Abstract

PURPOSE:To manage effectively a program by storing a managing number corresponding to a program of contents to a specific address of a nonvolatile memory in a device such as telephone set and reading and displaying the managing number as required by means of a processor. CONSTITUTION:When the personnel in charge inputs an objective code from a keyboard 17, the code is decoded depending on the combination of numerals. When an input code is, e.g., [00], the content of an RAM16 is read and a faulty part is displayed as a code by a display device 19. When the input code is [01], the management number stored in a specific address in an erasable PROM (EPROM)24 and displayed on the display 19. Generation of errors at replacement or confirmation of the content of the EPROM24 is blocked completely by storing the management number into the EPROM24 depending on the specific program at each stored telephone set.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

FIG. 1 is a block diagram showing the entire configuration of a telephone set. A line terminal 1 to which a line from a telephone office is connected is connected to an incoming call detection circuit 3 via a contact gsl of a relay GS provided in a main unit 2. is always connected, and when it detects the arrival of a calling signal, it drives the buzzer 4 and also controls the input/output circuit 5.
a and the bus 6 to a processor such as a microprocessor (hereinafter referred to as CPtJ). It is supposed to be given to and started.

Further, when the hook switch 8 generates off-hook information due to off-hook, the start circuit 9 responds and the relay G
In order to drive S and give start information to the CPU 7 via the input/output circuit 5b and the bus 6, the CPU
7 starts the corresponding control, while the contact gsl operates, and the billing signal receiving circuit 10 and the diode bridge 11
and the communication circuit 13 is connected to the line terminal 1 via the power supply circuit 12.
, and closes a DC loop to the line, allowing the handset 14 to make a call.

In addition, the power supply circuit 12 generates a local power supply E□ based on the line current that has a constant polarity through the diode bridge 11 in accordance with the flow of line current accompanying the closure of the DC loop, and is turned on. The current is supplied to each part through the contact gs2, but even during on-hook, a current to the extent that the exchange does not respond is passed from the break side of contact gs1, and this sends out the local power supplies F and 2, The power supply E2 is also supplied to circuits that require power supply and circuits that operate simultaneously with off-hook.

On the other hand, the CPU 7 is connected to the ROM via the bus 6.
The call processing program in 15 is executed and the similar RAM (
Random Acce+ss Menxor)',)
The control is performed while accessing the necessary data for EPRO 16, which will be described later.
The control data stored in M is used as necessary.

That is, in the case of a call, the signal generator 18 sends out a dialing signal using a composite audio frequency in response to the operation of the keyboard 17, the display circuit 19 displays the call charge, etc., and the charge signal received from the exchange The sorting and storage of coins by the sub unit 20 and storage mechanism 21 are sequentially controlled according to the charging information given from the charging signal receiving circuit 10.
Depending on the data in the PROM, free calls are allowed, calls to prohibited numbers are prohibited, etc., and if the switch transmits a billing signal only when responding to the called name, the EPROM According to the data in the system, coins corresponding to the unit call charge are stored every time the unit call time elapses, and when there are no more coins waiting to be inserted, the call is forcibly disconnected.

On the other hand, in the case of an incoming call, the relay GS is driven according to the off-hook information from the hook switch 8, the DC loop is closed, and the call is allowed. The CPU 7 determines that this is the case, and performs the various controls described above.

The sub-unit 20 also includes a measurement circuit 23 which is connected to each sensor provided in the storage mechanism 21 to detect the material, outer diameter, thickness, etc. of the inserted coin, and which records the measured values of the coin. An EFROM 24 is provided as a non-volatile memory in which the upper and lower limit values of the measured values are stored as unique coin sorting data. The CPU 7 determines whether the inserted coin is correct or not according to the measured value from the measuring circuit 23 and the coin sorting data in the KPROM 24, and controls the storage mechanism 21tl via the input/output circuit 25 to determine whether the coin is incorrect or not. It is used to return regular coins, accumulate and store regular coins, etc.

Note that control data etc. are also stored in the EPROM 24 as part of the call processing program.
It is used together with the call processing program in the OM 15 to regulate the control operation of the CPU 7.
A management number corresponding to the content is stored in the specific address.

