When the inspection of the control part has been completed, the inspection uncompleted data stored in the non-volatile storage means is replaced with the inspection completed data.

Description

  The present invention relates to a control apparatus, and more particularly to an electronic apparatus control apparatus having an inspection mode.

  In a control device that controls an electronic device, inspection such as operation check is often performed before the electronic device is supplied to the market. This type of control device is required to be able to independently execute a normal mode for controlling the operation of the electronic device so that the user can use the electronic device and an inspection mode for inspecting the control device itself.

  For example, in Patent Document 1, in a control device of a sanitary washing device, when a power switch is turned on, a forced switch input such as turning on the power while simultaneously pressing a plurality of preset operation switches is performed. The mode (forced switch acceptance mode) is started. When there is no forced switch input, the normal mode (normal operation mode) is executed.

JP-A-6-136806

  In the control device that requires a special input to execute the inspection mode, such as the forced switch input in Patent Document 1, the normal mode is automatically executed unless a special input is made, so the inspection mode is executed. If an electronic device having a control device that has not been supplied is supplied to the market, when the general user turns on the power, the normal mode is executed without executing the inspection mode. Then, if there is an abnormality or failure in this control device, it will hinder the use of electronic devices by general users.

  A problem to be solved by the present invention is to provide a control device for controlling an electronic device, in which a control device that has not been inspected is prevented from flowing into the market and being used by a general user. There is.

  In order to solve the above problems, a control device according to the present invention includes a control unit capable of controlling an electronic device, and the control unit determines whether or not the control unit has been inspected. Non-volatile storage means capable of storing inspection incomplete data indicating that the inspection of the control unit is not completed and inspection completion data indicating that the inspection of the control unit is completed, and the control unit Data rewriting means for rewriting the inspection incomplete data stored in the non-volatile storage means to the inspection completion data when the inspection is completed, and power on detection means for detecting that the control section is powered on And a mode selection means capable of selectively executing a normal mode for executing control for operating the electronic device and an inspection mode for executing inspection of the control unit, and turning on the power If the inspection incomplete data is stored in the nonvolatile storage means when the output means detects power-on, the mode selection means executes the inspection mode, and the inspection completion data is stored in the nonvolatile storage means. When stored in the storage means, when the mode selection means executes the normal mode and the inspection of the control unit is completed, the data rewriting means is stored in the nonvolatile storage means. The gist is to replace incomplete data with the inspection completion data.

  Here, it is preferable that the control unit is a microcomputer, and the nonvolatile storage means is a nonvolatile recording medium built in the microcomputer.

  Further, it is preferable that the inspection completion data can be replaced with the inspection incomplete data.

  And it is preferable that the said control apparatus further has a notification part which can notify outside the distinction whether the said test incomplete data is memorize | stored in the said non-volatile memory | storage means, or the said test completion data is memorize | stored.

  At this time, the notification unit includes a flashable light emitting means, and the fact that the inspection incomplete data is stored in the nonvolatile storage means is notified to the outside by the flashing of the light emitting means, The fact that the inspection completion data is stored in the nonvolatile storage means may be notified to the outside by not lighting the light emitting means.

  The control device is preferably provided in a sanitary washing device.

  In the control device according to the invention, the inspection mode is automatically executed only by turning on the power in a state where the inspection of the control unit is not completed. Thereby, it is prevented that the control apparatus which does not pass through an inspection leaks to the market and is used for general users.

  In addition, in order to execute the inspection mode, it is not necessary to perform a special input, the process for the inspection of the control device is simplified, and equipment such as a device for performing a special input is not necessary, Costs required for inspection are suppressed.

  Here, if the control unit is a microcomputer and the nonvolatile storage means is a nonvolatile recording medium built in the microcomputer, the entire control device is miniaturized, and the control device can be installed in a limited space. Can be arranged.

  In addition, when the inspection completion data can be replaced with the inspection incomplete data, even after the inspection is once completed and the inspection completion data is stored, the inspection completion data is rewritten to the inspection incomplete data so that the control is performed once. The inspection of the control unit can be performed again on the apparatus. If such a thing is possible, it can respond to the request | requirement of inspection re-execution etc., and it can expect further certainty in the test | inspection of a control part.

  And when the said control apparatus further has a notification part which can notify the distinction whether the said test incomplete data is memorize | stored in the said non-volatile memory | storage means, or the said test completion data is memorize | stored, The manufacturer and user can clearly recognize whether the inspection is completed.

