Abstract

PURPOSE:To prevent a malfunction and prank by making standby switch work as a valid/invalid selection switch. CONSTITUTION:When a signal is judged as the one from a device 8 for emergency operation in a central controller 1 by the input of the operation signal from an operation terminal equipment 4 or the device 8, a normal control is performed via a terminal equipment 3 for control. In the case of the signal from the terminal equipment 4, a normal control is performed if a valid/invalid selection switch 4bs is on a valid side by the memory contents of the device 1 where the states of the valid/invalid selection switch 4bs are stored. In the case the control is not inhibited when the switch is on an invalid side the normal control is performed, and the control signal to the terminal equipment 3 is inhibited when the inhibition are required. Which circuit is made invalid and which control signal is inhibited can be freely set by the data registration to the device 1. Therefore, the control inhibition of the whole group can be also performed and the group can be partially inhibited. The release of this setting is performed by the switch 4bs. Thus, the malfunction and prank of the switch can be prevented.

Next, the operation will be described. In FIG. 10, is an arrow indicating the flow of signals. The operation state of the switch provided in the operation terminal 4 or the operation contact 6 connected to the outside is transmitted to the central control unit 1 as operation data as operation data. The central controller 1
According to the registration data set in advance based on this operation data, the control data is transmitted to the control terminal device 3 in order to turn on / off the desired load, and the state data indicating the state of the load 5 is transmitted. It receives as indicated by the arrow and returns the result to the operation terminal 4 as indicated by the arrow. Based on the status data indicated by the arrow, the issuing diode for status display or the output contact provided in the operation terminal 4 is turned on / off. Is the same as the arrow from the emergency operation device 8 to the central control unit 1
Operation data (arrows) and control results to the central controller 1
Status data (arrow) returned from the device to the emergency operation device 8

As an example of registration data, registration data for individual control in which an operation circuit and a control circuit have a one-to-one correspondence is shown. First, as the operation circuit, the address of the operation terminal device 4 and the switch or the operation contact 6 provided therein.
Register the channel number of the input terminal connected to. Next, as the control circuit corresponding to this operation circuit, the address of the control terminal device 3 and the channel number of the output terminal to which the control load is connected are registered. By this registration, the central controller 1 controls the operation circuits and the control circuits in a one-to-one correspondence to perform individual control. In addition, as an operation circuit, an operation signal from an emergency operation device 8 such as a building management system is registered, and a control circuit corresponding to this operation circuit is assigned, so that an emergency operation device such as fire interlock, earthquake interlock, crime prevention interlock, etc. Performs interlocking control. Here, when the switch or the operation contact 6 and the control circuit corresponding to the operation of the emergency operation device 8 are the same, the control is prioritized by the backward push. The above is an example of the individual control, but similarly to the individual control, group control can be performed by registering a plurality of control circuits as control circuits corresponding to the operation circuits.

[0005]

Since the conventional control device for electric equipment is constructed as described above, it is possible to prevent this from occurring during the interlocking control with the emergency operation device such as fire interlocking, earthquake interlocking, and crime prevention interlocking. I do not want to give priority to control and perform control using general operating switches. However, in this situation, there is a problem in that the load operates due to an erroneous operation of the switch or a mischief because the control is prioritized by the back push. Further, there is a problem in that the erroneous operation of the switch and the device for preventing tampering deteriorate the operability and agility in the situation where the user wants to operate the switch.

The present invention has been made in order to solve the above-mentioned problems, and does not include a protective cover or the like,
Alternatively, it is possible to prevent erroneous operation and mischief of the switch without devising the installation location of the switch, and to switch whether to enable or disable the control by the switch operation,
Another object of the present invention is to obtain a control device for electric equipment in which the operation of the switch itself is easy.

[0007]

In a controller for electric equipment according to the present invention, for example, a spare switch of a wall switch, which is one type of operating terminal device, is assigned as a valid / invalid selection switch, and the selection switch By operation,
Regardless of which operation switch is operated, it is possible to prohibit the transmission of the control signal to the control terminal device.
Whether the control circuit is disabled by the selection switch, whether the selection switch is in the alternate operation or the momentary operation, and the timing of invalidation is stored in the memory content of the central control unit that stores the status of the selection switch is “1. "
It is possible to freely set whether it is set to "0" or "0" by registering data in the central control unit.

[0008]

The control device for electric equipment according to the present invention has the above-mentioned means to prevent erroneous operation of the switch or tampering. Further, it becomes easy to switch whether the control by the switch operation is invalid or valid, and to operate the switch itself.

[0009]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to FIG.
It will be described based on. In the figure, 1 to 9 are the same as the above-mentioned conventional device. However, of the switches of the operation terminal 4b, one spare circuit is assigned as the valid / invalid selection switch 4bs. Is an arrow indicating the flow of signals. That is, the operation state of the switch provided in the operation terminal 4 or the operation contact 6 connected to the outside is transmitted to the central controller 1 as operation data as an arrow. The central control device 1 transmits control data to the control terminal device 3 as indicated by an arrow in order to turn on / off a desired load according to registration data set in advance based on the operation data. Further, the status data indicating the status of the load 5 is received as indicated by an arrow, and the result is returned to the operation terminal device 4 as indicated by an arrow. Based on the status data indicated by the arrow, the status display light emitting diode or the output contact provided in the operation terminal 4 is turned ON / OF.
It is supposed to F. Similarly to the arrow, indicates the operation data (arrow) from the emergency operation device 8 to the central control device 1 and the state data (arrow) for returning the control result from the central control device 1 to the emergency operation device 8.

