Description

Locating and operating device for buried fittings

The invention relates to a control and actuation device for a valve arranged on a line running under the floor, in particular on a pipe line for a hydraulic medium, e.g. a servo valve, a gate valve, a shut-off valve, with one from an energy source, e.g. a generator, a power supply system, an actuator of a drive device for a locking element of the fitting, which can be controlled by an energy means, and a control and / or monitoring device for actuating the drive device and the condition monitoring of the fitting, as well as a method for controlling and actuating one a valve running under the floor, arranged armature, eg a servo valve, a shut-off valve, a shut-off valve, in which an actuator of a drive device for a locking element of the valve is supplied with energy by means of an energy release means, an energy means and an energy absorption means.

EP 0 200 535 A1 discloses a checking system for an underground control device, for valves to be controlled from the surface of the earth, with devices for transmitting signals to the control device and with devices for detecting the operating state of the control device. Also known from this document is a control station which communicates wirelessly with the control device from the surface for controlling the valve, the devices for identifying the valve and addressing the signals to a specific one

Has valve of a valve system.

From US 5,813,655 A a wireless, remotely controllable valve arrangement for a water pipe is known, the valve arrangement having a main valve with a hydropower-operated actuator and one with a power source, in particular a battery

Energy-supplied secondary valve which can be actuated via a signal transmitter is provided, via which the actuator of the main valve is operated with pressurized water from the water line for actuating the main valve.

The object of the invention is to provide a control and actuation device for a valve arranged under the floor in a line system for a medium, with which the actuation of a valve from a number of valves with a location-independent energy source and independently of the surface intended fixed installed Facilities and is achieved without direct line connections and which allows control of the switching states of the valve.

This object of the invention is achieved independently in each case by a control and actuation device mentioned at the outset, in which a transmission device for the energy medium from the energy source and by an energy delivery means which is connected to the energy source and is arranged at a distance from it and is connected to a control unit of the drive device Energy absorption means is formed, or by a method mentioned at the outset, in which a control device of the fitting is first supplied with energy wirelessly by the energy means from an energy delivery means via an energy absorption means, and then a clear identification signal is output by the control unit, which signal is sent to a control unit. and / or control device is transmitted. The surprising advantage here is that, starting from a single energy source in a spatially unlimited area, fittings arranged in a line system can be specifically controlled and monitored without the need for disruptive devices on the surface. It is thus possible to control any desired fitting with a single mobile control and / or monitoring device without having to carry electrical or mechanical elements from the fitting to the surface of the earth. As a result, these elements are largely protected from external influences and damage, and operation of the valve by unauthorized persons can also be prevented. It is also advantageous that irrespective of the type and structure of the valve, control and energy supply can take place with a single control and / or monitoring device and that it is not necessary to carry several different tools or the like.

It is also possible for the control unit to be functionally connected to a plurality of drive devices from a plurality of fittings, which has the advantage that, on the one hand, the expenditure on electronic components is minimized by sharing a control unit from a plurality of fittings and, on the other hand, with spatially close arrangement of several Ren fittings or combination fittings a safe assignment or location of the

Control unit can take place and no mutual influence of several closely arranged control units is possible. According to a further development, according to which the control device is designed with a transmitting and / or receiving device for detecting and transmitting state variables of the fitting and / or the control device, this information can be transmitted in a simple manner to the control and monitoring device without interference from the energy means respectively.

According to a further development, it is possible for the control device to be functionally connected to sensors which are designed to record and transmit information about the status of the actuator and / or the position of the blocking element and / or to query operating and environmental conditions, for example. whereby the user can determine the current position of the locking element in a simple and safe manner, and a check can be carried out immediately as to whether, for example, a desired movement of the locking element is carried out by the actuator or whether data relevant to operation can be recorded and transmitted.

It is also possible that the energy absorption means is designed with a transmitting and / or receiving device for receiving and / or sending state variables of the fitting and / or the control device and / or that the energy delivery means is designed with a transmitting and / or receiving device for receiving and / or Sending of state variables of the valve and / or the control device is formed, whereby the advantage arises that the already existing energy delivery or energy absorption means can be used for an information or data exchange and therefore no additional antennas have to be provided.

