Resumen
At present, the sewerage inspection is a complex and expensive procedure, in Bogotá and in many other cities of the country there is no diagnosis of even 10% of the total sewerage network. Depending on the company that owns the sewerage network and the type of structure to be inspected, there are different standards and requirements that must be met by the equipment or devices to be used for this purpose. Among the characteristics that the equipment must have, a remote control that allows remote control of the device, lighting systems, sensors and most importantly, allows the capture of photographs and videos of the internal structure of the pipe stands out. For this, the devices are equipped with a camera and transmit images in real time of the state of the pipe, however in most cases the transmission is carried out using wired media such as coaxial or fiber optic cables, which can be impractical since requires lugging large reels of cable to each inspection site. For this reason, the present project arises, which aims to develop a prototype that serves as the basis for a future cheaper equipment and with the advantages of implementing wireless communication compared to existing commercial equipment.
The project begins by explaining the existing terminology regarding sewage structures where an identification of the operating environments and the analysis of the NS-058 standard of the Bogota Aqueduct and Sewerage Company are carried out, which dictates the requirements for the Inspection of the sewage network, in addition, a general study of the technologies available for wireless communication is carried out in order to choose the most appropriate one. From this, the design requirements for the prototype are extracted, a study of existing commercial equipment is carried out and based on this, the functionalities of the prototype are defined, detailing the selection of components, circuit design and necessary connections. The prototype construction procedure is explained together with all the necessary programming to comply with the proposed functionalities, once built, the functional tests are carried out in a real environment and a comparison between the prototype and the existing commercial equipment. Finally, several recommendations that were generated during the development of the project are left for future work.
