[0038] In order to make the person skilled in the art better understand the present scheme, the technical solutions in the embodiments of the present scheme will be clearly described below in combination with the drawings in the embodiments of the present scheme. Obviously, the described embodiments are only some of the embodiments of the present scheme, not all. Based on the embodiments in the present scheme, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present scheme.

[0039] The term "comprising" and other any variations thereof in the specification and claims of the present scheme and the above-mentioned drawings means "including but not limited to", which is intended to cover non-exclusive inclusion and is not limited to the examples listed in the text. In addition, the terms "first" and "second" and the like are used to distinguish different objects, not to describe a specific order.

[0040] The implementation of the present disclosure will be described in detail below in combination with specific drawings:

[0041] Figure 1 is a structural schematic diagram of a scenic spot monitoring system provided by an embodiment of the present disclosure. Referring to Figure 1 , the scenic spot monitoring system comprises a personnel detection module 10, an environment detection module 11, a subtraction module 12, a signal processing module 13, a lock delay module 14, a delay trigger module 15, an output module 16 and an alarm module 17;

[0042] The output end of the personnel detection module 10 is connected with the first input end of the subtraction module 12;

[0043] The output end of the environment detection module 11 is connected with the second input end of the subtraction module 12;

[0044] The output end of the subtraction module 12 is connected with the input end of the signal processing module 13;

[0045] The lock delay control end of the signal processing module 13 is connected with the lock delay module 14, and the output end of the signal processing module 13 is connected with the input end of the delay trigger module 15;

[0046] The output end of the delay trigger module 15 is connected with the input end of the output module 16;

[0047] The output end of the output module 16 is connected with the alarm module 17.

[0048] In the embodiment, the personnel detection module 10 and the environment detection module 11 are both pyroelectric infrared sensors. The personnel detection module 10 can be installed in the area close to the boundary of the scenic spot, and the detection area is the area close to the edge of the scenic spot, i.e. the area inside the scenic spot. When a person appears in the area, the alarm should be performed. The environment detection module 11 can be installed in the area far from the boundary of the scenic spot, and the detection area is the area far from the edge of the scenic spot, i.e. the area outside the scenic spot. The purpose is to eliminate the change of infrared heat source caused by environmental temperature and other factors. In the embodiment, a reference sensor is installed in the environment close to the pyroelectric infrared sensor. The reference sensor (i.e. the environment detection module 11) is used to monitor the change of infrared radiation of the environment background, and the measurement sensor (i.e. the personnel detection module 10) is used to monitor the change of infrared radiation of the human body and the change of the environment background. The signals collected by the measurement sensor and the reference sensor are subtracted to eliminate the interference caused by the change of the environment background, so that the information of the infrared line of the person can be obtained more accurately.

[0049] The output of the subtraction module 12 is the information of whether a person appears at the edge of the scenic spot, which is embodied as a change signal of voltage, and is an analog signal. Since the signal is weak and contains noise, it cannot directly drive the subsequent circuit, so the signal processing module 13 can be used for filtering and amplification processing.

[0050] The lock delay module 14 contains a lock unit and a delay unit. The lock unit is configured to stop the signal output of the signal processing module 13 within the preset time of the lock unit, so as to save the electric energy. The delay unit is configured to prolong the duration of the signal output, for example, the duration of the signal output is 10 seconds.

[0051] The delay trigger module 15 is configured to receive a high-level signal and further delay, so as to prolong the duration of the signal output. The output module 16 is configured to output a high-level signal to control the alarm module 17 to alarm. The alarm module 17 is configured to perform sound alarm.

[0052] From the above, the present disclosure can be concluded that the personnel detection module 10 detects personnel activities, the environment detection module 11 monitors external environmental changes, the subtraction module 12 eliminates the interference caused by the change of the environmental background through the subtraction operation, and outputs clear personnel activity signals. The infrared radiation changes caused by personnel activities and external environmental factors can be distinguished, so as to eliminate environmental interference and improve the accuracy of personnel detection. The false positive and false negative phenomena are reduced, the signal processing module 13 further filters and amplifies the signal, ensures the signal quality, and provides reliable input for the subsequent circuit. The locking time and the delay time preset by the locking delay module 14 improve the anti-interference ability of the present disclosure, and save the electric energy.

[0053] Figure 2 is a structural schematic diagram of a second scenic spot monitoring system provided by an embodiment of the present disclosure. Referring to Figure 2 In an embodiment of the present disclosure, the signal processing module 13 comprises a pyroelectric processing chip U6, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistor R8, a capacitor C1, a capacitor C2, a capacitor C3 and a capacitor C6.

[0054] The first in-phase input end of the pyroelectric processing chip U6 is connected with the output end of the subtraction module 12; the first anti-phase input end of the pyroelectric processing chip U6 is connected with the first end of the resistor R8, the first end of the resistor R7 and the first end of the capacitor C2 respectively, and the first output end of the pyroelectric processing chip U6 is connected with the second end of the resistor R7, the second end of the capacitor C2 and the negative electrode of the capacitor C6 respectively; the second end of the resistor R8 is grounded through the capacitor C3.

