Description

Technical Field

[0001] The present invention relates to the technical field of safety monitoring of unmanned cabins, and specifically to a safety monitoring and alarm system for unmanned cabins. Background Art

[0002] "Unmanned cabins" generally refer to buildings or facilities without permanent occupants, which may be used for various purposes, such as vacations, storage, offices, workshops, or other uses. Since there are no permanent occupants in these cabins, special safety and monitoring measures are required to protect their property and internal facilities;

[0003] Currently, the safety of unmanned cabins is usually ensured by installing surveillance cameras near their entrances and windows to monitor whether there are people entering or leaving the unmanned cabins, so as to ensure that the unmanned cabins are not illegally entered and the internal equipment or property is stolen. However, in the case of a planned intrusion, illegal intruders usually choose to disconnect the power supply of the surveillance to avoid being captured by the surveillance and leaving corresponding evidence. When the surveillance equipment of the unmanned cabin is powered off, it is impossible to timely give an early warning of the safety of the unmanned cabin and issue corresponding alarms, which will then result in the loss of property in the unmanned cabin. Summary of the Invention

When a power outage occurs, the power supply module powers the image acquisition module, and the image acquisition module collects image data at the entrance of the unmanned cabin, and analyzes and processes the acquired image data to judge whether the unmanned cabin has been invaded by criminals due to a power outage, and can timely issue an alarm, avoiding the situation where it is impossible to know whether the unmanned cabin has been illegally invaded after the surveillance equipment of the unmanned cabin is powered off, and avoiding the phenomenon of property loss in the unmanned cabin due to a power outage. At the same time, the real-time power volatility and incoming power quality of the unmanned cabin are also analyzed through the incoming current and voltage data, so that it is possible to timely know whether there is an abnormality in the power system of the unmanned cabin, so that when an abnormality occurs in the power system of the unmanned cabin, staff or managers can timely repair the power system of the unmanned cabin, improving the stability of the power system of the unmanned cabin, etc. The above problems are solved.

[0007] To achieve the above object, the present invention provides the following technical solution: A safety monitoring and alarm system for an unmanned cabin, comprising a power monitoring data acquisition module, a power monitoring data analysis module, an image acquisition module, a power supply module, and an early warning module;

[0008] The power supply monitoring data acquisition module consists of a current acquisition unit for the incoming circuit of the unmanned hut and a voltage acquisition unit for the incoming circuit of the unmanned hut. The current acquisition unit for the incoming circuit of the unmanned hut is used to acquire the real-time incoming current data Dl of the unmanned hut, and the voltage acquisition unit for the incoming circuit section of the unmanned hut is used to acquire the real-time incoming voltage data Dy of the unmanned hut. The power supply monitoring data set acquisition module sends the acquired real-time incoming voltage data Dy and real-time incoming current data Dl to the power supply monitoring data analysis module;

[0009] The power supply monitoring data analysis module forms an incoming voltage data set and a current data set for the incoming current data Dl and the real-time incoming voltage data Dy received according to the number of data collected per minute, and performs data cleaning on the data in these two data sets to obtain the cleaned value Dlq of the incoming current data and the cleaned value Dyq of the incoming voltage data. The power supply monitoring data analysis module calculates the real-time power volatility BD of the unmanned hut according to the calculated cleaned value Dlq of the incoming current data and the cleaned value Dyq of the incoming voltage data, and calculates the incoming power quality Zl according to the generated multiple cleaned values Dlq of the incoming current data. The power supply monitoring data analysis module compares the calculated real-time power volatility BD and the incoming power quality Zl with the corresponding thresholds to judge whether there are abnormalities in the real-time power fluctuation and the incoming power quality. When an abnormality occurs, an abnormal signal 1 or an abnormal signal 2 is generated and sent to the warning module;

[0010] When the power supply monitoring data analysis module receives that the real-time incoming voltage data Dy or the real-time incoming current data Dl is 0, the power supply monitoring data analysis module determines that the unmanned hut is powered off, generates a power-on signal, and sends it to the power supply module. After receiving the power-on signal, the power supply module starts to supply power to the image acquisition module. After receiving the power supply, the image acquisition module acquires the image data Tx at the entrance of the unmanned hut. The image acquisition module compares the acquired image data Tx with the preset original image data YT at the entrance of the unmanned hut inside it to judge whether the unmanned hut has been invaded, and sends an intrusion signal to the warning module;

[0011] When the warning module receives the abnormal signal 1 or the abnormal signal 2 or the intrusion signal, it issues a corresponding warning.

