Heating system used for electronic device

Abstract

The invention discloses a heating system used for an electronic device. The heating system is used for increasing environment temperature inside the electronic device and comprises a sensing module, a comparing module, an operating module and a heating module, the sensing module is used for sensing the environment temperature to generate an environment temperature value, the comparing module is coupled to the sensing module and used for generating a first control signal and a second control signal according to the environment temperature value, the operating module is coupled to the comparing module and used for converting power source voltage to output heating voltage and adjusting the output heating voltage according to the second control signal, and the heating module is coupled to the comparing module and the operating module and used for deciding whether the heating voltage is used for heating or not to increase the environment temperature. By the heating system, the electronic device can flexibly execute heating to increase the environment temperature inside the electronic device without exceeding required power consumption.

Description

technical field [0001] The present invention relates to a heating system for an electronic device, in particular to a heating system that can flexibly perform heating to increase the internal ambient temperature of the electronic device without exceeding a specific power consumption. Background technique [0002] Generally speaking, electronic devices that transmit data signals through the Ethernet network, such as access points, IP phones, or IP cameras, etc., need to be connected to a power cable to obtain the required power for normal operation. Therefore, in order to solve the extremely inconvenient problems that electronic devices need to be connected to external power lines and add corresponding external power converters, on the basis of the original Ethernet transmission standard IEEE 802.3, it is also added that the power can be transmitted on the Ethernet line. Related standards, namely IEEE 802.3af or IEEE 802.3at standards, to implement Power Over Ethernet (POE) t...
