In order to further illustrate the function in the system performed by component, the embodiment of the present invention 2 provides a kind of traffic Lamp intelligent control method signaling process figure.Specifically as shown in Fig. 2, in Fig. 2 only one image acquisition device, one easy for narration Illustrated exemplified by terminal, a right-angled intersection, a traffic lights.

Step 1, the corresponding image information of vehicle flowrate of right-angled intersection where image acquisition device collection, and by the image Information is sent to terminal.

Step 2, terminal is received after image information, after being pre-processed to it, is sent to things-internet gateway.

Step 3, things-internet gateway is being received after the image information of pretreatment, is uploaded onto the server.

Step 4, server is counted according to the image information to the vehicle flowrate in image information.

It should be noted that server is according to image information, it is periodically to carry out statistics to the vehicle flowrate in image information Statistics fixed time period in information of vehicle flowrate.For example, within one minute, the vehicle flowrate of the right-angled intersection.It is general and Speech, in order to ensure the one of direction traffic aisle of right-angled intersection nobody when, traffic lights is no longer on the shape of green light State.And it is to try to ensure that the traffic aisle that now other directions have vehicle to pass through is in running order, so institute herein The fixed time period said substantially will not be very long.And a cycle of this fixed time period exactly traffic lamp on/off.It is therefore preferable that , in present specification, fixed time period can be set as to the fixed numbers for being less than or equal to 1 minute.

Step 5, server calculates the right-angled intersection in fixed time period according to the vehicle flowrate of the right-angled intersection The interior traffic lamp on/off time.

Specifically, right-angled intersection can include east-west direction, two traffic aisles of North and South direction.Or, including east, The traffic aisle in west, south and northern four direction.Wherein, east-west direction is parallel reverse traffic aisle.Similar, North and South direction It is similarly parallel reverse traffic aisle.So, a traffic lights is installed in each direction.Or, right-angled intersection Can also include turn left to turn right to traffic lights.So, it is necessary to which according to the vehicle flowrate of different directions, not Tongfang is calculated respectively To the split of the corresponding traffic lights of traffic aisle, and then control the light on and off time of traffic lights (middle traffic lights etc.).

Hereinafter, it will be discussed in detail it is several above in the case of, how to calculate the light on and off time of traffic lights, here will not It is described in detail.

Step 6, traffic lamp on/off time of the right-angled intersection in fixed time period is forwarded by Internet of Things and sent out Terminal is delivered to, so as to traffic lamp on/off state in fixed time period of the terminal control right-angled intersection and light on and off time.

A kind of traffic lights intelligent control method signaling process provided in an embodiment of the present invention, passes through server, terminal, image Collector and things-internet gateway etc. are acted synergistically, and the intelligent control to traffic lights is realized jointly., can be with by this kind of mode Realization periodically counts the information of vehicle flowrate of each right-angled intersection in fixed time period respectively, and according to when fixing Between in section, the information of vehicle flowrate of each right-angled intersection periodically controls the bright of traffic lights in each fixed time period Go out the time.The green light of further control traffic lights and the light on and off time of red light so that traffic aisle can be fully used. The wasting of resources is avoided, the generation of congested traffic condition is reduced.

For detailed overview embodiment of the present invention, the embodiment of the present invention additionally provides a kind of traffic lights intelligent control method. Specifically as shown in figure 3, Fig. 3 is a kind of traffic lights intelligent control method schematic flow sheet provided in an embodiment of the present invention.This method Including：

Step 310, the information of vehicle flowrate that the corresponding terminal of at least one right-angled intersection of real-time reception is sent.

Sayed specifically, example is performed as described above, the image acquisition device at least one right-angled intersection gathers correspondence in real time The information of vehicle flowrate at crossing, and transmit in the form of images into terminal.After terminal-pair image information is pre-processed, send Into server.

Step 320, each right-angled intersection fixed time period at least one right-angled intersection of periodic statistics Interior information of vehicle flowrate.

Although terminal in real time sends information of vehicle flowrate into server, real-time data are likely to the presence of data Update.Such as, previous second vehicle flowrate is 100, and the latter second then then adds 5 cars in wagon flow.That is to say vehicle flowrate become in order to 105.Consequently, it is possible to which server can not control the light on and off time of traffic lights in real time, then can count in fixed time period Information of vehicle flowrate, then according to the information of vehicle flowrate in fixed time period, control traffic lights the light on and off time.

Step 330, respectively according at least one right-angled intersection in each right-angled intersection fixed time period Information of vehicle flowrate, calculate traffic of each right-angled intersection in fixed time period at least one right-angled intersection The light on and off time of lamp.

