Background

In order to ensure real-time remote transmission of video data streams, single or multiple video monitoring devices in the same area need to be in operation for a long period of time.

Video monitoring devices are generally powered by a battery, but the power of the battery is limited, and the power consumption of devices with high-speed transmission capability in the video monitoring devices is high, so that if long-term operation of the devices is to be maintained, the working time of the video monitoring devices is shortened.

Disclosure of Invention

The application provides an information transmission method, an information transmission device and electronic equipment, which are used for reducing power consumed by high-speed transmission of remote information by multiple nodes.

In a first aspect, the present application provides a method for information transmission, the method comprising:

the method comprises the steps that a first type node receives a transmission request for requesting the node to transmit remote information and judges whether a node identifier in the transmission request is matched with a preset identifier; wherein, the single node comprises a high-power-consumption device in a dormant state and a low-power-consumption device in the dormant state;

if yes, switching the high-power-consumption devices of the first type of nodes into an enabling state, and transmitting information through the high-power-consumption devices of the first type of nodes;

if not, switching the low-power-consumption device of the first type node into an enabling state, and forwarding the transmission request to the second type node through the low-power-consumption device of the first type node.

In summary, if the request object of the transmission request is the first type node, only the high power consumption device of the first type node will be switched to the enabled state, and the high power consumption node of the second type node will not be enabled, so that the power consumption of the multi-node remote information transmission is reduced.

If the request object of the transmission request is the second type node, the high power consumption node of the first type node is not started, so that the power consumption of the multi-node remote information transmission is reduced.

In one possible design, the high power devices of the first type node are in a first sleep state, and the low power devices of the first type node are in a second sleep state;

the high-power-consumption devices of the second class of nodes are in a second dormant state, and the low-power-consumption devices of the second class of nodes are in a first dormant state;

wherein the same device consumes higher power in the first sleep state than in the second sleep state.

In some possible embodiments, the device may be in a first sleep state for periodic heartbeat keep-alive, and the device may be in a second sleep state for power-down processing, i.e., the same device may be in the first sleep state with greater power consumption than the same device is in the second sleep state.

In summary, the first type node can keep alive with the remote platform or device through heartbeat by the high power device in the low power mode, so as to ensure that the remote platform or device can acquire the requested data information at any time.

The second type node can keep alive with the first type node through the low power consumption equipment periodically under the low power consumption mode so as to acquire the transmission request forwarded by the first type node, further ensure that a remote platform or equipment can acquire the requested data information at any time after sending the transmission request, and in addition, the second type node also performs power-off processing on the high power consumption equipment so as to achieve the purpose of saving power consumption.

In summary, the number of the response messages may represent the number of the nodes covered by the first type node, that is, the purpose of receiving the response messages is to determine whether to complete the coverage of all the second type nodes currently, and the low-power devices may cover different numbers of nodes under different power consumption, so that the power consumed by the low-power devices in the process of receiving the response messages can be effectively reduced by adopting the power consumption of the low-power devices from low to high to transmit power.

In one possible design, the determining that the number of received response messages and the power consumption corresponding to the low-power consumption device all meet the preset conditions includes:

the first type node receives response messages sent by each node in the appointed area through the low-power consumption device;

if the power consumption corresponding to the low-power consumption device of the first type node is smaller than the power consumption corresponding to the low-power consumption device of the competing node, determining that a preset condition is met; the competing nodes are second class nodes which receive response messages sent by each node in the appointed area.

In summary, the first class node of the low-power device, which covers all nodes in the designated area with the lowest power consumption, can be selected, and optionally, other nodes are used as the second class node, and the first class node proxies all the second class nodes to achieve the effect of reducing the power consumption of remote information transmission.

As shown in fig. 2, the node structure may include: the system comprises an acquisition module, a high-power-consumption module, a low-power-consumption module and a main processor module.

The acquisition module is used for acquiring image information or video information and storing the acquired information, such as storing the acquired video information as video data. The acquisition module may include a camera and a sensor, where the camera includes a fisheye camera, an infrared camera, a security camera, and the like, and the sensor includes a CCD (Charge-Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor ), and the like. In addition, the acquisition module can acquire other information, such as temperature information, humidity information and the like, based on actual application requirements.

