Description

[Detailed description of the invention]

The present invention enables a central device to monitor and monitor devices connected to a plurality of terminal devices arranged in a relatively narrow area.
Regarding the remote monitoring and control device to be controlled, in particular, since the object to be monitored and controlled is relatively small, the configuration of the monitoring and control system is simplified and the functions are made flexible. Generally, in a relatively narrow area such as a small-to-medium-sized store or a general household, various devices distributed over long distances are used as loads and their status is monitored using various detectors for purposes such as energy conservation, crime prevention, and disaster prevention. At the same time, regarding remote monitoring and control equipment that is centrally controlled, since the subject of monitoring and control is small-scale,
It is necessary to simplify the configuration of the device so that it can be installed at low cost, and also to be able to use a variety of functions flexibly. On the other hand, in what is considered to be a typical example of this type of conventional remote monitoring and control device, the following various functions are centrally performed by a main control device. (1) Centralized remote control of the load using the selector switch (2) Centralized remote monitoring of the load using the light-emitting display attached to the selector switch (3) Programmable batch remote control using the lifestyle pattern switch (4) Occurrence of fire, gas leak, etc. Disaster prevention through notifications, crime prevention through intruder detection notifications, and display on monitors of locations where accidents have occurred (5) Calls between rooms (6) Notification of visitors using intercoms and monitor television cameras (7) Using clocks, timers, etc. Various Notices (8) Various Numerical Calculations However, the main control device that performs the various functions mentioned above in this conventional device has a complicated configuration with a number of units, so it cannot help but be expensive. In addition, in order to connect the main control device and various controlled devices via a line and operate them according to commands from the main control device, the channel number of the line must be set for each terminal where these devices are installed. A numerical setting switch is required to set the channel number, and in order to mutually transmit operation commands from the main controller and information from each terminal, it is necessary to specify the channel number each time. Moreover, in the past, channel numbers used for each function were fixed. For example, the channel number set for a terminal to perform alarm functions for disaster prevention and crime prevention was 6 bits. Because channel numbers are assigned using binary codes, the number of various detectors that can be installed for disaster prevention and crime prevention is limited, and the circuit configuration for setting channel numbers is extremely complicated. . That is, an extremely large number of switches are arranged on the back of the above-mentioned alarm unit, for example,
To detect intruders, a total of 6 detectors are distributed, 3 on 2 channels, and each is equipped with 10 switches to display the location of the intruder on the monitor television. It requires 60 switches just to function.
In addition, the display of alarm occurrence locations is limited to one location at a time, and it is impossible to display alarms at the same time when alarms occur in multiple locations. Can only display individual locations. The same applies to selector switches for individually remotely controlling various types of load equipment; the channel number is fixed for each selector switch, and three load equipment are connected to each channel, so one There are three selector switches per channel. Therefore, in standard conventional equipment, three load devices are connected to each terminal of 12 channels, so a total of 36 selector switches are provided, and terminal control with different configurations for each function is required. Since the devices were determined, it was necessary to manufacture each type of terminal control device. As mentioned above, this type of conventional remote monitoring and control device has various drawbacks, but the drawbacks can be summarized as follows. (1) In order to realize a wide variety of functions, it is necessary to provide a variety of different units for each function in a main control device, which increases the scale of the main control device.
The cost will be high. (2) The configuration of the terminal devices used differs for each function, and it is necessary to manufacture many types of terminal devices to configure the system. (3) The channel number and number of channels are fixed for each function, and therefore the number of terminals that can be connected to the line is limited, or the large-scale There may be unused parts of the equipment, which is uneconomical. (4) There is little flexibility in system functions, such as the display of alarm occurrence locations being predetermined.
Further, it is necessary to provide a large number of switches individually to display the location where the alarm occurs. In addition to the various drawbacks mentioned above, the conventional device also has the following drawbacks. In other words, for example, when properly controlling air conditioning equipment, which is an important element for achieving energy savings and comfort, automatic operation using temperature detectors is required.
