Specifically, the intelligent gateway undertakes the task of signal transfer, needs to provide access permission of various KNX media, and performs multiple interconversion of the KNX signal with other signal types. Specifically, a control module is arranged in the intelligent gateway and is a KNX control module. The KNX control module adopts a multifunctional interface designed by a TP-UART-IC chip to realize the access to different types of KNX media, namely different control protocol equipment supports to form a control network.

and the KNX input unit is connected with a KNX bus port on the intelligent gateway. The method comprises the following steps that firstly, signals from the outside are connected into a KNX control module through a KNX input unit, and the KNX input unit is connected with a protocol conversion unit;

and the protocol conversion unit is used for converting the accessed signals of the various KNX medium devices into KNX signals and/or converting the KNX signals into the signals of the various KNX medium devices. The protocol conversion unit is a core unit of the KNX control module and bears the burden of converting the signal of the external equipment into the KNX signal for subsequent processing. The design of the protocol conversion unit widens the equipment access type of the KNX intelligent gateway, and converts signals transmitted by some non-KNX protocol equipment into general KNX signals to carry out overall control on the intelligent home.

And the analog-digital conversion unit is used for converting the KNX signal into a digital signal and/or converting the digital signal into the KNX signal. Because the intelligent gateway bears the task of connecting the controller of the electric appliance and the server, signals from the intelligent gateway and the server need to be mutually converted, specifically, a KNX signal and a network signal are converted. Therefore, an analog-digital conversion unit is arranged in the KNX control module, the KNX signal formed by previous processing is converted into a digital signal, and the subsequent conversion into a network signal is facilitated.

The signal from the KNX medium device is input into the intelligent gateway through a KNX bus port of the intelligent gateway, is transmitted to the protocol conversion unit through the KNX input unit, is converted into a KNX signal in the protocol conversion unit, is transmitted to the analog-digital conversion unit, and is finally converted into a digital signal through the analog-digital conversion unit.

The KNX control module is arranged in the intelligent gateway in an embedded mode and is of a chip structure with a peripheral circuit. This intelligent gateway is used as the control transfer station and the signal processor of intelligent house, need insert control electrical apparatus through the KNX bus port that is equipped with on it, specifically, here KNX control module's KNX input unit links to each other with KNX bus port, and when multiple type external equipment (through different communication protocol transmission signals) inserts intelligent gateway, protocol conversion unit changes the communication protocol transmission signal of various differences, changes into the KNX signal that is suitable for this intelligent home systems. Specifically, the KNX control module further converts the KNX signal to generate a digital signal. The intelligent gateway is also internally provided with a central processing module, the KNX control module is connected with the central processing module, and the central processing module receives the digital signals for further conversion so as to facilitate the communication between the intelligent gateway and the background server.

The KNX control module structurally comprises a chip and a peripheral circuit, wherein the peripheral circuit is provided with a signal isolation circuit and a serial port digital quantity output circuit. The signal isolation circuit has a signal isolation function and processes the processed digital signals, so that the signal processing effect is better. Furthermore, the serial digital output circuit is mainly used for outputting digital signals.

Based on the function of a KNX control module in an intelligent gateway, a signal processing method is designed, and the signal processing method comprises the following steps:

s51, converting the signal transmitted into the intelligent gateway by the external equipment into a KNX signal;

s52, converting the KNX signal into a digital signal;

and S53, transmitting the digital signal to the central processing module, and converting the digital signal and the network signal.

The method is used for describing the conversion of signals from a KNX bus port to a server, and mainly relates to a signal processing method related to the transmission process of feedback signals of an electric appliance from an electric appliance control end and the initialization of household electric appliances of an intelligent home.

Furthermore, the signal processing method also has a reverse processing method, which describes the signal transmission process of sending the electric appliance control instruction to the electric appliance control end by the server and receiving the electric appliance control instruction. The reverse processing method and the processing method are both realized based on a chip in the intelligent gateway, and the set data of the chip is updated in real time or at regular time. Specifically, the chip inside the intelligent gateway comprises a KNX control module and a central processing module. Due to the fact that in the using process of household appliances, along with the improvement of equipment updating and control methods, programs and algorithms on which the signal processing method is based are changed, and therefore signal processing is more complete and powerful.

The reverse signal processing method specifically comprises the following steps:

s51', converting the network signal from outside into digital signal through the central processing module;

s52', converting the digital signal into a KNX signal;

and S53', converting the KNX signal and transmitting the KNX signal to the corresponding external equipment through the intelligent gateway KNX bus port.

Further, the external network signal is accessed to the intelligent gateway in a wired and/or wireless mode. Still further, the KNX bus port is connected with the external equipment in a wired and/or wireless mode.

Because the protocol signals of the external equipment accessing the intelligent gateway are various, different equipment (namely household electrical appliances) is involved. The signal processing method classifies the accessed external equipment or classifies protocol signals of the external equipment, and converts the protocol signals into KNX signals in batches according to types. Specifically, for example, the access signals of the lighting devices are simultaneously converted, or the signals of the twisted pair equipment supporting the TPUART protocol are simultaneously converted. Here, it is also possible to set priorities to various types of devices or protocols, perform conversion in accordance with the priority order, and preferentially perform conversion processing on signals that are in high priority and are to be processed urgently. The advantages of such a design are: the conversion is more efficient, and the working efficiency of the intelligent gateway is improved.

Further, the setting of the priority here is based on the type or attribute of the external device. Such as: the conversion of certain protocol signals to KNX signals takes longer and is delayed or processed during the low peak period of the appliance. Such as: some equipment, such as refrigerators, access controls and the like, need to feed back the working state of the equipment all the time, and the equipment is preferably processed before use.

