Abstract

PURPOSE:To obtain a using record and charging control through a telephone set by installing a self-station number setting device and memory part for storing provisionally the number of a called party on each telephone set. CONSTITUTION:When a call party presses a pushbutton of a dial 2, a key detection means 31 of a control part 3 detects which number of the dial is pressed with the aid of a key scan signal, and transmits its data to an arithmetic control part 40. It collates key digit discrimination data stored at a specific address of the memory part 38. When the dial is the 1st digit, said control part 40 outputs a pulse corresponding to a self-station number before it transmits the 1st digit dial signal. Then, the output of a dial pulse corresponding to the key data inputted to the 1st digit is read out to the arithmetic control part 40 from the key buffer of the memory part 38 where the 1st digit dial data is stored through a memory read/write means 39, and this pulse reading is executed in the same manner as outputting the self-station number. When the 1st digit dial output is completed, the operation is shifted to the output action of the next dial data. Where data exists in the key buffer, it is outputted: otherwise, the operation comes to an action for waiting a key input.

Next, the operation of the above embodiment will be explained. In FIG. 1, a calling operation will be described with telephone line connection terminals 1 (Ll, L2) connected to the main device via a PBX line or a button telephone device line.

When the handset section 19 housing the handset 5 and handset 6 is opened, the hook switch 12 interlocked with the handset section 19 is activated, and the telephone line connection terminal 1 (Ll, L2) is opened. The impedance of the communication circuit 4 and power supply circuit 9 is approximately 150Ω from the almost open state.
Go back and forth.

Therefore, the PBX or button telephone device determines that the subscriber's telephone has entered the calling state, and outputs a dial tone to the telephone line terminal 1 (Ll, L2). Similarly, the hook switch detection means 35 also detects that the hook switch 12 is in the operating state, and sends a signal to that effect to the arithmetic control unit 40, and the arithmetic control unit 40 recognizes that the hook switch 12 is in the on state. do. This action is the second
This is shown in step 50 of the foot switch detection process in the figure.

Next, when the calling party hears a dial tone through the communication circuit 4 and uses the receiver 6, it is determined that the calling party is ready to make a call, and the caller proceeds to dial the number of the called party in order to call the called party.

When the caller presses the dial 2, the key detection means 3 of the control unit 3
1 detects which dial number is pressed using a key scan signal and sends the data to the arithmetic control section 40. This flow is shown in key judgment input step 51 in FIG. In order to determine whether the input data is the first digit, the arithmetic control unit 40 compares the key digit determination data stored at a specific address in the memory unit 38 and determines whether the input data is the first digit. , dial data storage processing step 53 in FIG.
The process moves on to subsequent steps, and if it is the second digit or later, the process from step 57 onward, which is a dial storage process, is performed. The determination flow for the first digit of the key manual power here is shown in key manual power first digit determination processing step 52 in FIG.

If the dial is in the first digit, the procedure is to output a pulse corresponding to the own number before transmitting the first digit dial signal. Next, this operation will be explained.

After determining the first digit, the key data sent from the key detection means 31 is stored in the memory section 38 in the arithmetic control section 40.
Memo IJ - reading/writing means 39
is operated and stored in the keeper sofa part at the specified address. This flow is shown in key reading data storage processing step 53 in FIG. Next, the process moves on to the operation of reading the own station number setter 14 to determine what number the own station number is set to.

Since the arithmetic control unit 40 shown here is capable of 4-bit parallel input processing, the upper level input is processed at once.

Since lower numbers cannot be read, a scan output signal is first sent to the own number reading means 33 in order to detect what number the lower number is set to, and this is sent to the own number reading means 330 input port. Since it is input as a BCD signal corresponding to the set number,
The lower number can be determined and this data is sent to the arithmetic control section 40.

Here, like the key data, it is temporarily stored at a designated address in the memory section 38.

Furthermore, the upper setting number is read in the same way as the lower setting number, and this process corresponds to step 54 of reading the own station number in FIG. Note that the diode 15 is used to prevent reading errors when a key is pressed twice.

The arithmetic control unit 40 outputs this own station number in step 5.
Move on to 5. First, the DSIJ relay 20 is operated to protect the communication circuit 4 from generating pulse clicks. This is done by operating the relay control means 36 from the arithmetic control section 40,
Furthermore, the procedure is to operate the DSIJ relay 20 via the relay drive unit 37.

The spark killer 18 serves to prevent counter electromotive force generated in the coil of the DS relay 20.

After operating the DS'J Ray 20, send 20 pp of impulses corresponding to the higher number of your own station number read earlier.
s or 10 pps, and this output is sent from the arithmetic control section 40 to the relay control means 36. This is possible by operating the relay drive unit 37 and turning the dial relay 13 on and off. A diode 18 provided in the dial relay 13 is used to prevent reverse activation.

