The Design And Implementation Of SMS Platform For The Prison System

In the jail serves a prison sentence the personnel and the outside relation communication is generally uses the relative to visit prisoners or the telephone way. Because the relative visits prisoners to have the effectiveness, the telephone communication needs the guardianship personnel's monitor, thus these two contact method cannot use massively. The short note service is through the storage repeater, the real-time monitor mechanism, provides reliable, the low expenses, the point-to-point wireless data communication service, the user does not need the paper and writes down the record, the content may store up and may momentarily consult the information. Therefore, so long as completes the short note content examination work, the short note way can realize the serving a prison sentence personnel and relative's effective interaction, thus promotes the serving a prison sentence personnel's thought transformation.This article attempts the GSM Modem short note receiving and dispatching function and the computer formidable memory, the management function unifies, designed and has realized one face the jail user, based on the serial port correspondence short note platform system. The system is composed of three parts: Short note input subsystem, short note examination subsystem and short message service center. The serving a prison sentence personnel may through the short note input system edition and the examination short note, the administrative personnels to transmit using the short note auditing system carry on the content verification with the receive short note, the short message service center control GSM the Modem transmission and the receive short note.This article first to SMS the definition, the principle of work, the characteristic and so on carried on introduced that then has carried on the analysis to the jail short note system's demand, and has carried on the introduction to the system flow and the system database's design. The computer and between the GSM Modem correspondence is realizes system's key and the difficulty, is also this article key point, mainly includes using the system API function realizes the computer and the GSM Modem serial port correspondence; Realizes using at instruction to GSM Modem each kind of control and the short note receiving and dispatching operation; Transmission and receive short note PDU (Protocol Data Unit) form analysis. This article has given system's realization finally.This system already installed the use in many jails, the movement good shape, has met user's need.
