Description

A sleep mode data sending and receiving control method for LoRa modules

Technical field

The present invention relates to the technical field of wireless communication in low power consumption mode, and in particular to a sleep mode data transmission and reception control method of a LoRa module.

Background technique

The LoRa serial port transparent communication module has the characteristics of compact structure and low power consumption. The module is designed to industrial standards and uses high-performance industrial-grade chip solutions to realize LoRa network data transmission, which can quickly develop and deploy LoRa networks to achieve long-distance, low-power control and data collection purposes. Using this module in your application can significantly reduce product development time.

At present, in order to adapt to different application scenarios, LoRa modules usually have multiple working modes. The common ones are: normal transceiver mode, sleep mode, hibernation mode, etc. The working mode definitions of LoRa modules produced by different companies are different. No matter which way you say it, the sleep mode represents the lowest power consumption working mode.

Sleep mode means that the LoRa module enters the lowest power consumption. The components that work in this mode have the SPI interface: in the low-power mode, the pre-main control chip wakes up the RF chip through the SPI interface and enters the standby mode. Regulator is a voltage regulator used to ensure the voltage required by the SPI interface. The power source comes from VBAT, which is the battery voltage. RC64K low-frequency crystal oscillator circuit: used to ensure the reference clock required by the SPI interface. In SLEEP mode, most circuits of the radio frequency chip are in sleep state, and only the SPI interface is accessible. In fact, when accessing SPI, the main control chip will set the NSS bit, and this signal can wake up the radio frequency chip from sleep mode.

However, under extreme working conditions, the power supply battery of the battery-powered LoRa module may not be able to complete the wake-up from sleep mode, or may not be able to complete a normal transmission after waking up. The cause of this working condition may be abnormal vibration leading to heavy weight. Uncontrollable displacement of the LoRa module power supply battery causes power supply interruption. How to ensure the transmission of key data collected by the sensor under this working condition is an urgent technical problem that needs to be solved.

Contents of the invention

In order to solve the technical problems in the prior art, the present invention provides a sleep mode data transmission and reception control method of a LoRa module. Adopt the following technical solutions:

A sleep mode data sending and receiving control method for a LoRa module, including the following steps:

Step 1. The main control chip of the LoRa module obtains the battery power data of the battery management chip at every set time;

Step 2: Set the capacitor energy storage range threshold. When the main control chip determines that the power supply battery is within the capacitor energy storage range threshold, the main control chip controls the capacitor charging circuit to open, and the power supply battery supplies power to the energy storage capacitor through the capacitor charging circuit. The capacitor can store the set power;

Step 3. The main control chip controls the LoRa module to enter sleep mode. In the sleep mode, set the serial port to be in working state. When the serial port detects data, the main control chip communicates with the battery management chip to confirm the power supply battery power data. If the main control chip determines that the power supply If the battery power data is greater than or equal to the wake-up threshold, the main control chip controls the LoRa antenna module to wake up the LoRa module and send the serial port data wirelessly;

Step 4. If the main control chip determines that the power supply battery power data is less than the wake-up threshold, the main control chip controls the energy storage capacitor to connect to the power supply, and then controls the LoRa antenna module to wake up the LoRa module to wirelessly send the serial port data.

By adopting the above technical solution, during normal power supply, that is, when the main control chip determines that the power of the power supply battery is within the capacitor energy storage range threshold by collecting the detection data of the battery management chip, the capacitor energy storage range threshold means that the power supply battery is at a higher level. In the power state, energy needs to be stored in the energy storage capacitor at this time. The stored energy generally occupies a small amount of power in the power supply battery and will not have a major impact on the normal operation of the power supply battery. The power stored in the energy storage capacitor can last longer. long time;

After entering the sleep mode, the serial port and the main control chip are directly connected. When the serial port detects data, the main control chip can wake up the LoRa antenna module to send the received data. The power needs to be confirmed before sending. Once the In extreme situations where the battery is extremely low, if you still perform the action of waking up the LoRa antenna module to send the received data, it is likely to cause the transmission to fail or even cause data loss;

Therefore, power detection is performed first. When the main control chip determines that the battery power data is less than the wake-up threshold, that is, when a battery abnormality occurs, it cannot ensure that the LoRa antenna module is supported for transmission. At this time, the energy storage capacitor that has completed energy storage needs to be connected. The energy storage capacitor replaces the power supply battery for power supply, which at least ensures that the LoRa antenna module completes the current data transmission, solves the problem of normal data transmission under extremely low-power power supply batteries, and avoids the risk of data loss.

