This is a customize solution for a mid range RFID. The purpose of this product is to detect and record automatically the attendance of field staff. For example it good be used construction workers in a construction area , home nurses add patient site, or field staff visiting any other customer site.
The system consistent of a control unit mounted in the field and ID units that are worn by the field staff. Each ID unit has a unique Identifier. The system uses a proprietary protocol and registers ID, IN and OUT timestamp of the field personal and passes the information to the internet to a data collector server for further processing.
The main components of the system are Microchip PIC16F873, a RTC PCF8583 from NXP and the transceiver CC1100. It was done with SMD technology in a 2 layers PCB.
The C1100 is a Highly Integrated MultiCh RF Transceiver Designed for Low-Power Wireless Apps.
The CC1100 is a low-cost sub- 1 GHz transceiver designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz, 400-464 MHz and 800-928 MHz bands.
The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data up to 500 kBaud.
CC1100 provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio.
The main operating parameters and the 64-byte transmit/receive FIFOs of CC1100 can be controlled via an SPI interface.
