Embodiment
In order to be expressly understood the technology contents of the utility model patent, the special detailed description.
Embodiment 1: as shown in Figure 1, and the area loop controller 15 of the utility model and PC 14 and the intelligent roadway illumination and energy saving control system of field node controller 16 formations based on perception.Wherein the communication of PC 14 Surveillance center and area loop controller 15 can be adopted wired mode RS232 bus, and perhaps wireless mode GSM/GPRS adopts custom protocol between PC 14 and the area loop controller.Area loop controller 15 adopts the RS485 bus communication with a plurality of field node controllers 16, and communications protocol is deferred to the MODBUS communications protocol.
MODBUS communication between area loop controller 15 and the field control node is initiated by the area loop controller, is divided into MODBUS inquiry and two types of adjustment.
Area loop controller MODBUS inquiry frame format is by access node number, function code, and initial address, byte number, check code is formed.Field control querying node Echo Frame form is by the field control node number, function code, and byte number, data value, check code is formed, and wherein function code 02 expression enquiring vehicle is through information, 04 expression inquiry brightness degree information.For example the area loop controller sends " 01 02 00 00 00 01 B9 CA " to 485 buses; Then No. 01 field control node response " 01 02 01 00 A1 88 " representes that No. 01 node does not have vehicle and passes through, and No. 01 node of " 01 02 01 01 60 48 " expression has vehicle to pass through.The area loop controller sends No. 01 node brightness degree information of " 01 04 02 00 01 78 F0 " inquiry to 485 buses; No. 1 node of No. 01 field control node response " 01 04 02 00 01 78 F0 " expression hangs down and waits brightness; If " 01 04 02 00 02 38 F1 " representes high brightness, " 01 04 02 00 00 B9 30 " expression is closed.
Area loop controller MODBUS adjustment frame format is by access node number, function code, and initial address, data value, check code is formed.Field control node adjustment Echo Frame form is identical.Function code 06 expression brightness degree adjustment, 05 expression aware switch adjustment.For example the area loop controller sends " 01 06 00 00 00 02 08 0B " to 485 buses and revises No. 01 field control node brightness degree Gao Liang, revises successfully if No. 01 field control node is responded " 01 06 00 00 00 02 08 0B " expression brightness degree.
Communication between area loop controller and the PC is initiated by PC.Frame format is held the address by PC, the area loop controller address, and function code, data field, the verification territory is formed, and frame length is 8 bytes.Function code 0x1000 representes the information of vehicles inquiry, and 0x2000 representes the brightness degree inquiry, and 0x0011 representes to get into the bright pattern of overall height; 0x0021 representes to get into complete low bright pattern; 0x0041 representes to get into the contract fully pattern, and 0x0031 representes to get into the high bright pattern of selectivity, and 0x0051 representes to get into the low bright pattern of selectivity; 0x0061 representes to get into the selectivity " shut " mode", and 0x0101 representes to get into intelligent perceptual model.
After for example PC sends information of vehicles querying command " AA 55 10 00 01 55 D1 72 ", judge the query node number by data field, per 2 bit represent the field control node of a need inquiry, and 0x0155H representes to inquire about 1 ~ 5 field control node.The area loop controller sends MODBUS information of vehicles inquiry frame to selecteed field control node successively; Respectively replied behind the frame information integrated; Return Echo Frame to PC; In Echo Frame, function code is added 0x8000 to show difference, data field is that 0x0001H representes that field control node 1 has vehicle to pass through, and the field control node acquiescence of not inquired about is returned 00B.Similar with it when PC sends the brightness degree querying command, except that the function code difference, difference is the Echo Frame data field, and per 2 bit represent corresponding field control node street lamp brightness, and 00B representes to close, and 01B representes low bright, 02 expression Gao Liang.For example: 0x0155H representes field control node 1 ~ 5 for low bright, and 0x0001H representes that field control node 1 is for low bright.The field control node acquiescence of not inquired about is returned 00B.
PC sends the high bright mode command " AA 55 10 00 01 55 D1 72 " of selectivity, field control node of per 1 bit representation of data field, and 1 expression changes, and 0 expression does not change.0x0155 representes that it is Gao Liang that 1,3,5 nodes in the loop are regulated street lamp brightness, and other node brightness remains unchanged.It is mutual to carry out MODBUS brightness adjustment frame between area loop controller and selected field control node, sends Echo Frame to the PC end again, and expression is operated successfully.
PC sends mode of operation order " AA 55 01 01 FF FF 45 91 ", and the area loop controller gets into the Vehicular intelligent perceptual model.Under this pattern, the area loop controller is opened the intelligent aware switch of each field control node earlier, and field control node luminance recovery is helped low bright.The street lamp of all nodes is regulated with the situation of information of vehicles in the loop; The continuous poll field control of area loop controller node; Find that have vehicle to pass through at continuous 2; Then judge direction of traffic, area loop controller control vehicle is through node and next node selectivity Gao Liang, and the node that went is low bright.If change direction, along adjusting street lamp brightness in the other direction.
