In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for supplying power to an LPWA device, where the method includes:
step 100, judging whether the LPWA equipment in the awakening state enters a dormant state from the awakening state;
and 101, stopping power supply of the battery after the LPWA equipment enters a dormant state from a wake-up state, and supplying power by using energy received by a radio frequency wireless transmission mode and provided by wireless power supply equipment.
In the embodiment of the invention, the LPWA equipment in the awakening state judges whether to enter the dormant state from the awakening state; and after the awakening state enters the dormant state, stopping the power supply of the battery, and supplying power by using the energy received by the radio frequency wireless transmission mode and provided by the wireless power supply equipment. In the prior art, the power required by the LPWA equipment is completely provided by the battery, and the power required by the LPWA equipment in the dormant state accounts for 60% -70% of the total power of the battery, but in the invention, the LPWA equipment is powered by the wireless radio frequency mode in the dormant state to maintain the operation of the equipment, and when the LPWA equipment is in the activated state, the power is supplied by the battery, so that the battery configured by the LPWA equipment only needs to maintain the power required by the activated state of the equipment, the power requirement of the battery configured by the LPWA equipment is reduced, and the volume of the battery is also reduced.
The wake-up state of the LPWA device is an operating state of the LPWA device, and mainly includes a transmission state of the LPWA device and a transmission state of the LPWA device. The transmitting state of the LPWA equipment is the working state of the LPWA equipment for uploading data information, the receiving state of the LPWA equipment is the working state of the LPWA equipment for receiving downlink data information, and the two states are data interaction with the base station.
The sleep state of the LPWA device is an inactive state of the LPWA device, and mainly includes an IDLE state of the LPWA device and a PSM (Power Saving Mode) state of the LPWA device.
As shown in fig. 2, the PLWA apparatus of the present invention mainly has four components: LPWA equipment system 200, power supply system selection switch 201, wireless chip 202, and battery 203.
LPWA equipment system 200: for determining whether the LPWA equipment needs to enter one operational state into another.
Power supply mode selection switch 201: the method is used for judging that the LPWA equipment needs to enter another operation state from one operation state in the LPWA equipment system, and selecting the power supply mode needed by the current operation state through closing the power supply mode selection switch.
The wireless chip 202: the power supply device is used for supplying power by the energy source provided by the wireless power supply device received by the radio frequency wireless transmission mode when the LPWA device is in the dormant state.
Battery 203: for supplying operating current to the LPWA device when it is in the wake-up state.
Generally, the LPWA device may determine whether to enter the sleep state from the awake state in the following two ways.
Firstly, determining that the data needs to be switched into the dormant state from the awakening state according to whether the threshold duration of data transmission set by the dormant timer is up.
Optionally, the LPWA device determines that the sleep state needs to be entered from the awake state after a set sleep timer expires.
In a specific implementation, the LPWA device makes a protocol with an associated base station in advance to determine a time taken for performing one data transmission. When the sleep timer set by the LPWA device according to the protocol expires, that is, the time for performing one-time data transmission is used up, the LPWA device determines that the LPWA device needs to enter the sleep state from the awake state.
Therefore, the time length of data uploading of the LPWA equipment is determined regularly, namely the power supply mode can be determined in time according to the running state of the LPWA equipment, and the loss of the battery power is saved.
For example: assuming that the LPWA device needs to report the temperature of the swimming pool every hour every day, and the reporting time is 1 minute, when the reporting time of the LPWA device reaches 1 minute, the LPWA device determines that the device needs to enter a sleep state from a wake state, and the LPWA device enters the sleep state and supplies power in a wireless power supply manner.
And secondly, determining that the user needs to enter the dormant state from the awakening state according to the time length of the data which is not received and transmitted and the set threshold time length.
Optionally, the LPWA device determines that the LPWA device needs to enter the sleep state from the awake state after a duration of data transceiving reaches a set duration.
In implementation, the LPWA device monitors the awake state to monitor a transmission condition of data transmission, and counts time after the data transmission is completed, and when a duration that the LPWA device does not receive and transmit data is greater than a threshold set by the LPWA device and a base station in advance, the LPWA device determines that the awake state needs to enter the sleep state.
Therefore, the LPWA equipment determines whether to enter the dormant state from the awakening state according to the specific data transmission condition of the LPWA equipment, so that the adopted power supply mode can be determined in time according to the running state of the LPWA equipment, the loss of the battery power is saved, and meanwhile, the judgment whether to enter the dormant state from the awakening state is determined according to the time length for not receiving and transmitting data and the comparison between the LPWA equipment and the preset threshold value of the base station in advance, so that the data transmission can be ensured to be completely finished even if a large amount of data needs to be transmitted.
For example: assuming that the LPWA device needs to report the temperature of the swimming pool every hour every day, the threshold set by the LPWA device and the base station is 1 minute in advance, at this time, the duration of non-data transmission and reception exceeds 1 minute, and the duration of non-data transmission and reception is greater than the threshold set by the LPWA device and the base station in advance by 1 minute, the LPWA device determines that the sleep state needs to be entered from the wake state, and the LPWA device enters the sleep state and supplies power in a wireless power supply manner.
As shown in fig. 3, a schematic flow chart of the LPWA device entering the sleep state from the wake state in the embodiment of the present invention is as follows.
