This passage is going to talk about the followings of radio remote control for crane:
1) RF circuits used for crane wireless remote controls
2) Automatic frequency hopping and channel
3) Relays for Remote controls
4) Feedback of the remote control
About 30 years ago, analog RF circuits relied on tuned frequency crystals to tune the transmitter and receiver to the same frequency for successful communication.
Even though they are used by some manufacturers today, without notice, these frequency crystals can randomly change their center frequency based on the temperature and humidity of the environment, causing communication interruptions.
These RF circuits are bulky and face many problems. With advances in RF technology, RF integrated circuits can be used, eliminating the need for analog filters by shifting tasks such as signal filtering, channel selection and processing to digital signal processor integrated circuits.
Essentially, costs have dropped and reliability has increased due to advances in technology and integrated chip design and manufacturing.
With the new ICs, you are no longer at the mercy of frequency crystals, and different data modulation techniques (such as phase-shift keying) can be implemented at a much lower price.
Modern radio remote controls can change the operating frequency at will.
If there is interference on a particular channel, the system can automatically shift its frequency to a noise-free channel without the operator knowing about it.
This is called automatic frequency hopping, and it is important to know if your radio remote control system has many channels to hop between.
More channels and more bandwidth means better resistance to narrowband noise.
Relays are used in the receiver box to provide or disconnect power to downstream contactors.
It is important to use a power relay rated sufficient to activate downstream contactors or variable frequency drive I/O. If the relay is not rated correctly and there is not enough margin, the relay may fail with a short circuit.
Relay life is also an important factor, as electromechanical relays are typically rated for 10,000 to 50,000 operations, with approximately 50 operations per minute.
Feedback is the confirmation sent back to the transmitter by the receiver after receiving the signal.
After confirmation, important data can be sent back to the transmitter to be displayed on LCD or LED. The operator can view data such as load weight, crane position, relay operation, etc.
Internally, the transmitter waits for an acknowledgement from the receiver to know if the receiver has received the signal.
