Abstract

PURPOSE:To eliminate the trouble for redialing and to facilitate an operation by enabling a user of a slave station to make a call without dialing when the data transmitted from a key station includes a telephone number. CONSTITUTION:When the message data includes the telephone number for which a control signal is added, the telephone number is displayed on a display part 25 by operating a calling operation part 27. Then a signal generation part 28 generates a push-button dialing signal and a push-button dialing signal tone is outputted through a speaker 24. Then the handset of a push-button telephone set is hooked off and the push-button dialing signal tone is inputted to the transmitter, thereby making a call similarly to the operation of the key pads of the push-button telephone set. Consequently, the trouble for redialing is eliminated and the operation is facilitated.

Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a radio paging system that is used for a local radio paging system, a voice alarm, local communication, etc., and allows a master station to call a slave station using radio waves.

[Conventional technology]

Conventionally, in this type of focal line calling system, a master station sends transmission data including message data to a slave station, and when the slave station receives the transmission data, it notifies the reception by voice etc. A device that displays a message corresponding to message data is provided.

[Problem to be solved by the invention]

In the above-mentioned conventional TLL, when it is necessary to make a call in response to a message, there is the trouble of having to confirm the telephone number of the other party before making the call. Further, even when a telephone number is displayed in a message, it is necessary to make a call while looking at the display, which is troublesome. The purpose of the present invention is to solve the above-mentioned problems, and when a telephone number is included in the data transmitted from the master station, the user of the slave station can make a call without dialing. The aim is to provide a wireless paging system that eliminates the hassle of making phone calls.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a master station consisting of a wireless transmitter and a slave station consisting of a wireless receiver, and the master station includes an input section for creating message data to be sent to the slave stations, and a slave station for generating message data for the slave station. The slave station includes a transmitting section that sends out transmission data including data as a focal line signal, and a slave station includes an audio output section that notifies that transmission data from the master station has been received, a storage section that stores message data, and a message output section. In a radio paging system equipped with a display unit that reads a message corresponding to the data from a storage unit and displays it, the message data created at the master station may include a telephone number with a control symbol added to the beginning as necessary. When a calling operation is performed at the slave station, the telephone number with a control symbol added thereto is read out from the storage section, and a push-button dial signal sound corresponding to the telephone number is output from the audio output section.

[Effect]

According to the above configuration, when the master station sends transmission data including the 14-phone number, the slave station can extract only the telephone number and output the push button dial signal sound corresponding to the telephone number. By setting the handset of a push-button telephone off-hook and inputting a push-button dial signal tone to the transmitter, the user of the slave station can make a call without performing any dialing operations. In other words, the hassle of dialing is saved and the operation becomes easier.

【Example】

As shown in FIG. 1, the master station 1 is a wireless transmitter, and the slave station 2 is a wireless receiver. An address is set in advance for the slave station 2, and the master station 1 identifies the slave station 2 by sending address data. #i station 1 is provided with an input section 11 for inputting address data and message data to slave station 2;
Transmission data TD consisting of address data AD and message data MS input from the input section (see Figure 2)
is transmitted as a wireless signal through the transmitter 12. The message data MS can include a telephone number DN, which is a numeric string of about 10 digits at most, if necessary. The telephone number DN is provided at the end of the message data MS, and the M symbol C8 is added to the beginning of the telephone number DN. The slave station 2 includes a receiving section 21 that receives and demodulates the wireless signal from the master station 1, and the address data of the transmission data output from the receiving section 21 matches the address set in the slave station 2. The determination unit 22 determines whether or not to do so. If the addresses match, a notification sound is output from the speaker 24, which is an audio output section, through the notification section 23. At the same time, a message corresponding to the message data is displayed on the display section 25, and at the same time, the message data is stored in the storage section 26. is stored. When the message data includes a telephone number with a control symbol added, when the call operation section 27 is operated, the telephone number is displayed on the display section 25, and the signal generation section 28 generates a push button dial signal. , a push button dial signal tone is output through the speaker 24. The pushbutton signal tone is a high group (1
209-1633Hz) and low group (697-941Hz)
If the handset of the push-button telephone is placed off-hook and the push-button dialing signal tone is input to the handset, the user can make a call in the same way as when operating the keypad of the push-button telephone. This is possible. The slave station 2 has an appearance as shown in FIG. 3, and the speaker 24, the display section 25, the operation handle of the call operation section 27, etc. are exposed on the surface of the case 20. In addition, slave station 2
A charging terminal 29 for a secondary battery that is a power source is also provided.

【Effect of the invention】

As described above, the present invention includes a master station consisting of a wireless transmitter and a slave station consisting of a wireless receiver, and the master station includes an input unit for creating message data to the slave station, and a transmission unit including the message data. The slave station includes a transmitter that transmits data as a wireless signal, and a voice output unit that notifies that it has received transmission data from the master station, a memory that stores message data, and a message that corresponds to the message data. In a radio paging system equipped with a display unit that reads out and displays a message from a storage unit, the message data created by the master station can include a telephone number with a control symbol added to the beginning as necessary, and When a call operation is performed, a telephone number with a control symbol added is read from the storage section, and a push-button dial signal tone corresponding to the telephone number is output from the audio output section. When transmitting transmitted data, the terminal station can extract only the telephone number and output the push-button dialing signal tone corresponding to the telephone number, so the handset of the push-button telephone can be placed in an off-footer state and connected to the transmitter. By inputting a push-button dial signal tone, users of the five slave stations can make calls without performing any dialing operations. As a result, the dialing effort is saved and the operation becomes easier.
