the control submodule is connected with the street lamp.
A detection control method of a street lamp fault detection and intelligent alarm control module based on a singlechip comprises the following steps:
1) Setting parameters in a singlechip control submodule according to the starting and running of the street lamp and the current characteristics during faults;
2) The sensor module collects current parameters of the street lamp in real time when the street lamp operates, and sends the current parameters to the singlechip control submodule;
3) The singlechip control submodule compares and calculates the current data according to a preset program and parameters, and when the obtained current data is matched with fault current data, a corresponding fault code is generated, and step 4) is performed simultaneously;
4) The singlechip control submodule sends an instruction to the control submodule to cut off the power supply of the fault street lamp; meanwhile, the fault element codes of the fault street lamps and the specific positions of the street lamps are transmitted to the street lamp management center through the communication module, and street lamp maintenance staff can directly maintain related street lamps according to the transmitted street lamp position information.
Setting parameters in a singlechip control submodule according to the starting and running of the street lamp and the current characteristics during faults in the step 1), namely presetting a condition program according to the rule of the current during the starting and running of the high-voltage sodium lamp before the singlechip in the singlechip control module is used;
for example: when the 70w high-voltage sodium lamp is started, a starting current of 1.6A is generated, and when the high-voltage sodium lamp works normally, the current is reduced to 0.7A (8 UF compensation capacitors are connected in parallel); thus, when a street lamp without faults is started to normally light up, the sensor module detects a one-to-one large current and a small current, and the street lamp is started to normally light up with a relatively constant small current; when the street lamp is damaged, the sensor module can detect no-load current data far lower than the rectifier in the starting and normal operation processes, and according to the characteristics of the detected current data, the singlechip can make a judgment of lamp tube damage, cut off the power supply and send the corresponding fault code and position information to the street lamp management center through the communication module.