If the control and / or monitoring device with a transmitting and / or receiving device for receiving and / or sending state variables of the valve and / or the

Control device is formed, there is the advantage that this information can be transferred to the control device in a simple manner without interference from the energy means.

Because a first energy storage element is assigned to the energy absorption means, it is advantageously possible that energy transmission, for example to the drive device of the fitting, does not have to be continuous and at a high level in accordance with the power requirement, but firstly a buffering of the energy by the energy Giespeicher can take place and with a sufficiently large amount of stored energy, for example, the actuator can be driven and the locking element can be opened or closed without interruption.

A further development, according to which the first energy storage element is designed as an electrical or mechanical energy storage element, for example a capacitor, battery, spring, provides a cost-effective design and a design which is relatively insensitive to external influences and at the same time has a long service life.

Because the control unit contains a non-volatile and / or a volatile data storage element, data which serve, for example, to identify the fitting, or also data which have basic parameters, for example the necessary energy requirement or the like, can be stored permanently in the control unit State variables, which are detected by additionally arranged sensors, are temporarily stored in the data storage element and, when the communication link is established with the control and / or monitoring device, are read out and transmitted as a data packet and are sent for further processing or evaluation.

It is advantageous if the control unit contains at least one microprocessor and / or microcontroller, since this already allows, for example, preprocessing of the sensor data recorded or also the integration of energy management for the charging process of the energy storage element or the drive of the drive device.

According to a further development, it is possible for the control device to be assigned a further energy storage element, as a result of which the control device can function independently of the drive device or of the first energy storage element, thereby ensuring a secure energy supply even when the drive device is subjected to high loads.

According to a further development, it is advantageous for the transmission device to be designed for a contactless and / or wireless energy flow, since this makes the

Transmission device, is also given with regard to the control of several different slide elements. A further development, according to which the energy delivery means and the energy absorption means are designed for an inductive energy flow, has the advantage that energy transmission can also take place over large distances with a high energy density, as a result of which, for example, the charging time of an energy storage element can be kept short.

According to a variant, according to which the energy delivery means and the energy absorption means are designed for a capacitive energy flow, the advantage arises that an energy transfer can take place with little construction effort and thus low costs.

It is also possible that the control and / or monitoring device is designed to receive location signals, for example GPS signals, since this makes it possible in a simple manner to find predetermined coordinates of the desired fitting in a simple and quick manner.

Because the actuator is connected to an actuator, preferably with a spindle, for the locking element of the valve in the drive connection, on the one hand there is high mechanical stability and on the other hand a spatial distance between the locking element and the actuator can be bridged in a simple manner.

It is also possible for the energy source and the energy delivery means to be arranged on a vehicle, since a high degree of flexibility is thereby achieved.

According to a further development, the energy delivery means can be arranged on a lifting device, whereby a simple and energy-saving placement at the desired position is possible for the user.

According to a development of the method, it is advantageous if the energy means supplies a first energy storage element with energy, as a result of which, for example, the actuator can be continuously supplied with energy after the first energy storage element has been charged, and thus a switching operation of the valve without repeated engine starts, as would occur, for example, in the event of interruptions in the direct energy supply to the drive. It is possible that the amount of energy transferred is monitored and the power supply is interrupted after a sufficient amount of energy has been reached for a switching operation of the valve, which has the advantage that an optimal cycle time is achieved in such a way that no unnecessarily long charging process takes place, but immediately after of the correct state of charge, the valve can be switched.

Furthermore, it is possible for the control and / or control device to roughly locate the control device or the energy consumption means by means of location signals, for example by means of GPS signals, so that the desired fitting can be found easily and quickly by the user with high accuracy.

The fact that control signals or status variables of the fitting and / or of the control device are transmitted wirelessly between the energy delivery means and the energy absorption means has the advantage that the minimum distance between the transmitter and receiver of the data results in a high signal strength and thereby reliable reception the data is possible.

