[0101] Specifically, a bounding box is an algorithm for finding the optimal bounding space for a discrete point set. The basic idea is to use a geometric body with a slightly larger volume and simpler characteristics (called a bounding box) to approximately replace complex geometric objects. Common bounding box algorithms include AABB bounding box, bounding sphere, directional bounding box OBB and fixed directional convex hull FDH. The collision detection problem has a wide range of applications in virtual reality, computer-aided design and manufacturing, games, robotics and other fields, and has even become a key technology.

[0124] The abnormal behavior detection module is used to monitor the disappearance, gathering and overtime abnormal behaviors of personnel in real time;

[0125] The electronic fence area management module is used to set the electronic fence area on the front end of the web page and issue an alarm to remind people entering and leaving the area;

[0126] The SOS alarm module is used to receive emergency information sent by factory personnel;

[0127] Specifically, the positioning card is equipped with an SOS alarm button. In an emergency, factory personnel can use the SOS button to send an emergency signal for help.

When bidding, it is necessary to provide a report format for abnormal alarm information, which should reflect the basic information supporting fault handling.

[0134] The system security management module 7 is used to assign different management rights to different managers and manage the smart lighting fixtures, personnel positioning devices, and smart consoles.

[0135] In one embodiment, allocating different management rights to different managers includes the following steps:

[0136] Administrators set different permission operations, and others only have viewing permissions but no modification permissions;

[0137] Collaborators obtain corresponding permissions, and in the process of management, multiple people collaborate to manage and edit content;

[0138] Based on OT algorithms, managed content is acquired in real time and collaboration between collaborators is shared.

[0139] In one embodiment, the OT algorithm comprises the following steps:

[0140] Describe the modification of document data;

[0141] The modification of document content is carried out through two-way communication between the WebSocket protocol and the server;

[0142] Record and synchronize changes to document content.

[0143] In one embodiment, the collaborator obtains corresponding permissions, and in the process of management, multi-person collaborative management of editing content includes the following steps:

[0144] If a new collaborator without permission wants to join the collaboration, he or she needs sharing authorization from the administrator;

[0145] Once a new collaborator is added as a collaborator, they can enter the management workbench page;

[0146] If the user is not a collaborator or project creator, the user has no permissions to the project. If the user is a project creator, the user can view the list of shared members and set the collaboration permissions for shared members.

[0147] The shared members are administrators, and there may be multiple or none of them.

[0148] Specifically, Figure 2 As shown, an embodiment of the OT algorithm is as follows. The basic idea of ​​maintaining content consistency in the OT algorithm is that two collaborators open the same management document in the system, and the initial content of the document is "xyz".

[0149] Collaborator 1 and collaborator 2 operate at the same time. Collaborator 1's operation is O1=Insert(0,a), which means inserting string a at position 0; collaborator 2's operation is O2=Delete(2,1), which means deleting elements starting from the second position, and the deletion length is 1.

[0150] The string in collaborator 1's browser first becomes "axyz". After the O2 operation reaches the collaborator 1's browser, it is transformed with O1 as O2′=Transform(O2, O1)=Delete(3, 1). Although O2′ also performs a deletion operation, because O1 has already inserted the a string, the deletion position is +1, and O2′ becomes an element with a deletion starting position of 3. The deletion length is 1. The O2′ operation is performed on "axyz", and the local string of collaborator 2 becomes "axy".

[0151] The string in collaborator 2's browser first becomes "xy". After the O1 operation reaches the collaborator 2's browser, it is transformed with O2 as O1′=Transform(O1, O2)=Insert(0, "a"). Because the element deleted by O2 starts from the second position, it has no effect on the added element of O1′, so O1′=O1. The O1′ operation is performed on "xy", and the local string of collaborator 2 becomes "axy".
