BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. However, the technical scope of the present invention is not limited to the embodiment. In the following description, a water heater with a bath reheating function will be described as an example, but the present invention can also be applied to a water heater having other functions or a general combustion device.

FIG. 1 is a diagram showing the overall configuration of a water heater repair support system. Reference numeral 1 is a repair support device for the water heater 2 via a communication medium such as a communication line or infrared rays.
Connected to. The repair support device 1 includes a portable terminal, a portable personal computer 10, and an input / output box 2.
It consists of zero. The mobile terminal 10 can be a general-purpose product, and various repair support functions can be realized by installing a repair program.

The mobile terminal device 10 is connected to the input / output box 20 by a communication cable line such as RS232C, and the input / output box 20 converts the digital signal supplied from the mobile terminal 10 into a voltage to match the voltage of the water heater 2. The power transmitted from the digital signal serially or detected from the water heater,
It has an interface function of converting analog values such as gas pressure, current, voltage, resistance value, and frequency into digital values and transmitting them to the mobile terminal 10.

The water heater 2 is provided with a control device by a microcomputer, which will be described later, but is connected to the input / output box 20 by a communication line CN5, and the portable terminal 10 is connected.
Is able to analyze the inside of the controller of the water heater. Further, for the water heater 2, a terminal CN4 for detecting electric power consumed with respect to the commercial power source, a tube CN3 for measuring the secondary gas pressure, and a voltage, current, resistance of a selected portion. A terminal with probe CN2 for measuring the frequency is attached.

Therefore, what is required of the water heater 2 is:
Basically, a connector terminal to which the communication line CN5 is connected,
It is a communication function performed via the communication line.

FIG. 2 is a diagram showing the configuration of software functions in the portable terminal 10 of the repair support device. The mobile terminal has a hardware configuration equivalent to that of an ordinary general-purpose computer, and the software having the functions shown in FIG. 2 is stored in the storage medium.

The tester function P1 has an AC / DC voltage measuring function P11, an AC / DC current measuring function P12, a resistance measuring function P13, and a frequency measuring function P14. These tester function programs P1 measure the voltage, current, resistance, and frequency of the selected site in the water heater by the terminal CN2 having the probe from the input / output box 20 described above.

The gas pressure measuring function program P2 is a program for measuring the gas secondary pressure downstream of the gas proportional valve in the water heater 2 through the above-mentioned tube CN3. Similarly,
The power consumption measurement function program P3 is a program for measuring the power consumed by the entire water heater via a power terminal CN4 inserted between the power source of the water heater 2 and the commercial power source.

These measuring function programs measure the respective physical quantities by controlling the measuring hardware in the input / output box 20, and the portable terminal 10
To display.

The device information acquisition function program P4 is a program for acquiring the model code and version information of the water heater connected via the communication line CN5.

The password function program P5 has a function of transmitting a special start instruction code for instructing the repair mode from the portable terminal 10 to the water heater 2 and receiving the reply.
As will be described later, in the repair mode, the memory of the control device in the water heater can be accessed, and there is a risk of rewriting or clearing the data essential for combustion control.
Security is ensured by sending and receiving passwords and confirming them.

The maintenance monitor function program P6, the simulated remote control function program P7, the individual component drive function program P8, and the failure diagnosis support function program P9 are the central parts of the failure support function of the present invention. To briefly explain the function of each program, the maintenance monitor function monitors the value of the sensor in the water heater and the numerical value for control, and it is possible by reading the data in the memory (RAM) of the control device. is there.

The simulated remote control function program P7 displays a screen equivalent to the remote control on the display screen of the portable terminal, issues a command of a normal combustion sequence given from the normal remote control, hot water supply temperature obtained from the normal remote control, etc. Monitor the data of and change the set temperature setting. With this function, the repair worker can operate and monitor, for example, the remote controller in the kitchen or the bathroom while being in front of the water heater, thereby improving the repair workability. Specifically, it is possible by rewriting the flag, which means execution of the control sequence of the control RAM area in the water heater from the mobile terminal, to the ON state.

The individual component drive function program P8 has a function of individually driving actuators such as electromagnetic valves and fan motors in the water heater. The simulated remote control function gives a normal control sequence command from the mobile terminal, whereas the individual component drive function is a function of individually driving each actuator. Specifically, this can be done by rewriting a flag, which means driving each actuator in the control RAM area in the water heater, to an ON state from the mobile terminal, or giving an instruction to call a driving subroutine.

By performing the maintenance monitor function P6 at the same time as the simulated remote control function P7 or the individual component drive function P8, more efficient failure diagnosis can be performed. That is, it is possible to give a command of a normal combustion sequence from the mobile terminal 10 by the simulated remote control function and monitor the movement of the water heater at that time in the control device by the maintenance monitor function. At that time, it is also possible to simultaneously use the tester function P1, the gas pressure measuring function P2, and the electric power measuring function P3 to monitor their physical quantities. Further, it is also possible to drive the selected actuator by the individual component drive function and similarly monitor the movement or physical quantity in the controller of the water heater at that time by the maintenance monitor function or the like.

