Definitions

  • the invention relates to an apparatus and method for detecting and / or regulating and wirelessly transmitting measurement and / or control data from a machine component to e.g. a monitoring system of a papermaking machine.
  • Wireless systems require wireless data transmission and wireless power transmission for such applications.
  • Wireless data transmission has long been state of the art, such as from the DE101 04 582 A1 known.
  • the demand for a wireless power supply usually leads to a solution with battery or battery operation.
  • the plant operator can not be expected to cyclically (e.g., annually) replace hundreds of batteries on the many sensors and / or actuators.
  • From the DE101 04 582 A1 is known to be produced by means of a pyroelectric crystal responsive to a temporal change in temperature ⁇ T with charge separation energy.
  • a pyroelectric crystal can be used as an energy source but only if the temperature at the measuring point or in the immediate Environment changes constantly. This is not the case with papermaking plants in the stationary state.
  • a pyroelectric crystal is not suitable for many applications to generate sufficient power to supply, for example, actuators with energy.
  • the invention is therefore based on the object, a device and a method for low-cost and low-interference detection and / or rules and transfer of measurement and process data to show in a machine or production plant to a control system.
  • a device for detecting and / or regulating and for transmitting measurement and / or control data in a machine or production plant to a control system, with at least one subsystem, with at least one connected sensor and / or actuator and a power supply proposed.
  • the subsystem consists of at least one data acquisition and control unit, a microcontroller, a transmitting and receiving unit and an antenna.
  • a wireless connection is present and that for energy supply, a power generation module is present that uses a non-electric energy source for power generation.
  • the power generation module for utilizing the non-electric power source is a thermoelectric generator that converts a heat flow into electrical energy.
  • a thermoelectric generator TMG
  • TMG thermoelectric generator
  • the subsystem is arranged according to the invention in a housing which is mounted near the site of the sensors / actuators within the system / machine. It must be ensured that between the contact surfaces of the thermoelectric generator heat flow can take place.
  • the one contact surface of the thermoelectric generator is heat-conductively attached to a surface on the system.
  • This surface preferably has a stable temperature potential.
  • a bearing of a roller which is heated by the roller work and optionally tempered by a lubricant flow.
  • it is the surface of a pipeline with the medium at a different temperature than the environment.
  • the other contact surface of the generator must have thermally conductive contact to another temperature potential, such as the temperature potential of the ambient air, a liquid, or a component, which is exposed to thermal radiation.
  • the second contact surface may also be connected to a heat exchanger which is in good contact with the ambient air or a liquid.
  • Thermoelectric converters are based on the Seebeck effect. With today's TEG, an energy yield of about 10 W with a module area of 40x40 mm and a differential temperature of 100 ° C can be achieved. However, with such high module outputs, water cooling is usually required to maintain the differential temperature. Modules with a lower power of 1-2W per module can also be operated via convection. Since the available space is limited near the sensors / actuators and in individual cases with very small temperature differences of a few degrees Celsius is expected, but you have to make do in reality with relatively small benefits. Investigations have shown that the temperature differences on a paper plant in the vicinity of sensors / actuators in the range of 4 ° to 60 °. For example, it is warm in the area of the dryer section, but at the measuring points for monitoring systems, the actual temperature difference between the bearing and the environment is still relatively low.
  • a rechargeable accumulator or a capacitor, or another rechargeable voltage source is located in the subsystem. This is loaded by the TEG and the data transfer is activated only when the state of charge is sufficient. In practice, this is achieved by a cyclic operation. For example, load 100 time cycles, perform 1 time cycle actions.
  • the sensor / actuator can optionally be provided with an additional voltage source and the operation of the sensor / actuator can optionally also be cyclical.
  • a memory module can be provided so that no data of the subsystem is lost.
  • the wake-up module allows energy-saving, cyclical operation of the subsystem. This means that the majority of the subsystem is usually inactive. The wake-up module activates these inactive parts as needed. The wake-up module has a clock or the possibility to interpret messages received accordingly.
  • the power generation module and / or the antenna and / or the at least one sensor / actuator can be connected to the subsystem via a cable connection.
