Description

Technical Field

[0001] The present invention relates to the field of corporate security monitoring, and more particularly, to a computer-based corporate security alarm system. Background Art

[0002] With the rapid development of science and technology, companies and factories in various industries have established smart office models. Generally, large companies and factories are places where people gather and are also key monitoring areas for safety protection. Among them, electricity safety has always been a common problem faced by all companies and factories. Moreover, due to the concentration of office spaces, high density of people and complex environmental factors, a small electricity crisis may spread rapidly and expand, causing huge economic losses to companies and society.

[0003] Various electrical equipment will be installed in the office working environment of enterprises and factories. The continuous operation of these electrical equipment will cause a lot of power problems, especially for enterprises that use photovoltaic power generation as their power source. The problem of grid voltage exceeding the range has always been one of the "culprits" that affect the normal power generation of photovoltaic systems, resulting in AC undervoltage and AC overvoltage. Under continuous operation, it is also easy to cause safety accidents such as fire. Therefore, in terms of the company's safety monitoring, power monitoring of electrical equipment is also an important part of warning. Based on this, the present invention performs power monitoring and warning on the company's electrical equipment.

[0004] The invention with patent number CN112417504B discloses a computer-based company security alarm system, including a data identification module, a data processing module, a feedback module, an alarm module and an intelligent device. By setting up the data identification module, people entering and leaving the company are identified, and the items carried by visitors when entering and leaving the company are compared, and the distinguished images are transmitted to the reception staff's intelligent device for verification, so that the company's property and items can be effectively monitored and protected, and timely feedback reminders are obtained. At the same time, the company's internal files are processed with permissions to ensure the security of the company's internal file information. This design involves the identification of company personnel and the protection of file information, but has never involved the company's electricity safety issues. Therefore, based on the above problems, the present invention prevents and controls the safety issues of the company's electrical equipment. Summary of the invention

[0005] In view of the problem of power distribution in the case of power equipment failure and power transmission problems in the prior art, the purpose of the present invention is to provide a computer-based company security alarm system to achieve safety protection and warnings for the company during the use of electricity.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A computer-based company security alarm system, the security alarm system is based on an Internet of Things intelligent platform, including an application layer, an identification layer and a processing layer:

[0008] The identification layer includes a fault elimination module, which is used to perform fault detection on whether the circuits of each electrical device are normal before the electrical device is officially powered on and used, and to perform preliminary fault detection before the electrical device is used;

[0009] The processing layer includes a first monitoring module and a second monitoring module. The first monitoring module is used for detecting each electrical equipment during normal power-on use, mainly to detect whether the current and voltage values ​​of each electrical equipment show insufficient power supply or power overload. The second monitoring module is used for overall power consumption detection of distribution areas at all levels during normal power-on, mainly to detect whether the overall current and voltage values ​​of distribution areas at all levels match the output power of the power supply.

[0010] Preferably, the application layer includes a classification module. According to the types of the company's power-consuming products, the classification module divides the power supply branches into a primary distribution area, a secondary distribution area, and a tertiary distribution area. The primary distribution area includes lighting equipment, air-conditioning equipment, and other power-consuming equipment with a weaker degree of relevance to work; the secondary distribution area includes elevator equipment, monitoring equipment, and power-consuming equipment with a general degree of relevance to work; and the tertiary distribution area includes computer equipment and power-consuming equipment with a higher degree of relevance to work.

[0011] Assume that the distribution area is X, i is the level number of the distribution area, and i = 1, 2, 3, then X i represents the i-level distribution area, assuming that the number of electrical equipment in the first-level distribution area is w, the number of electrical equipment in the second-level distribution area is e, the number of electrical equipment in the third-level distribution area is r, the number of electrical equipment is U, and h is the sorting number of the electrical equipment. Then X i U h Indicates the hth power-consuming equipment in the i-level distribution area;

[0012] Among them, the level of association is: weak < average < high;

[0013] Power distribution priority: first-level distribution area < second-level distribution area < third-level distribution area.

[0014] Preferably, the identification layer includes a front module, which is used for company power supply regulation and includes a power-on control unit, a power-on delay unit and a power-on cycle unit;

[0015] The power-on control unit is used to issue instructions to the power supply to power on and off the power-consuming device U, and the power-on delay unit is used to set the delay time from the power-on control unit issuing the instruction to the actual execution of powering on or off the power-consuming device;

[0016] The power transmission cycle unit is used to collect the number of power consumption cycles of the power supply to the power-consuming device, wherein each power consumption cycle is set to be the same as the delay time in the power transmission delay unit;

[0017] The delay time is set to T, g is set to represent the power cycle, each power cycle time is set to Y, and Y=T, then Yg represents the g-th power cycle time.

[0018] By dividing and labeling the distribution areas and each power-consuming equipment, it is convenient to select and process them according to the priority and importance of the distribution areas when power shortage or failure occurs at the same time, ensuring that each power-consuming equipment and power point is responded to quickly, reducing the time for data transmission and processing, and improving data processing efficiency and accuracy.

