The drive circuit of this product is to be based on 16 constant-current LED driving chips of DM13 types, it has the function of error detection.
, as a result can be defeated by alarm signal output terminals A LARM or serial when DM13 is operated in real-time open circuit/short circuit sense mode
Go out data（DAO）Obtain.When there is electric current to flow through output channel, and the passage output voltage is less than 0.2V, then judges that LED is opened
Road, i.e. LED failure.After starting short circuit detecting, if output channel has electric current to flow through, but the passage output voltage is higher than 2/3VCC
When, then judge LED short circuits.
Road traffic signal lamp overall output electric current is finely adjusted by master control IC data-signals, so as to obtain preferably
Homogeneity, physical circuit are as shown in Figure 3.
3. road traffic signal lamp state acquisition module, there is a signal lamp work collection mould in every group of signal lamp the inside
Block, for gathering the working status of each signal lamp, using serial communication mode, uses 9600 baud rates.200ms is gathered once
Signal lamp working status, when there is the working status of local controller inquiry signal lamp, road traffic signal lamp state acquisition mould
Block, local controller is returned to by signal lamp working status.When there is the brightness value that local controller sets signal light path, road
Brightness value is sent to each individual signal lamp lamp panel by road traffic signal light condition acquisition module, and signal lamp lamp panel receives tune
It is as shown in Figure 4 according to the brightness regulation brightness of instruction, physical circuit when saving the instruction of brightness.
4. signal light path local controller；
Signal light path local controller, is the bridge for connecting master system and road traffic signal lamp.Host computer system
System signal is sent to signal light path local controller by network, after signal light path local controller receives instruction, leads to
Cross wireless module and be sent to each signal lamp, wireless module is the ZM516X systems using Guangzhou Zhiyuan Electronics Co., Ltd.
Zigbee wireless modules are arranged, changing module has the features such as high-performance, low work(, should using 2.4-2.5G frequency range application integration schemes
Wireless module theoretical transmission distance is 2km or so, be can be adapted for completely whole to crossing radio communication system, physical circuit such as figure
Shown in 5.
5. wireless transport module,
Since signal light path local controller and road traffic signal lamp state acquisition module wireless module transmit, if
There are two road traffic signal lamp state acquisition modules to send instruction at the same time, and radio channel data will be occupied, causes to count
According to error of transmission, solution method is to use signal light path local controller active inquiry road traffic signal lamp state acquisition mould
Bulk state, ensures only have a module that the ID of signal lamp is recorded and preserved according to position in inquiry data in synchronization, will
The signal location 1 of the inquiry needed, position 1 will be received when receiving the signal lamp position, contrast poll bit and received bit to sentence
It is disconnected whether to have switch data, the data of switch are carried out second and are inquired about, to reduce packet loss, are still deposited after the second inquiry
When packet loss, by data statistics, since the signal lamp at crossing is not in unexpected saltus step, a shape in this direction is read
The light color state of state, and other directional signal light states, calculate packet loss signal lamp state.When signal lamp occur continuous 3S with
Do not processed when upper packet loss.Signal lamp packet loss is about 8% or so when untreated, and data packetloss rate is after handling data
0.2%。
