Description

  The present invention relates to an operation terminal.

  Conventionally, as shown in FIG. 10, the control master unit 101 and the control slave unit 102 as the control terminal units, the plurality of operation terminal units 103, 104, 105, and the address setting terminal unit 106 are respectively transmitted. A remote control system connected to a two-wire signal line Ls as a path (multi-drop connection) is known (see, for example, Patent Document 1 and Patent Document 2).

  Each of the operation terminals 103, 104, and 105 includes at least one operation switch 103a, 104a, and 105a each having an address set individually, and monitors the operation state of the operation switch 103a, 104a, and 105a included in the operation terminal.

  The control master unit 101 and the control slave unit 102 have a plurality of relays (for example, eight for the control master unit and four for the control slave unit), each of which has an address set individually and is inserted into the power supply path to the load (see FIG. Not shown). The addresses of the operation switches 103a, 104a, 105a and the relay are set by the address setting terminal device 106, respectively.

  The control master 101 sends a transmission signal Vs in the format shown in FIG. 11A to the signal line Ls. The transmission signal Vs includes a start pulse signal ST indicating the start point of the signal, mode data MD indicating the mode of the transmission signal Vs, the relay address of the control unit 102, and the operation switches 103a, 104a, 104 of the operation terminals 103, 104, 105. Address data AD indicating the address of 105a, control data CD indicating the control contents of the relay, checksum data CS for detecting a transmission error, and return signals from the control unit 102 and the operation terminals 103, 104, 105 are provided. This is a bipolar (± 24V) time-division multiplexed signal consisting of a signal return period WT which is a received time slot, and data is transmitted by pulse width modulation as shown in FIG. In the control unit 102 and the operation terminals 103, 104, and 105, the address indicated by the address data AD of the transmission signal Vs received via the signal line Ls is the relay or operation switch 103a, 104a, or 105a that the device has. The control data CD is fetched from the transmission signal Vs and the monitoring data is transmitted by short-circuiting the current mode signal (signal line Ls via an appropriate low impedance) during the signal return period WT of the transmission signal Vs. Signal).

  When data is transmitted from the control master 101 to the control slave 102 and the operation terminals 103, 104, 105, the mode data MD is set to the control mode, and the relays and operation terminals 103, 104, The transmission signal Vs indicating the address assigned to the operation switches 103a, 104a, and 105a included in the address data AD is transmitted to the signal line Ls. Then, the relay assigned to the address shown in the address data AD, the control unit 102 having the operation switches 103a, 104a, and 105a and the operation terminals 103, 104, and 105 fetch the control data CD from the transmission signal Vs (that is, The transmission signal Vs is received), and the monitoring data is returned during the signal return period WT. The control master 101 confirms that the control data CD has been correctly transmitted according to the relationship between the transmitted control data CD and the monitoring data received during the signal return period WT. When the control unit 102 receives the transmission signal Vs in the control mode, the control unit 102 turns on / off the power supply to the load by performing on / off control of the relay of the corresponding address according to the received control data CD.

  Further, the control master unit 101 normally performs polling to transmit the transmission signal Vs in which the mode data MD is set to the dummy mode at regular time intervals, and the operation terminals 103, 104, and 105 are sent to the control master unit 101. When any data is to be transmitted, an interrupt signal Vi as shown in FIG. 11C is generated in synchronization with the start pulse signal ST of the dummy mode transmission signal Vs. At this time, the operation terminals 103, 104, and 105 set an interrupt flag to prepare for subsequent information exchange with the control parent device 101. The control master 101 that has received the interrupt signal Vi sets the mode data MD to the interrupt polling mode and transmits the transmission signal Vs while sequentially increasing the upper half of the address data AD. In the operation terminals 103, 104, and 105 that have transmitted the interrupt signal Vi, the upper half of the address data AD of the transmission signal in the interrupt polling mode indicates that the operation switches 103a, 103, 104 included in the operation terminals 103, 104, and 105 are included. When the upper half bits of the addresses 104a and 105a match, the lower half bits of the address are returned to the control master 101 via the signal line Ls during the signal return period WT. When the control parent device 101 acquires the addresses of the operation switches 103a, 104a, and 105a by the above operation, the mode data MD is set to the monitoring mode, and the transmission signal Vs indicating the acquired address in the address data AD is sent to the signal line Ls. . The operation terminals 103, 104, and 105 that have generated the interrupt signal return data to be transmitted during the signal return period WT of the transmission signal Vs. Finally, the control master 101 transmits a signal requesting an interrupt reset to the operation terminals 103, 104, and 105 that generated the interrupt signal, and clears the interrupt flag of the operation terminals 103, 104, and 105. To do. As described above, the transmission of data from the operation terminals 103, 104, and 105 to the control terminal 101 is performed by four signal transmissions from the control terminal 101 to the operation terminals 103, 104, and 105 (dummy mode, Completed by interrupt polling mode, monitoring mode, interrupt reset). Further, when the control master unit 101 wants to know the operation state of the control slave unit 102, it is only necessary to send the transmission signal Vs in which the mode data MD is set to the monitoring mode.

