  The best mode for carrying out the present invention will be described below with reference to the drawings.

  The time switch 10 of the present embodiment is used by being connected to the transmission line Ls in a remote monitoring control system as shown in FIG.

  This remote monitoring control system includes a control master device 1 as a transmission control terminal connected to a time switch 10 via a transmission line Ls.

  The control main unit 1 has a plurality of (eight in the figure) relays 6 inserted into a power supply path to a load (not shown) such as a lighting load or a ventilation fan, respectively, and each of which is assigned an address, and a transmission line Ls. When an operation signal is input from, if there is a relay 6 having an address previously associated with the address of the trigger means included in the operation signal, the relay 6 is opened / closed according to the content of the operation signal. Thus, the load connected to the relay 6 is on / off controlled. That is, the control base unit 1 is also a load side terminal. In addition, a load-side terminal (not shown) to which a load is connected may be connected to the transmission line Ls, and the control master unit 1 can load a load when an operation signal is input. A control signal for instructing the terminal device to control the load is output to the transmission line Ls. In the load-side terminal, each connected load has an address individually set in advance. Correspondence between the address of the trigger means and the address of the load is set in advance in the control base unit 1, and the control signal includes the address of the load to be controlled and the content of the control. The load side terminal controls the load according to the control content included in the control signal when the load address included in the control signal input from the transmission line Ls matches the load address of the load terminal. To do. As the control to be performed, in addition to individual control for controlling one load corresponding to the trigger of one trigger means, a plurality of loads are controlled collectively corresponding to the trigger of one trigger means. There are group control, pattern control for controlling a plurality of loads to a predetermined state individually set corresponding to the trigger of one trigger means, and the like. When the relay 6 is opened or closed, or when transmission of a control signal for instructing control of a load is completed, the control base unit 1 emits light to display the corresponding load state to the control terminal that has transmitted the operation signal. A control signal for instructing control of the diode or the like is generated and sent to the transmission line Ls. Here, a known multiplex transmission technique such as polling can be used for signal transmission / reception via the transmission line Ls as described above.

  The time switch 10 is capable of a program operation for automatically outputting an operation signal in accordance with a preset control program in addition to an operation as a normal control-side terminal that outputs an operation signal corresponding to an operation input. is there.

  Hereinafter, the time switch 10 will be described in detail.

  As shown in FIG. 3, the time switch 10 includes a signal processing unit 11 formed of a microcomputer, a signal transmission / reception unit 12 that is connected to the signal line Ls via the signal line connection terminals T <b> 1 and T <b> 2, and transmits and receives a transmission signal; A program storage unit 13 comprising a non-volatile memory such as an EEPROM for storing a control program and various setting contents described later, a clock transmission circuit 14 for supplying a clock signal to the clock unit 11a of the signal processing unit 11, and an operation A key input unit 15 to which an input is given, a liquid crystal display unit 16 which is composed of a liquid crystal panel and is controlled by the signal processing unit 11 to display various setting contents, and an LED display unit which displays various setting contents and the operating state of the load 25, a buzzer circuit 17 for generating an operation sound and an error sound of the key input unit 15, and a transmission circuit 18 for supplying an operation clock to the signal processing unit 11. A reset circuit 19 that resets the signal processing unit 11, and a power supply circuit 20 that obtains an operating power supply by smoothing and stabilizing a DC power source obtained by full-wave rectifying the transmission signal input from the signal line Ls by the diode bridge DB; The power supply voltage detection circuit 21 for detecting a power failure by monitoring the power supply voltage of the power supply circuit 20 and the capacitor charged when energized as a power source are supplied to the signal processing unit 11 when a power failure occurs, and the clock unit 11a keeps time. A backup power supply circuit 22 that backs up the sensor, a sensor receiving circuit 23 that detects a change in the output of the heat ray sensor 7 as a human sensor connected to the sensor connection terminals T3 and T4, and supplies it to the signal processing unit 11, and an external contact connection terminal An external contact detection circuit 24 that detects conduction between T5 and T6 and inputs the detection result to the signal processing unit 11 is provided.