[0055] The positive electrode of the capacitor C6 is connected with the second anti-phase input end of the pyroelectric processing chip U6 through the resistor R6, and the second output end of the pyroelectric processing chip U6 is connected with the second anti-phase input end of the pyroelectric processing chip U6 through the capacitor C1; the first end of the resistor R5 is connected with the second output end of the pyroelectric processing chip U6, and the second end of the resistor R5 is connected with the second anti-phase input end of the pyroelectric processing chip U6; the bias current setting end of the pyroelectric processing chip U6 is grounded through the resistor R4.

[0056] The signal output end of the pyroelectric processing chip U6 is connected with the input end of the delay trigger module 15.

[0057] The locking delay module 14 comprises a resistor R9, a resistor R10, a capacitor C4 and a capacitor C5.

[0058] The first locking time adjusting end of the pyroelectric processing chip U6 is connected with the first end of the capacitor C4 through the resistor R9; the second locking time adjusting end of the pyroelectric processing chip U6 is grounded through the capacitor C4.

[0059] The first delay time adjustment end of the pyroelectric processing chip U6 is connected to the first end of the capacitor C5 through the resistor R10; and the second delay time adjustment end of the pyroelectric processing chip U6 is connected to the ground through the capacitor C5.

[0060] In the embodiment, the model of the pyroelectric processing chip U6 can be BISS0001, the personnel detection module 10 can be a pyroelectric infrared sensor U1, the environment detection module 11 can be a pyroelectric infrared sensor U2, and the signal output by the subtraction module 12 is first input to the first non-inverting input end of the pyroelectric processing chip U6, is amplified for the first time by the pyroelectric processing chip U6, is output from the first signal output end of the pyroelectric processing chip U6, and is input to the first inverting input end for the second time after being filtered and coupled by the capacitor C6 and the resistor R6.

[0061] The locking unit includes the resistor R9 and the capacitor C4, and the locking time of the locking unit can be adjusted by adjusting the resistance value of the resistor R9; and the delay unit includes the resistor R10 and the capacitor C5, and the preset time of the delay unit can be adjusted by adjusting the resistance value of the resistor R10.

[0062] For example, if it is desired that the subsequent alarm module 17 continuously outputs for 1 minute, the delay time can be set by adjusting the resistance value of the resistor R10, and the locking time can be adjusted by adjusting the resistance value of the resistor R9, thereby improving the anti-interference ability of the present disclosure, and the object will not be triggered again within the locking time when the object repeatedly moves.

[0063] When the personnel appear at the edge of the scenic spot, the analog signal is input to the pyroelectric processing chip U6 after being processed by the personnel detection module 10, the environment detection module 11 and the subtraction module 12, and is output as a high level after being processed by the pyroelectric processing chip U6, so as to control the subsequent module.

[0064] As can be seen from the above, the present disclosure can efficiently process the weak and noise-containing analog signal output by the subtraction module 12 by adopting the pyroelectric processing chip U6, the signal coupling is performed by the capacitor C6 and the resistor R6, the signal quality is improved, the locking delay module 14 is combined by the resistor R9, the resistor R10, the capacitor C4 and the capacitor C5, and the present disclosure is provided with flexible locking time and delay time adjustment functions, so that the locking time and the delay time can be adjusted according to actual needs, so as to adapt to the monitoring needs in different scenes.

[0065] Figure 2 is a structural schematic diagram of a second scenic spot monitoring system provided by the embodiment of the present disclosure. Referring to Figure 2In an embodiment of the present disclosure, the delay trigger module 15 comprises: a resistor R11, a transistor Q1, a transistor Q2, a voltage stabilizing tube VS1, a resistor R12, a resistor R13, a resistor R14, a resistor R19, a capacitor C7 and a capacitor C8.

[0066] The first end of the resistor R11 is the input end of the delay trigger module 15, the second end of the resistor R11 is connected with the base of the transistor Q1, the collector of the transistor Q1 is connected with the cathode of the voltage stabilizing tube VS1, the emitter of the transistor Q1 is grounded through the resistor R13, and the base of the transistor Q1 is grounded through the resistor R12.

[0067] The positive pole of the capacitor C8 is connected with the base of the transistor Q2 through the resistor R14, the negative pole of the capacitor C8 is connected with the anode of the voltage stabilizing tube VS1, and the negative pole of the capacitor C8 is grounded.

[0068] The collector of the transistor Q2 is connected with the collector of the transistor Q1 through the resistor R19, and the emitter of the transistor Q2 is grounded through the capacitor C7.

[0069] In an embodiment of the present disclosure, the output module 16 comprises: a unijunction transistor V1, a resistor R15, a resistor R17, a resistor R18 and a thyristor T1.

[0070] The emitter of the unijunction transistor V1 is connected with the emitter of the transistor Q2, the first base of the unijunction transistor V1 is connected with the first end of the resistor R18 through the resistor R15, the second base of the unijunction transistor V1 is grounded through the resistor R17, and the second base of the unijunction transistor V1 is connected with the control electrode of the thyristor T1.

