CS204652B1 - Connection for the central control of the train system for the industrial railways in the brown coal industry - Google Patents

Description

The invention relates to a wiring for the central control of an industrial rail system in a lignite mining industry whose track network comprises several surface mines, briquette plants and / or power plants using a remote data transmission device, a common track image and an operational computer.

Increasing mining output in opencast mines and refining facilities, as well as linking them to large enterprises in the lignite industry, requires a central control point for power transport by locomotives and wagons dedicated to coal and overburden to ensure both quality and quantity of production and avoid accidents .

Methods and connections are known in which the information is stored in divided tape and is visually inspected by means of screens and a scanning line method.

There are also known devices in which the driving data are registered by means of pulse wheel speed sensors, whereby the dies are cyclically interrogated from the control panel. ia and dismissed.

In addition, methods and connections are known in which information from multiple track memories is loaded via a query cycle to an operational computer that takes over control and management of trains.

Furthermore, a digital train announcement system is known whose six-digit message is divided so that the first place identifies the load, the second two places the origin, the third to the fifth places the train number and the sixth place the destination. gates. Once the destination has been reached, the characteristic data is changed so that now the place of origin is the current destination and the place of destination the current origin, making it clear that the train is moving back to the line gate.

A method is also known in which, in order to control train traffic, information is transmitted from vehicles by means of a 4 meter band radio to the train control station. In this case, the control station can reach each vehicle by selective call, so that only the selected information is transmitted. The operational status resulting from the information is then displayed on the signal board at the train control point.

This method has the disadvantage that it does not ensure a continuous flow of information, so that an immediate operational state is never shown on the signal board. In addition, the physical burden on control staff in relation to the statements made is very disproportionate,

All known methods of connection and equipment have the common drawback that, for the industrial tracks of large enterprises in the lignite mining industry, in which there is a branched track network and where both their own trains arrive and depart,

94652, on the other hand, trains from other large enterprises, where, in addition, there are different types of trains and loads, are not appropriate because they have too little information and the technical and economic costs are disproportionately high.

The purpose of the invention is to overcome these shortcomings and to achieve cost-effective central control of the train systems of the industrial railways of large enterprises in the lignite mining industry at an acceptable technical-economic cost.

SUMMARY OF THE INVENTION It is an object of the invention to provide an arrangement whereby at a relatively low technical cost, all trains present in a train system comprising several opencast mines, briquetting plants and / or power stations can be captured by visual information on a common track image of the central control point. it is still possible to identify the immediate distribution of trains and to increase the rózisah of information by ensuring at all times a statement on the number, type, cargo, destination, origin, location and overrun of all trains.

According to the invention, this object is achieved by providing the remote data receivers internally with a connection to the printout, an adapter and, via a switching amplifier, galvanically isolated to a digital DSP with a program interruption device and a DSP with the device. to interrupt the program is connected to the operating computer. A digital dynamic operational output unit and a digital static operational output unit are connected downstream of the operational computer to connect the operational computer to the common en-route image, followed by the signal shaping circuit. To change the information on the track image indicating fields, a common information circuit and a selective dynamic excitation and lubrication line are provided behind each signal shaping circuit. For visual indication of the overall information, a central indicating device is provided, which is assigned a train number selector, followed by a gate circuit and a selector button with a monostable multivibrator downstream thereof, the gate outputs being connected galvanically separately to the digital dynamic operational input unit. to interrupt the program.

To send a repeater signal after a negative test, a switching amplifier is connected downstream of the shaping central indicating device and is connected to a remote data receiver.

The advantage of the circuitry according to the invention is that, with relatively, low technical and economic costs, optimum control of the industrial rail train systems is achieved even under special conditions of train operation in the lignite mining industry.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be illustrated by way of example with reference to the accompanying drawing.

In individual reporting areas, eg railway gates, remote data transmission devices or semi-automatic train number transmission devices are located for transmitting information. To receive this information, remote data receivers 1 are arranged at a central control point provided with a common track image. They store the short-term data transmitted and transmit it via the switching amplifiers 2 to a common downstream digital dynamic input input unit 3 with a program interruption device. To transmit information for the common track image indication field 4, a digital static operational output unit 8 is assigned to the operation computer 5.

Each display field 4 is assigned three digital display screens 7 with numeric data of zero to nine with a pre-decoding matrix 8 converting the decimal binary code to a code of one in ten. The selection of the allowable light bulb 11 and insertion into the static memory 9 is made by the operating computer 5 via the digital dynamic operational output unit 10 for each indication field 4. To test the allowable light bulbs 11 which are also controlled by the digital static output unit 6, a test portion is provided. In addition to the common track image, a central display device 13 is provided. This serves to indicate complete train information and to indicate that the permitted time has been exceeded. The central display device 13 is assigned train number selector switches 14, a control button 1S and gate circuits 16 and a monostable multivibrator 18. The gate circuit outputs 16, as well as the remote data receivers 1, are galvanically isolated to a digital dynamic input unit 3 with a device for interrupt the program. For example, when conveying information about · eight characters, the train number is numerically represented by the characters one and two, the train types are alphanumerically indicated by the characters three, the cargo is alphanumerically indicated by the four characters, the destination is numerically indicated by five and six. eight.

Upon entering the information into the remote data receiver 1, this information is character-related and hit-parallel. Each time the characters change, the interrupt signal of the digital dynamic operating input unit 3 with the program interruption device is energized and the information is taken over by the operating computer 5. The operating computer S performs the correctness test and transmits the information to the track image. In the negative decision, the operating computer S does not receive the information and a fault signal is sent to the remote data receiver 1.

In the affirmative decision, the operating computer 5 examines whether the train number information is already recorded on the track image; if so, then this information is cleared and new information is written according to the desired indication field 4. In this erasure and excitation process, the front face of the dynamic signal is cleared. Shortly thereafter, the stationary information is prepared time-delayed on the orbital header and immediately thereafter is written by the front steep face of the dynamic signal.

The operating computer 5 keeps the complete train information in memory for possible further processing for central indication.

To visually display the complete train information, the desired train number is preselected on the train number selector 14 and, with the control button 15, the gate circuits 16 are opened, the signal is activated by the digital dynamic input unit 3 and via the operating computer 5; causes 8 characters to be sent completely. All incoming information is registered in the operational computer 5 with the time of entry and when the permitted train time is exceeded, the operational computer 5 illuminates the authorized time light bulb 11 via the digital static operational output unit 16. At the same time, the cumulative summation of the exceeding of the allowed time starts in the production computer. This overrun is shown, after actuation of the train number selector 14 for the train in question, on three additional digital display screens 7 of the central display 13 arranged next to the eight character digits for overall information.
