A signal of a sensor such as the switch 22 is read, a remote monitor switch is in an on state or an off state, or the burner is in a combustion state or a combustion stop state.

In the present embodiment, a password and one or more of these various commands are collected to create an interrupt operation command. The interrupt program stored in the memory 44 of the interrupt command output unit 31 uses the password.

Exhaust variation, gas type, inspection standard value, inspection target item, inspection standard and specification data such as tolerances, etc. This ID data is input by the ID data input unit 41, by keyboard key operation, or by barcode input, Or input by card input such as memory card,
The input data is read by the data reading unit 32, and this read data is added to the interrupt command output unit 31. The data output unit 33 is the interrupt command output unit 31.
Interrupt operation command added from interface 34
Via the communication cable 61 as a communication means to the combustion control unit 30 of the combustion appliance 27.

FIG. 2 shows the side of the interrupt controller 60 and the burner.
27 shows the details of the cable connection of the combustion control unit 30 side of 27. In this embodiment, a 6-core signal line is used as the communication cable, the first core signal line of these 6 cores is a ground (GND) line, and the second core line is a clock signal line. The wire of the third core is the signal line TxD for command transmission of the operation command, and the wire of the fourth core is the combustion control unit 30.
Side is a signal line RxD for responding to a command sent from the side to the interrupt control unit 60 side, and the fifth core line and the sixth core line are loop line lines passing through the mode changeover switch 35, and in this embodiment, The mode changeover switch 35 is configured by a hard switch, and by inserting a pin, the mode changeover switch 35 is turned on and the loop path is closed.

When the mode selector switch 35 is turned on, that is, when the loop path is short-circuited, the combustion control section 30 operates from the operation mode based on the operation program of the combustion control to the interrupt mode based on the interrupt operation command. It is configured to switch from the interrupt mode to the operation mode when the pin is pulled out and the loop path is opened and opened.

The external sensor 43 shown in FIG. 1 is a sensor for inspecting and correcting (calibrating) the sensor used in the combustion appliance. For example, tap water from the water heater shown in FIG. 3 (a). When the temperature sensor 15 and the flow sensor 6 are inspected, an external temperature sensor is attached to the conduit connected to the hot water supply pipe 4, and an external flow meter is connected to the conduit connected to the water supply pipe 1. It Then, the external command / driving unit 38 issues a command for detecting (reading) the hot water temperature to the external temperature sensor, which is an external sensor, and a command for reading the detected flow rate to the external flow rate sensor. These commands are performed in response to the operation command of the command output from the interrupt command output unit 31, the signal read by the operation of this external command / drive unit 38 is detected by the external response detection unit 39, and the data determination unit Added to 36.

The data determination unit 36 detects the detection signal (the detected temperature or the detected flow rate in the above example) of the external sensor 43 obtained from the external response detection unit 39 and the sensor 47 (in the above example, in the same combustion appliance 27 as the detection target). The sensor detection signals of the hot water temperature sensor and the flow rate sensor) are compared using the external sensor 43 as a reference sensor to determine whether or not the sensor 47 used in the combustion appliance 27 is normal. If the difference between the detection value of the sensor 47 used in the combustion appliance 27 and the detection value of the external sensor 43 is a difference within a predetermined allowable range, it is determined to be normal, and if it is outside the allowable range. Judge as defective. Then, when the command of the operation command requests the notification of the determination result, the determination result of the inspection target sensor is displayed on the display unit of the notification unit 40 including the liquid crystal screen and the like. Note that the notification of the notification unit 40 is not limited to screen display, and other forms of notification such as a buzzer and a lamp may be performed as necessary. The notification unit 40 is not necessarily integrated with the inspection device, and the number is not limited to one.

When the command of the interrupt operation command requests data correction, the data correction unit 37 calculates the difference between the detection value of the external sensor 43 and the detection value of the sensor 47 used in the combustion appliance 27. Then, the correction amount of the displacement of the sensor 47 of the combustion appliance with respect to the external sensor 43 is calculated and calculated, and the calculated correction value is supplied to the combustion control unit 30 on the combustion appliance 27 side via the data output unit 33. This correction value is
The data is written in the setting data memory 54 on the side of 30, and the detection value of the sensor 47 is corrected by the correction calculation unit (not shown) on the side of the combustion control unit, and the combustion operation is controlled based on the corrected sensor signal.