The maintenance monitor function P6, the simulated remote control function P7, and the individual component drive function P8 only send predetermined digital signals to the controller of the water heater through the communication line.

Further, these functions P6, P7 and P8 are
It needs to be commonly used for different devices from different manufacturers. Therefore, the program in the mobile terminal 10 is provided with a file P103 of data unique to each maker and model and a program. That is, it is a program required for monitoring the contents of the RAM through a communication line, executing a normal combustion sequence, and driving individual actuators, which is different for each maker or model. This program P103 is also used by the password function program P5 described above.

The fault diagnosis support function program P9 is
Even if they do not have the skill of repair, they provide diagnostic support to identify the failed part. For example, a function P91 for making a diagnosis by using an error code (a three-digit code standardized by the Gas Association) as a clue when the water heater fails, a function P92 for making a diagnosis by using a part of the water heater as a clue, and It has a function P93 or the like for making a diagnosis based on a state of a phenomenon or a defect.

This failure diagnosis support function program P9
It is necessary that a considerable part of each is created differently for each maker or each model. Therefore, the program P103 of the model-specific file group includes a diagnostic support program for each maker or model required in the program P9.

With respect to the above-described software, the present invention mainly uses display control and input control so that a repair worker can perform repairs on a common display screen and input operability via a portable terminal. There is a repair application program that is common to all models, and a file for each model that realizes different failure diagnosis support functions, maintenance monitor functions, simulated remote control functions, individual component drive functions, etc. for each water heater model. . The configuration of such software common to all models and the files different for each model will be described later in detail.

In this program, for example, when the simulated remote controller function program P7 is selected, the maintenance monitor function program P6 monitors the data in the RAM in the water heater, and at the same time the physical quantities such as voltage, electric power and gas pressure from the probe are detected. It is constantly monitored and displayed on the mobile terminal 10. Similarly, when the individual component drive program P8 is selected, the maintenance monitor function program P6 and the tester function P are also selected.
1. The gas pressure measuring function P2 and the power consumption measuring function P3 are simultaneously executed.

When the failure diagnosis support program P9 is selected, the physical quantities, power and gas pressure from the probe are monitored by the programs P1, P2 and P3.

Tube CN3 for measuring gas pressure described above
Is installed on the downstream side of the gas proportional valve in the figure. The power measuring terminal CN4 is connected to a power supply line of a water heater (not shown) to measure the amount of power consumption of the entire water heater.

FIG. 4 shows a control unit for controlling each actuator and sensor of the water heater shown in FIG. 3, which includes a CPU 41 such as a microcomputer and an EEPROM 4 connected thereto.
It is composed of 8. Reference numeral 47 is a remote controller attached to the kitchen or bathroom. In the CPU 41, in a normal configuration, the arithmetic unit 42, the drive state of the actuator, the output of the sensor, the RAM 43 that stores data such as flags and constants used in the control sequence, the ROM 44 that stores the control program and constants, A / D, D / A converter 45,
The interface 46 is connected via a bus.
The EEPROM 48 stores error data, its history, various setting constants, and the like.

Then, a drive signal is supplied from the CPU 41 to each actuator described in FIG. 3 via the interface 46, and the detection data from the sensor is received.

In the present invention, the portable terminal 10 as the failure diagnosis device is provided with the two-core communication line 4 via the input / output box 20.
9 is connected to the CPU 41. 50 is the communication line 4
It is a connector for connecting 9. In the present invention, it is required to add this connector 50 as hardware to the water heater side.

FIG. 5 is a diagram showing the structure of a control program for the water heater. The ROM 44 of FIG. 4 has a normal combustion sequence control unit T1 as a combustion control sequence program for controlling a normal combustion sequence such as hot water supply, automatic heating, and additional cooking. In this normal control sequence program, combustion control, communication with a remote controller, actuator driving, sensor value input, etc. are performed. It also has a communication control unit T2 with the outside. The communication control unit T2 with the outside is a program necessary for communicating with the failure diagnosis device this time,
This is the configuration required for the water heater in terms of software. In terms of hardware, it is the connector 50 as described above.

In the normal combustion sequence control section T1, when the operation start command signals for hot water supply, automatic operation, additional cooking, etc. are received from the remote controller side, for example, a flag in the RAM 43 indicating execution of these programs is turned on. Those controls are executed. Then, the state of the sensor is stored in the RAM 43.
Data that is detected from the data stored in the RAM and that commands the drive of the actuator necessary for combustion control is stored in the RAM 43.
Write to the corresponding area in. The command data written in the RAM 43 is given to the actuator as a command signal.

