Definitions
- the present invention relates to a sensor head with a sensor element, the measurement signal of which can be fed to a comparator, by means of which the measurement signal can be compared with a threshold value and a binary output signal can be forwarded to a transmission circuit, a control module for at least two sensor heads and one consisting of a control module and at least one two sensor heads formed multiple sensor.
- Sensors by means of which a binary output signal can be transmitted to a higher-level control module, so-called binary sensors, are used for.
- B. used in automation in the automotive industry or in machine tool manufacturing in large numbers.
- the sensors are connected to the controller or a decentralized peripheral module either via conventional parallel wiring or via a fieldbus system.
- FIG. 1 A part of a parallel-wired system is shown schematically in FIG. It has a central unit 1 with an input / output module 2.
- the central unit 1 and the module 2 are connected to one another and to a power supply module 4 via an internal control bus 3.
- actuators e.g. solenoid valves
- Two sensors 5 are shown to represent all other sensors, for which only connections 6 are indicated symbolically.
- connection between the module 2 and the sensors 5 is generally made via a three-wire line 7. Two of these lines are used for energy supply, and the third signal is used to transmit the binary signal from the sensor 5 to the module 2.
- the sensors are provided with protective measures such as reverse polarity protection and short-circuit protection, but this is relatively expensive.
- each individual sensor 5 must be parameterized on-site by teach-in. If a sensor 5 becomes defective and has to be replaced, a new teach-in process is required, since the threshold value is only stored in sensor 5 itself.
- the sensors 5 can be based on different functional principles. For example, they can be optical sensors 5. In operation, optical sensors 5 generally only periodically emit a correspondingly short light pulse in a short time window. The time window is controlled by an internal clock stage. Even the emitted light is only recorded in this time window. However, since all sensors 5 work autonomously and are normally not synchronized or triggered, there may be mutual interference if the time windows of two sensors 5 coincide and a sensor 5 detects the light pulse from another sensor 5 (crosstalk). ,
- control pulses are transmitted to the individual sensors 5 from an additional control unit 9 via additional control lines 10. This allows the sensors 5 to be controlled in a staggered manner, so that crosstalk is practically impossible.
- a disadvantage of the construction according to FIG. 1 is that the so-called control access ends at the input / output module 2. This means that the central unit 1 cannot recognize if e.g. B. there is a sensor error or the line to sensor 5 is interrupted.
- FIG. 2 shows a control system similar to FIG. 1.
- the output signals are transmitted via a fieldbus 11, that is to say a two-wire line common to all sensors 5.
- the input / output module 2 is replaced by a fieldbus master 2 ', to which a separate fieldbus power supply 22' is assigned.
- the fieldbus 11 can operate according to the so-called AS-i protocol, for example.
- the fieldbus master 2 ' simply controls the data exchange between the central unit 1 and the actuators (also not shown in FIG. 2) and the sensors 5.
- the fieldbus master 2' does not preprocess and link data.
- the central unit 1 Due to the bidirectional data exchange between the fieldbus master 2 'and the sensors 5, it is in principle possible to transmit diagnostic information and parameter values, in particular the threshold values, in addition to the output signals. However, this must be controlled accordingly by the central unit 1. A targeted triggering of the sensors 5 is also possible in principle, but here too the central unit 1 must control this accordingly. In this case, the smallest possible trigger pulse interval the user program cycle time. Real-time object detection by sensors 5 is therefore practically impossible. As a result, the additional control unit 9 together with the additional control lines 10 must therefore also be provided in the implementation according to FIG.
- the object of the present invention is to create a multiple sensor and its components, namely a sensor head and a control module, by means of which an independent, flexible and comfortable operation of the individual sensors or sensor heads of the multiple sensor is possible in a simple manner.
- the object is achieved for the sensor head in that it can be supplied with electrical energy via a proprietary two-wire line, the output signal being able to be transmitted from the transmission circuit via the two-wire line to a higher-level control module external to the sensor head.
