Description

Technical Field

[0001] The invention belongs to the field of online monitoring of power transmission lines, and in particular relates to an online evaluation method for equipment operating status. Background Art

[0002] With the progress of society and the development of science and technology, the power industry has also ushered in new developments, gradually transforming from previous human inspections to intelligent online detection. However, since intelligent detection is carried out by monitoring equipment taking pictures of the channel for inspection, and the monitoring equipment is on the pole tower, it is difficult to intuitively judge the stability of the monitoring equipment. If the monitoring equipment cannot work normally for a long time and cannot detect the problem equipment in time, it may pose a potential threat to the inspection.

[0003] Chinese patent document CN111639769A (202010455324.X) discloses a remote maintenance method, device and electronic device for monitoring equipment. When applying the above scheme, by obtaining the operating status of the monitoring equipment in the target area, and calculating the working status form corresponding to the operating status of the monitoring equipment, further obtaining the abnormal information of the monitoring equipment, matching the correlation coefficient between the operating status of the monitoring equipment and the abnormal information according to the working status form, comparing the correlation coefficient with the preset abnormal coefficient, obtaining the abnormal fault information table, and sending the abnormal fault information table to the server. In this way, when the monitoring equipment in the target area fails, the monitoring equipment in the target area can be promptly troubleshooted and maintained, and the troubleshooting results can be uploaded to the server, thus reducing maintenance costs and avoiding data loss. Although the above scheme provides a method for troubleshooting the operating status of the monitoring equipment, there is no specific description on how to obtain the operating status of the monitoring equipment, and it is impossible to intuitively judge whether the monitoring equipment can upload pictures normally and the factors affecting the stability of the equipment uploading pictures. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to address the problem that there is no intuitive reflection of the stability of the equipment, and to provide an online evaluation method for the operation status of an equipment. The present invention performs a series of evaluations on the battery voltage, battery power, signal strength, signal type, etc. of the equipment, and finally determines the factors affecting the stability of the equipment according to the designed threshold value and outputs the corresponding identification through the monitoring platform, which more intuitively reflects the factors affecting the stability of the equipment and improves the efficiency of troubleshooting the stability of the equipment.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: an online evaluation method for the operation status of a device, wherein the number of photos taken is set to N within a set time T, and the specific method is as follows:

[0006] Step S1: When within the set time T, the time difference of the device uploading pictures is less than or equal to the set time difference threshold and the difference between the number of pictures actually uploaded and the set number of photos is less than or equal to the picture difference threshold, the device stability is qualified, otherwise the monitoring platform outputs an unstable picture upload mark;

[0007] Step S2: When the monitoring platform outputs an unstable image upload mark, further check the online status of the monitoring device. If the device is not online, restart the device. If the device cannot be restarted, the stability of the device is unqualified, and the monitoring platform outputs a device failure mark.

[0008] If the device can be restarted, a capture instruction is issued to the monitoring device. If the device can upload pictures normally according to step S1, the device stability is qualified. Otherwise, an unstable device status indicator is output;

[0009] Step S3: When the monitoring platform outputs an unstable device status indicator, further check the device status to obtain the device's signal information and battery voltage and battery power information;

[0010] The signal information includes signal type and signal strength. When the signal strength under different signal types is less than the corresponding signal strength threshold, the monitoring platform outputs a signal unstable flag;

[0011] The battery voltage is compared with a set voltage threshold, and when the actual battery voltage is less than the set voltage threshold, the monitoring platform outputs a voltage instability mark;

[0012] The battery power is compared with a set power threshold, and when the actual battery power is less than the set power threshold, the monitoring platform outputs an unstable power indicator;

[0013] Among them, the unstable image upload mark, equipment failure mark, unstable equipment status mark, unstable signal mark, unstable voltage mark and unstable power mark are different. The influencing factors of equipment stability are determined according to different stability impact values, and then the next step of troubleshooting is carried out.

[0014] The technical solution of the present invention also includes that the unstable signal indicator includes a 2G unstable signal indicator, a 4G unstable signal indicator and a 5G unstable signal indicator, and the 2G unstable signal indicator, the 4G unstable signal indicator and the 5G unstable signal indicator are different.

[0015] The technical solution of the present invention is that the image upload instability mark, equipment failure mark, equipment status unstable mark, signal unstable mark, voltage unstable mark and power unstable mark are represented by different numbers or different letters.

[0016] The technical solution of the present invention also includes that in step S1, the time difference of uploading pictures by the device and the difference between the number of pictures actually uploaded and the set number of pictures taken are calculated using the following formula:

[0017] Where i = 1, 2, 3....Dn (1)

[0018] Nd=Pn-An (2)

[0019] In the formula, Td is the average time difference of uploading pictures by the device, unit / min; i is the order of taking pictures; Dn is the actual number of pictures; Pt is the time of taking pictures; At is the actual time of uploading pictures; Pn is the set number of pictures, unit / picture; An is the actual number of pictures uploaded, unit / picture; Nd is the difference between the set number of pictures and the actual number of pictures uploaded, unit / min, where the time of taking pictures and the actual time of uploading pictures are the standard time of the National Time Service Center, i.e. Beijing time.

