Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a method for automatically planning a wireless signal acquisition position, and referring to fig. 1, in an embodiment, the method for automatically planning the wireless signal acquisition position includes:
step S10, determining the starting point of the acquisition area, and acquiring the movement parameters and wireless signal parameters of the terminal in the moving process in real time based on the starting point;
the method for automatically planning the wireless signal acquisition position is suitable for acquiring the movement parameters and the wireless signal parameters of a plurality of different positions by automatically controlling the effectiveness of the movement track of the acquisition terminal in the movement process of the indoor area so as to form a closed track map according to the movement parameters and the wireless signal parameters, and the movement area corresponding to the closed track map is the effective acquisition position of the wireless signal. Specifically, the indoor area where the collection position needs to be planned may be each store in a large mall, or each resident in a cell, or an area such as a community store covered with wireless signals, where the wireless signals are WIFI signals, and such an indoor environment area is a collection area. The terminal is a mobile terminal having a mobile information capturing module for acquiring mobile parameters, a wireless signal capturing module for acquiring wireless signal parameters, and a communication module for communicating with the server as shown in fig. 7, and may be a smart phone, a tablet computer, or the like, which is not limited thereto. Understandably, the acquisition area has a starting point position for starting acquisition operation, the starting point position is a starting point of the terminal moving in the acquisition area, the starting point of the acquisition area is determined, the terminal starts moving in the acquisition area with the starting point and moves along the boundary of the acquisition area, such as a wall or a partition, to form a terminal moving track. And acquiring the mobile parameters and wireless signal parameters in the mobile process of the terminal in real time based on the starting point. The terminal moves in the acquisition area, and the movement track of the terminal changes along with time, so that the movement parameters and the wireless signal parameters in the movement process of the terminal are acquired in real time, and the movement track graph generated according to the movement parameters and the wireless signal parameters shows the range of the acquisition area.
Step S20, uploading the mobile parameters and the wireless signal parameters to a server, so that the server can draw a mobile track graph according to the mobile parameters and the wireless signal parameters;
furthermore, after the mobile parameters and the wireless signal parameters of the acquisition area in the mobile process of the terminal are acquired in real time, the mobile parameters and the wireless signal parameters acquired in real time are uploaded to a server in a fixed frequency mode, the server establishes a signal fingerprint library, stores the received mobile parameters and the received wireless signal parameters into the signal fingerprint library, and draws a mobile track graph according to the mobile parameters and the wireless signal parameters. The mobile parameters comprise a mobile speed and a direction angle, and a mobile information capturing module in the terminal acquires the mobile speed and the compass angle in the mobile process of the terminal and converts the compass angle into the direction angle. The moving speed represents the moving speed of the terminal, the direction angle is an N-E direction angle, the north-positive direction is 0 radian in an N-E coordinate system, the ray rotates clockwise from the angle, the result is obtained after the modulo operation is performed on 360 degrees, and the anticlockwise direction is a negative value. The N-E coordinate system is a vertical coordinate system established in the north-east direction, the positive direction of the N axis is the north direction, and the positive direction of the E axis is the east direction. The wireless Signal parameters are a MAC address (media access control address, hardware address identity), SSID (Service Set Identifier), and RSSI (Received Signal Strength) of the WIFI Signal in the acquisition area. The server draws a terminal moving track according to the moving parameters received in real time, and the effectiveness of the terminal moving track in the acquisition area is detected to ensure the effectiveness of the acquisition point and improve the effectiveness of the signal acquisition quality of the terminal in the acquisition area, namely the effectiveness of the moving track is realized to improve the effectiveness of the acquisition result.
And step S30, when the current acquisition point of the terminal is detected to coincide with the starting point, forming a closed track map based on the moving track map at the server, and determining a moving area corresponding to the closed track map as an effective acquisition position of the wireless signal.
