Final year Diploma project Microprocessor Based Volume Detector
•
Need of the Project: As name indicates this equipment is used to measure Volume Volume of certain Geometrical objects. The basic need arises from ‘Forging Industry’ where different dimensions and volume of different objects have to be measured. This project aimed at avoiding human error and tedious job in such industries.
•
Principle of Operation: We used optical principle to measure Volume Volume of different objects. To measure volume of any objects it has to be sensed from all three directions. Here LDR were used as a sensing element and an Electric bulb was used as a Light source. The array of LDRs were placed in X Y and Z axis to sense objects. If object dimension is such that it covers any LDR from the array then corresponding LDR will be in high resistance region and vice versa. Logic converter and Current Drivers (BC 147) in further stage boost current from sensors and corresponding digital output is given to Intel 8085-Microprocessor. Microprocessor Microprocessor will check stat status us of each each LDR LDR in all all thre threee arra arrays ys and compu compute te Leng Length th,, Breat Breath, h, Heig Height ht and volu volume me of the the obje object ct.. Programming was done in Assembly Level Language. 8255 ‘Programmable Peripheral Interface (PPI)” was used to interface the external hardware with 8085 Microprocessor. Microprocessor.

Components used: Neon Lamp- used as a light source. LDRused as optical sensor. sensor. BC 147- Used as a Logic converter and current booster. Microprocessor Intel-8085 was used to compute mathematical part. And other interfacing circuits required were used. Tools used: 8085 Simulink- To simulate program Crock rock Cli Clip - To des desig ign n ci circui rcuitts. PSPICE - To simulate circuits. Expres Expresss PCB PCB - To To design design PCBs. PCBs.
•
Application : In Forging Industry to calculate volume of large no. of objects. In shipping industry transport charges are made as per the dimensions of objects.
Industrial Relevance: This innovative project was implemented three years back. Recently forging Industries like “MGM forge” have implemented this idea in their factory to achieve good accuracy and to avoid monotonous job of worker hence utilizing them for more useful work.
