Description

  The present invention relates to a monitoring control apparatus used in a remote monitoring control system that performs load monitoring control by communication.

  2. Description of the Related Art Conventionally, a technique for transmitting a transmission signal including on / off information of a switch through a signal line to perform remote monitoring control of a load and opening / closing a relay for turning on / off a load by the transmission signal is known.

  As this type of remote monitoring and control system, a centralized control type equipped with an operation terminal having a switch and a control terminal having a relay for turning on and off a load as a terminal device and a transmission unit as a center device. There is something. A plurality of operation terminals and control terminals may be provided. The transmission unit, the operation terminal, and the control terminal are connected to a two-wire signal line, and the transmission unit is connected to the operation terminal and the control terminal by using terminal addresses set individually for the operation terminal and the control terminal. Recognize each control terminal separately.

  The transmission unit includes a memory that stores a control table that is a data table in which operation terminals and control terminals are associated with each other by addresses. When this switch unit is notified of switch ON / OFF information in any of the operation terminals using a transmission signal (using a time division multiplex transmission signal), the transmission unit is associated with the operation terminal by the control table. An instruction to open / close the relay is transmitted to the control terminal using the transmission signal. In response to this instruction, the relay is opened and closed in the control terminal. Therefore, the load is controlled according to the on / off state of the switch.

  Here, generally, each operation terminal has a switch of a plurality of circuits, and a load of a plurality of circuits is connected to each control terminal. The control table provided in the transmission unit can be associated with each switch and load circuit. In other words, for example, when the operation terminal has a plurality of switches, only the terminal address unique to the operation terminal corresponds to all the switches provided in the operation terminal, and the only switch actually operated Cannot be specified. Therefore, in each operation terminal, a load number is assigned to each switch, and the only switch actually operated is used by adding the load number after the terminal address of each operation terminal as the switch address. Can be specified. Similarly, in the control terminal, a load number is assigned for each load, and a load address is added to the terminal address of each control terminal after the load address. Note that one load circuit may be configured by a plurality of loads connected to one control terminal, and in this case, the terminal address of each control terminal is used as the load address.

  By the way, in the control table, it is possible to tie the switch and the load one-to-one or one-to-many. For example, if the power supply to the lighting fixture as a load is turned on and off in the remote monitoring control system, the transmission unit individually controls the lighting fixtures of one circuit to be turned on and off with one switch, and 1 A single switch can be set to collective control for collectively turning on and off a plurality of lighting fixtures. In other words, the individual control means that the load of one circuit is controlled by one instruction, and the collective control means that the loads of a plurality of circuits are controlled by one instruction. Such collective control includes group control and pattern control. In group control, a range of a load to be controlled is associated with a switch in advance, and the load in the range is turned on or off at once by operating one switch. In pattern control, the address range of the load to be controlled and the on / off state of the load corresponding to each address are associated in advance with the switch, and the load in the range is respectively controlled by operating one switch. Turn on or off.

  In order to perform the group control or pattern control described above, in the control table of the transmission unit, the address of the load in the range to be controlled is associated with the group number or pattern number corresponding to the switch that performs group control or pattern control. is there. When a switch that performs group control or pattern control is operated, the transmission unit expands the address of the load to be controlled by collating with the control table, and further determines the load on and off states. Thereafter, an instruction is given to the control terminal having the address obtained by referring to the control table.

  Here, for example, if it is attempted to control the operation of each load in a place where there are a large number of loads such as a conference room, a large number of switches are required, resulting in a problem that the space occupied by the operation terminal increases. Here, if group control or pattern control is performed, individual operations of a plurality of loads can be controlled by one switch operation. However, in order to perform group control, it is necessary to set in advance which loads are to be controlled collectively, and in order to perform pattern control, it is necessary to set in advance which load is to be controlled in what state. is there. Therefore, an operation unit for performing these settings is required, and eventually the required number of switches is increased and the space occupied by the operation terminal is increased.

  Therefore, as a monitoring control device used as an operation terminal in the above-described remote monitoring control system, a display panel made up of a liquid crystal display and an operation input unit made up of a transparent touch switch arranged over the screen of the display panel. There has been proposed a device which is provided in a body and performs load control according to an operation input of an operation input unit associated with display contents of a display panel and a screen display according to a load state (for example, see Patent Document 1). . The container of the monitoring control device is attached to the wall so that the rear part is housed in an attachment hole formed in the wall, and the front part projects forward from the wall surface.

