Definitions

  • the invention relates to an automation system with a control device for controlling a processing device, in particular a manufacturing device, with at least one sensor for transmitting sensor data from the processing device to the control device.
  • the invention further relates to a sensor according to the preamble of claim 9.
  • Such an automation system is, for example, a manufacturing device or an automation system in the field of building, packaging or storage technology.
  • sensors are required which, for example, determine the position of certain parts of the processing device and forward them to the control device to initiate any necessary control measures.
  • the sensors are either wired directly to the control device or via a data bus to the control device.
  • the invention has for its object to reduce the effort involved in the installation of sensors.
  • the sensor data are transmitted via a radio interface from the transmitting device of the sensor arranged at the location of the processing device to the receiving device arranged at the location of the control device.
  • a transmission in the opposite direction, i.e. from the control device to the sensor is made possible in a simple manner in that the radio transmission device and the radio reception device of the sensor are each designed as combined radio transmission reception devices, the radio reception device arranged in the area of the processing device for receiving control data for controlling the sensor is provided.
  • a reduced hardware expenditure for connecting a plurality of sensors is ensured in that the radio receiving device is part of the control device and has means for receiving the sensor data of one or more sensors.
  • the receiving device is part of a radio reception module which is provided for receiving the sensor data of several sensors and can be coupled to the control device directly or via a data bus connection.
  • Secure data traffic via the radio interface of the sensor is ensured in that the data protocol transmitted for data determination between the radio sensor and radio module has a first data area for identifying the identification of the sensor and a second data area for identifying the sensor data to be transmitted.
  • the Data protocol transmitted between the radio module and the sensor has a first data area for identifying the identification of the sensor and a second data area for identifying the control data to be transmitted.
  • the effort for transmitting the sensor data can be kept low by insisting that the sensor data and / or the control data consist of binary signals.
  • the data area required for this can, for example, also be only one bit. In this case, two states 0 and 1 can be identified.
  • the amount of wiring required to operate the sensors can be further reduced in that the energy required for the power supply to the transmitter of the sensor is transmitted by electromagnetic radiation, in particular from the control device to the sensor.
  • FIG. 1 shows a first exemplary embodiment of a basic illustration of an automation system
  • 2a shows a data protocol for a transmission of sensor data from a radio sensor to a radio module
  • 2b shows a data protocol for a transmission of control data from a radio module to a sensor
  • 3 shows a second exemplary embodiment of an automation system
  • 4 shows a further embodiment of an automation system with connection to a data bus
  • FIG. 5 shows a further exemplary embodiment of an automation system with a central data bus radio module.
  • the automation system essentially consists of a processing device, for example a manufacturing device 2, and a control device 1 for controlling the manufacturing device 2.
  • Sensors 3, 4 are provided in the area of the manufacturing device 2.
  • the sensors 3, 4 are used to record sensor data, for example measurement data relating to the positioning of certain parts of the production device 2.
  • the sensors 3, 4 each have a radio transmission device 8 which transmits the sensor data determined by the sensor 3, 4 via a radio interface 6, 7 transferred to the automation system 1.
  • the automation system 1 has a sensor receiving part 5 with a radio receiving device 9, which is also referred to below as radio module 5.
  • the receiving device 9 serves to receive the sensor data transmitted via the radio interface 6, 7, which are then further processed in the automation device.
  • a connection line 16 indicates that the control device 1 can be connected to the processing device 2 for an additional data exchange.
  • the main task of sensors 3, 4 is to transmit determined sensor data, for example the position of a valve closed or open, as binary information, ie zero for open and 1 for closed, to control device 1.
  • the transmitting device 8 and the receiving device 9 are designed in such a way that a combined transmitting / receiving part is provided, so that bidirectional data traffic via the radio Interfaces 6, 7 is made possible.
  • the possibility of communication from the control device 1 to the production device 2 makes it possible to request the sensors 3, 4 to transmit their measurement data, ie their states, to the control device 1. So that a specific selection of a specific sensor 3, 4 is possible, specific identification identifiers are assigned to the respective sensor, which enable the respective sensor 3, 4 to be clearly identified.
