It is also contemplated that the terminal device can support any type of interface (e.g., wearable device) for the user, etc.

And (3) a server: the cloud server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, basic cloud computing services such as big data and artificial intelligent platforms and the like.

In order to improve accuracy of connection state determination of equipment when determining the connection state of the equipment, the embodiment of the application provides a method, a device, electronic equipment and a medium for determining the connection state of the equipment.

Referring to fig. 1, a schematic architecture diagram of a system for determining a connection state of a device according to an embodiment of the present application is shown. The system comprises a user terminal, a monitoring platform, a subordinate platform and at least one monitoring device. Further, the system may also include only the user terminal, the monitoring platform, and at least one monitoring device, which is not limited herein.

User terminal: may be a terminal device installed with a monitoring client. The monitoring client can acquire the connection state of the monitoring equipment, multimedia data shot by the monitoring equipment and the like through the monitoring platform.

The monitoring client may be a video client or a browser, etc. The user can view the connection state of the monitoring equipment through the video client or the browser page, and can play the monitoring video through the WEB page in the video client or the browser.

And (3) a monitoring platform: the method can be a server, and is used for acquiring the device detection connection state uploaded by the monitoring device in a query and/or subscription mode, determining the device actual connection state of the monitoring device in a mode of whether the device can acquire the multimedia data of the monitoring device, and sending the device actual connection state of the monitoring device to the monitoring client so as to update the connection state (namely the device actual connection state) of the device displayed by the monitoring client, and sending the multimedia data shot by the monitoring device to the monitoring client based on the multimedia data viewing request of the monitoring client, so that a user can play a monitoring video through the monitoring client.

The device detecting connection state is obtained by the monitoring device in a self-detecting manner. The actual connection state of the device is the connection state of the monitoring device determined by means of whether the multimedia data of the monitoring device can be acquired or not. The accuracy of detecting the connection state of the equipment is lower, the operation is simple, the accuracy of detecting the actual connection state of the equipment is higher, the operation is complex, therefore, when the number of the monitoring equipment is small, the actual connection state of the equipment of each monitoring equipment can be directly obtained to judge whether each monitoring equipment is in an on-line state, and when the number of the monitoring equipment is large, the mode of obtaining the actual connection state of the equipment is combined with the mode of obtaining the detection connection state of the equipment to judge whether each monitoring equipment is in the on-line state.

Optionally, the monitoring platform may be directly connected to the monitoring device in a communication manner, or may be connected to the monitoring device in a communication manner through a lower platform, which is not limited herein.

The lower stage platform: the method can be a server, and is used for acquiring the equipment detection connection state of the connected monitoring equipment according to the query instruction or the subscription instruction of the monitoring platform, uploading the acquired equipment detection connection state to the monitoring platform, acquiring the multimedia data monitored by the monitoring equipment according to the multimedia starting operation instruction of the monitoring platform, and uploading the acquired multimedia data to the monitoring platform.

Monitoring equipment: the number of the devices can be one or more, and the devices can be used for monitoring, such as a camera, a video camera and the like. The monitoring equipment can be directly connected with the monitoring platform, and also can be connected with the monitoring platform through a lower-level platform. The monitoring equipment can detect the connection state according to the inquiry instruction or the subscription instruction sent by the monitoring platform or the lower-level platform, and directly upload equipment to the server to detect the connection state in real time or when determining state change, or upload equipment to the monitoring platform to detect the connection state.

The device detection connection state refers to a connection state between the monitoring device and the monitoring platform, which is obtained in a self-detection mode, and is used for indicating whether the monitoring device is in an on-line state or an off-line state.

Referring to fig. 2, a flowchart of an implementation of a method for determining a connection state of a device according to an embodiment of the present application is shown, and in conjunction with the system for determining a connection state of a device in fig. 1, a specific implementation flow of the method is as follows:

step 200: and when the monitoring platform determines that the sending triggering condition is met, sending a multimedia starting request message to the monitoring equipment.

Specifically, the multimedia start request message is used for requesting the monitoring device to upload the collected multimedia data, i.e. the monitoring video, in real time.