  This monitoring control device is configured to be able to set the display content (screen display) of the display panel and the response (load control) to the operation of the operation input unit. Therefore, the operation input unit can have various functions depending on the setting contents. In addition, since the display content of the display panel can be changed according to the function of the operation input unit, multi-function operation is possible in a limited space, and even when a large number of loads are operated, the operation terminal The space occupied by the vessel can be reduced.

  Furthermore, in this monitoring and control device, an operation mode for controlling the load in response to an operation of the operation input unit associated with the display content of the display panel, a display content of the display panel, and a response to the operation of the operation input unit are set. The setting mode to be switched can be switched. Thus, by operating the monitoring control device in the setting mode, it is possible to perform settings related to screen display of the display panel and load control (contents of group control and pattern control).

  The monitoring control apparatus described in the following embodiments is used as an operation terminal in the remote monitoring control system shown in FIG. The basic configuration of this remote monitoring control system is the same as that of the remote monitoring control system described in the background art section.

Specifically, in the example of FIG. 2, the load L includes an incandescent lamp L ₁ , a fluorescent lamp L ₂ having an inverter type lighting device, a fan coil L ₃ of an air conditioner, and a speaker L ₄ . Incandescent _{L 1} is an incandescent lamp dimming control terminal of the capacitance corresponding to the number of lamps (1500 W, 800 W, 500 W) is controlled by 33A to 33C. Fluorescent L ₂ is controlled by a fluorescent lamp dimming control terminal 33E for controlling the control terminals 33D and the optical output having a relay for controlling the turning on and off. Fan coil L ₃ is controlled in three stages a medium is strong action intensity by fan coil control terminals 33F weak, speaker L ₄ are the volume is controlled by the volume control terminal 33G. It is also possible to use an electric curtain, an electric screen, a fan for ventilation, etc. as other loads.

The operation terminal, the operation terminal 31A having a switch S _0, and dimming operation terminals 31B, 31C, the contact input operation terminal 31D to connect the various sensors contact output is obtained provided. Furthermore, an operation unit can be configured by providing an operation unit in the wireless transmitter 34a and combining it with the wireless receiver 34b. In order to extend the signal line Ls, in the illustrated example, a repeater (amplifier) 35 is inserted on the signal line Ls so that the transmission signal can be transmitted without being attenuated. In the illustrated example, two monitoring control devices 1A and 1B (hereinafter simply referred to as monitoring control device 1 when they are not distinguished from each other) as operation terminals are connected, and one monitoring control device 1A has a commercial power supply ( For example, AC 24V power is supplied from a remote-control transformer 36 that is a step-down transformer that steps down and outputs AC 100V). Hereinafter, when the operation terminals 1A, 1B, and 31A to 31D are not distinguished from each other, the operation terminal 31 is simply referred to, and when the control terminals 33A to 33G are not distinguished from each other, they are simply referred to as the control terminal 33.

  Here, the transmission unit 30 periodically transmits a transmission signal to the signal line Ls, and a bipolar pulse width modulation signal of, for example, ± 24V is used as the transmission signal. The operation terminal 31 and the control terminal 33 other than the monitoring control device 1 secure an internal power supply by full-wave rectifying this transmission signal. The transmission unit 30 is supplied with power by a commercial power source.

  Below, operation | movement of the above-mentioned remote monitoring control system is demonstrated easily.

  The transmission unit 30 always performs polling to periodically transmit a transmission signal whose terminal address is changed cyclically to the signal line Ls. The transmission signal includes a start pulse indicating the start of signal transmission, mode data indicating the signal mode, address data for transmitting a terminal address for calling the operation terminal 31 and the control terminal 33 separately, and for controlling the load L. Control data (including a load number) for transmitting control data, checksum data for detecting a transmission error, and a signal return period that is a time slot for receiving a return signal from the operation terminal 31 or control terminal 33 Bipolar signals are used.

  When a monitoring input by a switch operation or the like is generated in any of the operation terminals 31, the operation terminal 31 sends an interrupt signal synchronized with the start pulse of the transmission signal to the signal line Ls. The operation terminal 31 that has generated the interrupt signal enters a latch state in which the interrupt flag is set. On the other hand, when the transmission unit 30 detects the interrupt signal, it transmits a transmission signal in which the mode data is the search mode. When receiving the search mode transmission signal, the operation terminal device 31 in the latched state returns the terminal address in the signal return period, and the transmission unit 30 receiving the terminal address latches the operation terminal device 31 of the terminal address. It is confirmed that the operation terminal 31 has generated the interrupt signal by transmitting a transmission signal for requesting the return of the state and confirming whether the state is a latched state. If it is confirmed that the operation terminal 31 has generated the interrupt signal, a transmission signal for releasing the latch state is transmitted, and the latch state of the operation terminal 31 is released.

