Description

Technical Field

[0001] This invention relates to the field of digital agriculture technology, specifically to a hot standby management method and system for digital agriculture IoT terminals based on the principle of entropy reduction. Background Technology

[0002] The development of digital agriculture is progressing rapidly, with the Internet of Things (IoT) technology finding significant and widespread application. IoT terminals are a key component of digital agriculture solutions; various terminals are connected to the network center in a distributed manner, undertaking functions such as data collection, communication, driving, and processing.

[0003] In current digital agriculture IoT terminal configurations, information connections for terminal objects include both discrete and continuous types. For discrete terminals, operations such as data acquisition, communication, processing, and driving can be discontinuous, and real-time requirements are naturally lower. However, for continuous terminals, not only is high real-time performance required, but also seamless long-term interface communication for data acquisition, communication, processing, and driving. To meet long-term continuous management requirements, a single-interface IoT terminal is often insufficient. A dual-set design with parallel interfaces is typically used, and cold or hot standby is employed to switch to the other set of terminals for terminal object management in the event of a single terminal failure.

[0004] If discontinuous interfaces occur during the management of continuous terminal objects, such as discontinuous inputs (including data acquisition inputs and communication inputs), it will lead to untimely updates of input information; if discontinuous outputs occur, it will cause interruptions in external control. In the high-requirement terminal management of digital agriculture, such as pressure control, concentration control, and light-sensitive control, this discontinuity will cause control imbalance, directly affecting the growth environment of agricultural crops; prolonged imbalance can also cause terminal equipment to be under overstress, resulting in damage.

[0005] Based on the above specific requirements and impact analysis, the following problems exist in the management of agricultural IoT terminal devices for continuous terminal applications:

[0006] 1. The management system lacks a backup design, relying solely on the basic reliability of a single system to maintain continuous management. Hardware failures or software malfunctions will directly lead to the loss of terminal management; only by replacing and restarting the management system can management and control be restored.

[0007] 2. Although the management system incorporates a hot standby design, its fault detection coverage is limited. It relies solely on software to detect the status of peripheral circuits, but it cannot detect software malfunctions, thus failing to trigger a switchover. This results in the fault state persisting, and the management of IoT terminals remaining out of control.

[0008] 3. Although the management system has a hot standby design and some non-independent detection for software anomalies, the detection coverage is limited, the switching time is long, or the uniqueness of the interface during the switching process cannot be guaranteed. This causes both the main control module and the backup module to become the host, and dual host control will also lead to loss of control over the management of IoT terminals. Summary of the Invention

[0009] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the purpose of the present invention is to provide a digital agriculture Internet of Things terminal hot standby management method and system based on the entropy reduction principle, so as to improve the overall reliability of the system.

[0010] The first aspect of this invention discloses a hot standby management method for digital agriculture IoT terminals based on the principle of entropy reduction, which includes the following steps:

[0011] The system receives life signals sent by the first control unit and the second control unit. When both life signals are valid, it selects one of the first control unit and the second control unit as the host and connects the corresponding interface of its control module to the interface of the agricultural Internet of Things continuous terminal object. The other of the first control unit and the second control unit serves as the backup unit.

[0012] The system monitors the life signals emitted by the host and the backup unit in real time. When the life signal emitted by the host is invalid and the life signal emitted by the backup unit is valid, the backup unit is used as the new host unit, and the corresponding interface of its control module is connected to the interface of the agricultural IoT continuous terminal object.

[0013] In a preferred embodiment, when the life signal emitted by the main unit is invalid, the backup unit is used as the new main unit, including:

[0014] When a falling edge from high to low is detected in the life signal emitted by the host, it is determined that the life signal emitted by the host is invalid, triggering the electronic selection switch to switch to the backup unit, so that the backup unit becomes the new host, and the corresponding interface of the control module of the new host is connected to the interface of the agricultural Internet of Things continuous terminal object.

[0015] In a preferred embodiment, the method further includes:

[0016] Restart the host machine whose life signal is invalid, and use the restarted host machine as the new backup machine.

