Problems solved by technology

At present, the recommended methods for power supply of wireless communication modules by various manufacturers are as follows: figure 1 , the processor supplies power to the wireless communication module by controlling K1 and K2, and some of them are not controlled, and the power supply is directly connected to the module, which will lead to a waste of processor I / O resources or cannot be completely powered off when the module needs to be powered off. Remove the power supply, the module power-off reset is not complete, and data errors occur

Embodiment Construction

[0009] The present invention combines the power supply requirements of each manufacturer, whether it has its own 1.8V power supply and the required power-on sequence, adds a coordinated control mechanism control strategy, designs the control of power supply, and the corresponding power-on sequence, and proposes a joint control method. image 3 is the control block diagram of the joint control method.

[0010] refer to image 3 The joint control method proposed by the present invention mainly includes three parts: a 3.8V control circuit, an external 1.8V power supply, a built-in 1.8V power supply selection circuit, and a 1.8V power supply power on and off control circuit. The 3.8V control circuit is controlled by the processor to control K1 to determine the power on and off of the module. The default value does not provide 3.8V voltage to the module. The way of external 1.8V power supply and built-in 1.8V power supply selection circuit is to use the built-in 1.8V power supply...

Abstract

According to a wireless communication module power supply control method provided by the invention, a joint control circuit is adopted, a processor only needs to control the joint control circuit, a 3.8 V power supply and a 1.8 V power supply are powered on and off in the circuit, and whether a manufacturer module carries 1.8 V power supply output or not is identified so as to determine whether the 1.8 V power supply supplies power to the manufacturer module internally or externally. Reliable power-on and reliable power-off of the circuit are guaranteed, the power-on and power-off time sequence of the circuit is controlled, processed IO resources are saved, and the power-on stability and the power-off thoroughness are greatly improved.

Description

technical field [0001] The invention belongs to the field of wireless communication power supply, in particular to a control circuit and method for wireless communication module power supply. Background technique [0002] The current development of wireless communication is changing with each passing day. Untrusted communication technology is fully used in the fields of edge computing, AI, and big data. With the gradual commercialization of 5G technology, the reliability and stability of wireless communication are very important. At present, 4G technology is very mature. The power supply of 4G wireless communication modules on the market is 3.8V (3.3V~4.3V), while the power level of the data interaction line is 1.8V. Weak 1.8V power output, only need to provide a 3.8V power supply to the module at this time, and the built-in 1.8V power supply cannot supply power to other circuits. Some modules do not have 1.8V power output, so two power supplies must be provided at this tim...
