Wherein, L=2 bytes are taken here, and the T=30 seconds, Z=2T, then N is more than 50,000,000 data；Then according to calculating
The Z arrived size, it is 2T to set common PC computer hard discs capacity, and just enough 50,000,000 differential pressure transmitters retain its aging data.
Wherein, aging data actual use is mostly to store once for 1 hour, that is to say, that the data of enough 1,000,000,000 differential pressure transmitters use.
Common computer is even in this way, large server just more no longer is talked about.
Preferably, in the step (g), the mode that computing device sends information shows including being directly displayed at computing device
Sent in display screen and by communication unit, it, which sends out the object of feedback information, includes Web high in the clouds.
Preferably, by being merged with other process datas in differential pressure transmitter production process, composition is big in the Web high in the clouds
Data are analyzed with facilitating.
Operationally, user can check PLC to the PLC using any terminal that can be surfed the Net by webpage
The state of signal in controller, and the running situation of PLC this moment.If during emerged in operation failure, user is first
Can whether normal according to the input variable that PLC is checked from web monitor, where primarily determining that problem, designer
Also can remote assistance investigation problem.If user needs to change program, designer does not spend scene and can remotely changed.This
Sample, for administrative staff, it can pass through the feelings for the data that each differential pressure transmitter collection is directly obtained with Web high in the clouds
Condition.And for a user, also can by cloud device be connected each Terminal Type obtain in its authority check it is related
Data, it is easy to use, and the signal transmission of whole system is reliable, data will not lose.The system passes through data acquisition server
Carry out data integrity collection so that the system compared to it is existing by way of public machine directly carries out data acquisition for,
Cost is relatively low, is not in data transfer congestion, the situation of loss of data.
It should be understood by those skilled in the art that the embodiments of the invention shown in foregoing description and accompanying drawing are only used as illustrating
And it is not intended to limit the present invention.The purpose of the present invention completely and effectively realizes.The function and structural principle of the present invention exists
Show and illustrate in embodiment, under without departing from the principle, embodiments of the present invention can have any deformation or modification.
