PLC wireless debugging device

Abstract

A PLC wireless debugging device comprises a PLC processor, a debugging upper computer, a first radio frequency (RF) transceiver, and a second RF transceiver, wherein the first RF transceiver is connected with the debugging upper computer, and the second RF transceiver is connected with the PLC processor; the first RF transceiver and the second RF transceiver each comprise a controller, a tunable oscillator, a mixer, an envelope detector, and a transceiving antenna; each controller is connected with the corresponding mixer and the corresponding tunable oscillator; each tunable oscillator is connected with the corresponding mixer; each transceiving antenna is connected with the corresponding mixer and the corresponding envelope detector; and each envelope detector is connected with the corresponding controller. The wireless debugging device provided by the invention has the advantages that communication connection between the debugging upper computer and the PLC processor is achieved through the RF transceivers, and the conventional technical means of using a router for the communication connection is replaced, so that communication connection settings are simple, the structure of the whole debugging device is simplified, power consumption for the communication connection is reduced, and the debugging communication quality is ensured.

Description

technical field [0001] The invention relates to a remote wireless debugging device suitable for a PLC processor. Background technique [0002] With the provision of modern automation control technology, the current large-scale manufacturing equipment has been equipped with electronic systems that can realize automatic production, and most of the electronic systems use PLC processors as the core. And as an essential link in the process of designing the system is to debug the system program. [0003] As we all know, the conventional debugging method is to use the wired online debugging method, that is, to use the data cable to connect the device to be debugged and the computer for data connection. In the debugging stage, wired debugging is very inconvenient. This is because the equipment to be debugged is generally placed in the workshop, and the production environment in the workshop is complicated. If wired connections are used in this environment, the debugging process wil...

[0003] As we all know, the conventional debugging method is to use the wired online debugging method, that is, to use the data cable to connect the device to be debugged and the computer for data connection. In the debugging stage, wired debugging is very inconvenient. This is because the equipment to be debugged is generally placed in the workshop, and the production environment in the workshop is complicated. If wired connections are used in this environment, the debugging process will appear very inconvenient

[0004] In view of the above situation, in the prior art, wireless routers are used as the communication connection medium between the underlying PLC processor and the debugging host computer, but in reality, the setting of the router is difficult and cumbersome, the setting cost is high, and the system structure is complex