Conventional devices do not have such functions, and in order to newly add automatic driving functions to conventional devices, a dedicated terminal device is naturally required, which leads to the various disadvantages (1) to (4) mentioned above. The same applies to the function of automatically controlling the start and stop of load equipment using a timer device. It is an object of the present invention to eliminate the above-mentioned drawbacks of the conventional technology, to improve the operation mode of the main control device installed in the center station, to significantly reduce its scale compared to the conventional technology, and to provide abundant functions with a simple configuration. To provide a remote monitoring and control device capable of realizing the above, and further reducing the types of control devices installed in a terminal station significantly compared to conventional ones, and configuring a system with a significantly high degree of freedom. It is in. In order to achieve this object, the present invention connects a center device and a plurality of terminal devices via lines, and controls at least one device connected to each terminal device by commands from the center device. The center device of the remote monitoring and control device, which monitors the device using the center device based on information from the device, has multiple pairs of terminal keys and displays, and one pair of terminal keys and display devices is used to connect any device and monitor.・Function keys including program keys as a means of instructing the center device to program to assign control functions, and the channel number of the terminal device to which one device is connected to be assigned to the above pair of terminal keys/displays. , Numeric keys are provided as a means of inputting a port number indicating the port of the terminal device to which one of the above devices is connected, and a function number indicating the monitoring/control function to be assigned, and programming and one terminal are provided. Programming that assigns any device or monitoring/control function to a terminal key/display pair by pressing the key and then inputting the channel number, port number, and function number from the numeric keys is possible. Once programmed, in response to the press of a terminal key, a transmission containing an address signal corresponding to the channel number of the terminal device to which the device assigned to this terminal key/display pair is connected. It is designed to automatically create and output signals. The present invention will be explained in detail below with reference to the drawings. First, FIG. 1 shows a schematic configuration of the remote monitoring and control device of the present invention. In the illustrated configuration, the center device
CNT and each terminal device T-1, T-2, T-3,...
... are connected to each other by a three-wire line for supplying power and transmitting signals, and any number of terminal devices can be connected in parallel. Remote control from the center device CNT is possible by pressing a master key arranged as will be described later with reference to FIG. In principle, any number of terminal devices can be connected as described above, but there are restrictions on the number of channel number setting switches and signal transmission speed, so in the example shown, up to 16 terminals can be connected. Allows parallel connection. Signal transmission in the above configuration is performed by a time division mass transmission method as shown in FIG.
Although the configuration is the same as in the conventional configuration, the amount of data that can be transmitted is much larger in the illustrated example because the functions of the terminal device are much richer than in the past. In order to automatically control air conditioning equipment using a terminal device, the amount of analog information such as the detected temperature of a temperature sensor connected to a terminal device is transmitted by analog-to-digital conversion.
The amount of data transmitted from terminal devices to center devices is increasing. The center device CNT and each terminal device T-1, T-2, T-3, in the configuration shown in the first diagram.
An example of the structure of data mutually transmitted between the two is shown in FIG. In the illustrated example, the command and control data transmitted from the center device to the terminal device consist of 16 bits as shown in the figure. Note that the information data transmitted from the terminal device to the center device is as shown in the diagram.
It consists of 52 bits, and is prioritized data from a terminal device immediately after an interrupt transmission request from the terminal device where an alarming accident has occurred, or an operation such as a command to start/stop load equipment from the center station. Transmission formats other than those shown in FIGS. 2 and 3 can also be used, and the data transmission time can also be extended when additional terminal devices are added in the future. Next, FIG. 4 shows an example of the configuration of a terminal device in the remote monitoring and control device of the present invention. In the illustrated configuration, a control microprocessor consisting of an inexpensive one-chip microcomputer is used to simplify the circuit configuration and to simultaneously connect and control various load sensors with various functions to a single terminal device. It is mainly configured with a controller, and can handle various complex functions such as analog-to-digital conversion of analog data such as temperature sensors, data processing of channel address setting switches, and time division multiplex transmission. It can be provided at low cost using a circuit device. That is, the control microprocessor 4 is supplied with power from the three-wire transmission line 1 via the stabilized power supply 3, and also sends and receives data to and from the center device via the transmitter/receiver circuit 2. An address setting switch 5 that sets the identification address of the terminal in a bit binary code, a detector 6 that generates various alarms, and a load drive relay contact 9 that is driven by a load drive relay 8 via a transistor amplifier 7. ,

The functions that can be performed by the circuit configuration as described above are as follows. (1) Start/stop control of four load devices using load drive relay contacts 9 (2) Analog signals from four analog sensors 13
Analog/digital conversion of data and input processing (3) Inputs to the four alarm generating detectors 6 (4) Inputs to the four terminal information switches 14 The various functions described above are performed as follows. That is, function (1) is performed by opening and closing the load driving relay contact 9 using the load driving relay 8.
