Description

Technical Field

[0001] The present invention relates to the technical field of power consumption control, and in particular to a power consumption management method and system for communication positioning equipment, and the communication positioning equipment. Background Art

[0002] The current positioning methods are satellite positioning and beacon positioning. Positioning services are widely used in communications, engineering, rescue and other aspects. Positioning information is uploaded to the server of the control center at regular intervals. The communication positioning equipment currently used is generally powered by rechargeable batteries, and its standby time is relatively short, generally 3-5 days, which is extremely inconvenient to use.

[0003] Even with the current advancements in battery technology, lithium-ion batteries are widely used and have become the primary energy source for outdoor portable devices and wilderness survival equipment. However, in some specialized scenarios, the fixed size of communication and positioning equipment makes it difficult to meet the required endurance requirements. For example, ships operating offshore for months at a time lack access to energy while maintaining essential communication with the outside world. Therefore, the endurance of communication and positioning equipment becomes paramount. However, given the fixed capacity of the equipment, the only effective way to increase endurance is to reduce its power consumption. Therefore, effectively managing the power consumption of communication and positioning equipment is a pressing challenge.

[0004] It can be seen that the above-mentioned existing communication positioning equipment still has certain defects in power consumption and usage time, and urgently needs to be further improved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a power consumption management method, system and communication positioning device for a communication positioning device, which solves the problems of high energy consumption and poor endurance in existing communication positioning devices, thereby overcoming the shortcomings of the existing technology.

[0006] To solve the above technical problems, the present invention provides a method for managing power consumption of a communication positioning device, which comprises the following steps:

[0007] When the communication positioning device receives a communication task, the CPU unit in the 4G+GNSS communication module specifies the corresponding communication mode according to the network environment and executes the corresponding power consumption management strategy according to the specified communication mode. The power consumption management strategy includes physical power consumption strategy and program power consumption strategy.

[0008] The positioning information is sent to the server according to the specified communication method. During the sending process, the physical power consumption strategy in the corresponding power consumption management strategy is first executed, and then the program power consumption strategy is executed;

[0009] The communication positioning device repeatedly executes the awakening state and the dormant state according to the preset sending cycle, and completes the sending of positioning information at a regular time.

[0010] As an improvement of the present invention, the communication mode includes a 4G communication mode and a short message communication mode.

[0011] As a further improvement of the present invention, the specific method of the program power consumption strategy is:

[0012] The corresponding program in each communication task is divided into several program segments according to different execution functions to form several task strategies. Each task strategy sets a wake-up flag and a sleep flag at the beginning and end of the program segment;

[0013] When executing according to the power consumption management strategy, the CPU unit will be awakened according to the wake-up flag of the called task strategy as long as there is at least one wake-up flag of the task strategy. When the sleep flags of all called task strategies are executed, the CPU unit will enter the sleep state.

[0014] As an improvement of the present invention, the specific method for the CPU unit in the 4G+GNSS communication module to determine the network environment is:

[0015] The 4G communication unit in the 4G+GNSS communication module sends a registration request to the network base station and determines whether there is a 4G network based on whether the correct reply information is received;

[0016] When the 4G communication unit receives a correct message reply, it determines that the communication positioning device is in a 4G network environment, and the communication mode is selected as 4G communication mode;

[0017] When the 4G communication unit cannot receive a correct message reply within a certain period of time, it is determined that the communication positioning device is in a 4G network-free environment, and the short message communication mode is selected at this time.

[0018] As a further improvement of the present invention, the power consumption management strategy executed by the communication positioning device in the process of sending positioning information to the server via 4G communication is:

[0019] After the enable pin of the power module receives a low level signal from the CPU unit in the 4G+GNSS communication module, the power module will cut off the power connection with the navigation satellite module and the acceleration module. At the same time, the 4G+GNSS communication module will close the IO interface connected to the navigation satellite module and the acceleration module.

