Abstract

PURPOSE:To promote a user to cancel the reset caused by the abnormal state of an equipment after the safety of the equipment is confirmed and to improve safety by canceling the reset only with a main power supply switch for the equipment of a centralized control system. CONSTITUTION:In a main body 1 of the equipment, a control part 2 judges by an operation discriminating means 11 whether a signal inputted by an operation switch 3 in the main body 1 of the equipment or an HA control switch 5 in an HA control part device is to be turned to an operating state or a stop state. Then, a judged result is outputted as an operation instructing signal to an equipment driving means 12. When the operation instructing signal is inputted, the equipment driving mean 12 displays control information in a display warning means 7 and sends out a signal to a drive load group 8 so that the equipment can be driven and stopped. When an abnormal mode signal is inputted from an abnormality detecting means 6, an abnormality processing means 13 output reset signal to the equipment driving means 12 so that the equipment can be turned to reset state. During the reset caused by the abnormal state of the equipment, such a state can not be canceled by operation from the operation switch 3 and HA control switch 5 but it can be canceled only by a main power supply switch 10.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an operation control device for equipment that instructs cancellation of an abnormal operation stop (hereinafter referred to as "reset") state in an HA control equipment. BACKGROUND TECHNOLOGY In general, as shown in Fig. 3, a so-called centralized control system has been introduced in which devices are home automated and the operation of a plurality of devices 1a-1x is instructed from a single control device 4. There are devices (hereinafter referred to as HAMJ devices). In the case of this device, as shown in FIG. 4, in addition to the operation switch 3 installed on the device 1a, there is also an operation switch 5 (hereinafter referred to as HA control door switch) installed on the HA control device 4. In addition to the operation switch 3 and the HA control switch 5, there is a main power switch IO that cuts off the power supplied to the equipment 1a to improve safety. Some main power switches 10 cut off only the load on the device 1a while leaving the power supplied to the control unit 2 as is, but when the main power switch IO is in the OFF state due to the operation of the control unit 2, the operation switch 3 Or, no matter which one of the HA control switches 5 inputs the operation instruction signal, the operation state will not be established and the load will remain stopped. Also, main power switch 1
0 is in the ON state, when a repeat operation instruction signal is input to the control unit 2 from either the operation switch 3 or the HA control switch 5, the control unit 2 outputs the device lh -ne signal. Then, when the operation instruction signal is input again to the control section 2 from either the operation switch 3 or the HA control switch 5 while the device 1a is operating, the control section 2
outputs a load stop signal to the drive load group 8 according to a preset sequence in order to stop the operation of the device 1a.

In this way, when the main power switch 10 is in the ON state, the operation switch 3 and the HA control switch 5 similarly send an output signal to the control section 2, thereby controlling the device 1a.
It is possible to instruct the start or stop of operation of the main power switch 10 or the operation switch 3 and the HAIH1m switch 5 to switch whether or not to permit input of operation instruction signals. Also, if the device becomes abnormal during operation, or if the device 1a
When the motor enters an abnormal state while stopped and then starts operation, the abnormal state is detected by the abnormality detecting means 6 and an abnormal mode signal is output to the control section 2. When the control unit 2 receives an abnormal mode signal, it issues an operation stoppage signal 1! in an abnormal mode in order to safely stop the device 1a. (Reset punch line)
In order to do this, a load drive signal and a load stop signal are output to the drive load group 8 according to a preset sequence. In addition, when the reset is in progress and the abnormal mode signal is output from the abnormality detection means 6, that is, when the abnormal state has not been canceled, the operation instruction signal from the operation switch 3 or the HA control switch 5 is controlled. Even if an input is made to section 2, the reset mode will not be canceled and the state will not change to the operating state. However, even during a reset, if the abnormal state is naturally canceled and the abnormal mode signal is no longer output from the abnormality detection means 6, the operation instruction signal from the operation switch 3 or the HA control switch 5 will be sent to the control unit 2. is input, the reset punchline is automatically canceled and device 1 is
a is in normal operating condition. The problem that the invention seeks to solve
IR However, in order to cancel an abnormal state during a reset in such a device, it is necessary for the user to take some action on the device itself or to wait for the abnormal state to be released naturally. There is. In order to do this, you must be in front of the device itself, and even if it is in the process of being reset, if the abnormal condition is cleared naturally, HAIII
If you cancel the reset punch with the control switch 5 signal, the signal will be input without knowing what kind of abnormal state the equipment is in, and it will be unclear whether the equipment has resumed normal operation or not, resulting in an emergency situation. It is dangerous. In addition, the operation switch 3 and the HA control switch 5 output pulse signals to perform operation.
