As shown in fig. 2A, another low-power consumption control method suitable for an internet of things control chip provided by the embodiment of the invention specifically includes the following steps:

and S210, if the receiving channel of the Internet of things control chip is monitored to not receive the data task within the designated time a1, transmitting a task query signal to the power distribution terminal.

Specifically, by monitoring whether the receiving channel of the internet of things control chip receives the data task within the designated time a1, it can be further determined whether the task query signal needs to be transmitted to the power distribution terminal. That is, if the data task is received by the receiving channel of the internet of things control chip within the designated time a1, a task inquiry signal may be transmitted to the power distribution terminal. If no relevant data task is received, no task inquiry signal needs to be transmitted to the power distribution terminal.

According to the receiving condition of the receiving channel of the Internet of things control chip on the data task in the appointed time a1, whether the task query signal is required to be transmitted by the matched electric terminal can be further determined, and the state of the Internet of things control chip can be conveniently determined by monitoring the data receiving and transmitting state.

The low-power consumption control mode is set based on the pre-negotiated suspension rule, and the mode control information is obtained, so that the control effects of energy conservation and electricity saving are realized, and further, the subsequent flow can be executed according to the obtained mode control information.

S250, a control signal carrying the mode control information is issued to the Internet of things control chip so as to trigger the Internet of things control chip to enter a low power consumption state according to a control mode specified by the mode control information.

Specifically, according to the acquired mode control information, a control signal including the mode control information is issued to the internet of things control chip, and then the control signal is executed according to a specified control mode in the corresponding mode control information by triggering the internet of things control chip, and the control signal enters a low-power consumption state.

The control signal carrying the mode control information is issued to the Internet of things control chip to trigger the Internet of things control chip to enter a low-power consumption state according to the control mode specified by the mode control information so as to realize the control effect of reducing energy and electricity, and further execute the subsequent flow after the physical control chip is controlled to enter the low-power consumption state.

The embodiment of the invention does not limit the polling monitoring mechanism adopted when the polling monitoring is executed. It can be understood that, in order to avoid the misoperation, the power-on signal can be forwarded to the switch power supply if the power-on signal issued by the power distribution terminal is continuously received within a predetermined period of time. The embodiment of the invention does not limit the effective avoidance mode adopted for avoiding misoperation. Therefore, the operation risk brought by misoperation of the terminal is reduced, and the purpose of reducing the power consumption is achieved.