  At this time, the notification unit includes a flashable light emitting means, and the fact that the inspection incomplete data is stored in the nonvolatile storage means is notified to the outside by the flashing of the light emitting means, The fact that the inspection completion data is stored in the non-volatile storage means is notified to the outside when the light emitting means is not turned on, and if the inspection of the control unit is not completed, the power is turned on. By flashing the light emitting means when the battery is inserted, it is possible to make the manufacturer strongly recognize that the inspection has not been performed. In addition, even if a control device in which inspection incomplete data is stored leaks to the market, the user can be alerted. On the other hand, when the inspection is completed, the light emitting means is not turned on, so that the user does not have anxiety that there is an abnormality in the control device or the electronic device, and uses the control device and the electronic device with peace of mind. Can do.

  In addition, when the control device is provided in a sanitary washing device, in view of the properties of the sanitary washing device in which components and hot water are in direct contact with the human body, burns or electric shocks resulting from abnormalities or failures in the control device Serious accidents such as occurrence can be effectively prevented.

It is a block diagram which shows the structure of the control apparatus concerning one Embodiment of this invention. It is a flowchart which shows operation | movement of the said control apparatus.

  Hereinafter, a control device according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a control device 1 according to an embodiment of the present invention. The control device 1 includes a control unit 10 that controls an electronic device (not shown).

  The control unit 10 includes mode selection means 11, power-on detection means 12, inspection status determination means 13, data rewrite means 14, nonvolatile storage means 15, inspection mode execution means 16, and normal mode execution means 17. Specifically, the control unit 10 is implemented by a microcomputer or the like.

  The control unit 10 includes a normal mode in which the electronic device is controlled when the user uses the electronic device in a normal method, and an inspection mode in which the manufacturer inspects whether the control unit 10 itself has any abnormality or failure. Have. Only one of these modes can be executed simultaneously. The mode selection means 11 has a function of selecting and executing either the normal mode or the inspection mode.

  The power-on detection unit 12 can detect that the control device 1 including the control unit 10 is powered on, for example, by connecting a power plug to a commercial power source. When the power-on detection unit 12 detects power-on, a signal indicating detection of power-on is transmitted to the mode selection unit 11.

  The inspection status determination unit 13 detects the status of the inspection performed on the control unit 10 and determines whether the inspection has already been completed or not. Then, the determination result is output to the data rewriting means 14.

  The data rewriting unit 14 rewrites between the inspection completion data and the inspection incomplete data stored in the nonvolatile storage unit 15 in accordance with the inspection execution state of the control unit 10 transmitted from the inspection state determination unit 13. .

The nonvolatile storage means 15 includes “inspection completion data” indicating that the inspection of the control unit 10 in the inspection mode is completed and “inspection incomplete data” indicating that the inspection of the control unit 10 is not completed. Can be remembered. Only one of these two data is stored in the control unit 10 at the same time and can be rewritten mutually. The non-volatile storage means 15 is preferably implemented by a non-volatile recording medium such as E ² PROM, and is preferably built in the control unit 10 embodied by a microcomputer from the viewpoint of miniaturization of the entire control device 1. In the state immediately after the manufacture of the control unit 10, the inspection incomplete data is written in the nonvolatile storage means 15.

  When the inspection mode is executed in a state where the inspection incomplete data is stored in the nonvolatile storage means 15 and a signal indicating that is input from the inspection status determination means 13 to the data rewriting means 14, the data rewriting means 14 Replaces the inspection incomplete data stored in the nonvolatile storage means 15 with the inspection completion data. On the other hand, when the control device 1 has a special input unit 30 to be described later, input from the special input unit 30 to the data rewriting unit 14 is performed in a state where the inspection completion data is stored in the nonvolatile storage unit 15. Then, the data rewriting unit 14 replaces the inspection completion data stored in the nonvolatile storage unit 15 with the inspection incomplete data.

  When the mode selection unit 11 selects an inspection mode, the inspection mode execution unit 16 receives a signal input from the mode selection unit 11 and actually executes the inspection mode. The specific content of the inspection for the control unit 10 is set according to the control content by the control device 1 and the function of the electronic device controlled by the control device 1, but the electronic component mounted on the electronic board For example, it is confirmed whether there is any abnormality or failure in the components of the control unit 10. For example, when the inspection mode is executed, it is possible to exemplify a form in which inspection such as performing a certain input to the control unit 10 and confirming a response output thereto is automatically performed in the control unit 10. If any abnormality or failure is found in the control unit 10 in the course of this inspection, the inspection mode execution means 16 may make the worker recognize by performing an output indicating that, depending on the nature of the abnormality. Calibration, etc. may be performed automatically. Alternatively, it is not necessary that all necessary parts are automatically inspected by executing the inspection mode. For example, when the mode selection means 11 selects the inspection mode, the inspection mode execution means 16 makes it possible for an operator to attach an inspection tester to the electronic board of the control unit 10, or allows the operator to remove the electronic board. Then, it is possible to adopt an embodiment in which the operator actually inspects each electronic component by attaching the tester or removing the electronic board. In this case, the situation in which the inspection status determination means 13 determines that the inspection of the control unit 10 is completed is not simply that the inspection mode is executed, but in the inspection mode, the tester is attached or the board is This refers to a situation in which all inspections of the control unit 10 involving removal are completed.