[0018] In the formula, denotes the sum of all data in the incoming household voltage dataset, denotes the average of the result of summing all data in the incoming household voltage dataset, and this average is the cleaned value Dyq of the voltage data.

[0019] Preferably, the calculation expression of the real-time power volatility BD is as follows:

[0020]

[0021] In the formula, Dlq * Dyq represents the product of the currently calculated cleaned value of the incoming household voltage data and the cleaned value of the incoming household current data, which is the incoming household power value. Dlq q *Dyq q represents the product of the previously calculated cleaned value of the incoming household current data adjacent to the currently calculated cleaned value of the incoming household current data and the previously calculated cleaned value of the incoming household voltage data adjacent to the currently calculated cleaned value of the incoming household voltage data, which is the previously calculated incoming household power value of the current incoming household power value. That is, it represents the growth rate of the incoming household power values calculated twice, which is the real-time power volatility BD.

[0022] Preferably, the calculation expression of the incoming household power quality Zl is:

[0023]

[0024] In the formula, n + 5 means that every 6 cleaned values of the incoming household current data form an incoming household current cleaning dataset. I = 2 means starting the calculation from the second data value in the incoming household current cleaning dataset, that is, starting from Dlq n+1 and calculating up to the (n + 5)-th data, that is, calculating up to Dlq n+5Up to this point, Dlj represents the fundamental wave of current, and this value is obtained according to the standard in the design of the unmanned hut circuit.

[0025] Preferably, when the real-time power volatility is greater than the power fluctuation threshold, it is determined that there is an abnormal fluctuation in the output power of the circuit, and the power supply monitoring data analysis module generates an abnormal signal one;

[0026] When the incoming power quality is less than the incoming power quality threshold, it is determined that the incoming power quality is abnormal, and the power supply monitoring data analysis module generates an abnormal signal two.

[0027] Preferably, the comparison expression of the image data Tx obtained by the image acquisition module and the image data YT of the original unmanned hut entrance preset inside it is as follows:

[0028] ΔTz = |Tx - YT|

[0029] In the formula, |Tx - YT| represents taking the absolute value of the difference between the currently obtained image data and the image data YT of the preset original unmanned hut entrance, and feeding back whether the currently obtained image data Tx has corresponding characteristic data more than the image data YT of the preset original unmanned hut entrance. ΔTz represents the result of the comparison between the obtained image data Tx and the image data YT of the original unmanned hut entrance preset inside it.

[0030] Preferably, the judgment process of the image acquisition module for judging whether the unmanned hut has been invaded is as follows:

[0031] When ΔTz < 10, the image acquisition module determines that the unmanned hut is not invaded at this time;

[0032] When ΔTz > 10, the image acquisition module determines that the unmanned hut is invaded at this time;

[0033] When the image acquisition module determines that the unmanned hut is invaded three times in a row, the image acquisition module generates an intrusion signal.

[0034] Preferably, when the warning module receives the abnormal signal one, the warning module issues a warning of abnormal power fluctuation in the unmanned hut circuit to the staff;

[0035] When the warning module receives the abnormal signal two, the warning module issues a warning of poor power quality in the unmanned hut to the staff;

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 It is a schematic diagram of the system flow of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1 , a security monitoring and alarm system for an unmanned hut, including a power supply monitoring data acquisition module, a power supply monitoring data analysis module, an image acquisition module, a power supply module, and an early warning module;

[0042] Among them, the power supply monitoring data acquisition module is composed of an incoming current acquisition unit at the incoming end of the unmanned hut circuit and an incoming voltage acquisition unit at the incoming end of the unmanned hut circuit. The incoming current acquisition unit at the incoming end of the unmanned hut circuit is used for the real-time incoming current data Dl of the unmanned hut. The power supply monitoring data acquisition module sends the acquired real-time incoming voltage data Dy and real-time incoming current data Dl to the power supply monitoring data analysis module;

