Definitions

  • the invention relates to a shield control device of a Ausbauschildes for carrying out the expansion functions of the Ausbauschildes (expansion unit) in longwall construction in a mine.
  • This control is z. B. known by the DE 103 93 865.6A1 ,
  • the individual expansion units referred to in this application as: shield or Ausbauschild, from a central control device or by the individual control units, which are assigned to each of the shields (shield control devices) or be controlled by an operating device via radio for data transmission.
  • Each shield control device has for this purpose a microprocessor with memory for storing the shield control device associated code signal (Schildcodewort).
  • the data transmission within the shield comprises the electrical communication between the shield control device and the functional elements (actuating magnets and sensors) of the respective expansion plate, in particular firstly the delivery of control commands to the force transmitter of the expansion plate, which are in particular the actuating magnet of the respective hydraulic valves for actuating the force transmitter Second, the retrieval / request and the transmission of measurement signals of the sensors, which are assigned to each extension plate, for example for pressure measurement of the force transmitter or inclination measurement or position of the components of the expansion plate. From each shield control device from the adjacent or several adjacent shields can be controlled to issue commands or to retrieve measurement signals.
  • all signals ie, the delivery of commands (command signals), the request for measuring signals (recall signals) and the measuring signals themselves, in this application: control signals fed to all shield control devices via a line common to all shield control devices (bus line).
  • the shield controllers are programmed to only address the shield controller and cause it to execute the control signals associated with the shield codeword sent with the control signal. All other shield control devices pass the control signal with shield codeword.
  • This invention addresses the problems of data transfer of the blade control device within each expansion shield.
  • the shield control device must hitherto for data transmission connection means, so electrical cables and multicore cables to a plurality of functional elements, said functional elements are partially combined in groups, e.g. the solenoids of combined in blocks hydraulic valves, and the other part are identical or at least similar.
  • the laying of these electrical cables and cables within the Ausbauschildes is not only difficult, consuming and prone to error, it is connected during operation with the risk of damage.
  • the shield control device of a Ausbauschildes known in soft as functional elements of each of the control valves is mounted on the associated force transmitter and also contains its own valve control.
  • a peculiar to the respective control valve code word is stored in a memory of the valve control .

By means of a control command sent by the blade control, only that valve control is addressed and actuated in the sense of the work function of the associated control valve to be triggered, whose peculiar code word is identical to the code word associated with the control command
  • the object of the invention is an embodiment of such a shield control device, in which the cost of the wiring is largely reduced and limited to the absolutely necessary cable.
  • each expansion unit has a valve control device which is connected to the plurality of electrohydraulic valves having as many number of conduits 20 (p.9, paragraph 2).
  • the embodiment according to the invention has the advantage that within the shield control device of each extension screen, the electrical data transmission for carrying out the expansion functions, ie: the electrical data transmission for retrieving measurement signals of the sensors, the electrical data transmission for transmitting the measurement signals and the electrical data transmission for transmitting actuating commands to the actuators, can be made by the internal connection means with little cabling overhead within the Ausbauschildes. Therefore, the shield control and the wiring of the shield can be largely prefabricated, so that line faults due to incorrect wiring or subsequent damage largely are avoidable.
  • a code signal (address code word) valid only for this functional element is assigned to each of the functional elements of the expansion shield.
  • This makes it possible to carry out locally the function of the call (activation) of a specific functional element, which has hitherto been carried out centrally in the shield control device, locally.
  • This distributor can be connected to the shield control device as in the embodiment according to claim 2- via only a cable with few wires. It contains a microprocessor with memory as well as switching devices with individual switching elements, by means of which the connection to the called and to be activated functional element is made or interrupted via the internal connecting means.
  • a so-called call code word for a particular functional element of the shield is sent to the microprocessor of the distributor of the shield control device via said cable, it is compared in the microprocessor with the stored in the memory address code words. If the call code word and the stored address code word coincide, the switching device is actuated by the microprocessor in the sense that the connection for signal transmission between the shield control device and the functional element whose address code word is identical to the call code word is established.
  • connection means for data transmission between the distribution device and the functional elements are produced by a respective cable for each of the functional elements. Only a distributor with a microprocessor and switching device is needed. By the switching elements of the switching device, the connection to each of the connected functional elements can be made depending on which Rufcodewort has been previously sent by the shield control device to the Verteilêt.
  • the lines can be essentially inside the Distributor arranged and thereby protected against misplacement and damage.
  • This embodiment is particularly suitable when the functional elements are the actuating magnets of the hydraulic valves of the expansion plate and the data transmission of the transmission of control commands to the actuating magnet is used with the preferred embodiment according to claim 5.
  • the distributor is spatially located in or at or near each of the functional elements. It comes in this embodiment as a connecting means with only one cable for data transmission between shield control device and the first of the functional elements.
  • the functional elements may be connected to each other by a common bus line, which transmits the control signal to all functional elements, but in or on each functional element, a microprocessor with a switching device. is arranged, which transmits the transmitted control signal to the called functional element and this activated in the sense of the control signal.
  • the hydraulic valves are combined in one or more valve blocks in the further embodiment according to claim 6.
  • a command cable with at least two wires for the transmission of setting commands is sufficient.
  • the distribution device also contains the microprocessor with memory for the
  • Address codes and the switching devices by which -in accordance with the incoming Stellbetation- the one solenoid whose address code corresponds to the called call code, is acted upon by the electrical energy required for its adjustment via internal cable connections.
  • the distributor is and the switching devices are provided with a single electrical line with e.g. 12 volts connected.
  • the functional elements are the sensors of the hydraulic valves of the Ausbauschildes and the data transmission of the transmission of measuring signals of the sensors to the shield control device and to the external control devices is used (claims 7 and 8), the sensors are connected to each other in series by a measuring cable (bus line) and with the Shield control device connected by a single signal cable.

