Definitions

  • the invention relates to a field device according to the preamble of claim 1.
  • field devices are often used to measure a process variable in a process.
  • Field devices for flow, level, differential pressure, temperature determination etc. are generally known. They are used to record the corresponding process variable mass or volume flow, fill level, pressure, temperature etc.
  • the field devices each generate measurement signals that are a measure of the measured process variable.
  • the measurement signals are usually forwarded to a control room or a control system. As a rule, the entire process is controlled from the control room or from the control system, where the various measurement signals from different field devices are evaluated and control signals are generated for other field devices (actuators, e.g. valves) that control the process flow.
  • the signal transmission between field device and control room or control system takes place z. B. via a current loop or a digital data bus according to the known standards (Profibus, Foundation Fieldbus, CAN bus).
  • the individual field devices are usually scattered over a wide area in larger production plants. If a problem occurs with a field device, e.g. Sensor failure or a process alarm, a corresponding message is issued in the control room or in the control system. The exact location of the field device in question is usually problematic. The operator in the control room has to search the corresponding site plans and pass the information on to the service technician on site.
  • a problem occurs with a field device, e.g. Sensor failure or a process alarm
  • a corresponding message is issued in the control room or in the control system.
  • the exact location of the field device in question is usually problematic.
  • the operator in the control room has to search the corresponding site plans and pass the information on to the service technician on site.
  • the object of the invention is therefore to create a field device that is easy to locate.
  • the essential idea of the invention is to integrate a GPS module in the field device.
  • FIG. 1 shows a field device according to the invention.
  • a field device F known per se is shown in FIG.
  • the field device F has a sensor SE which detects a process variable (e.g. pressure temperature or flow).
  • the analog measurement signal is converted by an A / D converter A / D into a digital measurement signal and fed into a microprocessor S.
  • a control program is stored in various parameters (eg calibration factors) in a non-volatile memory SP which is connected to the microprocessor S.
  • the non-volatile memory SP can be, for example, an eprom, an (e) eprom, flash memory or a chip.
  • an input / output unit I / O is connected to the microprocessor S, which essentially serves to display the measured value and for manual input.
  • the microprocessor S communicates via an interface K1 with a control room or a process control system (not shown in more detail). Communication can take place via a data bus or a serial bus. Communication takes place according to the well-known standards (Hart, Profibus, Foundation Fieldbus, CAN-Bus). The microprocessor S is still connected to a GPS module.
  • the GPS module provides location information that enables the field device to be located with sufficient accuracy in a production plant.
  • the location information can e.g. passed on to the control room or control system via the data bus. Based on this location information, the field device is easy for the service technician to find on site.
  • the GPS module has a transmitting device that transmits the location information by radio.
  • the location information is only used relatively rarely, it makes sense to activate the GPS module only when necessary. This means that the additional power consumption in the field device is reduced to a minimum by the GPS module. In principle, it is only necessary to activate the GPS module in the event of an error or alarm.
  • a GPS module also provides precise time information, this can be used as a time stamp for an error message or an alarm message.
  • the error message or alarm message is sent to the control room or control system together with the time stamp.
  • the location information can also be used to create an exact map of individual field devices.
