Description

Technical Field

[0001] The present invention relates to the technical field of security equipment used by judicial departments, and in particular to an intelligent multifunctional monitoring system. Background Art

[0002] In the judicial field, security monitoring of special areas where more than two people are detained is typically carried out through the installation of surveillance equipment and manual patrols to prevent unusual physical contact between individuals. This is done to minimize the risk of serious personal injury accidents caused by unusual physical contact within these areas. Monitoring unusual physical contact through surveillance equipment not only negatively impacts the privacy of individuals involved, but also, when management personnel are absent from the monitors in the duty room for various reasons or lack a high level of responsibility, there is a risk that unusual physical contact between two or more individuals may not be detected promptly by on-duty personnel, negatively impacting effective monitoring. Manual patrols not only inconvenience and increase labor intensity for patrol officers, but are also time-limited. This creates a high risk of unusual physical contact occurring during periods when patrol officers are not on duty, similarly negatively impacting effective monitoring.

[0003] With the development of science and technology, there are also existing systems based on artificial intelligence technology that monitor abnormal physical contact between two or more people in a relevant area. These systems mainly monitor the distance between two people, and when the distance is close enough, trigger a threshold, and then generate an alarm message. However, this method has a major technical flaw. That is, when normal interactions between people standing and entering the monitoring area (for example, when two people approach to shake hands or talk normally), or when two people sit side by side in the monitoring area, it is easy to cause false alarms, causing unnecessary interference to management personnel. In addition, the monitoring of abnormal physical contact between two or more people is only carried out through video monitoring software analysis. As a result, if the monitoring end fails or the software system encounters problems due to various reasons, it cannot effectively monitor abnormal physical contact. In other words, the existing technology based on a single method to monitor abnormal physical contact between two or more people in a specific area is extremely unreliable. When a single monitoring system fails (and there is only one way to prompt after abnormal physical contact is detected), relevant personnel cannot receive timely notifications and stop the abnormal physical contact between two or more people on the scene, which may cause serious personal injury accidents or even cause casualties to the people involved in the abnormal physical contact. Based on the above, it is particularly necessary to provide a system that can monitor abnormal physical contact behavior of people in relevant areas in multiple ways, ensure that the monitoring is real and effective, and prevent false alarms. Summary of the Invention

[0004] In order to overcome the drawbacks of the existing equipment or manual inspections for monitoring abnormal contact behavior of people in relevant areas due to technical limitations as described in the background, the present invention provides an intelligent multifunctional monitoring system that can monitor abnormal physical contact behavior of people in relevant areas in a variety of ways under the joint action of relevant circuits, structures and software units, and can prompt relevant people in a variety of ways when abnormal physical contact behavior occurs between two or more people, so as to prevent a single monitoring method from being unable to effectively monitor abnormal physical contact behavior, and a single prompting method from preventing relevant people from effectively receiving abnormal physical contact behavior data, and can more accurately judge abnormal physical contact behavior, thereby preventing misjudgment as much as possible, and thus providing favorable technical support for intelligent safety management of the corresponding area.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An intelligent multifunctional monitoring system includes a camera, a thermal imaging thermometer, and a power module installed in a cell, and is characterized in that it also has a detection mechanism, a control circuit, an alarm prompt circuit, a wireless receiving circuit, a data acquisition unit, a data analysis unit, a database unit, an alarm unit, and a gait judgment unit; the signal output ends of the camera and the thermal imaging thermometer are connected to the data input ends of the main control system in the prison duty room via data cables, and the data acquisition unit, the data analysis unit, the database unit, the alarm unit, and the gait judgment unit are application software installed in the main control system; the detection mechanism and the control circuit each have multiple identical sets, each set of the detection mechanism includes two photoelectric switches, and the two photoelectric switches of the multiple detection mechanisms are respectively installed on one side of the wall in the prison room, and the distance between the two photoelectric switches of each detection mechanism is greater than that of a single person. The width of the body of the prisoner standing up is not less than the width of two people standing up; the power module, control circuit, and alarm prompt circuit are installed in the electric control box, and the wireless receiving circuit is installed in the prison duty room; the signal output end of each detection mechanism is electrically connected to the signal input end of each control circuit, and the power supply of multiple control circuits is electrically connected to the power input end of the alarm prompt circuit; the data acquisition unit can collect image data in the corresponding area obtained by the camera, and can collect temperature change data in the corresponding area detected by the thermal imaging thermometer, and the data is classified and preliminarily analyzed and then output to the data analysis unit; after receiving the data output by the data acquisition unit, the data receiving unit will check the data in the database for comparison, and can alarm through the alarm unit when red substance appears on the floor of the cell, or when the temperature changes due to injury and bleeding of personnel, or when the personnel walk too fast.