According to a variant, according to which control signals or status variables of the fitting and / or the control device are transmitted wirelessly between the control and / or control device and the control device, there is the advantage that information can be transmitted to the control device in a simple manner without interference from the Energy resources can be made.

According to a further development, according to which the energy delivery means or a locating device of the control and / or control device is used for fine locating of the energy receiving means by means of radio signals, there is the advantage that a high positioning accuracy is achieved and thereby a high degree of efficiency in the transmission of the energy means is achieved is and thereby the charging time of the energy storage element can be shortened.

The fact that the oscillation frequency of the electromagnetic waves of the energy means is less than 30 kHz, preferably less than 20 kHz, gives the advantage that the low absorption rate or the high depth of penetration enable long ranges to be achieved with a simultaneously low power consumption of the transmitting or receiving unit are. The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

Show it:

Figure 1 shows a control and actuation device according to the invention in a simplified, schematic representation.

Fig. 2 shows an embodiment of the control and actuation device.

In the introduction it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, the disclosures contained in the entire description being analogously applied to the same parts with the same reference numerals or the same component designations. The location information selected in the description, e.g. above, below, laterally, etc. refer to the figure described and illustrated immediately and are to be transferred analogously to the new position in the event of a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

1 shows a control and actuation device 1 for a line 2 or line system, in particular for a hydraulic medium, which is laid under the floor, according to arrow 3. The hydraulic medium can be water or oil, for example. The line 2 is assigned to a fitting 4. Lines 2 laid in this way usually run in the field to protect the line system, in particular also for reasons of frost protection, at a distance 5 from a corridor surface 6, which can be between 0.5 meters and 3.0 meters. Depending on the geographical location, there must be a distance 5, which is above the frost limit.

The armature 4 is, for example, a slide valve 7 with a housing 9 forming a flow channel 8. A blocking element 10 for blocking until the flow channel 8 is completely released is arranged therein. For this purpose there is a drive device 11 provided with an actuator 12 and with this drive-connected, rotatably mounted in the housing 9, actuator, which is preferably designed as a spindle 13, which is provided with an external thread according to a preferred embodiment and cooperates with an internal thread of the locking element 10.

In the exemplary embodiment shown, the actuator 12 is an electric motor 14 fastened to the housing 9 of the fitting 4, preferably a geared DC motor 15.

Furthermore, a control device 16 is arranged on the armature 4 or the electric motor 14, which is connected to the electric motor 14 via a switching means 17 and has a transmitting and / or receiving device 18 for wireless signal transmission with a transmitting and / or receiving device 19, which is preferably arranged in a mobile control and / or monitoring device 20 operated via a corridor.

A transmission device 21 is provided to supply the electric motor 14 with energy, to carry out an adjustment process of the actuator 12 and thus to adjust the blocking element 10 in order to block or release the flow channel 8. This consists of a preferably mobile energy source, for example a battery or a generator 22, which can be integrated in a vehicle 23 and for example via the electrical system of the power tool 23 or directly from one

Drive motor of the motor vehicle 23 is operated. Furthermore, the transmission device 21 has an energy supply means 24 which is in line connection with the generator 22 and an energy absorption means 25 which is line-connected with the control device 16 on the fitting 4 and which is located under the floor at a distance 26 from the floor surface 6 which can be selected depending on the nature of the floor is positioned. A direct contact between the energy delivery means 24 and the energy absorption means 25 is not necessary since the energy transmission, according to arrow 27, takes place contactlessly or wirelessly. The energy release means 24 or the energy absorption means 25 can be formed by large-area coils or capacitor plates.

The control and / or monitoring device 20 serves to control the control device 16 on the fitting 4 arranged under the floor. The control and / or monitoring device 20 can be integrated in a control and / or control console 30 which can be connected in the vehicle 23 or in a portable and / or via a line 28 for energy supply at an interface 29 provided on the vehicle 23.

However, there is also an operation independent of the vehicle 23 by means of its own energy supply, e.g. possible with a battery 31. The control and / or control device 20 or the control and / or control console 30 can be arranged with a power supply, for example a rechargeable battery 31, in its own, conveniently portable housing, and is connected to the power supply means 24 by a line.

