[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The street code safety monitoring method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The acquired temperature data and voltage data are stored in the data storage system. After the judgment of the cable operation status is completed, the judgment result and the street code information are sent to the server 104. After the server processes it, the terminal 102 reminds the operation and maintenance personnel to handle it. The judgment result and the street code information are also stored in the data storage system, and the data is uploaded to the cloud synchronously. Among them, the terminal 102 can be but not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0053] In the power system, in order to avoid public safety accidents caused by leakage, it is necessary to monitor and evaluate the operating status of cables at the street code. However, monitoring and evaluating the high temperature, leakage, short circuit and other faults of the cable requires the installation of monitoring equipment separately. However, there are many street codes, and the realization of the above monitoring and evaluation will bring about the problem of many equipments to be installed and high costs.

[0054] In one embodiment, Figure 2 As shown, a street code safety monitoring method is provided, and the method is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0055] Step 202, obtaining temperature data and voltage data of the cable at the street code, the voltage data including first voltage data and second voltage data; the first voltage data is the voltage data of the cable at the street code, and the second voltage data is the voltage data of the street code protective cover.

[0056] The cable is composed of metal fittings, iron bars and cable porcelain bottles nailed to the wall. The number of cable porcelain bottles determines the wiring method of the cable, including single-line cable and four-line cable. The cable protective cover is a device used to wrap the cable, usually made of soft injection molding material, which plays a role in protecting and insulating the cable.

[0057] Specifically, the server sets the time interval and frequency for acquiring cable data at the street code, and acquires temperature data and voltage data at the street code and voltage data of the street code protective cover according to the server settings. The server can also receive data acquisition instructions from the terminal and complete the data acquisition operation according to the instructions. Among them, the data acquisition instruction includes street code information, data acquisition time and acquisition content, etc. For example, street code information may include street code location information, street code wiring method, street code historical operation data, etc.; acquisition time may include data acquisition frequency, data acquisition duration, data acquisition start time, etc., and appointment acquisition may also be performed; acquisition content may be selected to acquire only voltage data, only temperature data, or all data at the street code cable. In addition, the first voltage of the cable at the street code and the second voltage of the street code protective cover may be acquired separately.

[0058] Step 204, judging the state of the cable at the street code according to the temperature data and the voltage data.

[0059] Specifically, the server stores a large amount of abnormal status data of Jiema cables, such as mechanical damage, insulation moisture, insulation aging and deterioration, overvoltage, material defects, protective cover corrosion, and insulation loss, etc. The server can model the cable fault data and cable abnormal status, and determine the cable status by acquiring the cable temperature data and voltage data.

[0060] Step 206, sending the determination result and the street code information to the backend server.

[0061] Specifically, the processed judgment results and street code information are sent to the background server and terminal, where the street code information includes street code location information, installation information, historical operation data, and historical maintenance data. By sending the street code location information to the background server, the operation and maintenance personnel can quickly locate the faulty street code location. The street code location information also includes the installation location environment information. Since different environmental information will affect the street code fault judgment, the operation and maintenance personnel can further judge the street code status based on the installation location environment information. The installation information includes the installation personnel information, installation time information, and street code installation model information; the historical operation data includes the street code operation time, street code fault time, and street code fault type; the historical maintenance data includes the historical maintenance personnel, historical maintenance time, and historical maintenance plan. The street code information is sent to the background server, and the operation and maintenance personnel make further judgments and confirmations on the judgment results through comprehensive information; they can also provide the operation and maintenance personnel with maintenance methods and safety precautions.

[0062] In the above-mentioned street code safety monitoring method, the temperature data and voltage data of the cable at the street code are respectively input into the server, and compared with the abnormal state data of the street code cable stored in the server to build a model, so as to judge the installation status of the cable at the street code. The faults of the cable at the street code have strong characteristics and regularity, and due to the large number of street codes installed and the poor working environment, it takes a lot of energy and financial resources to monitor them accurately. However, obtaining temperature data and voltage data can effectively reduce the cost and can realize comprehensive monitoring of the street code. The judgment results and street code information are sent to the background server, and the operation and maintenance personnel can make better analysis and judgment on the judgment results according to the street code information, and respond in time, thereby improving the accuracy of street code monitoring. It is also possible to refer to the maintenance methods and safety precautions provided to propose maintenance plans, which can better realize the interaction between operation and maintenance personnel and data. The operation and maintenance personnel can actively obtain data and set monitoring for any street code, which improves the flexibility of street code monitoring.