[0019] Preferably, the identification layer includes a fault elimination module, which is used to detect whether the circuit of the electrical equipment is normal before the electrical equipment is powered on. The fault elimination module includes a first instruction unit, a first power identification unit and a first output unit. The detection process is specifically as follows:

[0020] S1. The first instruction unit sends a power-on signal P to the power-on control unit. After receiving the signal P, the power-on control unit starts the power supply and the power supply delay unit. The power supply supplies power to the power-consuming equipment U in the primary power distribution area, the secondary power distribution area and the tertiary power distribution area respectively. The power supply delay unit delays the arrival of the power supplied by the power supply to the power-consuming equipment, and the power supply time of the power supply is one power consumption cycle time Y. After one power consumption cycle time, the power supply is turned off and the power supply to the power-consuming equipment stops;

[0021] S2. By switching the power supply within a power cycle time Y, the electrical equipment is instantly powered on. During this power cycle time Y, the current identification unit performs real-time current and voltage detection on the power connection of each electrical equipment, and transmits the detection results to the first output unit;

[0022] S3. If during the detection process, the current and voltage values ​​detected in real time by each electrical device U are within the normal range, indicating that all electrical devices can be powered normally, the first output unit outputs all connected circuits to the processing layer;

[0023] If the current and voltage values ​​detected in real time by each electrical device U are within the abnormal range during the detection process, the current identification unit will locate and mark the abnormal electrical device U, and then turn off the abnormal electrical device U and exclude it from the power-on circuit. The first output unit will output the normal connection circuit after the abnormal electrical device is removed to the processing layer.

[0024] In addition, the first output unit sends the marked position of the abnormal electrical equipment U to the management personnel, who repair the faulty equipment. After the repair is successful, steps S1, S2 and S3 are repeated to re-detect the fault of the electrical equipment circuit.

[0025] Preferably, the processing layer includes a first monitoring module, which is used for local detection of each electrical device during normal power-on, mainly for whether the current and voltage values ​​of each electrical device are insufficient or overloaded. The first monitoring module includes a first analysis unit, a second power identification unit and a second output unit, and the specific process is as follows:

[0026] The specific working process of the second electric energy identification unit is as follows:

[0027] S1. Obtain the real-time power consumption value D of each power-consuming device in the first-level distribution area, the second-level distribution area, and the third-level distribution area, and then obtain the real-time power consumption value of the hth power-consuming device in the i-level distribution area And obtain the real-time attenuation value S of the circuit connected to each power consumption equipment in the first-level distribution area, the second-level distribution area and the third-level distribution area, and then obtain the real-time attenuation value of the circuit connected to the hth power consumption equipment in the i-level distribution area

[0028] Preferably, the specific working process of the analysis unit is:

[0029] S2. According to the formula

[0030]

[0031] Obtain the actual power transmission value of each power-consuming device

[0032] Among them, α is the real-time attenuation value The weight coefficient, β is the real-time power consumption value The weight coefficient is: A is the correction coefficient;

[0033] S3. The actual power transmission value of each power-consuming device Rated power transmission value Compare and then determine whether each electrical device has insufficient power supply or power overload. The specific process is: according to the formula

[0034]

[0035] Determine the value of the first determination value Sc;

[0036] Among them, η and μ are decision symbols.

[0037] By using the real-time power consumption value With real-time attenuation value Perform joint analysis to obtain the actual power transmission value received by each device from the power source The actual power transmission value of each electrical equipment Rated power transmission value A comparison is made to generate two judgment results. When the electrical equipment encounters abnormal conditions such as insufficient power supply or power overload, an alarm safety process is performed. When the electrical equipment is powered on and there is no abnormality, a normal use signal is output, thereby achieving accurate identification and precise positioning of abnormalities in the entire power line, improving maintenance efficiency and rapid response of personnel.

[0038] Preferably, the specific working process of the second output unit is:

[0039] S4. If Sc = η, it means the actual power transmission value Greater or less than the rated power transmission value When the electrical equipment has an abnormal situation of insufficient power supply or overload, it is determined that there is a potential safety hazard in the electrical equipment, and the second output unit outputs a warning signal of the abnormality of the electrical equipment;

[0040] If Sc=μ, it means the actual power transmission value Equal to the rated power transmission value The power consumption of the electric device is normal, and it is determined that there is no abnormality in the power-on of the electric device. The second output unit outputs a signal that the electric device can be used normally.