[0017] In a preferred embodiment, the control module of the first control unit or the second control unit generates an ordered excitation signal, including:

[0018] The control module generates an interrupt signal with a preset duration through a built-in timer, and sends the interrupt signal to the interrupt service module for processing. A dynamic baseband code is generated in each cycle.

[0019] The timing monitoring module enables the output of the dynamic baseband code, making it serve as the ordered excitation signal.

[0020] In a preferred embodiment, the energy storage module includes an entropy difference detection module, an inverter module, an energy pool, and a load; the ordered excitation signal is converted into a life signal based on entropy difference detection through the corresponding energy storage module, including:

[0021] The entropy difference detection module receives the ordered excitation signal and detects the ordered excitation signal;

[0022] When an entropy reduction signal is detected, the ordered excitation signal is valid. The entropy reduction signal is then used to generate an AC signal, which is used as the input signal of the inverter module. The AC signal is then converted into a DC voltage signal by the drive source to charge the energy pool. The entropy reduction signal also enables the control switch between the energy pool and the load to close, and the energy pool outputs a life signal through the load.

[0023] When the entropy increase signal is detected, the ordered excitation signal becomes invalid, and the control switch between the energy pool and the load is disconnected, so the energy storage module does not output a life signal.

[0024] The second aspect of the present invention discloses a digital agricultural Internet of Things (IoT) terminal hot standby management system based on the entropy reduction principle, characterized in that it includes a first control unit, a second control unit, a switching strategy module, and an agricultural IoT continuous terminal object.

[0025] The switching strategy module receives life signals sent by the first control unit and the second control unit. When both life signals are valid, one of the first control unit and the second control unit is selected as the host and its control module interface is connected to the interface of the agricultural Internet of Things continuous terminal object. The other of the first control unit and the second control unit is used as the backup.

[0026] The switching strategy module detects the life signals emitted by the host and the standby in real time. When the life signal emitted by the host is invalid and the life signal emitted by the standby is valid, the standby is used as the new host, and its control module interface is connected to the interface of the agricultural IoT continuous terminal object.

[0027] The life signal is generated by the control module of the first control unit or the second control unit into an ordered excitation signal, and then converted into a life signal based on entropy difference detection by the corresponding energy storage module.

[0028] In a preferred embodiment, when the life signal emitted by the main unit is invalid, the backup unit is used as the new main unit, including:

[0029] When the switching strategy module detects that the life signal emitted by the host forms a falling edge from high level to low level, it determines that the life signal emitted by the host is invalid, triggers the electronic selection switch to switch to the standby unit, so that the standby unit becomes the new host, and connects the corresponding interface of the control module of the new host to the interface of the agricultural Internet of Things continuous terminal object.

[0030] In a preferred embodiment, the switching strategy module also restarts the host with invalid life signal and uses the restarted host as a new backup host.

[0031] In a preferred embodiment, the control module of the first control unit or the second control unit generates an ordered excitation signal, including:

[0032] The control module generates an interrupt signal with a preset duration through a built-in timer, and sends the interrupt signal to the interrupt service module for processing. A dynamic baseband code is generated in each cycle.

[0033] The timing monitoring module enables the output of the dynamic baseband code, making it serve as the ordered excitation signal.

[0034] In a preferred embodiment, the energy storage module includes an entropy difference detection module, an inverter module, an energy pool, and a load; the ordered excitation signal is converted into a life signal based on entropy difference detection through the corresponding energy storage module, including:

[0035] The entropy difference detection module receives the ordered excitation signal and detects the ordered excitation signal;

[0036] When an entropy reduction signal is detected, the ordered excitation signal is valid. The entropy reduction signal is then used to generate an AC signal, which is used as the input signal of the inverter module. The AC signal is then converted into a DC voltage signal by the drive source to charge the energy pool. The entropy reduction signal also enables the control switch between the energy pool and the load to close, and the energy pool outputs a life signal through the load.

[0037] When the entropy increase signal is detected, the ordered excitation signal becomes invalid, and the control switch between the energy pool and the load is disconnected, so the energy storage module does not output a life signal.