  When the transmission unit 30 receives a request from the operation terminal 31 through the above-described operation, the transmission unit 30 requests the control terminal 33 associated with the operation terminal 31 to control the load L according to the control table. Next, a transmission signal for confirming the state of the load L to be controlled is sent out, and the load state is returned from the control terminal 33. The load state received from the control terminal 33 is confirmed by the transmission unit 30, and if the current load state is off, a transmission signal having a content that reverses the load state to on is transmitted to the operation terminal 31 that has received the monitoring input. At the same time, a transmission signal having the same content is transmitted to the control terminal 33. In addition, the transmission signal of the content which controls the control terminal 33 is transmitted also to the operation terminal 31 in order to reflect in display states, such as the indicator lamp for the on-off display provided in the operation terminal 31. Upon receiving the transmission signal indicating the load state, the control terminal 33 returns a reception confirmation.

The remote monitoring and control system described above, when the switch S ₀ of the operation terminal 31 is operated, the address of the switch S ₀ (terminal address + load number) is collated with the control table in the transmission unit 30, switches S ₀ A transmission signal for instructing control of the load L is transmitted from the transmission unit 30 to the control terminal 33 connected to the load L for which the correspondence relationship is set. By such an operation, the on / off information of the switch S ₀ can be reflected in the control of the load L.

(Embodiment)
As shown in FIG. 3, the monitoring control device 1 of the present embodiment includes a display panel 2 in which a backlight is integrated with a liquid crystal display, and a transparent plate-like shape that is disposed on the screen (front surface) of the display panel 2. And an operation input unit 3 including a touch switch. The display panel 2 uses a matrix display type in which a large number of pixels are arranged in a matrix form vertically and horizontally, and displays a figure by a combination of pixels. The operation input unit 3 is a resistive pressure-sensitive touch in which a large number of contact portions made of transparent electrodes are arranged on a transparent sheet-like member, and which part is touched when a finger touches the sheet-like member. It is a switch and constitutes a touch panel display together with the display panel 2.

  The monitoring control device 1 includes a communication circuit 11 that is connected to a signal line Ls connected to the transmission unit 30 and that transmits and receives a transmission signal (communication command). The communication circuit 11 is connected to a main microcomputer 12 as a control unit, and the main microcomputer 12 operates according to a program and data written in a flash memory 13 provided as a built-in memory of the monitoring control device 1. In the flash memory 13, at least an address as the operation terminal 31 is written. Further, at least an area for writing setting information set using an external storage medium described later is secured in the flash memory 13.

  The main microcomputer 12 outputs data indicating the display contents of the display panel 2 to the liquid crystal controller 15 through the latch circuit 14. The liquid crystal controller 15 displays predetermined contents at predetermined positions on the display panel 2 using data registered in advance in the DRAM 16. The contrast of the display panel 2 and the brightness of the backlight are automatically adjusted by the main microcomputer 12 controlling the contrast adjusting unit 17 and the backlight inverter circuit 18. Further, the main microcomputer 12 has a function of causing the buzzer 19 to ring according to the operation of the operation input unit 3.

  By the way, the monitoring control device 1 of this embodiment has a socket 4 into which a memory card MC (see FIG. 5) made of an SD memory card (registered trademark) as an external storage medium is detachably mounted. Then, the main microcomputer 12 communicates with the memory card MC in a state in which the memory card MC is mounted, whereby the stored contents of the memory card MC can be transferred to and from the flash memory 13. Here, setting information regarding screen display and load control of the display panel 2 is stored in the memory card MC in advance, and the setting information is transferred to the flash memory 13 so that the main microcomputer 12 stores the setting information. Based on this, screen display and load control can be performed.

  That is, when the memory card MC is inserted into the socket 4, the main microcomputer 12 automatically performs settings related to screen display and load control of the display panel 2 in accordance with setting information in the memory card MC. When the above setting is completed (that is, when the transfer of the setting information to the flash memory 13 is completed), there is no problem in the operation of the monitoring control device 1 even if the memory card MC is removed. The monitoring control device 1 may be used with the card MC mounted.

