In order to improve the accuracy of determining the connection state of a device when determining the connection state of the device, embodiments of the present application provide a method, an apparatus, an electronic device, and a medium for determining the connection state of the device.

Fig. 1 is a schematic structural diagram of a system for determining a connection state of a device according to an embodiment of the present disclosure. The system comprises a user terminal, a monitoring platform, a lower platform and at least one monitoring device. Further, the system may also include only the user terminal, the monitoring platform, and the at least one monitoring device, which is not limited herein.

A 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 check 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.

A monitoring platform: the server may be configured to acquire a device detection connection state uploaded by the monitoring device in a query and/or subscription manner, determine an actual device connection state of the monitoring device in a manner of determining whether the multimedia data of the monitoring device can be acquired, send the actual device connection state of the monitoring device to the monitoring client, update the connection state of the device (i.e., the actual device connection state) displayed by the monitoring client, and send the multimedia data shot by the monitoring device to the monitoring client based on a multimedia data viewing request of the monitoring client, so that a user may play a monitoring video through the monitoring client.

It should be noted that the device detection connection state is a connection state of the monitoring device obtained by a self-detection manner of the monitoring device. The actual connection state of the device is the connection state of the monitoring device determined by whether the multimedia data of the monitoring device can be acquired or not. The method for detecting the connection state of the monitoring equipment comprises the steps of detecting the connection state of the monitoring equipment by the monitoring equipment, wherein the connection state of the monitoring equipment is detected by the monitoring equipment, and the connection state of the monitoring equipment is detected by the monitoring equipment.

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

A lower platform: the server may be configured to acquire a device detection connection state of the connected monitoring device according to a query instruction or a subscription instruction of the monitoring platform, and upload the acquired device detection connection state to the monitoring platform, and further configured to acquire multimedia data monitored by the monitoring device according to a multimedia start operation instruction of the monitoring platform, and upload the acquired multimedia data to the monitoring platform.

The monitoring equipment: one or more than one, which are devices for monitoring, such as a camera and a video camera. The monitoring equipment can be directly connected with the monitoring platform or can be connected with the monitoring platform through a lower platform. The monitoring device can detect the connection state according to a query instruction or a subscription instruction sent by the monitoring platform or the lower platform, and directly upload the device detection connection state to the server in real time or when the state change is determined, or upload the device detection connection state to the monitoring platform through the lower platform.

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

Referring to fig. 2, an implementation flow chart of a method for determining a connection state of a device according to an embodiment of the present application is shown, and with reference to 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 to request the monitoring device to upload the collected multimedia data, i.e., the monitoring video, in real time.

When step 200 is executed and it is determined that at least one of the following sending triggering conditions is met, the monitoring platform sends a multimedia starting request message to the monitoring device:

mode 1: and if the connection detection 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 in response to reaching the first trigger period of the second monitoring device, sending a multimedia initiation request message to the second monitoring device.

In one embodiment, if it is determined that the total number of devices is lower than the specified number threshold, a multimedia initiation request message is sent to the second monitoring device according to a first trigger cycle.

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 the devices is the number of the monitoring devices directly or indirectly connected with the monitoring platform.

Therefore, when the total number of the devices is small, the multimedia starting request message can be sent to each monitoring device by adopting the periodical convenience.

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

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

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 the devices is determined not to be lower than the specified number threshold, a multimedia starting request message is sent to the screened connection monitoring devices according to a second trigger cycle.

The offline monitoring equipment is the monitoring equipment with the actual connection state of the equipment in the offline state.

In practical applications, the first trigger period, the second trigger period, and the specified number threshold may all be set according to practical application scenarios, for example, the first trigger period and the second trigger period may be 5s, the specified number threshold 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 starting instruction of the user for the third monitoring equipment is determined to be received, sending a multimedia starting request message to the third monitoring equipment.

In one embodiment, the user sends a multimedia start instruction for the third monitoring device to the monitoring platform through an application page of the monitoring client. And the monitoring platform sends a multimedia starting request message to the third monitoring equipment through the lower 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, and may also be an online monitoring device, which is not limited herein. The online monitoring equipment is the monitoring equipment with the actual connection state of the equipment in an online state.

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

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

In practical application, the manners of sending the multimedia initiation request message may be combined arbitrarily, and the execution sequence of the combined manners may also be set according to a practical application scenario, which is not limited herein.