[0038] Compared with existing technologies,

[0039] Addressing the problems inherent in traditional continuous management of agricultural IoT terminals, this invention utilizes the principle of entropy reduction during normal operation and entropy increase driven by faults. Its beneficial effects are as follows:

[0040] 1. It has a hot standby redundancy architecture, and the two control units can automatically switch without manual intervention, which significantly improves the overall reliability of the system and will not cause the system to fail due to a single hardware failure.

[0041] 2. Possesses independent detection and full coverage capabilities for various types of faults. The design outside the CPU minimum system can be detected in real time by software. The status of the CPU minimum system is detected by a dynamic energy storage module based on ordered input. Based on the physical characteristic that disorder leads to entropy increase, the fault of the dynamic energy storage module itself can directly trigger hot standby switching.

[0042] 3. It has better switching performance. The system detection cycle can be configured according to the on-site requirements, and the minimum cycle can be less than 1ms, which is more than 50 times better than the existing system.

[0043] 4. It can always ensure that only one control unit communicates with the interface and management terminal object, avoiding dual master and control disorder.

[0055] The high real-time hot standby management method and system for digital agriculture IoT terminals based on the entropy reduction principle described in this invention are not only applicable to the management and control of various continuous IoT terminal objects in digital agriculture, but also to the design of seamless switching hot standby systems for digital agriculture with high reliability requirements. Furthermore, the hot standby system based on entropy difference detection and energy storage management can be extended to other embedded application scenarios in digital agriculture.

[0056] A hot standby management method for digital agricultural IoT terminals based on the principle of entropy reduction is implemented using a hot standby management system for digital agricultural IoT terminals based on the principle of entropy reduction. Please refer to [link / reference]. Figure 1 As shown, it may include the following steps:

[0057] S110. Receive life signals sent by the first control unit and the second control unit. When both life signals are valid, select one of the first control unit and the second control unit as the host and connect its control module's corresponding interface to the interface of the agricultural IoT continuous terminal object. The other of the first control unit and the second control unit serves as the backup unit.

[0058] A digital agriculture IoT terminal hot standby management system based on the entropy reduction principle is available for reference. Figure 2 As shown, it may include a first control unit, a second control unit, a switching strategy module 220, and an agricultural IoT continuous terminal object 210. The selection of either the first or second control unit as the master unit allows the user to determine the master / standby initialization strategy. This can be designed for manual selection of the power-on master unit, or for the CPU to autonomously determine the master / standby unit by reading configuration signals through external hardware configuration. Typically, this can be configured using 2 bits, with 01 representing machine A and 10 representing machine B. Upon power-on, machine A is the default master unit, and machine B is the standby unit.

[0059] Taking the initial configuration of the first control unit as the host and the initial configuration of the second control unit as the standby unit as an example, the first control unit may include the A unit control module 231 and the A unit energy storage module 232, and the second control unit may include the B unit control module 241 and the B unit energy storage module 242.

[0060] Please refer to Figure 3 As shown, after the system initialization is successful, the identification signals of the first control unit and the second control unit are read (for example, the configuration signal is read as the identification signal by the CPU of the A-machine control module 231 and the B-machine control module 241). When the A-machine is identified, it is set as the master machine; otherwise, it is set as the standby machine. After that, whether it is the master machine or the standby machine, it will periodically generate an ordered excitation signal to enable the life signal through its energy storage module. The switching decision module identifies the two life signals output by the A-machine and the B-machine. After the system initialization is completed, if the life signals of the A-machine and the B-machine are both valid, the A-machine is selected as the master machine and its interface is connected to the terminal object. At this time, the B-machine is the standby machine and is not connected to the terminal object.

[0061] The switching strategy module 220 receives life signals sent by the first control unit and the second control unit. When both life signals are valid, the first control unit is selected as the host. The corresponding interface of the A-machine control module 231 is connected to the interface of the agricultural IoT continuous terminal object through the electronic selection switch to realize communication between the two. The interface function is determined according to the type of the digital agricultural IoT continuous terminal object. The interface can be any one or more of signal acquisition, signal processing, signal transmission (communication) and drive control. The other second control unit is used as a backup. At this time, the second control unit is not connected to the agricultural IoT continuous terminal object.