Optional, assume that the standard power value of the power supply battery is P, and the capacitor energy storage range threshold is 90%P-P.

By adopting the above technical solution, 90%P-P is the power value of the power supply battery at the initial stage of use. The energy storage capacitor is stored at this time, which has little impact on the normal power supply of the power supply battery.

Optional, the wake-up threshold is 1%P of the power value of the power supply battery.

By adopting the above technical solution, through the power supply of the power supply battery, in some low-power LoRa module applications, theoretically it can meet the continuous power supply for 3-5 years. When the power of the power supply battery is less than 1%P, the problem usually occurs. In the event of an abnormal situation or the duration is too long, the power usually lower than 1%P cannot ensure that the LoRa antenna module can complete a data transmission. At this time, an energy storage capacitor is required for power supply.

Optionally, step 5 is also included. The LoRa module uses energy storage capacitor to power the LoRa antenna module. After sending the serial port data, it sends a battery abnormality data packet to the LoRa network control center. The main control chip controls the LoRa module to enter sleep mode again.

By adopting the above technical solution, after data transmission is completed using energy storage capacitor power supply, a battery abnormal data packet needs to be sent to the LoRa network control center to notify the remote staff of the abnormal status of the LoRa module. The LoRa network control center receives After the battery abnormal data packet, an alarm module should also be set up. The alarm module will alarm and remind the staff to deal with it in time. After sending the data, the main control chip should control the LoRa module to enter sleep mode again to save power as much as possible.

Optionally, after the main control chip wakes up the LoRa antenna module of the LoRa module in sleep mode, the baud of the LoRa antenna module is less than or equal to 9600bps.

By adopting the above technical solution, when the baud rate of the LoRa antenna module is less than or equal to 9600bps, it can be realized in the sleep mode that when the serial port detects data and needs to be sent, the main control chip only wakes up the LoRa antenna module. Implement data transmission in power consumption mode.

Optionally, in step 2, the energy stored in the energy storage capacitor does not exceed 2% of the standard energy value of the power supply battery, which is P.

By adopting the above technical solution, usually under the energy storage condition of 2%P power, the energy storage capacitor can support the LoRa module to work for at least 1 week, and the charging and discharging process of the container is always a physical process and there is no chemical reaction. Therefore, the performance is stable, which is different from batteries that use chemical reactions. When not in use, the battery can theoretically last for more than 1 year.

Optionally, implement data transceiver control in sleep mode based on a low-power LoRa module. The low-power LoRa module includes a main control chip, a battery management chip, a power supply module, a pin module, a serial port, and a LoRa antenna module;

The power supply module includes a power supply battery, a first electronically controlled switch, a capacitor charging circuit, an energy storage capacitor and a second electronically controlled switch. The battery management chip collects the power information of the power supply battery and communicates with the main control chip.

The energy storage capacitor is connected through the second electronically controlled switch to power each electrical device. The main control chip controls respectively The execution actions of the first electronically controlled switch and the second electronically controlled switch are achieved by turning on the first electronically controlled switch to realize charging of the energy storage capacitor through the capacitor charging circuit, and by turning on the second electronically controlled switch to realize the energy storage capacitor. Provide power to various electrical devices;

The minimum baud rate used by the serial port is lower than 9600bps, the serial port is directly connected to the main control chip, and when the baud rate used by the serial port is less than or equal to 9600bps, user data is received and responded to in sleep mode without additional wake-up operations;

The LoRa antenna module is communicatively connected to the main control chip through the pin module. The main control chip controls the execution actions of the LoRa antenna module and controls the operating baud rate of the LoRa antenna module.

By adopting the above technical solution, the electronically controlled PMOS tube can realize the on-off control of the circuit under the control of the main control chip, with extremely low power consumption. The power supply battery can supply power to the energy storage capacitor through the capacitor charging circuit. Under the control of the main control chip When the first electronically controlled switch is turned on, the energy storage capacitor can be charged. The charging time is controllable. The supercapacitor can generally be charged in a few seconds without affecting the normal operation of the low-power LoRa module. The second electronically controlled switch By turning on, the supercapacitor can be used to power the entire low-power LoRa module to meet the power supply needs in extreme low-power battery modes. It can achieve more stable power supply backup needs by using only one power supply battery. Its effect is different from Use the backup battery mode, because the extremely low power of the power supply battery is likely to cause the same situation in the backup battery, such as severe vibration. The weight of the battery is much greater than the capacitor, so the backup status of the supercapacitor is unstable. Better than battery backup.