The high-power consumption module is used for transmitting information at a high speed, and can be a cellular module, in particular to remotely transmit the image information or the video information acquired by the acquisition module or to receive a transmission request for requesting to remotely transmit the information. The high power consumption module includes high power consumption devices such as: wi-Fi (Wireless Fidelity, wireless communication Technology) devices, 4G (4G Technology, fourth generation mobile communication and Technology thereof) devices, 5G (5G Technology, fifth generation mobile communication and Technology thereof) devices, and the like.

The low power consumption module is used to broadcast information and the power consumed by the low power consumption broadcast module to operate should be lower than the power consumed by the high power consumption module to operate. The low power module includes low power devices such as: BLE (Bluetooth Low Energy ) devices, zigBee (ZigBee protocol) devices, and the like.

Optionally, the low-power consumption module may be further divided into a low-power consumption control module and a low-power consumption broadcast module, where the low-power consumption control module is configured to control the low-power consumption broadcast module to implement a heartbeat keep-alive function when in a low-power consumption mode. The low-power consumption broadcasting module is used for broadcasting information, and comprises low-power consumption devices, and the low-power consumption broadcasting module can comprise a BLE module, a ZigBee module and the like.

The main processor module is used for realizing the processing of the comprehensive business.

After the node structure is introduced, the operation modes of the node are briefly described as follows in combination with the node structure, and the operation modes of the node can be divided into a normal mode and a low power consumption mode.

And in the normal mode, the working flows of the first type of nodes and the second type of nodes are the same, namely the nodes are electrified for each module, and the acquisition module, the high-power-consumption module, the low-power-consumption control module, the low-power-consumption broadcast module and the main processor module are all switched into an enabling state. As shown in fig. 3a, the structure of the first type node in the normal mode is shown; as shown in fig. 3b, the structure of the second class node in the normal mode is shown.

The workflow of the first class node and the second class node in the low power mode is different.

A first type of node: the first type of node in the low power consumption mode is used for powering up the acquisition module, the high power consumption module and the low power consumption control module, and powering down the low power consumption broadcasting module and the main processor module.

As shown in fig. 4a, the first type of node is in a low power mode: switching the acquisition module and the low-power consumption control module into an enabling state; switching a high-power-consumption device in the high-power-consumption module to a first dormant state; and switching the low-power-consumption devices and the main processor module in the low-power-consumption broadcasting module into a second dormant state.

The second class of nodes: the second type of node in the low power consumption mode is used for powering up the acquisition module, the low power consumption control module and the low power consumption broadcasting module, and powering down the high power consumption module and the main processor module.

As shown in fig. 4b, the second class of nodes is in a low power mode: switching the acquisition module and the low-power consumption control module into an enabling state; switching low-power-consumption devices in the low-power-consumption broadcasting module to a first dormant state; and switching the high-power consumption module and the main processor module into a second dormant state.

The device is in a first sleep state and can keep alive in regular heartbeat, and the device is in a second sleep state and can perform power-off processing, namely the power consumption of the same device in the first sleep state is larger than that of the same device in the second sleep state. The heartbeat keep-alive adopts a heartbeat mechanism, which is a mechanism for periodically sending a self-defined structure body (heartbeat package) to enable the opposite party to know that the opposite party is still alive so as to ensure the validity of connection.

The different workflow of the first class node and the second class node in the low power consumption mode can be known: the first type node can regularly keep alive through heartbeat between the high-power-consumption device and a remote platform or equipment in a low-power-consumption mode so as to ensure that the remote platform or equipment can acquire pull stream data at any time, wherein the pull stream data is image information or video information acquired by a node acquisition module, and in addition, the first type node also performs power-off treatment on the low-power-consumption device so as to achieve the purpose of saving power consumption; the second type node can regularly keep alive with the first type node through the low-power-consumption device under the low-power-consumption mode so as to acquire a transmission request forwarded by the first type node, further ensure that a remote platform or equipment can acquire pull stream data at any time after sending the transmission request, and in addition, the second type node also performs power-off processing on the high-power-consumption equipment so as to achieve the purpose of saving power consumption.

