Abstract

The utility model relates to a batching stirring equipment control system. The system comprises a central control computer, wherein the central control computer is connected with an aggregate transformation control unit, a powder transformation control unit and a liquid material transformation control unit, which are arranged on site, by communication lines. The transformation control units are close to the control equipment, so that wiring is simple and convenient, lots of wires and cables are saved and the antijamming capability is simultaneously improved.

Description

A kind of batching blending plant control system
Technical field
The utility model relates to a kind of batching blending plant control system.
Background technology
Batching blending plant control system adopts centralized control mostly, and all centralized arrangement is in control room for all control devices, computer etc., and field wiring is directly wired to on-the-spot executing agency from control room.The switch input signal of complicated ,Ru executing agency of connecting up is connected to control room with cable and gives control computer; The analog signal of sensor is connected to amplify in control room and gives control computer by shielded cable from each weighing unit; Control the control command of computer and isolated after amplification by relay and contactor, with electric wire, link each equipment.Because batching mixing plant floor space is large, it is wide to distribute, the distance from individual equipment to control room, needs a large amount of electric wire, cable, and brings difficulty to construction; Analog signal, by having decay in cable transport process, is easily interfered again, particularly electromagnetic interference simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of batching blending plant control system, large in order to solve existing centralized control workload, arranges inconvenient problem.
For achieving the above object, scheme of the present utility model is: a kind of batching blending plant control system, it is characterized in that, comprise central control computer, central control computer connects on-the-spot aggregate TCU transfer control unit, powder TCU transfer control unit and the liquid material TCU transfer control unit arranging by connection, and described aggregate TCU transfer control unit, powder TCU transfer control unit and liquid material TCU transfer control unit are respectively used to corresponding be connected on-the-spot control and collecting device.
Described connection is 485 order wires, Ethernet and/or optical cable.
The utility model is partly divided into three control modules according to the layout of mixing plant relatively concentrated aggregate, powder and liquid, each control module detects the switching signal of this unit and the analog signal of conversion sensor, detecting and the switch of conversion and analog signals is communicated by letter with 485 or Ethernet mode sends to central control computer (the adopted optical cable of distance) numerical data, central control computer sends numerical data to each control module with communication or Ethernet mode equally, and each control module is controlled each equipment nearby after receiving digital command.Each TCU transfer control unit is near apart from control appliance, connects up so easy, has saved a large amount of electric wires, cable, has also improved antijamming capability simultaneously.
The utility model has increased the on-the-spot conversion to multi-signal on centralized control basis, on-the-spot aggregate TCU transfer control unit, powder TCU transfer control unit, liquid material TCU transfer control unit are given central control computer the signal after conversion with a communication cable, all control procedures are all processed by central control computer, and on-the-spot TCU transfer control unit is only carried out signal conversion and and central control computer communication.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, a kind of batching blending plant control system, comprise central control computer, central control computer connects the on-the-spot aggregate TCU transfer control unit arranging by connection, powder TCU transfer control unit and liquid material TCU transfer control unit, aggregate TCU transfer control unit, powder TCU transfer control unit and liquid material TCU transfer control unit are connected respectively on-the-spot control and collecting device, each control module is converted to unified communication signal by the signal that comes from collecting device and is transferred to central control computer, the order that on connection, central control technology machine issues is converted to the acceptable signal of control appliance simultaneously.Connection can adopt 485 order wires, Ethernet and/or optical cable.
As a kind of embodiment, aggregate TCU transfer control unit is comprised of a mitsubishi FX2N 32MR PLC basic module and four AD modules, control and the collecting device of aggregate part comprise: the LOAD CELLS of stone one, stone two, sand one and two or four scales of sand, the induction limit switch of door and hopper door, and the relay of magnetic valve and driving magnetic valve etc.Stone one, stone two, the signal of the LOAD CELLS of sand one and two or four scales of sand enters respectively corresponding AD module after amplifier BS-AA amplifies, the induction limit switch of door and hopper door is connected the switch input terminal mouth of basic module, PLC is converted into data signal on-the-spot switch and analog signal and gives by correspondence central control computer, receive the numeric control command of central control computer simultaneously, relay output by basic module after conversion drives magnetic valve or contactor, and then control the opening/closing of door/hopper door of each scale or the start/stop of motor, same, powder TCU transfer control unit is comprised of a mitsubishi FX2N 32MR PLC basic module and four AD modules, the control of powder part and collecting device also comprise LOAD CELLS, induction limit switch and magnetic valve, contactor etc., for the treatment of cement, flyash, breeze etc.Liquid material TCU transfer control unit is also comprised of a mitsubishi FX2N 16MR PLC basic module and four AD modules, for the treatment of water and additive.Control and the collecting device of various concrete aggregates, powder, liquid material all belong to prior art, do not repeat them here.
