A second embodiment of the invention relates to a method of work management. The second embodiment is a further improvement of the first embodiment, and the specific improvements are as follows: in a second embodiment of the present invention, the task information further includes work area information of the borrower; when the task information includes material information of a borrowed object, before identifying that the state of the borrowed object is a borrowed state, the method further includes: defining N working areas, wherein N is a constant greater than 1; before the determining whether the material information of the borrowing object exists in the task information, the method further includes: judging whether the borrower has the authority to enter the current working area or not according to the working area information; and if the borrower has the authority to enter the current working area, judging whether the task information contains the material information of the borrowed object. When the material information of the borrowed object exists in the task information, before the state of the borrowed object is marked as the borrowing state, whether the borrower has the authority to enter the current working area is judged, it is ensured that not all people can enter any area in the greenhouse, the worker can only enter the working area corresponding to the authority of the worker, and the material in the working area is borrowed, so that the borrowing of the material and the management of the worker are more reasonable and ordered.

As shown in fig. 2, the work management method in this embodiment specifically includes:

s201: n working areas are defined.

Specifically, in step S201, N is a constant greater than 1, and a working area can be defined by an infrared correlation device, which is called an "Active infrared intrusion detector" (Active infrared detectors) and has a basic structure including a transmitting end, a receiving end, a beam intensity indicator, an optical lens, and the like. The detection principle is that infrared rays emitted by an infrared light emitting diode are focused by an optical lens, so that the rays are transmitted to a long distance, and finally the rays are received by a photosensitive transistor at a receiving end. When an object blocks the infrared ray emitted by the emitting end, the receiving end can not receive the infrared ray, so that an alarm can be given. Infrared is an invisible light and is diffused and, after being projected, forms a cone beam in the initial path, the ideal intensity of which decays inversely square with the distance of emission as the distance of emission increases. When an object crosses its detection zone, the infrared beam is intercepted, causing an alarm.

It is worth mentioning that the greenhouse can cancel framing in the system, close infrared sensing, or expand, reduce the working area, merge the working area, the system can transmit the selected instruction to the relevant maintenance personnel according to the final selection, adjust the infrared sensing range of the hardware, and the front-end display automatically updates the mapping area according to the selection.

S202: and acquiring the identity information of the borrower.

S203: and acquiring the task information of the borrower according to the identity information.

Specifically, in step S203, the task information at least includes the task execution time length of the borrower and the work area information of the borrower.

S204: and judging whether the material information of the borrowed object exists in the task information or not when judging that the borrower has the authority to enter the current working area according to the working area information.

Specifically, in step S204, each worker has corresponding permissions, for example, the workers in the planting area can only borrow the materials in the planting area but cannot borrow the materials in the transportation area, so that anyone can not borrow all the materials in the greenhouse, and the workers can only borrow the materials corresponding to the permissions, thereby borrowing the materials more reasonably and orderly.

S205: when the material information of the borrowed object exists in the task information, sensing first characteristic information used for representing the borrowed object in real time, and detecting whether the borrowing time length exceeds the task execution time length in real time.

Specifically, in step S205, the borrowed material generally refers to a production tool in an agricultural system, and the production tool is also called a labor tool, and is an object used by people to directly process a labor object in a production process. It is used between the laborer and the laborer to conduct the laborer. Is the basic and main part of labor data, and is the mechanical labor data. From the original stone axe and the bow and arrow to the modern various machines, tools, technical equipment and the like, the machine also plays a role of conducting labor, and belongs to production tools.

S206: and when the borrowing time exceeds the task execution time, sending alarm information to remind the borrower to return the borrowed materials.

Steps S202 and S206 in this embodiment are similar to steps S101 and S104 in the first embodiment, and are not described here again to avoid redundancy.

It is worth mentioning that, in this embodiment, after the borrower has the right to enter the current work area and determines that the material information exists in the task information, the method further includes: judging whether the borrower has the authority to borrow the materials in the current working area; and if the materials in the current working area are allowed to be borrowed, then performing real-time induction to represent the first characteristic information of the borrowed object being borrowed, and detecting whether the borrowing time length exceeds the task execution time length in real time. By the method, the borrower can only borrow the materials in the specific working area, so that the materials are managed more orderly.