  The types of settings that can be performed using the memory card MC include, for example, settings related to group control / pattern control described in the background art section (that is, settings for which loads L are controlled collectively in group control, There is a setting regarding which load L is controlled in what state in pattern control), a setting relating to schedule control for controlling the load L in association with time, and a setting relating to various types of information displayed on the display panel 2. In addition, when a simple map of a building employing a remote monitoring control system is displayed on the display panel 2 and the load L is monitored and operated with a symbol representing the load L on the map, the data of this map is set. It can also be information. Further, initial setting such as password setting and presence / absence of operation sound of the operation input unit can be performed using the memory card MC.

Then, regarding the setting contents to be reflected in the control table of the transmission unit 30 like the settings related to the group control / pattern control, it is assumed to be transferred from the communication circuit 11 to the transmission unit 30 via the signal line Ls. That is, since the correspondence relationship between the switch S ₀ and the load L is managed in the control table of the transmission unit 30, the transmission unit 30 receives the setting content set by the monitoring control device 1, thereby It is possible to change the control table so that the contents are reflected.

  Writing of the setting information to the memory card MC and creation of the setting information can be performed by a general-purpose personal computer by using dedicated software. Furthermore, the setting information can be transferred not only from the memory card MC to the flash memory 13 but also from the flash memory 13 to the memory card MC according to the operation of the operation input unit 3.

  Therefore, if the contractor creates setting information in advance in his / her office or the like and writes it in the memory card MC, the construction contractor performs various settings simply by mounting the memory card MC in the socket 4 of the monitoring control device 1 at the site. Therefore, the work efficiency of the setting work is remarkably improved as compared with the case where the setting work is performed by operating the monitoring control device 1 at the site. Further, for example, when a remote monitoring control system is constructed for each floor of a building, when a similar setting in which only a part is changed to a plurality of monitoring control devices 1 is performed, one monitoring control device If the setting of 1 is completed, there is an advantage that the setting work can be saved greatly by copying the setting information to another monitoring control apparatus 1 using the memory card MC.

  By the way, the monitoring control device 1 includes a substantially rectangular parallelepiped container 5 as shown in FIG. 4, and is attached to the wall in such a manner that the rear part of the container 5 is embedded in the wall in the same manner as the embedded wiring device. It is done. This monitoring control device 1 is detachably mounted on the front side of the embedded block 6 in such a manner that the rear portion is fixed to the wall so that the rear portion is embedded in the wall and the front portion protrudes forward from the wall surface. The panel block 7 is separated (see FIG. 6). Below, the structure of the monitoring control apparatus 1 is demonstrated by making the upper and lower sides and right and left in the state which attached the monitoring control apparatus 1 to the wall into upper and lower left and right.

  Here, the internal circuit of the monitoring control device 1 is divided into an embedded block 6 and a panel block 7. In the present embodiment, the power supply circuit 10 (see FIG. 3) for supplying DC power to the internal circuit and the communication circuit 11 are provided on the embedded block side, and other circuits (the display panel 2, the operation input unit 3, the main microcomputer). 12) is provided on the panel block 7 side.

  The embedded block 6 includes an embedded body 61 formed in a box shape having a rectangular opening on the front surface and an embedded cover 62 that is covered on the front surface of the embedded body 61. 60. A circuit board (not shown) on which various electrical components are mounted is housed in the embedded case 60. The embedded block 6 includes a power terminal portion (not shown) to which a power supply power supply line is connected and a signal terminal portion (not shown) to which the signal line Ls is connected on the back side.

  As shown in FIG. 5A, the panel block 7 includes a panel body 71 formed in a thin box shape having a rectangular opening on the front surface, and a panel cover 72 attached to the front surface of the panel body 71. And a circuit board 73 on which various electrical components such as the main microcomputer 12 are mounted is housed in the panel case 70. Further, the panel block 7 has a rectangular display window 74 penetrating a part of the front wall of the panel case 70, and includes the display panel 2 and the operation input unit 3 in the display window 74. Below the display window 74 on the front wall of the panel case 70, an operation unit 75 for operating a push button switch, which will be described later, is provided at the center in the left-right direction, and light from the LED is emitted to the left side of the operation unit 75. An LED window (not shown) for taking out is provided. At a position corresponding to the LED window in the panel case 70, an LED substrate 76 on which LEDs for status display are mounted is disposed. A protective membrane sheet 77 is attached to the entire front surface of the panel case 70. The LED substrate 76 is not limited to the lower left of the panel case 70, and may be disposed at any one of the four corners of the panel case 70, for example.