Furthermore, the present embodiment shows the range of the acquisition area through the movement trace diagram, and when the movement trace is closed, the closed area can represent the range of the acquisition area. Therefore, when the current acquisition point of the terminal is coincident with the starting point, the movement track of the terminal is indicated to form a closed area, and the current acquisition point is the end point position. The terminal moves along the boundary of the acquisition area, so that the starting position and the end position are set to be the same entrance and exit, the terminal starts to move along the boundary of the acquisition area from the entrance and exit, the terminal goes out from the same entrance and exit of the acquisition area after surrounding the acquisition area for a circle, and the movement track of the terminal forms the closed track of the acquisition area. Correspondingly, when the current acquisition point of the terminal is detected to coincide with the starting point and the terminal moving track forms a closed curve, the server forms a closed track graph according to the moving parameters uploaded in real time and a moving track graph drawn by the wireless signals, and the terminal moving area corresponding to the closed track graph is determined as the effective acquisition position of the wireless signals.
The method for automatically planning the wireless signal acquisition position comprises the steps of determining an initial point of an acquisition area, acquiring mobile parameters and wireless signal parameters in the terminal moving process in real time based on the initial point, uploading the acquired mobile parameters and wireless signal parameters to a server, and drawing a moving track graph by the server according to the received mobile parameters and wireless signal parameters; and when the current acquisition point of the terminal movement is detected to coincide with the starting point, the terminal movement track is a closed curve, the movement track graph drawn by the corresponding server is a closed track graph, and the terminal movement area corresponding to the closed track graph is determined as the effective acquisition position of the wireless signal. According to the scheme, the effective acquisition position is determined according to the movement parameters and the wireless signal parameters acquired in the terminal movement process, the dotting is not dependent on an electronic picture, the effectiveness of the acquisition point is ensured by detecting the effectiveness of the movement track of the terminal in the acquisition area through the server, and the planned effective acquisition position is more accurate.
Further, in another embodiment of the method for automatically planning wireless signal acquisition positions of the present invention, the movement parameters include movement speed and direction angle,
the step of acquiring the mobile parameters in the mobile process of the terminal and the wireless signal parameters of the acquisition area in real time based on the starting point comprises the following steps:
and acquiring the current moving speed, the current direction angle and the current wireless signal parameters in the moving process of the terminal at intervals of preset acquisition time from the starting point.
Further, in this embodiment, a preset acquisition time is preset, and a value of the preset acquisition time is set within a reasonable range, so as to avoid that too short results in too much acquired data, or too long results in too little acquired data, and the range of the acquisition area cannot be reflected. And from the starting point, acquiring the current movement parameters and the current wireless signals in the terminal movement process at intervals of the preset acquisition time, namely acquiring the current movement speed and the current direction angle of the terminal and the current wireless signal parameters. And uploading the current mobile parameters and the current wireless signals acquired according to the preset acquisition time to a server, wherein the time when the corresponding server receives the current mobile parameters and the current wireless signals twice is the preset acquisition time. And taking the received current moving speed as the average speed in the preset acquisition time, so that the displacement of the terminal in the preset acquisition time can be determined according to the preset acquisition time and the current moving speed, and the server can draw a corresponding moving track graph on the N-E coordinate system through the displacement and the direction angle.
Further, referring to fig. 2, on the basis of the first embodiment of the method for automatically planning a wireless signal acquisition position of the present invention, a second embodiment of the method for automatically planning a wireless signal acquisition position of the present invention is provided, and in the second embodiment, the step when it is detected that the current acquisition point of the terminal coincides with the starting point includes:
step S40, judging whether the current acquisition point of the terminal reaches the initial point, and when the current acquisition point of the terminal reaches the initial point, judging whether the stay time of the terminal at the current acquisition point is longer than the preset time;
and step S50, when the staying time of the terminal at the current collecting point is longer than the preset time, judging that the current collecting point of the terminal is coincident with the starting point.
