Abstract
The utility model relates to a control system capable of preventing electrical control devices of a concrete mixing plant from interfering and belongs to the technical field of a control system structure for the electrical control devices of the concrete mixing plant. The control system capable of preventing the electrical control devices of the concrete mixing plant from interfering comprises a PLC (Programmable Logic Controller), an intermediate relay and an air cylinder solenoid valve. A PLC switching power supply, a switching power supply of the intermediate relay, and a switching power supply of the air cylinder solenoid valve are arranged in the control system and are respectively used for supplying power for the PLC, the intermediate relay and the air cylinder solenoid valve. According to the control system capable of preventing the electrical control devices of the concrete mixing plant from interfering, a plurality of switching power supplies are adopted for supplying the power respectively, the interference of electrical devices is avoided, and therefore, the concrete mixing plant can operate normally.
Description
Technical field
The utility model relates to a kind of control system that prevents the mutual interference of concrete mixing plant automatically controlled device phase, belongs to concrete mixing plant automatically controlled device control system technical field of structures.
Background technology
In the mixing plant electric control system, Switching Power Supply becomes the AC power of 220V the dc source of 24V, and is the electricity consumption devices such as PLC, auxiliary reclay, the cylinder solenoid valve power supply in whole control system.
Traditional way is to come centrally connected power supply with a jumbo Switching Power Supply, be that the electricity consumption devices such as PLC, auxiliary reclay and cylinder solenoid valve share a jumbo Switching Power Supply, can simplify circuit design drawing like this, but owing to using same power supply, each device easily produces the phase mutual interference when work, can cause device to break down when serious, more may cause whole control system paralysis, have a strong impact on the normal production of mixing plant.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and a kind of control system that prevents the mutual interference of concrete mixing plant automatically controlled device phase is provided.
Generally speaking, be that dissimilar device produces interference each other at work mostly, according to this characteristic, the classification that can rely on device is by adopting several Switching Power Supplies to avoid phase mutual interference between device.
The utility model is achieved through the following technical solutions:
A kind of control system that prevents the mutual interference of concrete mixing plant automatically controlled device phase, comprise PLC 1, auxiliary reclay 2, cylinder solenoid valve 3, its special character is to be provided with in system PLC Switching Power Supply 1-1, auxiliary reclay Switching Power Supply 2-1, cylinder solenoid valve Switching Power Supply 3-1, connect respectively PLC1, auxiliary reclay 2, cylinder solenoid valve 3, be respectively its power supply.
The utility model is a kind of prevents that the control system of concrete mixing plant automatically controlled device phase mutual interference from adopting several Switching Power Supplies to power respectively, has avoided the phase mutual interference between the electricity consumption device, and concrete mixing plant can normally be moved.