  Here, the monitoring control device 1 of the present embodiment suppresses the amount of protrusion of the container body 5 from the wall surface, and gives a sense of unity in appearance with the commonly used embedded wiring apparatus, In order to reduce the cost of the member used for attachment, the member is attached to the wall using an embedded box B1 (see FIG. 1) for an embedded wiring device installed in the wall. A rectangular construction hole H1 (see FIG. 1) is formed in a portion corresponding to the embedding box B1 in the wall material W1 (see FIG. 1) constituting the wall surface W0 (see FIG. 1), and this construction hole H1. A mounting hole for mounting the monitoring control device 1 is formed by the internal space of the embedded box B1.

  The embedding block 6 is attached to the embedding box B1 from the front through the construction hole H1, and the embedding case 60 is formed in a shape and size capable of accommodating the rear portion in the attachment hole. In the present embodiment, the embedded case 60 of the embedded block 6 is formed to have a size corresponding to the embedded box B1 in which up to two mounting frames (not shown) can be mounted. The single mounting frame here means a mounting frame that can be mounted by arranging three wiring devices with unit dimensions standardized by JIS in the width direction (vertical direction) for embedded wiring devices. A dimension in which two mounting frames for a single station are connected in the left-right direction is referred to as “double station”. That is, the embedding block 6 of the present embodiment is set to a size that can be attached to the double embedding box B1.

  More specifically, the embedded case 60 has a pair of attachment pieces 63 that are extended in a direction away from each of the end faces in the vertical direction. The pair of attachment pieces 63 are provided so as to protrude in the vertical direction from the front end portion of the embedded case 60 and are formed over substantially the entire length of the embedded case 60 in the left-right direction. Each mounting piece 63 has a plurality of box holes 64 (two here) through which mounting screws are inserted in the same manner as the mounting frame used when fixing the embedded wiring device to the embedded box B1. It is formed one by one. Note that a decorative plate (not shown) attached to cover the attachment piece 63 around the front end portion of the container 5 is screwed to the outside of the box hole 64 in the attachment piece 63 in the vertical direction. The plate mounting hole 65 is formed.

  Each of the embedded case 60 and the panel case 70 is provided with attachment means for coupling the panel block 7 to the embedded block 6 by engaging with each other. As shown in FIG. 6, the embedded case 60 has a fitting recess 66 on the front surface, and includes locking holes 67 provided on the left and right side surfaces of the fitting recess 66 as attachment means. The depth of the fitting recess 66 is set so that the bottom surface thereof is behind the wall surface W0, and two locking holes 67 are provided in parallel in the vertical direction.

  As shown in FIG. 6, the panel case 70 has a fitting protrusion 78 that protrudes on the back side and fits into the fitting recess 66, and is a locking piece provided on each of the left and right sides of the fitting protrusion 78. 79 is provided as attachment means. The fitting protrusion 78 is set to have a protruding dimension such that the front end surface (rear surface) is located behind the wall surface W0 when the panel block 7 is mounted on the embedded block 6. The locking piece 79 is provided at each position corresponding to the locking hole 67 in a state in which the fitting protrusion 78 is fitted in the fitting recess 66, and protrudes from the front end portion to the outside of the panel case 70. The locking claw 79a has a cantilever type snap fit shape that allows the locking claw 79a to be inserted into and removed from the locking hole 67.

  As a result, when the fitting protrusion 78 is fitted into the fitting recess 66, the locking piece 79 inserts the locking claw 79a provided at the tip thereof into the locking hole 67 as shown in FIG. Accordingly, the panel block 7 is mechanically coupled to the embedded block 6 by engaging with the locking hole 67. Here, in order to correspond to both when the panel block 7 is attached to the embedding block 6 and when the panel block 7 is removed from the embedding block 6, the locking claws 79 a have both side surfaces in the front-rear direction inclined. The cross section is formed in a substantially triangular shape. In addition, not only this structure but a locking piece may be provided on the embedded case 60 side, and a locking hole may be provided on the panel case 70 side.