[Fault Diagnosis] The above is the description of the overall configuration. In the failure diagnosis device of the present invention, the hardware and software to be added to the water heater side are limited to a very small amount so that they can be used universally for all models of all manufacturers. ing. In order to make the failure diagnosis device as versatile as possible, the software configuration in the mobile terminal that performs the failure diagnosis is divided into a general-purpose portion and a corresponding program portion that differs for each model. Figure 2
The program P103 is a part of the program required for each supported model.

However, combustion devices in recent years are generally subjected to combustion control by a general-purpose microcomputer, and the RAM areas and control programs shown in FIGS. 4 and 5 are the same. Therefore, the details of the type of parts in the water heater, the address of the RAM 43, the program for entering and leaving the RAM area, the program for driving the actuator, the program for inputting the sensor data, and the like are different for each model. Furthermore, the repair support system of the present invention is provided with a failure diagnosis support function for repair workers who are not skilled, but this part also differs depending on the model. Therefore, in the present invention, those portions that cannot be made common are the program P103 described later.
Is dealt with by. On the other hand, in order to provide a repair worker with a common display screen and operability for each model, a repair application program is provided in which control of display and input to the repair worker is made common.

FIG. 6 is a flowchart of the entire repair support. In the figure, the process numbered with S is a step by the repair support device, and the process numbered with K is a step on the water heater side. Further, FIG. 7 is a detailed partial flowchart thereof.

At the start of repair, a repair worker carries the portable terminal 10 which is the repair support device and the input / output box 20 to the installation location of the water heater, inserts the communication line 49 into the connector 50 of the water heater, and connects the gas tube. CN3 is attached to the secondary pressure measuring unit, and power measuring terminal CN4 is attached to the power source (S
1).

Then, the main screen is displayed on the display screen of the portable terminal 10, and the repair worker turns on the start button (S2). Along with this, the password is transmitted from the mobile terminal 10 to the water heater as a code instructing the start of the repair flow (S3).

On the water heater side, after checking the transmitted password and confirming that it is a correct code, information such as the model and manufacturer of the water heater is returned and the software enters the repair mode. (K2). In particular,
Set the communication control program T2 with the external device to the running state,
For example, writing and reading to the RAM area in the microcomputer are permitted.

On the portable terminal side, the water heater information is received and the corresponding program is selected from P103 (S
4). As a result, the mobile terminal 10 becomes a repair support device dedicated to the connected water heater. In this way, acquiring device information from the water heater side is a very effective method for universally providing repair support for many types of devices. Further, it is possible to save the trouble of the repair person checking the model number of the water heater and inputting the number, thereby preventing an accidental input by mistake.
Further, even with the same model number, it is possible to support a version upgrade in which a minor correction is made to the program of the control device. Of course, it is necessary to keep the program P103 up to date.

Next, the repair worker selects a menu from the main screen (S5).

As the whole flow, as shown in FIG. 6, the maintenance monitor program is selected (S6), the simulated remote control program is selected (S7) or the individual component drive program is selected (S8), or the failure diagnosis is performed. After selecting the support program (S9), all repairs are completed and the end button of the main menu is pressed (S1).
0). As a result, the password, which is a code for instructing the end of repair, is transmitted from the mobile terminal 10 (S11). After confirming that the password is correct on the side of the water heater, the microcomputer 41 is reset to clear the data in the RAM forcibly rewritten during the repair (K3). This reset can use the reset function of a normal microcomputer. As a result, the water heater returns to the normal control mode.

[Maintenance Monitor Function] FIG. 8 shows an example of a screen displayed on the portable terminal when the maintenance monitor function is selected. FIG. 8A is a maintenance monitor selection screen, and FIG. 8B is its display screen. As shown in the detailed flowchart of FIG. 7, when the maintenance monitor function is selected (S9), the maintenance monitor selection screen (FIG. 8A) is displayed. As can be understood from the example shown in FIG.
What is monitored is the data stored in the RAM 43 such as the data from each sensor and the measurement time required for combustion control, which is constantly updated. Therefore, when the worker selects an item to be monitored and clicks the execute button (step S61), the maintenance monitor program controls to constantly read the data of the corresponding address in the RAM 43 in the water heater. Then, as shown in FIG. 8B, the selected item is converted into a specific physical quantity that is easy to understand and displayed (steps S62 and S63).

As described in the control of the water heater, in the combustion sequence control section, the control information is always written and read in the area in the RAM 43. Therefore, to monitor the state of combustion control, it is very effective to monitor the inside of the RAM 43. Therefore, by providing the program for reading the RAM 43 in the water heater of the corresponding model by the program P103, the mobile terminal 10 can constantly monitor the movement in the water heater.

