Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, an embodiment of the present application provides an illumination system 10, where the illumination system 10 may include: m microwave radar street lamps 11 and a street lamp controller 12 connected with the M microwave radar street lamps 11, wherein M is an integer more than or equal to 3.
In this embodiment, the M microwave radar street lamps 11 may be disposed in one parcel and located at both sides and a crossing of a road in the parcel, and the street lamp controller 12 is also disposed in the parcel and connected to the M microwave radar street lamps 11 in a wireless communication manner. For example, as shown in fig. 2, microwave radar street lamp 111, microwave radar street lamp 112, microwave radar street lamp 117, and microwave radar street lamp 118 are disposed at both sides of road L in section P, and microwave radar street lamp 111, microwave radar street lamp 112, microwave radar street lamp 117, and microwave radar street lamp 118 are disposed at intersections of road L in section P.
In this embodiment, each microwave radar street lamp 11 may be a street lamp installed with a microwave radar, wherein the microwave radar may be installed on top of the street lamp so as to emit a microwave radar signal. In addition, each microwave radar street lamp 11 is provided with a plurality of lamp beads, and the lighting directions of any two lamp beads are different.
Optionally, the microwave radar street lamp 11 installed at the intersection needs to provide omnidirectional illumination for the whole intersection, and therefore, an illumination area (shown by a dotted line) formed by a plurality of lamp beads of the microwave radar street lamp 11 installed at the intersection covers all areas in the direction of 360 °. For example, as shown in fig. 3, the microwave radar street lamp 11 installed at an intersection has 6 lamp beads 110, which are respectively a lamp bead 1101, a lamp bead 1102, a lamp bead 1103, a lamp bead 1104, a lamp bead 1105, and a lamp bead 1106. The 6 illumination areas formed by the 6 lamp beads 110 are overlapped with each other, and all the areas in the direction of 360 degrees are covered.
Optionally, the microwave radar street lamps 11 installed on both sides of the road need to provide all-round illumination for the road direction, and therefore, the illumination area formed by a plurality of lamp beads of the microwave radar street lamps 11 installed at the intersection can cover the area in the road direction. For example, as shown in fig. 4, the microwave radar street lamp 11 installed at an intersection has 2 lamp beads 110, which are lamp beads 1101 and 1102, respectively. The 2 illumination areas (shown by dotted lines) formed by the 2 beads 110 can cover the areas in the road direction a and the road direction B.
In this embodiment, the street lamp controller 12 may be a terminal that implements wireless communication based on LoRa. In the process that a certain vehicle passes through N microwave radar street lamps 11 of the M microwave radar street lamps 11, N is an integer greater than or equal to 3 and less than or equal to M, the street lamp controller 12 may transmit a microwave radar signal by using each microwave radar street lamp 11 of the N microwave radar street lamps 11, determine the driving direction of the vehicle, and provide illumination only in the driving direction by controlling the corresponding lamp bead 110 in each microwave radar street lamp 11 of the N microwave radar street lamps 11.
How the street lamp controller 12 controls the illumination direction of the microwave radar street lamp 11 will be described below.
Referring to fig. 5, an embodiment of the present application provides a lighting method for a microwave radar street lamp, where the lighting method for the microwave radar street lamp may be executed by a street lamp controller 12, and the lighting method for the microwave radar street lamp may include:
step S100: in the process that a vehicle passes through the microwave radar street lamp, the microwave radar signal emitted by the microwave radar street lamp is utilized to determine that the vehicle is located at a first position at a first moment and determine that the vehicle is located at a second position at a second moment after the first moment.
Step S200: and determining the driving direction of the vehicle according to the first position and the second position.
Step S300: and controlling the microwave radar street lamp to provide illumination only in the driving direction.
The following will explain step S100 to step S300 in detail.
Step S100: in the process that a vehicle passes through the microwave radar street lamp, the microwave radar signal emitted by the microwave radar street lamp is utilized to determine that the vehicle is located at a first position at a first moment and determine that the vehicle is located at a second position at a second moment after the first moment.
Each microwave radar street lamp 11 can continuously transmit microwave radar signals to the direction of the road. The microwave radar signal emitted by each microwave radar street lamp 11 can be received by the microwave radar street lamp 11 after coming back when encountering an obstacle. Each microwave radar street lamp 11 can record the time when the microwave radar signal transmitted and returned by itself is received, and upload the time to the street lamp controller 12.
