Problems solved by technology

At present, there are mainly the following methods for the control system of the mixing building (station): 1. The "batching controller + PLC + PC" control system has the disadvantage that the batching controller has certain limitations in completing the batching measurement, and it does not have Buckle weighing function, single overshoot control method, closed software and hardware, limited resources and functions, slow parameter setting and data recording speed, low reliability, etc.
2. The "board card + PC" control system (IPC) has the disadvantages of poor vibration resistance, shock resistance, and moisture resistance in terms of hardware and inconvenient maintenance, and there is no strong real-time operating system and deterministic control in terms of software. , easy to crash, etc.
3. The "PLC+PC" control system has the disadvantages of poor openness, weak communicatio

Abstract

The invention discloses a stirring building or station embedded control system, which comprises an embedded industrial controller, wherein the communication interface of the embedded industrial controller is in communication connection with a display, an upper computer and an industrial Ethernet switch; the communication interface of the industrial Ethernet switch is connected with an input/output (I/O) controller; the signal input interface of the I/O controller is connected with the signal output end of a weighing sensor through an analog input module, and is in signal connection with a field switch through an on-off input module and an intermediate relay; the signal output interface of the I/O controller is connected with the control end of a field execution element through an on-off output module and an intermediate relay; the signal input end of the industrial Ethernet switch is connected with the signal output ends of a temperature detector, a slump detection device, a level sensor and a sand water measuring instrument; and the control output end of the industrial Ethernet switch is connected with the control input ends of a printer and a large display screen. The system has the advantage of realizing production automation of proportioning, unloading and concrete discharge in a stirring machine.

Description

technical field [0001] The invention relates to a mixing building and a station control system, in particular to an embedded control system of the mixing building and the station. Background technique [0002] In the construction of infrastructure such as water conservancy, energy, transportation, and construction, a large amount of high-quality concrete is required, and the production of concrete is inseparable from concrete mixing equipment. Therefore, the control accuracy, reliability and safety of the mixing plant (station) control system will directly affect the quality and efficiency of concrete production. At present, there are mainly the following methods for the control system of the mixing building (station): 1. The control system of "batching controller + PLC + PC" has the disadvantage that the batching controller has certain limitations in completing the batching measurement, and it does not have the Deduction function, single overshoot control method, closed so...
