Description

  The present invention relates to a resource supply system that supplies hot water, hot air, cold water, cold air, electric power, gas, water, and other resources to a device and a program thereof, and more particularly to processing when an abnormality occurs in a remote operation means that operates the resource supply system. It is related.

  A conventional resource supply system will be described. In a water heater that is one of the conventional resource supply systems, for example, in Patent Document 1 below, it is as follows.

  In this conventional example, as shown in FIG. 11, an appliance 34 having a hot water supply function is used as a resource supply means, and is composed of a first wireless remote controller 31, a second wireless remote controller 32, and a communication unit 33.

  The communication unit 33 is attached to the instrument 34 and is connected to the main body control unit 35 for controlling the operation of the instrument 34 in the instrument body, and storing / counting the temperature that has been used so far and the number of times each temperature is used. Has been.

  In addition, the first wireless remote controller 31 and the second wireless remote controller 32 are operated by input operation units 36 and 37 for inputting an instruction signal to the instrument 34, and an informing unit 38 for displaying the setting state, operating state, and operation content of the instrument. , 39.

  When communication is performed from the communication unit 33 toward the first wireless remote controller 31 and the second wireless remote controller 32, when there is no response to the communication, the communication unit 33 has a retry function and performs a certain number of communication retries. However, if there is no response from the wireless remote controller within a certain number of times, the communication unit 33 determines that the first wireless remote controller 31 and the second wireless remote controller 32 cannot communicate.

  At this time, the hot water supply set temperature of the appliance 34, the communication unit 33 outputs a change signal to the temperature of the preprogrammed condition to the main body control unit 35, and the main body control unit 35 that has received this signal outputs The temperature is extracted from the memory in the main body control unit 35, and the appliance 34 is controlled to change the hot water supply set temperature.

JP-A-9-159268

  However, in the conventional configuration, one wireless remote controller is in a state where communication is possible, but communication is possible when it becomes a state where the hot water supply set temperature cannot be changed. The temperature is not changed to a preprogrammed condition used when all remote controllers determine that communication is impossible.

Conventionally, a simple device such as a wireless remote controller used a one-chip microcomputer as a control means and was operated with a single task, so when the software became inoperable, all control of the remote control stopped and the hot water supply temperature When the operation is disabled, communication is normally disabled at the same time.

  However, when a system that uses a multitask OS such as LINUX (registered trademark) and operates a plurality of functions in a multitasking manner, the hot water supply operation function and the wireless communication function are configured to operate in separate tasks. Even if the operation function becomes inoperable, the wireless communication function may function, and a state where communication is possible can easily occur although the hot water supply temperature cannot be operated.

  Further, even when the hot water supply operation function is inoperable and the wireless communication function is activated, communication may not be performed correctly depending on the state of occurrence of abnormality.

  For example, even when a configuration in which “no operation” is communicated to the water heater when the hot water operation function becomes inoperable, the communication means returns a response to the communication from the water heater. It is possible, but if it is not possible to receive inoperable information from the task that detected the occurrence of an abnormality, “inoperable” cannot be transmitted.

  In such a case, the inoperable state of the hot water supply operation function cannot be transmitted to the water heater, and therefore, when only the hot water supply operation function becomes inoperable, the operation can be continued by changing to the previously stored hot water supply temperature. There was a problem that it was not possible.

  When the return button 1cbi is pressed, the GUI middle process 1af notifies the hot water supply operation process 1ah, and the hot water supply operation process 1ah notifies the GUI middle process 1ah to display the hot water supply operation screen 1ca. The middle process 1ah displays the hot water supply operation screen 1ca on the display means 1c through the OS 1aa and the display driver 1ac.

  The heat source unit 3 definitely reflects the state of the heat source unit 3 on the kitchen remote controller 1 and the bathroom remote controller 2 and confirms that communication with all remote controllers is normally performed. A message is periodically transmitted from the heat source device 3 to each remote controller.