Further, when a vehicle passes through the N microwave radar street lamps 11 at a first time and reaches a position where the vehicle can be simultaneously detected by the microwave radar signals simultaneously emitted from the N microwave radar street lamps 11, each microwave radar street lamp 11 of the N microwave radar street lamps 11 may upload a time point of emitting the microwave radar signal to the street lamp controller 12 and upload a time point of receiving the microwave radar signal returned by the vehicle. In this way, the street lamp controller 12 can calculate the distance between the vehicle and each microwave radar street lamp 11 at the first time by determining the time difference between the transmission and the reception of the microwave radar signal by each microwave radar street lamp 11. Further, through a preset triangulation algorithm, the street lamp controller 12 may calculate that the vehicle is located at the first position at the first time according to a distance between the vehicle and each microwave radar street lamp 11 at the first time. As the vehicle continues to move, at the second time, the N microwave radar street lamps 11 simultaneously re-transmit the microwave radar signals, and then each microwave radar street lamp 11 in the N microwave radar street lamps 11 may upload the time of re-transmitting the microwave radar signals to the street lamp controller 12 again, and upload the time of re-receiving the microwave radar signals returned by the vehicle again. In this way, the street lamp controller 12 can calculate the distance between the vehicle and each microwave radar street lamp 11 at the second time by determining the time difference between the retransmission and the reception of the microwave radar signal by each microwave radar street lamp 11. Further, through a preset triangulation algorithm, the street lamp controller 12 may calculate that the vehicle is located at the second position at the second time according to the distance between the vehicle and each microwave radar street lamp 11 at the second time.
Step S200: and determining the driving direction of the vehicle according to the first position and the second position.
In this embodiment, the first position and the second position are both expressed in the form of plane coordinates. The street lamp controller 12 obtains a direction vector by subtracting the coordinates of the second position from the coordinates of the first position, and the direction vector is used to indicate the driving direction of the vehicle. In other words, the direction of travel of the vehicle is such that the first position points to the second position.
This is explained below by way of an example.
Referring to fig. 6, at the first moment, the street lamp controller 12 may determine that the distance from the vehicle C to the microwave radar street lamp 113 is L1, the distance from the vehicle C to the microwave radar street lamp 114 is L2, the distance from the vehicle C to the microwave radar street lamp 115 is L3, and the distance from the vehicle C to the microwave radar street lamp 116 is L4. From L1, L2, L3, and L4, it is further determined that the vehicle C is located at the position W1 at the first time. And, at the second moment, the street lamp controller 12 may determine that the distance of the vehicle C from the microwave radar street lamp 11113 is L5, the distance of the vehicle C from the microwave radar street lamp 114 is L6, the distance of the vehicle C from the microwave radar street lamp 115 is L7, and the distance of the vehicle C from the microwave radar street lamp 116 is L8. From L5, L6, L7, and L8, it is further determined that the vehicle C is located at the position W2 at the second timing. Further, the streetlamp controller 12 determines that the traveling direction of the vehicle C is in the direction of the vector X in which the position W1 points to the position W2.
Step S300: and controlling the microwave radar street lamp to provide illumination only in the driving direction.
In this embodiment, the lighting direction of each bead 110 of each microwave radar street lamp 11 is also preset in the street lamp controller 12. Therefore, the street lamp controller 12 can select the illumination direction closest to the driving direction from the illumination directions of the plurality of lamp beads, and control the lamp bead corresponding to the illumination direction in each microwave radar street lamp 11 of the N microwave radar street lamps 11 to emit light, so as to provide illumination in the driving direction.
It should be noted that although the vehicle is only illuminated in the driving direction, the illuminated area can still cover the area on both sides of the vehicle to ensure safety.
In this embodiment, to further improve the lighting efficiency, the street lamp controller 12 may control and adjust the lighting area of each microwave radar street lamp 11 in the M microwave radar street lamps 11.
Specifically, since the vehicle passes through the N microwave radar street lamps 11, after the microwave radar street lamps 11 are controlled to provide illumination only in the traveling direction, the street lamp controller 12 may update the number of times of passing of the vehicle of each microwave radar street lamp 11 in the N microwave radar street lamps 11 by one. In other words, each vehicle passes through each microwave radar street lamp 11 of the M microwave radar street lamps 11, and the street lamp controller 12 may update the number of times that the vehicle passes through each passed microwave radar street lamp 11 of the M microwave radar street lamps 11 by one.