[0020] The technical solution of the present invention also includes that in step S3, the battery voltage and battery power information are obtained through the MCU in the device battery box; and the signal information is obtained through the inserted SIM card and the interface provided by the operator.

[0021] The technical solution of the present invention also includes that in step S3, the signal type includes 2G, 4G and 5G, and the signal strength includes 0 to 5 grids.

[0022] Beneficial effects of the present invention: In order to check whether the function of the monitoring equipment to take pictures is stable and quickly check the factors that affect the stability of taking pictures, the present invention sets the number of pictures within the set time, uses the picture taking time and the actual upload time to calculate the actual number of pictures and the time difference of uploading pictures, checks whether the equipment delays or misses taking pictures, and when delayed or missed pictures occur, further checks the equipment online status, and when the equipment is online or after the equipment is restarted, the equipment signal, battery voltage, and battery power are further checked. In order to more intuitively and quickly check the factors that cause the equipment to take pictures unstably, by setting the signal strength threshold, voltage threshold, and power threshold, when the threshold requirements are not met, the corresponding identifiers are directly output on the monitoring platform, and equipment problems can be quickly identified.

[0023] When a device fails, there is no need to manually connect to the server to view the device's uploaded information. It can be directly checked through the output identifier on the monitoring platform.

[0024] It can also check the information of multiple devices at one time, which improves the efficiency of checking the working status of the equipment.

[0025] The inventive concept of the present invention is as follows: whether the device is stable mainly depends on whether it can upload pictures normally, and whether the uploaded pictures meet the requirements for line monitoring is determined based on the difference between the number of pictures actually uploaded and the set number of pictures uploaded and the time difference between uploading to the monitoring platform after taking the pictures. When the device can upload the set number of pictures within the specified time and there is no delay in uploading the pictures, it means that there is no problem with the device's photo function and the upload path. When the number of pictures taken does not meet the requirements or the pictures are uploaded with delay, it means that the transmission path is unstable.

[0026] The factors that affect the stability of image uploading are divided into four factors: device hardware, signal, battery voltage, and battery power; and these four factors may cause the device to go offline and fail to work normally; however, due to factors such as weather, the signal, battery voltage, and battery power are temporarily unstable. When image uploading is unstable, in order to check whether the device hardware is faulty, it is necessary to check the signal, battery voltage, and battery power one by one. In order to make the fault visible, by defining and outputting monitoring marks for the working conditions where the signal, battery voltage, and battery power cause device instability when there is no fault in the device hardware, the factors affecting device instability can be quickly identified, thereby improving the efficiency of equipment fault troubleshooting. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 The figure is a flow chart of the online evaluation method for the equipment operation status according to the present invention. DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation examples, but the present invention is not limited to the scope of the description of the implementation examples.

[0029] like Figure 1 As shown in the figure, an online evaluation method for the operation status of equipment is provided. Within the set time T, the number of photos is set to Pn. In the table, the above picture is the abbreviation of the uploaded picture. The specific method is as follows:

[0030] Step S1: When within the set time T, the time difference of the device uploading pictures is less than or equal to the set time difference threshold and the difference between the number of pictures actually uploaded and the set number of photos is less than or equal to the picture difference threshold, the device stability is qualified, otherwise the monitoring platform outputs the picture upload instability flag, and the picture upload instability flag is 60.

[0031] Uploading pictures is mainly to check whether there are any missing pictures or delayed picture uploads. If the delays and missing pictures are within a reasonable range, no processing is required. If there are long-term missing pictures and delayed picture uploads, it is necessary to check the voltage, power, and signal values. If there are any problems, a restart is required. If the restart cannot solve the problem, the equipment needs to be disassembled for repair.

[0032] The time difference of uploading pictures by the device and the difference between the actual number of uploaded pictures and the set number of photos are calculated using the following formula;

[0033] Where i = 1, 2, 3....Dn (1)

[0034] Nd=Pn-An (2)

[0035] In the formula, Td is the average time difference for the device to upload pictures, unit / min; i is the order of taking pictures; Dn is the actual number of pictures; Pt is the time of taking pictures; At is the actual time of uploading pictures; Pn is the number of set pictures, unit / picture; An is the actual number of pictures uploaded, unit / picture; Nd is the difference between the set number of pictures and the actual number of pictures uploaded, unit / min.

[0036] Step S2: When the monitoring platform outputs an unstable image upload mark, further check the online status of the monitoring device. If the device is not online, restart the device. If the device cannot be restarted, the stability of the device is unqualified, and the monitoring platform outputs a device failure mark. The device failure mark is 100.

[0037] The device is offline by counting whether pictures are uploaded on the same day. So when the device is offline, first check whether the photo time format of the device is set reasonably and correctly; if the photo time format does not meet the requirements, the device cannot recognize it and needs to be reset, and then check whether the device can upload pictures normally.

