2, insert protection.The SIM that the communication module of acquisition terminal is used just as the I.D. in the social life, can be confirmed a user's identity uniquely; For informatization security, this has just had the basis of safety certification, can carry out the characteristic of identification; Business application system is passed through ID authentication mechanism; All information of sending or transmit through application platform are carried out addresser's authentication, in service application, judge validated user identity (SIM is bound, the white list technology) through the registration phone number; The unique identity of guarantee information and the reliability of content realize the access security protection of system.
3, system realizes grading authorized management function to the user, through inspection user's name and licencing key, gives the user and operates power accordingly, and the Password Management mode confinement unrelated person of using for reference banking system changes database and hardware setting.
4, firewall functionality and perfect data backup function, the defence system receives artificial malicious attack, the data backup function guarantees when the hardware system fault, also can be at any time on new hardware device data do not have and start kilowatt meter reading-out system with losing.
Fig. 4 indicated data communication transmission process process flow diagram
Fig. 4-1 indicated data communication transmission process process flow diagram.It is following that far-end acquisition terminal and GPRS between the monitoring central server are connected flow process:
GPRS just often, long distance wireless data transmission module terminal, base station adopts GPRS to send data, monitoring central server loopback GPRS response message is confirmed.
During the GPRS fault, long distance wireless data transmission module terminal, base station adopts SMS (note) mode to send data, and monitoring central server does not need return response information to confirm.
When GPRS recovered, system's GPRS mode commonly used again transmitted data.
Fig. 4-2 indicated data communication reconnects treatment scheme.If if GPRS connection failure in addition, system can start GPRS and reconnect mechanism:
GPRS reconnects machine-processed meeting repeating transmission in per 30 seconds after failure, if sent failure (when promptly not receiving confirmation) in continuous 10 minutes, module can be carried out reset operation, avoids system's entering endless loop or system to hang waiting status.
Carrying out each module initialization after the system start-up earlier handles; Carry out GPRS then and connect login; Acquisition terminal is regularly made a copy of the consumption freezing data on the same day, and (so-called freezing data is meant particular moment ammeter record electricity consumption data first; No matter when checking meter all is those data constantly, rather than real time data.So just can have correct time at interval, as from 23 daily power consumptions being exactly power consumption from zero point to 23 on the 23rd days 24) and store.Carry emergency battery in the acquisition terminal, when power-off condition takes place, in time power cut signal is sent by the reserve battery power supply, transmission finishes, and the terminal gets into dormant state automatically.Because the image data that had a power failure also again.When civil power is sent a telegram here, starting terminal, and send electric signal to system immediately.The reporting system power supply has recovered normal.
System's characteristics:
1. back-up source cuts off the power supply and preserves data automatically;
2. power load can be set, and supports overload to report to the police;