  The power supply voltage detection circuit 21 detects a power failure by monitoring the power supply voltage of the power supply circuit 20 and inputs a power failure detection signal to the signal processing unit 11. When the power failure detection signal is input from the power supply voltage detection circuit 21, the signal processing unit 11 shifts to a standby mode in which the functions other than the minimum necessary functions such as the clock unit 11 a are stopped to reduce power consumption. In the standby mode, the clock unit 11a is supplied with power from the backup power supply circuit 22 and continues the clocking operation for a predetermined power failure compensation time. If the power failure continues for more than the power failure compensation time, the clock unit 11a stops and the current time is lost. Therefore, it is necessary to reset the time after the power is restored, but a program that stores data such as programs and various setting information Since the storage unit 13 is composed of a nonvolatile memory, the data is not lost due to a power failure.

  The signal transmission / reception unit 12 is controlled by the signal processing unit 11 and transmits a control signal in response to an operation input to the key input unit 15 or a control signal transmitted from the control master unit 1 to instruct the control of the LED display unit 25. Receive.

  The program storage unit 13 stores a control program composed of a set of a control address and a control time, and the signal processing unit 11 measures the current time (in this embodiment, the day of the week and the time) counted by the built-in clock unit 11a. (Minute) coincides with the control time of one of the control programs, and the signal transmission / reception unit 12 is controlled and the same as when the trigger means having the control address set in the control program as an address generates the trigger An operation signal is transmitted to the control parent device 1 via the transmission line Ls. If the address of the trigger means previously associated with a plurality of loads is set as the control address, group control for controlling a plurality of loads at once, or a predetermined state for each of the plurality of loads. Pattern control to be controlled can be performed by a program operation.

  For the input of the control program, a key input unit 15 and a liquid crystal display unit 16 that give operation inputs to setting input buttons 45a to 45f and a load operation button 46a described later to the signal processing unit 11 are used. Further, the liquid crystal display unit 16 displays the contents being set, the current time, the operation mode of the signal processing unit 11, and the like.

  Here, the control program is basically set in units of days, and the control time is basically a combination of day of the week and hour and minute. In addition, since only a part of the load may be controlled on a specific day such as a holiday, a control program (hereinafter referred to as a “specific day program”) that operates on a specific day is set out of the control programs. The control program other than the specific day program is not executed on the specific day. For example, if you do not want to turn on the room light on holidays, but want to turn on the outdoor light, for example, at a business office, if only the control program whose control address is the address associated with the outdoor light is set as the specific day program, Only the outside light can be turned on without lighting. The signal processing unit 11 is one of an automatic operation state in which a program operation is performed according to all control programs, a holiday operation (a specific day operation) state in which a program operation is performed only in accordance with a specific day program, and a stop state in which no program operation is performed. Take the driving state. Switching between the automatic operation state and the holiday operation state is performed according to the output of the external contact detection circuit 24 that detects the connection between the external contact connection terminals T5 and T6. That is, when the external switch SW connected between the external contact connection terminals T5 and T6 is turned on (that is, when the external contact connection terminals T5 and T6 are short-circuited), the signal processing unit 11 operates automatically. When the external switch SW is turned off (that is, when the external contact connection terminals T5 and T6 are insulated), the signal processing unit 11 takes a holiday operation state. Note that in any of the automatic driving state, the holiday driving state, and the stopped state, an operation signal is output in accordance with an operation input to a load operation button 46a (described later) included in the key input unit 15.

