We have developed electronic engineering projects for the following sectors
PROJECTS ELECTRONIC ENGINEERING FOR vending
Hot product vending machine
Integral solution for vending machine control for the hot product dispensing, with boiler control, communications with payment means under MDB protocol (coin and bill aceptors, and cashless system) and executive protocol, graphic display and GPRS communications.
It allows the control of 40 digital inputs and 40 digital power outputs for motor management, as well as the 1500W boiler temperature control.
It has been developed under the uCOS operating system and ARM architecture.
Smart cash box
Software solution for PC architectures under C# language and Windows operating system, with control of coin acceptor, coin dispenser, bill acceptor, banknote recycler, banknote dispenser and coin diverter, able to be integrated with the most applications common POS.
The system manages each of the devices connected to the equipment, controlling intelligent payments optimizing the least number of currencies, personalized payments, revenue, accounting and failure management.
Vending machine with robotic arm
Integral solution for Vending machine control with robotic arm for product dispensing by weighing. It has electronics for arm control in x and y axes, with current control and detection of limit switches without contacts, precision scale for weighing the product to be dispensed, graphic display, protocols for MDB and executive payments, and USB communications, Ethernet and GPRS.
Distributed hardware system for the control of product supply engines in order to reduce cost.
It has been developed under the freeRTOS operating system and ARM architecture.
Cashless payment system
Cashless system that, connected to a vending machine with MDB protocol, allows you to make payments through mobile phone.
It has been developed under the MQX operating system and ARM architecture for the electronics that is connected to the vending machine and Android operating system for the application of user payments.
Low cost solution panel PC
System composed of LCD screen and Raspberry with the purpose of equipping a conventional vending machine with a low cost and minimal integration panel PC solution, which allows the presentation of commercial videos and next generation graphic frontends.
The man-machine interface has been developed through HTML5, CSS and Node, allowing a very simple customization for each client. Linux operating system
Monitoring and control through Zigbee
Zigbee platform with coordinator system and endpoints that allows the control of isolated inputs and outputs, and different means of payment: MDB, CCTALK, pulses, executive.
The coordinators are connected to a host computer via USB, CDC profile, being able to control up to 240 endpoints per coordinator. Each network created by the coordinator is secured, guaranteeing privacy.
Solution developed under the home automation profile of Zigbee.