By combining this maintenance monitor function with a simulated remote control function or an individual component drive function, which will be described later, it is possible to monitor the movement within the control section of the water heater step by step, and to identify the failure part in the repair or to determine the cause of the failure. The workability to detect is dramatically improved.

[Simulated Remote Control Function] FIG. 9 is a diagram showing an example of a screen when the simulated remote control function is selected. This screen is the same command button as the remote controller connected to the compatible model,
Status lamps, temperature, water level, etc. are displayed. When this simulated remote control function is selected, the portable terminal emulates the remote controller 47, and the repair worker can instruct the water heater by the remote controller from the portable terminal screen to perform a normal combustion sequence. That is, when the operation button is turned on and the command button is enabled, and then the automatic button is clicked, the water heater executes the automatic sequence program. Also, the temperature poured into the bathtub is changed by changing the bath temperature setting.

The method of instructing from the remote controller differs depending on the model and manufacturer. For example, by simply writing on-data to a flag of a predetermined area of the RAM 43 in the water heater, the control program on the water heater side then detects that a command is issued by referring to that area of the RAM, and Start executing the sequence. Alternatively, a subroutine program that calls the control program according to a command from the remote controller is executed. Appropriate processing according to each model is performed by the selected program P103 (step S7).
2).

FIG. 11 shows an example of the main screen when the maintenance monitor function and the simulated remote control function are selected. The simulated remote controller screen of FIG. 9 is displayed on the right side of the screen area 63, and the maintenance monitor display screen of FIG. 8B is displayed on the left side. Monitor items that match the sequence to be executed by the water heater by the simulated remote control function are selected in advance from the maintenance monitor selection screen of FIG. 8 (A). Then, the maintenance monitor display screen for simultaneous display can be viewed from the mobile terminal while causing the water heater to execute the sequence specified by the simulated remote control function. At that time, at the same time, the tester, the power consumption, and the gas pressure can be confirmed in the area 62. In this way, the internal state of the water heater can be observed one by one by operating the remote controller, and the work efficiency of identifying the failed part is dramatically improved.

[Individual Component Drive Function] FIG. 10 is a diagram showing an example of a screen when the individual component drive function is selected. Figure 10
(A) is a selection screen thereof, and shows a list of actuators which the connected target model has and which can be individually driven from the repair support device side. FIG. 10 (B)
Is an individual drive instruction screen for instructing specific drive content of the actuator selected thereby. As shown in FIG. 7, when the component to be driven is selected on the screen shown in FIG. 10A (S81), the screen shown in FIG. 10B is displayed and the drive instruction content is set within the screen (S82).

As a result, the processing required to drive the component (actuator) selected from the mobile terminal 10 is given to the microcomputer of the water heater via the communication line. The specific processing is, as in the simulated remote controller, rewriting to drive state data at a predetermined address in the RAM 43 or calling a necessary subroutine. This point is also executed by the program P103 different for each model.

In the example of the screen of FIG. 10B, it is possible to give the fan motor an instruction as to how many rotations the fan motor should be operated or at which it should be stopped. Each instruction content can be set for the igniter.

FIG. 12 shows an example of the main screen when the individual component drive function and the maintenance monitor function are selected at the same time. Figure 1
Similar to the case of 1, the individual component drive instruction screen of FIG. 10 is displayed on the right side of the region 63, and the maintenance monitor ideographic screen is displayed on the left side at the same time. In advance, a component that needs a drive check in the failure diagnosis is selected on the individual drive selection screen of FIG. 10A, and an appropriate button is clicked on the individual drive instruction screen on the right side of FIG. 12 to drive the inside of the microcomputer at that time. The state of can be monitored on the maintenance monitor display screen on the left.

On the main screen, the power consumption and the gas pressure are constantly displayed in the area 62. Therefore, as the simplest diagnosis method, it is possible to check whether or not the actuators can be operated by sequentially driving all the actuators by the individual component drive function and monitoring the change in the power consumption thereof.

By using the simulated remote controller function and the individual component function in combination, for example, the normal combustion sequence which does not operate normally described by the consumer is first executed by using the simulated remote controller function, Monitor activity. Then, based on the prediction of a certain degree of failure portion based on that, the selected component is driven by using the individual component drive function, and the internal operation is monitored.

Such repair work is effective for a worker having a certain degree of skill. The present invention provides the following failure diagnosis support function so that repair assistance can be provided even for an operator who does not have such skill.

[Failure Diagnosis Support Function] FIG. 13 shows an example of the first scene when the failure diagnosis support function is selected.
This failure diagnosis support function allows an operator, whose repair skill is not so high, to finally identify the failure part while talking with the mobile terminal. FIG.
Is an example of the first screen, but as shown in FIG. 7, the failure part is specified while calling the lower screen in a conversational manner.

