Description
Technical Field
The invention relates to the field of scenic spot passenger flow monitoring, in particular to a regional passenger flow monitoring system and method based on video image analysis.
Background
The tourism industry is an important component of the modern service industry. In recent years, with the upgrading of consumption level and the adjustment of industrial structure, the willingness of people to travel and travel is continuously improved, the continuous development of scenic spots is promoted, the tourism industry is unprecedentedly developed, and the spirit civilization construction of China is brightly increased.
The scenic spot receives extensive attention of people and can provide people and economic support for better development of the scenic spot, but the passenger flow carrying capacity of the scenic spot needs to be considered while construction is carried out, particularly in holidays in the golden week, mid-autumn and other festivals, the number of visitors in the scenic spot is obviously more than that in weekdays, the scenic spot needs to monitor the passenger flow in the scenic spot in real time, potential safety hazards are eliminated as far as possible, and safety accidents are avoided.
The traditional passenger flow monitoring system mainly counts the passenger flow of a scenic spot or a scenic spot through passenger flow computing equipment such as a gate, a pressure sensor and a passenger flow counter which are arranged at the entrance and exit of the scenic spot, stops ticketing or prevents visitors from entering a crowded area when the passenger flow reaches an upper limit, and simultaneously sends out early warning to inform the visitors to leave rapidly. In addition, in the traditional monitoring system, cameras are further arranged at multiple positions in a scenic spot to acquire video image information, and the passenger flow density in the region is judged through image recognition and analysis methods such as deep learning, so that the safety risk caused by excessive passenger flow in local regions of the scenic spots although the number of people in some scenic spots does not reach the upper limit is eliminated.
However, when the passenger flow in the area is overloaded, the existing passenger flow monitoring system only prevents the passengers from entering the congested area to avoid the continuous increase of the passenger flow in the area, and the passenger flow in the area can be reduced to a normal range after a certain time, so that the passengers are easily bound in key areas such as shooting points in the area during the time period when the passenger flow is gradually reduced, and the local passenger flow density in the area still has a safety risk of being too high. Moreover, even if the passenger flow density at the shooting point is identified to be too high through image information acquisition, the tourists are informed to leave quickly only in a broadcasting alarm mode, and some tourists who do not comply with the instructions may continue to stay in the area for shooting and commenting, and the broadcasting alarm does not dissuade the tourists.
Disclosure of Invention
The invention aims to provide a regional passenger flow monitoring system and a method based on video image analysis.A current limiting device positioned on the water surface is arranged at a hot shot point in a karst cave scenic spot, when the passenger flow exceeds a threshold value, the current limiting device enters a prompting state and is switched between the prompting state and an alarming state along with the continuous change of the passenger flow on the current limiting device, and when the current limiting device is in the prompting state and the alarming state, the current limiting device generates vibration with a certain amplitude along the vertical direction, so that a tourist is prompted to leave after the tourist stays for a short time, the tourist is prevented from staying and taking pictures on the current limiting device, the tourist can leave the hot shot point as soon as possible, and the safety of the scenic spot is obviously improved.
The invention is realized by the following technical scheme:
the utility model provides a regional passenger flow monitoring system based on video image analysis, includes scenic spot monitoring platform and sight spot monitoring unit, its characterized in that:
the scenic spot monitoring platform is used for receiving the passenger flow information from the scenic spot monitoring units, comparing the passenger flow information with the passenger flow threshold of the corresponding scenic spot, sending an early warning signal to the corresponding scenic spot monitoring unit when the passenger flow information is greater than the passenger flow threshold, and sending a release signal to the corresponding scenic spot monitoring unit when the passenger flow information is reduced to be less than the passenger flow threshold;
the scenic spot monitoring unit is used for acquiring passenger flow information in a corresponding scenic spot, sending the passenger flow information to a scenic spot monitoring platform, controlling the current limiting devices in the scenic spot to be switched from a supporting state to a non-supporting state based on the early warning signal, and controlling the current limiting devices in the scenic spot to be switched from the non-supporting state to the supporting state based on the releasing signal;
in the unsupported state, the flow-limiting device produces vibrations in the vertical direction under the effect of buoyancy and/or elastic forces.
In the technical scheme, the scenic spot monitoring platform is located at the dispatching end, the scenic spot monitoring units are arranged at scenic spots to be monitored, one scenic spot to be monitored can be monitored by the same scenic spot monitoring unit, a plurality of scenic spots to be monitored can also be monitored simultaneously, and preferably, one scenic spot monitoring unit corresponds to one scenic spot to be monitored.
