Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of an embodiment of a communication middleware-based VTM device communication method provided by the present invention. In this example, the method:

[0039] The communication middleware receives demand instructions from the application side through a preset public interface, and invokes the corresponding driver from the preset bottom dynamic library according to the received demand instructions; that is, through the hardware interface specification, the bottom dynamic library is defined as A set of Java Script classes for application development, which uses ActiveX controls to package the underlying API, and then encapsulates the ActiveX controls into Java Script classes (that is, the JS midd...

Abstract

The invention provides a VTM equipment communication method and system based on communication middleware, and the method comprises the steps: the communication middleware receives a demand instruction of an application end through a preset public interface, and calls a corresponding drive from a preset bottom-layer dynamic library according to the received demand instruction; the communication middleware executes operation on the corresponding VTM equipment through the called drive to obtain an execution result; and the communication middleware judges whether the communication is successful or not according to the obtained execution result, so that the communication between the application end and the VTM equipment is realized. According to the method, a unified channel and a unified access specification of the equipment driver and the business application platform are established, cross-language calling is realized, a calling interface is simplified, and the complexity of business operation and equipment interaction is shielded.

Description

technical field [0001] The invention relates to the technical field of VTM equipment communication, in particular to a communication middleware-based VTM equipment communication method and system. Background technique [0002] With the construction of smart business halls, many simple businesses with a large workload can be handled through self-service, without the need for manual counters. At the same time, through the construction of the smart device network information service platform, the working mode of the Nanshan smart business hall has a high degree of scalability, especially the smart devices have the conditions for rapid procurement and promotion. With the increasing number of smart devices, in order to ensure the standardization of smart device access, improve the management of smart devices, and reduce the cost of smart device operation and maintenance. In this context, it is imminent to establish a unified smart device access standard. [0003] In particular,...