As shown in the example of FIG. 13, for example, a menu for specifying the failed part based on the error code output from the water heater, a menu for specifying the failed part based on the part, and a phenomenon of the failure And a menu for identifying the failure part based on the defect. Other menus can be added if there are valid diagnostic clues.

FIG. 14 is a diagram showing a database example of a failure diagnosis support program. In the example of this database, for example, the lower layer screens associated with each other in a relational relationship are shown. Therefore, Roman numbers in the figure indicate the depth of the hierarchy. In this example, assuming that the main menu is the Ith layer, it has up to the V layer. The layer II has a screen 71 displayed when a menu based on the error code is selected. Since the error code is normally stored in the EEPROM 48 on the water heater side, when this menu is selected, the data is read out and displayed by the mobile terminal 10 through the communication line.

Then, when an error code is selected from that screen, the screens 72 and 73 of hierarchy III are displayed. This screen is a list of parts that should be checked or have a possibility of failure for each error code. Since the part list corresponding to the error code differs for each model of each water heater, the data of this screen is given by the program P103. In the example of FIG. 14, the screen 72 of the error code 1 is
The fan motor, hot water supply gas valve, switching gas valve 1 and igniter are listed.

Then, when the fan motor is further selected from the list, the screen 74 of hierarchy IV is displayed. On this screen, a list of check items necessary for diagnosing whether the fan motor is normal or not is displayed. For example, when the item of applied voltage is selected, the screen 76 of the layer V is displayed. On this screen, a message indicating what the worker should do in order to diagnose the voltage applied to the fan motor and the allowable range of the voltage are displayed, for example. As an example message,
"Remove connector xx and apply the probe."
According to that, when the worker hits the probe according to it, the program automatically drives the fan,
The voltage at that time is measured and displayed in the area 62 of the screen. The program automatically checks whether the voltage is within the allowable range and displays a message instructing some next work (not shown in the figure).

In this way, the worker can talk in FIG.
The faulty part is finally specified while moving between the inner layers or between the screens in the layer.

The database shown in FIG. 14 has a relational relation. For example, the hot water supply gas valve on screen 72 and the hot water supply gas valve on screen 73 of hierarchy III are associated with the same screen 75.

As another example of the fault diagnosis support function, the repair worker does not select the route to the upper and lower layers as shown in FIG. 14, but the repair worker simply selects a YES or NO button. Alternatively, the route may be automatically selected on the program side. FIG. 15 is an example of a lower layer screen used in such a case. This example is a screen when checking the rotation operation of the combustion fan, but basically this lower screen only displays a certain question message and YES and NO buttons entered by the repair worker. Is. A screen as shown in FIG. 15 is automatically displayed according to the failure diagnosis procedure specified by the failure diagnosis support file described later, and the repair worker can reach the failed part by simply clicking the YES or NO button. it can.

FIG. 16 is a diagram showing a database example of a failure diagnosis support program based on parts. For example, if the user gives more specific information about a part that has a bad condition, or if there is a possibility that the part may be specified, select this menu to support the failure diagnosis of that part. To be done. Level II screen 81
Is a list of parts, screens 83, 84 of hierarchy III are a list of items to be diagnosed in each part, and screens 85, 86 of hierarchy IV are message screens for diagnosis. Since layers II and below are different for each model, program P
Supported by 103. Also in this case, the faulty part is finally specified while moving the screen between the layers or within the layer.

FIG. 17 shows an example of a database for diagnosing a defect. When this menu is selected, a list of typical defects peculiar to the model is displayed on the screen 91 of hierarchy II. For example, the hot water supply temperature does not rise or there is a vibration noise. Then, it is selected from this list based on, for example, a defect due to information from the user or a defect when the normal sequence is executed from the simulated remote controller. Then, the screen 92 of the layer III shows a list of parts to be diagnosed when there is a problem that the hot water supply temperature does not rise. After that, in the same way as the above-mentioned case, the screen of Tier IV 9
The failure part is specified using the message screens 95 of the layers 3, 94, V, and the like.

In the case of this example, since the layers from the layer II onward are different for each model, they are supported by the program P103. In this way, the worker finally specifies the failed portion while moving interactively between the layers in FIG. 16 or between the screens in the layers.

The repaired part identification work is performed while moving between the screens based on the error codes, the screens based on the parts, and the screens based on the defects in FIGS. 14, 16 and 17 described above. . Therefore, it is possible to move between the respective hierarchical screens.

In the above description, an example in which the repair support device and the combustion equipment such as a water heater are connected via a communication line has been described, but the present invention is also applicable to the case of wireless communication via a communication medium such as infrared rays. Applies.

