2. Description of the Related Art A switching station constituting a public communication network and radio base stations and other stations of a mobile communication system are geographically dispersed and individually installed. These stations are installed at remote locations, at the top of a mountain or in other remote areas. In many cases, it is set to a different position. Therefore,
For these stations, by applying a remote monitoring and control system that monitors and controls from the maintenance center via a communication line, for example, it is possible to smoothly determine whether or not the operation is normal and vote on failure points smoothly. In addition, the reconfiguration of the system and the switching of the operation mode are promptly performed according to the operation or other demands.

In a small-zone mobile communication system, the number of wireless base stations to be installed increases as the diameter of the wireless zone becomes smaller. Often done. The remote monitoring control system described above is also used for comprehensively grasping the operation status of many such radio base stations and for efficiently operating the radio base stations based on the results of the grasp. .

FIG. 4 is a diagram showing a configuration example of a conventional remote monitoring control system. In the figure, the monitored station 60 is connected to the maintenance center 62 via the transmission path 61 ₁ to 61 ₄ provided in parallel.

[0005] In the monitored station 60, input and output of the monitoring device 63 ₁ is connected to one end of the transmission line 61 ₁ through the monitoring device 64 _1, the input and output of the monitored device 63 ₂ through the monitoring device 64 ₂ It is connected to one end of the transmission line 61 ₂ Te. Furthermore, one of the input and output of the monitoring device 63 ₃ is connected to one end of the transmission path 61 ₃ via the monitoring device _643, the other input of the monitoring device 63 ₃ is a transmission path through the monitoring device 64 ₄ It is connected to 61 ₄ at one end.

[0006] In the maintenance center 62, the transmission lines 61 _{1 to} 61
The other end of ₄ is connected to the corresponding communication port of the processing device 65, and the input / output port of the processing device 65 is connected to the input / output device 66.

[0007] In the remote monitoring and control system having such a configuration, the monitoring devices 64 ₁ and 64 ₂ each include the monitored device 6.
3 _1, 63 transmission path 61 ₁ for ₂ maintenance monitoring information, 6
Interfaces with 1 _2.

Namely, the maintenance monitoring information output separately from the monitored device 63 _1, 63 ₂ (e.g., indicating contact of the switch provided on the operation unit state, the operating status of the presence or absence of lighting of the lamp and station power hardware information) are respectively transmitted through the transmission path 61 _1, 61 ₂ to the maintenance center 62.

In the maintenance center 62, the processing device 65 receives such maintenance monitoring information, performs a predetermined process, and sends a result of the process (for example, a message or status display information) to the input / output device 66. Output.

Accordingly, personnel work involved in maintenance and operation of the monitoring station 60, the identification of the monitoring device 63 _1, 63 ₂ of the operation correctness determination and fault point based on the information output this way , And the work adapted to the results of such determination and identification can be performed promptly.

When any instruction is given via the input / output device 66 in accordance with such a task, the processing device 65 analyzes the content of the instruction, and displays a result of the analysis. Information (for example, monitored devices 63 ₁ , 63
_For the operation ( ₂ ), information for switching aspects or requesting intermittent control is generated. Furthermore, the processing device 65, such maintenance monitoring information transmission paths corresponding to the transmission destination (in this case, the transmission path 61 ₁ for simplicity.) Is sent to.

In the monitored station 60, the monitoring device 64 ₁ sequentially monitors the maintenance monitoring information received via the transmission line 61 ₁ and controls the operation of the monitored device 63 ₁ according to the content thereof. On the other hand, the monitored devices 63 _3, transmits and receives maintenance monitoring information via two routes adapted to the two different communication procedure. Therefore, these maintenance monitoring information is given to the monitoring device 64 _3, 64 ₄ corresponding individually to the communication procedure respectively above, further, the transmission path 61 _3,
61 ₄ through a given processing unit 65 of the maintenance center 62. Note that in this way the monitoring device 64 _3, 64 ₄ and the transmission path 61 _3, 61 ₄ processing apparatus maintenance monitoring information sent and received via the applying process, the monitoring device 63 _1, 6
3 processing same as because the to be performed on ₂ maintenance monitoring information related to, and a description thereof will be omitted.

However, in such a monitored station of the conventional configuration, each monitored device is connected to the maintenance center 62 via a separately provided monitoring device and transmission line. Furthermore, maintenance monitoring information is transmitted / received in parallel based on a communication procedure that differs for each monitored device, and maintenance monitoring information including a plurality of items (for example, the hardware information and the monitoring information of the station power supply of the corresponding station) is included. It monitored devices 63 ₃ for transmitting and receiving in parallel information was connected to the maintenance center 62 via the transmission path monitoring apparatus individually corresponding to these communication procedures and items.

In the maintenance center 62, the processing device 65
Are all monitored devices 63 ₁ installed in the monitored station 60.
To 63 along with maintenance monitoring information collectively transmitting and receiving according to ₄ were performed in a batch processing for these maintenance monitoring information.

Therefore, it has been difficult to adapt to the change or addition of the hardware configuration due to the collection of the monitored station 60 or to flexibly cope with the change of the software. Further, such measures are often hindered by the upper limit of the processing amount of the processing device 65 in particular, and work is complicated because load distribution or function distribution is not achieved.

An object of the present invention is to provide a monitoring device and a centralized monitoring device capable of reducing costs required for installation and operation, and capable of flexibly and smoothly responding to expansion and recovery required for the operation. I do.

Therefore, in the remote monitoring and control system to which the present invention is applied, the cost required for installation and operation is greatly reduced, and the monitored station, the monitored device, the items to be monitored and controlled, and the remote monitoring and control are performed. Flexible development and extensibility with respect to the change of the execution form of the work related to the control are secured.
