12Chapter 2. System Configuration 2–1 Transmitter Unit Figure A. Transmitter block diagram The transmitter unit consists of an Encoder Circuit and a Transmitter RF Circuit. When the user presses a pushbutton on the transmitter, the Encoder Circuit senses the pushbutton’s data immediately. The Encoder Circuit then encodes the pushbutton’s data, combined with the ID Code and a Hamming Code to become the "control data". This control data goes to the transmitter RF circuit to modulate a radio frequency (RF) carrier. The output FM signal from the modulator is then sent to the antenna to generate the transmission signal via an RF amplifier and a low-pass filter. 2–2 Receiver Unit Figure B. Receiver block diagram The receiver unit consists of the Receiver/Decoder module and the Relay module. RF signals (control data) from the transmitter are received by the antennas and sent Encoder Circuit Transmitter RF Circuit Pushbuttons Data Antenna Control Data Relay contact outputs (Connects to cranes or other mechanical devices) ANT Control data Receiver/ Decoder Module Relay Module Cable Command
13to the Receiver/ Decoder module. The main functions of the Receiver/Decoder module are to process the RF signal from the transmitter through the signal processing circuits, consisting of the band-pass filter, RF amplifier, mixer, IF amplifier, demodulator, error detection, error correction circuits, and decoder in order to generate a control command sent to the Relay module to drive the corresponding relay. The Relay element is the interface of the Remote Controller to a crane or other mechanical device. The wiring between the relay contact outputs and the control circuit (or control box) of the crane or mechanical device can be arranged by the user. 2-3 Error detection/Error correction by software F25 system employs the theory of "Error-Control Coding" used on Computer system, and incorporates the "Control Data Code" and the principle of "Error detection/Error correction" of Hamming Distance to edit and complete the "Code Word" was so-called "Hamming Code" which may ensure the control data with accuracy in process of transmission, and also equip with function of automatic "Error detection/Error correction" to make sure the safety in operation of F25 system remote control. 2-3-1 Data Stream As shown as below, before the receiver’s relays output to control the equipment’s movement, the data including SYNC, ID-CODE, COMMAND and SUM must be checked twice to further make sure, so the data transmission becomes more safe and reliable. TOTAL DATA LENGTH= 144 bits 2-3-2 Hamming Code ID-CODE COMMAND SUM SYNC SYNC SYNC character 16 bits Security ID-CODE 48 bits with HAMMING ENCODEDAction commands 72 Bits with HAMMING ENCODED Check SUM 8 bits with HAMMING ENCODED
14It is shown as below, the Code Word length is equal to 8, the Data Bit is equal to 4, the Hamming Distance is equal to 4, it means that HAMMING CODE (8,4,4) can correct single-bit errors and also detect double-bit errors.