[0007] Furthermore, among the multiple sets of detection mechanisms, the two photoelectric switches of two adjacent sets of detection mechanisms are close to each other.

[0008] Furthermore, each set of control circuits includes electrically connected relays, time relay modules, counters, and diodes. The negative power input terminals of the three relays are connected to the negative power input terminal of the counter, the negative power input terminal of the time relay module, and the negative control power input terminal. The positive power input terminals of the two relays are respectively connected to the positive poles of the two diodes, and the negative poles of the two diodes are connected to the positive trigger signal input terminal of the time relay module. The positive power output terminal of the time relay module is connected to the positive power input terminal of the third relay. The control contact terminal and the normally open contact terminal of the third relay are respectively connected to the two contacts under the reset button of the counter. The control contact terminal of the first relay is connected to one of the contacts of the cumulative counting key of the counter, and the other contact of the cumulative counting key is connected to the control contact terminal of the second relay. The normally open contact terminal of the second relay is connected to the normally open contact terminal of the first relay, and the positive power input terminal of the counter is connected to the positive power input terminal of the time relay module.

[0009] Furthermore, in each set of detection mechanisms, two ends of power input of the two photoelectric switches are electrically connected respectively.

[0010] Furthermore, the alarm prompt circuit includes an electrically connected wireless transmission circuit module and a text message module, an NPN transistor, and a resistor. The wireless transmission circuit module and the positive power input end of the text message module and one end of the resistor are connected. The wireless transmission circuit module and the negative power input end of the text message module and the emitter of the NPN transistor are connected. The other end of the resistor is connected to the base of the NPN transistor. The collector of the NPN transistor is connected to the trigger signal input end of the text message module. The two contacts under the first wireless transmission button of the wireless transmission circuit module are connected.

[0011] Furthermore, the wireless receiving circuit includes an electrically connected voltage stabilizing module and a resistor, an NPN transistor, a buzzer, and a wireless receiving circuit module; the positive power input end of the wireless receiving circuit module is connected to the positive power output end of the power module and the positive power input end of the buzzer; the negative power input end of the wireless receiving circuit module is connected to the base of the NPN transistor; the output end of the wireless receiving circuit module is connected to one end of the resistor; the other end of the resistor is connected to the base of the NPN transistor; and the collector of the NPN transistor is connected to the negative power input end of the buzzer.

[0012] Furthermore, the database unit stores a number of photo data in the cell. When a red substance appears at a corresponding point in the cell or the temperature and surrounding area rise abnormally, the data analysis unit determines that there is abnormal physical contact between two or more people and bleeding occurs.

[0013] Furthermore, the main control system also has an authority unit application software. When there is no abnormal physical contact between two or more people in the cell, the duty room will control the display screen not to display the image inside the cell. Only when it is determined that there is abnormal physical contact between two or more people in the cell will the display screen be controlled to display the image inside the cell, thereby protecting the privacy of relevant personnel.

[0014] The beneficial effects of the present invention are as follows: when two or more people have abnormal physical contact and repeatedly pass by the detection heads of two photoelectric switches in a corresponding time period, the wireless transmission circuit module and the text message module will be powered on and work, respectively alerting relevant management personnel through an on-site buzzer alarm and a text message alarm to indicate that there is abnormal physical contact in the corresponding area; if someone blocks the two photoelectric switches, but the time is short or the number of back-and-forth blocking is small, it is judged as a normal situation (such as when two people are in normal contact, approaching to shake hands or talking, or when two people are sitting side by side in the monitoring area), thus effectively preventing false alarms. Through the functions of the camera, thermal imaging thermometer, data acquisition unit, data analysis unit, database unit, and alarm unit, when someone has abnormal physical contact, bleeding, or walking too fast, the management personnel on duty at the display screen can be promptly notified. Through the above, the present invention can prompt relevant personnel in multiple ways when abnormal physical contact occurs in the corresponding area, preventing a single monitoring method from failing to effectively monitor abnormal physical contact behavior, and preventing relevant personnel from failing to effectively receive data on abnormal physical contact behavior using a single prompt method. It can also more accurately judge abnormal physical contact behavior, preventing misjudgment as much as possible, and thus providing favorable technical support for intelligent security management of relevant areas by relevant departments (such as judicial departments). Based on the above, the present invention has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

