Description

[Detailed Description of the Invention] E-Industrial Application Field] The present invention relates to a public telephone that transmits alarm information when a failure is detected.

Conventional technology] Conventionally, public telephones of this type were disclosed in Japanese Patent Publication No. 1-37.
As disclosed in Japanese Patent No. 897, when a public telephone malfunctions and the malfunction is detected, alarm information is sent to a maintenance center regardless of the degree of malfunction.

In addition to the above-mentioned ones, there are also those disclosed in Japanese Patent Application Laid-Open No. 61-92069 and Japanese Patent Application Laid-Open No. 64-69154. All of these systems automatically answer an incoming call when a call arrives from the maintenance center, and also send alarm information to the maintenance center based on a detected malfunction of the public telephone.

[Problem to be solved by the invention] However, in the case of a public telephone that unconditionally sends alarm information to a maintenance center when a malfunction is detected, coins used are Alarm information is sent to the maintenance center even in the case of a temporary failure where the cause of the failure is in the card or a minor failure that does not directly affect calls. There was a problem that the judgment etc. became complicated.

Furthermore, in the case of public telephones that only send alarm information when receiving a call from the maintenance center, even if a fault is detected, the alarm information indicating the fault cannot be sent until the call arrives from the maintenance center. , there was a problem that public telephones were left out of order for a long time.

[Means for Solving the Problems] In order to solve such problems, the first invention of the public telephone according to the present invention provides a method for solving the problems when failures are continuously detected based on self-diagnosis related to outgoing call operations.

A fourth aspect of the present invention is provided with a usage counter that counts the usage status of a public telephone for each item, and means for determining a call destination based on a communication protocol when responding to an incoming call.

Moreover, the fifth invention is such that the content of the usage status counter is deleted after the information corresponding to the content of the usage status counter or the content of the usage status counter is transmitted.

Further, in a sixth aspect of the invention, the transmitting means transmits the contents of all usage status counters, and also transmits failure data or normal data detected based on the self-diagnosis results.

[Operation] When failures are continuously detected by self-diagnosis related to the outgoing call operation and the cumulative number of failures reaches a specified value, the corresponding alarm information and the telephone-specific management number are transmitted to the first destination.

Additionally, when the contents of the usage counter that counts the usage status of public telephones for each item reaches a specified value, information corresponding to the contents of all usage status counters and the management number are sent to the second destination. .

Furthermore, when failures are continuously detected through self-diagnosis related to call making/receiving operations and the cumulative number of failures reaches a predetermined value, and when a call is made, corresponding alarm information and a management number unique to the telephone are transmitted. Also, when the call is incoming, alarm information and a management number based on the self-diagnosis results are transmitted.

Additionally, the contents of all usage status counters are transmitted.

Furthermore, the contents of the usage counter are deleted after they are sent.

Furthermore, along with the contents of all usage counters, failure data or normal data detected based on the self-diagnosis results are also transmitted.

[Example] Next, the present invention will be explained with reference to the drawings.

OM, 17 is RAM, 18 is hook switch, 19 is start circuit, 20 is pw relay, 21 is GS relay, 2
Reference numeral 2 denotes a coin sorting section that performs sorting processing of coins inserted.

When an incoming call arrives on the line while this public telephone is in an idle state, this incoming signal is detected by the incoming call detection circuit 3 and the buzzer 4 sounds, and at the same time, this incoming signal arrives at the start circuit 19 and starts. One of the circuits becomes operational, and as a result, the PW relay 15 operates, its contact pW is closed, and the commercial power supply 1 is supplied to the power supply circuit 2. Then, the power supply E1 from the power supply circuit 2 is connected to the CPU.
15 to start up the CPU 1, and the power E2 is supplied to other parts. And CPU15
reads the charged voltage charged in the capacitor in the incoming call detection circuit 3 by the incoming call signal via the input/output circuit 13 to recognize the incoming call state, and also detects the off-footer of the hook switch 18 when the handset 8 is raised during the incoming call. If the condition is detected via the input/output circuit 14, it is treated as an incoming call. That is, by driving the GS relay 21 via the input/output circuit 13 and activating the contact gs, the incoming call is responded to and a conversation with the other party is permitted. In addition, if off-hook is still not detected even after a certain number of incoming signals arrive, a self-diagnosis process is performed at the inspection point that is slightly different from the case of the outgoing operation, which will be described later, and the GS relay 21 is driven to close the contact gs. Activate it to automatically answer this incoming call,
Information such as the results of the self-diagnosis diagnosed above is transmitted to the other party, ie, a maintenance center, etc.

