Description

Entrance and exit field data statistical method and device based on barrier gate opening and closing

Technical Field

The application relates to the technical field of parking lot management, in particular to an entrance and exit data statistical method and device based on barrier gate opening and closing.

Background

In the actual operation management process of the parking lot, a camera and a barrier gate are installed at the entrance position, and a vehicle to be entered is shot through the camera, so that the barrier gate of the barrier gate is lifted up in a linkage manner to release the vehicle to enter the parking lot; and at the departure position, the identity of the vehicle to be departed is verified, so that the barrier of the linkage barrier is lifted to release the vehicle from the departure position.

At present, other vehicles can continuously enter the parking space as long as the free parking space is ensured based on the departure of the vehicle, so that statistical data of the departure and the entrance of the vehicle can be obtained based on the lifting/falling times of the barrier gate recorded in the departure barrier gate and the lifting/falling times of the barrier gate recorded in the entrance barrier gate.

However, since the camera and the barrier are in one-way communication, and the barrier remote controller can also be configured separately, for example: the gate can be opened by an illegal remote controller by copying the communication protocol. If the barrier is controlled to open and close illegally and no vehicle actually passes through, the barrier opening and closing operation is equivalent to representing an invalid vehicle departure/entry record, and if the invalid departure/entry record exists, the accuracy of the vehicle departure/entry data statistics can be affected. Above, the existing method for counting the entrance and exit data is not accurate enough, and is difficult to find out where the error is, so the quality of the entrance and exit data is not high, and the effective management of the operator to the parking lot can be influenced.

the embodiment of the application provides an entrance and exit data statistical method based on barrier gate opening and closing, and an execution main body is a cloud server, as shown in fig. 2, the following specific steps are provided for the embodiment of the application:

101. and acquiring the opening and closing amount signal data received by the MCU control terminal.

The system comprises an MCU control terminal, a cloud server and a gateway, wherein the MCU control terminal is applied to a barrier gate side, and is internally provided with a Wifi gateway and used for establishing communication with the cloud server based on an Http protocol; and the MCU control terminal can be connected with the barrier gate based on an external pin and is used for receiving opening and closing signal data triggered by the opening and closing operation of the barrier gate.

In the embodiment of the present application, the opening/closing amount signal data includes: the method comprises the steps that high-level signals and low-level signals are correspondingly triggered based on the opening and closing operation of a barrier gate, the high-level signals or the low-level signals are respectively associated with corresponding timestamps, and time points corresponding to the trigger signals are recorded in the timestamps.

Wherein, in this application embodiment, can correspondingly trigger high level signal and low level signal based on the operation of opening and shutting of control banister, based on the preset of different banister manufacturers, one in these two signals indicates that the shelves pole lifts, then another indicates that the shelves pole falls to also corresponding time stamp of utilizing has recorded the trigger time point when every signal is triggered, thereby the time stamp that every signal carried, just can know the time point that a shelves pole lifts or falls.

It should be noted that, the opening and closing amount signal data is correspondingly triggered based on the lifting or falling of the bar of the barrier gate, and several application scenarios for controlling the lifting or falling of the bar of the barrier gate are listed in the embodiment of the present application as follows: 1. when the vehicle drives to the entrance barrier gate, the camera shoots the running vehicle, the stop lever of the barrier gate is controlled to be lifted in a linkage manner, and after the vehicle passes through the barrier gate, the ground sense or the geomagnetism is triggered, and the stop lever of the corresponding barrier gate is controlled to fall in a linkage manner; 2. when a vehicle runs to a barrier gate position of a departure, based on passing verification (the verification mode is not limited in the embodiment of the application), the barrier rod of the barrier gate is controlled to be lifted, after the vehicle runs through the barrier gate, the ground sense or the geomagnetism is triggered, and the barrier rod of the barrier gate is correspondingly controlled to fall in a linkage manner; 3. the barrier gate remote controller is used for controlling the barrier gate rod to lift up or fall down when the barrier gate is out of the field or in the field, and it needs to be explained that the barrier gate remote controller has legal authorization and illegal authorization (such as illegal configuration), and vehicles do not necessarily pass through the barrier gate in the opening and closing process; 4. the barrier gate is abnormally opened and closed due to equipment failure, and vehicles are probably not passed through; the above and other application scenarios control the opening and closing of the barrier.

