Native system is the power transmission tower frame design for the high altitude localities, is narrated to the course of work of system and in conjunction with the requirement of supervisory system below in conjunction with Fig. 1.
Supervisory system is considered the wireless transmission flow, the factor such as power consumption and cost, native system do not adopt in real time and send, and namely gather and once send to far-end server once, but adopt Real-time Collection, timed sending or fixed point to send or the program request observation, the specific works process is as follows:
The first step: the unloading phase
After light fibre humidity transducer I2, fibre optic temperature sensor I3, light fibre humidity transducer II10 and the fibre optic temperature sensor II11 networking and after installing, starting, carry out initialization, wireless communication module also can enter into configuration mode namely by master controller CPU1 simultaneously, wireless communication module is sent the AT order carry out corresponding configuration.Configuration namely begins receiving data information after finishing, and wireless communication module also is connected with Long-distance Control PC6 with port numbers by the address of the Long-distance Control PC6 that sets simultaneously.Be connected to after the Long-distance Control PC6, wireless communication module can send a packet, and packet the inside comprises pylon device id number, the information such as device name, and these information also can be presented on the interface of Long-distance Control PC6.The user just can send some collection transmission control commands as gathering the orders such as size, frequency and request transmission data to gathering front end this moment, front end adjusts accordingly terminal after receiving order, and send current temperature, humidity data information sends to Long-distance Control PC6, Long-distance Control PC6 record, preserves and monitor being connected of this front end and server.At this moment, the WEB page that can open Long-distance Control PC6 can be seen the renewal of data.
Second step: automatic detection-phase
After startup is finished, on the WEB page of processing remote control PC6, can show data message, and when temperature, humidity information gather, constantly monitor the variation of these two information, when ponding appears in moisture absorption water tank 5, send one-level and report to the police.Temperature reaches below 0 ℃, when humidity to 90% is above, sends secondary and reports to the police.Temperature rises to more than 0 ℃, or humidity is removed alarm condition less than 90% the time.
Native system also comprises some other function:
1, timed sending function
Timing function is realized by the master controller CPU1 of sense terminals in native system.Be that master controller CPU1 regularly sends current data message once to wireless communication module 4.The timing setting is realized by the function that arranges of Long-distance Control PC6 end.In the time period of the impossible generation icing such as summer, can close detection system, save power.
2, fixed point sending function
Send once to Long-distance Control PC6 end by wireless communication module 4 when temperature arrives certain point, the fixed point that arranges in the native system is :-10 ℃, and-3 ℃, 0 ℃, 3 ℃, 10 ℃.
3, program request sending function
When the user without the regularly requirement of monitoring, perhaps the timing that arranges of user is longer, perhaps arrive the time that fixed point sends, but has in the middle of fixed time interval in the requirement at the scene checked, the user can the start-up point multicast function.By sending the order that request sends to processing terminal, the temperature at current scene, humidity just send Long-distance Control PC6 end at Long-distance Control PC6 end.
The utility model describes by specific implementation process, in the situation that do not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
