Thus, the common processing is applied to apply immediate control of the load and timer control of the load. Thus, the processing is simplified and the command system is unified.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a timer reservation device used for communication between distributed devices.

Conventional technology Transmission control has traditionally involved connecting each device with an electrical communication network and transmitting control signals to each other for the purpose of centrally controlling multiple devices or monitoring the current status of the device. method is used. - For example, there is a method of using a commercial 100V power line as a transmission communication channel to control the load in a general household. This superimposes a communication signal voltage of a sufficiently higher frequency on the AC voltage of the commercial 100Vt line of force to communicate between each device, and since special wiring for control is not required, installation is required. It has the characteristic that it requires less effort and cost. In this case, the equipment is the load to be controlled, the load state detection function that detects the state of the load, and whether the load is energized (hereinafter referred to as ON) or de-energized (
This refers to a combination of a load control function that controls the load (hereinafter referred to as OFF) and a communication function that transmits and receives control signals to and from other devices. In addition, as another type of device, there is a communication function that sends and receives control signals to and from each device, a control signal generation function that generates 0N10FF control signals to be transmitted to each device, and a display that indicates whether each device is in the ON or OFF state. There is a control device that has a monitor display function and a local address setting function.

A transmission control method using a commercial 100V power line will be described below with reference to the drawings. FIG. 3 is a block diagram of a conventional transmission control method using a power line. 1 is commercial 100
This is a V power line and is found in a typical household. The devices 8 and 9 are a combination of loads 4 and 5 and terminal devices 2 and 3, respectively, and are connected to the power line 1, respectively.

As mentioned above, the terminal devices 2 and 3 have a load state detection function, a load control function, a communication function, and a local address setting function.
It has the function of detecting and controlling F and communicating with other devices using the power line 1 as a transmission communication path. In order to ensure this communication, each device has its own address set by the own address setting means 6 and 7. Further, the control device IO is a type of device, and is connected to the power line 1, and has a communication function, a control signal generation function, a monitor display function, a self-station address setting function, and a partner-station address setting function as described above. 1
1 is a local address setting means. Then, by pressing the load control switch 16 to 19 corresponding to the load to be controlled, the control device 10 sends the control command of 0N10FF to the terminal device set by the partner station address setting means 12 to 15 corresponding to that switch. A signal indicating the address is added and transmitted. Each of the terminal devices 2 and 3 detects this signal, and sends the signal indicating the status of the loads 4 and 5 to the control device 10 with its own station address attached thereto. In response to this, the control device 10 displays on the monitor the portion of the received signal that corresponds to its own station address. Through the series of operations described above, the load condition can be controlled and remonitored as desired.

Furthermore, a case may be considered in which timer reservation settings are made from the control device 10 to the terminal devices 2 and 3. At that time, the timer time set by the timer reservation setting function 24 in the control device 10 and the timer control contents are combined and transmitted to the terminal devices 2 and 3. This signal is sent to terminal devices 2 and 3.
is received and when the time set by the timer time functions 25 and 26 of the terminal devices 2 and 3 arrives, the load 4 and the
Control 5.

Problems to be Solved by the Invention However, in the above configuration, there is a difference between when the load is immediately controlled by the load control switch in the control device and when the same device is timer controlled by the timer reservation setting function in the control device. This will result in an increase in command definitions and processing. In addition, timer time data is very complex with 0N10FF times (year, month, day, hour, minute, and day), and is often impossible to express in one data transmission message, and usually shows a series of connections. It has the structure of a message (Begin-Data-End). Moreover, since the timer reservation setting does not differ in that it controls the load, it is considered that the control content modifies the timer time data.

Therefore, in order to solve the above-mentioned conventional problems, the present invention provides a message structure that includes information to distinguish between timer control and immediate control in the load control message, and incorporates this into the timer reservation setting En.
This is used as a d message (the Begin message and the Data message are timer time data messages) to simplify not only the processing but also the command system.

Means for Solving the Problems In order to achieve the above object, the timer reservation device of the present invention includes a terminal device that controls a load based on a received message, and a control device that transmits a message for controlling the terminal device. , and a transmission communication path for transmitting data between the terminal device and the Ruri control device, and the 1til control device transmits a timer time data message for controlling the timer city II of the terminal device, and a timer time data telegram for controlling the timer city II of the terminal device. A data transmission message creation means for creating a load control message containing information that distinguishes whether to perform timer control of a terminal device or to immediately control the terminal device in combination with the message; and a message created by the data transmission message creation device. The terminal device includes a receiving device that receives a data transmission message on the transmission communication path transmitted from the control device, a load control device that controls the load, and a terminal device that counts time and determines a predetermined time. If the data transmission message received by the receiving means is a timer time data message, outputs the timer time data to the time measurement means, and if the data transmission message received by the receiving device is a timer time data message, outputs the timer time data to the time measurement device, and if it is a load control message, the load control device outputs a signal to the load control device. The configuration includes a data transmission message determining means for outputting information on whether the control is timer control or immediate control and load control contents to the means.

With this configuration, when a terminal device is to be immediately controlled by the control device, the data transmission creating means creates a load control message with information for immediate sub-control, and the transmitting means transmits this to the transmission path. The terminal device receives the message on the transmission route by the receiving means, and the data transmission message determining means determines that immediate control is required and instructs the load control means to control the content. The load control means receives this and controls the load according to the contents of the control instruction.

When a terminal device is controlled by a timer from a system management device, a data transmission creating means creates a load control telegram having a timer time data telegram and a timer control information, and a transmitting means transmits this to the transmission path. The terminal equipment receives the message on the transmission route by the receiving means, and the data transmission message determining means determines that the timer control is required, and instructs the load control means to control the contents, and at the same time passes the timer time data to the clock means. The timer receives this and outputs it to the load control means when the current time reaches the timer time.

The load control means receives these information, and when the timer time comes, the load is controlled according to the contents of the control instructions.

On the other hand, the terminal device 28 is connected to the commercial 100V power line 27.
The receiving means 36 receives the above message, the own station address setting means 37 determines the own station, and the own station address setting means 37 determines whether the received message is addressed to the own station, and then the message is sent to the timer. In the case of a time data message, timer time data is output to the clock means 38, and in the case of a load m'1ga message, information on whether timer control or immediate control and load control contents are output to the load control means 39.Data transmission message judgment means 40, and timekeeping means 38 for outputting a signal to the load control means when the current time and timer time data become the same.
