Electronics Course Design 20

In this design, the composition, performance, and working principle of the acousto-optic lighting controller are introduced, and the schematic diagram of each circuit and the parameter selection of components are given, and the power-saving effect is very obvious. During the day, when the light is good, no matter how loud the noise of passers-by, it will not be the light bulb that shines. When the light is dark at night, as long as the pickup of the circuit detects a broken sound, it will automatically light up for pedestrian lighting, and then automatically turn off after a few minutes, saving energy.

This circuit uses two-stage control (light intensity sensing and sound intensity sensing).

The light control circuit prioritizes the lighting according to the intensity of the light. The circuit can control the voice-activated delay circuit, and when the light is strong in the daytime, the output of the light-controlled circuit is low to block the voice-activated circuit; At night, when the light is low, the light control circuit outputs a high level, and the voice control function is turned on. In the voice-activated circuit, an amplifier circuit composed of two transistors is used to continuously amplify the electrical signal converted by the MIC, and the time when the lamp is on and on is realized through the delay circuit.

First, the basic steps of the design of electronic circuits:

1. Clarify the requirements of the design task

Fully understand the specific requirements of the design task, such as performance indicators, content and requirements, and clarify the design task. 2. Scheme selection:

According to the knowledge and information, according to the tasks, requirements and conditions proposed by the design, design a reasonable, reliable, economical and feasible design framework, analyze its advantages and disadvantages, and make sure that you know it well. 3. Carry out circuit unit design, parameter calculation and device selection according to the design framework

In the specific design, it can imitate the mature circuit for improvement and innovation, and pay attention to the relationship between signals and limitations; Then, according to the working principle and analysis method of the circuit, the parameters are estimated and calculated. When selecting the device, the parameters such as work, voltage, frequency and power consumption of the components should meet the requirements of the circuit index, the limit parameters of the components must leave sufficient margin, which should generally be greater than the multiple of the rated value, and the parameters of resistance and capacitance should be selected as the nominal value near the calculated value. 4. Drawing of circuit schematic diagram

The circuit schematic diagram is the basis for assembly, welding, debugging and maintenance, and the layout must be reasonable, evenly arranged, clear, easy to see and conducive to reading the circuit diagram; The flow direction of the signal is generally drawn from the input terminal or the signal source, and the service unit circuit is drawn from left to right or from top to bottom according to the flow direction of the signal, and the signal flow direction of the feedback path is the opposite; pictorial symbols and standards with appropriate annotations; The connection should be straight, with the least number of crossings and bends, with interconnected intersections indicated by dots and ground wires represented by ground symbols. Second, the assembly of electronic circuits 4 (6 capacitor leads can not be too long, especially high-frequency bypass capacitors can not have leads.
