| Emergency marker lamp is used for emergency or danger area of the LED signal lamp warning on the scene. In order to meet the requirements of modern production life of the people, promote energy saving, and environmental protection concept, I devised a system of emergency warning lamp, composed of a warning lamp and information terminal equipment. Designed for energy saving and environmental protection and low power consumption, it has highly practical value.Firstly, this paper puts forward emergency marker lamp system is a set of energy saving and environmental protection, low power consumption and reliability of the program, and then according to the marker lamp design and principle of reasoning tumbler common in daily life, the final design of the information terminal equipment and supporting emergency marker lamp. Emergency marker lamp single-chip selection Silicon Labs company launched ultra low pressure system on C8051F930. The single chip microcomputer as control core marker lamp, the outstanding characteristics of small size, low power consumption and low power consumption, can be very good to meet the emergency lamp circuit design requirements. Information terminal equipment using single-chip STMicroelectronic company developed a low power controller chip STM8L151, which is used to control the operation of the whole. The lowest power consumption mode STM8L151 microcontroller 0.35 μA, dynamic operation mode for 180 μA/MHz, operating power supply voltage in the range of 1.8V to 3.6V, can work normally in the temperature range of -30 DEG -50 DEG C, and can be used for information terminal equipment.Finally, the prototype of emergency warning lamp system for all aspects of performance testing, and the test results show that, the emergency warning lamp system designed to meet the requirements.Because of the design of the product in the national patent applications, part of the contents related to business secrets, so this paper did not mention about the related content. |