[0043] The power supply monitoring data analysis module judges the received real-time household voltage data Dy and real-time household current data Dl. When the values of both the real-time household voltage data Dy and the real-time household current data Dl are greater than 0, the received real-time household voltage data Dy and real-time household current data Dl are respectively formed into a household voltage data set and a current data set according to the number of data collected per 1 minute. The expressions of these two data sets are as follows:

[0044] The expression of the household voltage data set is: {Dy1, Dy2,..., Dy n};

[0045] The expression of the household current data set is: {Dl1, Dl2,..., Dl n};

[0046] Among them, the number of data in these two data sets is the same, the time points of each data collection are the same, and the collection periods are the same.

[0047] After the power supply monitoring data analysis module forms the corresponding data sets, the data in these two data sets are respectively cleaned to obtain the cleaned value Dlq of the household current data and the cleaned value Dyq of the household voltage data. Their calculation expressions are as follows:

[0048] The calculation expression of the cleaned value Dlq of the household current data is as follows:

[0049]

[0050] In the formula, represents the sum of all data in the household current data set, represents the average value of the sum of all data in the household current data set, and this average value is the cleaned value Dlq of the current data;

[0051] The calculation expression of the cleaned value Dyq of the household voltage data is as follows:

[0052]

[0053] In the formula, represents the sum of all data in the household voltage data set, represents the average value of the sum of all data in the household voltage data set, and this average value is the cleaned value Dyq of the voltage data;

[0054] By cleaning the data in the two data sets, the corresponding more accurate voltage and current data values within a certain period of time can be obtained, which can improve the accuracy of subsequent calculations.

[0055] The power monitoring data analysis module calculates the real-time power fluctuation rate BD of the unmanned cabin according to the calculated household current data cleaning value Dlq and household voltage data cleaning value Dyq. The calculation expression is as follows:

[0056]

[0057] In the formula, Dlq*Dyq represents the product of the current calculated household voltage data cleaning value and the household current data cleaning value, which is the household power value. q *Dyq q The product of the last calculated household current data cleaning value adjacent to the currently calculated household current data cleaning value and the last calculated household voltage data cleaning value adjacent to the currently calculated household voltage data cleaning value is the household power value calculated last time before the current household power value. That is, it represents the increase rate of the household power value obtained by the two calculations, which is the real-time power fluctuation rate BD;

[0058] By calculating the real-time power fluctuation rate, it helps the managers or staff of the unmanned cabin to know whether the power system of the unmanned cabin is stable in real time, so that when an abnormality occurs, the possible problems of the power system can be repaired in time.

[0059] The household power quality Zl is calculated based on the generated multiple household current data cleaning values ​​Dlq. Before calculating the household power quality Zl, the multiple household current data cleaning values ​​Dlq are first combined into a household current cleaning data set, and the expression is: {Dlq n , Dlq n+1 , ..., Dlq n+5}, this data set consists of 6 data values, which is equivalent to the current data of the unmanned cabin for 1 hour.

[0060] The calculation expression of household power quality Zl is:

[0061]

[0062] In the formula, n+5 means that every 6 household current data cleaning values ​​form a household current cleaning data set, and I=2 means that the calculation starts from the second data value in the household current cleaning data set, that is, from Dlq n+1 Start calculating until the n+5th data, that is, until Dlq n+5 So far, Dlj represents the fundamental wave of current, and this value is obtained according to the standard when designing the circuit of the unmanned cabin.

[0063] By calculating the incoming power quality, it can assist the staff or management personnel of the unmanned cabin to grasp the incoming current fluctuation and harmonic interference of the unmanned cabin in real time, so as to master the quality of the incoming power in real time. When abnormal values always appear, the staff or management personnel can timely repair the power system of the unmanned cabin, thereby improving the stability of the power system of the unmanned cabin;

[0064] The power supply monitoring data analysis module compares the calculated real-time power volatility BD and the incoming power quality Zl with the corresponding thresholds to determine whether there are abnormalities in the real-time power fluctuation and the incoming power quality. The specific comparison is as follows:

[0065] When the real-time power volatility BD is greater than the power fluctuation threshold, it is determined that the output power of the circuit has an abnormal fluctuation, and the power supply monitoring data analysis module generates an abnormal signal one;

[0066] When the incoming power quality Zl is less than the incoming power quality threshold, it is determined that the incoming power quality is abnormal, and the power supply monitoring data analysis module generates an abnormal signal two;

[0067] The power supply monitoring data analysis module sends the generated abnormal signal one or abnormal signal two to the warning module.