Furthermore, each acquisition region has a corresponding movement track, and the movement tracks are not overlapped. Therefore, when a current acquisition point which is coincident with the starting point is taken as an end point position to form a closed track map, in order to ensure that the closed track map corresponds to an acquisition area, the starting point and the end point of the closed track map need to be read for identification. Specifically, the identification can be performed through the stay time, when the terminal moves to the starting point, the terminal stays at the starting point for a period of time, and when the current acquisition point of the terminal reaches the starting point again, the terminal stays at the current acquisition point for a period of time, so that the mobile terminal is ensured to move in the same acquisition area through the stay time. The embodiment is provided with the preset time, when the terminal moves to the initial position, whether the staying time of the terminal at the initial position is larger than the preset time is judged, and when the staying time is larger than the preset time, the initial position is used as the initial point of the acquisition area. Correspondingly, the current acquisition point of the terminal is judged in the terminal moving process, whether the current acquisition point reaches the starting point again is determined, when the current acquisition point reaches the starting point again, whether the staying time of the terminal at the current acquisition point is more than the preset time is further judged, when the staying time is more than the preset time, the current acquisition point of the terminal is judged to be coincident with the starting point, and the current acquisition point is the end point of the acquisition area. And determining a moving area corresponding to the closed track graph formed from the starting point to the end point as an effective acquisition position of the wireless signal in the acquisition area so as to form a difference with the effective acquisition position of the wireless signal in other acquisition areas.
In addition, the present invention further provides a method for automatically planning a wireless signal collection location, and referring to fig. 3, in a first embodiment of the method for automatically planning a wireless signal collection location of the present invention, the method for automatically planning a wireless signal collection location includes:
step S60, the receiving terminal collects and uploads the mobile parameters and wireless signal parameters in the mobile process in real time based on the starting point of the collection area, and draws a mobile track graph according to the mobile parameters and the wireless signal parameters;
step S70, detecting whether the current drawing point of the moving track map is coincident with the initial drawing point of the moving track map;
and step S80, when the current drawing point of the moving track map is coincident with the initial drawing point of the moving track map, judging that the moving track map forms a closed track map, and determining a moving area corresponding to the closed track map as an effective acquisition position of the wireless signal.
The method for automatically planning the wireless signal acquisition position is suitable for the server, and the server receives the mobile parameters and the wireless signal parameters acquired and uploaded by the terminal in real time and draws a mobile track map according to the mobile parameters and the wireless signal parameters. The mobile terminal moves in the acquisition area to form a movement track, and different points on the movement track represent movement parameters and wireless signal parameters at different positions in the acquisition area. The method comprises the steps of collecting mobile parameters and wireless signal parameters of different points in the moving process of the terminal in real time, uploading the collected mobile parameters and wireless signal parameters to a server in real time, and drawing a moving track graph representing a collecting area by the server according to the mobile parameters and the wireless signal parameters. Meanwhile, in the process of drawing the moving track graph, whether a current drawing point of the moving track graph is overlapped with an initial drawing point of the moving track graph or not is detected, if the current drawing point is overlapped with the initial drawing point, the moving track graph forms a closed track graph, the terminal moving track is a closed track which surrounds the acquisition area for one circle, and the terminal moving area corresponding to the closed track graph is determined as the effective acquisition position of the wireless signals. The server draws a moving track graph according to the uploaded moving parameters and wireless signal parameters, effective collection positions are determined, collection personnel do not need to perform on-site dotting operation after electronic pictures determine dotting positions, labor cost is saved, validity of collection points is guaranteed through validity of the moving track of the server detection terminal in a collection area, and planned effective collection positions are more accurate.
