Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention uses the operation indicator light of the equipment to notify operators and service personnel of the failure details and maintenance information when a failure occurs in equipment. The present invention relates to an apparatus and method for displaying failure and maintenance information.

(Prior art) When a fault occurs in a circuit or ancillary equipment connected to or inside a conventional device, a dedicated indicator light is provided on the display section of the device, and depending on the nature of the fault, this indicator light is lights up,
Failures and maintenance information were notified to the operator by turning off the lights or sounding the buzzer.

However, with this method, as the number of types of faults to be displayed increases, the number of indicator lights must be increased accordingly.

In recent years, the functions of devices have increased, their internal mechanisms and circuits have become more complex, and the amount of fault information has also increased. On the other hand, accurately notifying operators and service personnel of the occurrence of a failure, the location of the failure, and maintenance information is an essential condition for quickly and accurately repairing the failure.

Therefore, it is necessary to provide as many indicator lights as necessary to notify the details of the failure. However, the number of indicator lights becomes too large and is not practical. One possible method for reducing the number of indicator lights is to display maintenance information by combining the lighting and dimming of a plurality of dedicated lights. For example, by using a combination of turning on and turning off N indicator lights, 2N pieces of information can be displayed. However, this is also 23− when N=3.
1 = number of information 7 (excluding 000 <,), 2 if N = 4
``-1=Number of information 15 (excluding 0000), if N=5, 2''-1=Number of information 31 (excluding 00000), which cannot be taken very much. On the other hand, when N = 8, the number of information is 28-1 = 255' (excluding 00000000), but this increases the number of indicator lights, making it easier for operators to make reading mistakes when reading the display. There was a problem.

(Problems to be Solved by the Invention) As described above, conventionally, when dedicated indicator lights are provided to display fault and maintenance information, as the functions of the equipment increase, additional indicator lights must be added. In addition, in order to reduce the number of indicator lights, when fault and maintenance information is displayed by combining the lighting and extinguishing of the dedicated indicator lights mentioned above, it is recommended that the number of indicator lights be reduced to accommodate the increased functionality of the equipment. Display fault and maintenance information for -
5- I can't do it. On the other hand, if the number of dedicated indicator lights is too large, the operator is likely to make a reading error when reading the display.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a failure and maintenance information/display device that can display a large number of failure and maintenance information using a small number of operation indicator lights.

[Structure of the Invention] (Means and Effects for Solving Problems) According to the fault and maintenance information display device of the present invention, when a device fault occurs, a fault signal output according to the type of fault is detected. fault signal detection means; fault and maintenance information converting means for converting the detected fault signal into fault and maintenance information expressed in an N-digit 2P-base number assigned to each individual fault; The apparatus includes a fault and maintenance information display means that endlessly repeats displaying the fault and maintenance information from the eighth digit to the first digit, one digit at a time, on the operation indicator light.

Further, according to the fault and maintenance information display method of the present invention, the step of detecting a fault signal that is outputted in accordance with the type of fault when a device fault occurs, and the step of detecting the detected fault information in an N-digit 2P base number. converting the converted N-digit 2P into expressed fault and maintenance information;
The method is comprised of a step of storing failure information in decimal numbers, and a step of endlessly displaying the stored failure and maintenance information digit by digit from the Nth digit to the first digit at regular time intervals.

Specifically, failure and maintenance information is expressed in N-digit 2P notation. For example, "Fuse blown due to print motor heating. Replace fuse" is expressed as r275J. The display method is to arbitrarily select P lamps from the operation indicator lights and use them as failure and maintenance information indicator lights, with 2P and 2F- respectively.
1, 2F-2, ...22.21, 20 bit weighting, and 1 is defined as 1 for lighting and 0 for non-lighting.
Displays the 2P base digit of the digit with this combination of lighting and dimming,
This display is performed sequentially over time from the Nth digit (the most significant digit) to the first digit (the least significant digit) at regular time intervals (T). That is, when a failure occurs and the mode is set to display failure and maintenance information, all of the operation indicator lights turn off first, and after a predetermined time (T) has elapsed, the P
After the maintenance indicator lamp lights up for a specified time (T) to display the N-digit 2P digit of the highest digit corresponding to the N-digit 2P digit corresponding to the fault information, all indicator lights will turn on for a specified period of time (T). goes out. Next, the N-1st digit 2P digit is illuminated for a predetermined time (T), and then all indicator lights are turned off for a predetermined time (T). This is performed sequentially up to the 2P digit of the first digit of the least significant digit, and finally, all the indicator lights are turned off for the predetermined time (T). Repeat this operation sequence.