The combustion control unit 30 on the combustion appliance 27 side includes a data input unit 48, a main operation control unit 50, a command / drive unit 51,
It has a data output section 52, a memory clear command section 53, a setting data memory 54, and a monitor signal input / output section 55.
The data input unit 48 receives an interrupt operation command sent from the interrupt control unit 60 side through the interface 34, and adds it to the main operation control unit 50 and the setting data memory 54 in accordance with the command request.

The main operation control unit 50 has a built-in operation program for controlling the normal combustion operation of the combustion appliance 27, and controls the combustion operation according to this operation program.

A conversion table 45 is provided in the main operation controller 50.
This conversion table 45 translates and converts the command code of the interrupt operation command into the operation command signal of the actual operation of the component of the combustion appliance. For example, when the code of the command in the operation command is RD40 of the rotational speed reading command of the combustion fan, this code RD40 is translated into an actual operation command signal for detecting the rotational speed of the combustion fan. The conversion table 45 has table data (table data) indicating the relationship between the code of each command and the corresponding operation command signal for actual operation. Refer to the table data for the code of the command given as the interrupt program progresses. Then, it is immediately translated into an operation command signal for actual operation. The table data of the conversion table 45 is given as data corresponding to the address configuration of the memory to which the operation program of the main operation control unit 50 is given and the configuration of the control target element such as the actuator used in the instrument. In this case, the interrupt operation command (command) is converted into an actual operation command of a form adapted to each device. In the present specification, the operation command signal may be, for example, a command that involves driving of a component, such as a valve opening command, or a command that does not involve driving, such as a data read command. is there.

By the way, in the conventional operation program of the combustion appliance, the operation command of each step of the program is given with the address of the memory as an address. For example, the rotation start command of the combustion fan is given to the address 10 of the memory at the ignition by the igniter electrode. The command is given as an address, such as address 15 in memory. However, in the system in which the address is used as an address unit, the contents of the program are different when the device type and the like are different, so that the operation command of the same component is given to different addresses every time the device type is different. For example, the instruction to start the rotation of the combustion fan is given to address 10 in the memory for some types of equipment, while it is given to address 11 in the other types of equipment. The storage location is different, so
When an interrupt program for inspecting an instrument is to be created, there is a problem in that a different program must be created for each different instrument model or model.

In this embodiment, in order to solve such a problem, an interrupt program for outputting an operation command is created by using the operation of each element constituting the combustion appliance as a command. Therefore, according to the interrupt program for operation command output of the present embodiment, when inspecting combustion appliances and setting numerical values of control conditions, if one interrupt program is prepared, the same inspection will be performed on appliances of different models and the like. It is possible to set numerical values of control conditions, and by issuing the same command command from the interrupt control unit 60 side to the combustion control unit 30 side,
It is possible to make the response operation of the same command.

The main operation control unit 50 receives a mode switching signal from the mode switching switch 35, that is, when a pin is inserted into the hard switch shown in FIG. 2 and the mode switching switch 35 is turned on to short-circuit the loop path. Switching from the operation mode by the operation program to the interrupt mode that operates by the interrupt operation command is performed. By this mode switching, the main operation control unit 50 performs operation control according to the command request of the interrupt operation command. On the other hand, when the main operation control unit 50 is operating in the interrupt mode and a switch-off signal is added from the mode switch 35,
That is, when the pin of the hard switch is pulled out and the mode switch is turned off, the operation mode is switched from the interrupt mode to the operation mode.

The memory clear command section 53 is a setting data memory when the switch-off signal is applied from the mode changeover switch 35, that is, when the operation mode of the main operation control section is switched from the interrupt mode to the operation mode.
Output a memory clear command to 54.

The setting data memory 54 is composed of an erasable and erasable non-volatile memory such as an EEPROM, and the setting data memory 54 is operated by a data setting command of a command included in the interrupt operation command during the operation in the interrupt mode. It stores setting data that should be retained without being erased and data such as dummy temporarily stored for inspection. Then, when the memory clear command is issued from the memory clear command unit 53, the data that does not need to be stored and retained is erased.