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

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

the first mode is as follows: and if the initialization instruction aiming at the connected first monitoring equipment is determined to be received, sending a state request message to the first monitoring equipment, and receiving an equipment detection connection state returned by the first monitoring equipment based on the state request message.

Specifically, when it is determined that the initialization instruction for the first monitoring device is received, the monitoring platform sends a status 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, acquiring an 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 may also send a status request message to the first monitoring device through the lower platform and receive a device detection connection status returned by the first monitoring device through the lower platform, which is not described herein again.

Therefore, when the initialization instruction aiming at 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 further, in the subsequent steps, the multimedia starting request message can be sent to the first monitoring device so as to obtain the actual device connection state of the first monitoring device.

The second mode is as follows: and sending a state subscription message to the first monitoring equipment, and receiving a 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 receiving the state subscription message, the first monitoring equipment carries out self-detection on the connection state in real time. When the connection state change is detected, the first monitoring equipment acquires the changed equipment detection connection state and returns the changed equipment detection connection state to the monitoring platform through the lower platform.

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

It should be noted that, when the monitoring device has just changed its state, the accuracy of obtaining the actual connection state of the device is usually the highest, so the monitoring platform may send the multimedia start request message to the first monitoring device in real time 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.

Therefore, after receiving the device detection connection state returned by one or more monitoring devices, the multimedia startup request message can be sent to the corresponding monitoring device to obtain the actual connection state of the corresponding device.

Step 201: the monitoring platform judges whether multimedia data returned by the monitoring device based on the multimedia starting request message is received in the response time period, if so, step 202 is executed, otherwise, step 203 is executed.

Specifically, if the multimedia data returned by the monitoring device is received within the set response time period, the monitoring platform determines that the actual connection state of the monitoring device is an online state, otherwise, determines that the actual connection state of the monitoring device is an offline state.

In practical applications, the set response time period may be set according to practical application scenarios, such as 2s, and is not limited herein.

If the actual connection state of the monitoring device is the online state, it indicates that the monitoring device successfully receives the multimedia start request message sent by the monitoring platform, and successfully uploads the multimedia data obtained by real-time monitoring to the monitoring platform directly or indirectly.

If the actual connection state of the device of one monitoring device is the offline state, it indicates that the monitoring device does not receive the multimedia start request message sent by the monitoring platform, or the monitoring device successfully receives the multimedia start request message sent by the monitoring platform, but does not successfully upload the multimedia data obtained by real-time monitoring to the monitoring platform.

Step 202: and the monitoring platform determines that the actual connection state of the monitoring equipment is an online state.

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

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

When the actual connection state of the equipment 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: and after the actual connection state of the monitoring equipment is determined, updating the displayed actual connection state of the monitoring equipment in the application page in real time.

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

When the first trigger period and/or the second trigger period are determined, the following steps may be adopted:

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

S2032: and determining the reliability and/or the state change frequency of the equipment detection connection state of the monitoring equipment according to at least one of the equipment detection connection state of the monitoring equipment and the actual equipment connection state 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: and if the monitoring equipment connected with the monitoring platform through the lower platform exists, the monitoring platform determines the credibility of the monitoring equipment connected with the lower platform according to at least one of the equipment detection connection state of the monitoring equipment connected with the lower platform and the actual connection state of the monitoring equipment.

In one embodiment, if there is a monitoring device connected to the monitoring platform through the lower platform, when the monitoring platform determines that the device of the monitoring device connected to the monitoring platform through the lower platform detects the reliability of the connection state, the following steps may be performed:

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

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

The second step is that: and counting the number of the unreliable devices of which the latest detection connection states of the devices of the plurality of monitoring devices connected to the same lower-level platform are inconsistent with the actual connection states of the corresponding devices.

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

And if the latest detection connection state of the monitoring equipment is inconsistent with the actual connection state of the corresponding equipment, indicating that the equipment detection connection state of the monitoring equipment is inaccurate.

The third step: and determining the credibility of the lower platform according to the number of the devices corresponding to the lower platform and the number of the devices which cannot be trusted.

The credibility of the lower platform is negatively related to the number of the untrusted devices and the number of the 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 differ is determined as the trustworthiness of the lower level platform.

The fourth step: and determining the credibility of the lower platform as the credibility of a plurality of monitoring devices connected to the lower platform.

Mode 2: and if the 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 to the monitoring platform, the following steps may be adopted:

The second step is that: and counting the number of the unreliable 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.

The third step: 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 untrustworthy equipment.