Next, the output of the lower number of the own station number is read by the arithmetic control unit 40 from the specified address of the memory unit 38 through the memory read/write means 39, and this is processed in the same manner as the output of any higher number. Output. This process corresponds to the own station number output process step 55 in FIG. DS here
The relay 20 is controlled by the arithmetic control unit 40 so as to operate only while outputting impulses.

Next, the process moves on to outputting a dial pulse corresponding to the key data input in the first digit. The first digit dial data is read from the key buffer of the memory section 38 through the memory read/write means 39 to the arithmetic control section 40, and is sent to the DS relay 20 in the same way as when outputting the own number. The dial relay 13 is controlled to output a pulse. This process corresponds to the first digit dial output process step 56 in FIG. The data is read by the interrupt operation of the arithmetic control section 40, and the memory reading/writing means 39 and the memory section 38 are operated to perform the process of storing it in the keypad.

When the first digit dial output is completed, the operation moves on to outputting the next dial data. This is an operation in which if there is data in the key buffer, this data is output, and if there is no data in the key buffer, it waits for the next key input. When the first digit dial output is completed, the state returns to the hook switch detection processing step 50 again, and the H/Dose note section 19
If the keypad is hooked up by the caller, then the process moves to key human power detection processing 51, and if no key is pressed, the process moves to step 61 for determining whether the keypad is empty.

Further, if the key is pressed, the first digit of the key force is determined in step 52, and then the key force is read and the process moves to data storage processing step 57.The operation from now on will be explained below.

If a key from the second digit onwards is pressed, the calculation control unit 4o and memory read/write means 39 are operated to read which key on the dial 2 is pressed in the same way as the first digit reading operation, and the memory is read. The data is stored in the key buffer of section 38. This flow is shown in key reading data storage processing step 57 in FIG. Further, the arithmetic control unit 40 reads the digit data stored up to now in order to generate digit data indicating whether data for the side digits is stored in the key buffer, adds 1 to it, and sends the result to the memory read/write means. 39 to access the digit data address of the memory section 38. Next, in addition to shifting the key buffer in the memory unit 38 and reading the key data for next output, the memory unit 38 performs arithmetic control on the digit data that is stored in the key buffer to determine whether side digit data is stored. The data is read into section 40, where one digit is subtracted from the digit data, and the result is stored in the digit data address of memory section 38 again.

This flow corresponds to the data shift processing step 58 in FIG.
Reading of the shifted data and processing of the key buffer digit data is the output data setting 59 in FIG. The data to be output is sent to the arithmetic control unit “°7 Read 1”.
``Digit''p''4-'v'v Output Process 1 Output the dial pulse to the telephone line connection terminal 1 (Ll, L2) in the same way as 56. This flow is the dial output process 60 in FIG. .

Next, the operation when no key is pressed but data is accumulated in the key buffer will be described. When the caller has hooked up the handset 19, it is determined in the key force detection processing step 51 that no key has been pressed, and the arithmetic control section 40 operates the memory read/write means 39 to read the digits in the memory section 38. The data stored at the data address is read, and if there is no data, the process returns to the hook switch detection process 50, but if there is digit data, the process moves to the data shift process 58. The following output data setting step 59. Dial output processing step 6
0 and return to the initial mode. This flow is shown in key buffer empty state determination 61 in FIG. With the above operations, it is possible to read the key, output pulses, and output the own station number.

In addition, in FIG. 1, the control section 3 includes a key detection means 31, an arithmetic control section 40. This is a general term for the memory section 38, etc.

The incoming call detection section 7 is for detecting an incoming signal when the telephone receives a call, and generates a ring tone by vibrating a connected ring tone diaphragm 8. The power supply circuit 9 is a circuit that supplies power to the control unit 3 from the telephone line connection terminals 1 (Ll, L2). The battery 10 not only protects the data stored in the memory section 3, but also protects it only for a short period of time when the power from the telephone line connection terminal 1 (Ll, L2') is momentarily cut off during use.

The clock resistor 16 and the clock capacitor 17 are connected to the clock generating means 34 to operate as a clock generator for system operation of the control section 3.

The program section 32 is used to cause the entire system to operate according to the flowchart of FIG. 2 by means of a clock generating means 34.

Effects of the Invention As is clear from the above embodiments, the present invention provides each telephone with a local number setting device and a memory section for temporarily storing the called party's number, and when the called party's number is dialed. , this called party number.

The system is configured so that it is stored in the memory section, and the own number set using the own number setter is first sent, followed by the called party number in the memory section, so the main device can easily send the call number. It has the advantage of being able to identify the calling party's number, and allowing usage records and billing management to be performed on a telephone-by-telephone basis.