[0068] When the warning module receives the abnormal signal one, the warning module issues a warning to the staff about the abnormal fluctuation of the circuit power of the unmanned cabin;

[0069] When the warning module receives the abnormal signal two, the warning module issues a warning to the staff about the poor power quality of the unmanned cabin.

[0070] When the power supply monitoring data analysis module receives that the real-time incoming voltage data Dy or the real-time incoming current data Dl is 0, at this time, it means that there is a power outage in the unmanned cabin, that is, a man-made power outage or a power outage for line maintenance. The power supply monitoring data analysis module determines that the unmanned cabin is powered off, generates a start power signal, and sends it to the power module. After receiving the start power signal, the power module starts to supply power to the image acquisition module. When the image acquisition module receives the power supply again, it immediately acquires the image data Tx of the entrance of the unmanned cabin. It should be noted that the image acquisition module is powered by the power module and the circuit system of the unmanned cabin. When the circuit system is powered off, the image acquisition module is turned off due to power failure, but after the power module starts to supply power, the image acquisition module receives the electric energy again and starts. At this time, it can be understood that the image acquisition module has experienced a rapid power outage and power supply situation. When the image acquisition module receives the power supply again, it immediately collects the image data of the entrance of the unmanned cabin. The image acquisition module compares the acquired image data Tx with the pre-set original image data YT of the entrance of the unmanned cabin. The specific expression of the comparison is as follows:

[0071] ΔTz = |Tx - YT|

[0072] In the formula, |Tx - YT| represents taking the absolute value of the difference obtained by subtracting the image data YT of the preset original entrance of the unmanned hut from the currently acquired image data Tx, and feeding back whether the currently acquired image data Tx has corresponding feature data more than the image data YT of the preset original entrance of the unmanned hut. ΔTz represents the result of comparing the acquired image data Tx with the image data YT of the preset original entrance of the unmanned hut inside it.

[0073] The judgment process for the image acquisition module to judge whether the unmanned hut has been invaded is as follows:

[0074] When ΔTz < 10, the image acquisition module determines that the unmanned hut is not invaded at this time;

[0075] When ΔTz > 10, the image acquisition module determines that the unmanned hut is invaded at this time;

[0076] When the image acquisition module determines that the unmanned hut is invaded three times in a row, the image acquisition module generates an intrusion signal;

[0077] The 10 mentioned above represents the allowable error of the acquired image data relative to the image data of the original entrance of the unmanned hut. When the unmanned hut is invaded three times in a row, it can prevent passers-by passing by the entrance of the unmanned hut from being misjudged and improve the accuracy of the judgment. The interval of image acquisition is the same and can be set according to the actual usage situation. For example, what is the time interval for a pedestrian to pass by the entrance of the unmanned hut normally.

[0078] When the warning module receives the intrusion signal, the warning module issues an alarm to the staff that the unmanned hut has been illegally invaded.

[0079] By collecting the data of the incoming current and voltage of the unmanned hut and judging whether there is a power outage in the unmanned hut according to the values of the incoming current and voltage. When there is a power outage, the power supply module supplies power to the image acquisition module. The image acquisition module collects the image data of the entrance of the unmanned hut and analyzes and processes the acquired image data to judge whether the unmanned hut has been invaded by criminals due to the power outage, and can issue an alarm in time to prevent the situation that the monitoring equipment of the unmanned hut cannot know whether the unmanned hut has been illegally invaded after the power outage and avoid the loss of property of the unmanned hut due to the power outage. At the same time, it also analyzes the real-time power volatility and incoming power quality of the unmanned hut through the analysis of the incoming current and voltage data, and can timely know whether there is an abnormality in the power system of the unmanned hut, so that when there is an abnormality in the power system of the unmanned hut, the staff or management personnel can repair the power system of the unmanned hut in time and improve the stability of the power system of the unmanned hut.

[0080] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