Each control circuit includes relays K1, K, K2, a time relay module A5, a counter A3, diodes VD, VD1 connected via circuit board wiring, the negative power input terminals of the three relays K1, K, K2, and the negative power input terminal 2 of the counter A3, the negative power input terminal 2 of the time relay module A5, and the negative trigger power input terminal 4. The positive power input terminals of the two relays K1 and K are respectively connected to the positive poles of the two diodes VD and VD1, and the negative poles of the two diodes VD and VD1 are connected to the positive trigger signal input terminal 3 of the time relay module A5. The time relay The positive power output terminal 9 of the detector module A5 is connected to the positive power input terminal of the third relay K2. The control contact terminal and the normally open contact terminal of the third relay K2 are respectively connected to the two contacts under the reset button Q of the counter A3. The control contact terminal of the first relay K1 is connected to one of the contacts of the cumulative count button J of the counter A3. The other contact of the cumulative count button J is connected to the control contact terminal of the second relay K. The normally open contact terminal of the second relay K is connected to the normally open contact terminal of the first relay K1. The positive power input terminal 1 of the counter A3 is connected to the positive power input terminal 1 of the time relay module A5. In each detection mechanism, the power input terminals 1 and 2 of the two photoelectric switches A2 and A are connected via wires. The alarm prompt circuit includes a wireless transmission circuit module A4 and a text message module A6, an NPN transistor Q1, and a resistor R1 connected through circuit board wiring. The positive power input terminal 1 pin of the wireless transmission circuit module A4 and the text message module A6 is connected to one end of the resistor R1, the negative power input terminal 2 pin of the wireless transmission circuit module A4 and the text message module A6 is connected to the emitter of the NPN transistor Q1, the other end of the resistor R1 is connected to the base of the NPN transistor Q1, the collector of the NPN transistor Q1 is connected to the trigger signal input terminal 3 pin of the text message module A6, and the two contacts under the first wireless transmission button S1 of the wireless transmission circuit module A4 are connected.

[0020] Figure 1 、 2As shown in Figures 3 and 4, the wireless receiving circuit includes a voltage regulator module A7 and a resistor R2, an NPN transistor Q2, a buzzer B, and a wireless receiving circuit module A8 connected via circuit board wiring. Pin 1 of the positive power input terminal of the wireless receiving circuit module A8 is connected to pin 3 of the positive power output terminal of the voltage regulator module A7 and the positive power input terminal of the buzzer B. Pin 3 of the negative power input terminal of the wireless receiving circuit module A8 is connected to the base of the NPN transistor Q2. Pin 4 of the output terminal of the wireless receiving circuit module A8 (pins 2, 5, 6, and 7 are left floating) is connected to one end of the resistor R2. The other end of the resistor R2 is connected to the base of the NPN transistor Q2. The collector of the NPN transistor Q2 is connected to the negative power input terminal of the buzzer B.

[0021] Figure 1 、 2 As shown in Figures 3 and 4, power input pins 1 and 2 of power module A1 are connected to the two poles of the AC 220V power supply via wires. Power output pins 3 and 4 of power module A1 are connected to pins 1 and 2 of photoelectric switches A2, the power inputs of multiple detection mechanisms, and pins 1 and 2 of counter A3, the power inputs of multiple control circuits, via wires. Pin 3 of photoelectric switches A2 and A, the first signal output of each detection mechanism, is connected to the positive power input of relays K1 and K, the signal inputs of each control circuit, via wires. The cathodes of diodes VD and VD1 are connected to pin 3 of time relay module A5 via wires. Pins 3 and 2 of counter A3, the signal output of multiple control circuits, are connected to pins 1 and 2 of wireless transmitter module A4, the power input of the alarm circuit, via wires. The data acquisition unit collects image data from the corresponding area captured by the camera and temperature change data from the corresponding area detected by the thermal imaging thermometer. After categorizing and analyzing the data, it outputs it to the data analysis unit. Upon receiving the data output by the data acquisition unit, the data analysis unit compares it with the data in the database unit. If a red substance appears on the floor of the cell, if the temperature changes due to injury or bleeding, or if someone in the corresponding area is walking too fast, the alarm unit can issue an on-site alarm via text or voice on the display screen. The database unit stores data from a number of photographs of the cell. If a red substance appears at a specific point in the corresponding area, or if the temperature and surrounding temperature rise abnormally, the data analysis unit determines that someone is bleeding due to abnormal physical contact with another person.

