Description

Electrical connector for realizing controlled device address assignment

The present invention relates to an electrical connector between a smart device and a power source in a smart home network and a communication method thereof, and more particularly to an electrical connector having a wireless communication interface and a communication method therefor in a smart home network environment. m

Currently, in the smart home network cabling, home network cabling has always been a problem to be solved due to the diversity of smart home appliances and the inconvenience of home wiring. The use of power line networking is originally the most convenient, but its adapter is more expensive, and the interference is serious, and the network of multiple homes is easy to crosstalk, thus limiting its application; using wireless network because of signal attenuation and wall blocking and bandwidth is not Stable, coupled with a slightly higher cost, is also difficult to widely popularize; Ethernet, CEbus and other buses are very troublesome wiring, which will lead to smart cables everywhere in the smart home, especially the already built housing, there will be a large number of network cables needed Rearranging, it is very troublesome.

The Chinese Patent Application No. 2008101990766, "An Electrical Connector", discloses an electrical connector with a wireless communication coupling port for network communication by means of a wireless communication coupling port while being electrically connected. The structure is as shown in FIG. 1. The plug post 7 of the plug 6 is connected to the electric device through a power line, and the wireless communication coupling port 8 of the plug port is provided with the communication module 9 and is connected to the control circuit of the electric device through the communication line. Pick up. Correspondingly, the conductive plug slot 4 of the socket 1 is connected to the mains, and the coupling port 5 of the wireless communication is provided with the communication module 10 and is connected to other devices (such as a computer server:) through a communication line. The plug 6 of the electric device is inserted into the plug hole 2 of the socket to realize the connection with the mains, and the electric device is turned on to start working, and the wireless communication coupling ports 5 and 8 are closely aligned, and are in communication. Communication is established under the driving of modules 9, 10.

However, this patent application does not disclose how to pass the specific communication process between the two communication modules, and between the communication module and other devices, the communication module and the powered device, and in particular, the address allocation process of the powered device is not specifically described. On the other hand, there are two main ways for an intelligent device to allocate addresses in the prior art: one is to assign an IP address to a smart device by DHCP (Dynamic Host Configuration Protocol), and the other is to directly use the smart gateway as a smart device. Assign a specific non-IP address. At present, the smart home field is more about adopting a method of directly assigning a specific non-IP address to a smart device. For example, DALI, CEBUS, and EIB standards, which are common in the smart home field, each define a proprietary protocol for device address format and address allocation method. However, the address allocation process of these protocols is complicated and requires smart devices to meet higher conditions. For example, the DALI protocol requires that each smart device on the same bus can generate different 24-bit random numbers. Summary of the invention

In view of the disadvantages of the prior art, the present invention provides an electrical connector that implements address assignment of a controlled device, including:

Socket and plug;

The socket includes a first processing module and a first wireless interface connected to the first processing module; the plug includes a second processing module and a second wireless interface connected to the second processing module; wireless between the first and second wireless interfaces Even the line communication;

The first processing module is connected to the control device by using the first wired interface or the third wireless interface, and the second processing module is connected to the controlled device by using the second wired interface or the fourth wireless interface;

The first processing module includes a first receiving module, a first sending module, a third receiving module, and a storage module, and the second processing module includes a second receiving module and a second sending module.

Further, the first receiving module is configured to receive the fixed address of the controlled device sent by the second processing module, the first sending module is configured to send the fixed address to the control device, and the third receiving module is configured to receive the Controls the dynamic address of the device and stores the dynamic address in the storage module.

Figure 5 shows the structure of the electrical connector module used in the present application.

FIG. 2 shows the specific structure of the Zhihui Marriage Network disclosed by the present invention, which mainly includes a digital home intelligent gateway inside the home. The mesh is connected to the bus switch, the Ethernet bus, and the 485 bus to connect various intelligent devices.

Figure 3 shows the device address structure in the disclosed Zhihui grafting system of the present invention. The device address is divided into a fixed address and a dynamic id address. The fixed address is solidified in the memory chip before the device leaves the factory, and the dynamic id address is the address assigned by the gateway as the communication of the node after the device accesses the bus for the first time.

