown in fig. 5, the upper computer software system is mainly used for viewing, automatically identifying, and manually identifying and downloading data collected by the system.
The user can enter the software system by means of a client side capable of being connected with the Internet, such as a computer, a mobile terminal and the like, and can enter a real-time monitoring 52 functional interface after login is realized through a login 51 interface, and all devices in the whole pest real-time detection counting system are displayed on the interface. Other functional interfaces can be accessed respectively through functional frame selection, and the interfaces comprise a pest data statistics 53 interface, a pest image identification 54 interface, a historical data viewing 55 interface and the like.
The upper computer software system can be loaded in the image recognition part 3, and can automatically detect the target pests in the picture and identify the target pests after receiving the picture. The automatic identification result can be viewed on the pest image identification 54 interface, and the user can manually modify the result to correct the identification result.
For example: the user can check the target images shot by the image acquisition device 13 through the pest image identification 54 interface, and can individually identify each image to judge whether target pests fall into the acquired target images and mark and identify the target pests in the images, so as to correct the number of the pests detected by the photoelectric counting device.
According to the real-time pest detecting and counting system, data and images detected by the whole system are displayed through the upper computer software system, so that manual identification work of a user can be carried out, the false triggering condition generated in the photoelectric counting device can be corrected, meanwhile, the counting phenomenon caused by non-target pests falling into the trapper can be eliminated, and the counting value is more accurate. And the data of the upper computer software system is checked and the image is identified, so that a visual monitoring result is provided for the working personnel, and the image is combined with the data, so that the specific deviation caused by single data is avoided.
Through the above description of the embodiments, those skilled in the art will clearly understand that each embodiment can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware. With this understanding in mind, the above-described technical solutions may be embodied in the form of a software product, which can be stored in a computer-readable storage medium such as ROM/RAM, magnetic disk, optical disk, etc., and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the methods described in the embodiments or some parts of the embodiments.