[0020] The CPU unit of the 4G+GNSS communication module generates at least a task strategy for calling the 4G communication unit and the SIM card module, and adds a wake-up flag and a sleep flag to the task strategy for calling the 4G communication unit and the SIM card module respectively. After executing the task strategy for calling the 4G communication unit and the SIM card module, the CPU unit first determines whether all sleep flags have been executed. If all sleep flags have been executed, the CPU unit enters an ultra-low frequency working state, the CPU radio frequency unit keeps sending heartbeat signals periodically, and the timer runs the scheduled task.

[0021] As an improvement of the present invention, the power consumption management strategy executed by the communication positioning device in the process of sending positioning information to the server in a short message communication manner is:

[0022] After the enable pin of the power module receives a high level signal from the CPU unit in the 4G+GNSS communication module, the power module will connect to the power supply of the navigation satellite module and the acceleration module. At the same time, the 4G+GNSS communication module will at least close the IO interface connected to the 4G communication unit, the CPU radio frequency unit, and the SIM card module.

[0023] The CPU unit of the 4G+GNSS communication module generates at least a task strategy for calling the navigation satellite module and the acceleration module, and adds a wake-up flag and a sleep flag to the task strategy for calling the navigation satellite module and the acceleration module respectively. After executing the task strategy for calling the navigation satellite module and the acceleration module, the CPU unit first determines whether all sleep flags have been executed. If all sleep flags have been executed, the CPU unit enters an ultra-low frequency working state, and only the timer runs the scheduled task.

[0024] In addition, the present invention also discloses a power consumption management system for a communication and positioning device, which is used to execute the above-mentioned power consumption management method. The system includes a 4G+GNSS communication module, a navigation satellite module, an acceleration module, and a power supply module.

[0025] The power module is respectively connected to the navigation satellite module, the acceleration module, and the 4G+GNSS communication module. The 4G+GNSS communication module is provided with multiple groups of IO interfaces, of which at least one group of IO interfaces is connected to the enable pin in the power module; the 4G+GNSS communication module is communicated with the navigation satellite module through the UART_RX interface and the UART_TX interface; the 4G+GNSS communication module is communicated with the acceleration module through the I2SCL interface and the I2SDA interface.

[0026] As a further improvement of the present invention, the system also includes an indicator light module, a SIM card module and an antenna module. At least 5 groups of IO interfaces in the 4G+GNSS communication module are respectively connected to the indicator light module, and at least 4 groups of IO interfaces are respectively connected to the SIM card module. The 4G+GNSS communication module is connected to the antenna module through the GPS_ANT interface and the LET_ANT interface.

[0027] As a further improvement of the present invention, the 4G+GNSS communication module includes a 4G communication unit, a CPU unit, a CPU radio frequency unit and a timer, wherein the 4G communication unit is used to send positioning information in a 4G communication manner, the CPU unit is used to generate and execute task strategies, the CPU radio frequency unit is used to periodically send heartbeat signals to maintain communication between the communication positioning device and the server, and the timer is used to time the positioning information sending cycle.

[0036] Examples of the embodiments described in the present invention are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0038] This embodiment specifically discloses a power consumption management system for a communication and positioning device, which is used to execute the above-mentioned power consumption management method. The system includes a 4G+GNSS communication module, a navigation satellite module, an acceleration module, an indicator light module, a SIM card module, a power supply module, and an antenna module.

[0039] The power module is respectively connected to the navigation satellite module, the acceleration module, and the 4G+GNSS communication module. The 4G+GNSS communication module is provided with multiple groups of IO interfaces, wherein at least one group of IO interfaces is connected to the enable pin in the power module, at least five groups of IO interfaces are respectively connected to the indicator light module, and at least four groups of IO interfaces are respectively connected to the SIM card module; the 4G+GNSS communication module is communicated with the navigation satellite module through the UART_RX interface and the UART_TX interface; the 4G+GNSS communication module is communicated with the acceleration module through the I2SCL interface and the I2SDA interface; the 4G+GNSS communication module is connected to the antenna module through the GPS_ANT interface and the LET_ANT interface.

