Abstract

PURPOSE:To suppress the interruption of a call at a minimum in the case of instantaneous power failure by providing a means, which resets a frequency and a press signal after recovery, in the controller of a base station equipment and executing battery backup only for the controller. CONSTITUTION:A controller 4 repeatedly executes the setting of a using frequency and the activation of transmission in a fixed cycle to a transmitter/receiver 5 with decided call allocation. After setting the using frequency and starting the transmission, data are exchanged by a data input/output 6. At such a time, when the instantaneous power failure is generated in an alternating current power supply input 2, the transmitter/receiver 5 is stopped and since power is supplied from a battery input 3 to a synthesizing circuit such as a diode or the like in the controller 4, however, the operation of periodically setting the using frequency and starting the transmission is continuously executed. Further, since the operation of periodically setting the using frequency and starting the transmission is repeatedly executed when alternating current power is supplied to the transmitter/receiver 5 after recovering the instantaneous power failure, the transmitter/receiver 5 is immediately returned to the original state. Thus, in the case of instantaneous power failure, the interruption of the call can be suppressed at a minimum.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a multi-channel access type base station device, and particularly to a base station device with improved countermeasures against instantaneous power outages.

[Conventional technology]

Fig. 3 shows a conventional base station device with complete power outage guarantee. , 7 is a press signal, and 8 is a control signal.

Next, the operation will be explained.

For the transceiver 5 for which the call assignment has been determined by the control section 4, the frequency to be used is set using the control signal 8, and then the press signal 7 is turned on to start the transmission of the transceiver 5. Thereafter, data is sent and received through the data input/output 6.

At this time, if a momentary power outage occurs in the AC power source 2, the operation of the controller 4 and transceiver 5 will stop, and it will be difficult to reset the frequency before the power outage in order to restart the transceiver 5 after the power is restored. Therefore, in the event of a power outage, power is supplied from the battery power 3 to the controller 4 and to the combination circuit such as the diode inside the transmitter/receiver [5] to prevent any abnormality from occurring in the telephone call operation.

[Problem to be solved by the invention]

The conventional completely power-out type base station device is configured as described above, and the transmitter/receiver 5 and controller 4 for several communication channels are backed up by battery, so depending on the level of the transmitting output of the transmitter/receiver 5, There was a problem with the need for large-capacity pantries.

This invention was made to solve the above-mentioned problems, and it is possible to minimize call interruptions in the event of a momentary power outage during a call, and to maintain the call operation without backing up the transmitter/receiver 5 with a battery. It is an object of the present invention to obtain a multi-channel access system base station device that can prevent abnormalities from occurring.

[Means for Solving the Problems] A multi-channel access base station device according to the present invention is one in which the controller is provided with means for resetting the frequency and press signal after power is restored, and only the controller is backed up by a battery. It is.

[Function] This invention is configured to reset the frequency and press signal, and only the controller is backed up by a battery, so it is possible to prevent call interruptions in the event of a momentary power outage without requiring a large capacity battery. can be minimized.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a simple instantaneous power outage guaranteed base station device according to an embodiment of the present invention, and in the figure, the same reference numerals as in FIG. 3 indicate the same parts.

Next, the operation will be explained.

In this embodiment, the controller 4 repeatedly sets the frequency to be used for the control signal 8 and activates the transmission of the transmitter/receiver 5 by turning on the press signal 7 at regular intervals according to the program for the transmitter/receiver 5 to which the call assignment has been determined. I will do it. After setting the frequency to be used and starting transmission, data is sent and received using the data output 6.

At this time, if a momentary power outage occurs in the AC power supply 2, the transmitter/receiver 5 will stop, but power will be supplied from the battery power 3 to the composite circuit such as the diode inside the controller 4.
The operations of setting the frequency used by the suspension jiJl and starting transmission are performed continuously. When AC power is supplied to the transceiver 5 after the instantaneous power outage is restored, the transceiver 5 is immediately returned to its original state because the frequency to be used and the transmission start-up are repeated at regular intervals.

As described above, according to this embodiment, since the setting of the frequency to be used and the activation of transmission are performed repeatedly at regular intervals, the transmitter/receiver 5 immediately returns to its original state without setting and activation again. Even if the transmitter/receiver +II5 is not backed up with a battery in case of a momentary power outage, there will be no abnormalities in call operation.

In the above embodiment, the transmitter/receiver 5 is programmed to repeatedly set the frequency to be used and start transmitting at regular intervals, so that it can immediately return to its original state after the power is restored. As shown in FIG. 2, a configuration may be adopted in which a momentary power failure recovery detection circuit is provided and the output of this circuit is used as a trigger to reset the transmitter/receiver, and the same effect as in the above embodiment can be obtained.

[Effects of the Invention] As described above, according to the present invention, the controller of the base station device is provided with a means for resetting the frequency and press signal after the power is restored, and only the controller is configured to have a battery bank-up. As a result, call interruptions during momentary power outages can be minimized without the need for large-capacity pantries.
This has the effect of not causing abnormalities in call operations.