[Software configuration of repair support system]
As described above, the repair support system of the present invention can be applied to a plurality of types of combustion equipment, and provides a repair worker with a common display screen and operability for any combustion equipment. . By doing so, even if the combustion equipment is procured and sold by the multi-vendor method, repair support can be provided to all types of devices by the same repair support system. Although the software function has been described with reference to FIG. 2, the common part of the software and the part different for each model will be described below.

FIG. 18 is a module configuration diagram of software of the repair support system. A diagnostic application 100, a diagnostic sequence analysis means 101, and a communication driver 104 are provided in common in order to provide a repair worker with a common display screen and operability. In order to support a plurality of types of devices, a diagnostic sequence file 106, a simulated remote control file 107, an individual component drive file 108, a maintenance monitor file 109, and a conversion driver 110 are provided for each model as a model-specific file group P103. To be

The diagnostic application 100 includes (1) a display control function for displaying the screens shown in FIGS. 10 to 16 and 18 on the monitor 105 of the portable terminal, and (2) repair when the failure diagnosis support function is selected. A function of giving input data from a worker to the diagnostic sequence analysis means 101, and (3)
A function of giving a command to the conversion driver 110 by a repair worker's input operation when a basic support function such as a simulated remote controller, individual component drive, and maintenance monitor function is selected;
(4) Conversion driver 1 for command to execute tester function
Give to 10. (5) The diagnostic sequence analysis unit 101 has a function of relaying the command acquired when the diagnostic sequence file is syntactically analyzed and giving it to the conversion driver 110.

Since this diagnostic application 100 is used in common for all models, in addition to the display screen data shown in FIGS. 8 to 13 and 15, it simply has the functions of display, transmission, and transfer. It does not analyze the type or contents of the commands sent or transferred.

The diagnostic sequence file 106 stores a data file for realizing a failure diagnosis support function for each model in a simple syntax structure (database structure). Then, the data in the diagnostic sequence file is prepared for each model according to a grammar that has been agreed in advance. The diagnostic sequence analysis means 101 analyzes the syntax of the data in the diagnostic sequence file 106 according to the grammar, gives a message or question message to be displayed to the diagnostic application 100, and diagnoses the answer input data input by the repair worker. Application 1
Receive from 00. In addition, the diagnostic sequence file 10
The syntax in 6 is analyzed, and the acquired command is given to the conversion driver 110 via the diagnostic application 100.

Of the failure diagnosis support functions described with reference to FIG. 2, a diagnosis sequence file 106 is provided for each model in order to perform failure diagnosis support based on an error code. Before explaining the contents of this file, an example of the flow of failure diagnosis support will be explained. FIG. 19 is a diagram showing an example of the flow of failure diagnosis support. In this example, FIG.
As shown in Fig. 15, instead of letting the repair worker select each time when moving to the lower hierarchy, the parts to be diagnosed are selected according to the sequence stored in the diagnosis sequence file, and the repair worker displays as shown in Fig. 15. All that is required is to answer YES or NO to the question displayed on the screen and replace the parts according to the message.

Therefore, in FIG. 19, the data in the diagnostic sequence file 106 is a relational one having a hierarchical structure, but the data displayed is the lowest layer 125 or 1.
28 is a message and a YES / NO selection button.

First, the error code 1 is EEP in the water heater.
If it is stored in the ROM 48 and displayed on the display unit or remote controller of the water heater, the sequence table 12 indicating from which system of the plurality of systems in the water heater the failure diagnosis should be performed.
According to 1, the system to be checked first is automatically selected. The order table 121 is stored in the diagnostic sequence file 106 and analyzed by the diagnostic sequence analysis means 101. In the example of FIG. 19, it is shown in the start column that the diagnosis is first performed from the fan system among the three systems of the fan system, the gas valve system, and the igniter system. The order table 121 is variably set so that failure diagnosis is performed in order from the system in which the model is most likely to fail according to the failure rate or the like.

Then, for the fan system as indicated by 122 in the figure, the part to be checked first for failure diagnosis is again selected according to the order table 123. For example, in FIG.
When the combustion fan motor is selected as described above, a message or a question message is sent from the diagnostic sequence analysis means 101 to the diagnostic application 100 according to the data of the combustion fan motor portion of the diagnostic sequence file 106.
A message or question message is displayed on the monitor screen together with YES and NO buttons as indicated by 125 in the figure.

In the example of FIG. 19, when no abnormality is found in the combustion fan motor and the a sensor in the fan system,
The failure diagnosis of the fan system ends. Then, returning to the upper layer, the system to be subjected to the next failure diagnosis is selected according to the order table 121. According to Table 121, the gas valve system is selected as the target of the next failure diagnosis. Furthermore, the sequence table 126 for the four valves that are the target of failure diagnosis in the gas valve system is referred to. Then, as shown in the table, for example, a proportional valve is selected. A message or question such as 128 and YES and NO buttons are displayed for failure diagnosis of the proportional valve.