Step 340, by friendship of each right-angled intersection in fixed time period at least one right-angled intersection The light on and off time of logical lamp is respectively sent to counterpart terminal.

Specifically, by traffic of each right-angled intersection in fixed time period at least one right-angled intersection The light on and off time of lamp is respectively sent to after counterpart terminal, and the right-angled intersection that counterpart terminal can be sent according to server exists The light on and off time of the light on and off time control traffic lights of traffic lights and light on and off state in fixed time period.

In order to further enrich technical scheme.The embodiment of the present invention additionally provides another traffic lights and intelligently controlled Method processed.It is specific as shown in Figure 4.Fig. 4 is another traffic lights intelligent control method flow signal provided in an embodiment of the present invention Figure.In the method, mainly illustrated by taking a right-angled intersection as an example, in other words, the present embodiment mainly for It is traffic lamp on/off time and the light on and off state for only controlling right-angled intersection.Specifically, this method includes：

Step 410, the information of vehicle flowrate that the corresponding terminal of the right-angled intersection of real-time reception first is sent.

Sayed specifically, example is performed as described above, the image acquisition device in the first right-angled intersection gathers correspondence crossing in real time Information of vehicle flowrate.And transmit in the form of images into terminal.After terminal-pair image information is pre-processed, send to clothes It is engaged in device.Wherein, in embodiments of the invention, the first described right-angled intersection is at least one right-angled intersection Any one right-angled intersection.

Step 420, the information of vehicle flowrate in the first right-angled intersection of periodic statistics fixed time period.

Although specifically, the corresponding terminal of the first right-angled intersection in real time can send information of vehicle flowrate to server In, but data are likely to the presence of data renewal in real time.Such as, previous second vehicle flowrate is 100, the latter second then in wagon flow then Add 5 cars.It that is to say that vehicle flowrate becomes for 105.Consequently, it is possible to which server can not control the cross roads in real time The light on and off time of the traffic lights of mouth, then the information of vehicle flowrate in fixed time period can be counted, then according to fixed time period Interior information of vehicle flowrate, controls the light on and off time of traffic lights.

Step 430, according to the information of vehicle flowrate in the first right-angled intersection fixed time period, the first right-angled intersection is calculated The light on and off time of traffic lights of the crossing in fixed time period.

Specifically, in this example, it is assumed that the first right-angled intersection includes the of control east-west direction vehicle pass-through Second traffic lights of one traffic lights and control North and South direction vehicle pass-through.

So, the information of vehicle flowrate according to the first right-angled intersection in fixed time period, calculates the first right-angled intersection The light on and off time of the traffic lights at crossing, specifically as shown in figure 5, comprising the following steps：

Step 510, the vehicle flowrate that the vehicle flowrate and North and South direction of east-west direction pass through in statistics fixed time period respectively, with And the first right-angled intersection vehicle flowrate summation.

Specifically, the information of vehicle flowrate that server is sent according to terminal first, analyzes the information of vehicle flowrate of east-west direction With the information of vehicle flowrate of North and South direction.Then, the current vehicle flowrate of east-west direction and north and south in statistics fixed time period respectively The current vehicle flowrate in direction.Meanwhile, count the first right-angled intersection vehicle flowrate summation.Certainly, the first right-angled intersection is counted Intersection vehicle flux summation had been performed at step 420 in fact.And be exactly only to be counted in extraction step 420 here As a result it is called.

Step 520, the vehicle flowrate and the first right-angled intersection vehicle flowrate summation of east-west direction in fixed time period are calculated Between the first ratio, and using the first ratio as in fixed time period, the split of the first traffic lights.

Specifically, right-angled intersection vehicle flowrate summation in fixed time period is fixed.The car of east-west direction Flow and the vehicle flowrate of North and South direction are equally fixed.So, can be according to if the vehicle flowrate in some direction is excessive Must ratio, by the slightly longer of this direction green light time control.If on the contrary, the vehicle flowrate in another direction is slightly few When, then can be according to certain ratio, by the more slightly shorter of the time control of this direction green light.And concrete implementation scheme It is exactly proportionally to calculate.It is the vehicle flowrate and the first right-angled intersection wagon flow for calculating east-west direction in fixed time period The first ratio between summation is measured, and using the first ratio as in fixed time period, the split of the first traffic lights.

It is preferred that, if east-west direction does not have vehicle flowrate in fixed time period, server directly can be sent out to terminal Configured information is sent, the green light for controlling east-west direction for instruction terminal goes out.Meanwhile, control the green light of North and South direction.

Step 530, the split according to the first traffic lights in fixed time period, calculates the first traffic lights in the set time The light on and off time in section.

