Design and Implementation of a Programmable Locking Quotation Submission Box for Majlis Perbandaran Pasir Gudang

Abstract

The quotation receiver box is designed to address issues with the conventional quotation submission box at Majlis Perbandaran Pasir Gudang (MBPG). Previously, prospective vendors and contractors for a project will submit their quotation in a sealed envelope to a quotation box in MBPG by a strict dateline. However, the process is exposed to flaw where the submission box is not automatically sealed after the cut-off time. Thus, documents can still be submitted after the dateline resulting in reduced integrity to the submission system. The proposed system aims to overcome the issue by introducing a programmable locking system in the quotation submission box to enforce the strict dateline. In this work, the mechanical and electrical design was carried out for the quotation box. The main locking mechanism and user interface was developed with the Raspberry Pi. The fastest average time it takes to lock and unlock the quotation box is 3.52 and 3.61 s respectively. The enhanced box is also able to display the quotation name and dateline. Through a limit switch, the system is also able to count and report the number of quotation submissions.
