FIELD: radio engineering, communication.
SUBSTANCE: invention relates to technological process control systems. A communication system comprises a wireless power supply and communication unit (100, 200, 300, 350, 360, 400) configured to be connected to a field device (14) and to provide operating power and wireless digital communication between the unit (100, 200, 300, 350, 360, 400) and the field device (14). An electronic high-frequency device (366) in the unit (100, 200, 300, 350, 360, 400) is configured for radio-frequency communication. In one version, a power source (365) in the unit includes one or more solar cells (116) which convert solar energy to electrical energy for powering both the unit 100, 200, 300, 350, 360, 400) and the field device (14). The unit (100, 200, 300, 350, 360, 400) interacts with the field device (14) according to a standard industrial communication protocol. The unit (100, 200, 300, 350, 360, 400) is wirelessly connected to an external device, e.g., a control station (12), based on interaction with the field device (14).
EFFECT: broader capabilities of monitoring a technological process.
