Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is an automatic system that has both a button dial function and a pulse dial function, automatically determines the line type, and dials a desired telephone number. This invention relates to a dialing device.

Conventional Structures and Problems Generally, when making a telephone call, the first step is to pick up the handset and dial the telephone number of the other party, but it is troublesome to dial frequently used numbers one by one.

Nowadays, automatic dialing devices that store a phone number in memory and automatically dial it with the touch of a button have become popular. However, there are two types of telephones: those with push dials and those with ordinary rotary dials (hereinafter referred to as pulse dials), and conventional automatic dialing devices are only of the pulse dial type. Even if it was possible to do both, it would have to be switched using a switch or the like.

Page 3 Purpose of the Invention The present invention solves the above-mentioned conventional problems, and automatically determines whether the line in use is a button dial type or a pulse dial type, and determines whether the line in use is a button dial type or a pulse dial type. The purpose of this invention is to provide an excellent automatic dialing device that can automatically dial according to the line.

Components of the Invention The present invention includes both a push-dial drive unit and a pulse dial drive unit. First, one of the dial drive units dials the last digit of a telephone number, and a dial enable signal (dial tone) is output from the exchange. ), the circuit is configured to detect whether the line is a push dial type line or a pulse dial type line, and drive each dial drive unit based on the above judgment result to perform dialing. It is.

Reference numeral 2 denotes a pulse dial driving means, which connects/disconnects the telephone line as many times as the number at predetermined intervals, in the same way as dialing with an ordinary rotary dial telephone. 3 is a dial tone detection means that detects a dial tone that sounds like "two" when the handset is raised when making a normal telephone call. Reference numeral 4 denotes a control means that reads a telephone number from the dial number storage means 5 in which the telephone number to be dialed is stored in advance, and if there is an output from the dial tone detection means 3, first only the first two digits of the telephone number are sent to the button. Dial with the dial drive means 1, then check the output of the dial tone detection means 3 again, and if there is no output, continue dialing with the button dial drive means 1, and if there is an output, dial the telephone number with the pulse dial drive means 2. It's programmed to dial back from the beginning.

7.8 is a resistor and capacitor for absorbing noise generated during dialing. 2a and 2b are relays for dialing in the pulse dial type, 2a is the contact part, and 2b
is the drive coil section. 1 is a push dial drive means for dialing with a push dial type; 3 is a push dial drive means for dialing;
It is a dial tone detection means designed so that an output appears when a dial tone frequency is input. 1
0 is a hybrid transformer used in ordinary telephones, the signal input from the terminal 6a16b is transmitted only to the dial tone detection means 3, and the signal output from the button dial drive means 1 is transmitted to the terminal 6a16b. It is something that can only be communicated to. 2C is a transistor that drives the dial relay coil 2b, 9 is a diode for preventing the transistor 2C from being destroyed by the back electromotive force of the relay coil 2b, and 2d is a base resistance of the transistor 2C. Reference numeral 12 denotes a switch for specifying the start of dialing, and when this is pressed, the microcontroller page computer 11 starts an automatic dialing operation according to a built-in program. The microcomputer 11 includes an input section 11a that inputs signals from the dial tone detection means 3 and the dial start switch 12, and an output section that outputs necessary signals to the transistor 2C that drives the dial relay 2b and the bush dial drive means l. 11d1 A storage section 11C that stores telephone numbers, and an arithmetic control section 11 that controls the input section 11a, output section 11d, and storage section 11c. b
It consists of

FIG. 3 is a flowchart showing the main parts of the operation of the microcomputer 11 of this embodiment.

The operation of this embodiment will be explained below.

The user first lifts up the telephone handset and presses the dial start switch 12. Then, in step 21, the microcomputer 11 selects the transistor 2.
A signal to turn on C is output, and dial relay 2b is turned on. In other words, contact 2a is closed. This allows terminal 5
The dial tone input from page 7 a and 6b is input to the dial tone detection means 3 through the contact 2a and the hybrid transformer 10. When a dial tone is detected in step 22, the microcomputer 11 controls the storage section 11c in step 23.
Calculating and controlling the phone number stored in advance]
, 1b.

As shown in step 24, only the first two digits of the read telephone number are output to the push-dial driving means 1 and dialed using a push-dial method. At this time, if the telephone line is a push-dial type, the line becomes silent, but if it is a pulse-dial type, a dial tone is inputted to the dial tone detection means 3 again through the terminals 6a, 6b, the contact 2a, and the hybrid transformer 10. Ru. Therefore step 2
5, if the telephone line is a bush dial type telephone line, the process proceeds to step 26, where dialing signals for the third and subsequent digits are outputted to the bush dial driving means 1, and dialing is continued. If it is a pulse dial type telephone line, the dial tone will be detected again, so the process will proceed to step 27, and the transistor 2c will be connected to the telephone number from the beginning of the telephone number at intervals of one. A signal for turning off and on is output from the output section lid, and dialing is performed using a pulse dial method.

In the above embodiment, only one number is automatically dialed, but even if there are multiple numbers, the memory unit 11. The system can be easily configured by simply registering a plurality of numbers in d and increasing the number of dial start switches 12 by the number of the numbers.

In the embodiment, only the first two digits of the telephone number are first output to the pushbutton dial drive means 1, and dialing is performed using the pushbutton dial method, but conversely, the number of times corresponding to the first two digits is Turn off transistor 2c at regular intervals,
The signal to turn on may be output from the output section 1d. However, in this case, if the dial tone detection means 3 subsequently detects a dial tone, the push-dial drive means outputs a push-dial signal from the beginning of the telephone number, and if no dial tone is detected, the push-dial drive means outputs a push-dial signal from the beginning of the telephone number. It goes without saying that the configuration must be made so that the transistor 2C is turned off and on at regular intervals the number of times that corresponds to the number after the digit.

Effects of the Invention The present invention can be used with either a push-dial telephone line or a pulse-dial telephone line and automatically determines which line it is. It has the advantage of being extremely easy to use, since there is no need to know anything about it, and there are no setting mistakes made by the person in charge of installation work. Furthermore, even if the line is switched from a pulse dial type to a bush dial type or vice versa, it can be used as is without any changes, which is extremely advantageous in practice.
