On the basis of smart transportation, smart transportation integrates new technologies such as the Internet of Things, cloud computing, big data, mobile Internet and artificial intelligence. Smart transportation is characterized by "wisdom", the foothold is "transportation", and "wisdom" serves "transportation". And the intelligent traffic signal system is the most important to achieve smooth traffic. The current intelligent traffic lights are getting better at intelligent command, but they are facing an embarrassing small problem. After the control system sends out the control command, whether the traffic signal lights are normally on, off and flashing is still a problem to be solved, which is very important for the normal operation of the system. The introduction of electric measurement products can solve this problem conveniently and accurately by measuring the power of the traffic signal lights on and off. We recommend the following electric metering solutions.
