Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A road light concentrating type wireless network control system based on radio sensing network, comprising:
Vehicle detection: the mode that adopts infrared detection.Design respectively a transmitting node and a receiving node on both sides of the road, in the infrared signal that does not have to launch under the situation of vehicle, can receive by unobstructed received node; When having Vehicle Driving Cycle, Infrared is blocked, thereby has realized the detection to vehicle.
Street lamp brightness regulates: be used for street lamp to carry out light control.Use at present light fixture to mainly contain high-pressure sodium lamp, LED lamp, fluorescent lamp and incandescent lamp etc., their light regulating circuit is different.
Network control: in the present invention, node is divided into transducer/actuator node and two parts of aggregation node.Transducer/actuator node adopts the MSP430 chip of low-power consumption as main control chip, and transducer/actuator node has wireless routing function, and road transducer has on one side formed a banded route network of static state.Aggregation node adopts the STM32F103VCT6 chip of ST Microelectronics, supports 10M/100M adaptive network, supports that management node carries out remote access to it by the Internet.
The distribution of sensor node of the present invention has certain rule: node is all distributed on straight line on both sides of the road, is similar to two ribbon routes; And the adjacent node in two ribbon routes can carry out communication.According to this rule, designed a kind of banded Routing Protocol, met the lamp that can turn on rapidly vehicle front while detecting vehicle, receive control node the requirements such as control..
Concrete transmission means is as follows:
(1) aggregation node is broadcasted after receiving the group control information of administrative center.Make system can force under special circumstances to control street lamp and enter highlighted, the low bright or state of closing.Guaranteed that same message does not need to repeat to send.Because wireless senser/actor network is comparatively responsive to the consumption of energy, can use in conjunction with the topology of node in the present invention the algorithm that floods of some conserve energy again.
(2) each node carries out multicast after measuring vehicle, and by aggregation node, information is fed back to administrative center.Administrative center analyzes detection case, and as required to aggregation node transmission group control message, aggregation node carries out multicast in respective sets according to information.The independence that has guaranteed message between group, does not influence each other.
(3) administrative center controls individual node at needs or when certain node need to be to administrative center's feedback information, by aggregation node, makes administrative center and individual node carry out clean culture.Realized each node has been inquired about in time, controlled and response.
Concentrating type control method of the present invention is:
To carry out concentrating type control to street lamp, first will obtain the information such as the speed, position of vehicle and size, and then determine and turn on that lamp where, how long turn on the lamp (turning on the number of lamp) of distance.The present invention obtains the size information of vehicle by detecting the length of vehicle.Vehicle is in position in the same time not.As Fig. 3, establishing the speed of vehicle between node 1 and node 2 is v, and the length of vehicle is L1, and the distance between node is L2.T1, t2, t3 constantly the state of vehicle as figure.The infrared sensor that stops node 1 at t1 moment vehicle, node 1, node 2 start timing, and send to node 2 message that vehicle detected; The infrared sensor that stops node 1 at t2 moment vehicle stop, node 1 stops timing, and the time interval is Δ t1; At t3 moment node 2, vehicle detected, node 2 stops timing, and the time interval is Δ t2.
Have:
Δt 1*v=L 1
Δt 2*v=L 2
Form an equation group with 5 parameters, wherein Δ t1, Δ t2 are known parameters.If the length L 2 between node 1 and node 2 is also known, speed v and the length that can obtain vehicle are L1:
V = L 2 t 2 Δ
L 1 = L 2 * t 1 Δ t 2 Δ
For wireless transmission chip belt RSSI (the Received Signal Strength Indication that forms node, received signal strength indicator) chip of function, can adopt the method for finding range in conjunction with packet loss and RSSI to obtain the distance L 2 between node.Generally, also can adopt the method that pre-enters an average to carry out the distance L 2 between defined node.
After the speed v of acquisition vehicle and length are L1, if highlighted street lamp quantity is N, can define a function:
N=f(v,L1).
The positive correlation function that the speed v that wherein function f is vehicle and length are L1, concrete parameter can obtain according to practical experience.Obtain can controlling after highlighted quantity N the state of street-lamp node, realize cluster and control.When vehicle flowrate is more, can temporarily forbid power saving function.
The content not being described in detail in this specification belongs to the known prior art of professional and technical personnel in this area.
