The control mode is flexible and is not limited by geographic positions.
Step S303, when the wired connection with the fixed device is detected, the communication mode with the fixed device is switched to the wired communication mode for communication so as to control the controlled equipment.
When the establishment of the wired connection is detected, the communication mode is switched to a wired communication mode, such as USB interface communication, to control the controlled device. Because the wired communication mode has the advantage of stable control effect, when the wired connection is established, the wireless control is indicated to have a problem at the moment or the user does not consider factors such as control places, and the like, so that the most stable control mode is selected, and the optimal control effect is obtained.
According to the embodiment, whether the wired connection is established with the fixing device or not is detected, so that a more control mode is selected, and when the establishment of the wired connection is detected, the control mode is seamlessly switched into a wired communication mode, so that the optimal control effect is achieved.

As an alternative embodiment, the wired connection is a USB interface connection, and detecting whether the wired connection is established with the fixing device includes: and detecting whether the USB interface has input voltage or input current.
In this embodiment, whether the fixing device is connected to the central controller may be determined by detecting the input voltage and current. When detected, determining that the two are connected; otherwise, the two are not connected.
Since the charger may be connected to the central controller instead of the fixing device, in order to avoid erroneous judgment, in this embodiment, detecting whether a wired connection is established with the fixing device further includes: when detecting that the USB interface has input voltage or input current, judging whether equipment accessed by the USB interface is a fixed device or not; when the equipment accessed by the USB interface is a fixed device, the wired connection with the fixed device is established.
And judging whether the equipment accessed by the USB interface is a fixed device or not, namely, carrying out identity recognition on the equipment accessed to the central controller. The specific process is as follows:
and checking the power supply condition of the USB through a Linux kernel script, and when U (USB) is larger than 5v, considering that the USB interface is provided with access equipment (the access equipment is provided with a fixing device and a charger, and further carrying out identity recognition on the access equipment). The detection service program of the central controller obtains USB Device (including a fixing Device or a charger) connected with a USB Host through a getDeviceList () function of the USBManager, further verifies whether the getDeviceProtocol (), getVendorId (), getDeviceName () of the USB Device accords with the identity agreed by the two parties (defined according to the development scheme of each manufacturer), and if so, the verification is passed; otherwise, the flow does not pass. After the first detection and verification pass, the USB Host allocates an address addr to the USB Device; meanwhile, the central controller sends data or commands to the addr address through the USB interface so as to realize communication with the fixed device. When the notification is verified later, data transmission is directly performed through the address addr.
In this embodiment, the wireless communication mode is correspondingly provided with a first thread, the wired communication mode is correspondingly provided with a second thread, and when communication is not performed, both the first thread and the second thread are in a blocking state.
Threads typically have 5 states: a create state, a ready state, an operational state, a death state, and a blocking state.
In this embodiment, the corresponding threads may be set for the functional items in the central controller that control the controlled device, for example, a first thread for wireless communication and a second thread for wired communication. After the thread runs, the thread enters a blocking state through a sleep () method, and waits for a user to input a command so as to let the current CPU overhead be given to other threads. The thread in the blocked state has acquired other running resources besides the CPU, and when a certain thread running condition is satisfied, the thread can be awakened to enter the running state through other threads notify ().
Specifically, under the condition that a control command for controlling the controlled equipment is received, when the wired connection with the fixed device is not detected, the first thread is awakened, and the first thread and the fixed device communicate in a wireless communication mode; when the wired connection with the fixed device is detected, the second thread is awakened, and the communication mode with the fixed device is switched to the wired communication mode for communication.
When the central controller detects that the service program does not detect that the access fixing device exists, the detection service program is utilized to enable the USB interface communication thread (second thread) sleep to be in a blocking state, and then the communication thread (first thread) of the WiFi module is awakened through notify to immediately respond to the operation of a user, so that seamless switching is realized. Meanwhile, the fixing device is also connected with the router through the WiFi module, the router waits for receiving the control quantity sent by the central controller, and the central controller receives the state quantity of the fixing device.
When the central controller detects that the service program detects that the peripheral is arranged and the addr of the peripheral is a designated, namely a fixed device, the detection service program is utilized to enable the WiFi module communication thread (first thread) sleep to be in a blocking state, and then the USB communication thread (second thread) is awakened by the notify to immediately respond to the operation of a user, so that seamless switching is realized.
The controlling of the controlled device in this embodiment includes: establishing a message pipeline with the fixing device through wired connection or wireless connection; when a control command for controlling the controlled equipment is received, the control command is sent to the fixing device through the message pipeline, and the fixing device controls the controlled equipment connected with the fixing device by using the control command; and receiving the data of the controlled equipment returned by the fixed device through the message pipeline.
And a message pipeline is established between the central controller (USB host) and the fixing device (USB device), when the central controller is triggered by user behaviors, the central controller sends data to the fixing device through the message pipeline, the fixing device returns corresponding data of the unit to the central controller, and the central controller responds to the user behaviors.
Fig. 4 shows another alternative implementation of the method of this embodiment, taking the fixing device as a base, and the communication interface as a USB interface as an example for explanation. When in first use, a USB driver is preloaded in the fixed device, and when in first power-on, the fixed PID is allocated to the driver by writing the USB driver into a registry (10001). The central controller detects the program service detection voltage, and sends a reset request after waiting for 100 ms.
When not used for the first time, as shown in fig. 4, the method comprises:
in step S401, the central controller detects whether a USB device is connected. If so, step S402 is performed, otherwise detection continues.
In step S402, the central controller sends a frame of authentication command packet to the base.
Step S403, after receiving the instruction packet, the base returns the identity information according to a preset protocol.
In step S404, the central controller verifies the identity information returned by the base, and after the verification is passed, an address is allocated to the base.
In step S405, after the control is triggered by the user, a message pipe is established, and the data packet is sent to the address of the base.
In step S406, the base returns the state quantity of the controlled device to the central controller.
Step S407, detecting whether the central controller is disconnected from the base. If disconnected, the process returns to step S401, and otherwise continues detection.