  Further, in the control program, it is possible to set the control according to the output of the heat ray sensor 7 connected to the sensor connection terminals T3 and T4. The heat ray sensor 7 is a human sensor that detects a human body by detecting a heat ray emitted from the human body. For example, the human body is within a detection range by comparing the intensity of the detected heat ray with a predetermined threshold. It is determined whether or not it exists, and the output voltage is changed in two steps, high and low, according to the determination result. The sensor receiving circuit 23 functions as a trigger unit that generates a trigger when a human body is detected by any one of the heat ray sensors 7 connected to the sensor connection terminals T3 and T4. The signal processing unit 11 operates based on the output of the sensor receiving circuit 23, thereby operating signals according to whether or not a human body exists within the detection range of the heat ray sensor 7 connected to the sensor connection terminals T3 and T4. Can be generated. Further, whether or not to generate an operation signal according to the output of the heat ray sensor 7 can be switched by a control program. That is, the operation of turning on the illumination load when the human body is detected by the heat ray sensor 7 is performed only from 7:00 am to 7:00 pm, and the operation is performed even if the human body is detected by the heat ray sensor 7 in other time zones. You can not.

  Here, when the sensor connection terminals T3 and T4 and the sensor receiving circuit 23 are not provided, in order to realize the control as described above, for example, it is necessary to provide the human sensor main unit 7A shown in FIG. 4A is a sensor that outputs an operation signal to the transmission line Ls in accordance with the output of the own heat ray sensor (not shown) or the output of the human sensor 7 connected thereto. It is a kind of control side terminal that performs the operation. In addition to the address of the trigger means, the human sensor base unit 7A is also assigned a load address, and switches on / off the sensor operation according to a control signal transmitted to the load address. That is, the configuration of FIG. 4 is controlled by the time switch 10 so that the load control (sensor operation) by the human sensor main unit 7A is performed only in a certain time period. On the other hand, in this embodiment, it is not necessary to provide a control side terminal device like the human sensor base unit 7A.

  As shown in FIG. 5, the time switch 10 includes a housing 30 that houses the above-described parts. The housing 30 is a so-called two-piece embedded wiring device arranged in the short-width direction having three module dimensions (a shape in which three embedded wiring devices having unit dimensions defined in JIS standards are arranged in the short-width direction). It is formed to have substantially the same dimensions as the dual module dimensions, and is embedded in a construction surface such as a wall surface with the front surface exposed. On the front side of the housing 30, on the right side of the center in the left-right direction, a liquid crystal display unit 16 and six setting input buttons 45a to 45f as handles of the setting input unit 10a are provided. On the left side, four load operation buttons 46a are provided as handles of the load operation unit 10b. On the front surface of each load operation button 46a, indications (not shown) of “A”, “B”, “C”, and “D” indicating names given to the load operation buttons 46a are respectively attached. On the left side of each load operation button 46a, the operation state of the load associated with the load operation button 46a is assigned to the operation display window 46b displayed by the LED display unit 25 and the load operation button 46a, respectively. A function display window 46c for displaying functions is provided.

  Further, on the display surface exposed to the front of the housing 30 in the liquid crystal display unit 16, as shown in FIG. 6, the program number display unit 16a for displaying the program number assigned to the control program, and the operation based on only the time. Control method display unit 16b for displaying whether the setting is related to the control program (timer) to be set or the setting related to the control program (heat ray sensor) related to the heat ray sensor 7, and the current time and control time are displayed in units of hours and minutes, and addresses are displayed The time display unit 16c used for the day of the week, the day of the week display unit 16d for displaying the day of the week, the operation / non-operation display unit 16e for displaying whether or not the program operation is performed for each day of the week, and the current processing unit 11 A mode display unit 16f for displaying the operation mode, an operation display unit 16g for displaying the current operation state of the signal processing unit 11, and Load display section 16h for displaying whether the load operation button 46a is a setting target, a function display section 16i for displaying the function of the load operation button 46a, and a sensor status display section for displaying the type of operation by the heat ray sensor 7 16j, a control content display unit 16k for displaying ON or OFF control content, and a summer time display unit 16m for displaying whether or not the operation is shifted to a summer time operation to be described later.

  Hereinafter, an operation method of the time switch 10 will be described.

