If necessary, review should be carried out; 4) for spring hangers (included simple spring, hangers and constant support hangers) it should also be recognized as setting and locking of loads. 5) check the surface quality, folded layering and without cracks, rust and other defects. 5) after completion of the test and control drawing number one by one, by series baled. Color alloy steel parts, the parts marking installation location and rotation about the direction you want. 7.3.14. hangers installation 7.3.14.1 hanger layout a. a clear design of hanger should be installed strictly in accordance with the drawings and designs shall not be installed wrong, missing, etc. B. own arrangement of piping support and hanger set and selection should be based on comprehensive analysis of general layout of piping systems; cold installation of steam pipe with particular attention reserved for compensation of thermal expansion displacement and orientation. C. support systems should be rational to withstand pipe loads, static load and incidental load; reasonable piping displacement; guaranteed under various conditions, stress are within the allowed range. Strength, stiffness, and meet requirements to prevent vibration and soothing water, without affecting the adjacent equipment maintenance and other piping installation and expansion. D. equipment connected to the interface to meet pipeline thrust (torque) limit requirements; increase the stability of piping systems to prevent pipeline .

Therefore, we designed a single chip technology based on 51 multi-functional call queuing system, with voice prompts, LCD display of information tips and other functions, better solution of the queuing system to promote the existence of several practical problems.The authors analyze the situation at home and abroad queuing technology, pointed out that the queuing system in the intelligent use of the advantages of single chip, analysis of a general queuing system and basic functions of the business needs, use of hardware and software co-design approach, proposed queuing systems overall design.Secondly, the paper describes the use of 51 single chip multi bank calling system, and other issues. Queuing system is given three main modules of the hardware and software design, 51 MCU line is based on the host, the voice prompt circuit, LCD display prompts the circuit.Furthermore, the paper on the system hardware and software design and implementation are described, the basic functions of the system are given the simulation results and analysis. This article summarizes the work and problems, and further expand the functions of the system were discussed.The design of microcontroller based on 51 multi-function call queuing system is low cost, simple structure, high reliability, maintenance and operation easy, high cost performance characteristics, with strong applicability and promotional value.Key words： 51 single chip, Queuing system, LCD dis