When step 200 is executed, the monitoring platform sends a multimedia start request message to the monitoring device when determining that at least one of the following modes is met:

mode 1: and if the equipment detection connection state reported by the first monitoring equipment is determined to be received, sending a multimedia starting request message to the first monitoring equipment.

The first monitoring device may be any one of the monitoring devices connected to the monitoring platform, which is not limited herein.

Mode 2: and transmitting a multimedia start request message to the second monitoring device in response to reaching the first trigger period of the second monitoring device.

In one embodiment, if the total number of devices is determined to be below the specified number threshold, a multimedia activation request message is sent to the second monitoring device in accordance with the first trigger period.

The second monitoring device may be any one of the monitoring devices connected to the monitoring platform, which is not limited herein. The total number of devices is the number of monitoring devices to which the monitoring platform is directly or indirectly connected.

In this way, when the total number of devices is small, the periodic convenience can be adopted, and the multimedia start request message can be sent to each monitoring device.

Further, mode 1 may be combined with mode 2, i.e. the starting time of the first trigger period timing may be determined according to the time when the multimedia start request message is first sent to the second monitoring device.

In one embodiment, if it is determined that the device detecting the connection state reported by the second monitoring device is received, a multimedia start request message is first sent to the second monitoring device, and in response to reaching the first trigger period of the second monitoring device, the multimedia start request message is sent again to the second monitoring device.

Mode 3: and in response to reaching the second trigger period of the offline monitoring device, sending a multimedia start request message to the offline monitoring device.

In one embodiment, if the total number of devices is not less than the specified number threshold, a multimedia start request message is sent to the screened offline monitoring devices according to the second trigger period.

The off-line monitoring equipment is monitoring equipment with the actual connection state of the equipment in an off-line state.

In practical application, the first trigger period, the second trigger period and the specified number of thresholds may be set according to the practical application scenario, for example, the first trigger period and the second trigger period may be 5s, the specified number of thresholds may be 10, and the first trigger period and the second trigger period may be the same or different, which is not limited herein.

Mode 4: and if the multimedia start instruction of the user for the third monitoring equipment is determined to be received, sending a multimedia start request message to the third monitoring equipment.

In one embodiment, the user sends a multimedia activation indication for the third monitoring device to the monitoring platform through the application page of the monitoring client. And the monitoring platform sends a multimedia starting request message to the third monitoring equipment through the lower-level platform or directly according to the received multimedia starting instruction.

The third monitoring device may be any one of the monitoring devices connected to the monitoring platform, or may be an online monitoring device, which is not limited herein. The on-line monitoring equipment is monitoring equipment with the actual connection state of the equipment in an on-line state.

Further, when the multimedia start request message is sent, mode 3 may be combined with mode 4.

In one embodiment, a multimedia activation request message is sent to the offline monitoring device in response to reaching a second trigger period of the offline monitoring device. And if the multimedia start instruction of the user for the online monitoring equipment is determined to be received, sending a multimedia start request message to the online monitoring equipment.

In practical application, the above modes of sending the multimedia start request message may be arbitrarily combined, and the execution sequence of each mode after combination may be set according to the practical application scenario, which is not limited herein.

Because the user usually views the multimedia video of the monitoring device in the online state, but rarely views the multimedia video of the monitoring device in the offline state, when the total number of the monitoring devices is small, the device actual connection state of each monitoring device can be periodically obtained in a traversing manner, however, when the total number of the monitoring devices is large, in order to reduce the system resources consumed by state maintenance, the device actual connection state of each monitoring device in the offline state can be traversed only, and the corresponding device actual connection state can be obtained for the monitoring device in the online state based on the user indication.

When the monitoring platform obtains the device detection connection state of the monitoring device, any one or any combination of the following modes can be adopted:

the first way is: and if the initialization instruction of the connected first monitoring equipment is received, sending a state request message to the first monitoring equipment, and receiving equipment detection connection state returned by the first monitoring equipment based on the state request message.