In order to ensure reliability of the multi-node in the process of remote information transmission, the embodiment of the application further provides a node classification method, which is used for classifying a plurality of nodes in a designated area, as shown in fig. 5, any node is taken as an execution body, and hereinafter, any node is collectively called as a node, and the specific flow is as follows:

step 501: the node sets the transmitting power of the low-power-consumption device to be the maximum, and transmits broadcast information to other nodes through the low-power-consumption device;

firstly, starting a node, initializing a low-power-consumption broadcasting module of the node, starting a low-power-consumption device in the low-power-consumption broadcasting module, setting the low-power-consumption device as the maximum transmitting power, and sending broadcasting information for requesting to acquire node information to nearby nodes through the low-power-consumption device.

Further, if the node receives the broadcast information sent by other nodes, the node forwards the received broadcast information to ensure that each node in the designated area can receive the broadcast information sent by each other, and further obtain the node information of each node in the designated area.

Optionally, the node receives the statistics of the node information of other nodes, and broadcasts the counted node information so that other nodes count corresponding information. Until the time spent in this operation meets the preset statistical time, then step 502 will be performed; if however the time spent in this operation does not meet the preset statistical time, then step 501 will continue.

Step 502: after the broadcast information is sent, traversing each transmitting power of the low-power-consumption device from low to high, and determining whether response messages of all other nodes are received within preset waiting time;

sequentially sending detection messages to other nodes from the lowest transmitting power of the low-power-consumption device; if the other node receives the detection message, the other node replies a response message, wherein the response message is used for representing: "I can receive messages you send", based on this, a correspondence between the transmit power of the low power device and the number of received response messages can be established.

For example, the low power device of the node has a transmit power of m ₁ After sending the detection message to other nodes through the low-power-consumption device, receiving k ₁ Response messages replied by individual nodes, i.e. the number of response messages is k ₁ The method comprises the steps of carrying out a first treatment on the surface of the The low-power consumption device of the node has the transmission power of m ₂ After sending the detection message to other nodes through the low-power-consumption device, receiving k ₂ Response messages replied by individual nodes, i.e. the number of response messages is k ₂ The method comprises the steps of carrying out a first treatment on the surface of the By analogy, the corresponding relation between the transmitting power of the low-power-consumption device and the number of the received response messages can be obtained, wherein m ₁ <m ₂ ，k ₁ ≤k ₂ The details are shown in table 1 below:

TABLE 1

For the nodes, the node information is counted in step 501, that is, the node information of each node in the designated area can be obtained, that is, the node can obtain the total number of the nodes in the designated area. Assuming that the total number of nodes in the designated area is n, based on the correspondence shown in table 1, the transmission power of the corresponding low power device can be determined by comparing whether the number of received response messages is equal to the number of nodes in the designated area. For example, k ₁ The transmitting power of the corresponding low-power consumption device is m ₁ If k ₁ <n, the low power consumption device of the node adopts m ₁ Not covering all nodes in the designated area, it is necessary to increase the transmission power of the low power device to m ₂ ；k ₂ The transmitting power of the corresponding low-power consumption device is m ₂ If k ₂ N, then the low power device of the node adopts m ₂ And the transmission power of the low-power device can be covered on all nodes in the designated area, so that the transmission power of the low-power device does not need to be increased.

In summary, it is determined whether response messages of all other nodes are received within a preset waiting time: if yes, the node determines the transmit power of the corresponding low power device, and executes step 503; if not, go to step 507.

Step 503: after determining that response messages of all other nodes are received within preset waiting time, generating a competition message, and broadcasting the competition message through a low-power-consumption device;

the contention message contains the transmitting power of the corresponding low-power-consumption device, and the purpose of broadcasting the contention message to other nodes in the designated area is to tell the other nodes: "I can realize the full coverage of other nodes in the designated area by how much transmit power of the low-power-consumption device".

It is easy to understand that the node also receives the contention message sent by other contention nodes, and the contention node is a node that receives the response message sent by all other nodes in the designated area.

Step 504: judging whether the transmitting power in the competition message is smaller than the transmitting power in the competition message of other competition nodes;

if yes, go to step 505; if not, go to step 506.