[0040] In more detail, the 4G+GNSS communication module includes a 4G communication unit, a CPU unit, a CPU radio frequency unit and a timer, wherein the 4G communication unit is used to send positioning information in a 4G communication manner, the CPU unit is used to generate and execute task strategies, the CPU radio frequency unit is used to periodically send heartbeat signals to maintain communication between the communication positioning device and the server, and the timer is used to time the positioning information sending cycle.

[0041] In addition, this embodiment also discloses a power consumption management method for a communication positioning device, which includes the following steps:

[0042] First, when the communication positioning device receives a communication task, the CPU unit in the 4G+GNSS communication module specifies the corresponding communication mode according to the network environment, and executes the corresponding power consumption management strategy according to the specified communication mode, wherein the power consumption management strategy includes a physical power consumption strategy and a program power consumption strategy; preferably, the communication mode described in this embodiment includes a 4G communication mode and a short message communication mode. In this embodiment, the 4G communication mode is implemented by a 4G communication unit integrated in the 4G+GNSS communication module, and the short message communication mode sends text messages to a global navigation satellite system, such as the Beidou satellite navigation system, the Global Positioning System, the GLONASS satellite navigation system, the Galileo satellite navigation system, etc., through the navigation satellite module.

[0043] In detail, the specific method for the CPU unit in the 4G+GNSS communication module in this embodiment to determine the network environment can preferably be determined by using the radio frequency unit to send a network registration signal. The specific method is:

[0044] The 4G communication unit in the 4G+GNSS communication module sends network registration information to the network base station and determines whether there is a 4G network based on whether the correct reply information is received;

[0045] When the 4G communication unit receives the correct reply information, it determines that the communication positioning device is in a 4G network environment, and the communication mode is selected as 4G communication mode;

[0046] When the 4G communication unit cannot receive the correct reply information within a certain period of time, it is determined that the communication positioning device is in a 4G network-free environment, and the short message communication mode is selected at this time.

[0047] Secondly, the positioning information is sent to the server according to the specified communication method. During the sending process, the physical power consumption strategy in the corresponding power consumption management strategy is first executed, and then the program power consumption strategy is executed;

[0048] The specific method of the program power consumption strategy in this embodiment is as follows:

[0049] The corresponding program in each communication task is divided into several program segments according to different execution functions to form several task strategies. Each task strategy sets a wake-up flag and a sleep flag at the beginning and end of the program segment;

[0050] When executing according to the power management strategy, according to the wake-up flag of the called task strategy, as long as there is at least one task strategy wake-up flag, the CPU unit will be awakened. When the sleep flags of all called task strategies are executed, the CPU unit will enter the sleep state. Figure 3As shown in the figure, after executing wake("A"), the system is awakened. After executing wake("B"), the system is awakened, which is the same as executing wake("A"). Then, after executing sleep("A"), the module will not sleep because sleep("B") has not been executed at this time. After executing sleep("B"), there is no wake and the module sleeps. Continuing to execute wake("C"), the module is awakened. After executing sleep("C"), the module sleeps.

[0051] Based on the aforementioned program power consumption strategy, in this embodiment, as long as the wakeup flag of a task strategy is executed, the entire module, namely the CPU unit, will be awakened; only when all sleep flags are executed will the module enter sleep mode. Therefore, in this embodiment, after generating different task strategies, the CPU unit can add wakeup and sleep flags to each task strategy. Executing any task strategy will awaken the CPU unit, and regardless of the number of task strategies, the CPU unit will enter sleep mode only when the sleep flags of all task strategies are executed. This method allows program tasks to adjust their sleep periods according to the task, eliminating the need to fully execute all tasks, thus reducing program runtime.