Specifically, when the initialization instruction for the first monitoring device is determined to be received, the monitoring platform sends a state request message to the first monitoring device. And after the first monitoring equipment determines that the state request message sent by the monitoring platform is received, performing connection state self-detection to obtain equipment detection connection state, and returning the equipment detection connection state to the monitoring platform. And the monitoring platform receives the equipment detection connection state returned by the first monitoring equipment.

Similarly, the monitoring platform can also send a status request message to the first monitoring device through the lower-level platform and receive the device detection connection status returned by the first monitoring device through the lower-level platform, which is not described herein.

In this way, when the initialization instruction for the first monitoring device is determined to be received, the device detection connection state of the first monitoring device can be obtained in real time, and then a multimedia start request message can be sent to the first monitoring device in a subsequent step so as to obtain the actual device connection state of the first monitoring device.

The second way is: and sending a state subscription message to the first monitoring equipment, and receiving the changed equipment detection connection state returned when the first monitoring equipment detects the state change.

In one embodiment, the monitoring platform sends a status subscription message to the first monitoring device through the lower platform. And after the first monitoring equipment receives the state subscription message, the first monitoring equipment automatically detects the connection state in real time. When the connection state change is detected, the first monitoring device acquires the changed device detection connection state and returns the changed device detection connection state to the monitoring platform through the lower platform.

Furthermore, the monitoring platform may also send a status request message to one or more monitoring devices selected by the user according to the user's instruction, so as to obtain a corresponding device detection connection status, which is not described herein.

It should be noted that, when the monitoring device just changes the state, the accuracy of obtaining the actual connection state of the device is generally the highest, so the monitoring platform may send, in real time, a multimedia start request message to the first monitoring device after determining that the connection state detected by the device returned by the first monitoring device is received, so as to obtain the accurate actual connection state of the device of the first monitoring device.

In this way, after receiving the connection state detected by the device returned by one or more monitoring devices, a multimedia start request message is sent to the corresponding monitoring device, so as to obtain the actual connection state of the corresponding device.

Step 201: the monitoring platform determines whether the multimedia data returned by the monitoring device based on the multimedia start request message is received within the response time period, if yes, step 202 is executed, otherwise step 203 is executed.

Specifically, if the multimedia data returned by the monitoring equipment is received within the set response time period, the monitoring platform determines that the actual equipment connection state of the monitoring equipment is an on-line state, otherwise, determines that the actual equipment connection state of the monitoring equipment is an off-line state.

In practical application, the set response time period may be set according to a practical application scenario, for example, 2s, which is not limited herein.

If the actual connection state of the device of one monitoring device is an on-line state, the monitoring device is indicated to successfully receive the multimedia start request message sent by the monitoring platform, and the multimedia data obtained by real-time monitoring is successfully uploaded to the monitoring platform directly or indirectly.

If the actual connection state of the device of one monitoring device is an offline state, the monitoring device is not informed of receiving the multimedia start request message sent by the monitoring platform, or the monitoring device is successful in receiving the multimedia start request message sent by the monitoring platform, but is not successful in uploading the multimedia data obtained by real-time monitoring to the monitoring platform.

Step 202: the monitoring platform determines that the actual connection state of the equipment of the monitoring equipment is an on-line state.

Step 203: the monitoring platform determines that the actual connection state of the equipment of the monitoring equipment is an offline state.

Furthermore, after receiving the actual connection state of the monitoring device, the monitoring platform can also store the actual connection state of the monitoring device and the device in an associated manner, and display the actual connection state of the monitoring device in real time through an application page.

When the actual connection state of the monitoring equipment is displayed, the following two modes can be adopted:

mode 1: and sending the actual connection state of the monitoring equipment to the monitoring client in real time. And after receiving the actual connection state of the monitoring equipment, the monitoring client updates the displayed actual connection state of the monitoring equipment in the application page.

Mode 2: after the actual connection state of the monitoring device is determined, the displayed actual connection state of the monitoring device is updated in real time in the application page.

Further, the first trigger period and/or the second trigger period may also be updated in real time or periodically according to at least one of the device detection connection status of the monitoring device and the device actual connection status of the monitoring device.

Wherein, when determining the first trigger period and/or the second trigger period, the following steps may be adopted:

s2031: and receiving the equipment detection connection state reported by the monitoring equipment.