The device fixed address is the unique ID number of each device, which can be composed of one or several of the device type, the barcode of the device, the batch code of the device, and the serial number of the device. This addressing method can guarantee the uniqueness of each device in different scenarios.

In the first embodiment, if the controlled device has only one unique one in the smart home network, for example, the gate access control. Then the device fixed address can only include the device type code and the barcode of the device.

In the second embodiment, if the controlled device includes a plurality of devices, but can be uniquely determined according to the barcode and the batch code of the controlled device, for example, a device of the same type that is gradually added, the device fixed address may only include a «type code, The barcode and the equipment of the device are under-coded.

In the third embodiment, the device fixed address may also include only the device type code, the barcode of the device, and the device serial number.

In the fourth embodiment, if the controlled device cannot be uniquely determined by the lot and the barcode, such as a lighting device. Then the device fixed address may include the device type code, the device's barcode and the device batch code, and the device serial number.

In the case of the fourth embodiment, the device fixed address is composed of 17 bytes, wherein the first byte is set to «type, then 12 bytes is the barcode of the device, and then the batch number of the 2-byte device is added. The last two bytes represent the serial number of the device. Of course, you can assign different fields according to specific needs. Different number of bytes. In the first two embodiments, the bytes representing the corresponding class can be removed, thereby constituting a shorter device fixed address.

The dynamic ID address of the device is determined by the home gateway, and its length can be determined by the actual application scenario. For example, in one embodiment, the dynamic id address is composed of 2 bytes, then a total of 65536 device dynamic id addresses can be represented from 0x00 to Oxfflff. Since the dynamic id address is only two bytes, it is very short, in the same wise association. ^ The address in the home network is also sufficient, so using this address as the communication address of each device on the bus can reduce the communication time, reduce the probability of data conflict, and greatly improve the communication efficiency. Of course, other lengths, such as one or more bytes, may be used to force the ID.

Figure 4 shows the electrical connector circuit structure used in the present application. The key to the infrared socket is two points. One is that the signal line is in line with the power line to facilitate wiring; the other is to connect the signal lines in a red way at the power socket. In other embodiments, other wireless communication methods, such as Bluetooth, 2.4G, etc., may also be employed.

Figure 5 shows the electrical connector module structure used in the present application. The signal line of the infrared socket adopts the 485 bus, which has the advantages of long transmission distance and strong anti-interference ability. All signal lines are routed along with the power supply, avoiding the problem of re-wiring. In the socket, for the signal line can be well combined, the infrared transmission method is adopted, that is, the SA-infrared transceiver 3⁄4S on the socket side and the 3⁄4S-infrared transceiver device on the plug side. With infrared transmission, the signal line adopts a non-contact connection, which is reliable and convenient, and avoids the problem that the smart electric appliance needs to rethink the signal line connection.

The infrared socket data exchange process is as follows:

1) Send a fixed address: When the infrared plug of the terminal appliance is connected to the infrared socket of the composite bus, the terminal appliance first sends a fixed address to the gateway, and the CPU 1 in FIG. 5 sends the fixed address to the socket CUP2 by the agreed infrared communication protocol. After receiving the infrared coded signal, the socket decodes, obtains a fixed address, and registers the fixed address, and simultaneously notifies the gateway through the fixed address notification message.

2), assign dynamic id address: When the gateway receives the fixed address and approves it, it will assign a dynamic id address to the socket corresponding to the appliance, and the appliance itself does not need to record the dynamic id address. The gateway should notify the corresponding socket of the assigned id address, and must send the received fixed address as the destination address of the communication to the destination address, and when the home appliance sends the fixed address to the gateway, the gateway is recorded. The fixed address of the home appliance, therefore, the gateway sends the dynamic id to the socket CPU2 through the address allocation message, and the CPU2 first matches the fixed address data. If the matching is successful, the dynamic id address is registered, so that the subsequent communication adopts the dynamic The id address is used as the source address and destination address of the communication. Due to There is no need for the device to directly store the assigned address, which reduces the requirements for implementing smart device control, and a wider range of common devices can be applied to the smart home network.