Step 505: determining the first type node;

the transmission power in the contention message is smaller than that in the contention messages of other contention nodes, which indicates that the node can cover all nodes in the designated area with smaller transmission power, so that it is determined that the node contention is successful as a first type node, the first type node is used for acting on all nodes in the designated area, and other nodes with failed contention are second type nodes, and after the first type node is determined, the first type node sends a broadcast notification to the second type node.

In one possible design, the first number in the referral message is less than the second number in the referral messages of each of the other nodes, indicating that the node may cover the most nodes in the designated area, thereby determining that the node contention is successful as a first type node, the first type node being used to proxy all nodes in the designated area, and the other nodes failing to contend as a second type node, after determining the first type node, the first type node will send a broadcast notification to the second type node.

Step 506: judging whether competition messages sent by other nodes are received within a certain time;

in one possible design, although each node in the designated area uses the maximum transmit power of the low power devices, none of the nodes may receive the response messages sent by all of the nodes in the designated area. Here, whether or not the above situation occurs is discriminated by determining whether or not a contention message transmitted by another node is received within a certain time.

If the competition message sent by the other node is received within a certain time, step 509 is executed; if no contention message sent by other nodes is received within a certain time, step 507 is executed.

Step 507: determining the maximum transmitting power of a low-power-consumption device, generating a first number of received response messages, generating a self-recommendation message carrying the first number, and transmitting the self-recommendation message;

the method comprises the steps that the self-recommendation message is broadcast to other nodes in a designated area with the maximum transmitting power of a low-power device according to the first quantity of received response messages, and the purpose of the self-recommendation message is to tell the other nodes: "I can cover the number of nodes in the specified area as the first number".

It is easy to understand that the node also receives the self-recommendation messages sent by other nodes in the designated area, and the self-recommendation messages sent by other nodes respectively contain a second number, and the second number indicates the number of response messages received by any other node.

Step 508: judging whether the first quantity in the self-recommendation message is larger than the second quantity in the self-recommendation message of each other node;

if yes, go to step 505; if not, step 509 is performed.

Step 509: determining the node as a class II node;

the transmission power in the contention message is greater than or equal to the transmission power in the contention message of other contention nodes, indicating that the node cannot cover all nodes in the designated area with smaller transmission power, which is described in the following two cases.

In the first case, the transmission power in the contention message is greater than the transmission power in the contention message of other contention nodes, which indicates that the node cannot cover all nodes in the designated area with smaller transmission power, or that other nodes in the designated area can cover all nodes in the designated area with smaller transmission power, so that it is determined that the node contention failure is a second class node, and the second class node sends its own node information to the first class node proxy by receiving the broadcast notification sent by the first class node.

And secondly, if the transmission power in the contention message is equal to the transmission power in the contention messages of other contention nodes, the fact that at least two nodes in the designated area can cover all nodes in the designated area with the same transmission power is indicated, and the contention message without other nodes contains smaller transmission power, then one node is selected from the nodes with the same transmission power as a first type node with successful contention, the other nodes as a second type node with failed node contention, and the second type node sends own node information to the first type node agent by receiving broadcast notification sent by the first type node.

In one possible design, the first number in the referral message is less than or equal to the second number in the referral message of each of the other nodes, indicating that the node cannot cover the most nodes in the designated area, as described in the following two cases.

In the first case, the first number in the self-recommendation message is smaller than the second number in the self-recommendation message of each other node, which indicates that the node cannot cover the most nodes in the designated area, or other nodes in the designated area can cover more nodes in the designated area, so that the node competition failure is determined to be the second type node, and the second type node sends own node information to the first type node agent by receiving the broadcast notification sent by the first type node.

And in the second case, the first number in the self-recommendation message is equal to the second number in the self-recommendation message of each other node, which indicates that at least two nodes in the designated area can cover the same number of nodes in the designated area, and no other nodes cover more nodes in the designated area, then one node is selected from the nodes which cover the same number of nodes as a first type node with successful competition, the other nodes as a second type node with failed competition of the nodes, and the second type node sends own node information to the first type node agent by receiving broadcast notification sent by the first type node.

Through the steps, firstly, each node in a designated area is determined, and then, each node class can be determined according to the node classification method for each node, so that a first class node and a second class node are obtained.

