At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0040] It should be noted that IoT devices, i.e. IoT (Internet of Things, IoT) devices, refer to physical devices that can connect and communicate through the Internet. The business management layer of IoT devices refers to the business management abstraction layer used to process data interaction between the business threads of IoT devices and servers. In practical applications, the business threads of IoT devices can run in the business management layer. The network management layer of IoT devices, i.e. the network connection management layer of IoT devices, refers to the network management abstraction layer used to manage the network connection status of IoT devices. In practical applications, the network management thread of IoT devices can run in the network management layer. The specific manifestation of the network connection management layer of IoT devices can be a 4G physical module in IoT devices (i.e. the 4G physical layer in IoT devices), based on which, the wireless communication network between IoT devices and servers can be a 4G network.

[0041] In one embodiment, Figure 1 As shown, a service state control method is provided, which is applied to the service management layer of an IoT device, and includes the following steps:

[0042] Step S110, in response to the service wake-up signal, start data transmission with the server; the aforementioned service wake-up signal is output by the network management layer of the IoT device when a connection with the server has been established and the device has entered an idle state.

[0043] Among them, the service wake-up signal refers to the service wake-up signal output by the network management layer of the Internet of Things device to the service management layer of the Internet of Things device when the connection with the server has been established and the device has entered an idle state.

[0044] In actual applications, the server that transmits data with the business management layer may be a cloud server; the business thread in the business management layer of the IoT device, after starting data transmission between the device and the server in response to a business wake-up signal, may continue to run in a loop in the data transmission state (which belongs to the normal working state of the business thread in the business management layer) until an abnormality occurs in the data transmission state between the device and the server.

[0045] Furthermore, receiving a service wake-up signal from the network management layer can be used as a starting event of a state machine of the service management layer of the IoT device.

[0046] Step S120: based on the data transmission status with the server, confirm whether it is necessary to start the exception handling process.

[0047] Among them, the data transmission status between the server refers to the data transmission status between the business management layer of the IoT device and the server; the exception handling process refers to the business management layer of the IoT device, which determines whether to start the exception handling process based on the data transmission status between the device and the server.

[0048] The above-mentioned business status control method, device, equipment and storage medium highly abstract the running process of the business thread and the network management thread in the Internet of Things device into the business management layer and the network management layer, and between the business management layer and the network management layer, by making the network management layer output a business wake-up signal to the business management layer when the network connection is successful and has entered the idle state, notifying the business management layer to start data transmission between the server, and making the business management layer confirm whether it is necessary to start the exception handling process based on the data transmission status between the server, which can not only reduce the meaningless power consumption of the Internet of Things device, but also effectively improve the operating stability of the Internet of Things device.

[0049] Regarding the specific method of starting the exception handling process, in one embodiment, as Figure 2 As shown, the above step S120 specifically includes the following steps:

[0050] Step S210, when data transmission with the server fails, start the exception handling process.

[0051] Among them, the data transmission failure between the server refers to the data transmission failure between the business management layer of the IoT device and the server; the exception handling process refers to the exception handling process initiated by the business management layer of the IoT device when the data transmission between the server fails.

[0052] In actual applications, the failure of data transmission between the business management layer of the IoT device and the server can be specifically manifested as a communication failure between the business thread in the business management layer of the IoT device and the server, a business interaction failure (for example, a heartbeat business interaction failure), etc.; the failure of data transmission between the business management layer of the IoT device and the server can be used to indicate that there may be a problem with the communication network between the business thread in the business management layer of the IoT device and the server (that is, the underlying network resources between the business management layer of the IoT device and the server).

[0053] Step S220, outputting an exception processing signal and restoring to the first initial state; the aforementioned exception processing signal is used to instruct the network management layer to restore to the second initial state.

[0054] Among them, the exception handling signal refers to the exception handling signal output by the business management layer of the Internet of Things device to the network management layer of the Internet of Things device after the exception handling process is started. The exception handling signal can be used to notify the network management layer of the Internet of Things device to check the network connection status of the Internet of Things device from the beginning; the first initial state, that is, the first initial state of the business management layer of the Internet of Things device; the second initial state, that is, the second initial state of the network management layer of the Internet of Things device.

[0055] In actual applications, the business management layer of the Internet of Things device is restored to the first initial state in the form of suspending the business threads in the business management layer and entering a cyclic sleep state (suspending the business threads can give up CPU resources, thereby reducing meaningless power consumption of the Internet of Things device), and waking up from the sleep state based on a preset interval to confirm whether the business wake-up signal output by the network management layer of the Internet of Things device has been received.

[0056] Furthermore, outputting an exception handling signal to the network management layer can serve as an endpoint event of the state machine of the business management layer of the IoT device.

[0057] The embodiment of the present application enables the business management layer to start the exception handling process when data transmission between the business management layer and the server fails, outputs an exception handling signal to the network management layer, and restores to the first initial state, thereby effectively reducing the meaningless power consumption of the Internet of Things device and ensuring the stable operation of the Internet of Things device.

[0058] Regarding the specific manner of confirming whether the service wake-up signal has been received, in one embodiment, the method further includes the following steps:

[0059] Step S310: In a first initial state, based on a preset interval duration, confirm whether a service wake-up signal has been received.

