And the addition of human project activity also aggravate geological calamity risk.

Basically qualitative calamity type

At present prevention and cure of calamity of our country ground still is put in investigation precision canal of danger of zephyr of the inadequacy of application of method of insufficient, advanced technique, hidden trouble identifying, early-warning that monitor accuses ability to wait for weak point not by force. To ensure safety of people life property, the monitoring early-warning that raises various government to break out incident to geological calamity and canal accuse strength, earnestly needs to carry out calamity to monitor early-warning informatization project, rise monitor, identify and early-warning ability.

National height takes geological calamity prevention and cure seriously

In recent years, the loss that geological calamity causes presents the trend that gives accentuation, go against our country economy to build development not only, also caused great menace to the life of people and belongings safety. The country raised taller requirement to job of geological calamity prevention and cure. The 20 big reports of the party put forward clearly to want " raise take precautions against natural calamities to decrease calamity provides disaster relief and great break out communal incident to deal with safeguard ability " . Rich ministry was released in December 2022 " countrywide geological calamity prevents and cure " 945 " program " put forward clearly to want to be perfected soundly defend the system of comprehensive prophylaxis and treatment that accuses to give priority to a line with geological calamity risk, promote the information of science and technology that geological calamity prevents and cure capability significantly, make full use of the method such as information of geography of homebred satellite, unmanned aircraft, mapping and ground investigation, trends of hidden trouble of promotion geology calamity identifies technical level; to apply technology of confluence of data of wireless group net and technology of content couplet net, GNSS technology, much parameter integratedly to wait for new-style technology measure, general of research and development is comfortable model intelligence changes real time to monitor early-warning equipment to wait.

With " core " monitor effective prophylaxis and treatment

Geological calamity has calamity catenary effect, the mechanism that cause disaster is complex wait for a characteristic, the early-warning that monitor is the important and significant step that answers calamity actively. The distributinging change rule that knows geological calamity to go up in time and space in real time, it is the key that scientific take precautions against natural calamities decreases calamity. Deformation monitors the stress that still is geological calamity prevention and cure, and the core that deformation monitors depends on monitoring tiny displacement, the monitoring equipment of high accuracy and technology are the key that monitors tiny displacement.

The specific requirement that to satisfy a state right calamity prevention and cure works, domestic mainstream north fights high accuracy to locate manufacturer Hua Dabei fights chip to issue high accuracy to monitor service firm rice to spend with the banner measure accuse, around " chip class " the high accuracy technology that monitor began science and technology to tackle key problem innovate with the technology, target compose builds the automation of round-the-clock geological calamity that is based on north to fight technology of chip of high accuracy fixed position to monitor a system, shirt-sleeve north fights confluence of short message technology, much sensor net of couplet of group net technology, content passes solution of technology of feeling technology, wireless communication, brim to calculate technology, cloud the burgeoning technology such as computational technology is hand-in-hand went to apply innovation, in order to satisfy the real requirement that the user monitors each fractionize domain in geological calamity safety. In get respect of message of geological change trends, the real time that can realize successive to target area long-term stability is monitored, accurate and comprehensive ground is gotten, record and analyse the data that monitor, come true thereby ahead of schedule, hidden trouble of calamity of ground of early-warning of choice accurate land, assist a government to be opposite processing, scattered, remove wait for plan to make scientific and advantageous decision-making; be in integral performance side, solved show automation of net of couplet of stage other people to monitor solution bulk bigger, cost taller, power comsumption is bigger, stronger to environmental dependence wait for pain spot problem, reduced traditional deformation to monitor the power comsumption of terminal and cost considerably, aid the deformation that pushs low cost, low power comsumption, high accuracy to monitor a product to monitor the application of the industry in ground calamity, high accuracy of class of contented millimeter monitors dimensions to change applied requirement.

Chip class north fights geological calamity to monitor integral solution

Real time is monitored - safety is monitored analyse cloud platform with early-warning

Combine other sensor, the ground calamity system that monitor is divided can come true successive real time exterior displacement is monitored outside still can be opposite other calamity element undertake monitoring, wait like pressure of displacement of moisture content of water level of rainfall, mud, underground water level, soil, deep, earth, earthquake sounds, infrasonic sound, accomplish truly round-the-clock all-around monitor. Once real time monitors index to reach early-warning value, the system can spark call the police, implementation classifications answer, fast linkage, decrease calamity to strive for more time and space for take precautions against natural calamities. Pass the executive deploy of this solution, can realize installation, monitor continuously, long-distance use dimension, overcame spot of environment of complex meteorological phenomena, project devious the influence that reachs traffic limitation, car of the artificial, time in can saving rush to repair of dimension of check of artificial make one's rounds, carry effectively to work, poor brigade and the cost such as the appliance that monitor.

The ground calamity that is located in area of and other places of Yunnan province, Guizhou Province monitors a station

Dimensions changes development nip in the bud

North fights satellitic navigation system to be carried out independently as our country, the global satellite navigation system that runs independently, can provide reliable high accuracy fixed position and time service service, security tall, technology is mature. Rely on north to fight technology of high accuracy fixed position " chip class " the demand that high accuracy deformation monitors a solution to will satisfy more application setting, if irrigation works is monitored, mine is monitored, bridge is monitored, key building is monitored, building radical hole is monitored, highway railway sedimentations monitor etc. "Chip class " the solution is in a lot of advantage of the respect such as function, power comsumption, cost, the dimensions that also is relevant applying is changed gain ground to popularize and be carried out laid good foundation. Drive north to fight " chip class " the solution turns application in the dimensions of the deformation domain that monitor, have the calamity risk that appears possibly for different domain better shifting to an earlier date early-warning, ensure safety of people life property better, also will be the restful China that builds higher level to contribute north to fight at the same time " core " force.
