Technical measures for concrete mixing station

Enhance the reliability of commodity measures which?
In order to improve commercial concrete mixing station system reliability in the design to take the following measures:
1, PLC using a separate power supply and the ground wire grounded separately.
2, IPC and the weak part of the power supply through on-line 500W UPS, both purify the weak power supply, but also to ensure that IPC will not lose data due to sudden power loss.
3, requiring commercial concrete mixing stations throughout the system grounding resistance less than 1Ω.
4, IPC and weight instrument control output and alarm input all using photoelectric isolation technology, effectively prevent external interference signal to enter.
5, AC contactor fully installed RC absorption.
6, the intermediate relay line package fully installed diode absorption circuit.
7, all with a variety of weak transmission cable shield wire and shield at one end.
Improve accuracy and production efficiency measures I used to take the shock than n drop curve method for tracking adjustments in the production process can be automatically corrected, but also set a fixed gap. This ensures that the aggregate error of ± 2% or less, while other particles in within ±1%. Pre-processing the data through in a continuous production of said material in advance to improve efficiency.
