Inspection Methods for Aerial Work Platform Intelligent Control System (1)
The intelligent control system of aerial work platforms needs regular maintenance. On one hand, it can increase the service life of the equipment; more importantly, it ensures the normal and safe use of aerial work platforms, safeguarding your life safety. Next, I will share some maintenance knowledge and precautions for aerial work platforms to ensure your safety.
1. Controller Inspection Methods
1. Appearance Inspection:
Observe whether the controller's appearance has any damage, deformation, or burn marks, and check if the connection wires are secure, with no looseness or disconnection.
2. Function Testing:
Operate the control panel of the aerial work platform to observe whether the controller can receive and process commands normally and monitor the output signals of the controller to ensure the signals are stable and meet design requirements.
3. Parameter Check:
Refer to the parameter settings of the controller, use professional equipment to test parameters such as voltage and current, ensuring they are within normal ranges and that the parameters checked are correct.
4. Fault Diagnosis:
If the aerial work platform exhibits operational anomalies or shaking, check whether the controller has faults due to signal interference or poor grounding. You can also use simple diagnostic methods (such as looking, listening, touching, smelling, etc.) to assist in determining if the controller has faults.
5. Replacement Testing:
If a controller fault is suspected, try replacing the original controller with a spare one to see if the fault is eliminated.
2. Driver Inspection Methods
1. Power Supply Check:
Check whether the power input of the driver is normal, using a voltmeter to measure the voltage at the driver's input terminal, ensuring the power line is securely connected and the voltage is stable and meets design requirements.
2. Signal Check:
Use an oscilloscope or other equipment to monitor the input signal waveform of the driver, ensuring the signal quality is good.
3. Load Testing:
Under safe conditions, conduct load testing on the driver, monitoring the output current and voltage values under load to ensure they do not exceed rated values and that the driver operates normally.
4. Overheating Check:
Check whether the driver's cooling system is functioning well, ensuring the heat sink is not blocked and the fan is operating normally. Use a thermometer to measure the driver's temperature, ensuring it does not exceed the allowable range.
5. Fault Diagnosis:
Check whether the internal circuit components of the driver are damaged or aged, replacing them if necessary. If the driver shows alarms or fault indications, troubleshoot based on the alarm codes or fault indication information.
6. Professional Testing:
Use professional equipment for comprehensive testing of the driver to identify fault points and perform repairs. If the specific cause of the driver's fault cannot be determined, seek help from professional maintenance personnel.
3. Sensor Inspection Methods
1. Connection Stability Check:
Check whether the connection between the sensor and the instrument is stable. If there are irregularities or looseness, it may lead to poor contact between the sensor and the instrument.
2. Appearance Inspection:
Check whether the sensor's appearance has any damage or deformation, and also check if the sensor has any faults.
3. Sensitivity Testing:
Operate the control system of the aerial work platform, triggering the sensor to check if it responds correctly, paying attention to response speed and accuracy.
4. Environmental Adaptation Check:
Some sensors can only work properly in specific environments; check whether the surrounding environment meets the sensor's working conditions.