[0063] In one embodiment, Figure 3 FIG. 1 is a flow chart of the cable leakage judgment step. For example, judging the state of the cable at the street code according to the temperature data and the voltage data includes:

[0064] Step 302: Acquire a monitoring voltage difference according to the first voltage data and the second voltage data.

[0065] Step 304, judging the leakage state at the street code according to the monitored voltage difference and the voltage difference threshold; the voltage difference threshold is the maximum voltage difference at the street code for the cable to maintain no leakage.

[0066] Among them, the first voltage data is the voltage data of the cable at the street code, the second voltage data is the voltage data of the street code protective cover, the voltage difference refers to the potential difference or voltage difference between two points, and a higher voltage difference means a higher potential difference.

[0067] Specifically, since street codes are usually erected in densely populated areas such as streets, the insulation requirements for cables are relatively high. The cables should be insulated under the allowable voltage, that is, when the street code is in a safe operating state, there should be no voltage difference between the cable surface at the street code and the street code protective cover, or the voltage difference is within a safe range. The voltage data of the cable at the street code can be collected by selecting the voltage value on the cable surface, or the voltage value of the fixed line connected to the cable. The voltage data of the street code protective cover can be collected by selecting the voltage value of the inner wall of the street code protective cover, or the voltage value of other components set in the street code protective cover. Different voltage difference thresholds and voltage difference calculation methods are set according to different collected data. For example, the voltage value of the cable at the street code is calculated as a difference with the voltage value of the street code protective cover. After obtaining the voltage data, the obtained voltage difference is compared with the preset threshold value for judgment. When the voltage difference is lower than the preset threshold value, it is considered that the cable has no leakage and is in a safe operating state; when the voltage difference is higher than or equal to the preset threshold value, it is considered that the cable has leakage.

[0068] Furthermore, the comparison and judgment by voltage difference and preset threshold value can also be applied to conventional cables. Power cables and other functional cables, such as communication cables, coaxial cables, etc., often have abnormal situations such as accidental touch and entanglement, which in turn damage the insulation layer of the power cable and cause safety hazards such as leakage. The method of judging cable leakage by voltage difference can be used to monitor leakage at the intersection of cables. For example, the voltage value of the low-potential voltage sampling point and the voltage value at the cable are obtained at the cable, and the voltage difference is calculated. When the voltage difference is lower than the preset threshold, it is considered that the cable has no leakage and is in a safe operating state; when the voltage difference is higher than or equal to the preset threshold, it is considered that the cable has leakage.

[0069] In this embodiment, by comparing the monitored voltage difference with the voltage difference threshold, the monitored voltage difference is converted into an expression of the leakage condition, which reduces the difficulty of leakage monitoring, effectively avoids abnormal situations such as misjudgment and missed judgment, and improves the accuracy of judging cable leakage.

[0070] In another embodiment, step 204, judging the state of the cable at the street code according to the temperature data and the voltage data also includes: obtaining the monitoring temperature and the temperature change rate according to the temperature data; the temperature change rate is the temperature change of the cable per unit time; judging the temperature state of the cable at the street code according to the monitoring temperature and the temperature threshold; the temperature threshold is the maximum temperature at which the cable maintains safe operation; judging the short-circuit state of the cable at the street code according to the temperature change rate and the temperature change rate threshold; the temperature change rate threshold is the temperature change rate for maintaining safe operation.

[0071] Among them, the temperature change rate refers to the temperature change of the cable in unit time; the cable short circuit at the junction point refers to the short circuit that occurs when the conductive metal in the cable contacts the metal part of the junction point after the cable is damaged.

