A method for controlling a remote switch off of an undesired warning on a level crossing light signaling device and a remote control system for performing this method

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling the remote switching off of an undesired warning on electrically controlled level crossing safety devices with the transmission of information and commands between the level crossing device and the control station.

The invention also relates to a remote control system for this method of controlling the remote switching off of an undesired warning on a level crossing light signaling device.

BACKGROUND OF THE INVENTION

Nowadays, which is characterized by ever-increasing intensity of road traffic, undesirable warning on level crossing safety devices is becoming a burning problem. The occurrence of an undesired warning results from the functional nature of the level crossing safety devices, where a possible failure must mean a transition to a less permissive, more serious condition, an undesired warning. This means that some faults are signaled to the driver by the driver regardless of the presence of the railway vehicle in the control sections of the level crossing safety light equipment. However, the warning shall not last longer than necessary to ensure the safety of the crossing. The warning shall be limited to the time required for a railway vehicle to pass, a so-called critical period. Further duration of the alert is undesirable. The consequence of an undesired warning is a distrust of drivers in the function of the level crossing safety light equipment and failure to respect the level crossing signaling.

Standard tools used to interrupt or terminate an undesired warning are commands for emergency opening of level crossing safety devices, for stopping the level crossing and for emergency stopping of level crossing safety devices from operation. The functions of the individual commands are described in ČSN 34 2650. These commands, as well as information about the warning, are available to the traffic employee who monitors the function of the level crossing light signaling devices in the traffic station, which is immediately adjacent to the section of the railway track with crossing. Technically, information on the alert and the commands to terminate it is provided to the traffic employee by means of the controls and controls of the level crossing light signaling devices. The transmission of this information and these commands between the level crossing light signaling device and the transport is realized by a fixed line.

The situation is further complicated by the decreasing intensity of railway transport on some regional lines, where, for economic reasons, the services of transport employees are excluded and the railway operation is stopped in part or on the whole line. In such cases, precisely to address a possible undesired warning on the level crossing light signaling devices, the alert information is transmitted to the remote occupied conveyors. The transmission is also carried out over a fixed line. The commands for ending an unwanted alert are virtually not set up at all.

In the event of an undesired warning, the traffic employee advises the maintenance of the level crossing safety devices which turn off the device on site. Thus, an unwanted alert can take tens of minutes to hours.

The current technical solution of the unwanted alert is therefore imperfect, inefficient, operationally ineffective and expensive. The output information is transferred to a computer, printer and / or pager. Receiving information is announced by an acoustic signal.

WO 97/30879 discloses a remote monitoring system for monitoring outdoor devices. The system has one or more receivers for monitoring outdoor devices and transmitting multi-word messages. The transmitter is capable of communicating with multiple receivers and provides remote communication with the control station. The output information is transferred to a computer, printer and / or pager. Receiving information is announced by an acoustic signal.

The system is intended only for monitoring the monitored outdoor object. However, it is not intended to send commands from the control station to outdoor objects.

US 2004/182970 discloses remote monitoring of objects on a railway track. The system includes circuits for generating outdoor object status information, the information being provided to multiple users, such as a first communication line transmitting information from an outdoor device to a rail locomotive and a second communication line transmitting information from a rail locomotive to a location remote from the outdoor device. The second communication line can use existing locomotive diagnostic communications to the data center from which the information can be transmitted to the Internet from the locomotive.

The system is intended only for outdoor monitoring and is not intended for sending commands from the control center. Both of these inventions thus solve one-way communication.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to inform an employee intended to monitor the condition of the level crossing safety signaling devices of an undesired warning and to enable it to be switched off in a timely manner without the use of a fixed line.

The object of the present invention is to provide a remote control of the unwanted warning by means of a two-way wireless communication between the crossing light signaling device and a fixed and / or movable location intended for remote control of the unwanted warning. monitoring of level crossing safety signaling equipment. The surveillance server is a fixed place for monitoring the status of level crossing light signaling devices. A mobile radio terminal is a moving point for monitoring the status of level crossing light signaling devices.

The main advantage of this method according to the invention is a complex solution to the problem of undesired warning of level crossing safety devices without the use of a fixed line between the level crossing safety device and the place to be monitored. The method of the present invention provides transmission of the unwanted alert information, an indication of displaying the unwanted alert information, issuing an unwanted alert termination command, and processing an unwanted alert termination command at the level crossing safety light device.

Two-way wireless communication allows monitoring of an unlimited number of level crossing safety devices that are independent of their control and control parts. This communication shall not be limited by the distance between the level crossing safety-lighting device and the point of observation.

A fixed site for monitoring the status of level crossing light signaling equipment is a surveillance server that can be located at the dispatching maintenance center or any railway transport.

A mobile radio terminal is used as a movable point for monitoring the status of level crossing light signaling equipment, which is used in cases of temporary or permanent absence of fixed occupied stations.

