Abstract

PURPOSE:To attain definite management by a center side monitor transmitter and to save man-hour of the management by allowing the center side monitor transmitter to preserve management information of a remote side monitor transmitter and transferring the management information to the remote side monitor transmitter via a packet exchange network as required. CONSTITUTION:The management information of remote side monitor transmitters 3(1)-3(n) is stored in a storage section 5 of a center side monitor transmitter 1 by the control of a central processing section 6. When monitor information or the like from a monitored equipment 8(1) inputted from an input output section 11 (1) of the remote side monitor transmitter 3 (1) is desired to be changed, the central processing section 6 of the center side monitor transmitter 1 rewrites the management information of the remote side monitor transmitter 3(1) stored in the storage section 5 into a content desired to be changed. Then the management information 7 is transferred to the remote side monitor transmitter. 3(1). A central processing section 12 (1) receiving the management information 7 via a packet exchange network 2 and a communication control secticn 9(1) inputs the management information 7 to a storage section 10(1), in which the stored content is revised.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a monitoring transmission device for remotely monitoring the operating status of communication equipment.

[Conventional technology]

Conventionally, there have been the following types of monitoring transmission devices of this type.

The first monitoring transmission device is not provided with any parameters that define the operating conditions and functional conditions of the device.

The second monitoring transmission device is capable of changing the operating conditions of the device by setting the parameters, and the parameter setting means is semi-fixed by a switch or the like inside the device.

The third monitoring and transmitting device is of a type that transfers the parameters from the center side monitoring and transmitting device to the remote side monitoring and transmitting device by data transmission.

[Problem to be solved by the invention]

The conventional monitoring transmission device described above has the following drawbacks.

(b) The second monitoring transmission device can change the operating conditions of the device by setting parameters, but since this parameter is set locally on the remote monitoring and transmission device, when changing the parameters, maintenance personnel must go to the remote monitoring and transmission equipment and manually make changes. Therefore, the modification work requires time and effort, and errors are likely to occur in the parameter modification settings. Furthermore, when the parameter settings become defective, abnormality detection and parameter resetting must be performed locally and manually for each remote monitoring and transmission device, which requires extremely complicated work.

(b) The third monitoring and transmitting device lacked reliability because there was no recovery method in the event that parameters were lost or parameter settings were destroyed in the remote monitoring and transmitting device.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a supervisory transmission device in which the central supervisory transmission device centrally manages the remote supervisory transmission device and simplifies the management.

A storage unit for storing management information transmitted from the center-side monitoring transmission device, and a storage unit that stores management information transmitted from the center-side monitoring transmission device, and periodically checks whether or not there is a failure in the stored management information to detect failures. The present invention is characterized by comprising a central processing unit that occasionally issues the management information transfer request to the center-side monitoring transmission device.
