Embodiment Construction

[0040] Such as figure 1As shown, the touch-screen batching control system of the concrete batching plant includes a host computer for setting and sending formula data and production parameter information required for batching. The host computer is composed of a main control industrial computer and an auxiliary control touch screen; The weighing sensor is used to detect the weight of raw materials sent from each raw material bin to the corresponding metering bin and generate real-time sending of raw material information; it is connected to the upper computer and the weighing sensor respectively, and is used to receive the information sent by the upper computer and the weighing sensor The PLC programmable controller that issues control instructions after logical judgment; is connected to the PLC programmable controller and the execution components in the concrete mixing plant respectively, and is used to execute the PLC programmable controller. The intermediate relay of the contr...

Abstract

The invention relates to a touch screen type batching control method and system for a concrete batching plant. The touch screen type batching control method and system for the concrete batching plant solve the problems that according to an existing automatic batching method and system, since control and operation are centralized, the requirement for the reliability of communication is high, and the real-time control effect is poor. According to the touch screen type batching control method and system for the concrete batching plant, a PLC which is connected with a master control industrial personal computer and an auxiliary control touch screen through communication cables is started; the PLC conducts output control over a plurality of intermediate relays, so that control instructions are sent to all execution components in the concrete batching plant, and therefore each execution component conducts motion according to the production parameters set by an upper computer. In this way, the stability and the accuracy of an automatic batching system are improved, the reliability and the real-time performance of communication are improved, centralized operation, centralized monitoring, centralized management and decentralized control of the production process are achieved, the production flow of the concrete batching plant can be automatically controlled and monitored, and data management of concrete production can also be achieved.

Description

technical field [0001] The invention relates to an automatic batching control method and system, in particular to a touch-screen batching control method and system for a concrete mixing plant. Background technique [0002] At present, my country's concrete mixing plants are developing in the direction of intelligence, environmental protection, high precision, standardization, localization, small and medium-sized, and popularization, so the research on control technology of concrete mixing plants has broad application prospects and important scientific value. The batching process of the concrete batching plant runs at high speed in a dynamic process. In order to ensure the batching accuracy, it is necessary to improve the real-time performance of the batching process. The control system of the existing concrete mixing plant mostly adopts the control method of "industrial computer + intelligent batching instrument + programmable logic controller PLC" or the control method of "...