[0022] Figure 1 、 2As shown in Figures 3 and 4, after 220V AC power enters the power input of power module A1, pins 3 and 4 of power module A1 output a stable 12V DC power supply to the power inputs of multiple detection mechanisms and multiple control circuits, energizing these circuits. After 220V AC power enters the power input of voltage regulator module A7, pins 3 and 4 of voltage regulator module A7 output a stable 12V DC power supply to the power input of the wireless receiver circuit module, energizing wireless receiver circuit module A8. In the present invention, a camera can capture image data in a corresponding area in real time (when there is no abnormal physical contact between two or more people in the corresponding area, the permission unit application software in the duty room main control system will control the display screen to not display the image in the corresponding area. Only when it is determined that abnormal physical contact between people in the corresponding area occurs will the display screen be controlled to display the image in the corresponding monitored area, thereby protecting the privacy of relevant personnel). The thermal imaging thermometer can collect temperature change data in the corresponding area under thermal imaging conditions in real time. Both types of data are collected by a data acquisition unit, which classifies and preliminarily analyzes the collected image data in the corresponding area and the temperature change data in the cell and outputs them to a data analysis unit. After receiving the data output by the data acquisition unit, the data receiving unit will retrieve the data in the database for comparison. If a red substance appears on the floor of the cell (representing bleeding), if the temperature changes due to injury and bleeding, or if the pace is too fast (representing abnormal physical contact between people and others resulting in too fast pace), the alarm unit can issue an on-site alarm via text or voice alarm on the display screen. In this way, the duty personnel can rush to the cell site in time to take appropriate measures.

[0023] Figure 1 、 2As shown in Figures 3 and 4, in the present invention, when there is no abnormal human contact, the three pins of the two photoelectric switches A and A2 of the corresponding detection mechanism are unobstructed and do not output a high level. Thus, relays K1 and K are not energized, and the two contacts under the count key J of counter A3 are not closed, and counter A3 does not accumulate counts. When there is abnormal human contact, because the distance between the two photoelectric switches A and A2 of the corresponding detection mechanism is greater than the width of a single person standing and less than the width of two people standing in abnormal contact, when two people are in abnormal contact, the three pins of the two photoelectric switches A2 and A2, due to being blocked, will output a high level to the positive power input terminals of relays K1 and K. Relays K1 and K are energized, closing their control contact terminals and normally open contact terminals. This closes the two contacts under the count key J of counter A3 through the control contact terminal and normally open contact terminal of relay K1 and the control contact terminal and normally open contact terminal of relay K. Consequently, the two contacts under the count key J are connected, and counter A3 accumulates counts once. If no one makes abnormal physical contact, neither relay K1 nor relay K1 energizes, causing the two contacts under counter key J to close. Consequently, counter A3 will not increment. As described above, if a person makes abnormal physical contact in front of the corresponding set of two photoelectric switches A2 and A's detection heads, counter A3 will increment. If two people move out of the way of the corresponding set of photoelectric switches A2 and A's detection heads, pins 3 of the two photoelectric switches A2 and A no longer output a high level, and relays K1 and K again lose power and no longer close, counter A3's count key J will no longer close. When the two people's bodies are in abnormal contact and push each other and pass by the corresponding set of photoelectric switches A2 and A's detection heads again, the front end of the photoelectric switches A2 and A's detection heads of this set of detection mechanisms will output a high level again because pin 3 is blocked again, and the output will enter the positive power input terminal of relays K1 and K. Then relays K1 and K will be energized again and their control contact terminals and normally open contact terminals will be closed. In this way, the two contacts under the counting key J of counter A3 will form a path again through the control contact terminal and normally open contact terminal of relay K1 and the control contact terminal and normally open contact terminal of relay K. Then the two contacts under the counting key J will be connected again, and counter A3 will perform another cumulative counting. The above process is repeated continuously. When two people have abnormal physical contact and push and shove each other multiple times and pass by the photoelectric switch of the corresponding detection mechanism, the counter will accumulate the count multiple times (for example, 5 times, the number of times can be selected); when the count reaches the set number of the counter, pin 3 of counter A3 will output a high level and enter the power input terminal of wireless transmission circuit module A4 and SMS module A6. Then, wireless transmission circuit module A4 will emit the first wireless closing signal. The high level is limited and reduced by resistor R1 and enters the base of NPN transistor Q1. The collector of NPN transistor Q1 is turned on and outputs a low level and enters pin 3 of SMS module A6. Then, SMS module A6 sends a text message stored in it.In the present invention, when two people approach and talk at a close distance, under normal circumstances, the distance between the two people will not move back and forth multiple times past the photoelectric switches A2 and A detection heads of the corresponding set of detection mechanisms as in abnormal physical contact behavior. Therefore, the photoelectric switches A2 and A of the corresponding set of detection mechanisms can only be triggered a small number of times to output a high level. Then, the accumulated count of the counter will not reach the set number of the counter, and pin 3 of the counter A3 will not output a high level, and the subsequent wireless transmission circuit module and the text message module will not be powered and work.

