Detailed ways

After 2020, mobile communication technologies and industries will enter the fifth generation of communications, which will expand economic life from the mobile Internet to the Internet of Things. With the rapid development of LPWA products, consumers are beginning to get tired of messy cables and batteries that need to be recharged. How to reduce the power consumption of LPWA products or extend the life of products has become a problem to be solved.

Various near-field and far-field charging wireless technologies on the market, including inductive, resonant, ultrasonic, and infrared charging, etc., all of which need to follow different standards. The current magnetic induction charging distance needs to be close. Charging can not meet the application needs of IoT products. With the continuous development of wireless radio frequency charging technology, the short-range and medium-range wireless charging technologies have gradually matured, and the current coverage can reach 100 square meters, and the charging efficiency is also greatly improved.

Among them, the wireless radio frequency charging technology uses the rectifying antenna to collect the electromagnetic wave energy in the environment and then converts the collected electromagnetic wave into electric energy through the conversion circuit. In the realization process, the electromagnetic energy collecting system can be directly used as the power source of the batteryless system, or As an auxiliary power source, it charges the battery or the auxiliary power of the battery. In the embodiment of the invention, both of the roles of the electromagnetic energy harvesting system are involved.

The characteristics of IoT products are that the standby time must be long, but the working time is relatively short. At present, the power supply of IoT products is mainly provided by the battery of its own configuration. Since the IoT products usually have a long standby time and a short working time, 60%-70% of the configured battery capacity is consumed in the standby process, and Product service time is usually more than 8 years. Based on the above characteristics, in order to ensure that the product can meet the needs of service time, it is usually to increase the battery capacity to solve this problem. This brings about an increase in the volume of the product, resulting in many scenes that require miniaturization and high appearance requirements cannot be used. Therefore, the LPWA device has a problem that the power supply battery is excessively large.

Combining the characteristics of both IoT products and wireless charging technology, we deploy wireless transmitters in specific areas and power the IoT products in the region, which corresponds to our IoT products designed to be in standby and hibernation. In the case of wireless power supply, switching to the built-in battery while working is still powered by the battery, because the IoT product working time is relatively short, which can greatly reduce the battery capacity and reduce the size of the product.

The present disclosure will be further described in detail with reference to the accompanying drawings, in which FIG. . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

As shown in FIG. 1 , an embodiment of the present disclosure provides a method for powering an LPWA device, where the method includes:

Step 100: The LPWA device in the awake state determines whether to enter the sleep state by the awake state;

Step 101: In response to entering the sleep state by the awake state, the LPWA device stops supplying power through the battery equipped by itself, and supplies power with the energy provided by the wireless power supply device received by the radio frequency wireless transmission mode.

In the embodiment of the present disclosure, the LPWA device in which the LPWA device is in the awake state determines whether the awake state enters the sleep state; after entering the sleep state from the awake state, stops the power supply through the battery equipped by itself, and uses the wireless received by the radio frequency wireless transmission mode. The energy provided by the power supply equipment is used to supply power. Compared with the LPWA device, the required power is all provided by the battery, and the LPWA device requires 60%-70% of the total battery power in the sleep state, and the present disclosure is powered by the radio frequency mode when the LPWA device is in the sleep state. Keep the device running. When the LPWA device is in the awake state, it is powered by the battery. Therefore, the battery configured by the LPWA device only needs to maintain the power required for the device to wake up, so that the battery capacity of the battery configured by the LPWA device is reduced, and the battery capacity is also reduced. It decreases accordingly.

The awake state of the LPWA device is the working state of the LPWA device, which mainly includes the transmission state of the LPWA device and the reception state of the LPWA device. The transmitting state of the LPWA device is the working state of the LPWA device uploading data information, and the receiving state of the LPWA device is the working state of the LPWA device receiving the downlink data information, both of which are data interaction with the base station.

The sleep state of the LPWA device is the inoperative state of the LPWA device, mainly including the IDLE state of the LPWA device and the PSM state of the LPWA device.

As shown in FIG. 2, in the present disclosure, the PLWA device mainly has four components: an LPWA device system 200, a power supply mode selection switch 201, a wireless chip 202, and a battery 203.

LPWA device system 200: used to determine whether the LPWA device needs to go from one operating state to another.

The power supply mode selection switch 201 is configured to determine, in the LPWA device system, that the LPWA device needs to enter another operating state from one operating state, and select a power supply mode required for the current operating state by closing the power supply mode selection switch.

The wireless chip 202 is configured to supply power by an energy provided by a wireless power supply device received by the radio frequency wireless transmission mode when the LPWA device is in a sleep state.

In specific implementation, the LPWA device collects the electromagnetic wave energy in the environment through the rectifying antenna. After the electromagnetic wave energy collected by the antenna passes through the post-transfer circuit in the wireless chip, the collected electromagnetic wave energy can be converted into electric energy by the conversion circuit, and then the converted electric energy can be LPWA. The device is powered and can also charge the battery configured for the LPWA device.