The controlled element 56 constitutes the combustion appliance 27, for example, the solenoid valve 8 of the device shown in FIG. 3, the proportional valve 10, the capacity switching valves 11a and 11b, the water amount control valve 17, the circulation pump 20.
It means an actuator such as. When the command of the interrupt operation command commands the drive operation of the controlled element, the command / drive unit 51 drives the controlled element 56 according to the command request. For example, when the command of the operation command requests the rotation start of the combustion fan 7, the rotation start of the combustion fan 7 is performed according to this request.

The monitor signal input / output unit 55 detects the sensor to be monitored based on the monitor command of the command included in the operation command.
The detection value of 47 is read, and this read signal is supplied to the data output unit 52 or stored in the setting data memory 54 in response to a command request. The data output unit 52 transmits the monitor signal added from the monitor signal input / output unit 55 to the interrupt control unit 60 side through the communication cable 61 which is a communication means, and performs signal processing according to the command, for example, the data as described above. Data determination by the determination unit 36 and data correction by the data correction unit 37 are performed, and monitor data is displayed on the notification unit 40, for example, by displaying a message.

This embodiment is constructed as described above,
Next, an operation example using the apparatus of this embodiment will be briefly described. First, by connecting the automatic setting / inspection device 28 side and the combustion appliance 27 side with the communication cable 61, turning on the power supply of the apparatus 28 side and the combustion appliance 27 side, and turning on the mode changeover switch 35, the combustion control unit 30 switches from operating mode to interrupt mode. By advancing the interrupt program in this state, the command for each step operation of the interrupt program is added to the main operation control unit 50 of the combustion control unit 30 with the password at the head. Then, the command of the interrupt program is converted into an actual operation command signal by the conversion table 45, and the main operation control unit 50 performs the control operation according to the request of the command to perform the control target element of the combustion appliance 27.
The operating state and control conditions of 56, for example, the hot water supply temperature of the water heater is set. In this way, the operations required for the inspection and the setting of the numerical values proceed efficiently according to the interrupt program, so that the target control condition setting and the inspection operation are performed extremely efficiently in a short time.

Further, in this embodiment, the main operation control unit 50 of the combustion control unit 30 is used without using the interrupt program.
It is possible to perform operations such as numerical setting of control conditions and inspection using the operation program given to the. That is, the device of the present embodiment, by outputting the interrupt operation command from the interrupt command output unit 31, the operation according to the command of the interrupt operation command by the operation control of the main operation control unit 50 of the combustion control unit 30 side. Since it is performed, a command that performs an operation according to the operation program of the main operation control unit by an interrupt operation command and an unnecessary step operation of the operation program (step operation that is not necessary for numerical setting of control conditions or inspection) By outputting a command for canceling), the main operation control unit 50 performs operation control with an operation program in which unnecessary step operations are omitted, and the shortened operation program is used to control the target control conditions. Desired operations such as numerical setting and inspection can be performed in a short time.

Further, in the apparatus of this embodiment, it is possible to perform operations such as numerical setting and inspection of control conditions without using the interrupt program or the operation program of the main operation control section. That is, the interrupt command output unit 31
By issuing an interrupt operation command from the combustion control unit 30 to perform an operation according to the interrupt operation command, the temperature detected by the hot water outlet temperature sensor 15 of the water heater shown in FIG. If you want to monitor, by adding an interrupt operation command to the combustion control unit 30 side using the signal of the hot water temperature sensor as a command, the combustion control unit 30 side can perform the operation according to this command. The temperature detected by the hot water temperature sensor 15 is displayed on the notification unit 40, and the hot water temperature sensor can be monitored by this display. Further, when it is desired to change the valve opening amount of the water amount control valve 17, by adding a coded variable valve opening amount operation of the water amount control valve 17 to the combustion control unit 30 side as a command, the water amount control valve by the instructed amount. The valve opening amount of 17 is variable.

As described above, when the operation command of each constituent element of the combustion appliance is issued on a one-off basis, the interrupt command external input means (for example, keyboard, card, bar code, personal computer, etc.) shown in FIG. 1 is used. By inputting the encoded command using the input means) 63, this command is added to the combustion control unit 30 side, translated by the conversion table 45, and the operation according to the command can be performed.