  When the mode selection unit 11 selects the normal mode, the normal mode execution unit 17 receives a signal input from the mode selection unit 11 and actually executes the normal mode.

  The control device 1 can include a notification unit 20 together with the control unit 10. The notification unit 20 receives an input from the inspection status determination unit 13 of the control unit 10, and the nonvolatile storage unit 15 stores it when the power-on detection unit 12 transmits the power-on detection to the mode selection unit 11. Is notified to the outside of the control device 1 in a form that can be recognized by a human being. As a specific configuration of the notification unit 20, a light emitting unit such as an LED lamp can be exemplified.

  In this case, it is preferable that the light emitting unit is not turned on when the inspection completion data is stored in the nonvolatile storage unit 15 and the light emitting unit blinks when the inspection incomplete data is stored. If inspection completion data is stored and the configuration is such that the light emitting means is lit (flashing), the user uses the control device 1 that has been confirmed by the control unit 10 to be normal. Therefore, at the moment when the power is turned on, the light-emitting means is turned on (flashes), and there is a high possibility that the user may be suspected or anxious about some abnormality. On the other hand, as described above, when the inspection has been completed, if the light emitting unit is not turned on, the user can use the control device 1 and the electronic device with the inspection completed with peace of mind. In addition, when the inspection is not completed, the light emitting means blinks, so that attention can be drawn, so that the manufacturer can supply (for example, not the inspection specialized for the control unit 10) before supplying to the market. ) When the power is turned on for the operation inspection of the entire electronic device, the manufacturer can recognize with a strong impression that the control unit 10 has not been inspected. Furthermore, even if the control device 1 that has not inspected the control unit 10 leaks to the market, the user can be encouraged to take measures such as reporting to the manufacturer.

  It is preferable that the control device 1 further includes a special input unit 30. When a signal is input from the special input unit 30 to the data rewriting unit 14 in a state where the inspection completion data is stored in the nonvolatile storage unit 15, the data rewriting unit 14 stores the inspection completion data in the nonvolatile storage unit 15. Replace with incomplete inspection data. Normally, once the inspection of the control unit 10 is completed and the inspection completion data is written in the nonvolatile storage means 15 by the data rewriting means 14, the fact that the inspection has already been completed does not change, so the inspection completion data is inspected. It is not replaced with incomplete data. However, once the inspection is completed, if it is necessary for the manufacturer to re-inspect the control unit 10 due to incomplete inspection or more detailed inspection, the data from the special input unit 30 By inputting a signal to the rewriting unit 14, the data stored in the nonvolatile storage unit 15 can be rewritten to uninspected data. Then, when the power is turned on next time, the mode selection unit 11 selects the inspection mode, the notification unit 20 displays that the inspection is not completed, and the control unit 10 can be inspected again. It becomes.

  In view of such a function of the special input unit 30, it is not preferable that a general user can easily operate the special input unit 30 to input a signal to the data rewriting unit 14. Specifically, for example, a signal input switch is provided at a location that cannot be easily operated by a general user, such as an electronic board constituting the control unit 10, so that signal input cannot be performed unless complicated operations are performed. For example, the special input unit 30 may be configured.

  Next, the operation of the control device 1 will be described based on the flowchart of FIG.

  In the initial state, the power supply to the control unit 10 is cut off. In step S0, the control unit 10 is powered on, for example, by connecting a power plug to a commercial power source. Then, the power-on detection unit 12 detects the power-on and outputs a signal indicating that to the mode selection unit 11.

  The mode selection unit 11 that has received the signal input from the power-on detection unit 12 refers to the inspection status stored in the non-volatile storage unit 15 in step S1, and checks whether the inspection completion data is stored or not. Determine whether it is stored.

  If inspection incomplete data is stored (in the case of “No” in step S1), the mode selection unit 11 selects execution of the inspection mode in step S2, and the inspection mode execution unit 16 sets the inspection mode. Let it run. In addition, the notification unit 20 that has received the input from the inspection status determination unit 13 notifies that the inspection has not been completed.

