FIG. 3 is a schematic structural diagram of combining an Internet of Things terminal with an existing mobile terminal according to an embodiment of the present invention.

Preferred embodiment of the invention

The low-power IoT terminal structure provided by the present invention is shown in FIG. 1 and includes: an industry application module, a communication module, a control module, and a sleep management module, wherein:

The industry application module is used to collect, collect, and process IoT business data; the processing may be calculation or statistics, and the industry application module determines what to do according to the needs of the IoT business.

The communication module is configured to establish a transmission link with the network side, send the collected data or the collected and processed data to the network side, and receive the control command sent by the network side, and send the control command to the control module;

The control module is configured to control each module according to a control command sent by the network side; the control may modify the timer setting according to service characteristics, turn off the timer, or start the He is in industrial control and so on. Further, the control module sets a time when the sleep management module sleeps and/or wakes up according to a control command sent by the network side, and sets a time for the industry application module to collect data.

The sleep management module is used to control the time when the IoT terminal sleeps and wakes up, and when the terminal sleeps, at least the industrial application module and the communication module are turned off.

The time to sleep and wake up is determined by the IoT service, which can be set by the user or dynamically set by the network side. The sleep management module can control the time of sleep or wake-up by using a timer. For example, when the terminal is used as a gateway, the data collection time of the sensor is 1 day, and the sleep time of the IoT terminal can be set to 1 day, after the time is reached. The industry application module in the terminal is awakened to collect data collected by each sensor, and then the data is reported to the network side by the awakened communication module. Preferably, the working time is also set for the communication module. For example, if the working time of the communication module is set to 1 hour, after the time is reached, the communication module continues to sleep, and the communication module cannot receive the control command or other paging sent by the network side. Message. In addition to the timer, wake-up can also be triggered by a hardware interrupt, such as a user waking up the terminal by pressing a button.

Preferably, the sleep management module allows the control module and the communication module to enter the sleep mode, that is, the control module and the module also enter the sleep mode, that is, all the modules are turned off, and only the timer is kept in operation, and the timer setting time is reached. Wake up the sleep management module, and then wake up the other modules by the sleep management module. This will maximize the power savings.

Preferably, the terminal further includes a power management module, configured to record the battery usage information of the terminal, and send the battery usage information of the terminal to the network side through the communication module. The communication module usually reports the battery usage information when the IoT service data is reported, that is, it is reported when it is awakened.

Since IoT terminals are used as function modules such as sensors and gateways, they are generally fixed settings, and they do not need to report in real time when collecting, processing, and transmitting data. They only need to be collected and reported periodically, and most of them are idle. Therefore, considering that there is no communication service requirement between the two IoT services, it can be put to sleep, reduce the power consumption of the terminal and increase the power consumption time through the sleep and wake-up mechanism.

The network side device used in combination with the terminal includes at least a data collection processing module and a control command issuing module, where: The data collection and processing module is configured to save and process the collected data reported by the terminal; the control command issuing module is configured to send a control command to the terminal when the terminal is woken up.

The control command can be, for example, information such as a timer setting, a timer off, or other industrial control.

Preferably, the network side device further includes a terminal power control module, wherein the terminal power control module is configured to receive battery usage information reported by each terminal, and when the remaining battery power of a terminal battery is lower than a predetermined threshold, issue a police alarm to notify the work. The person replaces the battery of the terminal.

The network side device can perform intelligent control of the power source on the terminal according to the battery usage information reported by the terminal. For battery-powered IoT terminals, the number is large, the location is scattered, and there is no specific terminal power. If the power is updated or charged completely by region or batch, it will inevitably affect the efficiency of the Internet of Things. The terminal reports the battery usage information for power monitoring. For example, a collection system has 100 nodes (Internet of Things terminals). The network-side device can notify the staff to perform batch battery replacement or charging according to the battery usage information reported by each terminal, thereby eliminating the trouble of checking one node and avoiding The data caused by the dead battery cannot be collected.

Preferably, the network side device further includes a terminal scheduling module, which can reduce system congestion and improve system capability by performing intelligent dynamic control on the time and/or reporting period of the IoT terminal, and the terminal scheduling module constructs the scheduling content of the terminal. The control command is sent to each terminal through the control command issuing module.

