Single-lamp controller is connect with the input terminal of solid-state relay SSR, the output end and Switching Power Supply of solid-state relay SSR
The feeder ear of S1 connects；Single-lamp controller is also used to control solid-state relay when the feeder ear for detecting Switching Power Supply S1 powers off
The output end of device SSR switches to the feeder ear of standby lithium pond S2.
Specifically, for single-lamp controller power supply power supply generally select by alternating current (AC220V) be converted to direct current (such as
DC24V Switching Power Supply S1), still, it is contemplated that Switching Power Supply S1 is it is possible that disconnection fault, so the power supply mould of the application
Block not only includes Switching Power Supply S1, further includes standby lithium pond S2 and solid-state relay SSR.Compared with mechanical circuit breaker, Gu
State relay SSR energy consumption is lower, switch speed faster, caused by voltage surge it is less；In addition, as shown in figure 5, the application also exists
Reversed freewheeling diode is added in the input terminal of solid-state relay SSR, is further reduced electricity brought by switching solid-state relay SSR
Press impact of the surge to circuit.
When single-lamp controller detects that power-off occurs for the feeder ear of Switching Power Supply S1 (for example, detecting that supply voltage is unexpected
Become smaller) when, the output end of control solid-state relay SSR switches to the feeder ear of standby lithium pond S2, by standby lithium pond S2
Single-lamp controller power supply is continued as, to guarantee the duration of tunnel illumination.Wherein, the capacity of standby lithium pond S2 is big, density

The brightness of lamp remains unchanged, and guarantees the safety of tunnel illumination.
Single-lamp controller can also continue to after Switching Power Supply S1 is powered off control solid-state relay SSR the reason of exist
In: there are the inductance of large capacity and capacitors in Switching Power Supply S1, after it disconnection fault occurs, remain to maintain a period of time to be single
Lamp controller power supply, this period, enough single-lamp controllers completed power supply switching control.For example, stm8s003f3p6 microprocessor
The speed of service is 16Mz, then the time for executing an elementary instruction is 1/ (16*106The microsecond of)=0.0625 captures power-off signal
It takes around and executes thousand elementary instructions, still in Microsecond grade.
Solid-state relay is started by single-lamp controller in addition, why selecting, other than the above-mentioned response time is fast, due also to
Single-lamp controller can export the driving current for being enough to drive the output end of solid-state relay SSR to switch.
As it can be seen that LED illumination device 3 itself has the function of current failure emergency, so without additionally adding other one in tunnel
Emergency light is covered, driver's sight is impacted so as to avoid excessive lamps and lanterns, and save the illumination cost in tunnel.

Barrier；
For sampling the second sampling resistor for flowing through the second electric current of electrolytic capacitor in constant-current driven module；Single-lamp controller
It is also used to judge the second electric current of sampling whether in default second current range, if so, electrolytic capacitor is normal；If it is not, then
Electrolytic capacitor failure.
Specifically, it is contemplated that when the device failure in circuit, the electric current for flowing through device can change (for example,
LED tunnel lamp, which works long hours, is easy burn-up or light efficiency decaying, leads to flow through its electric current changing), by a large amount of statistical forms
It is bright, on the electrolytic capacitor that device fault is concentrated mainly on LED tunnel lamp and constant-current driven module includes, so the application respectively from
Dynamic monitoring flows through the curent change of the two, to realize fault detection.
More specifically, the first electric current for flowing through LED tunnel lamp is arranged in the application in advance, the model where in its normal work
Enclose (the first current range).Then, the first electric current of LED tunnel lamp is flowed through by the sampling of the first sampling resistor, and by the of sampling
Whether one electric current is sent to single-lamp controller, finally judge the first electric current in the first set current range by single-lamp controller
It is interior, if illustrating that LED tunnel lamp is normal；If not existing, illustrate LED tunnel lamp failure.

Digital Converter, analog-digital conversion) pin, model stm8s003f3p6, the ADC pin of single-lamp controller takes
Sample input voltage is 0-10V.Then the resistance value of the first sampling resistor selects: assuming that flow through the electric current of LED tunnel lamp as 2A, for by its
It is converted into 0-10V voltage, the resistance value of the first sampling resistor should be R=U/I, i.e. 10/2=5 Ω.In addition, in order to improve sampling
Accuracy, the first sampling resistor choose precision resister.
Similarly, the second electric current of electrolytic capacitor in constant-current driven module is flowed through by the sampling of the second sampling resistor, and will adopted
Whether the second electric current of sample is sent to single-lamp controller, then judge the second electric current in the second set electric current by single-lamp controller