The node classification method can screen out the first class nodes of which the low-power devices fully cover all the nodes in the designated area with the lowest power consumption, take other nodes as the second class nodes, and proxy all the second class nodes by the first class nodes so as to achieve the purpose of reducing the power consumption of remote information transmission.

If the first type node is not screened, the respective low-power devices of the nodes can be started based on the highest power consumption to cover the nodes in the designated area, and the most nodes in the designated area are selected to be used as the first type node. For example, there are 10 nodes in the designated area, each of the 10 nodes enables the highest power consumption low power consumption device, wherein node 1 covers 7 nodes in the designated area, and there are no 8 or more nodes in the designated area, then node 1 is considered as the first type of node. Optionally, for the remaining 2 nodes in the designated area that are not covered by the node 1, the same idea is adopted to screen out the first class nodes in the 2 nodes. In this way, the full coverage of the first class node to all the second class nodes in the designated area can be ensured, so that the reliability of remote information transmission is ensured.

Based on the first class node and the second class node obtained by division, the embodiment of the application provides an information transmission method, as shown in fig. 6, and the specific flow is as follows:

the method comprises the following steps: the first type node receives a transmission request for requesting the node to transmit remote information;

before executing step 601, the first class node will also enable the low power consumption device to receive the response message sent by the second class node according to the preset rule, and if it is determined that the number of received response messages and the power consumption corresponding to the low power consumption device meet the preset conditions, the low power consumption device is switched to the second sleep state in response to entering the low power consumption mode.

It should be noted that, the first type node and the second type node are both nodes in the designated area, and the above operation is described by taking the first type node as an execution body as an example: how to define the node category of the self through corresponding operation so as to adjust the workflow when entering the low power consumption mode.

In other words, the first type node cannot definitely enter the working flow when the low power consumption mode when receiving the response message according to the preset rule, and can definitely enter the working flow when the low power consumption mode only when the number of the received response messages and the power consumption corresponding to the low power consumption device are determined to meet the preset condition, and then the low power consumption device is switched to the second sleep state and the high power consumption device is switched to the first sleep state.

The preset rule may be a rule that the first type node is arranged in ascending order of power consumption of the low power consumption devices, and the low power consumption devices are started to receive the response message sent by the second type node.

The preset condition can be divided into two sub-conditions, the first sub-condition is that the number of response messages sent by different nodes is the largest, the second sub-condition is that the power consumption corresponding to the low-power-consumption device is the smallest on the basis of the first sub-condition, and the preset condition is described in the following two cases.

In the first case, the first type node receives the response message sent by each node in the designated area through the low power consumption device, and if the power consumption corresponding to the low power consumption device of the first type node is smaller than the power consumption corresponding to the low power consumption device of the competing node at this time, the first type node can be determined to meet the preset condition. The competing nodes are second class nodes which receive response messages sent by each node in the designated area.

And secondly, enabling the highest power consumption of the low-power-consumption devices by the first type of nodes, receiving response messages through the low-power-consumption devices with the highest power consumption, determining the first quantity of the received response messages, acquiring the second quantity of the response messages received by each second type of nodes through the low-power-consumption devices with the highest power consumption, comparing the first quantity with each second quantity, and determining that the preset condition is met if the first quantity is larger than each second quantity.

In addition, the core concept of the above operation is the same as a node classification method shown in fig. 5, and those skilled in the art will recognize that if the execution body is a second class node, the same concept may also be adopted, which is not specifically described herein.

After determining the workflow when entering the low power consumption mode, the first type node switches the high power consumption device into a first dormant state, switches the low power consumption device into a second dormant state, and then receives a transmission request sent by a remote platform or equipment through the high power consumption device and used for requesting the node to transmit remote information.

Similarly, after determining the workflow when entering the low power consumption mode, the second type node switches the high power consumption device to the second sleep state, switches the low power consumption device to the first sleep state, and then receives the transmission request forwarded by the first type node through the low power consumption device.

Step 602: judging whether the node identification in the transmission request is matched with a preset identification or not;

the node identification in the transmission request can indicate the request object of the transmission request, i.e. which node the transmission request is requesting for the remote information transmission. The preset identifier is a node identifier of the first type node which receives the transmission request.