The scenic spot monitoring unit is used for acquiring passenger flow information in a corresponding scenic spot and sending the passenger flow information to a scenic spot monitoring platform at a dispatching end, the monitoring platform calls a passenger flow threshold of the scenic spot preset in the database, the passenger flow threshold is compared with the passenger flow information, when the passenger flow information is greater than the passenger flow threshold, the number of people in the current scenic spot is indicated to exceed a safety precaution line, and if tourists gather at hot shooting points or watching points in the scenic spot, potential safety hazards exist. Therefore, based on the comparison result, the scenic spot monitoring platform feeds back an early warning signal to the scenic spot monitoring unit to control the scenic spot monitoring unit to enter an early warning state. In the early warning state, along with the gradual reduction of the passenger flow, when the passenger flow information is smaller than the passenger flow threshold value, the scenic spot monitoring platform feeds back a release signal to the scenic spot monitoring unit to release the early warning state and restore to the normal state.
Under the early warning state, the scenic spot monitoring platform sends a state switching signal to the current limiting devices arranged at each position in the scenic spot, so that the supporting state of the current limiting devices is changed, and the current limiting devices are supported by the rigid support under the supporting state and are changed into buoyancy support and/or elastic support under the non-supporting state. In the unsupported state, the current limiting device on the water surface can move up and down under the action of buoyancy along with the movement of the tourists and the increase and decrease of the number of the tourists, so that the tourists are reminded that the number of the tourists in the current scenic spot exceeds a threshold value, and the current limiting device is a good shooting point but should leave as soon as possible. When the early warning state is released, the scenic spot monitoring platform sends a state switching signal to the current limiting devices arranged at each position in the scenic spot, so that the supporting state of the current limiting devices is changed into a supporting state from a non-supporting state, and in the supporting state, the current limiting devices are only supported by the rigid supporting function of the supporting devices and are not supported by buoyancy or elastic support any more, so that after the early warning state is released, tourists can stay on the current limiting devices for a long time without worrying about the problem that the tourists are too dense to flow.
The scenic spot that current-limiting device corresponds is the scenic spot that has the waters, and its shooting point is located waters bank or waters. In one or more embodiments, the scenic spot is a karst cave, the karst cave is a dark light environment, the guest needs a longer exposure time when taking a picture, and cannot shake during the exposure process so that the camera can take a clear picture, and when the current limiting device enters an unsupported state, the generated small vibration is enough to make the guest unable to take a clear picture when taking a picture, so that the shot point becomes an undesired or poor shot point, and the motivation of the guest to stay on the current limiting device disappears, so the guest gradually leaves away, and the crowd gathering at the shot point is eliminated.
The principle of this technical scheme does, under non-early warning state, because the head number in the sight spot is less, the difficult gathering of visitor or even there is not the potential safety hazard in the gathering yet, current limiting device is the rigid support this moment. After entering the early warning state, the passenger flow exceeding the safety early warning line enables the interior of the scenic spot to be more easily gathered, especially at the hot shooting point. Therefore, a current limiting device is provided at the hot spot, and the current limiting device vibrates up and down in the vertical direction as the passenger flow on the current limiting device changes, and the change of the vibration frequency and the amplitude indicates that the guest should not stay on the current limiting device. For the waters of dark scenic spots such as karst caves and the like, the tourists can be reminded through the change of frequency and amplitude, clear photos can be prevented from being shot by the tourists fundamentally, the motivation of the tourists staying on the current limiting device is eliminated, and the tourists are promoted to leave the current area.
It will be appreciated by those skilled in the art that the purpose of arranging the flow restriction means to vibrate with buoyancy and/or spring force is to indicate that the amplitude of the float plate of the flow restriction means should not be too large for safety reasons. In one or more embodiments, the amplitude of the floating plate can be limited to be not more than 1-2 cm by changing the volume, the area and the material of the floating plate of the current limiting device, so that the vibration frequency and the amplitude of the floating plate are far smaller than those of the cable bridge; in some embodiments, it is also safer with respect to the lateral swinging of the bridge by adding the constraint points of the guide posts so that the vibration direction can only move up and down in the vertical direction.
Compared with the prior art, after the scenic spot is judged to enter the early warning state, the supporting state of the current limiting device can be switched, the environment of a dark light water area in the scenic spot is combined, and the passenger flow on the current limiting device is utilized to enable the current limiting device to generate vertical vibration of amplitude within a safety range, so that a prompt effect is provided for tourists gathered on the current limiting device; in addition, the visitor is fundamentally prevented from taking a clear picture, and the motivation for the visitor to stay on the flow restriction device is eliminated, thereby effectively urging the visitor away from the current area.
Further, the scenic spot monitoring unit comprises a passenger flow volume acquisition module, and the passenger flow volume acquisition module is used for acquiring passenger flow volume information in the scenic spot.
Furthermore, the scenic spot monitoring unit further comprises an image processing module, an alarm module and a camera mounted on the current limiting device, wherein the camera is used for collecting image information of the tourists on the current limiting device and sending the image information of the tourists to the image processing module, the image processing module is used for processing the image information of the tourists, identifying the tourists in the image information of the tourists and sending an alarm signal to the alarm module, and the alarm module is used for giving an alarm according to the alarm signal.