The answer data from the repair worker is given from the diagnostic application 100 to the diagnostic sequence analysis means 101, and the next message or question is displayed according to the answer, or the command to the water heater is converted by the conversion driver 110. Via the diagnostic application 100.

When the failure diagnosis of the proportional valve is completed and no abnormality is detected, the next failure diagnosis target portion is selected again according to the order table 126.

As described above, the flow of the failure diagnosis support is hierarchized, and the diagnosis target in each hierarchy is reciprocated between the lower hierarchy and the upper hierarchy while selecting the diagnosis target in the order table indicating the priority.

FIG. 20 is a structural diagram of the diagnostic sequence file. As described above, the syntax of the data in this file is constructed by a relatively simple grammar and is analyzed by the diagnostic sequence analysis means 101 common to the models. In addition, the data in this file is descriptive and is a high-level language that can convey the diagnostic sequence to repair workers. Therefore, the repair worker or the designer of the diagnostic sequence can easily understand.

As described with reference to FIG. 19, the structure of this file has, for each diagnostic system, a diagnostic procedure for a diagnostic site and an order table which is diagnostic route information indicating the order of each diagnostic site. The diagnosis procedure for the diagnosis part has a message or a command.

In FIG. 20, reference numbers in FIG. 19 are attached to clarify the relationship between the two. In the embodiment of the present invention, the plurality of systems 122 in FIG. 19 are indicated by 122a, 122b, 122c in the diagnostic sequence file. These systems are composed of a group of data that begins with “series =“ fan system ”” syntactically. Then, in the system 122a, "site =" fan motor "" is syntactically defined.
Included is a procedure for diagnosing a part beginning with “etc.” and a sequence table that is syntactically composed of “= {fan motor, a sensor} = {1,2}”. Furthermore, the diagnostic procedure for each part is "begi
n .... end ”. In the example of FIG. 20,
The data of the diagnosis contents of the diagnosis part 127 is described in the system 122b as shown in the example in the figure. In addition, the system 122a
For that, the order table 123 is given. Furthermore, for a plurality of diagnostic systems 122a, 122b, 122c,
An order table 121 for giving the order of the lines is included.

By referring to the example of the diagnostic sequence file shown in FIG. 20, it is understood that the flow of the failure diagnostic support shown in FIG. 19 is executed by the diagnostic sequence analysis means 101 and the diagnostic application 100. The syntax of the data in the diagnostic sequence file 106 is created according to the simple grammar as described above, and is analyzed by the diagnostic sequence analysis means 101 common to the models. Then, in accordance with the sequence shown in the file 106, a component for failure diagnosis is automatically selected, a message to the repair worker is displayed on the monitor 105 by the diagnostic application 100, and the data of the answer to that is diagnosed from the diagnostic application 100. It is returned to the sequence analysis means 101.

The diagnostic sequence analysis means 101 analyzes the data in the file 106 according to the response data, and proceeds to the next diagnostic procedure. In addition, the diagnostic sequence file 10
When the command for the water heater in 6 is acquired, the diagnostic sequence analysis means 101 gives the command to the conversion drive 110 via the diagnostic application 100.

Diagnostic sequence file 106 described above
Is created for each model of water heater. According to the rules of the above syntax, it is possible to describe a failure diagnosis sequence specific to each model. In particular, the order table that determines the order of diagnosis can be changed appropriately according to the failure rate accumulated in the past of the model, so that the optimum order of diagnosis can be given. Furthermore, it is preferable to change the order table correspondingly even when the failure rate is lowered as a result of improving the part having a high failure rate.

Returning to FIG. 9, next, the simulated remote control file 107 and the individual component drive file 10 which are the basic support functions.
8 and the maintenance monitor file 109 will be described.
FIG. 21 is an example of the simulated remote controller file 107. As shown in the screen of the simulated remote controller in FIG. 9, this file contains data for operation buttons given to the remote controller used in the target model. A read command, a command when the set value is up or on, or a down or off command is given to each button. The settable range for each button can also be given as data in the file.

The diagnostic application 100 refers to the simulated remote control file 107, displays the button given in the file on the monitor screen, and gives it to the conversion driver 110 corresponding to the operation data from the repair worker. The diagnostic application 100 is a simulated remote control file 1
The display shown in FIG. 9 is displayed on the monitor screen in accordance with the data to be displayed included in 07, and the command corresponding to the operation data is acquired from the file 107 and given to the conversion driver 110.

Therefore, by preparing the simulated remote controller file 107 according to the common format for each model of the water heater, the diagnostic application 100 can deal with it.