  The setting input buttons 45a to 45f include a mode selection button 45a, an operation switching button 45b, an UP button 45c, a DOWN button 45d, a return button 45e, and a setting button 45f.

  The mode selection button 45a switches the operation mode of the signal processing unit 11. That is, each time the mode selection button 45a is pressed, the operation mode of the signal processing unit 11 displayed on the mode display unit 16f is the normal mode, the pattern / group setting mode, the operation time setting mode, the address setting mode, the current setting mode, It switches cyclically in the order of time setting mode, holiday operation setting mode, normal mode. In each mode, except for the pattern / group setting mode, the mark displayed on the liquid crystal display unit 16 is moved below the character corresponding to each mode. For the pattern / group setting mode, “ This is indicated by a flashing mark under the word “normal”. Here, the normal mode is a mode in which an operation signal is generated and output to the transmission line Ls in accordance with an operation input to the load operation button 46a or a control program, and the pattern / group setting mode is for pattern control or group control in advance. This is a mode for setting the load and control content (for pattern control) associated with the set load operation button 46a. The operation time setting mode is a mode for setting the content of the control program. Is a mode for assigning an address to the load operation button 46a. The current time setting mode is a mode for setting the current day of the week and hour and minute. The holiday operation setting mode is a mode for setting a specific day program.

  In each setting mode, the content being set is displayed on the liquid crystal display unit 16 at a position corresponding to the setting item. The displayed setting contents are cyclically switched in the direction corresponding to the pressed button by pressing the UP button 45c or the DOWN button 45d, and are confirmed by pressing the setting button 45f. At this time, the setting content can be fast-forwarded by long-pressing the UP button 45c or the DOWN button 45d (for example, by pressing and holding it for one second or longer). For example, when the setting content is minutes, if the UP button 45c is pressed and held, the setting minute displayed on the time display unit 16c can be increased by 10 minutes instead of the usual 1 minute. When the return button 45e is pressed, the currently selected content is discarded, and if the item being set is the second or later item set in the setting mode, resetting of the item set immediately before is started. can do.

  Next, each setting mode will be described.

  First, the address setting mode will be described. In the address setting mode, first, the load operation button 46a for setting an address is selected by pressing, and after confirming that the selected load operation button 46a is displayed on the load display portion 16h, the setting button 45f is selected. Press to confirm. Next, a function set to the load operation button 46a is selected while referring to the function display unit 16i. The functions set are “individual” associated with individual control, “P (pattern)” associated with pattern control, “G (group)” associated with group control, and all loads of the remote monitoring control system are turned on. “All ON” used as a trigger to perform, and “All OFF” used as a trigger to turn off all loads of the remote monitoring control system can be selected. An address is assigned to each function, and the address is always different if the function is different. The control base unit 1 turns on all the relays 6 and outputs a control signal for instructing to turn on all the loads to the transmission line Ls when an operation signal due to the trigger means of the address assigned to all ON is input. When an operation signal resulting from the trigger means of the address assigned to all OFF is input, all the relays 6 are turned off and a control signal for instructing all loads to be turned off is output to the transmission line Ls.

  When any one of the functions of all ON and all OFF is selected, the address setting is completed as it is, and when any of the functions of individual, P, and G is selected, the time display unit 16c displays the address number. The address setting is completed by setting the address number while referring to FIG. After the address setting is completed, the state returns to the state of selecting the load operation button 46a. Therefore, when the address setting of the other load operation buttons 46a is not performed, the mode selection button 45a is pressed to set the signal processing unit 11 to the normal mode. return.