[0071] The anode of the thyristor T1 is connected with the second end of the resistor R18, and the anode of the thyristor T1 is the output end of the output module 16; the cathode of the thyristor T1 is grounded.

[0072] In an embodiment of the present disclosure, the alarm module 17 comprises: a buzzer U5.

[0073] In the embodiment, the transistor Q1 and the transistor Q2 are NPN type transistors, when the input of the delay trigger module 15 is low, since the base of the transistor Q1 is low, the transistor Q1 is in the cut-off state, since the cut-off of the transistor Q1 causes the base of the transistor Q2 to also be low, the transistor Q2 is also in the cut-off state, thereby causing the oscillation circuit of the unijunction transistor V1 to be disconnected, causing the unijunction transistor V1 to also be in the cut-off state, the control electrode of the thyristor T1 cannot obtain a trigger voltage, at this time, the thyristor T1 is also in the cut-off state, and at this time, the buzzer U5 is not working.

[0074] When the input is high, that is, a person appears, the base of the transistor Q1 is high at this time, the transistor Q1 is turned on, the AC power supply U7 charges the capacitor C8 through the rectifier bridge U4 after the power supply voltage through the transistor Q1, (since the thyristor T1 is still in the off state at this time, the buzzer U5 has no power supply circuit, so the buzzer does not work at this time) even if the person does not move or the person leaves this area at this time, since the capacitor C8 has been charged, the base of the transistor Q2 is still high, the transistor Q2 is turned on at this time, the oscillation circuit composed of the resistor R19, the capacitor C7 and the unijunction transistor V1 starts to oscillate, due to the oscillation of the oscillation circuit, the control electrode of the thyristor T1 generates a trigger voltage, at this time the thyristor T1 is turned on, the buzzer U5 starts to work, and can emit a preset sound or audio to achieve the purpose of alarm.

[0075] And due to the departure of the person, the electrical energy stored in the capacitor C8 will be slowly released through the resistor R13, so the base voltage of the transistor Q2 will gradually change from on to off state, at this time the transistor Q2 can be regarded as a resistor with increasing resistance, at this time the oscillation frequency of the oscillation circuit changes, and then the conduction angle of the thyristor T1 changes, the sound of the buzzer will change from strong to weak, until there is no sound, and the thyristor T1 reverts to the off state.

[0076] From the above, it can be concluded that the embodiment realizes the delay alarm mechanism after personnel detection through the delay trigger module 15. When personnel are detected, the capacitor C8 is charged, even if the personnel do not move or leave afterwards, the transistor Q2 can still be turned on to make the oscillation circuit oscillate, and then trigger the alarm, thereby avoiding frequent alarms caused by temporary passing or instantaneous action of the personnel, and improving the effectiveness and stability of the alarm. After the personnel leave, the electrical energy stored in the capacitor C8 is slowly released through the resistor R13, the base voltage of the transistor Q2 gradually changes, the oscillation frequency of the oscillation circuit changes, the conduction angle of the thyristor T1 changes, the sound of the buzzer changes from strong to weak, and finally stops, thereby ensuring the low power consumption and stable operation of the present disclosure.

[0077] Figure 3 is a structural schematic diagram of a third scenic area monitoring system provided by the present disclosure. Referring to Figure 3 In an embodiment of the present disclosure, a scenic area monitoring system further comprises a control module 18, a first switch 19, a monitoring module 20 and a power supply module 21.

[0078] The first end of the first switch 19 is connected with the power supply end of the power supply module 21, the second end of the first switch 19 is connected with the monitoring module 20, and the control end of the first switch 19 is connected with the control signal output end of the control module 18.

[0079] The input end of the control module 18 is connected with the output end of the output module 16.

[0080] In one embodiment of the present disclosure, the scenic spot monitoring system further comprises a storage module 22.

[0081] The storage module 22 is connected with the monitoring module 20.

[0082] In the present embodiment, the first switch 19 is a normally open switch, when the output module 16 outputs a high level, the control module 18 controls the first switch 19 to close, at this time the power module 21 supplies power to the monitoring module 20, and the storage module 22 stores the image information monitored by the monitoring module 20, that is, when the edge of the scenic spot appears a person, the video recording and retention are performed, due to the delay of the lock delay module 14 and the delay trigger module 15, the monitoring module 20 can monitor more video information, under the premise of ensuring energy saving, the completeness of the monitoring video is improved.

[0083] From the above, it can be concluded that, through the first switch 19 and the control module 18, only when the output module 16 detects that a person appears at the edge of the scenic spot, the control module 18 controls the first switch 19 to close, so that the power module 21 supplies power to the monitoring module 20, avoiding the monitoring module 20 to work continuously for a long time without meaning, effectively reducing the system energy consumption, while ensuring the monitoring demand of the scenic spot, realizing the energy saving purpose. Through the delay function of the lock delay module 14 and the delay trigger module 15, after the person appears at the edge of the scenic spot to trigger the monitoring, the monitoring module 20 can work for a period of time, so that the monitoring module 20 can capture more video information related to the event, not only the moment when the person appears, but also the situation within a period of time after the person appears, thereby improving the completeness of the monitoring video.

[0084] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