Since this is an instruction to stop, if the HAIII control switch device 4 is connected via a cable or the like from a remote location, there is a risk that the pulse signal may malfunction due to the influence of noise, etc. Even during a reset, if the abnormal state is naturally released, there is a risk that the reset may be canceled due to a malfunction of this pulse signal. The present invention has been made in view of these points, and its primary purpose is to ensure safety by allowing the reset punch to be canceled only with the main power switch. In addition, with this kind of precaution, if the power input to the device is temporarily interrupted and then restored after the abnormal condition is canceled while the device is running or during a reset, the abnormality detection means will Since the abnormal mode signal has not been input to the control unit, the reset state is canceled and the machine enters the standby state. If the system is in standby mode, operation can also be started using the operation switch or HA control switch. Therefore, the second objective is to further improve safety by creating a structure in which the reset button is not released even if a power outage occurs, and a structure in which the device is kept in memory while it is running. Means for Solving the Problems In order to achieve the above object, the operation control device of the present invention is installed in a device to control the operation of a device that uses a centralized control system in which multiple devices are instructed to operate from a local control device. an operation switch that instructs ON or OFF; an HA control device that is located in a remote location and instructs operation from the one control device;
An IC switch installed in the HA control device that instructs ON or OFF operation, a power supply unit that supplies power to equipment, and a main unit that cuts off the source that supplies power to the load of one equipment from the source unit. A power switch, an abnormality detection means for detecting an abnormality in the equipment, an abnormality handling means for instructing the equipment to be reset using the abnormality detection means, and an operation switch and an HA control switch for determining whether to turn the operating state ON or OFF. comprising an operation determining means for determining the operation, and an equipment driving means for instructing the operation state, the operation standby state, or the reset state processing according to instructions from the operation determining means and the abnormality processing means,
Moreover, the above-mentioned reset state is designed to be released only by operating the main power switch. In addition, in order to memorize the reset information during a power outage and retain the information that the device is running, the power outage abnormality process determines that a power outage occurred while the device was running and instructs the device drive means to reset the power outage. It is a precept with a means. Effect of the Invention With the above-mentioned structure, the present invention can prompt the user to cancel the reset after confirming the safety of the equipment when the equipment is in an abnormal state, and can also be reset automatically by an erroneous signal from the operation switch or the HA control switch. It also prevents the driver from starting driving after releasing the punchline, improving safety. Further, even after the power is restored, the above effect can be achieved by maintaining the reset state. Embodiments Hereinafter, embodiments of the present invention will be explained based on the accompanying drawings.
Figure 1 is a diagram of the configuration of equipment driven by a control device installed in the HA centralized control system, where 1 is the main body of the equipment, 2
3 is a control unit of the equipment, 3 is an operation switch using a tact switch that instructs the operation of the equipment, 4 is an IAII111 device for operating the equipment from a location other than the zero body 1, and 5
is a HAIII control switch, 6 is an abnormality detection means for detecting an abnormal state of the equipment, 7 is a display/alarm means for displaying the operating status of the equipment or emitting an alarm sound, 8 is a drive load group for driving the equipment, and 9 is a drive load group for driving the equipment. The power supply section IO for supplying power to the devices is a main power switch that switches whether or not to supply power from the power supply section 9 to the drive load group 8 .

When an operation signal is input to the control unit 2 using the operation switch 3 or the HA control switch 5 to drive the equipment,
The drive load group 8 is driven according to the control means set in advance by the control section 2, and the display/alarm means 7 is caused to display control information. When the operation signal is again input to the control unit 2 using the operation switch 3 or the HA control switch 5, the drive load group 8 is stopped according to the control procedure set in advance by the control unit 2, and the display alarm means 7 indicates that it is in a stopped state. Display the control information for. Further, when the equipment becomes abnormal and an abnormal mode signal is input from the abnormality detection means 6, the drive load group 8 is driven and stopped according to a preset control procedure to reset the equipment, and the display alarm means Display the control information on 7. The control unit 2 has a structure in which a signal input from the operation switch 3 or the HA control switch 5 is used to determine the operation in 11 stages.
The device driving means 12 determines whether to put it into an operating state or a stopped state, and uses the result as an operation instruction signal.
Output to . In the device drive 1,000-stage l2, when the operation instruction signal from the operation determination means 1l is input, the display alarm means 7
The control information is displayed on the drive load group 8, and a signal is sent to drive and stop the drive load group 8. When the abnormality mode signal from the abnormality detection means 6 is inputted to the abnormality processing means 13, a reset signal is outputted to the equipment driving means 12 to bring the equipment into the reset state. The power outage abnormality processing means 14 checks the information of the main power switch 1O when the input from the power supply section 9 disappears and then receives the input again, and if the main power switch 10 is in the ON state, it is assumed that there has been a power outage. A reset signal is output to the device driving means 12.