When the LPWA device is in the sleep state, the power converted by the conversion circuit is directly supplied to the LPWA device to maintain operation; when the LPWA device is in the awake state, the converted circuit power is transferred to the energy storage device, such as the battery provided by the LPWA device itself.

Battery 203: for providing an operating current to the LPWA device when it is in an awake state.

In general, the LPWA device can determine whether to enter the sleep state from the awake state by the following two methods.

1. It is determined whether the threshold state of the data transmission according to the sleep timer is determined to be required to enter the sleep state from the awake state.

Optionally, the LPWA device determines to complete a data transmission by:

In a specific implementation, the LPWA device pre-defines the protocol with the associated base station in advance to determine the time taken to perform a data transmission. When the sleep timer set by the LPWA device according to the protocol expires, that is, when a data transmission time has elapsed, the LPWA device determines that it needs to enter the sleep state from the awake state.

In this way, the duration of the data uploaded by the LPWA device is determined to be regular, and the power supply mode determined by the LPWA device can be determined in time to save the battery power loss.

For example, suppose the LPWA device needs to report the temperature of the pool every hour of every day, and the time for reporting is 1 minute. When the time for reporting the data of the LPWA device reaches 1 minute, the LPWA device determines that it needs to go to sleep from the awake state. State, the LPWA device enters a sleep state and is powered by wireless power.

Second, according to the length of time when the data is not sent and received and the set threshold time length, it is determined that the waking state needs to enter the sleep state.

Optionally, after the length of time that the LPWA device does not perform data transmission and reception reaches a set duration, it is determined that the awake state needs to enter a sleep state.

In the implementation, the LPWA device monitors the awake state to monitor the transmission of the data transmission, and counts the time after the data transmission is completed. When the LPWA device does not perform the data transmission and reception for a longer period than the LPWA device presets with the base station, the LPWA device determines that the The awake state goes to sleep.

In this way, the LPWA device determines whether it needs to enter the sleep state from the awake state according to the specific data transmission condition of the LPWA device, and thus can determine the power supply mode adopted according to the operation state of the LPWA device in time, thereby saving the loss of the battery power, and at the same time, determining whether it is necessary The transition from the awake state to the sleep state is determined based on the length of time during which the data is not transmitted and received, and the LPWA device is previously compared with the base station set threshold, so that even if a large amount of data needs to be transmitted, the data transmission can be completely completed.

For example, suppose that the LPWA device needs to report the temperature of the pool every hour of every day. The LPWA device sets the threshold with the base station in advance for 1 minute. At this time, the data transmission and reception time is more than 1 minute, and no data is transmitted or received. If the duration is greater than the LPWA device presets the threshold with the base station for 1 minute, the LPWA device determines that it needs to enter the sleep state from the awake state, and the LPWA device enters the sleep state to supply power by wireless power supply.

As shown in FIG. 3, the flow chart of the LPWA device entering the sleep state from the awake state in the embodiment of the present disclosure is as follows.

Step 300, the LPWA device is in an awake state;

Step 301, the LPWA device in the awake state determines whether to enter the sleep state by the awake state, and if so, step 202 is performed, otherwise, step 203 is performed;

Step 302, after the LPWA enters the sleep state from the awake state, stops power supply through the battery provided by the LPWA, and supplies power by using the energy provided by the wireless power supply device received by the radio frequency wireless transmission mode;

In step 303, the LPWA device maintains power supply with its own battery.

After the LPWA device enters the sleep state from the awake state, the LPWA device also continuously judges whether the LPWA device determines whether the sleep state is entered from the sleep state.

Optionally, the LPWA device determines whether the awake state is entered by the sleep state in response to the waking state entering the sleep state; and stopping the power supply provided by the wireless power supply device to supply power in response to entering the awake state by the sleep state, And use the battery equipped with it to supply power.

In the embodiment of the present disclosure, when the LPWA device is in the sleep state, it is determined whether the awake state is entered from the sleep state, and after entering the awake state from the sleep state, stopping the power supply provided by the wireless power supply device to supply power, and using the battery provided by itself Power is supplied, so that when the LPWA device is in the awake state, the power supply mode can be switched in time to provide sufficient current for the LPWA operation.

1. When the LPWA device receives an external stimulus, it determines that it needs to enter the awake state from the sleep state.

Optionally, after receiving the trigger interrupt, the LPWA device determines that it needs to enter the awake state from the sleep state.

During the implementation of the embodiment of the present disclosure, the LPWA device is stimulated by the outside world and receives the trigger interrupt. The LPWA device determines that the sleep state needs to be entered into the awake state by triggering the interrupt, so that the monitoring system can be effectively applied to enable the emergency event to be issued in time. alarm.

