Description
Technical field:
The present invention relates to a kind of cruising inspection system, particularly relate to a kind of mobile phone based on Android system and patrol and examine terminal system, belong to the transmission system technical field between institute's use electronic equipment in daily life and work.
Background technology:
" three collection five are large " that current national electrical network is carried out mainly refers to: human resources, finance, goods and materials intensive management; Huge construction program, large construction, large operation, general overhaul, large marketing system.In " three collection five are large " Shi State Grid Corporation of China development strategy, propose, implement two transformations: change development of company mode, change power network development mode.According to grouping of the world economy running, intensivization development, lean management, Standardization Construction (being called for short " Four Modernizations ") requirement, implement human resources, finance, goods and materials intensive management, build huge construction program, build greatly, large operation, general overhaul, large marketing (being called for short " three collection five are large ") system, realize development of company mode and change.Since implementation three collection five are large, power transformation O&M teams and groups function changes: " grasp power transformation operation "+" Maintenance and Repair business "=" O&M is integrated ".In the process to the integrated transformation of O&M, exist personnel few, website is many, and facility information amount is large, maintenance work increases, and makes an inspection tour Quality Down, and required technical ability increases, technical support is not in place, and work mobility is large, field data cannot rapid feedback etc. a series of problem.
At present the integrated on-site data gathering of O&M comprises and patrols and examines terminal system, data communication module system and background management system with feedback patrolling and checking management system, patrols and examines terminal system and consists of the mobile phone of Android system.Patrol and examine terminal system and have two kinds with the swap data method between background server: data are synchronizeed and data transmission.The two-way exchanges data of the synchronous support of data, guarantees the function that two end datas are identical.Meanwhile, comprise anti-collision settlement mechanism: data transmission is also supported two-way exchanges data.But the not function for guaranteeing that two end datas are identical, also not conflict solution.And system applies requires under many circumstances, same data can be carried out multiple spot modification when patrolling and examining terminal in off-line state, complete afterwards server sync, so need to comprise conflict, solve function, to process the concurrency problem occurring when terminal turns back on line state with synchrodata of patrolling and examining disconnecting.
Summary of the invention:
Technical matters to be solved by this invention is: provide a kind of mobile phone based on Android system to patrol and examine terminal system, complete the integrated on-site data gathering of O&M and feed back the general management of patrolling and examining.
The present invention is that the technical scheme that technical solution problem is taked is:
A kind of mobile phone based on Android system is patrolled and examined terminal system, comprise that RFID patrols and examines terminal data acquisition system, described RFID patrols and examines terminal data acquisition system and comprises RFID middleware unit, RFID anticollision unit, RFID security mechanism unit and analyze Mobile data library unit
1. RFID middleware unit:
RFID middleware is the interlude of realizing data transmission, filtration and Data Format Transform between RFID hardware device and application system, it is the maincenter unit of RFID application deployment running, it is between reader/writer module and application system, the various data messages that rfid interrogator is read, through middleware extraction, deciphering, filtration and format conversion, import management server, and be reflected on program interface by application system. for viewer, browse, select, revise, inquire about;
2. RFID anticollision unit:
When RFID patrols and examines the work of terminal data acquisition system, read write line there will be conflict when two or more electronic tags send data simultaneously, it is data collision, thereby cause the read write line can not sense data. reduce work efficiency, adopt packet bit time slot A LOHA algorithm, by utilizing bit time slots to replace frame slot, realize that label is single to be read;
3. RFID security mechanism unit:
Comprise the protection of personal user, enterprise customer's individual privacy and secret of the trade, with RFID, patrol and examine the attack-defending that terminal data acquisition system is carried out, the method for using Key value to upgrade Random Hash lock solves the safety problem in RFID utilization;
4. analyze Mobile data library unit:
(1) first in database, create and comprise H-Key, ID, Key, the data-base recording of these 4 row of Pointer, major key is H-Key;
(2) lock tag: reader is chosen a numerical value at random as the Key value of label ID, and sets up original records H-Key in database, ID, Key, 0, the Key value that tag storage receives enters lock-out state;
(3) release label: database produces a random number R and sends reader to, by reader, apply for information Query and R are sent to label: label calculates H-Key and H-Key ‖ R loopback reader according to the R receiving and self Key value, calculates voluntarily subsequently H-ID ‖ R and Key
*=S-key;
(4) reader is searched data-base recording: if find, record i:H-Key