[0024] Figure 1 、 2 As shown in Figure 3, during actual operation, every time someone passes by the photoelectric switch A2 and the detection head A of the corresponding set of detection mechanisms, the high level output by the photoelectric switch A2 and A will also be unidirectionally conducted through the diode VD or VD1 to enter the 3rd pin of the time relay module A5. Therefore, under the action of its internal circuit and the 9-pin output power time set by the technician, the time relay module A5 will output a certain time power to the positive power input terminal of the relay K2 at a certain interval (for example, the power is output for 2 seconds at an interval of 2 minutes). Therefore, at an interval of 2 minutes, the relay K2 is energized and closed for 2 seconds, and its control contact terminal and the normally open contact terminal are closed. In this way, the reset button of the counter A3 will be closed once for 2 seconds every 2 minutes, and the count of the counter A3 will be reset, so that the counter will be prepared for accumulating counts the next time someone passes by the photoelectric switch A2 and the detection head A. Through the combined effect of all the above circuits and mechanisms, when people in the corresponding area approach to communicate and talk normally, although they block the detection head of the photoelectric switch A2 and A of the corresponding detection mechanism, it is impossible for people to move their bodies away and approach frequently during normal communication and conversation, causing the photoelectric switches A2 and A3 pins to output high levels multiple times, and then the counter A3 outputs a high level after the set count number is reached. Therefore, the wireless transmission circuit module and the SMS module will not be powered on, thus preventing false alarms.

[0025] Figure 1 、 2As shown in Figure 3, when there is abnormal physical contact between two or more people in the corresponding area, SMS module A6 sends a text message. After receiving the text message, relevant personnel at any location can immediately know that there is abnormal physical contact in the corresponding area, and relevant personnel can rush to the scene to deal with it immediately. Wireless transmitting circuit module A4 transmits the first wireless closed signal. After receiving it, wireless receiving circuit module A8 will output a high level at its 4th pin, which is limited by resistor R2 and then reduced in voltage to the base of NPN transistor Q2. NPN transistor Q2 is turned on and the collector outputs a low level to the negative power input terminal of buzzer B. Buzzer B emits a loud warning sound, reminding the personnel in the duty room that there is abnormal physical contact in the cell and to deal with it in time. This prevents the personnel in the duty room from not carrying a mobile phone or not establishing a connection with the SMS module (such as network failure) from not receiving the abnormal physical contact signal. Through the combined action of all the above-mentioned mechanisms and circuits, when someone makes abnormal physical contact and passes repeatedly before the detection heads of the corresponding two photoelectric switches in a corresponding time period, the wireless transmission circuit and the SMS module of the present invention will be powered on and work, and respectively use a buzzer to give an on-site alarm and a text message to alert the relevant management personnel that someone has made abnormal physical contact in the corresponding area; if someone blocks the two photoelectric switches, but for a short time or the number of back-and-forth blocking is not large, it is judged as a normal situation (such as when two people are interacting normally and approaching to shake hands or talk), which effectively prevents false alarms; through the functions of the camera, thermal imaging thermometer, data acquisition unit, data analysis unit, database unit, and alarm unit, when bleeding occurs due to abnormal physical contact, the management personnel on duty at the display screen can be promptly alerted; the present invention can alert the relevant personnel in multiple ways when abnormal physical contact occurs between two or more people in the corresponding area, preventing a single monitoring method from failing to effectively monitor abnormal physical contact behavior, and preventing relevant personnel from failing to effectively receive abnormal physical contact behavior data due to a single prompting method, and can more accurately judge the abnormal physical contact behavior of people, thereby preventing misjudgment as much as possible.

After a low-level signal is input to the signal input port 3 of the SMS alarm module, the SMS alarm module can send a text message. The time relay module A5 model is YYC-2S. The time relay module A5 has two power input terminals 1 and 2, two trigger signal input terminals 3 and 4, a setting button 5, an emergency stop button 6, a time plus button 7, a time minus button 8, and a normally open power output terminal 9. After the operator presses the setting button, he operates the time plus button and the time minus button respectively, and can set the normally open power output terminal at the required time period. Output positive power supply, after the set time period, the normally open power supply output end stops outputting power supply, the time is set, and each time the trigger power signal is input to the two trigger signal input ends, the time relay module performs the set time timing; counter A3 is a finished counter of model SD76, which has two power input ends and one power output end, and also has a reset button and a cumulative counting key, and multiple setting buttons.