-2GB 299538 B6

Advantageously, the wireless remote control of the unwanted alert deactivation is performed such that the unwanted alert is monitored by the supervisor module, then the unwanted alert information is transmitted via the radio module. Subsequently, unwanted alert information is displayed. Then the command to deactivate the unwanted alert is sent to the supervisor module. The monitoring module activates the safe measurement of the critical alarm time and the critical alarm is turned off after the critical time has elapsed.

When using a level crossing command, the unwanted alert remote control method can be performed by monitoring the unwanted alert by the surveillance module and transmitting the unwanted alert information obtained via the radio module of the level crossing security light device to the surveillance server of these devices or the mobile radio terminal. This unwanted alert information shall be displayed on the surveillance server of the level crossing light alarm or on the mobile radio terminal. Then, a command to impose an override at the level crossing to turn off the unwanted alert is sent to the surveillance server of the level crossing light signaling devices or from the mobile radio terminal back to the monitoring module. The supervision module activates the safe measurement of the critical alarm time and after this critical time, the overrun command is transmitted via the interface circuits to the light alarm logic, thereby terminating the alarm.

The stop command is selected when the warning has been triggered by a failure of the automatic and regular manual operation of the level crossing safety light equipment. The command is reversible. This means that one command is used to set a level crossing and another command to cancel a level crossing.

When using the Emergency Disable command, the method of remote control of the unwanted alert disarming can be performed in the same manner as in the previous method, except that the override command is replaced by the Emergency Disable command.

The Emergency Disconnect command is intended to deactivate an undesired warning that has been triggered by a fault in the level crossing safety light logic. The command is irreversible. This means that the level crossing safety light device which has been switched off can only be restored by the maintenance worker from the crossing point.

The method of controlling the remote switch-off of the unwanted warning according to the present invention is realized by means of the remote control system according to the present invention, characterized in that the system consists of an interface circuit of a level crossing safety light device of any type and a safe timer. the outputs of the diagnostics module and the radio module of the level crossing safety light equipment, from the radio network and / or the network of the mobile phone operator and also from the surveillance server containing the computer and radio module of the level crossing safety light monitoring system; terminal.

The interface of the level crossing safety lighting device of any type ensures the adaptation of the electrical circuits of the level crossing safety lighting device to the circuits of the supervisory module. The Safe Timer is designed to safely measure the time interval. It is true that no timer failure can shorten the measured interval. Radio and mobile phone networks ensure the transmission of information via wireless transmission media. The radio networks are suitable for smaller distances between level crossing safety lighting equipment and the surveillance site. For a greater distance between the crossing safety light equipment and the surveillance point, it is preferable to use the mobile operator's network or a combination of both networks. A surveillance server is a computer equipped with special software to display unwanted alert information and to command commands to turn off an unwanted alert. The mobile radio terminal may be either an alphanumeric display radio station or a mobile phone.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows the network of the surveillance server of the level crossing light signaling device, designated by the abbreviation PZS in Figures 1 to 3, and the network of the mobile radio terminal of the level crossing signaling light device. The mobile radio terminal has an internal radio module (not shown).

Both networks consist of several layers, a layer of the level crossing security light equipment, over which there is a surveillance layer, above it a communication layer and the top layer is a user and a processing layer.

The level crossing safety light device layer may be formed from any type of such a device, eg AŽD 71, VÚD, PZZ-RE, PZZ-EA etc. type. The level crossing security devices may be arbitrarily spaced from one another. The level crossing safety light layer is further formed from the interface circuitry and the safe timer unit, providing a safe measurement of the time interval, the function of which ensures that the measured time is not shortened.

Each individual level crossing security device and safe timer is connected in the supervisory layer by the respective logic unit. The logic unit detects the unwanted alert information via the input module, registers the unwanted alert information, and performs a con35 version of the information per message. The logic unit also provides conversion of the command message to a voltage signal through the output module. In this particular exemplary embodiment, a diagnostic module is also provided, which is a superstructure for diagnosing a level crossing safety light device.

The surveillance layer and the radio module of the level crossing safety light equipment constitute the surveillance module.

The supervisory layer logic unit is connected to the radio module of the communication layer level crossing security light equipment. This radio module provides transmission and reception of messages from the surveillance layer. It also provides transmission and reception of messages from the surveillance server of the level crossing security light equipment from the user and processing layer.

The surveillance server comprises the radio module of the surveillance server of the level crossing security light equipment and the user and processing layer, which is a computer and / or mobile radio ter50 minal.

The communication layer also consists of a special radio network or a mobile phone operator network or a combination of both networks. These networks are illustrated in dashed links between the radio module antennas in FIG.

-4GB 299538 B6

The user and processing layer may be either a computer of the surveillance server of the level crossing security light equipment or a mobile radio terminal.

The whole system of the level crossing safety light monitoring system is a device providing two-way wireless communication between the level crossing safety light device and a fixed place for monitoring the status of level crossing devices. These surveillance servers are flexibly placed in specified occupied traffic stations with or without control and indication elements of the monitored level crossing safety light equipment.