According to the device and method for displaying fault and maintenance information of the present invention, the fault information can be displayed in detail as maintenance information in response to equipment faults, so the operator or service person can see the blinking state of the indicator light. When a failure occurs, read information on where the failure occurred and what treatment is required (separately prepare a comparison table of the displayed N-digit 2P number and failure information) and take appropriate measures. You can take it.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a data terminal device showing one embodiment of the present invention.

In FIG. 1, the data terminal device 1 is roughly divided into a control section 2,
It is divided into an input/output section 17 and a power supply section 10. The input/output section 17 is an operation display section 3, a printing section 4, and a passbook inserter section 5.
, slip inserter section 6, MS (magnetic stripe) reading/writing section 7, passbook page turning section 8, purchase reading section 9
It consists of The control unit 2 also includes a line connection unit 11, an interface control unit 12, an input/output control unit 13, and a storage unit 1.
4, a character font 15, and an arithmetic unit 16.

This data terminal device is, for example, a bank ATM (Automatic Teller Machine).
e) and is connected to the host system via an R5232C communication interface.

FIG. 2 is a detailed diagram of a part of the operation display section 3. As shown in FIG.

As shown in FIG. 2, the display unit 3 is provided with a power indicator light 24 to indicate that power is being input, a ready indicator light 23, a reception indicator light 22, and an error indicator light 21 as operation indicator lights. . Also, as a switch, a recovery switch 20 and an operation light/failure and maintenance light changeover switch 25 are provided.
Or is provided. The recovery switch 20 plays the role of system reset to return the functions of the data terminal device to its initial state. Further, the operation light/fault and maintenance light changeover switch 25 determines whether the ready indicator light 23, reception indicator light 22, and error indicator light 21 indicate the operating status.
This is a switch that changes whether to display fault and maintenance information.

FIG. 3 is a flowchart of operation command processing for the input/output section 17, FIG. 4 is a flowchart of maintenance information display processing of this embodiment, and FIG. 5 shows the contents of fault information stored in the storage section 14 of this embodiment. show. FIG. 7 shows a portion of the circuit of this embodiment, which has a maintenance information display function.

Next, the operation of this embodiment will be explained with reference to the drawings.

First, the operation command processing for the input/output unit 7 will be explained with reference to FIGS. 1 and 3. The control unit 2 performs step 1
0] issues operations and commands to the input/output unit] 7 via the input/output control unit [3], the operation display unit 3, the printing unit 4, the passbook inserter unit 5, the slip inserter unit 6, and the MS reading and writing unit 7. , the bankbook page turning section 8, and the page/reading section 9, respectively, to perform predetermined operations. When each of the above-mentioned sections 3 to 9 completes a predetermined operation, the input/output control section 13
An operation end notification signal is issued to the In step 1-02, the control unit 2 waits for an operation completion notification from each unit 3 to 9. In step 103, the control section 2 receives the operation completion notification from each section 3 to 9 and determines whether each section 3 to 9 has normally completed its operation. When the control unit 2 determines in step 103 that the operations of each unit 3 to 9 have ended normally, the process returns to step 10 and returns to step 01.
Repeat steps 103 to 103. On the other hand, if it is determined in step 10B that there is a failure, the control unit 2 proceeds to step 20.
．． 0, the fault signals from units 3 to 9 in which a fault has occurred are converted into fault information. As shown in FIG. 5, the failure information is composed of, for example, 5 bytes of response status 301, error codes 302 to 304, and status word 305. The response state 301 indicates the presence or absence of a failure and a rough classification of the type of failure. For example, it is composed of 8 bits, and bit 0 indicates whether the error is a node error or a soft error, bit 1 indicates whether recovery from /'% error or soft error is possible, and bit 2 indicates whether there is an error. and bits 3 to 7 contain other information. Note that the information on bits 3 to 7 is not directly related to the present invention, so a description thereof will be omitted. Also, error codes 302 to 30
4 is made up of 3 digits, and each digit is made up of, for example, 8 bits =
12 - to be done. Further, the status word 305 is information representing details of failure information. For example, it indicates a command error in the printing unit 4, no paper, or a jam.

Therefore, from the response state 301 and the status word, the control unit 2 generates an error code in which the type of failure, the location of the failure, and the maintenance action for the failure are displayed in three-digit ophthalmology.

Returning to FIG. 3 again, the control unit 2 transfers the failure and maintenance information created in step 200 to step 201.
The information is stored in the storage unit 14 at the time. and step 201
At A, a fault and maintenance information display processing subroutine is executed.

FIG. 4 is a detailed flowchart of the failure and maintenance information display processing routine.

In step 202, the control unit 2 determines whether the switch 25 is in the operating light display or in the failure and maintenance display. If the operation lamp is displayed, the operation indicator lamp 21 is turned on in step 203, and the process proceeds to step 218.

