Description

  The present invention relates to a remote monitoring / control of a communication system, and more particularly to a mobile radio system suitable for monitoring a failure of a communication device in a plurality of base stations.

  There is a mobile radio system that constitutes dedicated mobile communication as a communication system that is applied to public works such as electric power and gas and serves as work support. The configuration of a conventional mobile radio system will be described with reference to the block diagram of FIG.

  Communication between the centralized control apparatus 1 that performs line control of a wireless connection method (example: SCPC method; Single Channel Per Carrier; frequency division transmission method compliant with ARIB STD-T61 standard) and a mobile station A command console 2 for selecting a base station radio from a plurality of base station radios 3 to be performed and a plurality of base station radios 3 and performing a call operation at a base station (business office, etc.) Thus, a base station is configured, and a plurality of mobile radio devices 4 which are mobile stations such as an in-vehicle radio device and a portable radio device are added to the base station to form a base zone.

  Further, the entire conventional mobile radio system is configured by a plurality of base zones.

  The one base zone is constituted by, for example, equipment provided in each sales office. The scale is usually one centralized control device 1, multiple command consoles 2, multiple base station radios 3, and multiple mobile radios 4. It depends on the scale.

  A plurality of base zones are individually operated as respective mobile radio systems.

  As a part of the operation, the command console 2 can monitor the operation state and failure contents of the base station radio 3 and the central control device 1 through the central control device 1.

  Therefore, when a failure occurs in the centralized control device 1 or the base station radio 3, or when a communication failure such as communication disconnection between the centralized control device 1 and the base station radio 3 occurs, the centralized control device 1 Failure information is sent to the command console 2, the failure information is displayed on the display section of the command console 2, and an operator in charge of operating the command console 2 recognizes a failure in the communication system. It is possible to issue a maintenance command such as changing 3 to another base station radio 3.

  As described above, since each of the plurality of base zones has individually dealt with the failure of the equipment for each base zone, it is uneconomical such as the number of equipment supplements increases as a whole mobile radio system. In addition, there is a time difference in the general business communication that requires an immediate command because other communication means are used, and the action start timing may be incomplete.

In a wireless communication system comprising a plurality of base station devices (base station wireless devices), a line control device (centralized control device) connected to them, and a plurality of terminal devices (mobile wireless devices), the communication connection time is reduced. I have a suggestion. (For example, see Patent Document 1)
JP 2006-87084 A (FIG. 1)

  In the prior art described above, since the mobile radio system was operated for each sales office in units of base zones, an administrator who supervises the entire mobile radio system having a plurality of base zones has to There is a problem that the operating state cannot be monitored in real time. In addition, when a failure occurs in a device, the failure information in real time can be obtained only at the command desk of the sales office where the failure occurs. There is a problem in that it is necessary to make an inquiry to an operator arranged at each place or wait for a report from the operator, resulting in a decrease in work efficiency.

  An object of the present invention is to solve the above-mentioned problems of the prior art, and an administrator who supervises the entire mobile radio system monitors in real time the operation state and the content of failure of each office device and issues a command by telephone To provide a system.

In order to achieve this object, a mobile radio system of the present invention includes a centralized control device that performs line control, at least one base station radio that performs radio communication with a predetermined mobile station, and at least one command that performs a call operation. A mobile radio system having a base station with a table,
The mobile radio system has an integrated command console for managing a system connected to an arbitrary base station selected from the base stations, and the arbitrary base station having the integrated command console is A centralized control device that is connected to a centralized control device of a station, is connected to each centralized control device of a plurality of base stations other than the base station by wireless or network, and performs integrated line control by integrating the centralized control devices. A control device connected to the first control device, connected to the second control device, and a second control device for monitoring and controlling the state of the equipment or fault monitoring in each base station, Display or operation means for selecting a device in each base station and displaying status or fault monitoring, and a call with the base station or mobile station connected to the first control device and controlled to be selected or called Call means to perform Equipped with a,
With the integrated command console, the telephone call and the state or fault monitoring can be integrated and managed in an integrated manner.

  According to the present invention, it becomes possible to comprehensively monitor the operation state and failure information of devices constituting a dedicated mobile radio system, thereby achieving efficient management of the entire system.

  Therefore, as a whole mobile radio system, the number of equipment spare parts to be prepared is reduced, there is no uneconomical aspect, and synchronic business communication requiring immediate command is ensured at the same time. It is extremely unlikely that the timing of starting actions will be incomplete.

  As an embodiment of the present invention, a block diagram of a mobile radio system is shown in FIG.

  Wireless communication between the centralized control device 201 that performs wireless connection system control and a predetermined mobile station is possible. If necessary, a plurality of base station radios 203, and a plurality of base station radios, an arbitrary base station radio A base station is constituted by a plurality of command consoles 202, if necessary, for selecting a machine and performing a call operation at the base station.