Optionally, the serial port is a low-power UART communication serial port. The receiving end is used to connect to the data source, and the sending end is directly connected to the main control chip. The baud rate is adjustable between 1200bps and 115200bps.

By adopting the above technical solution, the serial port uses a low-power UART communication serial port, which supports adjustable baud rate and a setting range of 1200bps to 115200bps. When the baud rate is not higher than 9600bps, it can receive and respond to the user's serial port data in the sleep state without additional wake-up operations. When the baud rate is higher than 9600bps, you need to operate the wakeup pin to wake up the module.

Optionally, the pin module includes a sending status indication pin, a receiving status indication pin, an AT configuration pin, a module serial port input pin, a module serial port output pin, a module wake-up pin, a module reset pin, and a power input pin. pins, RF antenna interface pins, startup mode selection pins and multiple reserved pins;

The serial port sends data to the main control chip through the module serial port input pin, and the main control chip sends command data to the serial port through the module serial port output pin;

When the power supply battery is normally powered, the main control chip controls the baud of the LoRa antenna module to be less than or equal to 9600 bps. It can be realized in the sleep mode that the serial port detects data that needs to be sent. At this time, the main control chip only wakes up the LoRa antenna module, which can realize data transmission in the sleep mode and low power consumption mode, realizing ultra-low power consumption data transmission in the sleep mode;

When the power supply battery is ultra-low, the use of supercapacitors that complete energy storage for power supply can at least ensure that the LoRa antenna module completes the current data transmission, solving the problem of normal data transmission under extremely low-power power batteries and avoiding the risk of data loss.

The embodiment of the present invention discloses a sleep mode data transmission and reception control method of a LoRa module.

Referring to Figures 1-3, Embodiment 1, a sleep mode data transmission and reception control method of a LoRa module, includes the following steps:

Step 1: The main control chip 1 of the LoRa module obtains the power data of the power supply battery 3 of the battery management chip 2 at every set time;

Step 2, set the capacitor energy storage range threshold. When the main control chip 1 determines that the power of the power supply battery 3 is within the capacitor energy storage range threshold, the main control chip 1 controls the capacitor charging circuit 4 to open, and the power supply battery 3 passes through the capacitor charging circuit 4. The energy storage capacitor 5 supplies power, and the energy storage capacitor 5 stores the set power;

Step 3. The main control chip 1 controls the LoRa module to enter sleep mode. In the sleep mode, set the serial port 6 to be in the working state. When the serial port 6 detects data, the main control chip 1 communicates with the battery management chip 2 to confirm the power data of the power supply battery 3. If the main control chip 1 determines that the power data of the power supply battery 3 is greater than or equal to the wake-up threshold, the main control chip 1 controls the LoRa antenna module 7 to wake up the LoRa module and wirelessly transmit the data from the serial port 6;

Step 4, if the main control chip 1 determines that the power data of the power supply battery 3 is less than the wake-up threshold, the main control chip 1 controls the energy storage capacitor 5 to connect to the power supply, and then controls the LoRa antenna module 7 to wake up the LoRa module to wirelessly send the data from the serial port 6 .

During normal power supply, that is, when the main control chip 1 determines that the power of the power supply battery 3 is within the capacitor energy storage range threshold by collecting the detection data of the battery management chip 2, the capacitor energy storage range threshold means that the power supply battery 3 is in a relatively high power state. At this time, energy needs to be stored in the energy storage capacitor 5. The energy stored in the energy storage capacitor 5 generally occupies a small amount of power in the power supply battery 3 and will not have a major impact on the normal operation of the power supply battery 3. The energy stored in the energy storage capacitor 5 can last for a longer period of time;

After entering the sleep mode, the serial port 6 is directly connected to the main control chip 1. When the serial port 6 detects data, the main control chip 1 can wake up the LoRa antenna module 7 to send the received data. This needs to be done before sending. Battery confirmation. Once an extreme situation of extremely low battery occurs, if the action of waking up the LoRa antenna module 7 to send the received data is still performed, it is likely to cause the transmission to fail or even cause data loss;

Therefore, power detection is performed first. When the main control chip 1 determines that the power data of the power supply battery 3 is less than the wake-up threshold, that is, when a battery abnormality occurs, it cannot ensure that the LoRa antenna module 7 is supported for transmission. At this time, the storage device that has completed energy storage needs to be The energy capacitor 5 is connected to the power supply, and the energy storage capacitor 5 replaces the power supply battery 3 for power supply. This can at least ensure that the LoRa antenna module 7 completes the current data transmission, which solves the problem of normal data transmission under the extremely low-power power supply battery 3 and avoids the risk of data loss. .