In addition, if it is in the OFF state, it is considered normal, and the device driving means 1
Outputs a normal signal to 3. If the reset punch signal is input to the device driving means 12, the display alarm means 7
Displays the reset information on the drive load group 8, and sends a signal to drive and stop the drive load group 8. Next, the operation of the device configured as described above will be explained using the flowchart shown in Figure 2. When the power supply section 9 of the device is turned on and the control section 2 is started, device control is started according to the procedure of the control program shown in the flowchart of FIG. 2 stored in the ROM in the microcomputer. In step 2l, the microcomputer is started after the power is turned on and after the power is restored, and all information in the microcomputer RAM is cleared and initial settings are performed. In step 22, information about the main power switch 10 is input to the power failure abnormality processing means 14, and it is determined whether the switch is in the ON state or the OFF state. If it is in the ON state, it means that the switch was turned on before the power was turned on, indicating that there was a power outage, and the process proceeds to step 27 to perform the reset process. If it is in the OFF state, it is normal. As an action, proceed to step 23. In step 23, the information on the main t-source switch 10 is input again, and it is confirmed that the switch changes from the OFF state to the ON state. If it remains in the OFF state, it outputs an instruction signal to the device driving means l2 to stop the device. If it is in the ON state, the process proceeds to step 24 as the device is in a standby state where it can be driven. In step 24, an abnormality signal is input from the abnormality detection means 6 to the abnormality processing means 13 in order to determine whether there is any abnormality in the equipment. If an abnormal signal is input, the process proceeds to step 27 to perform a reset process, and if no abnormal signal is input, it is assumed that the process is normal and the process proceeds to step 25. In step 25, the operation switch 3 is
and input the operation instruction signal from the HA@m switch 5,
Determine whether to drive the device. If no driving instruction signal has been input, the process proceeds to step 29 in which the device is placed in a standby state so that it can be driven at any time without being driven; if a driving instruction signal has been input, the process proceeds to step 26 to drive the device. move on. In step 26, an abnormality signal is input from the abnormality detection means 6 in order for the abnormality processing means 13 to determine whether there is any abnormality in the equipment in the standby state.
If an abnormal signal is input, the process proceeds to step 27 to perform a reset process, and if no abnormal signal is input, it is assumed that the process is normal and the process proceeds to step 30. In step 27, a reset process is performed as the device is in an abnormal state.
As the recent punch line processing, the device drive means 12 drives and stops the drive load group 8 according to a preset control procedure, and outputs a control signal to cause the display alarm means 7 to display a reset punch line. In step 28, a stop process is performed to bring the device into a stopped state. As for the stop processing, the device drive means 12 stops the drive load group 8 according to a preset control procedure, and outputs a control signal to cause the display alarm means 7 to display that it is stopped. And driving discrimination means 11
At this time, the operation instruction signals from the operation switch 3 and the IA control switch 5 are cut off so as not to be input. In step 29, a drive standby process is performed to set the device in a drive standby state. As the drive standby process, the device drive means 12 drives and stops the drive load group 8 according to a preset control procedure, and outputs a control signal to cause the display alarm means 7 to display the drive standby state. and,
The operation determination means 11 is permitted to input operation instruction signals from the operation switch 3 and the HA control switch 5. After completing the processing in steps 27, 28, 29, and 30 in this way, the process returns to step 23 and the subsequent processing is repeated. According to the structure of the above embodiment, during a reset due to an abnormal state of the equipment, the operation switch 3 and the HA control switch 5
Since it cannot be released by operating the main power switch 10 and can only be released using the main power switch 10, the user can be prompted to release the switch after confirming the safety of the equipment. Further, even if an erroneous signal is received from the operation switch 3 or the HA control switch 5, the reset punch line will not be canceled automatically. Furthermore, even after the power is restored, the above effects can be achieved by memorizing and retaining device drive and reset information. The above embodiment is shown as an example of the present invention, and any configuration may be used as long as it achieves the purpose and effect of the present invention, and a microcomputer may be used as the control unit. However, even if a microcomputer is not used, a circuit structure that can perform similar control may be used. Further, although the operation switch on the main body of the device and the HA@fa switch were used as the operation switch, any number and installation condition may be used as long as the tact-type operation switch is used.
Further, although a lock type switch is used as the main power switch, a switch or circuit structure that can perform similar control may also be used. More than the effects of the invention, as is clear from the examples, the present invention urges the user to directly visually check the main body of the device in order to instruct the cancellation of the reset state in the HA@ controlled device,
It is possible to prevent unnecessary release from a remote HA control device, and there is no need to consider the influence of erroneous signals due to noise from the operation switch or the HA control switch.

In addition, in the event of a temporary power outage that occurs while the device is running or during a reset, even if the microcontroller's memory is cleared in the initial settings, it will recognize that the device was running and safely return to the power outage reset state. In addition to processing, it is possible to have the user cancel the reset state after always checking the device itself. For this reason, the present invention can improve the safety of HA control equipment.