  In the resource supply system of the present embodiment, a telegram is transmitted once a minute, and when the kitchen remote controller 1 and the bathroom remote controller 2 are correctly received, they are sent back to the heat source unit 3. If the kitchen remote controller 1 is in a different state such as bath temperature or hot water supply temperature, the kitchen remote controller 1 changes to the state of the heat source unit 3.

  In addition, when there is no reply from the kitchen remote controller 1 or the bathroom remote controller 2 in response to periodic telegram reception from the heat source unit 3, the heat source unit 3 retransmits the telegram to the remote controller without reply, If there is no reply after a certain number of retransmissions, it is determined that the remote control has been disconnected.

  In the heat source device 3, when the communication abnormality detection means 3a1 determines that all the remote controllers have been disconnected, the state change means 3a2 turns off the hot water supply operation. This is because the hot water supply temperature cannot be operated when all the remote controllers are disconnected. In such an abnormal situation, the state of the supplied resources is changed to turn off the hot water supply operation. It is possible to prevent hot water from coming out even when the karan is opened.

  Note that the hot water supply operation OFF continues until communication with one of the remote controllers is restored, and during that time, the operation remains off even if the operation is turned on from the remote controller.

  Since the kitchen remote controller 1 according to the present embodiment uses the multitask OS as described above, the necessary operations are notified only to the necessary processes, and the respective processes operate independently to realize the operations. I have to. For this reason, even if one of the processes is stopped due to a bug in the program, the processes other than the process operate normally.

  Therefore, for example, even when the hot water supply operation process 1ah is stopped, the communication management middle process 1ag operates normally.

In the resource supply system of the present embodiment, the reply to the periodic message from the heat source unit 3 is
Even if the communication driver 1ae is executing, even if the hot water supply operation process 1ah becomes abnormal and the hot water supply temperature cannot be changed, in order to normally reply to the periodic communication from the heat source unit 3, The heat source unit 3 cannot detect an abnormality. If an abnormality occurs in the bathroom remote controller 2 in this state and communication is disabled and the communication is disconnected, the heat source unit 3 may automatically turn off the operation because the kitchen remote controller 1 recognizes that it is normal. Inability to change the hot water supply temperature will continue.

  Even if the communication management middle process 1ag becomes abnormal, the operation result cannot be transmitted to the heat source unit 3 and reflected, and thus the same situation occurs.

  In order to solve this problem, the kitchen remote controller 1 of the present embodiment includes a hot water supply operation hot water supply monitoring process 1aj that operates on the OS 1aa, and monitors the GUI middle process 1af, the hot water supply operation process 1ah, and the communication management middle process 1ag. When the abnormality occurs, the communication driver 1ae is stopped.

  The abnormality monitoring of the hot water supply monitoring process 1aj is performed by periodically communicating with the three processes of the GUI middle process 1af, the hot water supply operation process 1ah, and the communication management middle process 1ag, and the received process returns a reply. Check whether or not.

  FIG. 9 shows a flowchart of monitoring process abnormality.

  (1) When abnormality monitoring is started (20a), first, a message is transmitted to the designated process (20b), and it is confirmed whether there is a reply within a certain time (20c).

  (2) If a reply is received within a certain time, the designated process busy count is cleared (20d) as normal, but if there is no reply within a certain time, the number of no reply is counted (20e). If it is less than the predetermined value, the message transmission (20b) is performed again to the designated process.

  (3) If the count value is equal to or greater than the predetermined value, the result is busy, the busy count is performed (20 g), and the busy count is compared with the predetermined value (20 h).

  (4) If the busy count is equal to or greater than the predetermined value, it is determined that the designated process is abnormal (20i), and the process ends. If it is equal to or less than the predetermined value, the process ends.

  The designated processes in FIG. 9 are a GUI middle process 1ag, a hot water supply operation process 1ah, and a communication management middle process 1ak, which are separately retransmitted and counted as busy. For example, the hot water supply monitoring process 1aj performs the processing shown in FIG. 9 for the above three processes at intervals of 10 minutes, and counts the number of busy times as busy if there is no response three times in succession, and continues three times. And when the busy count reaches 3, the process is determined to be abnormal.