Step 300, the LPWA equipment is in a wake-up state;
step 302, the LPWA device in the wake-up state determines whether to enter the sleep state from the wake-up state, if so, step 202 is executed, otherwise, step 203 is executed;
step 302, after the LPWA enters the sleep state from the awake state, stopping the power supply from the battery, and supplying power by using the energy provided by the wireless power supply device received through the radio frequency wireless transmission mode;
in step 303, the LPWA device remains powered by the battery.
After the LPWA device enters the sleep state from the awake state, the LPWA device further determines whether the LPWA device determines that the LPWA device enters the awake state from the sleep state.
Optionally, after the LPWA device enters the sleep state from the wake state, the LPWA device determines whether to enter the wake state from the sleep state; and after the wireless power supply equipment enters the awakening state from the dormant state, stopping supplying power by the energy provided by the wireless power supply equipment, and supplying power by using a battery.
In the embodiment of the invention, when the LPWA equipment is in the dormant state, whether the LPWA equipment enters the awakening state from the dormant state is judged, and after the LPWA equipment enters the awakening state from the dormant state, the power supply is stopped by the energy provided by the wireless power supply equipment, and the power is supplied by the battery, so that the power supply mode can be timely switched when the LPWA equipment is in the awakening state, and enough current is provided for the LPWA to work.
Generally, the LPWA device may determine whether to enter the sleep state from the awake state in the following two ways.
Firstly, the LPWA device determines that the LPWA device needs to enter an awakening state from a dormant state when receiving an external stimulus.
Optionally, the LPWA device determines that the wake-up state needs to be entered from the sleep state after receiving the trigger interrupt.
In the implementation process of the embodiment of the invention, the LPWA equipment receives the external stimulus and receives the triggering interruption, and the LPWA equipment determines that the LPWA equipment needs to enter the awakening state from the dormant state through the triggering interruption, so that the LPWA equipment can be effectively applied to a monitoring system, and the emergency can send out an alarm in time.
For example: assuming that the LPWA equipment is a fire alarm, when a fire disaster occurs, the fire alarm receives smoke stimulation, the current of an internal circuit of the fire alarm changes, the fire alarm detects the change of the current of the circuit, determines that the LPWA equipment needs to enter a wake-up state from a sleep state, then wakes up the fire alarm, and a fire alarm system controls a power supply mode selection switch to supply power by using a battery, and the fire alarm works normally to send out an alarm.
The triggering interruption is a signal in the form of current or voltage formed inside the LPWA device when the LPWA device is subjected to an external stimulus, and the LPWA device can determine that the LPWA device needs to enter a wake-up state from a sleep state by detecting the signal.
And secondly, the LPWA equipment determines that the LPWA equipment needs to enter the awakening state from the dormant state according to the set awakening timer.
Optionally, the LPWA device determines that the wake-up state needs to be entered from the sleep state after a set wake-up timer expires.
In specific implementation, the LPWA device determines whether to enter a wake-up state from a sleep state by determining whether a set wake-up timer expires; therefore, long-term continuous data monitoring can be excellently realized, and experimental research is facilitated.
For example, assuming that a plant cultivation experiment is currently performed, the LPWA device needs to measure temperature data every 10 minutes and report the temperature data, so that before the LPWA device performs the task, a wake-up timer needs to be set in advance, the LPWA device enters a wake-up state from a sleep state every 10 minutes, measures the temperature and uploads the data, and thus the LPWA device is very beneficial to realizing long-lasting data monitoring.
As shown in fig. 4, a flow chart of the LPWA device entering the awake state from the sleep state in the embodiment of the present invention is as follows.
Step 400, the LPWA device is in a dormant state;
step 401, the LPWA device in the wake-up state determines whether to enter the wake-up state from the sleep state; if yes, executing step 302, otherwise, executing step 303;
step 402, after the LPWA enters the wake-up state from the sleep state, stopping power supply by the energy provided by the wireless power supply device, and supplying power by a battery;
in step 403, the LPWA device maintains power supply with the power source provided by the wireless power supply device received through the radio frequency wireless transmission mode.
As shown in fig. 5, a flowchart of a method for supplying power by an LPWA device in an embodiment of the present invention is shown.
Step 500, the LPWA equipment is in a wake-up state;
step 502, the LPWA device in the wake-up state determines whether to enter the sleep state from the wake-up state, if so, step 502 is executed, otherwise, step 503 is executed;
step 502, after the LPWA enters the sleep state from the awake state, stopping the power supply from the battery, and supplying power by using the energy provided by the wireless power supply device received through the radio frequency wireless transmission mode;
step 503, the LPWA equipment keeps using the battery to supply power;
step 504, the LPWA device is in a dormant state;
step 505, the LPWA device in the wake-up state determines whether to enter the wake-up state from the sleep state; if yes, go to step 506, otherwise, go to step 507;
step 506, after the LPWA enters the wake-up state from the sleep state, stopping power supply by the energy provided by the wireless power supply device, and supplying power by a battery;
in step 507, the LPWA device maintains the power supply using the power supplied from the wireless power supply device received through the radio frequency wireless transmission.
Optionally, the LPWA device supplies power by using the energy provided by the wireless power supply device received in the radio frequency wireless transmission manner, and charges the battery by using the energy provided by the wireless power supply device.