The flow of implementing the above-mentioned Internet of Things terminal can be seen in Figure 2. When the timer in the sleep management module expires, after the IoT terminal is woken up, the industry application module in the terminal collects data and sends the collected IoT data. To the communication module; at the same time, the power management module also collects the battery usage information, and sends the battery usage information to the communication module; the communication module establishes a communication link with the network side, reports the Internet of Things service data, and the battery usage information of the terminal, if the network side When a control command is issued, the communication module sends the received control command to the control module, and the control module interprets the command, and implements setting or controlling other modules according to the content of the command; when the sleep time arrives, the sleep management module The industrial application module, the power management module, the control module, and the communication module all go to sleep. The sleep time may be the time controlled by the sleep timer, or the terminal automatically enters the sleep state to start the wake-up timer after all the operations are completed. The above IoT terminal can be integrated into an existing mobile terminal as a device, in order to drop

For example, the IS-95 system can extend the paging time and reduce the paging frequency by changing the parameters. In the IS-95 system parameter configuration, there is a paging channel indicator (Slot_Cycle-Index) to determine the frequency that the mobile station uses to determine the terminal "wake up": The length of time can be calculated by the following formula:

2 ^slot - ^CycleJndex x 1.28s

For example, the recommended value is 2, and the terminal wakes up every 5.12 seconds to achieve dynamic adjustment. The paging channel indicator can be determined jointly by the mobile station and the system. The mobile station has a Preferred Slot Cycle Index; the system side determines the maximum value (Maximum Slot Cycle Index); the paging channel indicator (Slot Cycle Index) takes Both are smaller values. So you can change these two values to achieve the effect of the adjustment, but the problem with this method is that both the phone and the network side make changes, and the maximum value is limited.

The following embodiments and in conjunction with FIG. 3 illustrate how to integrate the above-described Internet of Things terminal as a device into an existing mobile terminal. Specifically, an industrial application module, a control module, a communication module, a sleep management module, and the like are added to the terminal.

The industry application module is used to collect, collect, and process IoT business data; the industry application module is added at the application layer to meet the requirements of the IoT application to complete the normal IoT business.

The control module is used to complete the terminal timer management, and set the value of the timer according to the requirements of the Internet of Things service data. Its value can be converted to the sleep module hardware timer timeout as a wake-up trigger condition. The timer time period can be set by the initial value or dynamically by the network side application module. Control modules are also added at the application layer.

In order to obtain sensor information, a sensor interface is added for receiving corresponding sensor information. If the terminal itself integrates the sensor directly to operate the hardware.

The communication module is configured to establish a transmission link with the network side, send the collected data or the collected and processed data to the network side, and receive a control command sent by the network side, and send the control command to the control module. ; The sleep management module mainly completes terminal sleep management. The sleep management module determines whether the mobile phone is idle or idle according to a dynamic schedule maintained by the operating system. The sleep management module completes the sleep state by a hardware counter. There are hardware timers still working while sleeping, and other hardware is sleeping. Before the mobile phone idles into the sleep state, the idle time is converted into a value, and the counting completion wakes up the terminal.

In order to ensure that the sleep time is not disturbed by the outside world, the sleep wake-up trigger condition such as paging is turned off. The reason why the invention is turned off here is that the influence on the terminal is minimal, and the relevant part of the communication module protocol can be changed, but the terminal modification workload is large and unstable.

The application layer timer is set to one of the wake-up terminal trigger conditions (there are still other trigger conditions, such as interrupt events such as user buttons). In this way, the terminal can be triggered by a timer or user intervention to achieve power saving and low power consumption.

In order to cooperate with this management process, the network side application module must be completed to perform the corresponding functions. Such as the terminal's timer dynamic control, terminal status collection and control functions.

The invention is particularly suitable for a multi-point fixed collection system, using a battery-powered IoT service system. Take the water quality collection system as an example, use 100 fixed collection points, and report it to the network side once a day. You can change the reporting period and reporting time. The IoT terminal is used for the sample collection. The IoT terminal itself integrates the sensor. It takes 2 minutes for the sensor to complete the water quality collection. After the completion of the collection, the processing is completed according to the predetermined procedure, and 4 notifications are formed. 100 IoT terminals are powered by batteries.

The network side device uses the gateway to interact with the collection terminal. It includes a data collection and processing module, a control command delivery module, a collection scheduling module, and a battery management module.

The advantages of using the invention are:

The low-power design of the IoT terminal is completed with minimal changes in the terminal. Although the IoT terminal is in the on-off state, it only works during the collection time (2 minutes per day) and the reporting time. Other times are in the sleep state, which minimizes the power consumption of the terminal and prolongs the battery life.

Dynamic control of terminal collection time and reporting period can reduce gateway congestion and complete special and temporary collection tasks.

Battery capacity monitoring for 100 terminals according to the remaining battery capacity reported by the IoT terminal Control. The network side device can notify the staff to perform batch battery replacement or charging according to the battery usage information reported by each terminal, thereby eliminating the trouble of checking one node and avoiding data collection due to lack of power of the battery.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.

Industrial applicability

The invention increases the sleep and active wake-up mechanism, so that the Internet of Things terminal is in a sleep state most of the time, and wakes up the terminal to enter a normal working state according to the requirements of the service and completes the scheduled work. In addition, the present invention can also enable the network side application module to complete the power supply intelligent control of the Internet of Things terminal by reporting the maintenance information of the Internet of Things terminal, such as the power information, for example, according to the power information guide, when to change the battery of the Internet of Things terminal or The maintenance work of the battery such as charging, thereby saving the management and maintenance cost of the Internet of Things terminal.