  Also, if there is a reply after busy, the busy count is cleared, and it is determined that there is an abnormality only when the abnormality continues for a long time. Thereby, it can be prevented from detecting an abnormality due to a temporary abnormality. The no-reply count is cleared before this process is started.

  When the hot water supply monitoring process 1aj detects an abnormality as described above, the hot water supply monitoring process 1aj sends a communication function OFF notification to the communication driver 1ae so that the communication driver 1ae does not reply to the message received from the heat source unit. To do.

  Normally, the communication driver 1ae transmits a reply message predetermined to the message received from the heat source unit 3 to the heat source unit 3, and the heat source unit 3 receives this reply message and recognizes that the kitchen remote control exists. To do.

  On the other hand, when the communication driver 1ae receives the notification of the communication function OFF from the hot water supply monitoring process 1aj, the communication driver 1ae is configured not to reply to the message received from the heat source unit 3.

  As a result, no reply is sent to the periodic communication from the heat source unit 3, so that the heat source unit 3 recognizes that the kitchen remote controller has been disconnected due to communication abnormality detection means 3a1 and has been disconnected. can do.

  With the above configuration, when an abnormality occurs in the GUI middle process 1ag and the screen, touch panel, hard buttons, etc. cannot be operated, an abnormality occurs in the hot water supply function process 1ah, and the kitchen remote control 1 can operate the hot water supply function. If the communication management middle process 1ag is lost or if an abnormality occurs in the communication management middle process 1ag and the content of the hot water supply operation is not transmitted to the heat source unit 3, the communication driver 1ae is set to the communication function OFF and the periodic message transmission from the heat source unit 3 is not returned Therefore, it can be determined that the heat source device 3 cannot communicate with the kitchen remote controller 1 and is not connected.

  Accordingly, if the bathroom remote controller 2 is also unable to communicate and is disconnected at the same time, the communication abnormality detecting means 3a1 detects that both the kitchen remote controller 1 and the bathroom remote controller 2 have communication abnormality in the heat source unit 3, and the state changing means 3a2 can change the state so that hot water is not discharged from the currant, and the state can be changed reliably.

  Furthermore, the resource supply system of the present embodiment has an overall monitoring process 1ak, and monitors the GUI middle process 1af, the communication management middle process 1ag, the hot water supply operation process 1ah, the bath operation process 1ai, and the hot water supply monitoring process 1aj.

  Regarding the point of monitoring the hot water supply monitoring process 1aj, when the hot water supply monitoring process 1aj itself becomes abnormal, the hot water supply temperature cannot be changed as described above, but it cannot be detected even if communication is possible. However, this is particularly important because the overall monitoring process 1ak can detect and deal with this by monitoring the hot water supply monitoring process 1aj.

  The overall monitoring process 1ak uses the process list display function provided by the OS 1aa, and by inputting a predetermined command to the OS 1aa, it is possible to acquire a list of processes currently activated from the OS 1aa.

  Among the acquired processes, if all the processes to be monitored exist, the process is normal, and if any process does not exist, it is detected as abnormal.

  When the overall monitoring process 1ak detects an abnormality, first, an abnormality as shown in FIG. 10 is notified on the display means, and an abnormality notification screen 1cc on which a countermeasure is described is displayed. The user of this system sees this display, inserts a thin stick such as a toothpick from the round hole 1fa on the right side surface of the main body case 1f, presses the reset switch, and restarts the system.

  As a result, the user can be notified of the abnormality and can be restarted by the reset button, and can be restarted after the software and hardware are initialized to return to the normal state.

  Further, when the hot water supply monitoring process 1aj is abnormal, the overall monitoring process 1ak stops the function of the communication driver 1ae when the abnormality is detected. As a result, even if it takes a long time for the user to notice the screen shown in FIG. 10 and to return to normal by pressing the reset button after the occurrence of abnormality, the overall monitoring process 1ak immediately detects the heat source after detecting the abnormality. Communication to the machine 3 can be cut off.