- the task is also corresponding with a
- Control module for at least two sensor heads solved in which the sensor heads can be supplied with electrical energy from the control module via proprietary two-wire lines, binary output signals from the sensor heads being able to be transmitted to the control module via the two-wire lines, the output signals being able to be forwarded to a higher-level central unit external to the control module.
- the multiple sensor then consists of a control module and at least two sensor heads, each of which is connected to the control module via a proprietary two-wire line.
- the output signal can be detected at defined times. If the reading of the binary output signals into the sensor heads with subsequent transmission to the control module can be triggered separately for each sensor head, the sensor heads can be triggered independently of one another. This makes it possible in particular to control the sensor heads at the same time or staggered in time.
- control module detects sensor errors, if after a predetermined period of time after triggering reading of the binary output signals into the sensor heads with subsequent transmission to the control module, the binary output signals have failed, an error detection is possible.
- the threshold value can be transmitted from the control module to the transmission circuit via the two-wire line, the threshold value can be set in a simple manner.
- diagnosis within the sensor head is possible along with transmission of the diagnosis to the control module.
- control module can also transmit the threshold value to the control module via the two-wire line, it is possible to teach in the threshold value only via one of the sensor heads and then to automatically forward the learned threshold value to all other connected sensor heads. If the transmission of information via the two-wire line is address-free, the data transmission is particularly efficient. The address-free transmission of information is possible because the two-wire lines are assigned to the respective sensor heads in a proprietary manner.
- the sensor element can be of any design. However, it is often designed as an optical sensor element.
- the two wires of the two-wire line can be connected without regard to the polarity.
- the sensor head can be designed particularly cost-effectively.
- the central unit can be relieved of data processing tasks and thus the cycle time can be shortened.
- FIG. 3 shows a control system with a multiple sensor
- FIG. 4 shows a sensor head
- a multiple sensor consists of a control module 12 and a plurality of sensor heads 13. Only three sensor heads 13 are shown in FIG. 3, but in principle the number of sensor heads 13 is arbitrary.
- the sensor heads 13 are connected to the control module 12 via proprietary two-wire lines 14. Via the two-wire lines 14, which are assigned to each sensor head 13 in a proprietary manner, both the sensor heads 13 are supplied with electrical energy and data are transmitted between the control module 12 and the respective sensor head 13.
- the control module 12 is connected to the central unit 1 and the power supply module 4 via the control bus 3.
- the central unit 1 is also connected to at least one output module 15 via the control bus 3. In the context of the present invention, however, this output module 15 is not important. Therefore, this will not be discussed further below.
- each sensor head 13 has two connections 16 for the two-wire line 14.
- a rectifier unit 17 is arranged directly downstream of the connections 16.
- the two-wire line 14 is short-circuited for a short time. So there is a voltage dip.
- the rectifier unit 17 is therefore followed by a voltage stabilizer 18.
- the voltage stabilizer 18 consists of a reflux blocking diode 19, a backup capacitor 20 and a choke 21. Because of the voltage stabilizer 18, a stable voltage supply to the other components of the signal head 13, namely a transmission circuit 22, a DA converter 23, a comparator 24, an amplifier 25 and a control stage 26 possible.
- Data transmitted by the transmission circuit 22 are read into a processing unit 34 via tap lines 33, each associated with a connection pair 31.
- the output of data to the respective sensor heads 13 takes place via switching elements 35 which can be controlled by the processing unit 34.
- control module 12 with a sensor head 13 is explained in more detail below in connection with FIG. 6.
- the functional principle explained for one sensor head 13 can of course be transferred directly to the other sensor heads 13. Due to the proprietary assignment of the two-wire lines 14 to the respective sensor heads 13, the data transmissions are also independent of one another.
- the triggering of reading in of a binary output signal described below can also be triggered separately with subsequent transmissions to the control module 12. In this case, simultaneous, staggered or purely stochastic control is possible in particular.
- the control module 12 transmits a trigger pulse 36 to the transmission circuit 22 from time to time by correspondingly actuating the corresponding switching element 35.
