Illuminating street lamp closes white illumination lamp, and control LED warning lamp closes red warning light;When higher level's optical sensor 15 senses environment
Intensity of illumination weakens, and signal is passed to higher level's microprocessor 11 in host computer 1, and higher level's microprocessor 11 controls LED and shines
Bright street lamp opens white illumination lamp.Similarly, the secondary microprocessor 21 on slave computer 2 passes through the secondary perception of optical sensor 25 environment
Intensity of illumination, controls LED lighting street light and LED warning lamp opens or closes.
If have vehicle to pass through on road, higher level's speed measuring module 16 in host computer 1 detects whether vehicle exceeds the speed limit, and works as vehicle
When hypervelocity, higher level's microprocessor 11 in host computer 1 controls LED lighting street light and closes white illumination lamp, controls LED warning lamp
Open red warning light.When vehicle driving goes out the monitoring range of a node, into next node detection range when, a upper dress
Higher level's microprocessor 11 in setting controls LED lighting street light and opens white illumination lamp, and control LED warning lamp closes red warning
Lamp, wherein the shut-in time of LED warning lamp is delayed according to car speed.
Secondary optical sensor 25 voluntarily controls LED lighting street light according to the environment illumination intensity sensed and closes in slave computer 2
White illumination lamp is closed or opens, when higher level's speed measuring module 16 in host computer 1 detects overspeed of vehicle, higher level's microprocessor 11 is controlled
The RS485 communication interface broadcast warning lamp instruction of host computer 1, so that the LED warning lamp for controlling multiple slave computers 2 opens red police
Lamp is accused, to make multiple LED red warning lamp synchronous flashings.
As shown in figure 5, software receives the instruction of main controller for from node procedure flow chart, extracted from instruction stream effective
Instruction, the corresponding operating executed instruction.

Started with 0x01 (SOH), 0X02 (STX) character, intermediate backpack body contains the data of transmitting, and packet tail contains data packet
It verifies and is finally terminated with 0x04 (EOT).The order of control has:
1, red light, the lamp of closing are opened
2, white lamp is opened, red light is closed
3, white lamp is closed, red light is closed
Wherein, the combination of ADDR represents the number of slave computer 2, and ADDR is that " * " number represents broadcast, and primary control program is all
Slave sends control command.After slave computer 2 receives order, start to execute the switch of lamp, brightness control, and return to ACK operation
Success.
We explain an actual data below:
0x01(SOH) 0x02(STX) 0x31 0x30 0x30 0x31 0x30 0x31 0x32 0x30 CRC 0X04
(EOT)
The IA of transmission is 100, instruction 1: opening red light, the lamp of closing, brightness data: 120
0x01(SOH) 0x02(STX) 0x31 0x30 0x30 0x31(OR 0x30) CRC 0X04(EOT)
The IA of response is 100, operates successfully 1 failure 0
