FIG. 1 is a conceptual diagram of the Z-Wave gateway of the present invention wirelessly connected to a plurality of sensors around.

Figure 2 is a block diagram showing the internal components of the Z-Wave gateway of the present invention.

In general, the Z-wave gateway can intelligently connect a variety of electrical equipment, such as monitors, lights, air conditioners, curtains, door locks, security monitoring, etc., and the Z-wave gateway can also be connected to a personal computer. A smart device such as a smart phone or a remote control to receive commands from the user from the smart device.

Please refer to FIG. 1. FIG. 1 is a conceptual diagram of the Z-Wave gateway of the present invention being wirelessly connected to a plurality of sensors around. First of all, we need to explain the induction in this case. 2 is a circuit that can be connected to the Z-Wave gateway 1 by Z-wave communication protocol, so it is like Z-Wave wireless products (such as monitors, lights, air conditioners, curtains, door locks, security monitoring). Etc., or a transmission and reception circuit that supports the Z-wave wireless two-way communication protocol, is included in the scope of inclusion.

The Z-Wave gateway device 1 includes a network communication module 16, and the network communication module 16 has a networking function, in addition to being directly connected to the home network, so that the user can understand the electrical equipment in the home anytime and anywhere. In the current state, even the Z-Wave gateway 1 is connected to the network service provider's host through the network communication module 16 and establishes a network connection with a cloud platform 4. Combined with cloud services, users can control home appliances from the external environment, learn about the status of each electrical device, and receive notifications.

FIG. 2 is a block diagram showing the internal components of the Z-Wave gateway of the present invention, and please refer to FIG. 1 and FIG. 2 together. The Z-Wave gateway 1 includes a Z-Wave wireless communication module 11, a memory 12, an arbitration circuit module 13, and a central processing unit 14. The Z-Wave wireless communication module 11 establishes a signal connection with the external complex sensor 2 in accordance with the Z-wave communication protocol. Similarly, each sensor 2 must be individually and individually included in the network of the Z-Wave gateway 1 before use. After the addition, the Z-Wave wireless communication module 11 will generate a status data correspondingly, and at least one new specific model sensor 2 is added to the record of the Z-Wave wireless communication module 11 in the status data. And subsequent status data will be continuously updated. The status data is then transferred to the memory 12 for storage.

Specifically, the status information includes the Z-Wave wireless communication module 11 data, a sensor status data, and a sensor setting data. At least one. For example, the Z-Wave wireless communication module 11 data refers to the information that is included with a particular luminaire, and the sensor status data refers to the current on and off state of the specific luminaire. The sensor setting data refers to the setting information of the scheduled opening and closing time schedules of the specific lamp. However, the above is only one of the convenience descriptions, not a limitation.

In the present case, the memory 12 is preferably a non-volatile memory (Non-Volatile Memory). The advantage of the non-volatile memory is that the state stored in the non-volatile memory is in the case of no continuous power supply. The information will not disappear.

The arbitration circuit module 13 of the present invention will be described. The arbitration circuit module 13 is arranged to establish a special circuit loop for capturing state data stored in the memory 12. The detailed implementation is that the Z-wave wireless communication module 11 and the memory 12 are connected by a four-wire serial peripheral interface (SPI) for making a Z-wave wireless communication module. 11 can communicate with the memory 12 in point-to-point communication. The arbitration circuit module 13 includes a control circuit and four capture lines, the control circuit is connected to the Z-Wave wireless communication module 11, and the four captured circuit circuits are connected to the four-wire serial bus interface. Four wires in the middle. With this circuit arrangement, when the central processing unit 14 controls the arbitration circuit module 13 and wants to retrieve state data from the memory 12, the circuit between the Z-Wave wireless communication module 11 and the memory 12 temporarily stops operating. Therefore, the arbitration circuit module 13 extracts the status data in the memory 12 and transfers it to the storage medium 3 for backup storage.

This case proposes two ways of backup storage. One is Z-Wave The gateway 1 has a Universal Serial Bus (USB) interface 15, and the central processor 14 transmits the status data to the storage medium 3 through the use of the universal serial bus interface 15, wherein the storage medium 3 can be a USB flash drive, and status data is backed up on a USB flash drive. Therefore, when the Z-wave gateway 1 is damaged, it is only necessary to take out a new Z-wave gateway (also including the original Z-wave gateway that has been repaired), and then the status data in the USB flash drive. Reverting to a memory in the new Z-wave gateway, the new Z-wave gateway can be reconnected to the sensor 2 already added to the original damaged Z-wave gateway. In this way, the sensor 2 can be connected to the new Z-wave gateway without returning to the factory default value, and the new Z-wave gateway can be re-added separately to all the sensors 2 around it. , saves a lot of operation time to re-add.

The second is that the Z-Wave gateway 1 is connected to a computer, and the Z-Wave gateway 1 has a corresponding signal line interface 15' for transferring data and presenting it to the computer 8 for the user to input commands for backup status. data. The user operates the user interface 80 (UI) of the computer 8 to cause the central processing unit 14 to control the arbitration circuit module 13 to transfer the status data to the storage medium 3'. The storage medium 3' can be a storage hard disk of the computer itself. And the status data is backed up on the storage hard drive. Therefore, when the Z-Wave gateway 1 is damaged, the user only needs to take out a new Z-wave gateway (also including the original Z-wave gateway that has been repaired) and connect the USB flash drive. The internal status data is restored to a memory in the new Z-wave gateway, and the new Z-wave gateway can be connected to the original damaged Z-Wave gateway 1 Restore the connection and save time for a large re-addition of the operation.

In summary, the Z-Wave gateway in this case is specially equipped with an arbitration circuit module, so that the state data stored in the memory is additionally transmitted to a storage medium for backup storage. In this way, when the Z-Wave gateway is damaged, as long as the status data stored in the storage medium is transferred to another Z-Wave gateway, the other Z-Wave gateways need not be re-associated with each one. The surrounding sensors are added separately, and can immediately inherit the state of the previous Z-Wave gateway and quickly connect each of the surrounding sensors.

The above embodiments are merely illustrative of the principles and effects of the present invention, as well as the technical features of the present invention, and are not intended to limit the scope of protection of the present invention. Any person skilled in the art can make changes or equal arrangements that can be easily accomplished without departing from the technical spirit and spirit of the present invention. Therefore, the scope of protection of the present invention should be as set forth in the scope of the patent application described later.
