- a face control 33 is assigned to each group of extensions or Schiid controls.
- One each the shield control units 34 are assigned to one of the extensions 1-18 and connected to the pilot valves 45 and main valves 44 of all the power transmitters of the extension units 1, 2, 3 ... (is 18) via a valve control 40 (microprocessor).
- Each of the shield controls serves as a central expansion control.
- a face control 33 or also the entirety of the anti-fatigue controls, a central expansion control (main control center 50 and / or auxiliary center 51), which is connected to the anti-fatigue controls, can be superordinate to a group of several anti-fatigue controls.
- Such an embodiment is shown in Figure 2.
- the central expansion control consists of the main center 50 and the auxiliary center 51.
- Cable 58 (bus line) connects all shield controls 34 to one another.
- the expansion instructions are passed on via each skid control.
- the Ausbeubefehi a certain expansion function z. B. triggered in the sense of robbery, striding, setting This expansion command is received and passed on by monkey protection controls 34 via bus line 53.
- All removal commands of one of the longwall controls are fed directly to the shield control connected directly to the longwall control 33. From this shield control, the expansion commands then arrive via the bus line 58 to all other shield controls 34.
- only one of the fatigue controls 1-18 or a group of Activation control activated to carry out the respective expansion functions.
- the activated shield control then converts the received removal command into valve control commands to the control valves or main valves assigned to the affected extensions.
- the automatic triggering of the functions and functional sequences is described, for example, in DE- ⁇ 1 19546427.3.
- the control device 37 which is designed as a hand-held device and is carried by the operator, serves for the central manual operation of the command input. To enter the command, the operator can stand outside the strut or at least away from the current dismantling location.
- the handheld device is connected via radio to the radio receivers 38 of the face control devices 33.
- the rectangular handheld device has control buttons on one side (control side). These keys can also be used to enter the code of the expansion control to be operated (one of the anti-skid controls 34.1, 34.2 ...) and an expansion command to trigger a desired function or a desired functional sequence (e.g. robbing or walking).
- the antenna 39 of the handheld device is used for radio transmission.
- the control side of the handheld device When the operator turns the handheld device 180 ° around its longitudinal axis, he sees the control side of the handheld device.
- This is equipped with two diodes, a display and other buttons.
- the operator can light up the two diodes with his head amp. Only if it covers one of the diodes.
- the control function of the handheld device is triggered, for example with a finger.
- the operator enters the code of the removal to be checked.
- the hand-held device connects via an infrared transmitter / receiver 35 to a coordinated infrared transmitter / receiver 36 at the face control 33 addressed by code. Certain functions or operating states can now be queried using one of the buttons.
- a program is stored in the face control with which a sequence of queries about functions, operating states and functional sequences of a particular shield (removal) can be directed to the shield control addressed by code and carried out.
- the data received are then transmitted to the handheld device by means of the infrared transmitter / receiver 35, 36 and shown on the display. In this way, the sedentary can see whether a particular expansion is still fully functional or whether maintenance or the replacement of functional elements or Controls are required
- the control device has the characteristic that signals which transferred to one or more of the control devices, forwarded to the others and a reliable determination of the expansion units to be addressed in each case is possible via the common computer capacity.
- the protection controls 34 are connected to one another by the cable 58, which in previous versions has only two wires and which is used for serial transmission of a code word and the expansion command. Only the one of the protection controls 34 / expansion unit is addressed whose stored code word is identical to the transmitted code word.
- the cable 58 is therefore a two-core cable which is laid in the form of a bus line from one shield control 34 to the next and via which intermediate shield controls 34 also connects the main control center 50 and the auxiliary center 51 to one another.
- a second two-wire cable 59 is laid in parallel.
- the cables 68, 59 are also referred to in this application as bus lines
- the principle of the casing of the cables in the individual shield controls 34 is shown in FIG. 3.
- Two protection controls 34.1 and 34.2 of a large number of protection controls are shown.
- the shield controls are connected to the main control center 50 and the auxiliary control center 51 via bus lines 58 and 59.
- the bus line 58 has the two chamfers 58.1 and 58.2; the bus line 59 has the two chamfers 59.1 and 59.2.
- All four phases of both bus lines are the input elements 52 of the protection controls 34.1. 34.2, ... created From the input elements, the incoming signals are processed in the shield controls. H. first checked whether the codeword sent corresponds to the stored codeword and assigned to this respective label control. If the transmitted signals are control signals, the corresponding processing and forwarding then takes place to the corresponding functional elements of the shield, which have been described above.
- a chamfer 58.2 or 59.2 of each of the bus lines is then fed to a switching element 53.
- the corresponding chamfers leave the switching element 53 via the output and are then fed to the corresponding section enf 53 of the adjacent shield control 34.2.
- both bevels 58.2 and 59.2 can be separated synchronously or individually.
- the other chamfer 58.1 or 59.1 of the bus lines 58 or 59 are then fed to an amplifier element 54.
- the corresponding chamfers are fed from the output of the amplification element to the amplification element of the adjacent shield control 34.2 ....
- Each shield control 34.1, 34.2 ". then has a further “right” input element 52, which receives and processes the signals which come from the right-hand side, ie the auxiliary center 51 or a shield firing 34.3 .... located further to the right.
- Adjacent shield controls 34.1, 34.2 are therefore again by two Cables, each of which has two chamfers, connected.
- the switch 53 with its two switching elements is normally closed, so that a transmission takes place. However, the bus lines are disconnected when faults occur. On the one hand, this can make troubleshooting easier.
- one of the control devices main center, auxiliary center, handheld device or face control Shield control
- the switching elements of the shield controls on the right or left are opened individually and one after the other and then a control signal is entered. Since the Korttrollslgna! is immediately acknowledged by the addressed shield controls, it can be determined which of the shield controls are beyond the faulty shield control.
- the separation can take place in order to isolate a faulty shield control and to separate it from the bus line or the bus lines. This means that the other shield controls can still be controlled and the fault can be rectified without the strut being shut down.
- the incoming digital signals are refreshed in the amplification element 54. This is done by determining in the amplification element whether the incoming signals exceed a certain predetermined threshold value. If this is the case, signals of greater strength, preferably of the original strength, are generated in the output, so that the transmission of the signals is ensured by all protection controls. This type of amplification is particularly useful since the control signals, measurement signals etc. are transmitted in digital form become.
- control command is transported via the free bus line 58 or 59 in each case.
- the control commands are described in FIG Way through the individual shield controls 34.1, 34.2 .... Only the shield control is addressed whose stored code word matches the code word which is added to the control signal.
- the receipt and / or the execution of the corresponding control command can be acknowledged by a feedback signal , since one of the two bus lines 58 and 59 is available for this purpose.
- the feedback can be given immediately and without a time delay, so that an immediate control is also possible on the input device, ie main control center 50, auxiliary center 51 or control device 37.
- valve control 40 (FIG. 1) Passed.
- the control magnet of the pilot valve 45 is activated and the respective main valve 44 of the force transmitter 30 is actuated.
- the signals from the pressure sensors, which are arranged on each of the force transmitters and or valves for control and monitoring, can now also be transmitted back via the bus lines.
