[0002] For some electronic production factories or some special requirement companies, in order to ensure the safety of public property and improve the work efficiency and time benefit of employees, it is stipulated that employees must store mobile phones in the parking lot during working hours. If an employee takes out the mobile phone and leaves the parking lot during working hours, it is a violation. For the control of the violation phenomenon, the current control measures take manual inspection, which is divided into on-site inspection and remote monitoring inspection. However, no matter which manual inspection method is used, there are problems such as high labor cost and difficulty in abnormal traceability. SUMMARY

[0003] Therefore, the purpose of the embodiments of the present application is to provide a device state monitoring method, a server, a system, an electronic device and a computer readable storage medium, so as to reduce labor cost and improve device monitoring accuracy.

[0004] In the first aspect, the embodiments of the present application provide a device state monitoring method, comprising: acquiring a homing signal sent by a homing base station to a target device, the homing signal comprising unique identity information of the target device; acquiring a feedback signal emitted by the target device according to the homing signal; determining positioning information of the target device according to a phase difference between the homing signal and the feedback signal; and determining a state of the target device through the positioning information.

[0005] In the above implementation process, the homing base station sends a homing signal to the target device to obtain a feedback signal of the target device, and the actual position of the target device can be accurately obtained according to the phase difference between the homing signal and the feedback signal. The actual state of the target device can be further determined according to the actual position of the target device, so as to realize automatic monitoring of the target device, reduce labor input and improve monitoring accuracy.

At this time, an alarm will also be issued to remind the staff that the target device has an anomaly, and the monitoring of the target device is strengthened while the target device is monitored in real time.

If an employee takes out the mobile phone and leaves the parking lot during working hours, it is a violation. In view of the phenomenon of violation, the current control measures adopt manual inspection, which is divided into on-site inspection and remote monitoring inspection.

[0049] Please refer to Figure 3 is a flowchart of a device state monitoring method provided by the embodiment of the present application. The specific flowchart shown in Figure 3 will be described in detail.

[0050] Step 201: Obtain a seeking signal sent by a seeking base station to a target device.

[0051] The seeking signal can include unique identity information of the target device, the seeking signal can also include a direction of sending the seeking signal, the seeking signal can also include an angle of sending the seeking signal, etc.

[0052] Optionally, the target device is provided with a positioning tag corresponding to the seeking base station. The positioning tag can be a patch type, a magnetic type, etc. The positioning tag can be an application program, a plug-in, etc. The positioning tag can be set according to actual conditions, and the specific form of the positioning tag is not limited in the present application.

[0053] Step 202: Obtain a feedback signal emitted by the target device according to the seeking signal.

[0054] The feedback signal can include a boot-up state or a shut-down state of the target device, the feedback signal can include an angle at which the target device sends the feedback signal, the feedback signal can include a direction at which the target device sends the feedback signal, and the feedback signal can further include unique identity information of the target device.

[0055] Optionally, the target device can include one or more, and the feedback signal can also include one or more.

[0056] In step 203, the positioning information of the target device is determined according to the phase difference between the homing signal and the feedback signal.

[0057] Optionally, the positioning information of the target device can include position information of the target device, and the positioning information of the target device can include state information of the target device.

[0058] Optionally, the phase difference between the homing signal and the feedback signal is calculated according to the direction difference and the angle difference between the homing signal and the feedback signal, and the positioning information of the target device is calculated according to a set algorithm through the phase difference. The set algorithm can be a triangulation method, and the set algorithm can be a maximum likelihood algorithm.

[0059] For example, the state of the target device can include that the target device is not in a target area, and the state of the target device can also include that the target device is in the target area.

[0060] For example, the state of the target device can include that the target device is in a boot-up state, and the state of the target device can also include that the target device is in a shut-down state.

[0061] In one possible implementation, in step 203, the homing direction and the homing angle of the homing signal are determined according to the homing signal, the feedback direction and the feedback angle of the feedback signal are determined according to the feedback signal, the relative direction between the homing signal and the feedback signal is calculated according to the homing direction and the feedback direction, the relative angle between the homing signal and the feedback signal is calculated according to the homing angle and the feedback angle, and the positioning information of the target device is calculated according to the relative direction and the relative angle.

[0062] The homing signal is a signal sent by a homing base station for positioning the target device, and the homing manner of the homing signal can include an angle of arrival ranging method and a departure angle method.

[0063] When the homing signal is sent, a corresponding angle and direction are generated, and the angle and the direction are respectively a homing angle and a homing direction.

[0064] Wherein, the target device will generate different phase difference signals due to the different distances between each antenna in the array and the receiving device after receiving the homing signal, and these phase difference signals are the feedback signals.

[0065] Wherein, the corresponding angle and direction are fed back when the feedback signal is sent, and the angle and direction are feedback angle and feedback direction respectively.

[0066] Optionally, the relative angle between the homing signal and the feedback signal can be determined according to the phase difference between the homing angle and the feedback angle. The relative direction between the homing signal and the feedback signal can be determined according to the phase difference between the homing direction and the feedback direction. The phase difference of the target device can be calculated through the relative angle, the relative direction and the phase difference calculation formula.

[0067] Exemplarily, in the angle of arrival ranging method: the Bluetooth positioning base station transmits a special homing signal through a single antenna. The target device has an array composed of multiple antennas. When the transmitted signal passes through the antenna array, the target device will have a signal phase difference due to the different distances between each antenna in the array and the receiving device. The receiving device performs IQ sampling on the signal while switching between the transmitting antennas in the array. Based on the IQ sample data, the receiving device can calculate the relative signal direction. The receiving device can be a Bluetooth positioning base station, and the receiving device can also be a server.

