Process and in transmission platform in data, before sending pending vehicle data to long-distance monitorng device, due to uncertain The concrete number of the pending vehicle data received, it is therefore desirable to pending vehicle data is formatted.If pending car The number of data is at least two, then need to be spliced by pending for this at least two vehicle data, according to preset rule Model rule formats process to spliced pending vehicle data；Wherein, preset specification rule is treated for described in specification Process the form of vehicle data.
S24. the described pending vehicle data after formatting being processed sends to long-distance monitorng device.
6. method as claimed in claim 5, it is characterised in that pending vehicle data is being carried out according to preset specification rule When formatting processes, it is first determined whether the quantity of this pending vehicle data is at least two, however, it is determined that this pending vehicle The quantity of data is at least two, then spliced by those pending vehicle datas, and to spliced pending vehicle number According to formatting process.During if it is determined that the quantity of pending vehicle data is one, based on described preset specification rule by institute State pending vehicle data and format process.
7. method as claimed in claim 6, it is characterised in that in order to the pending vehicle after successfully formatting being processed Data send to long-distance monitorng device, when sending the pending vehicle data after formatting to long-distance monitorng device, the most really Fixed send format after the transmission agreement of pending vehicle data, will pending after formatting based on this transmissions agreement determined Vehicle data sends to long-distance monitorng device.
8. method as claimed in claim 7, it is characterised in that in order to guarantee that data process and format in transmission platform Pending vehicle data after process all can send to long-distance monitorng device, the pending vehicle number after formatting being processed According to sending before long-distance monitorng device, the pending vehicle data after formatting being processed adds in transmission waiting list, This transmission waiting list pending vehicle data after storage formatting processes.
