Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
With the popularization of mobile terminals such as mobile phones, tablet computers and the like, people carry the mobile terminals while riding in vehicles and use the mobile terminals in the vehicles. The embodiment of the invention provides a method, a device and a system for counting the number of passengers in a vehicle based on a wireless message sent by a mobile terminal.
Referring to fig. 1, a schematic structural diagram of a traffic information display system according to an embodiment of the present invention is shown. The system comprises: at least one vehicle 120, a server 140, and a display terminal 160. Wherein:
the vehicle 120 is a bus or a subway. Alternatively, the travel route of the vehicle 120 may pass through several stations, and the time when the vehicle 120 passes through each station is relatively fixed. The vehicle 120 is provided with a vehicle-mounted terminal 122. The in-vehicle terminal 122 has a capability of transceiving and parsing a Wireless message, which may be a WiFi (Wireless Fidelity) message or a bluetooth message. Optionally, the on-board terminals 122 also have the ability to locate a geographic location and/or the ability to acquire the speed of the vehicle 120. For example, the in-vehicle terminal 122 reads the electronic tag on the station rail through the electronic tag reader to locate the current geographic location; for another example, the vehicle-mounted terminal 122 locates the current geographic location through GPS location technology; as another example, the in-vehicle terminal 122 acquires the speed per hour of the vehicle 120 through an acceleration sensor. The in-vehicle terminal 122 is used for counting the number of passengers in the vehicle 120 and predicting the predicted number of passengers getting on and/or getting off the vehicle 120.
The in-vehicle terminal 122 communicates with the server 140 through a wireless network or a wired network. The in-vehicle terminal 122 is also configured to transmit the number of passengers aboard the vehicle 122 and at least one of the predicted number of boarding and/or disembarking persons to the server 140.
The server 140 may be a server, a server cluster composed of a plurality of servers, or a cloud computing center. The server 140 is configured to receive the number of passengers on the vehicle 122, the predicted number of getting-on passengers and/or the predicted number of getting-off passengers, which are reported by the vehicle-mounted terminal 122.
The server 140 communicates with the presentation terminal 160 through a wireless network or a wired network.
The presentation terminal 160 may be a station bulletin board device 162 or a user device 164. The station bulletin board device 162 may be an electronic bulletin board device disposed at a bus station, or a subway station. The platform bulletin board device 162 can receive the number of passengers on the vehicle 120 pushed by the server 140, and the predicted number of passengers getting on and/or getting off for display; the user device 164 may be a mobile phone, a tablet computer, an e-book reader, an MP3 player (Moving picture Experts Group Audio Layer III, mpeg compression standard Audio Layer 3), an MP4 player (Moving picture Experts Group Audio Layer IV, mpeg compression standard Audio Layer 4), or the like. The user terminal 160 queries the number of passengers on the vehicle 120 and the predicted number of passengers getting on and/or off the vehicle from the server 140 for presentation through a traffic information query client or a web page.
Referring to fig. 2, a flow chart of a passenger counting method according to an embodiment of the invention is shown. The present embodiment is exemplified by applying the passenger number counting method to the terminal 120 shown in fig. 1. The method comprises the following steps:
Optionally, the terminal identification is a MAC (media access control) address.
and step 206, counting the number of passengers in the vehicle according to the appearing time of the mobile terminal.
In summary, the passenger number counting method provided in this embodiment counts the number of passengers in a transportation vehicle by using a wireless message sent by a mobile terminal carried by the passenger; the problem that the applicable scene is limited when the number of passengers is counted through the bus card is solved; the passenger number counting method achieves the effect that the passenger number on the transportation can be dynamically counted no matter whether the user is a card swiping passenger or a coin inserting passenger, and the passenger number can be counted under almost all use scenes of public transportation.
Referring to fig. 3, a flow chart of a passenger counting method according to an embodiment of the invention is shown. The present embodiment is exemplified in that the passenger number counting method is applied to the in-vehicle terminal 120 shown in fig. 1. The method comprises the following steps:
wireless messages include, but are not limited to: WIFI messages and Bluetooth messages. When the mobile terminal starts the WIFI network connection function, the mobile terminal periodically sends a WIFI broadcast message outwards; when the mobile terminal starts the Bluetooth network connection function, the mobile terminal periodically sends out Bluetooth broadcast messages.