- the transmission circuit 22 then actuates the actuation stage 26. It therefore triggers reading of the binary output signal into the transmission circuit 22 and subsequently transmits the read output signal to the control module 12.
- an acknowledgment signal 37 is first transmitted in each case via the two-wire line 14 in accordance with FIGS. 6b and 6c. Depending on the value of the output signal, the two-wire line 14 is short-circuited again briefly after the acknowledgment signal 37 or not.
- the transmission circuit 22 is able, among other things, to carry out a diagnosis inside the sensor head.
- the transmission circuit 22 outputs a delayed acknowledgment signal 37 '.
- the control module 12 can thus distinguish between an error message from the transmission circuit 22 and a normal acknowledgment signal 37. If, on the other hand, no acknowledgment signal 37, 37 'is transmitted at all, the control module detects sensor errors after a predetermined, longer period of time after a trigger pulse 36. In this case, either the two-wire line 14 is interrupted or the sensor head 13 does not respond at all.
- the transmission circuit 22 transmits a pulse sequence 38 shown in FIG. 6e.
- the pulse sequence 38 is interpreted by the control module 12 as a request for the transmission of the threshold value.
- the control module 12 therefore subsequently transmits a sequence of counting pulses 39 to the transmission circuit 22 according to FIG. 6f.
- the number of counting pulses 39 results in the value to which the threshold value is to be set.
- the transmission of the threshold value can take a certain time. However, this is tolerable, since the transmission of the threshold value is generally only required when the sensor head 5 is started up.
- the control module 12 can also short-circuit the two-wire line 14 for a longer period of time 40, hereinafter referred to as long pulse 40.
- the transmission of such a long pulse 40 to the transmission circuit 22 is used by the latter as a request for the transmission of the already interpreted threshold value interpreted.
- the transmission circuit 22 then transmits a sequence of counting pulses 39 'to the control module 12 as shown in FIG. 6h.
- the threshold value can again be given by the number of counting pulses 39'.
- the threshold value is set directly in the sensor head 13, e.g. B. via the button 8, it is thus possible to set this once in a sensor head 13, then transmit it to the control module 12 and then transmit the threshold value from the control module 12 to the other sensor heads 13.
- the output signals transmitted to the control module 12 are further transmitted from the control module 12 to the central unit 1.
- the control module 12 determines an effective sensor signal for each sensor head 13 on the basis of the output signal transmitted by this sensor head and at least one further output signal previously transmitted by the same sensor head 13. This allows short-term faults to be effectively recognized and filtered out.
- the control module 12 determines an effective sensor signal for each sensor head 13 on the basis of the output signal transmitted by this sensor head and at least one further output signal previously transmitted by the same sensor head 13. This allows short-term faults to be effectively recognized and filtered out.
- only the last output signal, which was transmitted directly beforehand, or further output signals can also be used.
- the sensor signals can optionally be further evaluated by the control module 12.
- the sensor signals can e.g. B. logically linked with each other and the link result to the central unit 1. For example, from a signal follow two sensor heads 13 to the direction of rotation of a shaft and only this direction of rotation signal, ie an increment, are passed on to the central unit 1.
- the signals can also be checked for plausibility and the result of the plausibility check can be forwarded to the central unit 1. If, for example, a sensor head 13 is assigned to a travel element with respect to each end position, if the sensor heads 13 and the travel element function properly, both sensor heads 13 must not simultaneously detect the presence of the travel element. If this is the case, there is an error that can be recognized by this plausibility check.
- the sensor head 13 can be operated in a diagnostic manner, in which the lighting or Laser diode 27 a threshold value is determined, at which the output signal is just 1. When the limit threshold value is increased by 1, the output signal becomes 0. In this diagnostic mode, the strength of the measurement signal and thus indirectly the quality of the sensor element 28 can be detected. In the case of an optical sensor element 28, for example, the quality of the optics and / or contamination of the optics can be deduced.
- This diagnostic operation is preferably only initiated by the control module by transmitting an appropriate command.
- the further diagnosis is carried out automatically by the transmission circuit 22. Only the limit threshold value is transmitted back to the control module 12.
