Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 The composition diagram of a "flipped classroom"-oriented PLC semi-physical classroom teaching experimental device is shown, including virtual controlled objects, physical PLCs, and programming / debugging computers.

[0022] The virtual controlled object includes a teacher's computer, a classroom projection system, and the I / O interface box of the controlled object; the teacher's computer is equipped with configuration software, which is appropriately simplified according to the actual shape of the controlled object, and is made by the configuration software. The controlled object model can control the virtual controlled object by changing the variable value in the model; the controlled object I / O interface box corresponds the variable in the model to the actual input and output signal circuit, so that the model can Pe...

Abstract

The invention designs a classroom teaching-oriented PLC (Programmable Logic Controller) HWIL (Hardware-in-the-Loop) experimental device in order to increase the classroom teaching effect of PLC lessons. The classroom teaching-oriented PLC HWIL experimental device comprises a virtual controlled object, an entity PLC and a programming / debugging computer, wherein the programming / debugging computer isconnected with a wireless signal of the entity PLC; the virtual controlled object comprises a teacher computer, a controlled object I / O (Input / Output) interface box and a classroom projection system;the teacher computer is equipped with configuration software; the configuration software contains a controlled object model; the teacher computer is connected with a wireless signal of the controlledobject I / O interface box; the controlled object I / O interface box is in hardware I / O wiring with the entity PLC. According to the classroom teaching-oriented PLC HWIL experimental device disclosed bythe invention, the problem that a traditional PLC experimental table is difficult to be used for classroom teaching is solved, and a satisfactory effect in teaching application is obtained.

Description

technical field [0001] The invention relates to a PLC experimental device, in particular to a classroom teaching-oriented PLC semi-physical experimental device. Background technique [0002] At present, many colleges and universities offer Programmable Logic Controller (PLC) courses, which require a close combination of theory and practice. One of the problems faced in course teaching is how to improve the practicality of classroom teaching. An effective way to solve this problem is to carry out theoretical and practical teaching in the classroom at the same time, so as to realize advanced cognition of theoretical knowledge in application, analysis, evaluation and creation. The traditional PLC experiment bench is difficult to apply to PLC classroom teaching due to its bulky size, single controlled object, and inability to connect to each student one-to-many. Therefore, colleges and universities urgently need a PLC experimental device suitable for classroom teaching to repl...