Further, since the intelligent gateway is also in communication with the mobile terminal, parameters of related communication and control parts are remotely modified, which also affects the connection method and communication content of the intelligent gateway and the mobile terminal.

The intelligent gateway is also internally provided with a communication module which receives a parameter adjusting file sent by the server, and specifically, the communication module establishes communication connection with the server through automatic and/or manual triggering; the intelligent gateway is also provided with a controller, the controller is connected with the communication module, and the controller processes and distributes the parameter adjusting files received by the communication module. Specifically, the controller distributes and transmits the modified files in the parameter adjusting files to the corresponding modules to be modified, and the modules to be modified receive the modified files corresponding to the modules to be modified to modify the parameters.

Specifically, a control method is provided for an intelligent gateway capable of remotely adjusting parameters. The control method is based on the remote server to modify the parameters of the intelligent gateway, wherein the parameters are in a broad concept and comprise firmware update of the intelligent gateway, programs written on a chip, parameters of an interface and other circuit parts, and the internal circuit parts can be modified through software.

The method specifically comprises the following steps:

s61, accessing the intelligent gateway to an intelligent home for initialization configuration; the initialization configuration comprises automatic burning of the latest version of the intelligent gateway and address allocation of the intelligent household electrical appliance control end. And the method can also comprise interface parameter setting of the intelligent gateway and the like.

S62, the intelligent gateway sends a version inquiry signal to the server at regular time, and the server compares the current version with the latest version of the intelligent gateway; because the intelligent gateway can involve huge electric appliance control when in use, if the intelligent gateway is upgraded in the active period of the use of the electric appliance by a user, the use of the intelligent home can be influenced. The method is designed to update the intelligent gateway regularly, generally once a week, at the early morning time when the user is inactive, and a prompt is sent to the user before automatic updating to remind the user to reduce the control and use of the electric appliance as much as possible in the upgrading time period of the intelligent gateway.

S63, the server judges that the current intelligent gateway version needs to be updated, and feeds back an update signal to the intelligent gateway;

and S64, the intelligent gateway receives the feedback updating signal, establishes a channel with the server and receives the updating file from the server to perform automatic burning updating.

When updating, the intelligent gateway firstly sends a version inquiry signal to the server to inquire whether the version currently used by the intelligent gateway is the latest version. The server receives the inquiry signal from the intelligent gateway to perform judgment and feedback. And after judgment, if the version of the current intelligent gateway needs to be updated, feeding back an update signal to the intelligent gateway. And after receiving the fed-back updating signal, the intelligent gateway establishes a channel with the server to receive the updating file from the server for automatic burning updating. If the used version is the latest version after judgment, the server sends a feedback comparison result to the intelligent gateway and tells the intelligent gateway that the updating is not needed.

After the automatic burning upgrade of the step S64 is completed, the intelligent gateway automatically performs a restart. And after the restart, the latest version party is put into use.

And the intelligent gateway also receives a modification file which is issued at any time by the established connection server so as to repair the internal Bug of the intelligent gateway or modify the basic parameters. In the using process of the intelligent gateway, the possibility of incompatibility of the access equipment or error of control data can occur, on one hand, the problem can be solved by improving the electrical equipment, and on the other hand, the parameters in the intelligent gateway also need to be adjusted in real time so as to adapt to the continuously changing actual situation.

When the connection between the intelligent gateway and the server is established, the server can immediately send an instruction or a file to adjust and modify parameters in the intelligent gateway, and can also carry out remote bug repair after receiving bug information in the intelligent gateway.

Specifically, the basic parameters include 485 protocol parameters and/or security equipment type parameters and/or version update and/or database expansion of a chip in the intelligent gateway. After the 485 protocol parameter and the security trunk node parameter are modified by the control method, the types of the accessed third-party equipment and the security equipment can be expanded.

After the version of the chip is updated, a signal processing algorithm inside the intelligent gateway can be modified, such as conversion between an internal KNX signal and a network signal, or conversion between a signal transmitted by other protocol devices and a KNX signal. After modification, the information processing capacity of the intelligent gateway can be enhanced, and the working efficiency of the intelligent gateway is greatly improved.

In step S64, if the automatic recording upgrade is suspended and/or interrupted, the intelligent gateway records the suspension and waits for the next version inquiry signal to be sent for the automatic recording upgrade. In the automatic burning and upgrading process of the intelligent gateway, some unexpected situations can occur, such as sudden power failure, network disconnection or user misoperation. If the situation influences the automatic burning upgrade, the intelligent gateway records the automatic burning upgrade. And when waiting for the timing update of the next period, the intelligent gateway continues updating.

Preferably, if the time for two updates is too long, the intelligent gateway starts timing from the failure of the last burning update, and the next update time is not reached after a certain time. The intelligent gateway is controlled to send out a user prompt, the user manually or the intelligent gateway automatically updates in the early morning, and the updating step is unchanged.

In addition, the server can also automatically push version updating information to the intelligent gateway or the user side, and the user can manually select or the intelligent gateway automatically select to establish a channel with the server for burning and upgrading. Preferably, the control method can also manually or automatically pause and start the burning upgrading process in the burning upgrading process of the intelligent gateway.

Further preferably, after the user receives the parameter modification and bug repair signals from the server, the user can manually select to suspend or reject the parameter modification. Because some users may use some household appliances under special conditions, the parameter modification operation of the intelligent gateway is not suitable to be performed during the use period, and the operation of the intelligent gateway can be autonomously selected at the moment.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
