In this embodiment, the camera adopted by the monitoring module needs to have the basic functions of video shooting/transmission, still image capturing and the like, and supports night infrared shooting, waterproof, sun-proof, dustproof and dampproof, and USB data transmission.
The power supply module comprises a solar panel and an energy storage battery pack, wherein the solar panel converts solar energy into electric energy and the energy storage battery pack stores the electric energy, and the energy storage battery pack provides electric energy for other modules.
The 4Gcat module is in communication connection with the server module by adopting an MQTT and HTTP protocol.

The active alarming working mechanism of the alarming module is that according to the distance between the object position positioned by the UWB module and the boundary of the dangerous area, when the distance between the movable object and the boundary of the dangerous area is less than or equal to 3m, the alarming module actively alarms to the server module.
The voice warning working mechanism of the warning module is that the movable object enters the scanning range of the UWB module, the distance between the movable object and the boundary of the dangerous area is less than or equal to 10m, and the warning module sends out voice warning.
The alarm module is provided with an emergency button, and personnel can actively communicate with background staff through the emergency button in a voice way.
The scanning range of the UWB module is 360-degree scanning, and the radius of the UWB scanning module is 50-100 m.
The size of the UWB scanning radius is selected according to the requirements of users to set UWB modules with different scanning radii.

Referring to fig. 2, in this embodiment, when the moving object is relatively close to the boundary of the dangerous area, three UWB modules are used to locate the moving object, where the three UWB modules include two inner UWB modules along the boundary of the dangerous area and one outer UWB module located near the boundary of the dangerous area, when the moving object enters the scanning range of the three UWB modules, it is indicated that the moving object is close to the dangerous area, the distances between the three UWB modules and the moving object are respectively R1, R2, R3, and the coordinates of the three UWB modules are respectively (X1, Y1), (X2, Y2), (X3, Y3), and the boundary position of the dangerous area can be located by the coordinates of the two inner UWB modules, and then the distance between the moving object and the boundary of the dangerous area is calculated by the above known data through a trigonometric function formula, where the calculation formula is as follows:
(X1-X0) 2 +(Y1-Y0) 2 ＝R1 2
(X2-X0) 2 +(Y2-Y0) 2 ＝R2 2
(X3-X0) 2 +(Y3-Y0) 2 ＝R3 2
wherein, (X0, Y0) is the current coordinates of the active object.
The distance h between the movable object and the boundary of the dangerous area can be calculated through the coordinates of the movable object.
The boundary of the dangerous area is divided into a plurality of point coordinates in advance, the distances between the current coordinates of the movable object and the boundary point coordinates of the plurality of dangerous areas are calculated by calculating the obtained current coordinates of the movable object and the distances between the (X0, Y0) and the plurality of boundary point coordinates respectively, and the smallest value, namely the distance between the movable object and the boundary of the dangerous area, is selected.
The graphic representation L represents the boundary of the unsafe zone, L1, L2, L3 represent a plurality of boundary point coordinates,
in another embodiment, the boundary is located by using the connecting line between the two inner UWB modules, and the connecting line is used as the Y axis of the coordinate axis, so that the absolute value of the abscissa of the current coordinate of the movable object, namely the distance h between the movable object and the boundary of the dangerous area, is simpler and has higher calculation speed although the algorithm has slightly insufficient accuracy.
