Abstract

PURPOSE:To ensure the system operation by a simple device operation by allowing an answer-back control section to send automatically a signal for supervising a slave station without operation of a supervisory control section after the end of a broadcast. CONSTITUTION:When the transmission to an outdoor slave station 8 is finished, a start signal used to send a supervisory signal to a supervisory control section 3 is sent from an answer-back control section 10. The supervisory signal in this case is received by a slave station 8 via a radio transmitter-receiver 7. Then the state of the slave station 8 is returned to the transmitter-receiver 7 as data, which are printed out by a communication recording equipment 5. Since the signal of supervising the slave station is sent automatically from the answer-back control section without operation of the supervisory control section after the end of broadcast in this way, the operation of equipment is simplified and the state of the slave station is supervised for every broadcast and the system operation is ensured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slave station monitor and control device for a master station facility used in a municipal disaster prevention wireless fixed system.

[0002]

2. Description of the Related Art FIG. 2 shows an example of the configuration of a municipal disaster prevention wireless fixed system which has been conventionally used. In the figure, 1 is a selective calling unit, 2 is a voice adjusting unit, 3 is a supervisory control unit, 4 is an automatic broadcasting device, 5 is a communication recording device, 6 is a switching unit, and 7 is a wireless transmission / reception device which constitutes the master station equipment. , 8 outdoor slave stations are terminal station equipment, and 9 indicates a loudspeaker speaker. The operation related to the present invention is as follows. The radio waves emitted from the radio transmitter / receiver of the master station equipment are received by the outdoor slave station 8 and amplified by the speaker 9. By operating the monitor control unit 3 to confirm the operating state of the outdoor slave station after the broadcast, the monitor signal is received by the outdoor slave station 8 via the selective calling unit 1 and the wireless transmission / reception device 7. The state of the outdoor slave station at that time is returned as data to the wireless transmission / reception device 7 as an answerback.

[0003]

However, in the above-mentioned conventional technique, since the manual operation is performed, the complexity and the omission of the operation occur. In addition, there is a drawback that broadcasting from an automatic broadcasting device, which is a system that allows unmanned broadcasting, cannot be supported. The present invention aims at automating the answerback of the state of an outdoor slave station in order to solve these drawbacks.

[0004]

According to the present invention, an answer back control unit is provided in the structure of FIG. 2 showing a conventional master station device, and a control signal is automatically transmitted from the answer back control unit at the end of broadcasting. It is characterized by being configured with a device.

[0005]

According to this configuration, the slave station monitoring signal is automatically sent from the answerback control section without operating the monitoring control section after the broadcast.

[0006]

1 is a block diagram showing an embodiment of an answer back automation system according to the present invention, and the same parts as those in FIG. 2 are designated by the same reference numerals. An answer back control unit 10 is provided. The operation of the answerback thus configured is as follows. When the broadcast to the outdoor child station 8 is completed, the answerback control unit 10 sends a start signal for sending a monitoring signal to the monitoring control unit 3. The monitoring signal at this time is received by the outdoor child station 8 via the wireless transmission / reception device 7. Thereafter, the state of the outdoor slave station is returned as data to the wireless transmission / reception device 7 and printed out by the communication recording device 5.

[0007]

According to the present invention, since the answer back can be automated, the operation of the device can be simplified and the state of the slave station can be monitored for each broadcast, so that highly reliable system operation can be performed.