The surveillance server of the level crossing safety lighting equipment can also be located in the dispatching maintenance center. The operation of the surveillance server of the level crossing safety light equipment is independent of the control and control parts of the level crossing safety light equipment. It shall not be dependent on fixed lines and shall not be limited by the distance of the level crossing safety lighting equipment from the point of observation.

The Surveillance Surveillance Security Lighting System is a multifunctional system that is designed

a) for receiving, displaying and archiving messages from each individual monitored crossing security light device of unwanted alert, which is the basic function of this surveillance server,

(b) receive, display and archive messages from each individual level crossing safety monitoring device monitored and up to 15 additional diagnostic information characterizing the current status of the level crossing safety lighting facility, which is an enhanced function of this surveillance server; and

(c) to issue an undesired warning command on each individual level crossing safety device to be monitored.

The task of the surveillance server of the level crossing safety light equipment is therefore

- monitor the operation of any number of level crossing signaling devices 30 in one or more of the interstage sections, or all of these devices on the line, or all of them on all lines in the area, and

- in the event of an undesirable warning occurring on any of the level crossing safety devices monitored, switch off the warning.

The mobile radio terminal is a stand-alone device providing two-way wireless communication between the level crossing safety light device and a movable location for monitoring the status of the level crossing safety light device. The mobile radio terminal is used for complex solution of unwanted warning and monitoring of the level crossing safety light equipment in case of temporary or permanent absence of occupied stations.

Its function is the same as the above function of the surveillance server of the level crossing safety light equipment.

The system shown in Fig. 1 can utilize two basic ways of monitoring and disabling the unwanted alert, which are shown in the sequence diagrams in Figs. 2 and 3.

FIG. 2 is a sequence diagram for deactivating an undesired warning by commanding a level crossing at the crossing indicated by the abbreviation DK.NP in FIG.

The individual steps of the method are indicated by the reference numerals 50 in the time sequence in FIGS. 2 and 3.

The unwanted warning 1 is detected in the first step 2 by the supervisor module representing the supervisor layer and the radio module of the level crossing security device of Fig. 1.

-5GB 299538 B6

The unwanted alert information is sent to the surveillance server of the level crossing security light device in the second step 3 via the radio module of the surveillance server of these devices. This supervision server displays information about the undesired warning of the level crossing safety light device in the third step 4. The operator designated to monitor the level crossing safety light device enters a level crossing command in step 4. This command is transmitted from the level crossing safety light server to the supervisor module in step 6. The supervisor module registers this command in step 7, 7a and activates the critical time measurement with the safe timer in step 7. After the critical time has elapsed, the traffic idle command is passed to the crossing safety light logic. device in the eighth step 9. Accepting this command terminates the alert. After the crossing safety circuit circuits that caused the unwanted warning have been repaired, maintenance advises the crossing safety light operator to issue the level crossing suppression command in step 9. This command is again received by the crossing safety light supervisor to execute in the tenth step 12 of deregistering the introduction of a supervisory idle at the level crossing 11 by a wireless transmission 11 command to cancel the supervisory idle at the level crossing.

FIG. 3 is a sequence diagram for disabling an unwanted alert by the emergency force command indicated in FIG. 3 by the abbreviation NVC. The individual steps of the method are indicated in the sequence of FIG. 3 by numerals. The unwanted alert 1 is detected in the first step 2 by the supervisor module representing the supervisor layer and the radio module of the level crossing security light device of Fig. 1. The unwanted alert information is sent to the supervision server level crossing security light device in the second step 3 via the radio module to the monitoring server. The level crossing safety monitoring server displays information about the level crossing safety warning in the third step 4. The operator to monitor the level crossing safety lighting command passes the level crossing emergency stop in step 5. This command is transmitted from the level crossing safety monitoring server The supervisor module registers this command in step 6, 7a, and turns on the critical time measurement with the safe timer in step 7. After the critical time has elapsed, the emergency stop command is operating through the interface circuits. transmitted to the level crossing security logic in step eight 9. Accepting this command terminates the warning. After the crossing safety circuit circuits have been repaired, the crossing safety light maintenance personnel will reset the crossing safety light supervision module and thereby unregister the level crossing command in step 9.

In rare cases of lower intensity of railway traffic, where the service of transport staff is excluded for economic reasons, it is possible to use another alternative method of communication between surveillance servers and level crossing security devices according to the invention. In this case, for a limited time of day, the level crossing security devices are integrated into the network of a single surveillance server. After a given period of time, this server switches tracking cross-border security light equipment to the network of the second control surveillance server for the rest of the day. Thus, there is one additional command for possible reversible switching of the monitoring of the crossing safety lighting devices between the two networks.

Other ways of monitoring and commanding the level crossing safety light devices and control systems within the scope of the invention are possible.

Industrial applicability

The invention is suitable for railway light signaling devices for monitoring and disabling unwanted warnings.