Also, when off-hook for making a call, the hook switch 18 activates the start circuit 19 and the PW relay 2
0 becomes the operating state, and as a result, the commercial power supply 1 is supplied to the power supply circuit 2 and the CPU 15 is started up, in the same way as described above. At this time, the CPU 15 selects the hook switch 1.
It detects the off-hook state of 8 and recognizes that it is an off-hook state for making a call, performs a self-diagnosis process at a testing point that is slightly different from that for an incoming call, and drives the GS relay 21 to activate the contact gs. In addition to capturing the line,
Allow calls depending on the self-diagnosis results,
A billing signal that arrives in accordance with the call time is received, and a billing process is executed in which the inserted coin is stored or the number of calls is subtracted from the inserted card. When on-hook and end the call, information such as the self-diagnosis results diagnosed above is transmitted to a maintenance center or the like.

The self-diagnosis process described above is executed each time the CPU 15 is activated due to an incoming call or off-hook. If the inspection location is malfunctioning at this time, the corresponding malfunction counter is incremented by one, indicating that the malfunction has occurred. When the failure counters are continuously detected and the consecutive values of each failure counter reach a specified value, the maintenance center is notified. For those for which a notification is made when a single failure is detected, the handset 8. There are failures in various parts such as forced opening of the housing door, poor transportation of the card used in this public telephone, and failure to read card data.In addition, if a notification is issued after five consecutive failures are detected, the keyboard 11 There are failures at various locations, such as forgetting to lock the housing door, opening the housing door, and failure of the polarity reversal signal detection circuit for detecting the other party's response.

Further, cases where a notification is issued after 15 consecutive failures are detected include failures in setting switches for setting various functions, etc.

Next, the CPU in the public telephone configured as described above
The detailed operation of step 1.5 will be explained based on the flowchart of FIG.

First, when the power is turned on to the CPU 15, initialization processing is performed in step 50. Subsequently, in step 51, it is determined whether there is an incoming call. Then, when an incoming call arrives on the line and it is judged as "Y" in step 5]-, a self-diagnosis process is executed in step 52 to check the quality of the inspection points of this public telephone, and if a malfunction is detected, In step 53, all the counters corresponding to the detected failure point among the failure counters provided corresponding to the above-mentioned failure points are incremented by one, and in step 54, the GS relay is operated to respond to this incoming call. do. Thereafter, in step 55, communication protocol processing is performed with the other party to identify the other party. Then, it is determined whether the communication partner is the maintenance center, that is, it is determined in step 56 whether the call is received from the maintenance center, and if it is the maintenance center, the data in the corresponding failure counter or normal data is determined in step 57. RAM1
In addition, if the communication partner is not the maintenance center and it is determined as "N" in step 56, the communication partner is the call volume management center, and the use of this public telephone is determined in step 58. All the data in each usage status counter indicating the status and the data or normal data in the relevant failure counter are set in the transmission buffer in the RAM 17, and the process moves to step 59, where the contents of these transmission buffers are and the management number of this telephone to the maintenance center or call volume management center, clear the contents of the corresponding counter in step 60, and proceed to step 61 to perform hook processing such as call termination processing and end. . In addition, the number of calls, etc. for local calls, long distance calls, international calls, etc. are separately counted and stored in each of the usage status counters described above.

