1. INTRODUCTION
The Alpha 6000 is a highly sophisticated industrial radio remote control system. The versatile
features of Alpha 6000 permits its usage in a wide range of industrial applications. The system can
be used to control all types of industrial cranes, tower cranes, building construction equipment,
automatic control systems, mining equipment, and many others.
The Alpha 6000 incorporates numerous advanced safety features and software programming that will
ensure maximum security and safety in the workplace. The major features of Alpha 6000 industrial
radio remote control system are as follow:
*
The system is equipped with highly evolved software that has redundant error checking and
correcting capabilities to ensure 100% error-free transmission, decoding, and control of all
output relays. This highly evolved software includes CRC (Cyclical Redundancy Check) and
Hamming Codes (Error Recovery) programming. The responding time from system error to
receiver auto-shutdown is maximum 1 second.
*
The encoding system utilizes advanced microprocessor control for 100% error-free data
transmission. The availability of 65,536 sets of unique security ID codes + 68 distinct RF
channels will ensure that only commands from a matching control transmitter can be carried out
without any interference from other radio systems.
*
The decoding system utilizes dual-microprocessor control, which will ensure 100% error-free
calculating, bit checking and correcting of all incoming data.
*
The system also utilizes an additional central microprocessor for data comparison and
crosschecking between the two decoding microprocessors. When faults are detected via this
central microprocessor, for maximum safety, the entire system will be shutdown immediately to
avoid possibility of any accidents occurring.
*
The system utilizes PLL synthesized RF transmission. It allows the user to select from 68 sets
of frequency channels best suited for the environment. The frequency channel for transmitter
and receiver is selected via programming software. The receiver also has the ability to
auto-scan from these 68 sets of frequency channels. The receiver will search and locked on to
the intended matching control transmitter.
*
For added safety the receiver also utilizes dual Safety Relays for the receiver MAIN relay
circuit. If the receiver MAIN relay is defective (example: fails to open or close during operation
or not respond to a “Stop” command) a fault will be detected and the system will be shut down
immediately to avoid possibility of any accidents occurring.
*
The Alpha 6000 is equipped with numerous self-diagnosing functions, which include
transmitter low-voltage detection/warning, faulty pushbutton/joystick detection, faulty safety
MAIN relays detection, faulty relay boards detection, faulty EEPROM detection, faulty RX
module detection, incorrect ID code detection, and receiver MAIN auto-deactivation when
transmitter low-voltage is detected, when encountering strong radio interference, and when the
transmitter/operator is out of receiving range.
*
The transmitter is equipped with power auto shutdown function: After 5 minutes of inactivity,
that is 5 minutes after the last pushbutton is released, the transmitter power will shut off