As for the above-mentioned application scenarios, it should be noted that, in the actual parking lot operation process, the actually encountered application scenarios for controlling the opening and closing of the barrier gate may be various, and there may be an unavoidable situation that "the barrier gate is opened and closed but the vehicle has not passed" and such barrier gate opening and closing operations cannot refer to a valid vehicle entry and exit record, and accordingly, the solution provided by the embodiment of the present invention is to exclude the invalid entry and exit records and obtain more accurate entry and exit data through statistics.

102. And determining the time stamps corresponding to the opening and closing operations of the multiple groups of the barriers and the opening and closing operations of each group of the barriers according to the opening and closing signal data.

In the embodiment of the present application, the opening and closing amount signal data includes: the method comprises the steps that high-level signals and low-level signals are correspondingly triggered based on the opening and closing operation of a barrier gate, the high-level signals or the low-level signals are respectively associated with corresponding timestamps, and time points corresponding to the trigger signals are recorded in the timestamps. Therefore, based on the signal group formed by the adjacent high-level signals and low-level signals, the corresponding one-time barrier gate opening and closing operation can be determined, and based on the time stamps carried by the signals in the signal group, two time points corresponding to the barrier gate opening and closing operation can be known.

103. And acquiring image data matched with a time point recorded by the timestamp based on the timestamp correspondingly associated with the opening and closing operation of the barrier, wherein the image data is image information shot at the entrance position or the exit position.

In the embodiment of the application, the cameras are correspondingly arranged at the entrance and exit positions in the parking lot, and at the entrance position, the cameras can be used for shooting the vehicles to enter the parking lot to lift up the barrier bars of the linkage barrier gates and can also be used for monitoring the security protection purpose to monitor the entrance position; at the departure position, the camera can be but is not limited to monitoring the departure position for security and protection purposes; a large amount of image data of the entrance and exit position can be shot by the camera, and each image can carry shooting time.

Therefore, according to the embodiment of the application, based on two time points recorded by the time stamps corresponding to the associated barrier opening and closing operations at each time, the image data shot at the two time points can be searched from a large amount of image data shot by the camera at the entrance and exit position to serve as the image data matched with the barrier opening and closing operation at the current time.

It should be noted that, in the embodiment of the present application, the storage location and the obtaining manner of the captured image data are not particularly limited, and for example, the captured image data may be obtained from a local backend server.

104. And judging whether the barrier gate opening and closing operation corresponds to effective access record or not based on the image data.

In the embodiment of the present application, after obtaining image data captured in a manner matched with a barrier opening and closing operation, it may be determined whether an effective entry and exit record has occurred based on the barrier opening and closing operation of this time based on the captured content in the image data, for example, whether a vehicle actually passes through after a barrier lever is lifted up, that is: if the vehicle passes through, judging that the entry and exit records are valid; however, if no vehicle passes through the vehicle, it is determined that the entry/exit record is invalid.

And 105a, if the barrier gate opening and closing operation is judged to correspond to the effective entrance and exit record based on the image data, counting the entrance and exit data of the parking lot based on the effective entrance and exit record.

And 105b, if the barrier opening and closing operation is judged not to be corresponding to the valid entry and exit record (namely, the invalid entry and exit record) based on the image data, marking the barrier opening and closing operation, marking the signal data corresponding to the barrier opening and closing operation in the opening and closing amount signal data, and taking the marked data as the invalid entry and exit data.

In the embodiment of the present application, steps 105a and 105b are used as parallel determination results, the embodiment of the present application counts the entrance and exit data of the parking lot based on the valid entrance and exit records, and in addition, the embodiment of the present application is also based on the determined invalid entrance and exit records, so that the embodiment of the present application can perform verification and error correction from a large number of historical barrier opening and closing operations, thereby marking the invalid entrance and exit records as invalid entrance and exit data to be provided to the parking lot operator for data analysis, and greatly facilitating the operator to effectively manage the parking lot no matter from which angle to take measures for strict security protection, troubleshooting equipment failure and the like.