  In step S3, the inspection status determination unit 13 determines whether the inspection of the control unit 10 has been completed. If the inspection of the control unit 10 is not completed (“No” in step S3), the inspection mode execution means 16 continues to execute the inspection mode of step S2. The notification unit 20 continues to notify that the inspection is incomplete.

  On the other hand, if the inspection status determination means 13 determines in step S3 that the inspection of the control unit 10 has been completed (if “Yes” in step S3), the process proceeds to step S4, and the signal from the inspection status determination means 13 The data rewriting means 14 that has received the input rewrites the inspection incomplete data stored in the nonvolatile storage means 15 to inspection completion data. In addition, the notification unit 20 that has received the input from the inspection status determination unit 13 notifies that the inspection has been completed.

  Thereafter, the control device 1 stands by in a state until the power supply to the control unit 10 is interrupted by unplugging the power plug or the like. That is, neither the inspection mode nor the normal mode is executed. The notification means 20 remains in a state where a notification indicating that the inspection has been completed is performed.

  On the other hand, when the test completion data is stored in the nonvolatile storage means 15 referred to by the mode selection means 11 in step S1 (in the case of “Yes” in step S1), the mode selection means 11 in step S6. Selects execution of the normal mode, and causes the normal mode execution means 17 to execute the operation of the control unit 10 in the normal mode. In addition, the notification unit 20 that has received the input from the inspection status determination unit 13 notifies that the inspection has been completed.

  Here, in step S7, unless the input for rewriting data from the special input unit 30 is performed (as long as “No” in step S7), the execution of the normal mode in step S6 is continued.

  On the other hand, when the data rewriting means 14 is instructed to the data rewriting means 14 by the special input means 30 in step S7 while the normal mode is being executed in step S6 (if “Yes” in step S7), the data rewriting means. 14 rewrites the inspection completion data stored in the nonvolatile storage means 15 to the inspection incomplete data. Thereafter, the process proceeds to step S6, and the normal mode is executed again.

  Since the inspection incomplete data is stored in the non-volatile storage means 15 of the control unit 10 immediately after manufacture, when the manufacturer first turns on the power to the control unit 10 to perform the inspection of the control unit 10, S1 → Each step is executed in the order of S2-> S3-> S2-> S3-> ...-> S2-> S3-> S4-> S5. After step S5, the manufacturer shuts off the power supply to the control unit 10, supplies the control unit 10 to the market, and when the user who purchased it turns on the power to the control unit 10, the inspection is already performed by the manufacturer. , The steps S1 → S6 → S7 → S6 → S7 →... Are executed, and the user can start using the control device 1 and the electronic device controlled thereby in the normal mode. . The same applies when the user once cuts off the power supply and then turns on the power again. Since the normal mode cannot be executed for the control device 1 that has not been inspected by the control unit 10, the user should use only the control device 1 that has been inspected by the control unit 10 in the normal mode. Is guaranteed.

  On the other hand, when the manufacturer once completes the inspection and wants to perform re-inspection on the control unit 10 that has cut off the power supply, when the power is turned on again, each of S1 → S6 → S7 → S6 → S7. Since the steps are executed, if the special input unit 30 performs input there, steps S7 → S8 → S6 → S7 →... Are executed. Here, once the power supply to the control unit 10 is interrupted and the power is turned on again, the steps are executed in the order of S1, S2, S3, S2, S3,..., S2, S3, S4, and S5. It can be performed.

  In addition, after confirming that the manufacturer has no abnormality or failure in the control unit 10 by executing the inspection mode, an inspection (product inspection) for confirming the operation of the control device 1 and the entire electronic device controlled by the controller 1 is performed. When performing, it may carry out following the said step S5. In addition, when a product inspection is performed on the control device 1 in which the inspection mode specialized for the inspection of the control unit 10 is not executed, when the power is turned on for the product inspection, Steps S 1 → S 2 → S 3 → S 2 → S 3 →... → S 2 → S 3 → S 4 → S 5 are executed, and an inspection mode specialized for the inspection of the control unit 10 is executed.

  The control device 1 having the above configuration can be applied to any electronic device that requires the inspection mode and the normal mode, but is suitable for a sanitary washing device typified by a warm water washing toilet seat. Can be applied. In the sanitary washing apparatus, components and warm water are in direct contact with the human body, but when the control unit 10 is turned on as described above, it is automatically determined and notified whether the inspection of the control unit 10 is completed, Since the inspection mode is executed, it is possible to effectively prevent a serious accident such as an electric shock or a burn caused by a malfunction of the control unit 10.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said Example at all, A various change is possible in the range which does not deviate from the summary of this invention.