[0041] Preferably, the processing layer includes a second monitoring module, which is used for overall power consumption detection of the primary distribution area, the secondary distribution area and the tertiary distribution area during normal power-on, mainly for whether the current and voltage values ​​of the primary distribution area, the secondary distribution area and the tertiary distribution area are insufficient or overloaded. The second monitoring module includes a second analysis unit, and the specific process is as follows:

[0042] S1. Obtain the overall electric energy value ZX of each distribution area in the first-level distribution area, the second-level distribution area and the third-level distribution area. The specific acquisition process is as follows: According to the formula

[0043]

[0044] Then we can get the overall electric energy value ZX of the i-level distribution area: i ;

[0045] Among them, in the first-level distribution area, 1≤h≤w is set, in the second-level distribution area, 1≤h≤e is set, and in the third-level distribution area, 1≤h≤r is set;

[0046] S2. Obtain the power consumption value YD of all electrical equipment after aggregation in each distribution area. The specific acquisition process is as follows: According to the formula

[0047]

[0048] Then the power consumption of all electrical equipment in the entire company can be obtained.

[0049] Preferably, the second monitoring module includes a third output unit, which is used to compare the power consumption value YD of all electrical equipment in the entire company with the safe power transmission value JN of the power supply to determine whether the company has insufficient power supply or power overload. The specific process is as follows:

[0050] If the power consumption value YD>JN, it means that the power consumption value YD of all power-consuming equipment exceeds the safe power transmission value JN of the power supply. It is determined that there is a safety hazard in the power supply equipment, and an alarm signal is sent to the management personnel, who then check the abnormal power consumption;

[0051] If the power consumption value YD is less than JN, it means that the power consumption value YD of all power-consuming equipment is less than the safe power transmission value JN of the power supply, that is, the power supply of the power supply is insufficient. It is determined that there is a safety hazard in the power-consuming equipment, and an alarm signal is sent to the management personnel, or the power-consuming equipment in the distribution areas at all levels are selectively cut off, and the power-off priority of the distribution areas is the first-level distribution area> the second-level distribution area> the third-level distribution area, or the power supply of the power supply is increased;

[0052] If the power consumption value YD = JN, it means that the power consumption value YD of all electrical equipment is equal to the safe power transmission value JN of the power supply, that is, the company's power supply is normal and a safety signal is sent to the management personnel.

[0053] By comparing the power consumption value YD of all electrical equipment in the entire company with the safe power transmission value JN of the power supply, it is determined whether the company has insufficient power supply or power overload. This facilitates the selection of power on and off of power supply areas in the first-level distribution area, second-level distribution area and third-level distribution area when there is insufficient power or other conditions, so as to ensure the normal operation of the company to the greatest extent.

[0054] Preferably, the application layer includes an environmental protection module, which includes an air dust content monitoring unit and an environmental fire monitoring unit; the air dust content monitoring unit is used to prevent explosions caused by line short circuits, and to monitor the dust concentration in the company's internal power consumption areas in real time and push it to the administrator; the environmental fire monitoring is used to monitor the fire situation in the company's internal power consumption areas in real time and push it to the administrator.

[0055] Compared with the prior art, the present invention has the following beneficial effects:

[0056] 1. In the present invention, by dividing and labeling the distribution areas and each power-consuming equipment, the power-consuming equipment is graded according to the distribution areas, so that when power shortage or failure occurs at the same time, importance selection is carried out according to the priority and importance of the distribution areas. At the same time, when problems and failures occur, each power-consuming equipment and power point is responded to quickly, reducing the time for data transmission and processing, preventing recognition errors from occurring when failures occur at multiple power points, reducing data response errors caused by the simultaneous operation of a large amount of data, and improving data processing efficiency and accuracy.

[0057] 2. In the present invention, the real-time power consumption value of each electrical device is The current and voltage values ​​received by each electrical device during power-on are obtained by calculating the real-time attenuation value of each electrical device. The energy consumed by each electrical device during power transmission is obtained, and the real-time energy consumption value is converted into With real-time attenuation value Perform joint analysis to obtain the actual power transmission value received by each device from the power source The actual power transmission value of each electrical equipment Rated power transmission value A comparison is made to generate two judgment results. When the electrical equipment has an abnormal situation of insufficient power supply or power overload, an alarm safety process is performed. When the electrical equipment is powered on without abnormalities, a normal use signal is output. By real-time monitoring of whether the current and voltage values ​​of each electrical equipment show insufficient power supply or power overload during normal power-on use, accurate identification and precise positioning of abnormalities in the entire power line can be achieved, thereby improving maintenance efficiency and rapid response of personnel.

[0058] 3. In the invention, by comparing the power consumption value YD of all electrical equipment in the entire company with the safe power transmission value JN of the power supply, it is determined whether the company has insufficient power supply or power overload, so that it is convenient for the first-level distribution area, the second-level distribution area and the third-level distribution area to selectively power on and off the power supply areas in the distribution area when there is insufficient power or other conditions, so as to realize real-time detection of the company's overall power consumption, and maximize the guarantee of normal operation of the company under the interference of insufficient power and other factors.

Under continuous operation, it is also easy to cause safety accidents such as fire. Therefore, in terms of safety monitoring of the company, power monitoring of electrical equipment is also an important part of warning.

[0063] In the present invention, after each power outage, some equipment is affected by environmental factors or human interference and other special circumstances, and power transmission problems occur at the power connections or power lines.