In the above, an embodiment of the application provides a statistical method for entrance and exit data based on barrier opening and closing, an MCU control terminal connected to a barrier is used to send opening and closing amount signal data triggered by barrier opening and closing operations to a cloud server, the cloud server further determines multiple sets of barrier opening and closing operations and timestamps corresponding to each set of barrier opening and closing operations according to the opening and closing amount signal data, and then acquires image data matched with the timestamps, because the image data is image information captured at an entrance position or an exit position, if a vehicle actually runs through the barrier of the barrier when lifted, the vehicle information will be captured inevitably, accordingly, the application determines whether the barrier opening and closing operations correspond to effective exit records by using the image data, and if so, the entrance and exit data of a parking lot are counted based on the effective exit records. The embodiment of the application is so that the cloud server checks the image data shot at the access position of the barrier based on calling, thereby obtaining more accurate access data. Compared with the prior art, the technical problem that an existing method for counting the entrance and exit data is not accurate enough is solved, the method can clearly know which gateway opening and closing operations corresponding to opening and closing amount signal data are not actually effective entrance and exit records based on the checking operation, so that the position of a wrong position in the statistics of the entrance and exit data is clearly known, the manufacturing cost of the gateway is not increased, the method steps are not complicated, the processing efficiency is high, high-quality entrance and exit data are provided for an operator, and effective management of a parking lot is facilitated.

Further, for more detailed explanation, the embodiment of the present application further provides another statistical method for entrance and exit field data based on the opening and closing of the barrier gate, as shown in fig. 3, the embodiment of the present application provides the following specific steps:

201. and acquiring the opening and closing amount signal data received by the MCU control terminal.

Wherein, MCU control end is applied to the banister side, and the volume of opening and shutting signal data includes: the method comprises the steps that high-level signals and low-level signals are correspondingly triggered based on the opening and closing operation of a barrier gate, the high-level signals or the low-level signals are respectively associated with corresponding timestamps, and time points corresponding to the trigger signals are recorded in the timestamps.

In the embodiment of the present application, the present step is explained with reference to step 101.

Particularly, a WiFi gateway is built in the MCU control end provided in the embodiments of the present application, and is used to establish communication with a cloud server based on an Http protocol; and the MCU control end is connected with the barrier gate on the basis of an external pin and is used for receiving opening and closing amount signal data triggered by the opening and closing operation of the barrier gate.

For the embodiment of the application, the MCU control terminal is applied to the barrier gate side, and based on the connection with the barrier gate and the built-in Wifi gateway of the MCU control terminal, the opening and closing amount signal data acquired from the barrier gate are transmitted to the cloud server for checking the entrance and exit data. This application embodiment is equivalent to with the help of the MCU control end of using the banister to the data transmission function of banister has been increased indirectly, and this application embodiment need not to reform transform the manufacturing cost of banister, and the manufacturing cost of MCU control end is also lower, and what this application embodiment provided uses the scheme of MCU control end on the banister, is fit for popularizing and applying in the parking lot more.

202. And obtaining the corresponding time sequence of each signal in the opening and closing quantity signal data based on the time stamp associated with each signal.

In the embodiment of the application, because the signal representation banister shelves pole in the volume of opening and shutting signal data lifts or falls, and based on the different time points that shelves pole lifts or falls, there is time sequence in the time point that records in the timestamp that the signal carries, therefore, based on the timestamp that every signal carried separately, just can be further to each signal time sequencing, namely the time sequence of the operation of lifting or falling of shelves pole many times.

203. And acquiring two adjacent high-level signals and low-level signals from the opening and closing quantity signal data based on the corresponding time sequence of each signal to form a corresponding signal group so as to determine the corresponding barrier gate opening and closing operation.

In the embodiment of the present application, for a plurality of signals included in the switching amount signal data, based on a signal group composed of adjacent high-level signals and low-level signals, a corresponding one-time barrier switching operation can be determined, so as to compose a signal group representing one-time barrier switching operation.