  • this cable connection will of course be so short that no protective tubes are required.
  • a method for detecting and / or regulating and transmitting measurement and / or control data, in a machine or production plant to a control system, with at least one subsystem, proposed with at least one connected sensor and / or actuator and a power supply wherein the measurement and / or control data from the subsystem, comprising at least one data acquisition and control unit, a microcontroller, a transmitting and receiving unit and an antenna are detected, the measurement and / or control data from the subsystem to the control system and / or a another subsystem is made by means of a wireless connection and that a power generation module is used for the power supply of the subsystem that uses a non-electrical energy source for power generation.
  • the wireless connection is preferably via WLAN, although all other wireless connections can be used.
  • the proposed device or method can be used in many places of a machine or plant, such as e.g. for measuring temperatures and / or pressures and / or flow rates and / or positions and / or vibrations at or in the area of the rolls of a paper plant, even within rotating components, or also for measuring and controlling temperatures at or in the area of bearing points.
  • the Fig. 1 shows the basic structure of a subsystem 1 with all components that may contain this.
  • the subsystem 1 comprises at least one data acquisition and control unit 6, a microcontroller 7, a transmitting and receiving unit 8, a power generation unit 3 and an antenna 5 and a sensor / actuator 12.
  • the antenna 5, the Sensor / actuator 12 may also be connected via a cable connection to the subsystem 1.
  • the microcontroller 7 controls the processes, the data processing, controls communication tasks, performs calculations, and reduces the amount of data by appropriate compression.
  • the subsystem may additionally include an accumulator 2, which also makes it possible to provide larger amounts of energy. This is necessary when actuators are to be controlled, which generally require a multiple of the energy of a sensor, or when the energy of the power generation unit must be cached.
  • a memory module 5 such as a RAM or Flash
  • data such as the configuration data, measured data, Communication data and control data can also be cached and so the possibility exists to separate the measurement and the data transmission from each other in time.
  • the clock can also be used for a timing of the processes and the actuators or as a time stamp for a measurement.
  • an amplifier module can additionally be integrated in the subsystem 1, as well as a filter for filtering the signals if, for example, the measurement noise is too high.
  • Fig. 2 is exemplified a housing 13 of a subsystem 1 outlined.
  • the overall housing 13 is divided into two sub-housings 13a / 13b.
  • the sub-housing 13 a all essential components are included as well as the thermoelectric generator 15 and a heat conductor 16, which can be continued outside the housing 13.
  • An antenna and / or a power supply can also be connected to the sockets 5 outside the housing.
  • the sockets 14 are provided.
  • the sub-housing 13a is attached to the surface of a system in a heat-conducting manner. It is not thermally conductively connected to the sub-housing 13b.
  • the heat flow is passed through the TEG 15 and the heat conductor 16.
  • the heat conductor 16 is on the side of the housing 13b with a different temperature level than on 13a in combination. This can be done by ridges on the housing 13b, which serve as a heat exchanger with an air flow or water flow. Or through a connection to a component that receives heat radiation.
  • Fig. 3 is the overall system 18, for example, a monitoring system shown.
  • the subsystems 1 are with each other and / or with the control system node 26th connected to each other via a wireless connection 19.
  • the wireless connection 19 is preferably via WLAN.
  • a concrete application example shows the Fig. 4 , Here is a roller with a roller bearing 20 shown in the example, the temperature of the bearing to be monitored.
  • the sensor here a temperature sensor
  • the subsystem 1 is attached to a surface 21.
  • the housing 13 of the subsystem is attached to a suitable surface 21, so that the largest possible temperature difference to the environment is available for generating energy by means of a thermoelectric generator and so enough energy can be generated.
  • the surface 21 may be, for example, the housing of a bearing, a stiffener, a motor, a roller surface, a foundation rail, or the like.
  • a heat sink can be attached to the housing 13 b, or a body with a large surface area, which provides a good thermal contact with the ambient air through the large surface. Or it can also be a planar element attached to the housing 13 b, which is heated by radiated heat of an adjacent component. Or a body that provides contact with a liquid, such as a heat exchanger.
