The invention discloses a novel infrared remote control emission circuit of an intelligent traffic light system, which is mainly designed for an infrared emission system of a traffic flow detection module of the intelligent traffic light system at the crossing of a highway. The novel infrared remote control emission circuit mainly comprises an infrared emission control chip, an infrared ray emitting diode, an oscillating circuit and an amplifying circuit. The infrared emission control chip is an infrared remote control emitter BA5104 chip. The oscillating circuit comprises a capacitor C1 and a capacitor C2. In the amplifying circuit, two triodes V1 and V2 form a Darlington transistor, which serves as the main amplifier. The novel infrared remote control emission circuit has a simple structure, works stably and is accurate in control, thereby being widely applicable to various infrared emission circuits for traffic flow detection.
