Description

Technical Field

[0001] The utility model relates to a concrete production control system, in particular to an integrated control system for the entire process of temperature-controlled concrete production. Background Art

[0002] Concrete is a mixture of aggregates (large, medium and small stones and sand), cementitious materials (cement and fly ash), admixtures and water in a certain proportion and stirred evenly. After a period of curing, it forms a mixture with certain compressive and tensile strength. There is an exothermic hydration reaction inside the newly mixed concrete, and this process generally ends slowly after dozens of days or even longer. Since the hydration reaction can cause fission of concrete components, reduce strength, and bring serious engineering quality problems, the temperature of the poured concrete in the warehouse and the outlet temperature of the concrete production process are often strictly controlled in the field of hydraulic engineering. The main temperature control methods in the concrete production process include aggregate air cooling, water cooling, ice mixing, steam heating, etc.

[0003] The production process of temperature-controlled concrete mainly includes weighing, weighing and storing raw materials (mainly aggregates and cementitious materials), feeding of aggregates (belt conveyor), feeding of cementitious materials (storage pump pumping or compressed air extraction), cooling (or heating) of aggregates, weighing and batching of various raw materials including admixtures and water, mixing, control of concrete discharge from warehouse, transportation of concrete to site unloading, weighing of empty concrete transport vehicles, sewage treatment, air compressor control, etc. Among them, weighing, batching, mixing and control of concrete discharge from warehouse are carried out in the mixing plant, which is generally supplied as a complete set by the manufacturer. Aggregate precooling and preheating and weighing and weighing systems are also supplied as a complete set by the manufacturer. The other links are basically self-contained systems, and the coordination between the links is basically manual. Under this production mode, not only is it difficult to ensure the quality of concrete and the continuity of production, but also the labor intensity of workers is high and the working environment is poor. In addition, in actual concrete production, there are also problems such as the change of raw materials due to changes in ambient temperature, which leads to temperature fluctuations at the concrete outlet, and the mixing time of the mixing plant is not easy to accurately control and mainly relies on manual estimation. Summary of the invention

[0004] In view of the above problems existing in the actual concrete production process, the utility model provides an integrated control system for the whole process of temperature-controlled concrete production, which brings all production links under unified computer monitoring; the system not only has a high degree of automation and stable and reliable operation, but also has better product quality and higher production efficiency.

[0081] The selection requirements for some key equipment of the system are as follows:

[0082] The host computer system gives priority to industrial computers and servers that are better adaptable to harsh environments. It can also use commercial machines with mainstream configurations to meet the needs of running related application software.

[0083] In terms of the number of interfaces on a Gigabit Ethernet switch, the number of electrical ports must be no less than 16, and the number of optical ports must be no less than 4.

If there are many on-site PLC stations at a long distance, the number of optical ports shall be increased accordingly.

[0086] The CPU and I / O modules of the local PLC system are mainly configured according to the scale of I / O control points in each link of concrete production. In terms of communication modules, each local PLC system is equipped with at least 2 RJ45 interfaces.

[0087] For local control systems without PLC, it is necessary to ensure that there is RS485 signal output, and the serial port server converts it into TCP / IP signal. If there is neither PLC nor RS485 signal output, it should be modified first and a PLC system should be installed.

[0088] In terms of concrete temperature control, the system adopts the collaboration of temperature control PLC and mixing plant PLC. The temperature control algorithm is implemented inside the temperature control PLC, and the ice and water adding processes are completed by the mixing plant PLC.

[0090] In terms of product concrete transport vehicle management, the utility model system implements ETC management for all concrete transport vehicles. Card readers are installed at the mixing plant entrance and exit as well as at the concrete pouring and unloading site. All concrete transport vehicles must be weighed twice in the automatic weighing room, with a heavy load and an empty load. Relevant data is entered into the system in real time. The MES system can query the vehicle's working status and the completion of the concrete production plan in real time.