For example, suppose the LPWA device is a fire alarm. When a fire occurs, the fire alarm receives smoke stimuli, the internal circuit current of the fire alarm changes, the fire alarm detects the circuit current change, and it is determined that the LPWA device needs to enter the sleep state. The awake state, then wake up the fire alarm, the fire alarm system controls the power mode selection switch, uses battery power, the fire alarm works normally, and an alarm is issued.

Wherein, the trigger interrupt is a signal in the form of current or voltage formed by the LPWA device by the external stimulus itself, and the LPWA device detects the signal to determine that the LPWA device needs to enter the awake state from the sleep state.

2. The LPWA device determines that it needs to enter the awake state from the sleep state according to the set wake-up timer.

Optionally, the LPWA device determines that the waking state needs to be entered from the sleep state after the set wake-up timer expires.

In a specific implementation, the LPWA device determines whether it is necessary to enter the awake state from the sleep state by the set wake-up timer; thus, the long-lasting data monitoring can be excellently implemented, which is convenient for experimental research.

For example, suppose that there is currently a plant cultivation experiment that requires the LPWA device to measure the temperature data every 10 minutes and report the record. Thus, before the LPWA device performs this task, the wake-up timer must be set in advance so that the LPWA device can 10 minutes from sleep state to wake-up state, measure temperature and upload data, so LPWA equipment is very beneficial to achieve long-lasting data monitoring.

As shown in FIG. 4, the flow chart of the LPWA device entering the awake state from the sleep state in the embodiment of the present disclosure is as follows.

Step 400, the LPWA device is in a sleep state;

Step 401, the LPWA device in the awake state determines whether the awake state is entered from the sleep state; if yes, step 302 is performed; otherwise, step 303 is performed;

Step 402: After the sleep state enters the awake state, the LPWA stops power supply by using the energy provided by the wireless power supply device, and supplies power by using the battery provided by the LPWA;

In step 403, the LPWA device maintains power supply using the energy provided by the wireless power supply device received by the radio frequency wireless transmission mode.

As shown in FIG. 5, a schematic flowchart of a method for powering an LPWA device in an embodiment of the present disclosure.

Step 500, the LPWA device is in an awake state;

Step 501, the LPWA device in the awake state determines whether to enter the sleep state by the awake state, and if so, step 502 is performed, otherwise, step 503 is performed;

Step 502, after the LPWA enters the sleep state from the awake state, stops power supply through the battery provided by the LPWA, and supplies power by using the energy provided by the wireless power supply device received by the radio frequency wireless transmission mode;

Step 503, the LPWA device maintains power supply by using a battery equipped by itself;

Step 504, the LPWA device is in a sleep state;

Step 505, the LPWA device in the awake state determines whether the awake state is entered from the sleep state; if yes, step 506 is performed, otherwise, step 507 is performed;

Step 506, after the LPWA enters the awake state from the sleep state, stopping the power supply provided by the wireless power supply device, and supplying power by using the battery provided by the LPWA;

In step 507, the LPWA device maintains power supply using the energy provided by the wireless powering device received by the radio frequency wireless transmission.

Optionally, the LPWA device supplies power by using the energy provided by the wireless power supply device received by the radio frequency wireless transmission mode, and charges the battery with the energy provided by the wireless power supply device.

In a specific implementation, while the LPWA device supplies power by the wireless power supply device received by the radio frequency wireless transmission mode, if the battery configured by the LPWA device can receive and charge by the energy provided by the wireless power supply device, the LPWA device passes the radio frequency wireless The energy provided by the wireless powering device received by the transmission mode charges the battery. In this way, since the battery capacity of the battery configured by the LPWA device can be supplemented by wireless charging, the power of the battery configured by the LPWA device can be further reduced, thereby reducing the volume of the battery configured by the LPWA device. And because the battery can be charged by the energy provided by the wireless power supply device, this will make the life of the LPWA device extended.

In the present disclosure, the LPWA device is powered by a battery when in the awake state, and is powered by the energy provided by the wireless power supply device received by the radio frequency wireless transmission mode when the device is in a sleep state. Thus, when the LPWA device is manufactured, the configured battery is only required. The power required for the awake state can be satisfied without having to consider the amount of power consumed during sleep, which can reduce the size of the battery configured by the LPWA device. At the same time, since the LPWA device consumes 60%-70% of the power required by the LPWA device during sleep, the volume of the battery configured by the LPWA device can be greatly reduced.

Based on the same inventive concept, an LPWA device is also provided in an embodiment of the present disclosure, since the device is an LPWA device of the method in the embodiment of the present disclosure, and the principle of the device solving the problem is similar to the method, and thus the device is Implementation can refer to the implementation of the method, and the repetition will not be repeated.
