Abstract

The embodiment of the invention provides terminal equipment, input current control method and device thereof. The method comprises the steps of: initializing marking variable, wherein the marking variable is used for marking the controlled condition of the input current of the terminal equipment; obtaining the input current of the terminal equipment; judging whether the input current is more than the preset threshold; if the input current is more than the preset threshold, controlling the terminal equipment to reduce the data transmission rate or controlling the terminal equipment to reduce the transmission power of a radio frequency power amplifier; and carrying out first reset on the marking variable. Through the terminal equipment, the input current control method and device thereof provided by the embodiment of the invention, the working current of the terminal equipment can be ensured not to exceed the requirement on the special environment at any time, and the terminal equipment and a computer can be ensured to work safely without being damaged or burnt by the large current caused by high-speed and large-power work of the terminal equipment.

Description

technical field [0001] The present invention relates to terminal equipment, in particular to a terminal equipment input current control method, device and terminal equipment. Background technique [0002] With the rapid development of technology, the standard of terminal equipment is getting better and better, and the data transmission speed is getting faster and faster, such as: HSPA+ (Evolved High-Speed ​​Packet Access, Evolved High-Speed ​​Packet Access) standard data card data transmission Uplink can reach up to 11Mbps, downlink up to 42Mbps; DC-HSPA (Dual Carrier-HSPA, dual-carrier HSPA) uplink can reach up to 28Mbps, downlink up to 42Mbps; LTE (Long Term Evolution, long-term evolution) uplink can reach 50Mbps, the maximum downlink can reach 100Mbps. High transmission rate also means high power consumption. According to tests, the maximum power consumption of HSPA+ and LTE data cards far exceeds 2.5W at any time. However, the USB (Universal Serial BUS, Universal Seria...