[0068] Exemplarily, in the angle of departure method: the target device transmits a special homing signal through an array composed of multiple antennas. The receiving device has a single antenna. When multiple signals from the target device pass through the antenna of the receiving device, the receiving device performs IQ sampling. Based on the IQ sample data, the receiving device can calculate the relative signal direction. The receiving device can be a Bluetooth positioning base station, and the receiving device can also be a server.

[0069] In a possible implementation, step 204 comprises: determining whether the target device is in the target area according to the positioning information; and if the target device is in the target area, determining that the target device is in a normal state.

[0070] Optionally, the target area can be a parking apron, the target area can be a warehouse, the target area can be a factory building, the target area can be a workshop, etc. The target area can be selected according to actual conditions, and the application does not make specific limitations. The target area should be within the range of the Bluetooth positioning base station, which can be set above the target area or other positions around the target area.

[0071] Optionally, the position information in the positioning information is matched with the position area of the target area. If the position information of the target device can be successfully matched with the position area of the target area, it indicates that the target device is within the range of the target area.

[0072] For example, if the position of the target device is determined as area A according to the position information in the positioning information of the target device, the target area is area B, and area A is within the range of area B, it indicates that the target device is within the range of the target area, and at this time, it can be determined that the target device is in a normal state.

[0073] In a possible implementation, the device state monitoring method further includes: if the target device is not within the target area, determining that the target device is in an abnormal state; and when the target device is in the abnormal state, alarming the abnormal state.

[0074] For example, if the position of the target device is determined as area C according to the position information in the positioning information of the target device, the target area is area B, and area C is not within the range of area B, it indicates that the target device is not within the range of the target area, and at this time, it can be determined that the target device is in an abnormal state.

[0075] Optionally, the alarming of the abnormal state can be alarming of the target device, the alarming of the abnormal state can be alarming of the target area, and the alarming of the abnormal state can also be alarming of the target device and the target area at the same time.

[0076] Optionally, the alarming of the target area can be directly performed by an alarm device of the target area, the alarming of the target area can be performed by a monitoring device, and the like.

[0077] Optionally, the target device can also be directly alarmed. The alarming of the target device can be performed at a target device end, the alarming of the target device can be performed at a monitoring device end, and the alarming of the target device can also be performed at the target device end and the monitoring device end at the same time.

[0078] Optionally, the alarming manner can be voice alarming, the alarming manner can be pop-up window alarming, the alarming manner can be short message alarming, the alarming manner can be alarm bell alarming, and the like.

[0079] For example, if the alarming manner is voice alarming, when device 1 is in an abnormal state, the monitoring device can issue an alarm voice: “device 1 is in an abnormal state, please handle in time”, and at the same time, the personnel identity information corresponding to device 1 can also be displayed on the display interface of the monitoring device. According to the obtained voice alarm signal and the displayed personnel identity information, the staff can quickly locate the irregular personnel.

[0080] Exemplarily, if the alarm mode is a pop-up alarm, when the device 2 is in the abnormal state, the monitoring device can issue a pop-up window: "Device 1 is in an abnormal state, the holder of device 1 is employee A, please handle it in time". The staff can quickly locate the irregular personnel according to the obtained pop-up alarm signal.

[0081] Optionally, when it is determined that the target device is in the abnormal state, the abnormal information that the device is in the abnormal state can be stored. The abnormal information can include target device ID, holder information corresponding to the target device, duration of the target device leaving the target area, and information of the area where the target device is located after leaving the target area.

[0082] Optionally, after storing the abnormal information, a violation record of the target device can be generated according to the abnormal information.

[0083] In a possible implementation, the device state monitoring method further includes: analyzing the positioning information of the target area to determine whether the target device is in a powered-on state; if the target device is in the powered-on state, determining that the target device is in the abnormal state; and when the target device is in the abnormal state, alarming the abnormal state.

[0084] Optionally, the above steps can be arranged after determining whether the target device leaves the target area. When it is determined that the target device is in the target area, it can be further determined whether the target device is in the powered-on state. If the target device is in the powered-on state in the target area, it can be further determined that the target device is in the abnormal state. If the target device leaves the target area, it is not necessary to further determine whether the target device is in the powered-on state.

[0085] In a possible implementation, the device state monitoring method further includes: filtering the state of the target device to obtain a first state of the target device; analyzing the first state of the target device to obtain target state information of the target device; and displaying the target state information and the unique identity information of the target device corresponding to the target state information in a report form.

[0086] Optionally, filtering the state of the target device can remove the state of the target device that is irrelevant to the target area.

[0087] Exemplarily, the state of the target device that is irrelevant to the target area can be a state that the target device leaves the target area at the end of work, a state that the target device is in the powered-on state at the end of work, a state that the target device is in an allowed area outside the target area, and the like.

[0088] The first state of the target device is a filtered state, and the first state is a state of the target device related to the target area within a set time period.

[0089] Exemplarily, the filtered target device state can be a state filtered from a state of the target device leaving the area within a set time period.

[0090] Optionally, the report can display the following contents: a target device on-off state, a target device in a target area, target device alarm data, target device area distribution, and target area distribution.

[0091] The embodiments of the present application calculate the position information of the target device according to the phase difference between the homing signal sent by the homing base station to the target device and the feedback signal sent by the target device according to the homing signal, and determine the state of the target device according to the position information of the target device and the range of the target area. When the target device is in an abnormal state, an alarm is sent in time to remind the staff to handle it. The whole process does not need to be intervened, and the automation of the target device monitoring is realized. Meanwhile, a report can be directly generated according to the positioning information and state information of the target device to display and count abnormal conditions, which reduces the workload of the staff, improves the work efficiency, and improves the monitoring accuracy.