  • the sensor 3, 4 can, for example, directly transmit the sensor data to the control device 1 via a duplex channel. If the sensor data is transmitted via a separate radio channel, the sensor 3, 4 first sends an identification code before transmission of the actual sensor data, which enables the measurement data to be assigned to the corresponding sensor 3, 4 (see FIG. 2b).
  • the advantage of creating a binary radio sensor 3, 4 is that no wiring is required for the installation of the sensors 3, 4 for a data connection between the processing device 2 and the control device 1.
  • the power supply required for the energy supply to the sensors 3, 4 can be provided either via solar cells, optionally in combination with an energy storage device such as an accumulator, a capacitor, etc.
  • FIG. 2a shows the basic illustration of a data protocol 10, 11 which is used to transmit the sensor data 11 from the sensor parts 3, 4 arranged in the area of the processing device 2 to the reception module 5 arranged in the area of the control device 1 (see FIG. 1).
  • the data protocol 10, 11 consists of a first data area 10 for identifying the identification of the sensor 3, 4 and one second data area 11 for identifying the sensor data to be transmitted.
  • the first data area 10 has a four-digit identification code II ..14, which makes the respective sensor clearly identifiable.
  • the second data area contains in particular sensor data S1 .. S3 consisting of binary numbers, which represent, for example, certain position data of the production device 2.
  • FIG. 2b shows a data protocol 12, 13 analogous to FIG. 2a, which is transmitted from the control device 1 via the radio interfaces 6, 7 to the sensors 3, 4 of the processing device.
  • Identification information II..14 is again contained in a first data area 12, while the second data area 13 contains control data AI..A3.
  • the control data 13 are used in particular to request the sensor to deliver current sensor data.
  • Such a targeted addressing of a sensor has the advantage that the radio transmission device of the sensor transmits sensor data to the control device only when necessary. The energy consumption of the radio transmission device can hereby be reduced to a minimum.
  • the automation system in turn essentially consists of a processing device 2 and an associated control device i.
  • sensors 3, 4 are again provided, which can be connected to radio modules 5 via radio interfaces 6, 7.
  • the radio modules 5 are arranged in the area of the control device 1 or connected to it.
  • radio modules 5a, 5b are provided in the exemplary embodiment shown in FIG. 1.
  • the sensor part 3 arranged in the area of the processing device communicates via the radio interface 6 with the receiving device 5a, while the sensor part 4 communicates with the radio module 5b via a radio interface 7.
  • FIG. 4 shows a further embodiment of an automation system.
  • the automation system consists of a processing device 2 and a control device 1.
  • sensors 3, 4 are provided which communicate with a radio module 5 via radio interfaces 6, 7.
  • the radio module 5 is coupled to a data bus 14, which is connected to the control device 1.
  • the data bus 14 is, for example, an actuator sensor interface which is known in the field of production automation and which is used primarily for the transmission of measurement signals.
  • other sensors etc. can also be connected to the data bus 14, which is not shown in FIG. 4 for reasons of clarity.
  • FIG. 5 shows a fourth exemplary embodiment of an automation system, which in turn essentially consists of a control device 1 and a processing device 2.
  • a data bus 14 is provided in accordance with the exemplary embodiment in FIG. 4.
  • a data bus radio module 15 is coupled to the data bus 14, with sensor / actuator radio modules 5 with transceiver devices 9 being connected to the data bus radio module 15.
  • the sensor-actuator radio module parts 5 communicate via radio interfaces 7 with the sensor parts 2, 3, 4 arranged in the area of the processing device 2, which also have transmission / reception parts 8.
  • the advantage of the architecture shown in FIG. 5 is that the connection of the sensor or control data to be transmitted via the radio interfaces 7 takes place centrally via the data bus radio module 15. The effort for connecting the sensor parts 5, 6 is thus reduced.