S2032: and determining the reliability of the detection of the connection state of the equipment of the monitoring equipment and/or the state change frequency according to at least one of the detection of the connection state of the equipment of the monitoring equipment and the actual connection state of the equipment of the monitoring equipment.

When determining the reliability of the device detection connection state of the monitoring device, the monitoring platform may adopt any one or a combination of the following modes:

mode 1: if monitoring equipment connected with the monitoring platform through the lower-stage platform exists, the monitoring platform determines the credibility of the monitoring equipment connected with the lower-stage platform according to at least one of the equipment detection connection state of the monitoring equipment connected with the lower-stage platform and the actual equipment connection state of the monitoring equipment.

In one embodiment, if there is a monitoring device connected to the monitoring platform through the lower stage platform, the monitoring platform may determine the reliability of detecting the connection state by the device of the monitoring device connected to the monitoring platform through the lower stage platform, where the following steps may be adopted:

the first step: and acquiring the latest detection connection state reported by the monitoring equipment.

The latest detection connection state is the device detection connection state reported by the monitoring device for the last time before the actual connection state of the device is acquired.

And a second step of: and counting the number of the untrusted devices, of which the latest detection connection states of the devices connected to the plurality of monitoring devices of the same subordinate platform are inconsistent with the actual connection states of the corresponding devices.

The number of the lower-stage platforms may be one or more, and is not limited herein.

If the latest detection connection state of the monitoring equipment is inconsistent with the actual connection state of the corresponding equipment, the detection connection state of the equipment of the monitoring equipment is inaccurate.

And a third step of: and determining the credibility of the lower platform according to the number of the devices and the number of the un-credible devices corresponding to the lower platform.

The reliability of the lower-level platform is inversely related to the number of untrusted devices and the number of devices.

In one embodiment, a difference between the number of devices and the number of untrusted devices is determined, and a ratio of the number of devices that are the difference is determined as the trustworthiness of the lower level platform.

Fourth step: the reliability of the lower stage is determined as the reliability of a plurality of monitoring devices connected to the lower stage.

Mode 2: if monitoring equipment directly connected with the monitoring platform exists, the monitoring platform determines the credibility of the directly connected monitoring equipment according to at least one of the equipment detection connection state of the directly connected monitoring equipment and the actual equipment connection state of the monitoring equipment.

Specifically, when the monitoring platform determines the reliability of the device detection connection state of the monitoring device directly connected with the monitoring platform, the following steps may be adopted:

And a second step of: and counting the number of the untrusted devices, of which the latest detection connection states of the devices of the plurality of monitoring devices directly connected with the monitoring platform are inconsistent with the actual connection states of the corresponding devices.

And a third step of: and determining the credibility of the monitoring equipment directly connected with the monitoring platform according to the number of the equipment directly connected with the monitoring platform and the number of the unreliable equipment.

Mode 3: the monitoring platform determines the credibility of each monitoring device according to at least one of the device detection connection state of each monitoring device and the device actual connection state of the monitoring device.

Specifically, when the monitoring platform determines the reliability of the device detection connection state of the monitoring device, the following steps may be adopted:

And a second step of: and counting the number of the untrusted devices, the connection state of which is not consistent with the actual connection state of the corresponding device, of the latest detection of the devices of the monitoring devices directly connected with the monitoring platform and connected with the monitoring platform through the lower-level platform.

And a third step of: and determining the credibility of the monitoring equipment directly connected with the monitoring platform and connected with the lower-level platform according to the number of the equipment directly connected with the monitoring platform and connected with the lower-level platform and the number of the unreliable equipment.

Optionally, if there is a monitoring device directly connected to the monitoring platform, or there is a monitoring device connected to the monitoring platform through a lower platform, the reliability of each monitoring device may be determined by combining the above mode 1 and the above mode 2, or the reliability of each monitoring device may be determined only by adopting the above mode 3.

In practical applications, the above embodiments may be combined in any manner, or may be executed in any order, which is not limited herein.