  Furthermore, this base station and a plurality of mobile radio devices 204 which are mobile stations such as in-vehicle radio devices and portable radio devices are provided, thereby constituting one base zone.

  Furthermore, a plurality of base zones are arranged in an arbitrary communication area, and the entire mobile radio system is configured.

  A central base zone 100 that controls the entire system is defined from a plurality of base zones, and the central base zone 100 includes a centralized control device 101 and, if necessary, a plurality of command tables as in the base zone 200. 102 and, if necessary, a plurality of base station radios 103 and a plurality of mobile radios 104 are provided.

  The one base zone 200 is constituted by, for example, equipment provided in each sales office.

  The number of devices provided is usually one centralized control unit 201, a plurality of command consoles 202, a plurality of base station radios 203, and a plurality of mobile radios 204. It is determined by the area size.

  In the case where a plurality of base station radios 203 are provided, the base station radio 203 is provided not only in the base station but also in a place away from the base station via a wired or network line in order to expand the base station zone. Good.

  The base zone 200 has a device configuration provided in a general sales office. On the other hand, the general base zone 100 is configured by a device provided in a sales office serving as a base. In addition to the same configuration as the above, the following equipment is provided.

  The mobile radio system of the present invention is provided with an integrated command console 110 composed of devices according to the following description as a base station facility in the integrated base zone 100.

  A base station facility in the integrated base zone 100 is connected to the centralized control device 101 by wire, connected to the centralized control device 201 in a general base station by radio or network, and a control box 111 (the first control box) that performs integrated line control of these lines. 1 control device), the control personal computer 113 (second control device) connected to the control BOX 111 for controlling the operation of the state of each base station device and fault monitoring, and the control personal computer 113. A touch panel 112 for selecting and operating a base station (sales office) and displaying the status of equipment / fault monitoring; a handset 114 connected to the control BOX 111 for making a call with a base station or a mobile station; 114, a headset 115 with a microphone that can make a hands-free call, and a handset 1 It is connected to the 4, a foot press SW116 with press-to-talk function of the transmission mode base station radios selected.

  In this manner, the integrated command console 110 has a function of selecting an arbitrary sales office from a plurality of sales offices in addition to the function of the general sales office command console, that is, selecting one or more base station radios. Business communication with a desired mobile radio can be performed.

  Note that the integrated command console 110 may be configured in a plurality according to the scale to be controlled.

  Next, an example in which a failure has occurred in the base station radio 203 will be described as an example of the operation of the entire mobile radio system having the above configuration.

  As a result of self-diagnosis of the state of the device inside the base station radio 203, the status and fault information are transferred to the centralized control device 201, and further, the base station radio 203 and the centralized control device 201 The device status is transferred to the command console 202 that can be monitored.

  Simultaneously with this transfer, the device status and failure information are transmitted toward a predetermined integrated command console 110 of the control base zone 100 via the network line.

  The transmission between the central control device of each base station and the control BOX 111 may be performed by allocating a radio channel of a base station radio included in each base station and transmitting information via the radio line instead of the network line.

  The command console 202 of the base station in which the failure has occurred displays an alarm when the failure information is received. Therefore, the operator of the command console 202 of the base station can monitor the failure status.

  The control BOX 111 provided in the integrated command console 110 receives device status and failure information from all base stations, and transfers device status and failure information data to the control personal computer 113. The failure information data is processed and converted into a format that can be monitored by the operator, such as a list display, although not shown, and the device status and failure information are displayed on the touch panel 112.

  Note that the control personal computer 113 has a function of storing monitoring data in a memory. The control personal computer 113 has a past device state and failure information as a database. It is also possible to obtain prediction data and display this information.

  In this way, the general sales office, that is, the administrator of the entire mobile radio system supported by the integrated command console 110, does not individually inquire about the operation / failure status of the device from the operator of the general sales office. As for the equipment status and failure information of the base station, the contents can be immediately received.

  Further, the general manager who manages the entire mobile radio system, from the result of receiving the immediate report and the display contents of the data processing result of the control personal computer 113, indicates the instructions for the base station in which the failure has occurred and all the base stations. A common instruction item is formulated, and a command for the formulation content is given by voice using the handset 114 or the headset 115, or command information is given immediately by data transmission using the touch panel 112.

  In addition, you may enable it to call between an integrated command desk and other command desks.

  As described above, the overall base zone 100 can centrally manage the response to the equipment states and equipment failures of all base stations, and can reduce the number of equipment accessories as the entire mobile radio system. As a result, it is possible to ensure the synchronicity of the general business communication that requires an immediate command, and to prevent incomplete timing of the action start.

  The present invention is applied to a wireless communication system used for mobile communication, and can be used as an example for dedicated mobile communication for public works.
