PHM module is responsible mostly for car fueling, petrol stations and related things.

Common terms:

• AVP - device for refueling (diesel, oil …). There are two types of AVPs - old one AVP31, new one AVPs - AVP41
• Fuel stations - can have more AVPs

Data flow:

• Synchronization - fuel stations, vehicles.
• Mostly synchronization writes into PHMTransaction table.
• Import is from many places e.g. KupsonView etc.
• These transactions are then processed via TransactionManager into transaction data store - PHMTransactionDataStore table.

Processing in TransactionManager

• reads amount of transaction from PHMTransaction process these amount in loop
• process vehicles, drivers
• process nozzles from transaction: save record from transactions into PHMNozzleHistory table

Synchronization:

On some customers with AVPs, method KupsonManager.SynchronizeAllDevices - there is both direction synchronization:

• information about AVP devices into our db - PHMTransaction
• information back to AVPs - mostly chip numbers, cards.

Time intervals for synchronizations are newly defined in db - PR

Photos:

Transactions has photos made by some cameras on fuel stations. These photos are synced via rsync to APL_Service server (name in Terminals) in shared directory \\192.168.148.15\avp\AGROFERT\201801\overphoto\cam_R691_8.jpg. These are then synced with some service into db - table PHMTransactionPhoto.
