Sistema de telemetría para el apoyo al despacho de mercancía mediante el monitoreo del peso de la carga

Nowadays many cases of theft of goods to transporters in our country are seen, this leads to heavy economic losses and to the dissatisfaction of the final consumer since the merchandise is not constantly monitored for a fast action in case of a theft. In addition, they reflect many cases of fines for overload faced by the owners of trucks because they do not know the weight carried by their vehicles continuously. It has been designed a prototype of a telemetry system capable of sensing the weight of the cargo (tolerance allowed) carried by a vehicle and sent that information to a server in the cloud for later monitoring from a web application. The system has a sensing stage, consisting of two metal arms, each one connected to an angular potentiometer that generates an analog signal proportional to the distance between the chassis and the rear axle of the vehicle. This signal varies when the vehicle is loaded or unloaded. The signal is received by a microcontroller that later transmit it through the RS232 protocol to a GSM / GPRS modem. The modem sends the signal, geographic coordinates and vehicle speed to a database in the cloud. Finally, the weight of the load was calculated, obtaining measurements with tolerances less or equal to 10% with the vehicle at rest. The weight calculation was performed in the sniffer of the web application through a calibration equation. This indication is continuously observed through web application, in addition to the location of the vehicle on a map and the graphical variation of the weight of the cargo transported. Also, the web application has the option of consulting historical and marking dispatch routes for monitoring the weight carried by the vehicle. Surveillance functions are executed when the vehicle stops within the previously marked route.