FIG. 22 shows an example of the individual component drive file. This file lists all the individually drivable actuator parts in the target water heater. Each part has a value that can be taken as an argument, an operation command, an end command, and the like. By referring to this file, the diagnostic application 100 displays a parts list as shown in FIG. 10 (A), and the parts selected by the repair worker are driven as individual parts as shown in FIG. 10 (B). Display the instruction screen. Then, according to the drive command selected by the repair worker, the corresponding command is converted by the conversion driver 1
Give to 10. Also in this case, the diagnostic application 100 can perform display and command transmission by creating a file in a predetermined format.

FIG. 23 is an example of a maintenance monitor file. This file includes monitor items, a command for causing the water heater to read the value to be monitored, a unit or a conversion word to be added to the data read from the water heater. For example, when the frame rod is turned on, the conversion word is 1 in the flag of the frame rod in the RAM of the water heater.
Is written and the data of the 1 is returned from the water heater side, it is used to convert the data of the 1 to on and display it on the screen. Also in this case, the diagnostic application 100 can perform display, command transmission, and monitor value reception by creating a file in a predetermined format.

As described above, the diagnostic sequence file 106 and the simulated remote controller file 10 are set for each model of the water heater.
7, the individual component drive file 108, the maintenance monitor file 109, and the like, which are created in a predetermined syntax or format in the form of a file, analysis by the common diagnostic sequence analysis means 101, display control by the diagnostic application 100, It has been understood that command transmission, sensor value reception and display, etc. can be performed. Therefore, the exchange of commands and monitor values with the water heaters below the conversion driver 110 will be described.

FIG. 24 is a diagram for explaining the exchange of commands and monitor values with the water heater. The same software modules and files as in FIG. 18 are assigned the same numbers. The conversion driver 110 created for each water heater has built-in commands and command words that can be interpreted by the target water heater (step).
1, 2) are referenced to cause the communication driver 104 to transmit the command word to the microcomputer of the water heater.

The reception and display of the monitor value is used when the sensor value is monitored. When the communication driver 104 receives the data written in the RAM area of the water heater and recognized in the microcomputer, the conversion driver 110 causes the conversion driver 110 to display the sensor in the conversion driver 110 and an arithmetic expression for conversion for display. Correspondence table file 110B
With reference to, the converted value according to the arithmetic expression is passed to the diagnostic application 100 and displayed on the monitor 105.

In the file 110C, for example, since each instruction word (step 1, 2) is often accompanied by the RAM address, the correspondence with the RAM address is stored. This file 110C is also prepared for each model of water heater. By thus separating the file 110C from the file 110A, it is possible to flexibly cope with frequent changes in the RAM address.

As described above, the diagnostic sequence file 1
06, each command of the files 107 to 109 of the basic support function such as the individual component drive file, and the conversion driver 110
Between files 110A, 110B, 110C in
By making the parts unique to the water heater common, the diagnostic sequence analysis unit 101 and the diagnostic application 110 can provide the repair worker with a display of repair support and conversation without being aware of the type of the water heater.

[0114]

As described above, according to the present invention, repair work can be efficiently performed using the same repair support device regardless of the manufacturer and model of combustion equipment such as a water heater. In addition, the additional requirements for the water heater to use the repair support device are the minimum hardware and software requirements, such as attaching a connector for communication and enabling communication with the outside. belongs to. Therefore, it is not necessary for the water heater itself to have a diagnostic function, and its cost will not be significantly increased.

Furthermore, while constantly monitoring the control state in the water heater from the portable terminal, remote control commands and individual actuators can be driven, and extremely sophisticated repair work can be performed. Then, while the repair procedure is standardized, the required functions can be made available in the form of files for each model, and frequent version upgrades can be supported.

Further, according to the present invention, since the diagnostic sequence unique to the model of the water heater or the combustion device is provided by the file created by the rule of the predetermined syntax, the optimum failure diagnostic sequence for each model. Can be provided. Moreover, it is possible to provide a common graphical user interface (GUI) to the repair workers and to provide an optimum diagnostic sequence for the target model.

Further, according to the present invention, since the parts to be monitored and the parts to be driven, which are peculiar to the model of the water heater and the combustion equipment, are given in a file of a predetermined format, the data of the file is given. According to the above, it is possible to display parts and monitor values on a common GUI.

Further, according to the present invention, since the data of the operation button of the remote controller peculiar to the model of the water heater or the combustion device is given in the file of the predetermined format,
According to the data in the file, a simulated remote control screen can be displayed on the monitor on a common GUI to enable remote control operation from the repair support device.

Further, according to the present invention, since a correspondence table for command words, RAM addresses, etc., which differ for each water heater, is prepared for each water heater, it is possible to talk on a common interface with microcomputers of different models having different diagnostic applications. You can

Moreover, according to the present invention, since a file such as a diagnostic sequence file and a file of a correspondence table of conversion driver command words are generated for each model, the consistency of commands and the like can be achieved between these files. If so, the diagnostic application common to the model can give the repair worker a common GUI and operability without recognizing the model.
