ABSTRACT
Along with the mobile communication technology swift and violent development as well as the user quantity sharp growth, more and more has the research value using the mobile communication technology realization long-distance control. This article introduced uses SMS based on the GSM network the wireless long-distance monitoring terminal principle and its the simplification system design realization. It is composed by a wireless GSM module and take the monolithic integrated circuit as the core monitoring unit. The wireless GSM module took intermediary establishes the user handset and the monolithic integrated circuit control system long-distance correspondence through the transmission and the receive short note ,but the monolithic integrated circuit control system utilizes the AT instruction through the string mouth with the wireless GSM module establishment correspondence, achieves the realization system function the goal.
This system may apply through the improvement to production and life, its most prominent merit lies in it to be able to realize the accurate real-time twp-way communication, moreover because the GSM network cover scope is extremely widespread, Therefore this system the region environment influence, simultaneously regarding the user was not said this system operation extremely convenient, cost low, the benefit is high.
This article first in detail elaborated the monolithic integrated circuit short news receiving and dispatching system hardware composition and the design structure as well as the monolithic integrated circuit and the wireless GSM module connection way ,simultaneously also in detail introduced the short news control command and the short news receiving and dispatching protocol data unit form has carried on the elaboration. Finally discussed the function which the software partial structural design and can achieve.