Optionally, the wireless message is a broadcast message used for detecting a surrounding available network or connectable equipment, and has a characteristic of periodic transmission; optionally, the wireless message may also be a wireless message sent by the mobile terminal to the vehicle-mounted terminal after the mobile terminal establishes a wireless connection with the vehicle-mounted terminal.
When the mobile terminal sends a wireless message, the mobile terminal carries its own terminal identifier in the wireless message. Optionally, the terminal identity is a MAC address of the mobile terminal.
optionally, when the mobile terminal is far away from the vehicle-mounted terminal, or the mobile terminal is located outside the vehicle and is isolated from most of the signal energy by the vehicle, the signal strength of the wireless message may be deteriorated.
The vehicle-mounted terminal detects whether the signal intensity of each wireless message is lower than the preset intensity, and discards the wireless message when the signal intensity is lower than the preset intensity. That is, the vehicle-mounted terminal can pre-filter some obviously unsatisfactory wireless messages.
since each wireless message carries the terminal identifier of the mobile terminal, the in-vehicle terminal 120 extracts the terminal identifier of the mobile terminal from each received wireless message, and classifies each wireless message according to the terminal identifier. The wireless messages carrying the same terminal identifier are classified into the same category. For example, referring to fig. 4:
for the terminal identification A, four wireless messages A1-A4 are received; for the terminal identification B, 7 wireless messages B1-B7 are received; for the terminal identifier C, 2 wireless messages C1-C2 are received; for terminal ID D, 5 wireless messages D1-D5 are received.
the vehicle-mounted terminal receives 1 or more wireless messages sent by each mobile terminal. When two or more wireless messages carrying the same terminal identification exist, the vehicle-mounted terminal determines the latest group of continuous wireless message sequences. And the receiving time difference between the ith wireless message and the (i + 1) th wireless message in the continuous wireless message sequence is smaller than a preset threshold value, wherein i is a positive integer. The preset threshold value is related to the period of the mobile terminal when the wireless message is periodically sent, and the preset threshold value A corresponding to the WIFI wireless message and the preset threshold value B corresponding to the Bluetooth wireless message can be different.
Referring to fig. 4, for the terminal identity a, the receiving time difference between the wireless packet a1 and the wireless packet a2 is smaller than a preset threshold; the difference in the reception time between the wireless message a2 and the wireless message A3 is less than a preset threshold; the difference in the reception time between the wireless message A3 and the wireless message a4 is less than a preset threshold; the vehicle-mounted terminal determines that the latest group of continuous wireless message sequences corresponding to the terminal identifier A are { A1, A2, A3 and A4 }.
For the terminal identifier B, the receiving time difference between the wireless message B1 and the wireless message B2 is smaller than a preset threshold value; the difference in the reception time between the wireless message B2 and the wireless message B3 is greater than a preset threshold; the difference in the reception time between the wireless message B3 and the wireless message B4 is less than a preset threshold; the difference in the reception time between the wireless message B4 and the wireless message B5 is less than a preset threshold; the difference in the reception time between the wireless message B5 and the wireless message B6 is less than a preset threshold; the difference in the reception time between the wireless message B6 and the wireless message B7 is less than a preset threshold; and the vehicle-mounted terminal determines that the latest group of continuous wireless message sequences corresponding to the terminal identifier B are { B3, B4, B5, B6 and B7 }.
For the terminal identifier C, the receiving time difference between the wireless message C1 and the wireless message C2 is smaller than a preset threshold; the vehicle-mounted terminal determines that the latest group of continuous wireless message sequences corresponding to the terminal identifier C is { C1, C2 }.
For the terminal identifier D, the receiving time difference between the wireless message D1 and the wireless message D2 is smaller than a preset threshold value; the difference in the reception time between the wireless message D2 and the wireless message D3 is less than a preset threshold; the difference in the reception time between the wireless message D3 and the wireless message D4 is less than a preset threshold; the difference in the reception time between the wireless message D4 and the wireless message D5 is less than a preset threshold; and the vehicle-mounted terminal determines that the latest group of continuous wireless message sequences corresponding to the terminal identifier D are { D1, D2, D3, D4 and D5 }.