  Here, the panel block 7 is formed so that the front-left dimension is substantially the same as the embedded block 6 and the vertical dimension is set slightly smaller than the embedded block 6. Therefore, the entire front surface of the embedded block 6 is not covered with the panel block 7 in a state in which the panel block 7 is mounted on the embedded block 6, and as shown in FIG. The portions where the holes 65 are formed are exposed on the upper and lower sides of the panel block 7. However, this exposed portion is hidden by attaching a decorative plate to the attachment piece 63. Here, the thickness dimension (the dimension in the front-rear direction) of the panel block 7 is set so that the protruding amount of the decorative plate and the panel block 7 from the wall surface W0 is substantially the same in a state where the decorative plate is mounted.

  The panel block 7 has a panel-side connector 80 (see FIG. 9) for connecting the embedded block 6 on the back side (the front end surface of the fitting protrusion 78). The embedded block 6 is a panel-side connector. The embedded connector 68 (see FIG. 6) connected to 80 is provided on the front side (the bottom surface of the fitting recess 66), and the panel side connector 80 and the embedded connector 68 are connected to each other, thereby The insert block 6 and the panel block 7 are electrically connected to each other. Here, at least one of the embedded-side connector 68 and the panel-side connector 80 is movable within a predetermined range within the plane along the front surface of the container 5 (displaceable vertically and horizontally). It consists of a stack connector. As a result, due to variations in the dimensions of the embedded case 60 and the panel case 70, variations in the mounting positions of components (connectors) on the circuit board, and the like, there is a relative relationship between the embedded connector 68 and the panel connector 80. Even if misalignment occurs, the embedded block 6 and the panel block 7 can be reliably connected.

  By the way, the socket 4 for the memory card MC is mounted on a circuit board 73 accommodated in the panel case 70 as shown in FIG. The socket 4 is mounted on the back side of the circuit board 73 at a position overlapping the display panel 2 in the front-rear direction. Thereby, compared with the structure which arranges the display panel 2 and the socket 4 side by side in the surface along the front surface of the container 5, it can be attached to the same container 5 dimension (this embodiment can be attached to a double embedded box. Size), the screen of the display panel 2 can be made as large as possible to make the screen easier to see.

  The socket 4 is arranged in such a manner that the opening is abutted against the insertion slot 81 so that the memory card MC is introduced from the insertion slot 81 opened in the side surface of the panel case 70. Here, the insertion port 81 is the left side surface (the right side surface when viewed from the back side) of the fitting projection 78 in the panel case 70, and as shown in FIG. 1, the embedded block 6 and the panel block 7. Is formed at a position that fits in the mounting hole (the construction hole H1 of the wall material W1 and the internal space of the embedding box B1) in a state of being mounted on the wall. Therefore, the memory card MC is attached / detached from the back side (fitting protrusion 78 side) of the panel block 7 with the panel block 7 removed from the embedded block 6. The insertion port 81 may be formed on any one of the peripheral surfaces intersecting the front surface of the body 5 (the right side surface, the upper surface, and the lower surface in addition to the left side surface), but the left side surface as in the present embodiment. The socket 4 can be arranged without interfering with a flexible cable (passing above the circuit board 73) for connecting the display panel 2 or the operation input unit 3 and the circuit board 73 by arranging the insertion port in the memory. The card MC can be easily attached and detached.

  According to this configuration, the insertion port 81 opens rearward (inside the wall) from the wall surface W0 in a state in which the container 5 is attached to the wall, and the memory card MC is normally attached to the wall 5 on the wall. Therefore, there is an advantage that it is possible to prevent the memory card MC from being removed due to mischief or the user from mistakenly inserting or removing the memory card MC. Moreover, since the socket 4 is provided in the panel block 7, when it is necessary to insert or remove the memory card MC, the panel block 7 is simply removed from the embedded block 6 without removing the embedded block 6 from the wall. The memory card MC can be inserted and removed.

  Here, since the display panel 2 is disposed in front of the socket 4, the wall surface W0 of the display panel 2 is compared with the case where the insertion port 81 is opened in a portion of the container 5 that protrudes forward from the wall surface W0. The amount of protrusion from the wall 5 can be kept small, and the amount of protrusion from the wall surface W0 can be kept small in the entire body 5. Note that the insertion port 81 does not need to be opened at a position where the entirety fits in the mounting hole, and at least a part thereof needs to be opened at a position where the insertion hole 81 fits within the mounting hole.