The control and / or control console 30 is equipped with corresponding operating and / or control elements 32, e.g. Pushbuttons, switches, indicator lamps, displays, etc., as required for the operation of the control and actuation device 1, are provided.

The energy release means 24 can be arranged for easier handling on a lifting device 33, which allows the manipulation thereof.

It is also possible for the energy delivery means 24 to be designed as a compact, mobile and portable unit, as a result of which simple and effective use of the control and actuation device 1 is possible even in rough terrain and can easily be carried out by a single person.

The energy supply or energy transmission between the energy delivery means 24 and the energy absorption means 25 of the transmission device 21 can take place according to the principle of inductively coupled transponder systems, that is to say by means of a transformer coupling.

In order to locate the desired fitting 4, a rough location, for example by GPS location signals, can be carried out by the control and / or monitoring device 20. The necessary coordinates of the armature 4 or the control device 16 are determined once when the armature 4 is installed and can be saved in a corresponding database. This rough location allows the position of the fitting 4 to be determined with an accuracy of <5 m. Since it is advantageous for energy transmission between the energy delivery means 24 and the energy absorption means 25, which is positioned at a distance 26 below the floor, if their positions correspond as closely as possible, after the rough location has been carried out, the energy absorption means 25 can be finely located by radio signals or by induction. ons measurements take place.

These radio signals or the induction measurement can be transmitted by means of a locating device 34. For example, a signal strength of a location signal reflected or returned by the energy absorption means 25 is located, which signal is emitted by the location device 34, which is preferably guided on the corridor surface 6. A reaction of the voltage induced by the energy release means 24 into the energy absorption means 25 and the current resulting therefrom can also be measured.

It is also possible that radio signals from the transmitting and / or receiving device 19 arranged on the control and / or monitoring device 20 are received by the energy absorption means 25 or the transmitting and / or receiving device 18 and used for fine location.

To operate the transmission device 21, a magnetic field is first generated in the energy output means 24 by a large-area coil, which serves as an antenna. The emitted electromagnetic field penetrates the ground and the antenna coil of the energy absorption means 25 and induces an electrical voltage in the coil. In the same direction, this voltage can also be used to supply energy to the control unit 16.

If the energy delivery means 24 is now guided over an energy absorption means 25, a voltage is generated in the coil of the energy absorption means 25 by the field of the coil of the energy delivery means 24, which voltage is initially used to activate the control device 16. The control unit 16 reads its own identification from the non-volatile data storage element by means of the microprocessor and transmits this identification signal to the energy output means 24. It is also possible for the identification signal to be transmitted to the transmitting and / or receiving device 18 by means of radio signals / or receiving device 19 of the control and / or control device 20 is transmitted. In an embodiment variant, it is possible for a separate locating device 34 to make the first contact with the energy absorption means 25. For this purpose, the locating device 34 likewise has a coil which induces a voltage in the energy absorption means 25.

It is possible that the signal strength on the control and / or control console 30 is represented graphically by suitable operating and / or control elements 32, also in a kind of two-dimensional map, so that it can be seen by the user in a simple and quick manner in FIG Which area of the area defined by the rough location is the energy absorption means 25 of the desired fitting 4.

In order to avoid difficulties in finding the desired fitting 4, for example in the presence of a plurality of fittings arranged close to one another or to ensure the selection of the correct fitting 4 from a group of fitting fittings 4 belonging to a combination fitting, the control unit 16 emits an identification signal, which is sent to each individual Armature 4 is clearly assigned and this signal is transmitted to the energy output means 24 or to the location device 34 or the transmitting and / or receiving device 19.

In the event of positive identification of the desired fitting 4, a charging process of a first energy storage element 35 assigned to the energy absorption means 25 can first take place. This charging process can be controlled by the microprocessor of the control unit 16 in connection with a non-volatile data storage element in such a way that the efficiency is optimized or only that amount of energy is transmitted from the energy delivery means 24 to the energy absorption means 25 that is necessary to switch the locking element 10 by means of a switching operation the drive device 11 of the armature 4 to perform.

