Abstract

PURPOSE:To miniaturize a power supply circuit by applying ON or OFF control of a load for each control system while giving a time difference with a delay means when a text of simultaneous control of the load is received. CONSTITUTION:When a communication means 35 of a terminal equipment 34 receives a control request of simultaneous ON control of loads 42-45, the request is sent to an arithmetic control means 30. The arithmetic control means 36 causes an exciting current to flow to an exciting circuit of a relay being a component of control means 38-41, the relay contact is closed to apply ON control to the loads 42-45. In this case, a delay means 37 is provided between the arithmetic control means 36 and the control means 38-41 and when a control request of simultaneous ON control reaches, the loads 42-45 are subjected to ON control with a time deviation one by one load. Thus, the time of simultaneous ON of the control means 38-41 is eliminated and the power supply circuit supplying the current is miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a transmission control device that controls a plurality of loads all at once through a single operation.

2. Description of the Related Art 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 method superimposes a communication signal voltage of a sufficiently higher frequency on the AC voltage of the power line to communicate between each device.This eliminates the need for special wiring for control, which reduces the time and effort associated with installation. It is characterized by low cost and low cost, and is becoming popular as a load control method in general households.

The configuration will be explained below with reference to FIG. In the figure, 1 is a commercial 100V power line, which is wired in a general household. 2 to 5 are terminal devices connected to power line 1, 6 to 9 are loads of terminal devices 2 to 5, and 10 to
Reference numeral 13 denotes local address setting means for the terminal devices 2 to 5.

14 to 17 are devices configured by combining loads 6 to 9 and terminal devices 2 to 5. The terminal devices 2 to 5 have a load state detection function, a load control function, a communication function, and a self-station address setting function, and the terminal devices 2 to 5 have a load state detection function, a load control function, a communication function, and a self-station address setting function.
It detects and controls the ON/OFF state of the power line 1 and communicates with other devices using the power line 1 as a transmission communication path. 18 is a control device, which is a type of device.

This is connected to the power line 1 and has a communication function, a control signal generation function, a monitor display function, a local station address setting function, and a partner station address setting function. Reference numeral 19 designates own station address setting means of the control device 18, reference numerals 20 to 23 designate partner station address setting means of the control device 18, and reference numerals 24 to 27 designate load control switches corresponding to the loads to be controlled. This load control switch 2
By pressing 4 to 27, the control device 18 sends an ON/OFF control command with its own station address attached to the terminal device killed by the partner station address setting means 20 to 23 corresponding to the switch. The terminal equipment detects and controls it, and as a result, sends the load status to the control equipment 18 with its own station address attached.

Upon receiving this, the control device 18 displays on the monitor display sections 28 to 31 the location corresponding to the transmitted own station address.

Problems to be Solved by the Invention In the above device, if a plurality of loads 6 to 9 can be controlled simultaneously with one terminal device by one operation of the control device 18, the operation will be simple and operation errors can be reduced. This has the advantage that the control time can be shortened compared to performing control individually. However, when controlling multiple loads at the same time with a single terminal device, there is a problem that the load on the power supply circuit increases and the terminal device becomes larger.

The present invention solves the above-mentioned conventional problems, and aims to reduce the load on the power supply circuit, downsize the terminal equipment, and control a plurality of loads at the same time.

Means for Solving the Problems In order to achieve the above object, the transmission control device of the present invention includes:
Multiple control means for controlling multiple loads and turning on each load
Alternatively, a delay means generates a delay time to add a time difference when controlling the OF FILL, and when a message for simultaneous load control is received, the delay means controls the ON or OFF control of each control system to make a time difference. The device is equipped with a terminal device having arithmetic and control means for adding and performing operations.

Effect According to 17 & above, even if multiple load control requests occur at the same time, the terminal devices control the loads one by one at different times.
Since N control is performed, a plurality of loads are always controlled with a slight delay in time, which reduces the load on the power supply circuit and allows the terminal equipment to be made smaller.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. Figures 1 and 2 show four loads being turned on by one terminal device.
A configuration diagram for /OFF control is shown. Commercial 100V
The power line 32 serves as a transmission channel as well as a power supply. The control device 33 is connected to the commercial 100V power line 32, and has a function of outputting a control signal to the power line 32 when a control request is generated by a user's operation or the like.

The terminal device 34 is also connected to the power line 32, and loads 42 to 45 to be controlled are connected thereto. load 4
2 to 45 are electrical appliances such as lighting. The terminal device 34 is composed of a communication stage 35, an arithmetic control stage 36, a delay means 37, and the like. The communication means 35 of the terminal device 34 is the power line 32
It receives a communication signal from and sends it to the calculation control means 36, and also sends the communication signal generated by the calculation control means 36 to the power line 32. The arithmetic control means 36 performs arithmetic control based on a predetermined procedure, and can be realized by, for example, a microcomputer. The control means 38-41 are for ON/OFF control of the loads 42-45, and can be realized by relays or the like.

Here, if the communication means 35 of the terminal device 34 receives a control request to turn ON the loads 42 to 45 all at once, it sends this to the arithmetic control means 36 . In response to this simultaneous load ON control request, the arithmetic control means 36 causes excitation currents 11, 12, 13, and I4 to flow through the excitation circuits of the relays constituting the control means 38 to 41.

Then, each relay contact is closed and the loads 42 to 45 are controlled to be turned on. At that time, the calculation control means 36 and the control means 38 to
Since a delay means 37 is provided between 4l and 4l, they are turned on all at once.
When a control request is received, the loads 42 to 45 are shifted one by one by a certain period of time and turned on. This eliminates the time when the control means 38 to 41 are ON at the same time, and the power supply circuit (not shown) that supplies the current can be downsized.

Further, the terminal equipment 34 and the control means 38 to 41 are housed in a free box 46. The delay means 37 consists of a delay circuit and a load control command receiving circuit (not shown).

Next, the operation of the thousand delay stages 37 will be explained. FIG. 3 is a flowchart of this delay stage 37. First, the arithmetic control means 36 checks whether the delay circuit is at "0". This is because the fact that the delay circuit is not "0" indicates that a load control command is being output, and in that case, the value of the delay circuit is set to "-1" and the next operation is started. Next, the arithmetic control stage 36 checks whether the load control command reception circuit is ON, and if it is ON, sets a delay time "T" in the delay circuit and executes output processing. If it is OFF, output processing is executed without passing through the delay circuit. FIG. 4 is a time chart showing the operation of the terminal equipment. As is clear from this figure, when a signal to turn on the loads 42 to 45 all at once comes, each of the loads 42 to 45 turns on at a lag of a certain period of time, thereby making it possible to avoid increasing the size of the terminal equipment.

Effects of the Invention With the transmission control device of the present invention, even in the case of simultaneous ON control of multiple loads using a transmission communication channel, all loads can be turned ON.
Since the times at which the two relays are connected are always different, the excitation current flows through each relay in sequence. As a result, the power supply circuit becomes smaller and the terminal equipment can be made smaller, which has a great practical effect.
