Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] combined reference Figure 1 to Figure 5 , The embodiment of the present invention provides a mobile phone group control circuit board, which is applied to a mobile phone group power supply and heat dissipation control system, and the circuit board includes a central control board, a USB_HUB board and a PCI-E power supply board.

[0024] figure 1 It shows the working diagram of the central control board circuit. The central control board converts the standard ATX computer power supply into 12V-12-channel output channel and connects it to the lower-level USB_HUB board; the control rack of the central control board supports 10 channels of cooling fans The 12V4PIN fan power output controls the action of the 12-way USB_HUB board and obtains real-time parameters through a shared RS232 single-master and multi-slave communication channel. ...

Abstract

The invention discloses a mobile phone group control circuit board, which relates to the technical field of Raspberry Pi, and comprises a central control board, a USB _ HUB board and a PCI-E power supply board, standard ATX computer power supply is converted into a 12V-12 channel USB _ HUB board with an output channel connected at the lower level; a control rack total cooling fan group of the central control board supports 10 paths of 12V 4PIN fan power supply output, and the action of the 12 paths of USB _ HUB boards is controlled and real-time parameters are obtained through a shared RS232 single-master multi-slave communication channel. The USB _ HUB board is used for converting the 12V power supply input switching power supply of the central control board into a 5V 6A power supply; the PCI-E power supply board converts a 12V output and RS232 communication channel provided by the central control board into a four-channel PCI-E slot type connection. The system is easy to expand, maintain, be compatible, connect, develop and control.

Description

technical field [0001] The invention relates to the technical field of raspberry pie, in particular to a mobile phone group control circuit board. Background technique [0002] The Raspberry Pi was developed by the "Raspberry Pi Foundation", a charitable organization registered in the United Kingdom, with Er Upton as the project leader. In March 2012, Eben Upton of Cambridge University officially launched the world's smallest desktop computer, also known as card computer, which is only the size of a credit card but has all the basic functions of a computer. This is the Raspberry Pi computer board, Chinese Translated as "Raspberry Pi". [0003] In response to the emergence of the Raspberry Pi, more equipment and related accessories have been extended, but due to the structure and size of the Raspberry Pi, the scalability of the Raspberry Pi is poor, difficult to maintain, difficult to be compatible, difficult to connect, difficult to Development, difficult to control.