Then, no incoming call arrives on the line, and in step 51, "N
”, this means that the CPU 15 was activated due to a factor other than the arrival of an incoming call, such as off-hook, opening of the housing door, and removal of the safe. A fault diagnosis process is performed to diagnose the fault, and all counters corresponding to the fault location detected in step 71 are incremented by one. Then, in step 72, the hook switch circuit 10 is detected to determine an off-footer, and if the off-hook state is not present, the process immediately moves to step 61 to perform hook processing such as call termination processing.

If off-hook is detected and the determination is "Y" in step 72, the GS relay 21 is driven to close the loop in step 73, and the failure counter is checked and the off-hook is determined according to the degree of failure. A flag is set, and in step 73- it is determined whether there is a failure. If it is not determined that there is a malfunction, the call is permitted in step 75 and the process moves to step 76. If it is determined that there is a malfunction, it is determined in step 76 whether or not an on-hook flag is set. If no malfunction is detected, or if a malfunction is detected but is minor, a call is made to the other party by dialing the number of the other party, and as a result, coins are exchanged in response to the incoming billing signal in step 77. A billing process is executed to store the card or to subtract the call frequency from the card.

In addition, if the on-hook flag is set as a result of a severe failure, or if an on-hook is detected and the on-hook flag is set, the step knob 76 will return "Y", and in this case, the step 80 will be returned. It is determined whether or not there is a counter that has not reached the specified number of failure counters, and if this is determined to be "Y", the GS
After controlling the relay 21 to interrupt the loop for 800 m5, the line is re-captured, and in step 82, the fault data that has reached the specified number of times is sent to the buffer.
In step 83, the maintenance center is automatically dialed, and when the maintenance center answers, the contents of the sending buffer and the management number of this telephone are sent to the maintenance center in step 59, and the number of times specified is reached in step 60. The content of the corresponding counter is cleared and the hook processing from step 61 onwards is executed.

In addition, if none of the failure counters has reached the specified number of times, it is determined as "N" in step 80, and in this case, in step 84, the number of usage status counters indicating each usage status of the public telephone is determined as "N". It is determined whether there is a counter that has reached the specified number of times. If there is no usage counter that has reached the specified number of times, hook processing such as call termination processing is executed in step 61, but if there is a usage counter that has reached the specified number of times, the GS relay 21 is activated in step 85. After controlling the loop to interrupt the loop for 80'Oms, the line is reacquired, and in step 86 all the usage data that has reached the specified number of times is set to the transmitting port 7, and in step 87 it is sent to the call volume management center. When the call volume control center automatically dials and answers, step 59
At step 60, the contents of the transmission buffer and the management number of this telephone are transmitted to the call volume management center, and at step 60, the contents of the corresponding counter that has reached the specified number of times are cleared, and the hook processing from step 61 onwards is executed.

Although the present embodiment has been described with respect to a commercial power supply type public telephone, the present invention is not limited thereto, and can also be applied to cases where the commercial power supply 1 has a power outage and to a case where a central power supply type public telephone is used. That is, in these cases, it is sufficient to close the DC loop by hardware using an off-hook or incoming call signal, provide a capacitor, charge the local power supply to this capacitor, and start the CPU 15 with this charging voltage.

[Effects of the Invention] As explained above, the public telephone according to the present invention provides alarm information and the telephone when a failure is continuously detected by self-diagnosis related to the outgoing operation and the accumulated number of times reaches a specified value. Since the unique management number is transmitted to the first destination, it is possible to eliminate complicated management 1 judgments on the side of the first destination, that is, the maintenance center.

In addition, if a failure is continuously detected by self-diagnosis related to the outgoing/receiving operation and the cumulative number of failures reaches a specified value, and in the case of outgoing operation, the corresponding alarm information and management number will be sent, and the corresponding alarm information and management number will be sent. In this case, alarm information and a management number based on the self-diagnosis results are transmitted, making it possible to transmit alarm information every time a call is made or received from this public telephone, and as a result, the malfunction can be promptly repaired. It has the effect of