  Next, the pattern / group setting mode will be described. In order to set the contents of pattern control or group control in this mode, one or two of the load operation buttons 46a are associated with the pattern control or group control in advance, and a plurality of load operation buttons 46a. Must be associated with individual control. After selecting the pattern / group setting mode, first, the operation switching button 45b is pressed. Then, the signal processing unit 11 controls the signal transmitting / receiving unit 12 to output a predetermined switching signal to the transmission line Ls. When receiving the switching signal, the control base unit 1 switches from the normal mode in which the load is controlled according to the operation signal to the setting mode in which the correspondence between the address of the trigger means and the load address is set according to the operation signal. . Thereafter, the load operation button 46a associated with the pattern control or group control whose contents are to be set is selected by pressing the setting button 45f after the pressing operation and confirming. Next, the load operation button 46a associated in advance with the individual control of the load to be subjected to pattern control or group control is selected by pressing the setting button 45f and confirming it after the pressing operation. Here, in the case of group control, every time the load operation button 46a is pressed, whether or not it is subject to group control is alternately switched. In the case of pattern control, every time the load operation button 46a is pressed, at the time of pattern control. The setting content is cyclically switched, such as ON → OFF during pattern control → Not subject to pattern control → ON during pattern control, and the LED display unit 25 displays light emitting diodes 43a to 43d (see FIG. 7) according to the setting content. The display in the operation display window 46b is switched by controlling the lighting state. Here, whether the light is turned on or off at the time of pattern control is expressed by, for example, the color difference of the light emitting diodes 43a to 43d to be lit or the presence or absence of blinking. When the operation switching button 45b is pressed after the input is completed, the signal processing unit 11 operates according to the input content to indicate the pattern control or group control content associated with the load operation button 46a. And a predetermined switching signal are generated, and the operation signal and the switching signal are output from the signal transmitting / receiving unit 12 to the control parent device 1 via the transmission line Ls. The control master unit 1 updates the setting according to the operation signal received from the transmission line Ls, and returns to the normal mode from the setting mode when receiving the switching signal. Finally, the mode selection button 45a is pressed to return the operation mode of the signal processing unit 11 to the normal mode. Since the present embodiment has the pattern / group setting mode as described above, the contents of pattern control and group control can be set without using a separate device such as a known pattern / address setting device. .

  Next, the operation time setting mode will be described. In the operation time setting mode, first, the number of the control program whose contents are to be set is specified with reference to the number displayed on the program number display unit 16a. Next, it is designated by pressing the load operation button 46a previously associated with the load to be operated by the control program, and after confirming that the load is correctly selected with reference to the load display portion 16h, the setting is made. Press button 45f to confirm. That is, by pressing the load operation button 46a, an address set in advance for the load operation button 46a is designated as a control address. Here, when the load operation button 46a is pressed before the control program number is specified, the control program number is selected next. In this case, the number displayed as an option is already the load operation button. The number is limited to the number of the control program set in the button 46a and the number of the control program whose contents are not yet set.

  Further, instead of the load operation button 46a, a function and an address (that is, a control address) can be directly designated. In this case, after designating the control program number without designating the load operation button 46a, the function is selected in the same manner as the address setting while referring to the function display unit 16i. Here, when all ON or all OFF is selected, the operation is the same as when the load operation button 46a for which the function is set is designated. Further, when any of the individual, P, and G functions is selected, an address number is further designated. In this case, the operation is the same as when the load operation button 46a in which the function and address number are set is designated. Here, if an address other than the address set in the load operation button 46a is designated, a load other than the load associated with the load operation button 46a can be controlled by the control program.

  In any of the above cases, once the control program number and the load operation button 46a or the control address are designated, the timer control or the heat ray sensor control is set with reference to the control method display unit 16b. select.

  When the timer control is selected, next, the control is performed with reference to the time display unit 16c (that is, an operation signal similar to that when the load operation button 46a having the control address is pressed is transmitted to the signal transmitting / receiving unit 12). Control time to be output to the transmission line Ls) in the order of hour and minute. After the control time is set, it is set whether the load is turned on or off during control according to the control program. That is, at least an operation signal output according to the control program among the operation signals includes information for instructing on / off of the load. If the specified load operation button 46a is set to P or all ON or all OFF function, or if P or all ON or all OFF function is specified when the control address is specified, The load on / off setting is not performed.