Wherein, when determining the state change frequency of the monitoring device, any one or combination of the following modes can be adopted:

mode 1: and determining the state change frequency of the monitoring equipment according to the change times of the equipment detection connection state of the monitoring equipment in the designated time period.

In one embodiment, the ratio of the number of changes of each monitoring device to the designated time period is determined as the status change frequency of the monitoring device.

In one embodiment, the ratio of the average value of the number of changes to the designated time period is determined as the status change frequency of each monitoring device.

Specifically, when S2033 is executed, at least one of the following manners may be adopted:

mode 1: if the credibility meets the credibility condition, determining a first duration set for the credibility as a first trigger period and/or a second trigger period.

In one embodiment, the maximum or minimum of the first and second time periods is determined as the first and/or second trigger periods.

For example, assume that the sum adjustment conditions are: if the determined reliability is lower than 50%, the state change frequency is higher than 5 times/h, determining that the first time length is 1 minute, the second time length is 5 minutes, and determining that the maximum value of the first time length and the second time length is 5 minutes as a second trigger period.

The reliability condition, the frequency change condition, the sum adjustment condition, the first duration and the second duration can be set according to the actual application scene, and are not limited herein.

The above embodiments are further described below using several specific application scenarios.

Scene 1: referring to fig. 3, an interaction diagram of a method for initializing a device according to an embodiment of the present application is shown, and in combination with the system for determining a connection state of a device in fig. 1, a specific implementation flow of the method is as follows:

Step 301: and the monitoring client sends an initialization instruction to the monitoring platform.

Specifically, when the monitoring client determines that the device is initialized, the monitoring client sends an initialization instruction for updating the state to the monitoring platform.

Optionally, the monitoring platform may be an upper-level national standard 28181 platform, and the monitoring client may be a WEB page client.

For example, the state presentation layer of the monitoring client in the WEB page device sends an initialization indication to the upper-level national standard 28181 platform (i.e., the monitoring platform).

For another example, the monitoring client sends an initialization indication to the superior national standard 28181 platform in response to an initialization operation of the user for the monitoring page.

Step 302: the monitoring platform sends a status request message to the monitoring device.

In one embodiment, the monitoring platform sends a status request message to the subordinate platform based on the received initialization indication. The subordinate platform respectively sends a status request message to each monitoring device.

The state request message is used for requesting to acquire the current equipment detection connection state of the monitoring equipment.

Step 303: the monitoring equipment returns equipment detection connection state to the monitoring platform.

In one embodiment, after each monitoring device determines that the status request message is received, status detection is performed, a device detection connection status is obtained, and the device detection connection status is returned to the lower platform.

Step 304: the monitoring platform sends a multimedia start request message to the monitoring equipment.

Specifically, if it is determined that the connection state detected by the device returned by any monitoring device is received, the monitoring platform sends a multimedia start request message to any monitoring device through the lower platform.

Step 305: the monitoring device returns the multimedia data to the monitoring platform.

Step 306: and the monitoring platform determines the actual connection state of the devices of each monitoring device according to whether the returned multimedia data are received or not.

Step 307: the monitoring client receives the actual connection state of each monitoring device sent by the monitoring platform.

Step 308: the monitoring client displays the actual connection state of the devices of each monitoring device.

Specifically, the monitoring platform sends the actual connection state of the monitoring equipment to the monitoring client in real time. And after receiving the actual connection state of the monitoring equipment, the monitoring client updates the displayed actual connection state of the monitoring equipment in the application page.

Step 309: the monitoring platform determines the credibility and the state change frequency according to the equipment detection connection state and the actual equipment connection state of each monitoring equipment.

Specifically, when determining the reliability, the monitoring platform may employ the following steps:

And comparing the equipment detection connection state and the equipment actual connection state of each monitoring equipment, determining the equipment number of the monitoring equipment with consistent characterization state in each monitoring equipment, and determining the credibility according to the ratio between the total number of the equipment and the total number of each monitoring equipment.

For example, the total number of devices of the monitoring devices is 10, the number of devices of the monitoring devices with consistent state is 8 as compared with the number of devices of the monitoring devices with inconsistent state is 2 as compared with the result, and the reliability is 8/10=80%.