On the other hand, if the switch 25 indicates the failure and maintenance lamp display in step 202, the control unit 2 performs step 21]. The failure and maintenance information display processing routines 217 to 217 are executed.

That is, in step 211, the control unit 2 turns off the ready light 23, ready light 22, and error light 21 for a time T, for example, one second. Next, in step 212, the third digit (hundreds place) of the error 7 code is lit for one second. Next, in step 213, all of the display operating lights 21 to 23 are turned off again for one second. Next, in step 2]4, the second digit of the error code is lit for one second. Similarly, in step 215, the operation indicator lights 2] to 23 are changed to 1.
The light is turned off for 1 second, and in step 217, the first digit of the error code is turned on for 1 second. For example, as shown in FIG. 6, in the case of a motor system power supply fuse blown failure, the error code is "71 code".

Then, the error light 21, the ready light 22, and the ready light 23 are given weights of 211.2'' and 23 (1 digit), respectively.If the result is ``711'' displayed, step 2
At step 12, all the ready lights 23, ready lights 22, and error lights 21 are turned on, and step 2]4 and step 2 are turned on.
At step 16, the error light 21 is turned on. This display is displayed repeatedly until the recovery switch 20 is pressed.

Operators or service personnel should use this operation indicator light 21.
The user reads the error code by looking at the blinking states of 23 and 23, and refers to the fault and maintenance information comparison table, a part of which is shown in FIG. 6, to learn the details of the fault and maintenance measures, and to perform corresponding processing. That is, the operator or service person presses the recovery switch 20. When the control unit 2 detects that the recovery switch 20 is pressed in step 218, it refers to the response status 301 in step 219 and determines whether it is a 1-F error or a software error. Step 221 in case of soft error
Proceed to. /'%- error, I10 initialization (I10 port is reset to the initial value) is performed in step 220. Next, in step 221, the system program area of the storage section 14 is initialized.

Next, in step 222, the failure and maintenance information area of the storage section 14 is cleared. Finally step 22
3, the error light 21, ready light 22, and ready light 23 are turned off. As a result, the data terminal device 1 is restored to the initial operating mode.

FIG. 7 shows an example of a circuit according to an embodiment of the invention. 401

404 is an address data bus, 405 is an I10 port that detects a fault signal or the state of the operation switch 20.25 and transmits data to the CPU 401, and also lights up the indicator light 21, 22, 23 according to a command from the CP or UT 401; 406
is a circuit for detecting a blowout of the motor system fuse 407 corresponding to maintenance No. 711 shown in FIG.

If the motor system power supply fuse 407 blows, the signal from the motor system power supply fuse blown detection circuit 406 will be transmitted to the I10 port 405.
is input to the CP via the address data bus 404.
Input to U401.

In addition, operation light - damage and maintenance light switching moxibustion switch 2
5 is similarly stored in a predetermined location of the battery backup RAM 40B via the I10 port 405, the address data bus 404, and the CPU 401, and by combining this data with the signal input of the detection circuit 406, Either operation indicator lights or fault and maintenance lights are displayed.

As mentioned above, in general, with P indicator lights, (2P)N
information can be displayed, but if all of the P displays etc. go out, it is difficult to recognize the information because it overlaps with the case where all the indicator lights go out between the digits. If this is removed, the number actually suitable for use is (2P-1)N. −
For example, if N=3 and P=3, the number becomes 343. N,
If P is increased, the number that can be displayed will increase dramatically, but considering the readability of the lamp display, it is not appropriate to increase it too much.

In this way, the turning on and off of the operation indicator light is the output port for the indicator light of the microcomputer circuit built into the equipment. During normal operation, the microcomputer outputs an operational display signal to the indicator light output port, and when a fault occurs, it outputs a fault display signal to the indicator light output port.Through these four steps, one display can be created. The light can be used in combination as an operation indicator light and a fault/maintenance information indicator light.

[Effect of the invention] As explained above, according to this invention, failure information can be
Expressed in digits in 2P notation, the output port signal for the operation indicator light of the microcomputer circuit built into the equipment is made into a signal for displaying maintenance information by a program, and P operation indicator lights are used together as maintenance indicator lights.N Since the N-digit 2P base number is displayed in times, an extremely large amount of fault information can be displayed as maintenance information using an extremely small number of indicator lights. This eliminates the need to provide a large number of fault indicator lights or maintenance information indicator lights for the equipment, and prevents an increase in the number of control circuits, display devices, and ultimately the size of the equipment, helping to reduce the cost and size of the equipment. In addition, since a large amount of maintenance information can be displayed, the information can be detailed, allowing quick and accurate repair work, or even if a failure occurs in a remote location where there are no skilled operators or service personnel. If you inform us of the numbers displayed on the maintenance light, we can instruct you on repair measures, which helps shorten failure recovery time and improve equipment operating efficiency.