And 305, determining the appearing time length of the mobile terminal according to the difference between the receiving time of the last wireless message and the receiving time of the first wireless message in the continuous wireless message sequence.
If the vehicle-mounted terminal can receive a group of continuous wireless message sequences of the mobile terminal, the mobile terminal is assumed to be located on the vehicle or near the vehicle in the time period corresponding to the whole continuous wireless message sequence.
Referring to fig. 4, according to the latest group of persistent wireless message sequences { a1, a2, A3, a4} corresponding to the terminal identifier a, the in-vehicle terminal determines that the occurred duration corresponding to the mobile terminal a is: the time T6-T3, which is the time unit obtained by subtracting the time of receipt of the wireless packet a1 from the time of receipt of the wireless packet a4, is 3 time units.
The vehicle-mounted terminal determines that the appearing time length corresponding to the mobile terminal B is as follows according to the latest group of continuous wireless message sequences corresponding to the terminal identifier B as { B3, B4, B5, B6 and B7 }: the time of reception of the wireless message B7 minus the time of reception of the wireless message B3 is T5-T2 is 4 time units.
The vehicular terminal determines that the appearing time length corresponding to the mobile terminal C is as follows according to the latest group of continuous wireless message sequences corresponding to the terminal identifier C as { C1, C2 }: the time T5-T4, which is the time unit obtained by subtracting the time of reception of the wireless message C1 from the time of reception of the wireless message C2, is 1 time unit.
The vehicle-mounted terminal determines that the appearing time length corresponding to the mobile terminal D is as follows according to the fact that the latest group of continuous wireless message sequences corresponding to the terminal identifier D are { D1, D2, D3, D4 and D5 }: the receiving time of the wireless message D1 subtracted from the receiving time of the wireless message D5 is T4-T1 is 4 time units.
It should be noted that, since the receiving operation of the radio packet is continuously performed, after a new radio packet of the mobile terminal is received each time, step 304 and step 305 need to be executed again for the mobile terminal.
the first threshold is a threshold for identifying whether the mobile terminal has left the vehicle. Optionally, the first threshold is equal to the predetermined threshold in step 304, or the first threshold is slightly larger than the predetermined threshold in step 304.
As a possible implementation manner, the vehicle-mounted terminal detects, at predetermined time intervals, whether a difference between the receiving time of the last wireless message in each continuous wireless message sequence and the current time is greater than a first threshold.
As another possible implementation manner, the vehicle-mounted terminal sets a timer for each mobile terminal, the duration of the timer is a first threshold, and the timer is reset each time a new wireless message of the mobile terminal is received; and generating an interrupt signal when the timer is overtime, and considering that the difference value between the receiving time of the last wireless message and the current time is greater than a first threshold value.
When the difference is greater than the first threshold, go to step 307;
when the difference is less than or equal to the first threshold, step 308 is entered.
for each mobile terminal, if the difference value between the receiving time of the last wireless message in the latest group of continuous wireless message sequences and the current time is larger than a first threshold value, the vehicle-mounted terminal judges that the mobile terminal is far away from the vehicle. At this time, the in-vehicle terminal resets the appearing time length of the mobile terminal. The reset mode can be set to 0; or the corresponding storage space can be directly released.
As shown in fig. 4, if the difference between the latest wireless message D5 corresponding to the terminal identifier D and the current time exceeds the first threshold, it is determined that the mobile terminal D has got off the vehicle, or the mobile terminal D is a terminal used by a passerby that accidentally passes through, and the vehicle-mounted terminal sets the appearing time length of the mobile terminal D to 0.
And 308, if the time length is less than or equal to the first threshold, continuing to store the appeared time length of the mobile terminal.
As shown in fig. 4, if the difference between the current time and the latest wireless packet corresponding to the terminal identifier a, the terminal identifier B, and the terminal identifier C does not exceed the first threshold, it is determined that the mobile terminal a, the mobile terminal B, and the mobile terminal C are terminals located on the transportation means, and the in-vehicle terminal continues to store the appeared durations of the mobile terminal a, the mobile terminal B, and the mobile terminal C.
when the time period of the mobile terminal has been short, it is not clear whether the mobile terminal is a mobile terminal used by a passenger who is present in the vehicle or a mobile terminal used by a passerby that has passed by accident. Only mobile terminals that have been present for a long time should be considered as mobile terminals used by passengers located on the vehicle.