In addition, a printed circuit board or the like is used for each unit 2, 20, the sub unit 20 is combined with a storage mechanism 21, and a space between the sub unit 2o and the main unit 2 is an extension from the sub unit 20. The cord and the plug connected to the tip thereof are electrically connected to the connector 26 of the main unit 2 in a detachable manner.

In addition, the housing of the telephone includes a housing switch 27.
If the housing door is opened during maintenance 1 inspection, the same switch 2T will be activated and this information will be sent to the CPU.
7 via the input/output circuit 5b.

FIG. 2 shows the overall control status 70- by the CPU 7.
In the chat, after performing "Initialization processing" 101 and "Self-diagnosis processing" 102, it is determined whether "On-hook flag is set?" 103, and if this is N (No), "Failure flag set?" 104 After determining this, perform 6 call permission processing "105" assuming this is N, and again "Set on-hook flag?" -”Judging 106,
If this is N, then the ``coin storage determination process'' 107 and the ``coin storage process'' 108 are performed, and steps 106 and subsequent steps are repeated.

Note that if step 104 is Y (YES), the process cycles to step 103 and does not proceed to step 105.

Moreover, if steps 103 and 106 result in Y, the drive of the relay GS is stopped by the "hook process" 109, and the DC loop is opened.

However, the programs related to steps 101 to 104 and 109 are stored in the ROM 15, and the programs related to steps 105 to 108 are stored in the EPROM 24.

Figure 31 shows that CPLT 7 is 4m5 with the control in Figure 2.
This is a 70-chart of an interrupt routine that repeats at the cycle of ec, and the shift switch 8. Measuring circuit 231, billing signal receiving circuit 10, keyboard 17. Accept each information from the housing switch 27 etc., and when on-hook, step 103 in FIG.
Set the on-hook flag corresponding to 106,
1 display processing 202 drives the display 19 to display the unused amount of coins that have been inserted and are waiting, and then 1 billing calculation processing 203 displays the unused coins in response to the arrival of the billing signal. After performing the subtraction from the amount, etc., perform the ``coin insertion process'' 204, determine the type of input coin, and add the accumulated amount based on the waiting coins, and then perform the ``1 timer process''. 205, storage mechanism 2
Monitoring of the excitation period for the storage magnet in the storage magnet 1, local call time, and time monitoring for various controls are carried out, and corresponding controls are carried out according to the elapse of the time set for these.

FIG. 4 is a flowchart of a lower routine showing the details of step 102 in FIG. It is checked whether the initial state of each part is as specified or not, and if a disconnection with the secondary unit 20 or any failure is detected, "Failure?" 303 is displayed. Y and Kashi, step 104 in FIG.
304 is performed.

Also, according to the information from the housing switch 27, it is determined whether the housing door is open or not, and if it is Y, a manual self-diagnosis process is performed for maintenance 2 inspection by the staff member.
Move to 30&.

@Figure 5 is a flowchart of a lower routine showing the details of step 306 in Figure 4. When the staff member inputs a code according to the purpose from the keyboard 17, a code is generated by "key manual processing" 401 according to the combination of numbers. For example, if the input code is "00", R
The contents of AM16 are read out, and the display 19 performs 6 fault location display processing 402 to display the fault locations detected in steps 301 and 302 in FIG. 4 as codes. If the input code is "01", , EPROM24
Read the management number stored in the specific address inside,
"Program management number display processing" 403 displayed on the display 19 is performed, and when the input code is 141, the drive signal for the storage magnet is sent out and "storage magnet drive processing" 404 is performed, and thereafter input is made in the same manner. After processing according to the code, set 1 off hook flag set 'i' according to Y of 405.
Step 401 and subsequent steps are repeated.

Therefore, by storing the management number in the EPROM 24 according to the unique program for each telephone stored therein, the management number can be easily and reliably confirmed as necessary. Tona υ, EPROM
When replacing 24 or checking the contents, the phone and EPROM 2
In combination with 4, the occurrence of errors is completely prevented.

Note that similar means can be applied to the ROM 15 depending on the situation.

However, the configuration in Figure 1 can be selected arbitrarily depending on the situation, and in Figures 2 to 5, steps may be replaced according to conditions, or unnecessary steps may be omitted. Various modifications are possible, such as setting an alarm flag in response to the detection of the alarm flag and sending an alarm to a maintenance center or the like accordingly.