Embodiment 2, assume that the standard electric quantity value of the power supply battery 3 is P, and the capacitor energy storage range threshold is 90%P-P.

90%P-P is the power value of the power supply battery 3 at the initial stage of use. At this time, the energy storage capacitor 5 is stored, which has little impact on the normal power supply of the power supply battery 3.

In Embodiment 3, the wake-up threshold is 1%P of the power value of the power supply battery 3 .

Through the power supply of power supply battery 3, in some low-power LoRa module applications, it can theoretically meet the continuous power supply for 3-5 years. When the power of power supply battery 3 is less than 1%P, an abnormal situation usually occurs. Or the duration is too long, and the power usually lower than 1%P cannot ensure that the LoRa antenna module 7 can complete a data transmission. At this time, the energy storage capacitor 5 needs to be used for power supply.

Embodiment 4 also includes step 5. The LoRa module uses the energy storage capacitor 5 to power the LoRa antenna module 7. After sending the data from the serial port 6, it sends a battery abnormality data packet to the LoRa network control center. The main control chip 1 controls the LoRa module to enter again. Sleep mode.

After data transmission is completed using energy storage capacitor 5, a battery abnormality data packet needs to be sent to the LoRa network control center to notify the remote staff of the abnormal status of the LoRa module. The LoRa network control center receives the battery abnormality data packet. Finally, an alarm module should be set up. The alarm module will alert the staff to deal with it in time. After sending the data, the main control chip 1 should control the LoRa module to enter sleep mode again to save power as much as possible.

Embodiment 5: After the main control chip 1 wakes up the LoRa antenna module 7 of the LoRa module in the sleep mode, the baud of the LoRa antenna module 7 is less than or equal to 9600 bps.

When the baud of the LoRa antenna module 7 is less than or equal to 9600bps, it can be implemented in the sleep mode. When the serial port 6 detects data and needs to be sent, the main control chip 1 only wakes up the LoRa antenna module 7, which can reduce power consumption in the sleep mode. Data is sent in this mode.

Embodiment 6, in step 2, the energy stored in the energy storage capacitor 5 does not exceed 2% of the standard electrical energy value of the power supply battery 3, which is P.

Usually, under the energy storage condition of 2%P power, the energy storage capacitor 5 can support the LoRa module to work for at least 1 week, and the charging and discharging process of the container is always a physical process and there is no chemical reaction. Therefore, the performance is stable, which is different from batteries that use chemical reactions. When not in use, the battery can theoretically last for more than 1 year.

Embodiment 7 implements data transmission and reception control in sleep mode based on a low-power LoRa module. The low-power LoRa module includes a main control chip 1, a battery management chip 2, a power supply module, a pin module 10, a serial port 6 and a LoRa antenna module 7;

The power supply module includes a power supply battery 3, a first electronic control switch 8, a capacitor charging circuit 4, an energy storage capacitor 5 and a second electronic control switch 9. The battery management chip 2 collects the power information of the power supply battery 3 and communicates with the main control chip 1 connection, the power supply battery 3 supplies power to each electrical device, and supplies power to the energy storage capacitor 5 through the first electronically controlled switch 8 and the capacitor charging circuit 4. The energy storage capacitor 5 is connected through the second electronically controlled switch 9 to power each electrical device. The main The control chip 1 controls the execution of the first electronically controlled switch 8 and the second electronically controlled switch 9 respectively. By turning on the first electronically controlled switch 8, the energy storage capacitor 5 is charged through the capacitor charging circuit 4. The second electronic control switch 9 is turned on to realize that the energy storage capacitor 5 supplies power to each electrical device;

The minimum baud rate used by serial port 6 is lower than 9600bps. Serial port 6 is directly connected to the main control chip 1. When the baud rate used by serial port 6 is less than or equal to 9600bps, it receives and responds to user data in sleep mode without additional wake-up operations. ;

The LoRa antenna module 7 is communicatively connected to the main control chip 1 through the pin module 10. The main control chip 1 controls the execution of the LoRa antenna module 7 and controls the operating baud rate of the LoRa antenna module 7.