[0072] Specifically, by collecting the temperature data on the cable, analyzing and processing the temperature data, monitoring whether the cable has overload and heating problems. The temperature data includes temperature measurement time, measured temperature value, and temperature measurement times. The state of the cable is determined by the set temperature threshold and measured temperature value. When the metal of the cable contacts the street code, the voltage value on the street code will exceed 24V, and the device determines that the street code is leaking. For example, when the measured temperature of the cable exceeds the preset temperature threshold, a high temperature warning signal is generated; when the measured temperature of the cable is lower than the preset temperature threshold, the cable is in a safe operating state, and the temperature threshold can be set according to actual needs. Different temperature limits, such as 80℃ or 90℃. Different temperature thresholds can also set more diverse warning signals. For example, when the temperature threshold is 80℃, a cable overload warning is issued, and when the temperature is 200℃, an insulation layer melting warning is issued.

[0073] Furthermore, by integrating the temperature measurement time and the measured temperature value, the temperature change rate can be obtained, and the short circuit state of the cable can be judged according to the temperature change rate. It is also possible to predict the short circuit of the cable according to the temperature change rate in multiple heating intervals and the change trend of the temperature change rate, so as to realize the early judgment of the short circuit fault.

[0074] In this embodiment, by acquiring temperature data, dual early warning of high temperature and short circuit is achieved, which reduces the components required for the monitoring system, reduces the cost of system construction, and at the same time increases the ways of utilizing temperature data and improves data utilization efficiency.

[0075] In one embodiment, Figure 4 As shown, judging the state of the cable at the street code according to the temperature data and the voltage data also includes:

[0076] Step 402, when the system meets the first characteristic, a leakage warning signal is generated; the first characteristic is that the monitored voltage difference exceeds the voltage difference threshold, the monitored temperature does not exceed the temperature threshold, and the temperature change rate does not exceed the temperature change rate threshold.

[0077] Step 404, when the second characteristic is met, a high temperature warning signal is generated; the second characteristic is that the monitored temperature exceeds the temperature threshold, the monitored voltage difference does not exceed the voltage difference threshold, and the temperature change rate does not exceed the temperature change rate threshold.

[0078] Step 406, when the third characteristic is met, a short circuit warning signal is generated; the third characteristic is that the temperature change rate exceeds the temperature change rate threshold, the monitored temperature does not exceed the temperature threshold, and the monitored voltage difference does not exceed the voltage difference threshold.

[0079] Specifically, after obtaining the temperature and voltage data of the cable at the street code, it is compared with the preset voltage difference threshold, temperature threshold and temperature change rate threshold to determine whether the cable is in a safe operating state, and then generate warning signals, including leakage warning, high temperature warning and short circuit warning. Different status information can also be obtained according to different threshold settings, for example, raising the temperature threshold to obtain a warning of the cable insulation layer fuse, and obtaining a short circuit warning according to the temperature change rate.

[0080] Furthermore, after the early warning signal is generated, it can be transmitted to the backend server for alarm, and the operation and maintenance personnel can confirm the status of the cable and perform maintenance; at the same time, an alarm device can be set on the monitoring device. For example, when the cable is in an unsafe operating state, the fault light is always on, or different light alarms are set for different alarm types, so that the line patrol staff can directly see the light and perform maintenance and repair in time. In addition, according to the actual situation, it can be set to only light up without backend alarm, only backend alarm without light up, or a combination of the two.

[0081] In this embodiment, the acquired temperature data, voltage data and preset threshold value can be judged at the same time, or the safe operation status can be judged separately, thereby improving the flexibility and diversity of fault judgment. This avoids the situation where other faults are not monitored after a fault occurs, thus ensuring the comprehensiveness of the system.

[0082] In one embodiment, as in step 206, sending the judgment result and the street code information to the background server includes: uploading the judgment result and the street code information to the cloud platform at the same time; the street code information includes street code address data, temperature data and voltage data.

[0083] Specifically, after the collected temperature data and voltage data are judged and processed, the sensor converts the real-time monitoring data into digital signals. The collected data is transmitted to the cloud platform through the network, which can be achieved through wired connection, wireless connection or mobile network. The specific transmission method depends on the application scenario and actual needs. The data can be transmitted to the cloud platform through the application programming interface (API) or protocol of the cloud service provider. When the data arrives at the cloud platform, it will be stored in the database or storage system in the cloud. The cloud platform provides data storage services, such as relational databases, non-relational databases, object storage, etc. Data storage can be structured, partitioned, compressed, etc. as needed. The cloud platform performs data processing and analysis, data cleaning, data aggregation, statistical analysis, machine learning algorithms, etc. on the uploaded data and stored data. Data processing and analysis can extract useful information from the data to support decision-making and optimization.

