Description
Technical Field
The invention relates to a home network and remote controller technology, in particular to an interactive network remote control system and an intelligent wireless remote controller.
Background
The remote controller technology is a mature technology developed at present, is widely applied, and is particularly applied to household appliances, so that people can operate the appliances more easily and conveniently.
A conventional remote control system is generally unidirectional and simple, and its basic principle is shown in fig. 1, and fig. 1 is a schematic diagram of the basic principle of the prior art remote control system. As shown in fig. 1, the conventional remote control system includes a remote controller 101, a remote control receiving head 102 included in an electric appliance 100, a remote control code processing circuit 103, and an electric appliance main body 104. The traditional household appliance remote control system is characterized in that: data is unidirectional, the system structure is simple, and the function is single. The remote controller sends an electrical appliance control command to a remote control receiving head 102 included in the electrical appliance 100 through a wireless transmission medium such as infrared rays and sound waves, the receiving head 102 receives signals such as infrared rays and sound waves, and the remote control code processing circuit 103 converts the signals into specific electric signals to control the electrical appliance main body 104.
It can be seen that the traditional remote control system is characterized in that: one electric appliance is matched with one remote controller, data is unidirectional, the system structure is simple, and the function is single. Since the state of the remotely controlled appliance needs to be checked in the field after the remote controller in the prior art sends the remote control key code, otherwise, it is impossible to know whether other keys should be pressed again, which obviously brings trouble to the user operation. Moreover, with the increase of household appliances, the number of remote controllers is increased, which brings certain inconvenience to the operation of the appliances.
In view of the above situation, a "direct control type remote controller/system" is presented, which is a remote controller/system that directly sends control commands to controlled devices by a remote controller, and is implemented by adding a module for analyzing signals or returning status information to the remote controller and the controlled devices. This approach also fails to get rid of the orientation requirement of a conventional remote control for a remotely controlled device. It is not suitable to hope that the direct control type remote controller realizes advanced functions such as interaction, multifunction, remote control, etc.; in order to directly control various devices by a traditional remote controller and realize interaction between each device and the remote controller, a new protocol needs to be created, and in addition, the functions of controlling a plurality of devices and remote control need to be realized, the requirements will make the direct control type remote controller complicated and expensive, and the performance is difficult to guarantee and easy to damage.
With the popularization of computers and networks, new technical fields appear at present: intelligent home network technology. It is a comprehensive technology integrating computer network, electric appliance control and sensor technology.
The main body of the intelligent home network technology is a home network, and a network model thereof is shown in fig. 2, and fig. 2 is a schematic diagram of a structure of a home network in the prior art. As shown in fig. 2, the home network model is divided into a backbone network and a control network.
Firstly, a backbone network: the transmitted information is large in amount, mainly including common data, multimedia broadcast data, multimedia communication data, and the like, and can also transmit control information. Currently, the ethernet architecture is generally adopted, and a common 10/100BaseT network line is used. Which is connected to a computer 201, home printer 202, other home network devices 203, and to a control network through a control gateway 204.
II, controlling a network: the control information is mainly transmitted, and a small amount of data information can also be transmitted, and the control network and the backbone network realize communication by a control gateway. Currently, the system can be implemented by using a system architecture such as a consumer electronics bus (CEBus, also called a home bus). Which connects various electrical devices 205 and to the backbone network through a control gateway 204.
Third, the control gateway 204: while the special network port of the backbone network is connected with the backbone network, and the special network port of the control network is connected with the control network. Thus, the computer 201 on the backbone network can control the electrical devices 205 in the control network through the control gateway 204.
It is obvious that in the home network, the control and operation of various electric appliances are controlled by a computer connected to a backbone network at present, a series of processes such as starting up and entering an electric appliance operating system are required, and the use is not simple and convenient enough and random in the actual home.

In this case, there are three embodiments, and each of the embodiments will be described below.

The devices on the backbone network are all PC architectures, as shown in fig. 11, which include a hardware abstraction layer 125, an operating system 124, supporting software 123, and the like. In addition, the other application 122 may perform data transmission with the reception feedback program 121. The software receives feedback points in many control modes, generally, various network command messages are sent, for example, a remote controller can access a control gateway through a web page, the web page is a control page, a CGI command is sent by clicking each control button, and a CGI program on the control gateway executes an actual action when a CGI command is sent. The CGI program is now an executing application.
In this embodiment, the control network of the home network is implemented by a consumer electronics bus (CEBus, also called a home bus) architecture, and is connected to a plurality of electrical devices 310, where each electrical device 310 is installed with a receiving feedback circuit 311, which is a hardware receiving feedback point unit, and receives the remote control command sent by the control gateway 305, controls the remote controlled device 310, and sends the state of the remote controlled device 310 to the control gateway 305.
Fig. 10 is a schematic diagram of a receiving point feedback circuit 311 of a control network device in the interactive network remote control system according to the present invention. As shown in fig. 10, the receiving feedback point circuit includes: a CPU 111 and its necessary ROM 112 and RAM 113, a control network networking module 110, a device state storage 114, and a control execution module 116 installed in a remotely controlled device main body 115.

The control gateway 305 of the home network mainly performs the function of connecting the backbone network and the control network in this embodiment, and its structure is shown in fig. 8, fig. 8 is a schematic diagram of the internal structure of the control gateway of the interactive network remote control system of the present invention, which includes a backbone network networking module 801, a CPU802, a control network networking module 803, and a RAM804 and a Flash ROM805 for storing necessary data. The control gateway 305 periodically checks the status of each controlled device by reading the status storage unit of the reception feedback circuit 311 of each device and feeds back the status information to the remote controller 301 at the same periodic intervals, so that the remote controller 301 knows the relevant status of each device to be controlled. The backbone network networking module 801 is a general network card, which can be wired or wireless, and realizes connection between the control gateway 305 and the backbone network; the control network networking module 803 may be composed of a serial communication module or a USB communication module, which realizes that the control gateway 305 is connected to the control network; the dashed-line wireless direct connection module 806 is a wireless module required for direct communication with the remote controller, and in this embodiment, the remote controller realizes network access by accessing a backbone network access point, and the module is not required, so that the module is indicated by a dashed line.
In this embodiment, the control gateway 305 is an important component for implementing the present invention in any implementation manner, and not only connects the backbone network and the control network in the home network, but also implements a function of protocol conversion between the backbone network and the control network. Moreover, when the remote control terminal is in the backbone network and needs to control the equipment in the control network; or when the remote control terminal is in a state that the control network is to control the equipment in the backbone network; or the remote control terminal is directly connected with the control gateway, and the control gateway plays a role in explaining and forwarding the remote control information when controlling the backbone network and the equipment in the control network. In short, when the remote control terminal and the remote controlled device are not in the same area network, such as not in the backbone network and not in the control network, the situations inevitably exist, the control gateway interprets and forwards the remote control information sent by the remote control terminal to the receiving feedback unit in the remote controlled device through the home network, and interprets and forwards the state information of the remote controlled device sent by the receiving feedback unit to the remote control terminal. In addition, the present embodiment provides an interpretation module in the control gateway 305, which realizes the conversion between the remote control code of the remote control terminal and the information recognized by the remote control device.
