Provided is an on-vehicle device which can deal with any of two systems (an active system and a passive system) used in a communication between road and vehicles, to provide an on-road apparatus and to provide a communication system between road and vehicles. The on-vehicle device scans the downlink of the active system, and it scans a frequency band used in the passive system. When the electric-field strength of received radio waves is a preset lower-limit value or more, the on-vehicle device is regarded as having marched into the communication area of the on-vehicle apparatus, and its frequency is stored (S110 to S130). When the stored frequency belongs to a frequency band exclusively used in the passive system, a passive communication part is immediately started, and a communication by the passive system is started. When the stored frequency belongs to a frequency band used in common by both systems, the active communication part is first started, and a communication by the active system is tried. When the content of a received signal cannot be analyzed, the passive communication part is started so as to be changed over to the communication by the passive system (S140 to S190).

The invention discloses a data handling method and a system in database to solve the problem that the single course treatment requires great amount of time and manpower cost and can not handle abnormities in ETL process. The method includes: arrange data synchronous configuration table and data refreshing configuration table; configuration information of the corresponding data source, start up a plurality of synchronous courses in parallel; refreshing grades, and start up a plurality of refreshing courses to make sequential synchronous and refreshing treatment on a plurality of data sources. The invention also includes parallel monitoring treatment; periodically checking synchronous refreshing information table; any abnormity discovered should be recorded in the alarm information table; the invention also includes parallel alarm treatment: Periodically checking alarm information table; alarm information should be sent immediately for new abnormities. The invention enhances the efficiency of synchronization and refreshing and saves a great deal of time and manpower cost. Real-time monitoring ensures timely handling of problems and safe, reasonable, and stable operation of database.

The invention relates to a system and method for synchronizing discrepant data of a common domain between databases. The method includes the steps that the discrepant data are read, related configuration information of a data table is inquired according to discrepant data information, and a first search condition is generated according to the related configuration information; whether the discrepant data exist or not is searched for at the common domain of the two databases according to the first search condition, and accordingly search results are recorded; baseline information of the discrepant data is inquired according to the discrepant data information, and a second search condition is generated according to the baseline information; a stored record of the discrepant data is searched for in a baseline library according to the second search condition, a needed SQL statement is formed according to the second search condition and the searched stored record of the discrepant data in the baseline library, and the data of a non-baseline library are modified through the formed SQL statement by using the record of the baseline library as the baseline. By the adoption of the system and method, data synchronous processing effectiveness is guaranteed, data synchronous accuracy is improved, and mistakes and hidden risks caused by negligence of operators are reduced.
