A plant for manufacturing, including a plant for applying a coating on parts, comprising:
- a plurality of processing lines, each processing line comprising a plurality of operating units,
- wherein at least some of the operating units comprise a native control processing unit for controlling operating parameters of a corresponding operating unit, and one or more native status sensors connected to the native control processing unit for monitoring a working status of the corresponding operating unit by measuring values of parameters related to the working status of the corresponding operating unit, the one or more native sensors being connected to the native control processing unit, which collects and stores the values of the measured parameters,
- wherein at least some of the native control processing units are connected to a control display that displays the working status of the corresponding operating unit,
- wherein at least some of the native control processing units have loaded therein and execute a program coding an instruction for carrying out a calculation algorithm of QR codes or barcodes, the at least some of the native control processing units executing the calculation algorithm of the QR codes or the barcodes starting from representative data of the corresponding operating unit or from information on the working status of the corresponding operating unit, and providing a graphic result after processing on the control display by an operator,
- wherein one or more of the operating units are provided with an additional sensor measuring an additional operating parameter which is non-natively provided in the corresponding operating unit,
- wherein the additional sensor is connected to a radio-transmitter, the radio-transmitter comprising an electronic module operating according to a Bluetooth® standard to advertise a beacon, the radio-transmitter transmitting, with a pre-set periodicity, a radio signal containing a unique identifier configured to identify the corresponding operating unit,
- wherein the radio-transmitter transmits periodically, together with the unique identifier, measurement data of the additional operating parameter recorded by the additional sensor, the beacon including the additional sensor and having a remote setting channel via radio-frequency communication with an external control device, enabling the beacon and the external control device to exchange data packets, and
- wherein the external control device is configured as a portable device adapted to be carried by the operator and receiving the radio signal transmitted by the radio-transmitter;
- a program loaded on and performed by the portable device, the program being configured to extract a univocal unique identifier of one of the operating units and detect a distance between the operator and the one of operating units through an analysis of features characterizing the radio signal, the features including an intensity of the radio signal;
- a connecting procedure between the portable device and the radio-frequency transmitting device, the connecting procedure enabling a reception of the measurement data of the additional operating parameter recorded by the additional sensor;
- and
- wherein each portable device comprises a camera or sensor configured to scan the QR codes or the barcodes on the control display of the at least some of the operating units, and acquire the visualized graphical result representing information on the representative data of the at least some of the operating units or the information related to the working status of the operating units through a click of the camera or sensor, and
- wherein the information on the representative data of the at least some of the operating units and the information relating to the working status of the at least some of the operating units, and the measurement data coded in the QR codes or the barcodes, and the measurement data of the additional operating parameter about the working status of the corresponding operating unit measured by the additional sensor connected to the radio-transmitter is transmitted by the portable device to a remote server or a cloud, for central common monitoring and management of working conditions of the at least some of the operating units in the plant through a wireless network connection of the portable device with the remote server or the cloud.