  In the resource supply system of the above embodiment, the GUI middle process 1ag, the hot water supply function process 1ah, and the communication management middle process 1ag are monitored, but in addition to this, the display driver 1ac may be monitored. Good. When the display driver 1ac becomes abnormal, it is not possible to display the screen on the display means 1c, which is effective in preventing the hot water from being used without knowing the current hot water supply temperature.

  Further, in the resource supply system of the above embodiment, the heat source unit becomes unable to communicate with all remote controllers and turns off the hot water supply operation when it is determined that it has been disconnected. The configuration may be such that the temperature is forcibly changed to a predetermined temperature.

  In the resource supply system of the above embodiment, when the communication driver 1ae receives a notification that the communication function is OFF, the reply to the message received from the heat source device 3 is not performed. I do not refuse to send to.

  This is because when an abnormality such as a hot water supply operation process or the like occurs, a message is not basically transmitted to the heat source device, so there is no need to reject it. However, it is not possible to know what kind of abnormality occurs, and there may be an abnormality that continues to transmit a message. Therefore, in consideration of this, a configuration may be adopted in which neither transmission nor transmission is performed.

  Further, in the resource supply system of the above embodiment, when the communication driver 1ae receives the notification of the communication function OFF, the reply to the message received from the heat source unit is not performed, but the hot water supply monitoring process 1aj is detected after abnormality is detected. Also, a configuration may be adopted in which the communication function of the communication driver 1ae is turned on and communication can be performed again when it is detected that the hot water supply monitoring process 1aj has returned to normal by operating continuously.

  In this case, it is also possible to adopt a configuration in which an abnormality is confirmed by one time instead of setting the number of busy times, and the abnormality monitoring detection level of the monitoring process is lowered to detect even a slight abnormality as an abnormality.

  Conversely, when it is determined that the hot water supply monitoring process 1aj is abnormal, the communication driver 1ae alone or both the communication driver 1ae and the communication management middle process 1ah may be deleted. Since the abnormality detected by the hot water supply monitoring process 1aj is a content that cannot be normally performed, the communication to the heat source unit 3 can be more reliably cut off.

  Further, since the overall monitoring process monitors the communication management middle process 1ah and detects that the communication management middle process 1ah has been deleted, the process for restarting the remote control means is executed. When an abnormality occurs, it can be restored to a normal state by restarting.

In the resource supply system of the present embodiment, the overall monitoring process 1ak immediately stops the function of the communication driver 1ae only when the hot water supply monitoring process 1aj is abnormal. However, the other processes are abnormal. Alternatively, the communication driver 1ae may immediately stop functioning. As a result, even if other processes are abnormal, the heat source device can detect the abnormality of the remote controller at an early stage due to communication interruption.

  The resource supply system according to the present embodiment displays an abnormality notification screen 1cc on the display means when the overall monitoring process 1ak detects an abnormality, and prompts the user to perform an operation for restarting. It may be configured to restart immediately when it is detected. However, in this case, the user may not be able to recognize that an abnormality has occurred, and it is desirable to have a configuration in which a warning is displayed and the user is allowed to perform a restart operation when notifying the occurrence of the abnormality.

  In addition, the resource supply system of the present embodiment is described by taking the kitchen remote controller of the gas hot water supply system as an example, but the terminal device is used in a system that supplies electricity, hot water, gas, water, etc. in the home or office. Any system that can be operated remotely can be applied.

  The resource supply system described in the above embodiment constitutes operation means for operating the terminal device from the information terminal in a system that supplies and uses not only hot water but also resources such as electric power, gas, and hydropower to the terminal device. It is possible to provide an easy-to-use resource supply system.

  Note that the means described in this embodiment causes hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electrical / information device including an I / O, a computer, a server, and the like to cooperate. You may implement with the form of a program. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media or distributing them via a communication line such as the Internet.

  As described above, the resource supply system and the program thereof according to the present invention can reliably change the state of the resource supply means even when the operation function of the remote control means for controlling the resource supply means is disabled. Further, the present invention is not limited to a hot water supply / heating system using hot water, but can also be used in a system that supplies and uses resources such as electric power, gas, hydraulic power, and petroleum fuel to terminal equipment.
