O presentetrabalho consistiu na elabora??o da estrutura e do protocolo de comunica??o do projetoePoste e tamb?m o tratamento de dados para detec??o de eventos nos sensores localizadosnos postes. Anteriormente a comunica??o com os sensores era local, e quandohavia a necessidade de coleta de dados ou atua??o nestes dispositivos, o operador tinhaque se deslocar at? o alcance da rede local. De posse disso, a proposta tem o interessede aumentar a dinamicidade do sistema, chegando a poss?veis integra??es com sistemasj? existentes para gest?o de ilumina??o. ? levado em considera??o a mesma tecnologiade comunica??o j? existentes entre os sensores, utilizando o protocolo ZigBee operandosobre rede mesh, onde a comunica??o com essa rede ? feita pela internet atrav?s de umgateway. O protocolo desenvolvido, trata da forma??o de quadro em n?vel mais baixo,onde se define in?cio, tamanho, e checagem de erros, utilizado na comunica??o entre osensor, concentrador e servidor; e tamb?m o protocolo de n?vel mais alto, tratando-se deum servi?o que utiliza atributos de nomes para atender requisi??es GET e POST sob oprotocolo HTTP, implementado no servidor de dados, estando dispon?vel para a comunica??ocom os sistemas clientes, no caso, sistemas de gerenciamento de ilumina??o. / The study consists in the structure elaboration and the ePoste project communicationprotocol, which is a system of monitoring by wireless communication with the aim tosensor and act with one or many public lighting points, and also the treatment of data todetect the activity in the sensors located on the posts. Previously the communication withsensors were made in locus and when data collect was necessary or the performance inthe devices, the operator had to move until the net place. Accordingly, the purpose has theconcern to increase the system dynamic, achieving the possible integrations with the systemsalready available to the lighting management. The same technology of communicationbetween the sensors are considerate, using the ZigBee protocol running on the meshnet, the communication with this net is made be internet through a gateway by GPRS,device with two basics functionalities, which bypass for data and the firmware update inthe sensor. This functionality test of data management is being tested; integrate way withlocal net of sensors and the internet data server operates. The protocol developed, besidesincorporating the ZigBee, that it is formation of framework in lower level, where definesbeginning, size and errors check, as well as the communication of sensor with the concentrator,which it is encapsulated in ZigBee; also the protocol of upper level, where thatit is the names, it was developed a platform of service to meet GET and POST requestsbeneath HTTP protocol, this service is implemented in the data server, which availablethe communication with the clients systems, in case, lighting management systems.