[0038] If the photo time format is set correctly, you need to check again whether the voltage, power and signal values ​​are correct. If they are correct, you need to restart the device by sending a text message. After the restart, send a snapshot command to determine whether the picture is uploaded normally.

[0039] If it still doesn't work properly, you need to wait for a day, because the device may be out of power and has not uploaded the latest battery information. You need to wait for the solar energy to charge the device. Test again. If it still doesn't work, it is scheduled as a hardware failure of the device, and the device needs to be disassembled and repaired.

[0040] If the device can be restarted, a capture instruction is issued to the monitoring device. If the device can upload pictures normally according to step S1, the device stability is qualified. Otherwise, an unstable device status indicator is output. The unstable device status indicator is 50.

[0041] Step S3: When the monitoring platform outputs an unstable device status indicator, further check the device status to obtain the device's signal information and battery voltage and battery power information. The battery voltage and battery power information are obtained through the MCU in the device battery box; the signal information is obtained through the inserted SIM card and the interface provided by the operator.

[0042] The signal information includes signal type and signal strength. The signal types include 2G, 4G and 5G, and the signal strength includes 0 to 5 grids. When the signal strength under different signal types is less than the corresponding signal strength threshold, the monitoring platform outputs a signal instability mark. The signal instability mark includes a 2G signal instability mark, a 4G signal instability mark and a 5G signal instability mark, and the 2G signal instability mark, the 4G signal instability mark and the 5G signal instability mark are different. Specifically, when the signal type is 2G and the signal strength is 1-3 grids, the 2G signal instability mark 15 is output; when the signal type is 4G and the signal strength is 1-3 grids, the 4G signal instability mark 10 is output; when the signal type is 5G and the signal strength is 1-3 grids, the 5G signal instability mark 5 is output. If the signal strength is less than 1 grid, the device will be offline. If it is greater than 3 grids, data can be transmitted stably.

[0043] The battery voltage is compared with the set voltage threshold. When the actual battery voltage is less than the set voltage threshold, the monitoring platform outputs a voltage instability mark. Specifically, the set voltage threshold is the rated voltage value, and the voltage instability mark is 40. Voltage instability will also affect the stability of uploading pictures on the device.

[0044] The battery power is compared with the set power threshold, and when the actual battery power is less than the set power threshold, the monitoring platform outputs an unstable power indicator. The unstable power indicator is 20. When the battery power is too low, it will cause instability in offline or uploading pictures.

[0045] Among them, the unstable image upload flag, equipment failure flag, unstable device status flag, unstable signal flag, unstable voltage flag and unstable power flag are different. The factors affecting the stability of the equipment are determined according to different stability impact values, and then the next step of investigation is carried out. The unstable image upload flag, equipment failure flag, unstable device status flag, unstable signal flag, unstable voltage flag and unstable power flag are represented by different numbers.

[0046] Application Examples

[0047] Step S1: There is a device of model X to calculate the stability of the device. The specific steps are as follows:

[0048] Find devices that have data transmission within one hour, calculate the average time difference between the device taking a photo and uploading the picture, Td = 3 minutes; count the total number of pictures uploaded by the device, 3300.

[0049] According to the device's start and end time of taking photos and the photo interval, the device should upload 3330 pictures.

[0050] The time difference between the device uploading pictures shall not exceed 5 minutes and the difference between the actual number of uploaded pictures and the set number of photos shall not exceed 10. The time difference between the device photo taking time and the upload time is Td = 3 minutes. The difference between the actual uploaded pictures and the pictures to be uploaded is Nd = Pn-An = 20, which is greater than 10. Since the difference between the actual uploaded pictures and the pictures to be uploaded does not meet the threshold requirement, there is a problem of missed photos, so the picture upload unstable flag 60 is output.

[0051] Step S2: obtaining the status of the device from being offline to being online.

[0052] Step S3: Set the battery voltage threshold of the device of model X to 9 V. Obtain the battery voltage value uploaded by the device as 9.1 V.

[0053] The signal type uploaded by the device is 4G; the signal strength is 3 bars, so the 4G signal unstable indicator 10 is output.

[0054] The battery voltage Vmax is obtained to be 9.1V, and the voltage threshold Vd is set to 9V, Vmax>Vd.

[0055] To sum up, it can be concluded that unstable signal is the reason for the unstable uploading of pictures by the device. The operation and maintenance personnel will conduct targeted troubleshooting based on the device number.

[0056] The specific troubleshooting process is as follows:

[0057] 1) When the voltage or power is unstable, you need to observe for a few days depending on the weather. If the device uploads pictures stably later, no processing is required. If the problem persists, you need to restart the device to see if there is still a problem. If the problem still exists, the device needs to be dismantled and repaired.

[0058] 2) When the signal value is unstable, if the operator is China Telecom, switch the China Telecom card to B3 or B5 band for inspection. Other operators also need to observe first, then restart, and if there is still a problem, dismantle the equipment for maintenance.