[0062] The interfaces of machine A control module 231 and machine B control module 241 with the agricultural IoT continuous terminal object 210 are selected and output through the switching decision module. After the entire system powers on and performs a normal self-test, machine A control module 231 and machine B control module 241 output ordered excitation signals. The corresponding energy storage modules receive the ordered excitation signals, thereby triggering the entropy reduction mechanism. The energy storage modules maintain energy storage and output life signals; when the life signals are valid, they synchronously output valid feedback signals to the corresponding control modules. According to the usual strategy, when the life signals of machine A control module 231 and machine B control module 241 are both valid, the switching decision module connects the input / output interface of machine A control module 231 to the terminal object, and machine B control module 241 becomes a backup. This ensures that there is no dual-master control situation from power-on to normal operation.

[0063] It is understandable that the electronic selection switch of the switching strategy module 220 can be a two-to-one electronic switch, such as a data selector, which determines the selection object based on the life signal, or it can be controlled by two analog switches, such as MOSFETs, where the life signal received by the switching strategy module 220 drives the MOSFETs to turn on or off to control the connection between the control unit and the agricultural IoT continuous terminal object 210.

[0064] When the A-machine control module 231 detects an anomaly or a software malfunction, and is unable to maintain an ordered excitation signal, the A-machine energy storage module 232, without an ordered excitation signal input, stops its entropy reduction mechanism from guiding entropy increase, releases energy, and thus stops the life-saving signal. After the life-saving signal stops, the switching decision module not only cuts off the output of the local unit but also immediately promotes the standby unit to take over as the primary unit, thereby achieving high real-time continuous management and control. This ensures that there will be no dual-master control during normal operation and switching.

[0065] Taking the first control unit (Unit A) as an example, the process of the second control unit acquiring the life signal is similar. Its Unit A control module 231 generates an ordered excitation signal, which is then used by the Unit A energy storage module 232 to generate the life signal. After the Unit A control module 231 passes its power-on self-test, it outputs the ordered excitation signal. This ordered excitation signal characterizes the effectiveness of the control module and maintains the entropy reduction mechanism of the energy storage module. The ordered excitation signal is dynamically generated by the control module software according to stringent timing requirements.

[0066] Specifically, please refer to Figure 4 As shown, the ordered excitation signal consists of a baseband signal composed of combinations of 0s and 1s. The time of each bit is a preset time, and the period of the baseband signal is managed by generating a preset time interrupt through the built-in timer 2311. The interrupt service module 2312 processes the timer interrupt and generates a dynamic baseband code every cycle. This dynamic code is a square wave signal with alternating 0s and 1s.

[0067] Based on the characteristics of continuous terminal objects in digital agriculture IoT, determine their seamless switching performance requirements, such as less than 5ms or less than 2ms. Correspondingly, determine the frequency value of the ordered excitation signal and the detection period of the timing monitoring module. For example, the preset period can be set to 1ms, then the frequency value of the ordered excitation signal is 500Hz, and the detection period of the timing monitoring module is also set to 1ms.

[0068] Whether the dynamic baseband code can be output depends on whether the enable signal of the timing monitoring module 2313 is valid. The timing monitoring module 2313 manages whether the software is running normally according to the set timing by period counting and clearing. When the software is normal, enable 2314 is turned on; when the software is abnormal, enable 2314 is turned off. When enabled, the dynamic baseband code is output as an ordered excitation signal.

[0069] The ordered excitation signal is determined by the operating state of the corresponding control module. If the control module A malfunctions, it must be able to detect and stop the output of the ordered excitation signal in a timely manner, so that the control module B can take over, thus ensuring the safe application of the terminal object. The malfunctions of the control module corresponding to this invention can be divided into two main categories: malfunctions detectable by the CPU software and malfunctions caused by the CPU software itself.