The first energy storage element 35 can also be designed as a mechanical spring, for example, and energy can be transferred from the energy delivery means 24 to the energy absorption means 25 and further to a motor drive that is functionally connected to the spring, in order to tension the spring and the energy stored thereby to operate the Control unit 16 and the valve 4 are used. In a preferred embodiment variant, the transmission device has a resonance frequency <30 kHz, preferably less than 20 kHz.

The energy transfer of the energy means can take place inductively, but it is also possible to use a capacitive coupling.

The transmission of information, for example to the control unit 16 from the control and / or monitoring device 20, can take place by means of high-frequency radio signals. Furthermore, it is possible for an oscillating circuit to be formed in the energy absorption means 25, the resonance frequency of which is matched to the transmission frequency of the energy delivery means 24. The clock frequency of the microprocessor or of the memory can also be derived from this induced AC voltage. Likewise, the efficiency of the energy transmission can be increased in the energy delivery means 24 by increasing the resonance in the resonant circuit, as a result of which a strong magnetic field can be generated.

The first energy storage element 35 is supplied with the energy until a sufficient amount of energy is available for a switching operation of the fitting 4. Then the charging process is interrupted and the desired switching process takes place. During or after the switching process, relevant data, such as the current position of the locking element 10, information about the operating state of the actuator 12 of the drive device 11, and further sensors 36, which, for example, the direction of flow of the medium in the line 2, the temperature of the Medium, its pressure, flow rate, etc. recorded.

These sensor data are recorded by the control unit 16 and, if necessary, preprocessed by the microprocessor or stored in the storage device and transmitted to the transmitting and / or receiving device 19 by means of the transmitting and / or receiving device 18. The desired commands are entered by the user using the control and / or control console 30 and these commands are transmitted wirelessly from the transmitting and / or receiving device 19 to the transmitting and / or receiving device 18 and to the control device

16 forwarded. This data can also be transmitted by means of the energy release means 24 and the energy absorption means 25. FIG. 2 shows a further and possibly independent embodiment of the control and actuation device 1, the same reference numerals being used for the same parts as in the previous FIG. 1.

Shown is a transmitting and / or receiving device 19 integrated in the energy delivery means 24 and a transmitting and / or receiving device 18 integrated in the energy receiving means 25.

Relevant data can be recorded by several sensors 36, as already described under FIG. 1, and these are forwarded to the control unit 16 for further processing.

It is also possible for the control device 16 to be assigned a further energy storage element 37, as a result of which the control device 16 or its microprocessor and / or microcontroller and memory can operate independently of the energy of the first energy storage element 35, thereby increasing reliability or making it more stable Signal transmission is coming. The charging process of the further energy storage element 37 takes place as described under FIG. 1, for example by induction.

It is also possible for data to be transmitted directly between the energy release means 24 and the energy absorption means 25, both full and half duplex methods being able to be used here. A higher-frequency data signal is superimposed during the energy transmission.

It is also possible that, for example, in the case of a combination fitting or the presence of several fittings 4 and locking elements 10, which are functionally connected to several actuators 12 and electric motors 14, the control device 16 only for those selected on the control and / or control console 30. Armature (s) 4 with the corresponding identification signal detects the corresponding information or executes commands.

For this purpose, the control device 16 is connected to a line 38 with all fittings 4 belonging together. The energy supply takes place via a common energy absorption means 25, the data transfer via a transmitting and / or receiving device 18 takes place. The data from the sensors 36 of the further fitting 4 are recorded by the common control device 16.

The exemplary embodiments show possible design variants of the control and actuation device 1, it being noted at this point that the invention is not restricted to the specifically illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this possible variation due to the Teaching on technical action through physical invention lies in the knowledge of the specialist working in this technical field. The scope of protection also includes all conceivable design variants which are possible by combining individual details of the design variant shown and described.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the control and actuation device 1, these or their components have been partially shown to scale and / or enlarged and / or reduced.

The object on which the independent inventive solutions are based can be found in the description.

Above all, the individual designs shown in FIGS. 1 and 2 can form the subject of independent solutions according to the invention. The relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