Further, in another embodiment of the method for automatically planning wireless signal acquisition positions of the present invention, the movement parameters include movement speed and direction angle,
the step of drawing a moving track graph according to the moving parameters and the wireless signal parameters comprises the following steps:
step S61, obtaining the time interval of the received current movement parameter and the movement parameter at the last moment, and determining the current displacement according to the time interval and the current movement speed in the current movement parameter;
step S62, judging whether the current displacement and the current direction angle in the current moving parameter are effective according to the current wireless signal parameter and the moving parameter at the last moment;
in step S63, if the current displacement size and the current direction angle in the current movement parameter are valid, the movement trace map is updated according to the current displacement size and the current direction angle.
Furthermore, the moving parameters in the moving process of the terminal comprise a moving speed and a direction angle, the moving speed represents the moving speed of the terminal, the direction angle is an N-E direction angle, the N-E direction angle is a result obtained by performing modulo operation on 360 by using the north-positive direction as 0 radian in an N-E coordinate system and using the angle rotated clockwise, and the counterclockwise direction is a negative value. The N-E coordinate system is a vertical coordinate system established in the north-east direction, the positive direction of the N axis is the north direction, and the positive direction of the E axis is the east direction. When receiving the mobile parameters uploaded by the terminal in real time, acquiring the current time of receiving the current mobile parameters, acquiring the time of receiving the mobile parameters uploaded by the terminal at the last moment before receiving the current mobile parameters, and determining the time interval between the current time and the time at the last moment. And acquiring the time interval of the received current movement parameter and the movement parameter at the previous moment, taking the current movement speed included in the current movement parameter as the average movement speed in the time interval, and determining the current displacement according to the time interval and the current movement speed. Understandably, the terminal may have an abnormal moving track in the moving process, when the moving track is abnormal, the determined current displacement size and the received current direction angle are both invalid, and a moving track graph cannot be drawn according to the invalid current displacement size and the received current direction angle, so that the validity of the current displacement size and the current direction angle needs to be judged. Specifically, a last-time mobile parameter uploaded by a last-time terminal is obtained, and whether the current displacement size and the current direction angle are effective or not is judged according to the last-time mobile parameter and the current wireless signal parameter. And when the current displacement size and the current direction angle are judged to be effective, drawing the current displacement size and the current direction angle on the moving track graph, and updating the moving track graph. The step of judging whether the current displacement size and the current direction angle in the current moving parameter are effective or not according to the current wireless signal parameter and the moving parameter at the last moment comprises the following steps:
step S621, obtaining the RSSI current time sequence rule of the MAC address in the current wireless signal parameter, and comparing the current time sequence rule with the time sequence rule at the last moment to obtain a comparison result;
step S622, determining whether the current displacement and the current direction angle in the current movement parameter are valid according to the comparison result, the SSID, and the movement parameter at the previous time.
Further, the wireless signal parameters comprise a MAC address, an SSID and an RSSI, wherein the MAC address is used for representing the MAC address of the wireless signal transmitting device in the acquisition area, the SSID is used for representing the name of the wireless signal in the acquisition area, and the RSSI is used for representing the strength of the wireless signal transmitted by the wireless signal transmitting device in the acquisition area, and the strength is related to the space physical position and the moving speed. In the moving process of the terminal, the space physical position and the moving speed of the terminal change along with time, so that different track points on the moving track of the terminal have different signal strengths, and the signal strengths have corresponding time sequence rules along with the time change. When the effectiveness of the current displacement and the current direction angle is judged, the RSSI current time sequence rule of the MAC address in the current wireless signal parameters is obtained, the MAC address represents the unique physical address of the terminal, and the RSSI of the MAC address is used for representing the RSSI of the same terminal. And comparing the current time sequence rule with the time sequence rule at the last moment to obtain a comparison result. Understandably, for the same terminal and the same acquisition area, although the terminal moves in the acquisition area, the moving range of the terminal does not exceed the acquisition area, and the signal intensity caused by the movement does not differ too much. Therefore, if the difference between the current time sequence rule and the last time sequence rule is large, the moving track of the terminal is wrong; or the two are the same, the terminal does not move, and the acquired current movement parameters are invalid. The same terminal moves in the acquisition area, the difference between the moving parameters of the current track point in the moving track and the moving parameters of the track point at the previous moment is not large, and when the current moving speed is far higher than the moving speed at the previous moment, the current acquired moving parameters are abnormal; or when the current direction angle is opposite to the direction angle at the previous moment, the terminal is indicated to move towards the direction opposite to the track, and the acquired current movement parameters are also abnormal and are all invalid current movement parameters. In addition, the names of the wireless signals, namely the SSIDs, of different acquisition areas are different, so that when the SSIDs in the acquired wireless signal parameters are always the same or change frequently, the acquired wireless signal parameters are wrong, and the current mobile parameters are invalid. Therefore, whether the current displacement size and the current direction angle are effective or not is judged according to the comparison result of the current time sequence rule and the last time sequence rule, the SSID and the last time movement parameter.
