Step S52, loading BIOS by the main module;

a step S53 of determining whether the vendor code is satisfied, and if yes, executing a step S54, and if no, executing a step S55;

step S54, CPIO outputs low level;

wherein, in the case where the vendor code Vender ID is 00, it is determined that the CPIO outputs a low level.

Step S55, GPIO outputs high level;

wherein, in the case where the vendor code vendor ID is 01, it is determined that the CPIO output is low.

Step S56, under the condition that the CPIO outputs low level, the service is switched to intelligent analysis and storage service;

step S57, under the condition that GPIO outputs high level, the service is switched into visual management platform service;

step S58 ends.

The memory 802 may be used to store software programs and modules, such as program instructions/modules corresponding to the signal switching method and apparatus in the embodiments of the present invention, and the processor 804 executes various functional applications and data processing by running the software programs and modules stored in the memory 802, that is, implements the signal switching method. The memory 802 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 802 can further include memory located remotely from the processor 804, which can be connected to the terminal over a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof. The memory 802 may be used for information such as a first level signal, a second level signal, and the like. As an example, as shown in fig. 8, the memory 802 may include, but is not limited to, the first acquiring unit 61 and the first switching unit 63 in the signal switching device. In addition, the present invention may further include, but is not limited to, other module units in the signal switching device, which are not described in detail in this example.

Optionally, the transmitting device 806 is configured to receive or transmit data via a network. Examples of the network may include a wired network and a wireless network. In one example, the transmission device 806 includes a Network adapter (NIC) that can be connected to a router via a Network cable and other Network devices to communicate with the internet or a local area Network. In one example, the transmission device 806 is a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.

In addition, the electronic device further includes: a display 808, configured to display the first service; and a connection bus 810 for connecting the respective module parts in the above-described electronic apparatus.

In other embodiments, the terminal device or the server may be a node in a distributed system, where the distributed system may be a blockchain system, and the blockchain system may be a distributed system formed by connecting a plurality of nodes through a network communication. Nodes can form a Peer-To-Peer (P2P, Peer To Peer) network, and any type of computing device, such as a server, a terminal, and other electronic devices, can become a node in the blockchain system by joining the Peer-To-Peer network.

According to an aspect of the application, a computer program product or computer program is provided, comprising computer instructions, the computer instructions being stored in a computer readable storage medium. The processor of the computer device reads the computer instructions from the computer-readable storage medium, and the processor executes the computer instructions to cause the computer device to execute the signal switching method provided in the signal switching aspect or the various alternative implementations of the signal switching aspect. Wherein the computer program is arranged to perform the steps of any of the above method embodiments when executed.

Alternatively, in the present embodiment, the above-mentioned computer-readable storage medium may be configured to store a computer program for executing the steps of:

s1, after the target device is powered on, obtain a first level signal of a first main control module of the target device, where the first main control module is used to manage the first service.

And S2, switching the first signal to the first main control module under the condition that the first level signal indicates a low level signal.

Alternatively, in this embodiment, a person skilled in the art may understand that all or part of the steps in the methods of the foregoing embodiments may be implemented by a program instructing hardware associated with the terminal device, where the program may be stored in a computer-readable storage medium, and the storage medium may include: flash disks, Read-Only memories (ROMs), Random Access Memories (RAMs), magnetic or optical disks, and the like.

The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.

The integrated unit in the above embodiments, if implemented in the form of a software functional unit and sold or used as a separate product, may be stored in the above computer-readable storage medium. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes several instructions for causing one or more computer devices (which may be personal computers, servers, network devices, etc.) to execute all or part of the steps of the method according to the embodiments of the present invention.