  The operation of the remote control system is briefly summarized. First, when an operation input is accepted by any of the operation switches 103a, 104a, and 105a, monitoring data corresponding to the accepted operation input is transmitted from the operation terminals 103, 104, and 105 to the control master unit 101. The control master 101 manages the correspondence between the addresses of the operation switches 103a, 104a, and 105a and the relay addresses. When the monitoring data is received, the operation switches 103a, 104a, and 105a that have received the operation input. When the address of one of the relays possessed by itself is associated with the address in advance, the relay is controlled to be turned on / off, and the address of any relay possessed by the control unit 102 is associated in advance Transmits a transmission signal Vs in a control mode instructing on / off control of the relay in the control data CD to the signal line Ls.

In the operation terminals 103, 104, and 105, the operation lights 103b, 104b, and 105b are arranged in parallel with the operation switches 103a, 104a, and 105a, respectively. The indicator lamps 103b, 104b, and 105b are made of, for example, multicolor light emitting diodes, and relays associated with the operation switches 103a, 104a, and 105a are switched by switching the lighting state such as switching of light color or switching of blinking / continuous lighting. ON / OFF (that is, ON / OFF of a load fed through the relay) is displayed. Specifically, for example, according to the transmission signal Vs transmitted in the control mode from the control master 101 when the relay is on / off controlled, the operation terminals 103, 104, and 105 indicate the indicators corresponding to the relays on / off controlled. The lighting state of 103b, 104b, 105b is switched.

  Here, a part of the holding portion 32h of the handle cover 32 is a push portion 32i that pushes the bottom individual switch 41 as shown in FIG. 5 in the closed position. When the individual switch 41 pushed by the pushing portion 32i is pushed, the control unit 14 considers that the individual switch 41 is pushed by the user if the individual switch 41 returns within a predetermined time. On the other hand, if the individual switch 41 has been pressed for a predetermined time or longer, it is determined that the handle cover 32 is in the closed position rather than being pressed by the user. The individual indicator lamp 45 is turned off. That is, the individual switch 41 that is pushed by the push portion 32i serves as an open / close detection means.

  According to the above configuration, when the handle cover 32 is in the closed position and the individual switch 41 is not used, the individual indicator lamp 45 is turned off, so that unnecessary power consumption by the individual indicator lamp 45 is prevented. Moreover, since the light of the individual indicator lamp 45 does not leak through the window body 35, the appearance is improved.

  As shown in FIGS. 6 and 7, the pressing portion 32i is sized and shaped to simultaneously press a plurality of (two in the figure) individual switches 41, and the control portion 14 is pressed by the pressing portion 32i. It may be determined that the handle cover 32 is in the closed position only when all the individual switches 41 that have been pressed are pressed for a predetermined time or longer. If this configuration is adopted, the handle cover 32 is opened when the user continues to press the individual switch 41 or when a failure occurs in the individual switch 41 that does not return to the contact state when the user presses the switch. It is possible to prevent the individual indicator lamp 45 from being turned off regardless of the position.

  Further, for example, the hall sensor 51 is held in the housing 2 as shown in FIG. 8, and the detection magnet 52 is held in the handle cover 32 as shown in FIG. 9, and the hall sensor 51 detects the magnetic field of the detection magnet 52. By doing so, the opening / closing of the handle cover 32 may be determined. However, as the opening / closing detection means for detecting the opening / closing of the housing cover 32, the use of the individual switch 41 as in the present embodiment eliminates the need to separately provide an opening / closing detection means such as the Hall sensor 51, so that the number of parts is reduced. This is desirable because it can be reduced.
