Description
Technical field
The present invention relates to technical field of fire safety, is to be related to a kind of fire based on laser total station to build specifically
Build detection early warning system and its detection method for early warning.
Background technology
Fire be usually people because with fire it is improper caused by contingency, once fire incident occurs, people go as possible
Its caused life and property loss is reduced, therefore fire-fighting and rescue also produces.When fire occurs for building, cigarette caused by the scene of a fire
The burning of gas, high temperature and fire to building element can all destroy to building structure, makes building that certain deformation occur, works as change
Shape reaches to a certain degree, and building will collapse, and this is by the life security of serious threat fire-fighting and rescue personnel into the scene of a fire.Cause
This, the malformation that how detecting building in advance in a fire will occur becomes most important, and this is the equal of to disappear
Anti- rescue personnel gives warning in advance, and ensures the life security of these personnel.
Inventor proposed in patent application 2017105197077 and 2017207776370 by generating laser come
Carry out building deformation measurement method, used apparatus structure due to having used generating laser accessory costly,
So that the purchase cost of whole device is higher, it is not easy to promote, it is relatively low in widespread adoption, it is therefore desirable to which that one kind can either be effective
Measure the measurement apparatus that building deformation situation, holistic cost are relatively low in fire.

Built into fire and carry out rescue, while fire-fighting logistics lays the present invention in fire building external and carries out fire building deformation
Early warning is detected, logistics guarantee is provided for the life security of fire fighter.Four total powerstations are erected at before and after fire building successively
The positive orientation in left and right four (installation error for allowing low-angle), total powerstation keep rational detecting distance with fire building, kept away
The aobvious barrier of enlightenment, ensure that the visual field is more spacious between total powerstation and fire building, adjusting each total powerstation respectively makes its alignment fire
Calamity building measures, and is each total powerstation connecting communication extension set, as shown in figure 5, now can be no longer at each total powerstation
Arrange monitoring personnel on duty, or only one duty personnel of unified arrangement comes and goes patrol, can greatly reduce cost of human resources.Data are supervised
Control platform is placed at or near fire-fighting command point, and the communication extension that the host computer communication being connected through is connected with total powerstation is carried out
Monitoring Data gathers and transmission, can be by the total powerstation in positive orientation and its corresponding communication point in another prioritization scheme
Machine is arranged on data monitoring position of platform, and the communication extension is used directly as host computer communication, to receive and transmit other
The data of communication extension collection, to save device resource；Calculating is uniformly collected by data monitoring platform again, now only needed in number
It can check that fire builds Monitoring Data situation according to the professional of monitor supervision platform position arrangement one is on duty, when total powerstation detects data
Mathematic interpolation result exceed threshold value set in advance, send alarm in the alarm module of data monitoring platform, show that fire is built
The danger that certain oriented side is collapsed is built, fire-fighting command point is reported by the duty personnel, notifies the fire fighter of rescue to enter in time
Row is withdrawn, and is ensured the safety of human life.
On the other hand, fire-fighting command personnel can also be in the deformation feelings of the current fire building of data monitoring platform real time inspection
Condition, enter row major rescue to the part that will collapse of prediction according to data feedback information commander fire fighter, then remove in time
From striving for rescuing more life and property as far as possible.
Above-described embodiment is only the preferred embodiments of the present invention, not limiting the scope of the invention, as long as using
The design principle of the present invention, and the change for carrying out non-creativeness work on this basis and making, all should belong to the present invention's