Specifically, fixed time period here can be understood as the cycle of traffic lamp on/off.In general, fixed time period For default time segment value, the default time segment value is less than or equal to 1 minute.And according to the first traffic lights in the set time Split in section, calculates light on and off time of first traffic lights in fixed time period, that is to say and be multiplied by fixation using split Period, calculate the time of the green light in the first traffic lights.It is and the amber light bright time is essentially a fixed value, such as solid Section of fixing time is 1 minute, and the amber light bright time is set as 5s.So, the remaining time is then the first traffic in fixed time period The time of when red in lamp.

And, step 540, calculate the vehicle flowrate and the first right-angled intersection vehicle flowrate of North and South direction in fixed time period The second ratio between summation, and using the second ratio as in fixed time period, the split of the second traffic lights.

It is further preferred that when if North and South direction does not have vehicle flowrate in fixed time period, server can directly to Terminal sends configured information, and the green light for controlling North and South direction for instruction terminal goes out.Meanwhile, control the green light of east-west direction.

It is similar with step 520, the vehicle flowrate of North and South direction and the first right-angled intersection in fixed time period are calculated first The second ratio between intersection vehicle flux summation, then using this ratio as in fixed time period, the second traffic lights it is green Letter ratio.

Step 550, the split according to the second traffic lights in fixed time period, calculates the second traffic lights in the set time The light on and off time in section.

Similar with step 530, fixed time period is the cycle of traffic lamp on/off.And according to the second traffic lights when fixing Between split in section, calculate light on and off time of second traffic lights in fixed time period, that is to say be multiplied by using split it is solid Fix time section, calculate the time of the green light in the second traffic lights.And the amber light bright time is essentially a fixed value, for example Fixed time period is 1 minute, and the amber light bright time is set as 5s.So, the remaining time then hands over for second in fixed time period The time of when red in logical lamp.

Step 440, the light on and off time respectively by first the first traffic lights of right-angled intersection in fixed time period is bright Go out the time, and the light on and off time of light on and off time of second traffic lights in fixed time period is sent to counterpart terminal.

Specifically, during the light on and off of light on and off time by first the first traffic lights of right-angled intersection in fixed time period Between, and the light on and off time of light on and off time of second traffic lights in fixed time period send to counterpart terminal, counterpart terminal The traffic lights of right-angled intersection first and the second traffic lights traffic lights in fixed time period that can be sent according to server Light on and off time control traffic lights the light on and off time and light on and off state.

A kind of traffic lights intelligent control method provided in an embodiment of the present invention, by counting east-west direction, the South and the North respectively To traffic aisle vehicle flowrate, and the first right-angled intersection vehicle flowrate summation.East-west direction traffic aisle is calculated respectively The first ratio between vehicle flowrate and the vehicle flowrate summation of the first right-angled intersection, and North and South direction traffic aisle vehicle flowrate The second ratio between the vehicle flowrate summation of the first right-angled intersection.And it regard the first ratio as east-west direction traffic aisle The split of corresponding traffic lights, the further light on and off time for calculating the first traffic lights in fixed time period.By the second ratio It is worth the split as the corresponding traffic lights of North and South direction traffic aisle, further calculates the second traffic lights in fixed time period The light on and off time.By the whole mode, the light on and off time of different directions traffic lights can be periodically adjusted, it is ensured that traffic aisle On the premise of making full use of, the generation of traffic jam environment is avoided as far as possible.

Further, if the first right-angled intersection includes east, west, south and northern four traffic aisles, control first The method of the traffic lamp on/off time and light on and off state of right-angled intersection, the key step of this method, with a upper embodiment In method and step it is same or similar, it is unique unlike step in step 430, fixed according to the first right-angled intersection Information of vehicle flowrate in period, when calculating the light on and off time of traffic lights of first right-angled intersection in fixed time period, Specific calculating process is different.

Therefore, other steps are repeated no more here, are only discussed in detail down：When the first right-angled intersection includes east, west, south During with northern four traffic aisles, the specific implementation procedure of step 430.It is specific as shown in Figure 6.

The process can include：

Step 610, the vehicle flowrate of East, West, South, North four direction in fixed time period, and the first cross are counted respectively Intersection vehicle flowrate summation.

Specifically, the information of vehicle flowrate that server is sent according to terminal first, analyzes east, west, south and 4, north direction Information of vehicle flowrate.Then, in statistics fixed time period Nei Dong respectively, west, the current vehicle flowrate in south and 4, north direction.Meanwhile, system Count out the first right-angled intersection vehicle flowrate summation.Certainly, an as above embodiment, the first right-angled intersection vehicle flowrate of statistics is total Performed at step 420 in fact.And be exactly only that the result counted in extraction step 420 is adjusted here With.