  • the signal cable is connected to the measuring lead by means of the switching means of that sensor, so that the Measuring signal is transmitted to the shield control device.
  • the bus line to the next sensor is interrupted. If the call code word of the first sensor connected directly to the shield control device does not correspond to the address code word sent by the shield control device, the bus line to the next sensor is closed by means of the switching device of this sensor, or the switching device remains in this closed position.
  • the interrogation and comparison procedure then takes place in this next sensor with the result that possibly the bus line is connected to the measuring line of this sensor, so that the measuring signal of this sensor is transmitted to the shield control device and the bus line to the next sensor is interrupted.
  • the same process can also happen as follows:
  • the switching devices of all sensors are located in the common bus line and, in the unloaded position, keep the connection between the sensors permanently closed.
  • a call code word sent by the shield control device thus reaches all the sensors or the microprocessors contained in them.
  • the microprocessor of that sensor whose address codeword stored in the memory of this sensor corresponds to the sent call codeword actuates the
  • Switching device connects the measuring line of this sensor with the data cable, so that the measurement signal is transmitted to the shield control device.
  • the bus line to the next sensor is interrupted.
  • the measuring signal of the sensors is constantly on.
  • the sensor may be equipped with a measured value memory from which the measured value can be retrieved when the polling code is transmitted by the actuation of the switching device.
  • the measuring signal can also be continuously measured by the sensor and the current measured value can be retrieved from the sensor when the polling code is transmitted by the actuation of the switching device (claim 8 ).
  • Control devices and-among other things-Shield control devices for a number of functional elements which make the traffic with one of the functional elements dependent on the correspondence of the address code word with a call code word have the advantage that the functional elements have to be of any type and need not be adapted to the control device.
  • this also has the disadvantage that functional elements with unreliable function can be used.
  • Another object of the invention is both for the shield control devices according to the preceding claims as well as other control devices of this type. In such control devices must be ensured that only design-appropriate and thus safe functional elements can be used. This is especially important for underground mining safety.
  • connection means for signal transmission between the control device and the functional element and microprocessor whose address code word is identical to the code signal (call code word) which can be sent by the control device, can only be activated if, in addition to and together with the call code word, the control device additionally uses a type for the type Function element characteristic code signal (type code word), which is stored in the memory of the microprocessor of each functional element according to its type, is sent.
