Description
Technical Field
The invention relates to the field of communication, in particular to a cloud terminal with multiple power supply modes and a cloud computing system.
Background
Cloud Computing (Cloud Computing) is an emerging business Computing model. It distributes the computing task on the resource pool formed by a large number of computers, so that various application systems can obtain computing power, storage space and various software services according to the requirements. The cloud terminal equipment is matched with the cloud computing overall solution. In a cloud computing mode, desktops, application software and data storage of users are managed in a centralized mode, and the users can access a network through cloud terminal equipment to obtain traditional PC equivalent services. Because the desktop and the data are in the cloud, the user can access the respective desktop on any cloud terminal device without being limited by places.
The service provided by cloud computing comprises three aspects: iaaS (infrastructure as a service), paaS (platform as a service), saaS (software as a service). The virtual machine technology is an important means for effectively managing and fully sharing physical resources, an abstraction layer can be introduced between software and hardware of a computer system, an independent operation environment is provided for upper application, and sharing and multiplexing of hardware resources are realized. As a key technology of cloud computing applications, particularly, platforms, i.e., services, and infrastructures, i.e., services, provided by cloud computing must be based on virtual machines.
Through virtualization technology, a computer can be used as services provided by a cloud computing system, and the services are virtual computers in nature. The cloud terminal is connected with the desktop of the virtual machine or the physical machine remotely through a specific remote desktop link protocol (such as rdp, xrdp, vnc and the like), so that a user can use the resources of the connected virtual machine or physical machine.
Currently, most of cloud terminal devices on the market use an external dc power adapter to supply power: in a conventional hardware design, a hardware system of a cloud terminal device is generally only considered to provide a stable voltage and current value for the hardware system, so that the hardware system can operate. Generally, an interface between a power adapter and cloud terminal equipment is a circular power interface with positive inside and negative outside or negative outside and positive inside, and the power adapter supplies power to the cloud terminal equipment through the power interface. Therefore, in most cases, the user can only use the power adapter attached to the cloud terminal device to supply power to the cloud terminal device.
However, the power environment of the user is variable, and in many cases, the user may further own another device (for example, a power adapter of a USB interface) that can provide power for the cloud terminal device, or under limited environmental conditions, only limited power supply means (for example, only PowerOver Ethernet (POE) power supply) can be provided for the cloud terminal device, or the user cannot obtain external power supply (for example, outdoors) under the current environmental conditions, and in these cases, because the cloud terminal lacks a flexible power selection processing mechanism, the user cannot use the cloud terminal device on hand.

Most cloud terminal equipment in the market is provided with a battery, and is a simple disposable button battery which can provide a weak power output function, generally an alkaline lithium manganese battery or an alkaline zinc manganese battery, wherein the battery can provide very small voltage and current, and generally only provides 1.5V or 3V voltage. The button cell generally stores user configuration information of a Basic Input Output System (BIOS for short) in a ROM or stores Time information in a Real-Time Clock (RTC for short) module to supply power, cannot provide power supply for the operation of the whole machine, cannot perform charging operation, and can only be manually replaced by a new cell after the electric quantity of the button cell is used up.
The electric energy storage module 26 used in the embodiment of the present invention is different from the button cell in that: 1) The electric quantity that can be exported is different: the electric quantity stored in the electric energy storage module 26 is enough to provide power energy for normal operation of all processing units of the whole machine, and the cloud terminal can also normally operate the system for a period of time only by means of the electric energy in the electric energy storage module 26 under the condition that no external power supply is available. Most cloud terminals in the market can provide very small electric quantity, and cannot provide enough power energy for normal operation of all processing units of the whole machine. The voltage and current values of the button battery can only supply power for the RTC module, and the independent and simple clock circuit can continuously time under the condition of power failure of the whole system. Or the power is only supplied to the BIOS circuit, so that the configuration information changed by a user can be stored after the power of the whole machine is cut off; 2) The electric energy storage module 26 can not only supply power to the outside, but also charge in a state that the electric energy is not saturated, and the module can be reused. The general button is a disposable alkaline lithium manganese battery or alkaline zinc manganese battery, and when the electric energy in the battery is output externally, the button cannot be recharged for use and must be replaced manually.
It should be noted that: the cloud processing module 21 in this embodiment may support a cloud terminal operating system, for example: windows, linux, chrome and the like, can also run cloud computing client software, and can execute cloud related operations such as accessing to a remote desktop of a user.
It is understood that the input module 23 in the present embodiment can be, but is not limited to, a keyboard. If the input module 23 is a keyboard, the cloud terminal may be connected to other devices with input functions, such as a mouse, in a wired manner (for example, a USB interface unit, a PS2 interface unit, etc.) or in a wireless manner (for example, a bluetooth interface unit, a WIFI interface unit, etc.).
It is understood that the input module 23 further includes other devices with input function, such as a mouse, for example, a touch pad in a keyboard.
It can be understood that, in order to further adapt to user requirements, the cloud terminal in this embodiment may further connect to other USB peripherals through one or more USB interfaces, for example: u disk, data card, etc.
It will be appreciated that the output module 24 may be any display output interface, such as: a DVI interface, a VGA interface, an HDMI interface, etc.
Optionally, the network access module 22 in this embodiment may be a WIFI interface, configured to connect to the internet in a wireless manner.
In summary, the cloud terminal according to the embodiment of the present invention has the functions of the cloud terminal according to the first embodiment, and is further provided with an internal electric energy storage module, and when an external power supply is connected to supply power, the electric energy capacity of the internal electric energy storage module can be intelligently identified, the electric energy storage module is charged when the electric energy capacity does not reach saturation, and the charging operation on the electric energy storage module is cut off when the electric energy capacity of the electric energy storage module reaches saturation.