[0070] During CPU power-on and normal operation, a comprehensive hardware self-test is performed, including external interfaces, internal expansion circuits, the CPU minimum system circuitry, and other expansion circuits. If the host power-on self-test fails, the ordered excitation signal remains invalid, preventing the energy storage module from outputting a lifeline signal, and the system is switched from standby to host. If the host detects a fault during normal operation, it will also proactively stop the ordered excitation signal, and the system will switch from standby to host.

[0071] However, if the CPU software malfunctions due to its own bugs or external interference, the software itself no longer has the ability to detect the problem, and the software timing cannot be guaranteed. At this time, the timing monitoring module detects the abnormality and disables the output enable of the ordered stimulus signal.

[0072] Please refer to Figure 5 As shown, the energy storage module 232 of machine A includes an entropy difference detection module 2321, an inverter module 2322, an energy pool 2323, and a load 2325; the entropy difference detection module receives the ordered excitation signal and detects the ordered excitation signal; if the ordered excitation signal is valid, the entropy difference detection module 2321 can detect an entropy decrease; if the ordered excitation signal is invalid, the entropy difference detection module 2321 can detect an entropy increase. When an entropy decrease signal is detected, an AC signal is generated using the entropy decrease signal as the input signal for the inverter module 2322. Combined with the drive source, the AC signal can be inverted into a higher voltage DC voltage source to charge the energy pool 2323. In addition, the front-end entropy difference detection module 2321 will synchronously output the entropy increase or decrease criterion, which is converted into an enable signal 2326 to control the storage or release of energy in the energy pool. For example, the entropy decrease signal enables the control switch 2324 between the energy pool 2323 and the load 2325 to close, and the energy pool 2323 outputs a life signal through the load. When an entropy increase signal is detected, the control switch 2324 between the energy pool 2323 and the load 2325 is enabled, and the A-machine energy storage module 232 does not output a life signal.

[0073] Since the life signal is generated by a load connected to the energy pool, it only takes 1ms for the life signal to change from valid to invalid, or from invalid to valid, thus ensuring an extremely fast system response.

[0074] S120. Real-time detection of life signals emitted by the host and the backup unit. When the life signal emitted by the host is invalid and the life signal emitted by the backup unit is valid, the backup unit is used as the new host, and the corresponding interface of the control module of the new host is connected to the interface of the agricultural Internet of Things continuous terminal object.

[0075] During normal operation, the switching decision module monitors the validity of the two life signals in real time. If a life signal changes from valid to invalid, a falling edge (high to low) is generated, which triggers the electronic selection switch inside the switching decision module. The response time of the electronic selection switch is in the nanosecond range, which is negligible in system applications.

[0076] Please refer to Figure 6As shown, the switching decision module monitors the validity of the two life signals in real time. If both life signals are valid, the initial control strategy remains unchanged. When the life signal from the host changes from valid to invalid and the life signal generated by the standby unit is valid, the switching decision module switches the interface of the original host to the interface of the original standby unit through an electronic selection switch. The original standby unit becomes the new host, and the original host is restarted. After restarting, it enters the new standby unit state. At this time, the entire system has the function of hot standby redundancy of two systems.

[0077] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0078] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the embodiments of the present invention shall fall within the scope of protection claimed by the present invention.

The digital agriculture IoT terminal hot standby management system based on the entropy reduction principle as described in claim 6, characterized in that, The energy storage module includes an entropy difference detection module, an inverter module, an energy pool, and a load; the ordered excitation signal is converted into a life signal based on entropy difference detection through the corresponding energy storage module, including: The entropy difference detection module receives the ordered excitation signal and detects the ordered excitation signal; When an entropy reduction signal is detected, the ordered excitation signal is valid. The entropy reduction signal is then used to generate an AC signal, which is used as the input signal of the inverter module. The AC signal is then converted into a DC voltage signal by the drive source to charge the energy pool. The entropy reduction signal also enables the control switch between the energy pool and the load to close, and the energy pool outputs a life signal through the load. When the entropy increase signal is detected, the ordered excitation signal becomes invalid, and the control switch between the energy pool and the load is disconnected, so the energy storage module does not output a life signal.