For each mobile terminal, it is detected whether the time length of the occurrence of the mobile terminal exceeds a second threshold. Optionally, the second threshold is related to, in a negative correlation with, the vehicle speed of the vehicle. That is, the faster the vehicle speed, the smaller the second threshold value; the slower the vehicle speed, the larger the second threshold value.
When the present time of the mobile terminal exceeds the second threshold, entering step 310;
and when the appeared time length of the mobile terminal does not exceed the second threshold value, counting the mobile terminal temporarily.
And step 310, determining the total number of the mobile terminals with the appeared time length exceeding the second threshold value as the number of passengers in the vehicle.
As shown in fig. 4, assuming that the second threshold is 2 time units, the presence time periods of the mobile terminal a and the mobile terminal B exceed the second threshold, and the in-vehicle terminal determines that the number of passengers is 2.
It should be noted that when the vehicle is in a stop state at the bus stop, there are a large number of passengers getting on and off the vehicle. At this time, the determination logic of steps 309 and 310 may be temporarily set, and when the vehicle is in a driving state other than the bus stop, the determination logic of steps 309 and 310 may be restarted. Steps 309 and 310 may be repeated a plurality of times throughout the travel of the vehicle.
Optionally, after determining the number of passengers, the vehicle-mounted terminal reports the number of passengers, information such as vehicle position, vehicle speed, license plate information, and the like to the server, so that the server provides a traffic information query service to the user terminal.
Because each bus corresponds to some relatively fixed passengers, for example, passenger a will take 105 buses to go to work at 7 am every monday to every friday. As an optional implementation manner, the statistical method for the number of passengers may further include the following steps:
311, analyzing each mobile terminal to obtain a riding experience value of the mobile terminal according to the continuous wireless message sequence of the mobile terminal in the historical time period and the driving route of the vehicle;
the riding experience values comprise: at least one of a vehicle identification empirical value, a boarding station empirical value, a boarding time empirical value, a disembarking station empirical value, and a disembarking time empirical value.
For example, for passenger a, the vehicle-mounted terminal counts that 7 + -5 minutes of morning from monday to friday will take 105 buses to work at the large south gate station, and 5 + -5 minutes of afternoon from monday to friday will take 105 buses to work at the steel bridge station. The corresponding ride experience values are illustratively shown in table one below:
watch 1
| Terminal identification | Empirical value of vehicle identification | Experience value of boarding station | Empirical value of boarding time | Experience value of departure station | Empirical value of alighting time |
| A | 105 routes of Chinese traditional medicine | Large south China station | 6：55-7:05 | Steel bridge station | 4：55-5:05 |
And step 312, predicting the number of passengers getting on or off the vehicle in the running process of the vehicle according to the riding experience value to obtain the predicted number of passengers getting on the vehicle and/or the predicted number of passengers getting off the vehicle.
When the next station of the vehicle accords with the getting-on station experience value in the riding experience values corresponding to the first terminal identification, the predicted arrival time of the next station accords with the getting-on time experience value, and a wireless message carrying the first terminal identification is not received at present (namely the first terminal identification is not on the vehicle), the predicted number of people getting-on is +1 according to the first terminal identification;
and when the next station of the vehicle accords with the get-off station experience value in the riding experience values corresponding to the second terminal identification, the predicted arrival time of the next station accords with the get-off time experience value, and a continuous wireless message sequence corresponding to the second terminal identification exists or the current time length (namely the second terminal identification is on the vehicle) exists, predicting the number of people getting off by +1 according to the second terminal identification.
It should be noted that steps 311 and 312 are generally performed by the in-vehicle terminal. In one possible embodiment, where one vehicle identification corresponds to multiple vehicles, such as 10 buses on 105 roads, steps 311 and 312 may also be performed by multiple on-board terminals corresponding to the same vehicle identification. In another possible embodiment, step 311 and step 312 may also be performed by a server, which is not limited in this embodiment of the present invention.