The arrow indicates a valid / invalid selection switch 4b.
It is valid / invalid selection data (arrow) from the operation terminal 4b to which s is assigned and status data (arrow) for confirmation thereof. Based on the status data of the arrow, the light emitting diode 4bd for status display or the output contact provided in the operation terminal 4b can be turned on / off to confirm the valid / invalid state. That is, in the case of valid selection data, boost priority control is performed as in the conventional device. The invalid selection data is processed by the central control unit 1 so that the control state by the signal from the emergency operation device 8 continues even if it is pushed. This is indicated by the light emitting diode 4bd, for example.

FIG. 2 is an operation flowchart of the central control unit 1 in FIG. Now, when an operation signal is input from any of the operation terminals 4 or the emergency operation device 8 (step 10), the central control device 1 first determines whether the operation signal is from the operation terminal 4 or the emergency operation. It is judged from the operation device 8 (step 11), and in the case of the emergency operation device 8, normal control is performed by transmitting a control signal based on the operation signal to the control terminal device 3 (step 1).
2). When the operation signal is from the operation terminal 4, the state of the selection switch 4bs is judged by the memory content of the central control unit 1 which stores the state of the valid / invalid selection switch 4bs (step 13), and the selection switch 4bs is selected. If is a valid side, normal control is performed (step 14), and if it is an invalid side, it is determined whether the circuit is controlled by the control signal or the control is prohibited (step 15). If the determination result does not indicate that the control should not be prohibited, normal control is performed (step 16), and if it is necessary to prohibit the control, transmission of a control signal to the control terminal 3 is prohibited (step 16). Step 17).

Note that which control circuit is invalidated and whether control signal transmission is prohibited can be freely set by registering data in the central control unit 1 for each valid / invalid selection switch. . As a result, it is possible to prohibit the control of all points of the control circuit controlled by an arbitrary operation switch, that is, the control of the entire group, or it is possible to prohibit the control of a part of the group configuration circuit. It should be noted that the cancellation of this setting is performed by each valid / invalid selection switch as necessary.

FIG. 3 shows a case in which the control circuit by the operation switch and the control prohibiting circuit by the valid / invalid selection switch 4bs are the same, and the control of the entire group is prohibited. FIG. 4 shows a case where a part of the control circuit by the operation switch is the control prohibition circuit by the enable / disable selection switch, which is particularly important in the group configuration circuit, and only the part where the control is to be prohibited is selected and prohibited. As for the part that does not hinder the control, normal control is performed to enhance versatility that can handle various operational cases. On the contrary, FIG. 5 shows a case where the control circuit group (a plurality of groups) formed by a plurality of operation switches is collectively prohibited, and the versatility can be improved and the number of valid / invalid selection switches can be reduced at the same time. .

FIG. 6 shows how the effective / ineffective state of the control by the operation switch changes when the alternate operation of the effective / ineffective selection switch which is a normally open switch is performed. By pressing the selection switch, it is possible to easily and alternately switch between enabling and disabling the control by the operation switch. As shown in the figure, the valid / invalid state is determined by the memory content of the central control unit 1 that stores the state of the valid / invalid selection switch. For example, when the memory content is "1", the operation switch is pressed. Invalid, when "0", the operation switch is valid.

The light emitting diode for status display provided in the valid / invalid selection switch is turned on by the memory content of the central control unit 1 storing the state of the valid / invalid selection switch, and when the memory content is "1". Is lit red, and when it is "0" it is lit green. That is, it can be determined that the operation switch is invalid when the light-emitting diode of the valid / invalid selection switch is lit in red, and is valid when the light is in green.

FIG. 7 is a timing chart when the valid / invalid selection switch, which is a normally open switch, is momentarily operated, and the operation switch is valid only while the valid / invalid selection switch is being pushed down. That is, effective /
Since the operation switch becomes effective only when the invalidation selection switch and the operation switch are pressed at the same time, it is possible to prevent erroneous operation mischief similar to a switch with a cover. The valid / invalid state is determined based on the memory content of the central control unit 1. When the memory content is "1", the operation switch is valid, and when it is "0", it is invalid. Also,
The light emitting diode for status display provided in the valid / invalid selection switch is also lit according to the memory content of the central control unit 1, and is lit in red when the memory content is “1” and lit in green when the memory content is “0”. Therefore, the operation switch becomes effective only when the light-emitting diode is lit in red with the effective / ineffective selection switch depressed.

FIG. 8 shows a modification of the relationship between the light emitting diode lighting state of the valid / invalid selection switch and the valid / invalid state of the operation switch in FIG. 6, and the determination of the valid / invalid state is made by the memory of the central control unit 1. The operation switch is enabled when the content is "1", disabled when it is "0", and the status display LED is lit red when the memory content is "1" and green when the memory content is "0". I am trying. That is, it can be determined that the operation switch is valid when the light-emitting diode of the valid / invalid selection switch is lit in red and invalid when the light-emitting diode is lit in green.
The change in the valid / invalid relationship of the operation switch is set so that the user of this device can easily understand the change.

As shown in FIGS. 6 to 8, it is possible to meet various demands of operability and recognizability that differ depending on the user. This selection can be made freely by registering data in the central control unit 1. It can be set to. FIG. 9 is a diagram showing a switch allocation example, and the validity / invalidity and priority order of the switch operation in the allocation example.

[0019]

As described above, according to the present invention, a spare switch is assigned as a valid / invalid selection switch, and by operating this switch, each operation switch such as an individual switch or a group switch is disabled. It is possible to prevent erroneous operation of the switch from being tampered with, and to register to the central control unit 1 which spare switch the valid / invalid selection switch is and the operation state of the invalidation timing. Since it can be set more freely, there is an effect that it is possible to flexibly meet various requests of users.
