Problems solved by technology

[0006] In some large buildings or commercial buildings, there are often many functional areas and complex layouts, and sometimes vertical traffic and other issues are involved, so unfamiliar users are easy to get lost in the building, or need to constantly ask the staff, which takes a lot of time To be able to find the target room; For museums, exhibition halls and other buildings, users often need to visit with a certain carefully designed path to achieve the best visiting effect, and users often lack corresponding path guidance; Important people often have the need to be found. For example, company employees want to know the current location of the general manager so that they can find him to report to work, so they hope to be able to locate him conveniently and get path guidance
[0007] In the event of dangerous emergencies such as fires and violent attacks in buildings, it is necessary to evacuate personnel, but the existing technology can only provide fixed safety exit signs, and cannot be based on the actual location of fire and other dangerous situations and the actual distribution of personnel. Provide flexible evacuation guidelines

Embodiment 1

[0114] The optimization calculation method provided by the present invention is applied to indoor navigation.

[0115] Combine figure 2 , There are several space areas in the building 100, the space areas are adjacent to each other and independent of each other; each space area has data receiving, processing, and sending function node units, with A, B, C, D, E , F, G, H, I represent the node units, and the solid black lines between each node unit represent the topological connection between the rooms. Because these spaces are directly connected physically, people can directly move from one area To reach another area, for example, people can directly reach room B and room D from room A, but cannot directly reach room E from room A, so there is a connection between each node unit, and each node unit forms a distributed Computing network. T marked on the connection between each room AB , T BC The waiting mark represents the estimated time t required for a person to get from one ...

Embodiment 2

[0138] Table 2

[0139]

[0140] As the starting point of the calculation, A sends 0 to all its neighbors. B and D accumulate the time to reach the source node A based on the data sent by the source node A, and send it to all neighbor nodes (B sends to A, C and E, and D are sent to A, G and E, but B and D are not recorded in the table and sent to node A), the nodes that receive the data repeat this process, and accumulate them on the basis of the data sent by the source node The time to reach the corresponding source node is sent to all neighboring nodes after data selection. The node unit will perform this processing every time it receives data. Taking node E as an example, suppose it first receives B and sends it to it. Data and calculate 0+t AB +t BE This result, E sends the result to all neighboring nodes; then E receives the data sent to it by D, and calculates 0+t AD +t DE This result, at this time, E will judge whether it is less than the previous result 0+t AB +t B...

Embodiment 3

[0146] The optimized calculation method provided by the present invention is applied to fire evacuation.

[0147] When a sudden emergency such as fire, explosion, robbery occurs in the building, the crowd needs to be evacuated immediately. Traditional evacuation systems provide people with fixed evacuation guidance, indicating emergency exits and safety signs showing the direction of stairs. This kind of fixed evacuation guidance cannot effectively adapt to emergencies, because accidents may occur anywhere in the building, and the distribution of people in each room at the time of the accident cannot be predetermined.

[0148] Based on the building information system, real-time information on the distribution of people in the building can be obtained, as well as the location, intensity and development trend of disasters. Based on this real-time information, the safest and fastest escape route can be dynamically planned, and the display in each room and traffic artery can guide the...

Abstract

The invention discloses an optimal computation method of a shortest path based on centerless network. The method comprises the following steps: based on the centerless building control concept, firstlybidiing a building into multiple adjacent and independent space areas, then placing a node unit in each space area, wherein the node unit is a computer having data receiving and sending and processing functions, all node units are connected with one another to form a centerless computation network, the node units can perform data interaction to computer the shortest path between any two nodes, and the interaction information comprises a pre-estimated time from one node to the adjacent node. By adoption of the method, navigation and crowd evacuation in the case of dangers in the building can be realized, and real-time and flexible path guidance information is provided. By adoption of the computation method, a plurality of path optimization results can be obtained, and in addition, the optimal computation method can also be applied to navigation and evacuation of urban blocks and roads.

Description

Technical field [0001] The invention relates to the field of building control, in particular to a method, system and device for path optimization. Background technique [0002] CN103809541A discloses a control system and method for a building or a group of buildings. This document discloses a control method for buildings. The document proposes a control method that divides the building into several space units and builds node units in each space unit to form a central control network. This invention creatively puts forward the concept of a centerless, distributed building control network, which is a subversion of the traditional centralized building automation system architecture. Under this concept, there are still many control algorithms that need to be developed to fill this technology. Gaps in the field. [0003] For example, CN105045225A discloses a water pump system, a water pump controller and a control method based on a centerless network, and CN105091213A discloses a chi...
