Abstract

PURPOSE:To register a device connected to a system from a main controller at an optional time, by providing a register key on an operation part for the purpose of recognizing and registering a device connected to an information line. CONSTITUTION:When an oil FF hot blast heater is connected as an air conditioner while the system is operated, it is necessary to register this connection to a main controller 1. In this case, when a register key 9 provided in an operation part 5 is inputted, a register request to each device is transmitted by the register command of the polling transmission control system. It is necessary that each device responds with its attributes (the oil FF hot blast heater or the like) in accordance with the request of the controller 1 if it is connected to the system. After the request for registering all devices is terminated, a normal operation is possible. When the controller 1 is set to the register mode, all key inputs are made ineffective.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a home control system for centrally controlling household electrical appliances.

Conventional configurations and their problems In the case of centralized controllers for household electrical appliances, it is necessary to recognize what kind of devices are connected and register them with the central controller. Conventionally, the following two methods have been adopted. was.

■When the power is turned on to the entire system, information for recognition and registration is transmitted from the central controller to each device.

■Equip each device with a means of registration to the central controller.

However, such a system must be kept in operation at all times, and cannot be turned on and off each time a device is connected, unlike the former method. Furthermore, the latter method has the problem of requiring all connected devices to have some kind of registration means.

OBJECT OF THE INVENTION The present invention solves such conventional problems.
The purpose is to provide a registration means for arbitrary registration and recognition.

Structure of the Invention In order to achieve this object, the present invention has an operation section for making various settings, a main controller having a CRT display section, and each household device are connected by the same information line, and a polling system is provided. Transmission control method The Oturu home control system recognizes and recognizes devices connected to one information line.
In order to register, the operation unit is configured to have a registration key.

With this configuration, if you input this registration key at any time, registration information is transmitted to each device via the information line using the polling transmission control method, and the device that receives the information sends the information to the main controller. It transmits information about what the device is and registers the device with the main controller.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. In Fig. 1, a main controller 1 is connected to a household device 3 via an information line 2 (here, a coaxial cable).
(In this case, air conditioners and water heaters) are connected to each room. FIG. 2 is a front view of the main controller 1, where 4 is a CRT display section and 6 is an operating section. Operation unit 6

,．． A 0LOOK key 12 is provided.

13 is a clock display section, which uses an LED here. How to operate the operation unit will be explained using one example.

First, press the "Cooling" key among the function selection keys 6, and then press the "Living room j" key among the one place selection keys 7. It will look like Figure 3. Here, by setting the cooling start time, cooling temperature, etc. using the -numeric setting key 8 and setting the setting ON key 1o, when the set cooling start time comes, the air conditioner 3 in the "living room" Cooling start information and cooling temperature information are transmitted to the air conditioner (in this case, the air conditioner).

The rcLOcKj key 12 is used when adjusting the clock tower or setting the clock.
The settings are displayed in D using the numerical setting key 8.

Now, if a petroleum FF warm air fan is connected as an air conditioning device while the system is operating, it is necessary to register in the main controller 1 that this device is connected to the system. At that time, when the registration key 9 of the operation unit 6 is input, a registration request to each device is transmitted by a registration command of the polling transmission control method described later. If each device is connected to the system, its attributes (air conditioner or oil
F hot air fan, etc. (classified by code) must be answered. Once the registration request is completed for all devices, normal operations are possible again. here,
When the main controller is in 1-boat registration mode, all key manual input is disabled.Next, we will explain the transmission control in this system. The communication method is a two-wire half-duplex communication method, and a polling transmission control method is used for transmission control.

Transmission control is performed using the main controller 1 as a master station and each device connected via an information line (coaxial cable in this case) 2 as a slave station. The situation is shown in FIG. 4 and FIG. 6. FIG. 4 shows the data structure of transmission information, and FIG. 4(a) is its basic form. Each transmission information includes a SYN code for synchronization, each device (

The data information shown in Figure (C) must be transmitted to the master station. This includes an attribute code that indicates what type of device the slave station is.Also, if the slave station cannot receive data correctly, a NACK command (
It is necessary to return the data (FIG. 4(d)) to the master station. This situation is

In response, the slave station needs to send the ACK2 command shown in Figure 4 (f''l).Also, if the master station requests the slave station to send data, the slave station must send the ACK2 command shown in Figure 4 (g). Send the ENQ3 command (reception command) to the slave station.ACKl, 2 used here
A command is used to notify the master station that data has been received correctly, whereas a NACK command is used to detect an error in the data and request the data from the master station again. It is something. This situation is shown in FIGS. 5(b) and (0). In this way, the above-described transmission control method in which the master station has priority in determining which slave station to communicate with is referred to herein as a polling transmission control method.