Function (2) converts analog data from various analog sensors 13 into digital data via an analog-to-digital converter 10 consisting of a digital-to-analog converter 11 and a comparator 12, and sends the digital data to the control microprocessor 4. Functions (3) and (4) are performed by sending the settings of the alarm generation detector 6 and terminal information setting switch 14 to the control microprocessor 4, respectively. In addition, to set the channel number as the identification address of the terminal, use the address setting switch 5 to set 2 ⁴ = 16 binary codes using on/off combinations of the four switches. Let's do it. In addition, port numbers of the microprocessor 4 to which components such as load devices are connected are assigned to each function in order to perform each of the above-mentioned functions (1) to (4). are assigned to the on/off control of the drive relay 8 and correspond to the relay outputs X1 to X4 in the data shown in the third diagram, and port numbers 5 to 8 are assigned to the analog sensor 13 and correspond to the digital data in the data shown in the third diagram. Corresponding to S1 to S4, port numbers 9 to 12 are assigned to the alarm generation detector 6 and correspond to alarm data A1 to A4 in the data shown in the third figure, and port numbers 13 to 16 are assigned to the terminal information switch 14. Port C1 shown in FIG.
- Corresponds to C4. Next, FIG. 5 shows an example of the configuration and arrangement of the operation section of the center device in the remote monitoring and control device of the present invention.
In the illustrated configuration, operations for providing various functions of the simplified remote monitoring and control device, which is a feature of the present invention, are not divided into a plurality of units according to function as in conventional devices. Everything is concentrated in this control section. For example, to explain the case where the operation unit with the configuration shown in the figure is used in a general home, each terminal device is appropriately placed in each room, and each terminal device can be remotely controlled or connected to a desired load such as a light or air conditioner. Furthermore, temperature sensors and the like can be connected to automatically control air conditioning equipment and the like. At the same time, an intruder detector,
Alternatively, connect fire detectors such as heat detectors and smoke detectors, gas leak detectors, etc. as necessary. In addition, since each terminal device must have its own channel address, it is necessary to set the channel address from 0 to
Assign 16 channel numbers. Next, in the operation section having the configuration shown in FIG. Must be programmed. For example, a program for remotely controlling a light connected to the port numbered "1" of the control microprocessor 4 in the terminal device with the channel number "0" using the terminal key numbered "1" is as follows: The procedure is as follows. Step (i) Press the program key among the function keys 30. At this time, the program lamp in the function display lamp 29 lights up.
All digital displays 28 display "-". Step (ii) Press the “1” terminal key.
At this time, the terminal operation lamp corresponding to the terminal key No. 1 blinks, indicating that programming is in progress. Step (iii) Using the numerical keys 31, successively key in the channel number "00", port number "01", and function number "10" indicating the remote control function of the terminal device.
At that time, the digital display 28 shows “00−01−
10" is displayed. If you key in by mistake, press the clear key and key in again sequentially starting from the channel number. Step (iv) Next, press the terminal key numbered "1" again. The terminal operation lamp corresponding to the terminal key “1” goes out, the program is completed, and the digital display 28
are all displayed as "-" again. Step (v) When the programs of all terminal devices are completed by the operations in steps (ii) to (iv), the program key is pressed again to turn off the program lamp and change the digital display 28 to a clock display. The above is the programming procedure. In step (ii) above, instead of pressing the terminal key number "1", it is also possible to input the terminal key number "1" using the numeric keys 31. In addition to remote control, the functions of the terminal device include a temperature sensor alarm detector as mentioned above, and the function numbers for each are determined as shown in Table 1. The function number must be programmed correctly. In the above example, in the case of programming by mistake, for example, even if the intruder detector's function number "31" is input to the port number "1" of the function of the load device to be turned on/off, the program is not programmed. are doing. In the above example, prior to programming the terminal device, it is necessary to set the clock of the center device for the on/off timer function.

