Problems solved by technology
This solution has many disadvantages. On the one hand, when the GPRS of the IoT module is offline, the IoT module only needs a small standby current, and the linear voltage conversion device or DC / DC switching power conversion device operates at a lower Under load current, its efficiency is usually low; on the other hand, when GPRS is online or data transmission requires a large current, this requires a linear voltage conversion device or a DC / DC switching power converter to have a large output current, both Increases the cost of the module and is not conducive to the miniaturization of the module

An embodiment of the invention provides an intermittently powered Internet of Things (IOT) module device and an IOT system. The device includes a conversion circuit, an energy storage component, a charging control circuit, and a main control chip. The conversion circuit is electrically connected with both the energy storage component and the charging control circuit. The main control chip is electrically connected with both the energy storage component and the charging control circuit. The main control chip outputs a first control signal to the charging control circuit to control the conversion circuit to work in a first predetermined time so that the conversion circuit can charge the energy storage component. The main control chip outputs a second control signal to the charging control circuit to control the conversion circuit to stop working in a second predetermined time, wherein the first predetermined time and the second predetermined time form an intermittent power supply cycle. Through the main control chip and the energy storage component, the intermittent powering of the energy storage element by a power supply can be realized, the power consumption is reduced, the service life of the power supply is prolonged, the intensity of module maintenance is reduced, and the practicability is high.
Description
technical field [0001] The invention relates to the field of the Internet of Things, in particular to an intermittent power supply Internet of Things module device and an Internet of Things system. Background technique [0002] At present, in the existing technology, the traditional IoT module power supply circuit uses a linear voltage conversion device or a DC / DC switching power conversion device to convert a higher battery voltage into a lower power supply voltage for the module's single-chip microcomputer and GPRS module. This solution has many disadvantages. On the one hand, when the GPRS of the IoT module is offline, the IoT module only needs a small standby current, and the linear voltage conversion device or DC / DC switching power conversion device operates at a lower Under load current, its efficiency is usually low; on the other hand, when GPRS is online or data transmission requires a large current, this requires a linear voltage conversion device or a DC / DC switchi...
