Your work. 1. Design and test a C++ program complete with comments, and good variable names. 2. Think about this controller's mechanical design (almost indestructible) and the easier to use electronic design. Consider how often a boiler's design pressure changes (if ever), and environment of a boiler room. 3. Do you think the computer version of the controller will need to be "hardened" and impact its cost? 4. The metals use for the controller are recyclable, whereas the electronic version, is it? 5. What might you report to your client? 10 LAB Deliverables main.cpp A short report to the client after considering "the work bullets 2,3 and 4 from the previous slide. Situation You are a top designer for the "We Do it all Engineering" team, and a have accepted an assignment from a client. A small building boiler manufacturer wants to modernize its image with new features. Their marketing team has an idea to improve the manufacture's image: more technology. They have a boiler safety device they want you to prototype in software to see if it can be done, and to get your learned feedback. What follows is their pitch. You need to think about it and ask questions so you can (try and) fulfill the assignment. -PRESSURE CONTROL power to burner 0 -GAUGE CEN -SIPHON (MUST BE USED) BOILER MAIN SCALE SET POINT SCREW O Sensitive pressure-actuated diaphragm ex: pands or contracts with pressure variations, moving a lever mechanism which operates the snap switch. INDICATOR A screw on top of the case allows set point adjustment without removing the cover. VAIN SCALE DIFFERENTIAL DIAL Differential is adjusted by means of a dial located inside the case. Pressure controller Operation 1. The Customer sets the controller's CUT-OUT and CUT-IN pressures. 2. Once correctly set, the controller constantly reads the boiler's pressure. 3. If the controller reads a pressure greater than or equal to the CUT- OUT pressure, it will CUT the power to the burner (i.e., turn-off the power to the burner to avoid over pressure and increase heating efficiency). 4. The power to the burner with remain cut until the controller reads a pressure less than or equal to the CUT-IN pressure, at which point the power will be restored to the burner