When the current time point reaches the set update time point, the street lamp controller 12 may determine the illumination area of each microwave radar street lamp 11 according to the latest vehicle passing frequency of each microwave radar street lamp 11 in the parcel at the set time point, wherein if the vehicle passing frequency of the microwave radar road is more, the determined illumination area of the microwave radar street lamp 11 is larger, and if not, the determined illumination area of the microwave radar street lamp 11 is smaller. The street lamp controller 12 may correspondingly generate an illumination policy for each microwave radar road according to the illumination area determined by each microwave radar street lamp 11, where the illumination policy is used to instruct the corresponding microwave radar street lamp 11 to provide illumination for the latest determined illumination area. In other words, if the number of vehicle passes through the microwave radar road is larger, the lighting strategy configured for the microwave radar street lamp 11 is used to indicate that the microwave radar street lamp 11 provides lighting for a larger area.
It should be noted that, no matter how the illumination area of each microwave radar street lamp 11 is adjusted, it is necessary to ensure that all the illumination areas of the M microwave radar street lamps 11 after adjustment are superposed to fully cover the illuminated road.
Further, the street lamp controller 12 may issue the determined M lighting strategies to the M microwave radar street lamps 11 in a one-to-one correspondence manner in a LoRa communication manner. As an optional way of issuing M lighting strategies, the street lamp controller 12 may broadcast M lighting strategies to the interior of the parcel, and confirm whether all the M microwave radar street lamps 11 receive the corresponding lighting strategies after the broadcasting is completed.
If it is determined that all the M microwave radar street lamps 11 receive the corresponding lighting strategies, the street lamp controller 12 determines that the M lighting strategies are completely issued.
If it is determined that P microwave radar street lamps 11 in the M microwave radar street lamps 11 do not receive P lighting strategies corresponding to one another, where P is an integer greater than or equal to 1 and less than or equal to M. The street lamp controller 12 predicts a first time length required for sending the P illumination strategies one by one to the P microwave radar street lamps 11 one by one, and predicts a second time length required for broadcasting the P illumination strategies in the parcel.
It can be understood that when the street lamp controller 12 adopts a one-by-one transmission mode, in the process that the street lamp controller 12 transmits the lighting strategy to the corresponding microwave radar street lamp 11 point to point, if the transmission fails, the street lamp controller 12 continues to transmit the lighting strategy to the corresponding microwave radar street lamp 11 point to point until the preset times are reached or the transmission is successful. Then, the street lamp controller 12 sends the next lighting strategy to the next microwave radar street lamp 11 point to point until each microwave radar street lamp 11 in the P microwave radar street lamps 11 ensures that the sending is completed. Therefore, the whole time consumption of the process is the one-to-one corresponding time length for sending one by one.
The illumination strategy of each microwave radar street lamp 11 may not be transmitted once in the one-to-one transmission process. Then the estimated time period for transmitting each lighting strategy needs to be multiplied by a multiple, e.g. 1.6, as the estimated time period for transmitting each lighting strategy when estimating the first time period. Then, the sum of the P estimated durations is the first duration.
Although the transmission speed of one-to-one transmission is higher than that of broadcasting, the time consumption of one-to-one transmission is not necessarily less than that of re-broadcasting because the one-to-one transmission may be transmitted more than once. Therefore, the streetlamp controller 12 may determine the magnitude relationship between the first duration and the second duration.
If the first duration is longer than the second duration, the street lamp controller 12 sends the P lighting strategies one by one to the P microwave radar street lamps 11; if the first duration is less than the second duration, the street lamp controller 12 broadcasts P lighting strategies in the parcel.
Referring to fig. 7 in conjunction with fig. 1, based on the same inventive concept, an embodiment of the present application provides an illumination apparatus 200 for a microwave radar street lamp, which is applied to a street lamp controller 12, and the apparatus includes:
the driving direction determining module 210 is configured to determine that a vehicle is located at a first position at a first time and determine that the vehicle is located at a second position at a second time after the first time by using a microwave radar signal emitted by the microwave radar street lamp 11 in a process that the vehicle passes through the microwave radar street lamp 11; determining the driving direction of the vehicle according to the first position and the second position;