Example 1: if the preset high-level signal represents that the barrier gate of the barrier gate is lifted and the low-level signal represents that the barrier gate of the barrier gate is fallen, selecting the high level with the time sequence in front and the adjacent low level with the time sequence in back to form a corresponding signal group.

Example 2: if the preset condition that the barrier gate of the low-level signal representation barrier gate is lifted and the barrier gate of the high-level signal representation barrier gate falls is adopted, the low-level signal with the time sequence in front and the adjacent high-level signal with the time sequence in back are selected to form a corresponding signal group.

It should be noted that, since the signal group is used to represent one switching operation of the barrier gate, and the sequence of the switching operation of the barrier gate is to lift first and then fall, when two adjacent signals are arbitrarily selected from the switching amount signal data, it should be ensured that the signal corresponding to the lifting is selected first and then the signal corresponding to the falling is selected, and the two adjacent signals must include signals representing the two operations.

204. And obtaining the associated time stamp corresponding to the signal group based on the time stamp associated with the high-level signal and the time stamp associated with the low-level signal in the signal group so as to determine the time stamp corresponding to the opening and closing operation of the barrier gate.

In the embodiment of the application, two timestamps corresponding to each signal group are further obtained according to the established signal groups and the timestamp carried by each signal.

In a special case, when the embodiment of the present application is used for data statistics, a situation that a barrier is lifted without falling may also occur, or a situation that two adjacent representations lift corresponding signals may also exist if data itself is abnormal, then a signal group including only one representation lift corresponding signal is obtained, and then the timestamp corresponding to the signal group is 1.

In such a special case, the entry/exit record may be discarded as an invalid entry/exit record, or a correct entry/exit record may be obtained by correcting the entry/exit record based on the captured image data in the subsequent step 205.

205. And acquiring image data matched with the time point recorded by the timestamp based on the timestamp correspondingly associated with the opening and closing operation of the barrier, wherein the image data is image information shot at the entrance position or the exit position.

In the embodiment of the present application, the step of refining includes the following steps:

firstly, acquiring time points recorded by each timestamp based on the timestamps correspondingly associated with each group of barrier gate opening and closing operations; secondly, obtaining a corresponding time interval based on the determined maximum time point and the determined minimum time point in the time points recorded by the time stamps; and finally, acquiring image data shot in a time interval as image data matched with the time stamp corresponding to each group of barrier gate opening and closing operation.

If the image data matched with the time point recorded by the timestamp is not acquired based on the timestamp corresponding to the barrier gate opening and closing operation, the barrier gate opening and closing operation is determined to correspond to an invalid entry and exit record and marked, so that data analysis is provided for a parking lot operator, and the data analysis is used for effective management of parking.

206. And judging whether the barrier gate opening and closing operation corresponds to effective exit and entry records or not based on the image data.

In the embodiment of the present application, the present step is detailed as follows:

firstly, judging whether the information of the vehicle running through a barrier gate is identified from the image data; and secondly, based on the judgment result, if the judgment result is yes, the barrier gate opening and closing operation is determined as a valid entrance and exit record, if the judgment result is not yes, the barrier gate opening and closing operation is determined as an invalid entrance and exit record, and similarly, the invalid entrance and exit record is marked to provide data analysis for the parking lot operator for effective management of parking.

It should be noted that the vehicle information may be, but is not limited to: license plate information, local vehicle characteristic information and the like, and the purpose is to judge whether a vehicle passes through a gate or not based on vehicle information.

And 207a, if the image data is determined that the barrier gate opening and closing operation corresponds to the effective entrance and exit record, counting the entrance and exit data of the parking lot based on the effective entrance and exit record.

207b, if the image data is determined to judge that the barrier opening and closing operation does not correspond to the valid entry and exit record (i.e. the invalid entry and exit record), marking the barrier opening and closing operation, marking the signal data corresponding to the barrier opening and closing operation in the opening and closing amount signal data, and determining that the data correspond to the invalid entry and exit data based on the marking.