[0052] It can be explained in detail that when the communication positioning device sends the positioning information to the server via 4G communication, that is, by combining the physical power consumption strategy with the program power consumption strategy, the specific power consumption management strategy is:

[0053] First, after the enable pin of the power module receives a low level sent by the CPU unit in the 4G+GNSS communication module, the power module will cut off the power connection with the navigation satellite module and the acceleration module. At the same time, the 4G+GNSS communication module will close the IO interface connected to the navigation satellite module and the acceleration module. This step shuts down all physical devices related to short message communication in the device, reducing device energy consumption.

[0054] As for the program power consumption strategy, when the CPU unit of the 4G+GNSS communication module generates at least a task strategy for calling the 4G communication unit and the SIM card module, a wake-up flag and a sleep flag are first added to the task strategy for calling the 4G communication unit and the SIM card module respectively. In this way, when any of the above task strategies is executed, the CPU unit can be awakened. Only after all the task strategies for calling the 4G communication unit and the SIM card module are executed, that is, the CPU unit determines that all sleep flags have been executed, the CPU unit enters an ultra-low frequency working state. At the same time, in order to maintain normal 4G communication, the CPU radio frequency unit keeps sending heartbeat signals periodically, and the timer runs the scheduled task to execute the next positioning information sending task according to the preset period.

[0055] Similarly, when the communication positioning device sends positioning information to the server in a short message communication mode, the power consumption management strategy it implements is:

[0056] After the enable pin of the power module receives a high level sent from the CPU unit in the 4G+GNSS communication module, the power module will connect to the power supply connection with the navigation satellite module and the acceleration module. At the same time, the 4G+GNSS communication module will at least shut down the IO interface connected to the 4G communication unit, the CPU radio frequency unit and the SIM card module. This step shuts down the devices related to 4G communication, while the devices related to short message communication maintain normal operation, thereby ensuring that positioning information is sent normally and the equipment operates with minimal power consumption.

[0057] Correspondingly, the CPU unit of the 4G+GNSS communication module generates at least a task strategy for calling the navigation satellite module and the acceleration module, and adds a wake-up flag and a sleep flag to the task strategy for calling the navigation satellite module and the acceleration module respectively. After executing the task strategy for calling the navigation satellite module and the acceleration module, the CPU unit first determines whether all sleep flags have been executed. If all sleep flags have been executed, the CPU unit enters an ultra-low frequency working state, and only the timer runs the scheduled task.

[0058] To further illustrate, the physical power consumption strategy adopted in this embodiment includes strategies such as cutting off device power supply, turning off module output voltage, and turning off IO interface, which reduces device power consumption by reducing the number of execution devices and lowering voltage power.

[0059] Take the device execution process as an example, Figure 4As shown, when the device is in the 4G network coverage area, it gives priority to calling the 4G communication method to send positioning data. At this time, the program executes wake("4G") to wake up the CPU unit. The wake("4G") is the wake-up mark of the 4G communication unit. After sending the data, it executes sleep("4G") to enter the sleep mode. The sleep("4G") is the sleep mark of the 4G communication unit. At this time, the CPU unit is dormant and enters ultra-low frequency operation, while the CPU radio frequency unit works, periodically paging, and maintaining heartbeats to maintain network connection. At this time, the CPU unit current is only 4mA When the device is in an area without 4G network coverage, the Beidou communication module can be used to send data. At this time, executing wake("beidou") wakes the CPU. This wake("beidou") is the Beidou communication module's wake-up flag, and the CPU turns on the 5V power supply. After the Beidou communication module sends data, the 5V power supply is turned off. Executing sleep("beidou") enters sleep mode. The CPU's RF unit and SIM card module are both shut down, leaving only the CPU operating at minimum power consumption, drawing only 1mA to 2mA. When neither 4G nor Beidou networks are available, the CPU cyclically searches for both.

[0060] Finally, the communication and positioning device of this embodiment can repeat the above steps according to the preset sending period to complete the sending of positioning information on a regular basis.

[0061] Furthermore, this embodiment also discloses a communication positioning device, which includes the above-mentioned power consumption management system.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications based on the technical content disclosed above, which all fall within the scope of protection of the present invention.