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

The second step is that: and counting the number of the untrusted devices, which are directly connected with the monitoring platform and are connected with the monitoring platform through the lower platform, of the devices of the plurality of monitoring devices, wherein the number of the untrusted devices is inconsistent with the actual connection state of the corresponding devices in the latest detection connection state.

The third step: and determining the credibility of the monitoring equipment which is directly connected with the monitoring platform and is connected with the lower-level platform according to the number of the equipment and the number of the untrustworthy equipment which are directly connected with the monitoring platform and are connected with the lower-level platform.

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

In practical applications, the above modes may be combined in any mode, and may also be executed in any order, which is not limited herein.

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 a specified time period.

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

In one embodiment, the ratio of the average value of the change times to the specified time period is determined as the state change frequency of each monitoring device.

Mode 2: and determining the state change frequency of the monitoring equipment according to the change times of the actual connection state of the monitoring equipment in a specified time period.

S2033: and determining a first trigger period and/or a second trigger period according to the reliability and/or the state change frequency of the device detection connection state of the monitoring device.

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

mode 1: and 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.

For example, assuming that the determined confidence level is 30%, the confidence level condition is: if the determined reliability is lower than 50%, a first duration set for the reliability, namely 1 minute, is determined as a first trigger period.

Mode 2: and if the state change frequency meets the change frequency condition, determining a second duration set aiming at the state change frequency as a first trigger period and/or a second trigger period.

For example, if the state change frequency is 10 times/h and the change frequency condition is that the state change frequency is higher than 5 times/h, the second time duration set for the state change frequency, that is, 5min, is determined as the first trigger period.

Mode 3: and if the reliability and the state change frequency accord with the comprehensive adjustment condition, determining a first trigger period and/or a second trigger period according to the first time length and the second time length.

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

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

The reliability condition, the change frequency condition, the synthesis and adjustment condition, the first duration and the second duration may be set according to an actual application scenario, and are not limited herein.

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

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

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

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

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

For example, the status display layer of the monitoring client in the WEB page device sends an initialization instruction to the upper international standard 28181 platform (i.e., the monitoring platform).

For another example, the monitoring client sends an initialization instruction to the upper international 28181 platform in response to the initialization operation of the user on the monitoring page.

Step 302: and the monitoring platform sends a state request message to the monitoring equipment.

In one embodiment, the monitoring platform sends a status request message to the lower level platform based on the received initialization indication. And the lower platform respectively sends a state request message to each monitoring device.

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

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

In one embodiment, after determining that the status request message is received, each monitoring device performs status detection, obtains a device detection connection status, and returns the device detection connection status to the lower platform.

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

Specifically, if it is determined that the device detection connection state 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 equipment returns the multimedia data to the monitoring platform.

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

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

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

Specifically, the monitoring platform sends the actual connection state of the monitoring device 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: and the monitoring platform determines the reliability and the state change frequency according to the equipment detection connection state and the actual connection state of each monitoring device.

For example, if the total number of the monitoring devices is 10, the number of the monitoring devices whose states are represented by the comparison result is 8, and the number of the monitoring devices whose states are represented by the comparison result is 2, the confidence level is 8/10 — 80%.

For another example, the total number 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 online states, the device detection connection states of the device a, the device B, the device C, the device D, and the device E are all offline 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 offline states, and the device actual connection states of the device a, the device B, the device C, the device D, and the device are all online states, and then the reliability is determined to be 0.

In one embodiment, when determining the frequency of the state change, the monitoring platform may adopt the following steps:

s3091: and respectively determining the number of times of changing the actual connection state of the equipment in a specified time period by each monitoring equipment.

In practical applications, the specified time period may be set according to practical application scenarios, 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 number of offline monitoring devices in the online state is determined, and when the number of offline monitoring devices is lower than a threshold value of the specified number, the second trigger period is adjusted according to the reliability and the state change frequency.

It should be noted that, the higher the confidence level is, the higher the accuracy of detecting the connection state by the device is, the longer the traversal period, that is, the first trigger period and the second trigger period, may be set, and conversely, the shorter the traversal period is set. Moreover, the higher the state change frequency is, it indicates that the connection state of the monitoring device is changed frequently, and there may be a problem that a network cable is not plugged, and the like, and the traversal period needs to be reduced to improve the traversal frequency, otherwise, the traversal period can be improved.

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

In one embodiment, if it is determined that the device detection connection status 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 equipment 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.