Step 620, the vehicle flowrate of the East, West, South, North four direction in fixed time period is calculated respectively, with the first cross Ratio between the vehicle flowrate summation of intersection.

Specifically, right-angled intersection vehicle flowrate summation in fixed time period is fixed.East and west to car Flow is fixed.It is similar, south and north to vehicle flowrate be equally fixed.So, if the vehicle flowrate in some direction When excessive, can according to must ratio, by the slightly longer of this direction green light time control.If on the contrary, another , then can be according to certain ratio, by the more slightly shorter of the time control of this direction green light when the vehicle flowrate in direction slightly lacks. And concrete implementation scheme is exactly proportionally to calculate.It is to calculate fixed time period Nei Dong, west, south and northern 4 directions respectively Vehicle flowrate and the first right-angled intersection vehicle flowrate summation between ratio.

Step 630, the vehicle flowrate of the East, West, South, North four direction in fixed time period is handed over the first cross respectively The ratio between intersection vehicle flux summation is pitched, split of the traffic lights of correspondence direction in fixed time period is used as.

It is preferred that, if any of east, west, south and 4, north direction direction do not have vehicle flowrate in fixed time period, Server directly can send configured information to terminal, and the green light for controlling the direction for instruction terminal goes out.Meanwhile, control is therewith The green light of opposite direction.

Step 640, respectively according to the traffic lights of correspondence direction in fixed time period split, calculate correspondence direction friendship Logical light on and off time of the lamp in fixed time period.

Specifically, fixed time period here can be understood as the cycle of traffic lamp on/off.In general, fixed time period For default time segment value, the default time segment value is less than or equal to 1 minute.And respectively according to east, west, south and 4, north Split of the traffic lights in direction in fixed time period, corresponding east, west, south and northern 4 directions of calculating are in fixed time period The light on and off time, that is to say using when corresponding split is multiplied by fixed respectively in each direction in east, west, south and northern 4 directions Between section, calculate the time of the green light therewith in the corresponding traffic lights in direction.And the amber light bright time is essentially a fixation Value, such as fixed time period is 1 minute, and the amber light bright time is set as 5s.So, the remaining time is then in fixed time period The time of when red in first traffic lights.

In addition, reader should be understood that the vehicle of east-west direction here in parallel reversely lanes, North and South direction Vehicle is in parallel reverse lanes.

A kind of traffic lights intelligent control method provided in an embodiment of the present invention, by counting 4 sides of East, West, South, North respectively To traffic aisle vehicle flowrate, and the first right-angled intersection vehicle flowrate summation.And East, West, South, North 4 is calculated respectively Ratio between direction traffic aisle vehicle flowrate and the vehicle flowrate summation of the first right-angled intersection.And calculate each telegoniometer Ratio respectively as the split of the corresponding traffic lights of direction traffic aisle, further calculate direction traffic lights and exist The light on and off time in fixed time period.By this kind of mode, the light on and off time of different directions traffic lights can be periodically adjusted, Ensure that traffic aisle avoids the generation of traffic jam environment on the premise of making full use of, as far as possible.

Further, if the first right-angled intersection also include turn left traffic lights and/or turn right traffic lights when, need The method for performing the traffic lamp on/off time and light on and off state of the first right-angled intersection of another control.Similar, this method Key step, it is same or similar with method and step in a upper embodiment, it is unique unlike step in step 430 In, according to the information of vehicle flowrate in the first right-angled intersection fixed time period, the first right-angled intersection is calculated when fixing Between traffic lights in section the light on and off time when, specific calculating process is different.

Therefore, other steps are repeated no more here, are only discussed in detail down：

In the first case, when the first right-angled intersection includes turning left to lamp traffic lights, handed over according to the first cross The cross road turning left to information of vehicle flowrate mouthful in fixed time period, calculate the first right-angled intersection turn left to traffic lights it is bright Go out the time method flow it is as shown in Figure 7.

This method includes：

Step 710, extract and turned left in preset time period at least twice to information of vehicle flowrate.

Specifically, because whether vehicle needs to turn left or turn right, the image gathered from image acquisition device can not judge.That , how to calculate in fixed time period, traffic lamp on/off time when vehicle turns left.

In the present embodiment, mainly using the wagon flow turned left in the statistical history period (i.e. in preset time period) Amount, then according to the vehicle flowrate in historical time section, in estimation fixed time period, during traffic lamp on/off when vehicle turns left Between.