  Moreover, the recessed part 82 is formed in the approximate center part of the up-down direction in the left-right both sides | surfaces of the panel case 70, respectively. Accordingly, if the panel case 70 is grasped from both the left and right sides when the panel block 7 is removed from the embedded block 6, the panel case 70 can be easily grasped by hooking a finger on the concave portion 82. Work becomes easy.

  Further, a notch 69 opened forward is provided at a position corresponding to the recess 82 of the panel case 70 in the side wall of the fitting recess 66 of the embedded case 60. By providing this notch 69, the recess 82 is exposed through the notch 69 even when the panel block 7 is attached to the embedding block 6. When the panel case 70 is gripped from both the left and right sides, the fitting recess There is an advantage that the side wall of 66 does not get in the way and the panel case 70 can be easily grasped.

  By the way, in the present embodiment, the display panel 2 and the circuit board 73 housed in the panel case 70 are substantially the same as the front surface of the rear wall of the fitting protrusion 78 so as to be accommodated in the fitting protrusion 78 of the panel case 70. The display panel 2 covers substantially the entire front surface of the circuit board 73. Here, in order to enable the above-described push button switch SW to be operated from the front side of the container body 5 (which can be operated by pressing the operation section 75 provided on the front wall of the panel case 70), A tongue piece 73a is extended downward from this, and a push button switch SW is mounted on the front side of the tongue piece 73a. As a result, the tongue piece 73a protrudes downward from the lower surface of the fitting projection 78 as shown in FIG.

  Here, as shown in FIG. 10A, a through hole 83 penetrating in the front-rear direction is formed in a portion corresponding to the push button switch SW in the rear wall of the panel case 70, and a tongue piece 73 a is formed on the periphery of the through hole 83. The tongue piece 73a is exposed to the rear through the through hole 83 by standing the peripheral wall 84 so as to surround it. That is, the tongue piece 73 a forms a part of the outline of the panel block 7 together with the panel case 70. Thus, by exposing the back surface of the tongue piece 73 a from the panel case 70, the thickness dimension (the dimension in the front-rear direction) of the portion corresponding to the push button switch SW in the panel case 70 is equal to the thickness of the rear wall of the panel case 70. Can be small.

  Here, in order to avoid the tongue piece 73 a and the peripheral wall 84 from interfering with the attachment piece 63 of the embedded case 60 in a state where the panel block 7 is coupled to the embedded block 6, the tongue piece 73 a and the peripheral wall 84 of the attachment piece 63. A relief recess 63a (see FIG. 6) is formed in a portion corresponding to. The bottom surface of the relief recess 63a is abutted against the back surface of the tongue piece 73a in a state where the panel block 7 is mounted as shown in FIG. 10B, and the back surface of the tongue piece 73a when the tongue piece 73a is bent backward. It functions as a contact surface 63b that contacts with. That is, when the push button switch SW is pushed, the back surface of the tongue piece 73a comes into contact with the contact surface 63b, so that the external force acting on the push button switch SW can be received on the embedded block 6 side. The bending of the tongue piece 73a and the panel case 70 due to the operation of the SW can be suppressed.

  The push button switch SW is provided, for example, for forcibly invalidating the operation of the operation input unit 3. That is, when the pushbutton switch SW is pressed, the operation of the operation input unit 3 is invalidated thereafter, and it is possible to avoid erroneous operation of the operation input unit 3 when wiping the front surface of the panel block 7 or the like. . When the push button switch SW is pressed again in this state, the operation of the operation input unit 3 is valid thereafter.

  By the way, the monitoring control apparatus of the present invention is not limited to the configuration in which the socket 4 of the memory card MC is provided on the panel block 7 side as in the above-described embodiment, but the socket 4 is provided on the embedded block 6 side. May be. In this case, naturally, since the insertion slot 81 of the memory card MC is formed in the embedded case 60, it is necessary to remove the embedded block 6 from the wall when inserting or removing the memory card MC. Further, the embedded block 6 and the panel block 7 can be integrated so that only the panel block 7 cannot be removed. Even in this case, the insertion slot 81 of the memory card MC is formed at a position that fits in the attachment holes (the construction hole H1 of the wall material W1 and the internal space of the embedding box B1) in a state where the container 5 is attached to the wall.

  In the above-described embodiment, an example in which the memory card MC composed of an SD memory card is used as the external storage medium is shown. However, the present invention is not limited to this example, and other memory cards or memories such as USB memories are used as the external storage medium. May be.