The first electronically controlled switch 8 and the second electronically controlled switch 9 are both electronically controlled PMOS tubes, and the energy storage capacitor 5 is a supercapacitor. The first electronically controlled switch 8 , the second electronically controlled switch 9 and the energy storage capacitor 5 are all welded. The method is connected to the circuit board of the low-power LoRa module; the LoRa antenna module 7 is the LoRa wireless spread spectrum module SX1276.

The electronically controlled PMOS tube can realize the on-off control of the circuit under the control of the main control chip 1, with extremely low power consumption. The power supply battery 3 can supply power to the energy storage capacitor 5 through the capacitor charging circuit 4. Under the control of the main control chip 1 , the energy storage capacitor 5 can be charged when the first electronic control switch 8 is turned on, and the charging time is controllable. The supercapacitor can generally be charged in a few seconds, without affecting the normal operation of the low-power LoRa module. The second electronic control Turning on the switch 9 allows the supercapacitor to power the entire low-power LoRa module, meeting the power supply requirements of the extreme power supply battery 3 in ultra-low power mode, and achieving a more stable power supply backup requirement using only one power supply battery 3. The effect is different from the mode of using a backup battery, because the extremely low power of the power supply battery 3 is likely to cause the same situation of the backup battery, such as severe vibration. The weight of the battery is much greater than the capacitor, so the supercapacitor The stability of the backup situation is better than that of the backup battery.

Serial port 6 is a low-power UART communication serial port. The receiving end is used to connect to the data source, and the sending end is directly connected to the main control chip 1. The baud rate is adjustable between 1200bps and 115200bps.

Serial port 6 uses a low-power UART communication serial port, supports adjustable baud rate, and the setting range is 1200bps to 115200bps. When the baud rate is not higher than 9600bps, it can receive and respond to the user's serial port data in the sleep state without additional wake-up operations. When the baud rate is higher than 9600bps, you need to operate the wakeup pin to wake up the module.

Embodiment 8, the pin module 10 includes a sending status indication pin, a receiving status indication pin, an AT configuration pin, a module serial port input pin, a module serial port output pin, a module wake-up pin, a module reset pin, and a power input. pins, RF antenna interface pins, startup mode selection pins and multiple reserved pins;

The main control chip 1 communicates with the LoRa antenna module 7 through the radio frequency antenna interface pin.

The low-power LoRa module adopts a low-power serial port design and supports an over-the-air wake-up mechanism (corresponding to LCP parameters: link monitoring cycle). Corresponding usage scenarios:

1. If you only upload without receiving, you can configure the LCP to the maximum (that is, full OXFFFF, unit second), and the module will automatically go into deep sleep when there is no serial port input. When the serial port has a data port, it automatically wakes up and pushes data. Therefore, HL9 not only supports sending data under low power consumption, but can also operate using AT commands. Low-power serial port requires baud rate ≤ 9600;

2. If uplink and downlink are required and the downlink pattern is unknown, the module needs to receive it at any time. If there is no power consumption requirement, the default LCP configuration is 0, which is transparent transmission continuous reception mode, similar to LoRaWAN ClassC. If there are power consumption requirements, you need to consider both power consumption and reception by configuring the LCP value. LCP is a sleep cycle. When the cycle is over, LoRa signal monitoring is turned on. The default granularity is 1 second, and the shortest wake-up response is 1 second. If you need a faster wake-up cycle, you can refer to HL9-SDK for secondary development and programming. The faster it wakes up, the shorter the sleep time, and the higher the frequency of wake-up, the higher the power consumption.

3. If uplink and downlink are required, and the downlink is sent and then received, that is the LoRaWAN ClassA method. The old version can be used to wait for a period of time to receive after the sending is completed, then actively sleep, and cycle the operation again when there is a new sending request. Supports receiving window configuration, configure the receiving window through the command AT+RXW (the function is to enable RXW seconds to receive after the transmission is completed. Note that this function requires configuring LCP because the purpose of opening the receiving window is to allow the module to enter sleep after the window time is exceeded to save power consumption) .

The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be covered by the scope of protection of the present invention. Inside.