As described above, in this embodiment, each constituent element of the combustion appliance is encoded to create a command, and the combustion control unit 30 side addresses the encoded operation command of each constituent element. Since it has a memory conversion table that converts and translates it into the command of the actual operation of each step of the sequence, even if the model or model of the combustion appliance is different, different depending on each model or model. It is not necessary to create a dedicated inspection program, and no matter what type and type of burner, a dedicated burner that is formed by a set of one or more commands that encode each component of the burner By preparing one program, it is possible to use the program to perform the same operations such as inspections without problems even with combustion appliances of different models and models. It made.

Further, since the present embodiment has the above-mentioned configuration,
It is possible to obtain an effect that a very difficult inspection can be easily performed by the manual method. For example, a freezing prevention heater, a freezing prevention temperature sensor, and a heater drive circuit that turns on the freezing prevention heater when the temperature sensor detects a heater drive start temperature (for example, 0 ° C.) are provided in the combustion instrument, and the combustion prevention is performed. When testing the heater drive circuit of the equipment in the summer, in order to manually check whether the heater drive circuit operates normally, use the dry ice etc. It must be cooled down to a driving start temperature of 0 ° C. or lower, which is very difficult. On the other hand, in the present embodiment, it is only necessary to set the interrupt mode, issue a setting write command of the detection temperature of the freeze prevention temperature sensor, and write and set the temperature to a temperature equal to or lower than the dummy heater drive start temperature. By setting this dummy temperature, the heater drive circuit determines that the freeze prevention temperature sensor has detected the heater drive start temperature and starts heater drive, and this heater drive is used to change the power consumption of the combustion appliance. It is possible to easily detect the normal state of the heater drive circuit by detecting as.

The present invention is not limited to the above-mentioned embodiments, and various embodiments can be adopted. For example, in the above embodiment, the operation of the main operation control unit on the combustion control unit 30 side is switched from the operation mode to the interrupt mode when the mode changeover switch 35 is turned on, but the mode changeover switch 35 is turned on. In addition, the operation mode may be switched to the interrupt mode when the first password of the interrupt operation command is added.

Further, in the above embodiment, the setting data memory
54 consists of non-volatile memory that can be written and erased,
Both the data to be saved and the data to be deleted later were stored in the non-volatile memory, but the setting data memory is composed of the non-volatile memory and the volatile memory such as RAM, and the non-erasing setting data is stored in the non-volatile memory. Data to be erased later is stored in a volatile memory, and unnecessary data stored in RAM is automatically erased when the power is turned off after the completion of the numerical setting operation of the control condition and the inspection operation. Good.

Further, as shown by the broken line in FIG. 1, the interrupt control unit 60 side and the combustion control unit 30 side are connected with the remote controller 57 as an intermediary, and the remote controller 57 is provided with the function of the communication cable 61. The operation mode and the interrupt mode may be switched via the communication, or communication between the control units 30 and 60 may be performed to perform operations such as setting of control conditions and inspection.

Further, in the above embodiment, the interrupt controller
Although the 60 side and the combustion control section 30 side of the combustion instrument are separated and formed as separate devices, the interrupt control section 60 may be formed in the same control device as the combustion control section 30 of the combustion instrument. In this case, the combustor has a built-in automatic setting / inspection device, and the communication cable is omitted.

Further, in the above embodiment, the operation command of the interrupt is formed by the aggregate of the password and the command, but the password is omitted and the operation command is made by one or more commands in which each component of the combustion appliance is encoded. May be configured.

As described above, according to the present invention, the command for performing the numerical setting and inspection of the burner is given by encoding each component of the burner, and therefore, even if the model or model of the burner is different. , By giving the same command, it is possible to perform the same operation command of the constituent elements according to the command. Therefore, even if the model and model of the burner are different, it is not necessary to create a dedicated program for inspection etc. individually for each model, but by giving a common interrupt program or a sporadic command, or by burning By using the operation program of the control unit, it is possible to set operation conditions such as numerical setting and inspection of control conditions of the target combustion appliance.

Further, when setting or inspecting the control conditions of the combustion appliance, it is only necessary to command necessary operations, and the operation program provided to the combustion control section of the combustion appliance is used to perform numerical setting and inspection. In this case, the unnecessary operation can be canceled and the operating program can be run, so compared to the case of running the operating program continuously from the beginning without missing parts, as in the inspection of the conventional example, The time can be shortened. Further, since the inspection can be performed by inputting the dummy information by the command command, it is possible to achieve an epoch-making effect that it is possible to easily perform the inspection which is difficult depending on human hands.