[0084] Furthermore, after receiving the judgment result, the terminal calls the cloud platform data. The cloud platform usually provides an application program interface, through which the terminal can query, obtain, update or delete data as needed. The data query and visualization tools provided by the cloud platform can view and analyze cable operation data and historical fault data through charts, reports, dashboards, etc., to help operation and maintenance personnel quickly understand the trends, correlations and abnormalities between cable faults and temperature data and voltage data. The cloud platform can pass data to the terminal in the form of a stream through real-time data streams, so as to obtain data updates in real time and trigger corresponding warning signals according to set rules or thresholds. For example, when a certain data reaches a preset threshold, it can trigger notifications, warnings or other operations, and the terminal can choose an appropriate method to call the data in the cloud platform according to its own needs.

[0085] In this embodiment, using the cloud platform for data upload and call can provide flexible, reliable, secure, and efficient data management and analysis capabilities, helping to better utilize and value data. At the same time, the cloud platform can also reduce costs and improve resource utilization. After the data is uploaded to the cloud platform, it will be backed up and redundantly stored to prevent data loss or damage.

[0086] In one embodiment, Figure 5 As shown, a street code safety monitoring method is provided, the method comprising the following steps:

[0087] Step 502, obtaining temperature data and voltage data of the cable at the street code, the voltage data including first voltage data and second voltage data; the first voltage data is the voltage data of the cable at the street code, and the second voltage data is the voltage data of the street code protective cover.

[0088] Step 504 , obtaining a monitoring voltage difference according to the first voltage data and the second voltage data.

[0089] Step 506, judging the leakage state at the street code according to the monitored voltage difference and the voltage difference threshold; the voltage difference threshold is the maximum voltage difference at the street code for the cable to maintain no leakage.

[0090] Step 508, obtaining the monitoring temperature and the temperature change rate according to the temperature data; the temperature change rate is the temperature change of the cable per unit time.

[0091] Step 510, determining the temperature state of the cable at the street code according to the monitored temperature and the temperature threshold; the temperature threshold is the maximum temperature at which the cable can maintain safe operation.

[0092] Step 512, judging the short circuit state of the cable at the street code according to the temperature change rate and the temperature change rate threshold; the temperature change rate threshold is the temperature change rate for maintaining safe operation.

[0093] Step 514, when the system meets the first characteristic, a leakage warning signal is generated; the first characteristic is that the monitored voltage difference exceeds the voltage difference threshold, the monitored temperature does not exceed the temperature threshold, and the temperature change rate does not exceed the temperature change rate threshold.

[0094] Step 516, when the second characteristic is met, a high temperature warning signal is generated; the second characteristic is that the monitored temperature exceeds the temperature threshold, the monitored voltage difference does not exceed the voltage difference threshold, and the temperature change rate does not exceed the temperature change rate threshold.

[0095] Step 518, when the third characteristic is met, a short circuit warning signal is generated; the third characteristic is that the temperature change rate exceeds the temperature change rate threshold, the monitored temperature does not exceed the temperature threshold, and the monitored voltage difference does not exceed the voltage difference threshold.

[0096] Step 520, sending the determination result and street code information to the backend server.

[0097] Step 522, upload the judgment result and the street code information to the cloud platform simultaneously; the street code information includes street code address data, temperature data and voltage data.

[0098] In this embodiment, by obtaining voltage data and temperature data, comparing them with the preset voltage difference threshold, temperature threshold and temperature change rate threshold, it is determined whether the cable is in a safe operation state, generating warning signals, including leakage warning, high temperature warning and short circuit warning, and sending the warning signal and street code information to the background server and cloud platform. Taking into account a variety of possible cable problems, a fast and accurate cable status monitoring and warning method is provided to ensure the safe operation of the cable.
