2. Description of the Related Art Conventionally, unmanned wireless relay station power equipment is monitored only by transferring the ground of an alarm indicating an abnormality of the equipment to a monitoring table. There was a danger of a serious failure because it was not possible to confirm the status change other than going to the place where the abnormality occurred. In addition, the current power equipment information collection device only supports wired transmission lines,
A large amount of time may be required for a wired transmission line facility for enabling information transmission.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and collects more detailed information on the power equipment of a wireless relay station and establishes a wireless line in an area where it is difficult to install a wired transmission line. The power information of the wireless relay station that can be used as an alternative to the wired transmission path by using as a transmission path and allowing the supervisor to arbitrarily select multiple monitored wireless relay stations. The purpose is to provide a monitoring method.

[0004]

In order to solve the above problems, the present invention comprises a plurality of wireless relay stations and a monitoring center, and the wireless relay station has means for collecting power facility information and the collecting means. Means for wirelessly transmitting the selected information by an instruction signal from the monitoring center, and means for wirelessly transmitting the signals to the wireless relay station by selecting the plurality of wireless relay stations in the monitoring center. It is characterized by comprising means for receiving the information transmitted from the station, means for displaying the information and means for storing and accumulating, collecting more detailed information of the wireless relay power facility, In areas where it is difficult to install wired transmission lines, wireless lines can be used as transmission lines, and a supervisor can select multiple monitored wireless relay stations at any time to support all wireless relay stations. Alternative But also it made available to.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram of the configuration of a power information monitoring system of a wireless relay station.

That is, A wireless relay station 6, B wireless relay station 5,
It is composed of a plurality of wireless relay stations including a C wireless relay station 4 and an N wireless relay station 3 and a monitoring center 7.

At each of the wireless relay stations 3 to 6, a power facility 1 is installed.
A power information collecting device 9 for collecting information of 9 and a wireless transmitting / receiving device 2 for wirelessly transmitting the collected information by a station selection signal which is an instruction signal from the monitoring center 7.

In the monitoring center 7, a personal computer 10 selects a desired wireless relay station from the plurality of wireless relay stations 3 to 6 and a station selection signal of the desired wireless relay station is selected via a protocol converter 8. To the wireless transmission / reception device 2 that receives the information transmitted from the wireless relay station, and displays the information received by the wireless transmission / reception device 2 via the protocol converter 8 and stores and stores the information. And a personal computer 10.

From the monitoring center 7 to the monitored wireless relay station 6-
Up to N wireless relay stations 3 (up to 10 wireless relay stations)
Select a wireless relay station, collect analog detailed information of power equipment (maximum 20 items of information), digitize the collected analog detailed information of power equipment, and transmit it to the monitoring center 7 via the digital wireless line 1. 7 is displayed on the screen of the personal computer 10 and data is accumulated.

FIG. 2 is an explanatory view of the concrete configuration of FIG.
That is, the power information collecting device 9 includes the transducer 11,
It comprises a station selection interface 13, a power supply unit 14, a microprocessor 15, a ROM 16, a RAM 17, and an A / D converter 18. The transducer 11 converts the analog data of the information point of the power equipment 9 from 0 volt to +
Convert to 5 volts. The A / D conversion circuit 18 converts the data collected by the transducer 11 from analog to digital. The microprocessor 15 is a circuit that collects, rearranges, and sends out the digitized signals. The station selection interface 13 uses the microprocessor 15 only when its own station is selected by the station selection signal from the monitoring center 7.
Is a switch circuit that sends out the signal in (1) to the wireless transmission / reception device 2. Further, the power information collection device 9 is insulated from the wireless transmission / reception device 2 by interposing a photo coupler in the switch circuit of the station selection interface 13, thereby protecting the active wireless line. A wireless control device 12 controls the wireless transmission / reception device 2.

[0012]

As described above, according to the present invention, since it is possible to support without a wired transmission line, it can be introduced as a power equipment monitoring device for all wireless relay stations.
Further, by collecting and monitoring various data of the power equipment of the wireless relay station, it is possible to confirm in real time the voltage and current of various power equipment, the operating state of the emergency generator and the discharge state of the storage battery equipment.

From such characteristics, remote areas, heavy snow areas,
If there is an abnormal condition such as a failure in the Yamagami wireless relay station power facility without patrol roads, the supervisor monitoring multiple wireless relay stations can accurately check the status, eliminating unnecessary dispatch and improving safety. The efficiency of maintenance and inspection can be improved.