In some embodiments, the image information may also be sent to a scenic spot monitoring platform or a scenic spot monitoring unit to visually display the video information collected by the camera in time and dynamically.
Furthermore, the alarm module is an alarm mounted on the current limiting device. The alarm can be used for carrying out non-specified early warning on passenger flow on the current limiting device, such as voice broadcasting, audible and visual alarming and the like, and can also be used for alarming to workers in a workshop, and the workers are allowed to report the current scenic spot state to the tourists so as to orderly guide the tourists on the current limiting device.
Further, the alarm module sends alarm information to the terminal of the tourist identified in the image information of the tourist. The tourist terminal can be a bracelet or a mobile phone, a tablet personal computer and other equipment, and the alarm information aims at carrying out appointed early warning on passenger flow on the current limiting device so as to prompt the tourist to leave the current limiting device as soon as possible.

Through setting up the spout to extending along vertical direction, can make the slider slide in vertical direction, and then drive and restraint the kickboard and only can reciprocate.
The length of the first supporting mechanism is adjustable. When the first supporting mechanism extends, the first supporting mechanism supports the floating plate, the floating plate is jacked to the upper part of the water surface, the current limiting device enters a supporting state, and at the moment, tourists can linger and take photos on the current limiting device at will. After the water surface enters the early warning state, the first supporting mechanism drags the floating plate to vertically move downwards, after the water surface is contacted, the first supporting mechanism continues to shrink to the position below the water surface, the water surface replaces the first supporting mechanism to provide buoyancy support for the floating plate, and the first supporting mechanism is not contacted with the floating plate at the moment. When the tourists move on the floating plate and increase or decrease the number of the tourists on the floating plate, the floating plate vibrates on the water surface under the combined action of the gravity and the buoyancy of the tourists and is limited by the guide columns, and the vibration only moves up and down along the vertical direction.

Under the alarm state, the vibration amplitude of the floating plate is increased, the lower stroke limit of the floating plate is contacted with and acts on the top end of the telescopic rod to push the telescopic rod to vertically move downwards towards the inside of the sleeve, partial pressure is removed while the spring is compressed, after the pressure is removed, the spring pushes the telescopic rod to vertically move upwards, and the telescopic rod acts on the lower surface of the floating plate. Therefore, the second supporting device limits the amplitude of the floating plate through the elastic supporting effect, when the downward amplitude is too large, the elastic supporting effect plays a role in buffering, the floating plate is prevented from being further downwards detected by combining increased buoyancy, the upper and lower amplitudes of the floating plate are limited in a safer range, and the safety and the stability of the current limiting device are improved.
Furthermore, a locking mechanism is arranged on the floating plate and comprises a locking state and an unlocking state, and the floating plate and the telescopic rod move synchronously in the locking state. And the locking mechanism arranged on the floating plate is used for locking or unlocking the connection between the floating plate and the telescopic rod. When kickboard and telescopic link pass through the locking mechanism lock, kickboard and telescopic link can reciprocate in step, and the spring turns into the spring to the elastic support effect of kickboard to the elastic action of telescopic link, not only prevents the too much to surface of water below removal of kickboard, plays when kickboard rebound to the surface of water and draws the effect of dragging, and then reduces the amplitude of kickboard remarkably, is favorable to the kickboard to reply stably fast, switches to the suggestion state from the state of reporting an emergency and asking for help or increased vigilance. After the state is switched, the locking mechanism is unlocked, the floating plate is separated from the telescopic rod, and the floating plate vibrates in a small amplitude range.
Further, the lower surface of kickboard is provided with the constant head tank, constant head tank and telescopic link one-to-one, the size phase-match of the size on the top of constant head tank and telescopic link. The constant head tank can show and reduce the telescopic link top produced lateral sliding when contacting with the kickboard, and then improves the life of kickboard and guide post, promotes current limiting device's stability and security.
As a preferred embodiment of the locking mechanism, the locking mechanism comprises a driving rod, the driving rod is movably inserted into the floating plate and can rotate around the axis of the driving rod, an accommodating cavity is arranged in the floating plate and is communicated with the positioning groove, a clamping piece is arranged in the accommodating cavity, one end of the clamping piece extends into the positioning groove, the lower surface of the part of the clamping piece, which is positioned in the positioning groove, is an inclined surface, and the other end of the clamping piece is connected to the driving rod through a second spring; the rotation of the driving rod can drive the clamping piece to rotate to the positioning groove or the accommodating cavity; the outer wall of the telescopic rod is provided with a clamping groove matched with the clamping piece.
Under support state and suggestion state, the kickboard does not contact with the telescopic link, and joint spare is located the constant head tank this moment, and its inclined plane is vertical downwards.