The first type node judges whether the node identification in the transmission request is matched with the preset identification of the first type node: if the node identifier in the transmission request is matched with the preset identifier of the node identifier, executing step 603; if the node identifier in the transmission request does not match the preset identifier of the node identifier, step 604 is performed.

Step 603: switching the high-power-consumption devices of the first type of nodes into an enabling state, and transmitting information through the high-power-consumption devices of the first type of nodes;

the node identification in the transmission request is matched with the preset identification to indicate that: the request object of the transmission request is the first type node itself, i.e. the first type node itself is requested to perform the remote information transmission. In order to perform remote information transmission, the first type node switches a high-power-consumption device of the first type from a first sleep state to an enabled state, and then performs remote information transmission based on the enabled high-power-consumption device.

For the second class of nodes, the second sleep state of the high power device and the first sleep state of the low power device are maintained, i.e. the high power device is not enabled.

Step 604: and switching the low-power-consumption devices of the first type of nodes into an enabling state, and forwarding the transmission request to the second type of nodes through the low-power-consumption devices of the first type of nodes.

The unmatched node identification in the transmission request and the preset identification indicate that: the request object of this transmission request is not a node of the first type but a node of the second type. At this time, the first type node needs to forward the transmission request to the second type node, so the first type node will switch its own low power consumption device from the second sleep state to the enabled state, and then send the transmission request to the second type node through the enabled low power consumption device.

For the second class node, the low-power consumption device of the second class node is in the first dormant state, and can periodically accept the transmission request forwarded by the first class node. After receiving the transmission request forwarded by the first class node, the second class node further determines whether the node identifier in the transmission request is matched with the preset identifier of the second class node or not: if not, neglecting the received transmission request; if so, the remote information transmission is performed based on the received transmission request.

And the second type of node switches the high-power-consumption device of the second type of node from a second dormant state to an enabling state for remote information transmission, and then carries out remote information transmission based on the enabled high-power-consumption device.

In addition, after the first type node forwards the transmission request, the low-power-consumption device is switched from the starting state to the second dormant state, and then the high-power-consumption device is kept in the first dormant state.

In summary, if the request object of the transmission request is the second type node, only the high power consumption device of the second type node will be switched to the enabled state, the high power consumption node of the first type node will not be enabled, so as to reduce the power consumption of the multi-node remote information transmission, in addition, the low power consumption device of the second type node is not enabled, and the power consumption wasted in the remote information transmission process of the second type node is further reduced.

Further, a detailed description of a method for transmitting information provided in the embodiments of the present application is provided below in connection with a specific application scenario.

As shown in fig. 7, the method for transmitting information in a video monitoring scene uses any node as an execution body, and hereinafter, any node is referred to as a node, and the specific flow is as follows:

Step 701: the node enters a normal mode and is connected with the cloud platform through a high-power-consumption device;

the node powers up each module and switches the acquisition module, the high-power-consumption module, the low-power-consumption control module, the low-power-consumption broadcasting module and the main processor module into an enabling state so as to enter a normal mode. The node is then connected to the remote cloud platform through the high power device in the high power module and a login operation on the cloud platform is implemented.

Step 702: judging whether video information needs to be pushed to a cloud platform currently or not;

the video information is acquired through the acquisition module, and the video information is pushed to be sent to the cloud platform.

Judging whether video information needs to be pushed to a cloud platform currently or not: if yes, go to step 703; if not, go to step 704.

Step 703: pushing the currently acquired video information to a cloud platform;

in the embodiment of the application, a period of time can be preset, that is, the video information collected in the preset period of time is pushed to the cloud platform, or the video information collected in the current period of time is pushed to the cloud platform.

Step 704: judging whether the node is a first type node or not;

the method of determination can be referred to as a node classification method. The first type node is used for receiving a transmission request sent by the cloud platform; the second class node is used for receiving the transmission request forwarded by the first class node.

Judging whether the node is a first type node: if not, go to step 705; if yes, step 707 is performed.

Step 705: switching the high-power-consumption device to a second sleep state, and switching the low-power-consumption device to a first sleep state;

if the node is the second type node, the login information for logging in the cloud platform is sent to the first type node through the low-power-consumption device, then the high-power-consumption module and the main processor module are subjected to power-off processing through the low-power-consumption control module, namely the high-power-consumption device in the high-power-consumption module is switched to a second dormant state, and then the low-power-consumption device in the low-power-consumption broadcasting module is switched to the first dormant state through the low-power-consumption control module, so that the power consumption of the node is furthest reduced on the basis that the node can receive a transmission request.