And if the current displacement size and the current direction angle are effective, drawing the current displacement size and the current direction angle on a moving track graph. Referring to fig. 6, a closed trajectory diagram determined by the server according to the current displacement size and the current direction angle in an embodiment is shown, where the side length of each grid is a square with a unit of 1, the collection areas include three collection areas 1, 2, and 3, the dots are the starting points of the three collection areas, respectively, and the direction of the small arrow is the terminal moving direction. Setting an N-E coordinate system, enabling the terminal to move clockwise from a coordinate dot of the N-E coordinate system, and according to the movement parameters uploaded at a preset acquisition time, enabling coordinate points obtained in the N-E coordinate system to be (0, 0), (-1, 1), (-6, 2), (-7, 4), (-14, 8), (-7, 4), (-5, 6), (-4, 7), (-3, 8), (0, 13), (7, 13), (0, 9), (-3, 8), (-1, 6), (0, 6), (2, 6), (6, 2), (2, 6), (1, 3) and (0, 0), respectively; the position coordinates of the acquisition region 1 are changed to (-7, 4), (-14, 8), (-7, 4); the position coordinates of the acquisition region 2 are changed to (-3, 8), (0, 13), (7, 13), (0, 9) and (-3, 8); the position coordinates of the acquisition region 3 are changed to (2, 6), (6, 6), (2, 2), and (2, 6). When the mobile terminal reaches the starting point of the acquisition area 1, the mobile terminal starts to move from the starting point after the starting point stays for a time longer than a preset time, when the mobile terminal moves to the preset acquisition time, a first acquisition point of the acquisition area 1 is obtained, a first coordinate point (-7, 4) and a corresponding first direction angle are obtained after conversion, and the first coordinate point and the first direction angle are drawn into a movement track graph; the terminal continues to move, when the terminal moves to the preset collection time again, a second collection point of the collection area 1 is obtained, a second coordinate point (-14, 8) and a corresponding second direction angle are obtained after conversion, and the second coordinate point and the second direction angle are drawn into a movement track graph; acquiring once every preset acquisition time, and drawing the movement parameters into a movement track graph when the acquired movement parameters are effective; and forming a closed track graph until the position of the terminal is moved to coincide with the starting point, and determining a moving area corresponding to the closed track graph as an effective acquisition position of the wireless signal.
Further, in another embodiment of the method for automatically planning a wireless signal collection position of the present invention, the step of determining whether the current displacement size and the current direction angle in the current movement parameter are valid includes:
and step S64, if the current displacement and the current direction angle in the current mobile parameters are invalid, generating the invalid prompt information of the currently acquired mobile parameters and wireless signal parameters, and issuing the prompt information to the terminal.
Understandably, when the server judges that the current displacement size and the current direction angle in the current mobile parameters are invalid, the server generates the invalid prompt information of the currently acquired mobile parameters and wireless signal parameters, and sends the prompt information to the terminal. The terminal receives the prompt information, changes the moving track, and collects the moving parameters and the wireless signal parameters from the new moving track after the change.