For another example, the total number of devices of the monitoring devices is 10, the device detection connection states of the device a, the device B, the device C, the device D and the device E are all on-line states, the device detection connection states of the device a, the device B, the device C, the device D and the device are all off-line states, the device actual connection states of the device a, the device B, the device C, the device D and the device E are all off-line states, and the reliability is determined to be 0.

In one embodiment, when determining the status change frequency, the monitoring platform may employ the following steps:

S3091: and respectively determining the change times of the actual connection state of the equipment of each monitoring equipment in the appointed time period.

In practical application, the specified time period may be set according to a practical application scenario, for example, the specified time period may be 5s, which is not limited herein.

S3092: and determining the state change frequency according to the change times of each monitoring device.

Step 310: and the monitoring platform determines a first trigger period and/or a second trigger period according to the reliability and the state change frequency.

In one embodiment, the monitoring platform obtains the total number of devices of each monitoring device, and determines whether the total number of devices is lower than a specified number threshold, if yes, determines a first trigger period according to the reliability and the state change frequency, and if not, determines a second trigger period according to the reliability and the state change frequency.

In one embodiment, determining the offline number of the monitoring device in the online state, and adjusting the second trigger period according to the reliability and the state change frequency when the offline number is determined to be lower than the specified number threshold.

It should be noted that, the higher the reliability, the higher the accuracy of detecting the connection state by the device, the longer the traversal period, that is, the first trigger period and the second trigger period, may be set, otherwise, the shorter the traversal period is set. Furthermore, the higher the state change frequency is, the more frequently the connection state of the monitoring device is changed, and the problems that the network cable is not plugged in and the like may exist, so that the traversing period needs to be reduced to improve the traversing frequency, otherwise, the traversing period can be improved.

Scene 2: and detecting the state of the monitoring equipment by adopting a state subscription mode. Referring to fig. 4, an interaction diagram of a subscription detection method of a device according to an embodiment of the present application is shown, and in combination with the system for determining a connection state of a device in fig. 1, a specific implementation flow of the method is as follows:

step 401: the monitoring platform sends a status subscription message to the monitoring device.

In one embodiment, the monitoring platform sends a status subscription message to a lower platform, and the lower platform sends the status subscription message to each monitoring device respectively.

Step 402: and when the monitoring equipment detects the state change, returning the changed equipment detection connection state to the monitoring platform.

In one embodiment, when each monitoring device detects a state change, the changed device detection connection state is returned to the lower platform. And the subordinate platform returns the equipment detection connection state to the monitoring platform.

Step 403: the monitoring platform sends a multimedia start request message to the monitoring equipment.

In one embodiment, if it is determined that the device detection connection state sent by any monitoring device is received, the monitoring platform sends a multimedia start request message to the corresponding monitoring device through the lower platform.

Step 404: the monitoring device returns the multimedia data to the monitoring platform.

Step 405: and the monitoring platform determines the actual connection state of the corresponding monitoring equipment according to whether the returned multimedia data is received or not.

Step 406: and the monitoring platform returns the actual connection state of the corresponding monitoring equipment to the monitoring client.

Referring to fig. 5, a flowchart of an implementation of a method for detecting traversal of a device according to an embodiment of the present application is shown, and in combination with the system for determining a connection state of a device in fig. 1, a specific implementation flow of the method is as follows:

step 500: the monitoring platform obtains the total number of the devices of each monitoring device.

Step 501: the monitoring platform determines whether the total number of devices is lower than a specified number threshold, if so, then step 502 is executed, otherwise, step 507 is executed.

Step 506: the monitoring client updates and displays the actual connection state of the corresponding monitoring equipment.

Step 507: the monitoring platform determines a second trigger period.

Step 508: according to the second trigger period, the monitoring platform sends a multimedia start request message to each monitoring device whose actual connection state is offline, and step 504 is executed.

Further, when the multimedia start instruction of the user for any monitoring device is determined to be received, the monitoring platform can also send a multimedia start request message to any monitoring device selected by the user.

Alternatively, the user may select a device from all the monitoring devices, or may select a device from only the monitoring devices that are online, which is not limited herein.
