As a brand-new technique, the “3S” techniques has already been widely accepted and applied broadly in many professions. But take a wide view of the application in each profession currently, the level is somehow low, and the area is not very wide. Many scholars are all concentrated on how to extend the applied realm of “3S” techniques that is very challengeable for them. By the amalgamation of the mobile communication, SCM and “3S” techniques, a widely used, easily transplanted and intact scheme is provided in this paper.
Compared with the traditional “3S” data, the data that the electric power pipeline monitor system acquired have some new characteristics: Such as the smaller amount of data tile; the strict time request of the data; the requirement for the geography position (but not all the monitor point are ambulant, So the immovable monitor point has lower request to the geography position), also the observed data is different from the traditional “3S” data, which emphasize particularly on the micro-information.
In the traditional “3S” platforms, RS has always been the geography data source, GPS is the way of solving the problem of the position, and GIS has resolved the problem of the data analysis and releases. But the three kinds of techniques have neglected the data transmission. In the traditional application, people also usually neglected the problem of data transmission, and they often use the general way, such as U disk, moving hard disk and etc., or use the traditional internet way to transmit data. The disadvantage of these traditional ways of data transmission is that long time to consume, and the dependence on manpower. Therefore we can see that the adoption of Mobile Communication to transmit data is a kind of beneficial complement to the traditional GIS.
Using this system, it not only solves the request of the electric power profession, but also has good all-purpose ability and adaptability. Other realm can easily use it. The main advantages of this system are:
2. Integration of mobile communication and “3S” techniques
- Using the Mobile Communication technique, and the monitor system can complete the data collection and transmission very well.
- By using the SMS technique, the system is good at not only the data transmission but also the processing of the data.
- Lower system expenses.
- Operating easily, inexpensive, carrying out the auto monitor.
- Based on the mobile communication net, there are stronger stability and safety.
- Using the sensor and SCM technique, it has stronger pertinence.
- The system is much more agile to change, can adapt the requests of different professions.
2.1 Introduce of mobile communication technique
Great developments have taken place in the mobile communication technique since the 1970s. Nowadays it has developed from 1G to 3G(tab.1). GSM belongs to 2G. It has the most abroad overcast, highest reliability, strongest safety, and becomes one of the best mobile communication net. Using GSM as the wireless data-transmitting platform of our system can insure the safety of the information transmission. The system mainly uses the SMS operation of the GSM net. In addition, the SMS operation can transmit faster, have lower costs, and easily to upgrade the system.