[0060] Among them, the first initial state is the first initial state of the business management layer of the Internet of Things device; the preset interval duration refers to waking up the business thread in the business management layer of the Internet of Things device from the sleep state to confirm whether a business wake-up signal has been received for a preset interval duration; the business wake-up signal refers to the business wake-up signal output by the network management layer of the Internet of Things device to the business management layer of the Internet of Things device when the connection with the server has been established and the device has entered an idle state.

[0061] Specifically, if Figure 3 As shown, the above step S310 may be performed before the above step S110.

[0062] The embodiment of the present application effectively reduces the meaningless power consumption of the Internet of Things device by allowing the service management layer to confirm whether a service wake-up signal has been received based on a preset interval duration in a first initial state.

[0063] In one embodiment, Figure 4 As shown, a service state control method is provided, which is applied to the network management layer of the Internet of Things device, including the following steps:

[0064] Step S410, after the connection with the server has been established, enter the idle state and output a service wake-up signal; the aforementioned service wake-up signal is used to instruct the service management layer of the Internet of Things device to start data transmission with the server.

[0065] Among them, the service wake-up signal refers to the service wake-up signal output by the network management layer of the IoT device to the service management layer of the IoT device when the connection with the server has been established and the device has entered an idle state. The service wake-up signal can be used to notify the service management layer of the IoT device that the network resources are now ready and to instruct the service management layer to start data transmission with the server.

[0066] In actual applications, the server can be a cloud server; when the network management layer of the IoT device has established a connection with the server and has entered an idle state, the network management thread in the network management layer will temporarily enter a cyclic sleep state (the suspended network management thread can give up CPU resources, thereby reducing meaningless power consumption of the IoT device), and wake up from the sleep state regularly to confirm that the business thread in the business management layer has started the exception handling process.

[0067] Furthermore, after the connection with the server is established, the idle state is entered, and a service wake-up signal is output to the service management layer, which can be used as the end event of the state machine of the network management layer.

[0068] Step S420, when confirming that the business management layer has started the exception handling process, restore to the second initial state.

[0069] The second initial state refers to the second initial state entered by the network management layer of the Internet of Things device when it is confirmed that the business management layer of the Internet of Things device has started the exception handling process.

[0070] In actual applications, after the network management layer of the Internet of Things device is restored to the second initial state, the network connection status of the Internet of Things device can be checked from the beginning; the specific form of the network management layer of the Internet of Things device being restored to the second initial state can be that the network management thread in the network management layer of the Internet of Things device enters the hardware initialization state.

[0071] Furthermore, entering the hardware initialization state can serve as a starting event for the state machine of the network management layer.

[0072] The above-mentioned business status control method, device, equipment and storage medium highly abstract the running process of the business thread and the network management thread in the Internet of Things device into the business management layer and the network management layer, and between the business management layer and the network management layer, by making the network management layer output a business wake-up signal to the business management layer when the network connection is successful and has entered the idle state, notifying the business management layer to start data transmission between the server, and making the network management layer restore to the second initial state when confirming that the business management layer has started the exception handling process. This can not only reduce the meaningless power consumption of the Internet of Things device, but also effectively improve the operating stability of the Internet of Things device.

[0073] Regarding the specific method of restoring to the second initial state, in one embodiment, the above step S420 specifically includes:

[0074] In response to an exception handling signal, the system returns to the second initial state; the exception handling signal is output by the business management layer when data transmission between the business management layer and the server fails.

[0075] Among them, the exception handling signal refers to the exception handling signal output by the business management layer of the Internet of Things device to the network management layer of the Internet of Things device when the data transmission between the business management layer of the Internet of Things device and the server fails. The exception handling signal can be used to indicate that the data transmission between the business management layer of the Internet of Things device and the server has failed, and the exception handling process has been initiated.

[0076] The embodiment of the present application effectively reduces the meaningless power consumption of the Internet of Things devices by causing the network management layer to recover to the second initial state in response to the exception processing signal output by the business management layer and check the network connection status of the Internet of Things device from the beginning.

[0077] Regarding the specific manner of establishing a connection with the server, in one embodiment, the second initial state is a hardware initialization state; and the method further includes:

[0078] Step S510: When the SIM card is in place and the network is successfully accessed, a connection with the server is established.

[0079] Among them, SIM card in place means that the SIM card of the IoT device has been correctly installed; successful network installation means that the IoT device has completed network installation.

[0080] Specifically, if Figure 5As shown, the above step S510 can be executed before the above step S410; in addition, before executing the above step S510, the network management thread in the network management layer can first enter the dial-up initialization state.

[0081] In actual applications, when it is detected that the SIM card of the IoT device is not in place, the presence status of the SIM card of the IoT device can be detected again after restarting the IoT device; when it is detected that the IoT device fails to log on to the network, the network can be retried by turning on the flight mode, restarting the IoT device, etc.; the network management layer of the IoT device can establish a connection with the server in a specific way, which can be a dial-up connection (that is, the network management thread in the network management layer of the IoT device can establish a network connection with the server if the dial-up is successful); if the network management thread fails to successfully establish a connection with the server, an attempt can be made to establish a connection between the network management thread and the server by retrying the connection multiple times, starting the ping program to detect whether the network is connected, and rechecking the network status of the IoT device.

[0082] The embodiment of the present application effectively ensures the operational stability of the Internet of Things device by enabling the network management layer to establish a connection with the server when the SIM card is in place and the network is successfully established.

[0083] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
