Logging in management can choose " administrator logs in " or " anonymity logs in ", and administrator, which logs in, to be needed to input account password, there is control
Permission processed, the system of can control enter init state or operating status etc., and anonymity, which logs in, does not need input password, may only look into
See current device working condition, no control authority；
List of devices shows whether equipment on-line situation, i.e. equipment are switched on；
Control button control system enters different working condition；
Status display area shows current system working condition, respectively " initialization ", " in monitoring ", " alarm "；
Threshold value setting area can be set and show equipment monitoring deformation quantity threshold value；
Numerical value viewing area can show initial distance, real-time range and the type variable of three laser monitoring equipment institute measuring points.
9. the bridge supporting structure based on Internet of Things deforms round-the-clock monitoring method, it is characterised in that:
Before carrying out bridge supporting structure deformation monitoring, three laser monitoring equipment are fixed on phase on bridge frame bottom ground
The monitoring point answered levels laser monitoring equipment, presses " switch " button of control cabinet, activation system, and laser sensor projects
Red laser beats laser point in the position that needs monitor；
After fixing laser monitoring equipment, system is made to enter init state, three laser monitoring equipment read and remember respectively
Initial distance value is recorded, data are passed in control cabinet by cable according to RS485 agreement, control panel carries out analytical Calculation to data
Afterwards, the LCD screen of control cabinet is to show the currently initialization distance value for " initialization " state and three laser monitoring equipment,
Data are reported to by Cloud Server and/or mobile phone by GPRS simultaneously；
After pending data is stablized, system is made to enter monitoring state, three laser monitoring equipment read current distance value in real time respectively,
And passed in control cabinet by cable, after control panel carries out analytical Calculation to data, the LCD screen of control cabinet shows " monitoring
In " initialization distance value and the current real-time range value of state and three laser monitoring equipment, while will be in data by GPRS
Registration Cloud Server and/or mobile phone；
In monitoring process, current real-time range value is compared by control panel with initialization distance value, when data difference is more than set
When threshold value, i.e. triggering alarm device alarm, to realize Monitoring and forecasting system in real-time function, working condition becomes " alarm " at this time, and simultaneously
Display is on the lcd screen and/or on mobile phone；
Site safety person is according to the numerical value of three laser monitoring equipment judges the place gone wrong in LCD screen or on mobile phone.