Optionally, the low power device in the first sleep state may periodically receive a transmission request sent by the first type node, and the periodic time may be set according to the actual application requirement, for example, 2 s.

Step 706: responding to the node identification in the transmission request received by the low-power-consumption device to be matched with the preset identification of the low-power-consumption device, switching the high-power-consumption device into an enabling state, and sending a push flow request to the main processor module;

In response to the transmission request received through the low-power device, and the node identifier in the transmission request is matched with the preset identifier of the low-power control module, the low-power control module powers on the main processor module and the high-power module, that is, switches the high-power device in the high-power module to an enabled state, sends a push flow request to the main processor module, and then repeatedly executes step 702. Wherein, push request characterization requires pushing video information to the cloud platform.

Step 707: judging whether an agent request sent by a second class node is received within preset waiting time;

the first type node is used for receiving a transmission request sent by the cloud platform; the second class node is used for receiving the transmission request forwarded by the first class node. That is, the second class node cannot receive the transmission request sent by the cloud platform, but the first class node is used as an intermediate object of the transmission request to receive the transmission request. After the nodes are determined to be the first class nodes, the proxy requests sent by the second class nodes are required to be acquired, so that the proxy of the second class nodes is realized.

Therefore, the node also needs to determine whether the proxy request sent by the second class node is received within the preset waiting time: if not, go to step 708; if yes, go to step 709.

Step 708: dormancy is performed for a certain time;

after a certain period of dormancy, the node repeats step 707.

Step 709: switching the high-power-consumption device to a first sleep state and switching the low-power-consumption device to a second sleep state;

if the node is the first type node, collecting the login information of the node and the login information of the second type node of the agent, and transmitting the collected login information to the low-power consumption control module. And then the low-power control module takes over the high-power module and the low-power broadcast module, and simultaneously the low-power control module performs power-off processing on the main processor module. And sending login information to the cloud platform through the high-power consumption module so as to finish registration on the cloud platform.

After the registration is completed, the low-power-consumption control module is used for carrying out power-off processing on the low-power-consumption broadcasting module, namely, the low-power-consumption devices in the low-power-consumption control module are switched into a second dormant state. And switching the high-power-consumption devices in the high-power-consumption modules to a first dormant state through the low-power-consumption control modules, namely, receiving a transmission request sent by the cloud platform based on the high-power-consumption devices in the high-power-consumption modules, and periodically sending heartbeat packets to the cloud platform based on the high-power-consumption devices in the high-power-consumption modules so as to maintain connection of the cellular links.

Step 7010: in response to receiving a transmission request through the high-power-consumption device, waking up a corresponding node based on a node identifier in the transmission request to perform remote information transmission;

in response to receiving a transmission request through a high-power-consumption device, judging whether a node identifier in the transmission request is matched with a preset identifier of the node identifier or not: if yes, switching the high-power-consumption device of the cloud platform from a first dormant state to an enabling state, and transmitting video information to the cloud platform through the enabled high-power-consumption device; if not, transmitting the transmission request to the second class node in a broadcast mode, so that the second class node matched with the node identification enables the high-power-consumption device to transmit video information to the cloud platform.

In summary, in the low power mode, only the high power devices of the first type node are in the first sleep state to receive the transmission request sent by the remote platform, and the low power devices of the first type node are in the second sleep state, i.e. have no power consumption; the second class node is only in the first dormant state for receiving the transmission request forwarded by the first class node, and the high-power device of the second class node is in the second dormant state, namely, no power consumption.

Further, the first class nodes and the second class nodes are classified according to the transmitting power of the low-power-consumption devices and the number of the coverage nodes, the lower transmitting power of the low-power-consumption devices is used as the first class nodes by using the nodes which cover more nodes, the other nodes are used as the second class nodes, and the low-power-consumption devices adopt wireless broadcasting which can realize low power consumption, so that the effect of further reducing the power consumption can be achieved compared with the effect of fixing the transmitting power.