[Table] Once the function number of the terminal device corresponding to the pressed terminal key is programmed as described above, the terminal key and terminal operation lamp can be operated and displayed according to that function number. becomes. As in the above example, if you assign the light connected to channel number "0" and port number "1" to terminal key "1", when the terminal operation lamp "1" is off, When the terminal key numbered "1" is pressed, the center device transmits the channel number "0", port number "1" of the terminal device assigned to this terminal key "1", and the function number corresponding to the remote control of the light. From "10", automatically create terminal address data such as [000000], relay output data [1***], and mode identification code data [000] in the transmission data configuration shown in Figure 3. , these data are concentrated and output as transmission data from the center device to the terminal device. The * marks in the relay output data in this example correspond to the other ports (port number "1" and the X1 bit of the relay output in the transmission data in Figure 3) when the terminal key is pressed. Each bit of relay output
2, X3, and X4 are respectively associated with each other. ) indicates that it takes 1 or 0 depending on the operating state of the device connected to it. The terminal device with channel number "0" detects that the transmission is addressed to itself from the terminal address [000000] in this transmission data, receives the transmission data following this terminal address, and sends it to the port with number "1". Activate the connected relay. As a result, the electric light is turned on, and the terminal operation lamp numbered "1" in the center device is also turned on. Then again, “1”
When the numbered terminal key is pressed, the light is turned off and the terminal operation lamp numbered "1" is also turned off. In this way, remote control from the center device becomes possible, and the on/off status of the lights can be monitored. Furthermore, if the channel number and port number of the terminal device equipped with an intruder detector are assigned to the terminal key "2", when the intruder detector is activated, " Intrusion”
The lamp lights up to notify that an alarm against an intruder has occurred, and at the same time, the terminal display lamp 25 numbered "2" lights up to notify the location where the alarm has occurred. It is preferable to clearly indicate the specific location where the intruder detector is installed in the blank space above the terminal operation lamp numbered "2". In any case, the 26 terminal keys and terminal operation lamps in the center device can correspond to load equipment with any function, and the desired configuration can be arranged for ease of use when programming the terminal device. It is preferable to clearly indicate the function and installation location in the blank space above each terminal operation lamp. As explained above, in the remote monitoring and control device of the present invention, the center device includes a plurality of pairs of terminal keys and displays, and one pair of terminal keys and displays has arbitrary equipment and monitoring/control functions. a function key including a program key as a means of instructing the center device to program a program to be assigned; a channel number of a terminal device connected to one device to be assigned to the pair of terminal keys/display; Numeric keys are provided as a means of inputting the port number indicating the port of the terminal device to which the device is connected, and the function number indicating the monitoring/control function to be assigned, and the program key and one terminal key are connected to each other. Following the press,
By inputting the channel number, port number data, and function number from the numeric keys, programming is performed to assign arbitrary equipment and monitoring/control functions to one terminal key/display pair.
Moreover, once programmed, in response to the press of a terminal key, transmission data including an address signal corresponding to the channel number of the terminal device to which the device assigned to this terminal key/display pair is connected is transmitted. automatically create and output,
By doing so, the following remarkable effects can be obtained. (1) Since the execution and monitoring of various functions can be assigned to a pair of terminal keys and indicators, there is no need to provide the same number of terminal key/indicator pairs as the total number of functions of the device on the center unit, and The configuration is extremely simple and inexpensive. (2) Since each terminal device can be made multi-functional and its types can be standardized, the manufacturing cost of the terminal devices can be reduced. (3) Since the channel numbers and number of channels can be freely allocated by function, there will be no excess or deficiency in the equipment of the terminal equipment or center equipment. (4) The display of the occurrence location of alarms and terminal information can be set arbitrarily, and there is no need to provide an independent switch for displaying the occurrence location.
