Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, the traffic equipment monitoring system includes a control center 1, a block unit 2, a road section equipment unit 3, a controller 4, a voltage regulation module 5, a storage unit 6, a maintenance personnel communication unit 7, a GSM module 8, and a current sensor 9. Light sensor 10, geomagnetic sensor 11, street lamp 12.

As shown in Figure 2, there is a street lamp equipment information database 6-1 in the storage unit 6, which includes the unit name and location information of each block, the equipment unit name and location information of each road section, the equipment name model corresponding to the equipment number, each equipment The installation date and service life information, maintenance personnel information.

As shown in Figure 3(a), the equipment monitoring starts, preprocessing the current detection sensor 9, inputting the detected signal and performing preprocessing to determine whether there is equipment, if there is equipment, the controller 4 will transfer to execute the interrupt program. As shown in Figure 3(b), the interrupt program outputs the device number and transmits it to the control center 1 for corresponding processing. As shown in Figure 3(c), after the processing of the device is completed, the controller 4 detects whether a startup instruction is received, and if so, turns on the street lamp 12, otherwise turns off the lamp, starts the light intensity sensor 10 and the pedestrian and vehicle detection sensor 11, when the light intensity The output power of the voltage regulator is 1 when the light intensity is large, and the output power of the voltage regulator is 0 (low power) when the light intensity is small and no one passes by for one minute. Then the output power is 2 (medium power), otherwise the output power is 1 (high power).

As shown in Figure 4, the schematic diagram of the intelligent street lamp system includes the minimum system of STM32, the current sensor detection module; the light sensor module, the geomagnetic sensor detection module, the GSM module, the voltage regulation module, and the street lamp. Where the current sensor detects an abnormal current, it will output a level at the OUT terminal and send it to the PA2 terminal of the controller. Then the controller sends the code corresponding to the device detected by the current sensor to the input terminal of the GSM module connected to the output pins PB10 and PB11 of the controller, and the GSM module transmits the information to the terminal of the control center.

Among them, the light sensor detects the light intensity of the surrounding environment. If the light is strong, it means that it is not very dark. The output information of pin 6 of the sensor is connected to the controller PB4. The controller adjusts the voltage regulator connected to PB7 according to the input information to meet the Corresponding to different power ranges. If the geomagnetic detection device detects that no one passes within 1 minute, the output terminal connected to the controller PC0 of the geomagnetic sensor outputs a low level, and the controller regulates the voltage regulator connected to PB7 according to the input information, so that it is at power level 0, Wait until a person is detected before readjusting the regulator.

Working principle and working process of the present utility model are:

When the current detected by the current detection sensor 9 installed in the line of a certain road section equipment unit 3 in a certain area unit 2 exceeds the normal range, the current detection sensor 9 transmits the equipment information to the controller 4, and the controller 4 outputs the corresponding The device number of the device is assigned to the control center 1. The control center 1 calls the specific information of the equipment corresponding to the equipment number in the information database 6 - 1 and the information of the maintenance personnel, and sends this information to the maintenance personnel through the communication unit 7 . When the corresponding equipment in the equipment information database 6-1 exceeds the service life, the control center 1 screens the expired equipment information, and sends the corresponding equipment information to the maintenance personnel to remind the corresponding equipment to be replaced. After troubleshooting and replacement of equipment, the new equipment information is entered into the information database 6-1.

When the control center 1 sends an instruction to turn on the street light to the controller 4 through the GSM module, the controller turns on the street light 12, and the light sensor 10 detects the light intensity of the surrounding environment. The voltage regulator module 5 makes it on the power gear 1; if the light is weak, it means that the sky is very dark. At this time, consider the size of the pedestrian and traffic flow, and pass the traffic detection device 11 (generally, there is a distance between the two ends of the street lamp section at the beginning, and there is a distance in the road section). Lay electromagnetic induction devices at a certain distance, depending on the surrounding environment) to detect the traffic flow, if the traffic flow is very large, the controller 4 adjusts the voltage regulator module 5 to make it on the power level 2, if the flow is not very large, the controller 4 By regulating the voltage regulator module 5 to make it on the power gear 1; if the pedestrian and traffic detection device detects that no one passes within 1 minute, the controller 4 adjusts the voltage regulator module 5 to make it on the power gear 0, etc. Adjust voltage regulator module 5 to make power gear 9 make corresponding adjustment again when having people.
