Abstract

The invention provides a programmable logic controller and a control system thereof. The controller comprises a Beidou receiving antenna, a variable-frequency amplifier, a Beidou RDSS (radio determination satellite service) chip, a data resolver and a data processor in sequential connection. The Beidou receiving antenna receives Beidou satellite signals from a control terminal; the variable-frequency amplifier performs amplification and frequency conversion on the satellite signals to obtain Beidou baseband signals; the Beidou RDSS chip performs analog-to-digital conversion and demodulation on the Beidou baseband signals to obtain baseband signal data; the data parser parses the baseband signal data and sends the parsed data to the data processor; the data processor carries out corresponding operations according to the parsed data. The PLC (programmable logic controller) which serves as a controlled device can operate by means of wireless control, line arrangement is avoided, and the defects of complexity in line arrangement and difficulty in line implementation in use of the PLC as the controlled device in wired control operation can be overcome.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a programmable logic controller and its control system. Background technique [0002] PLC (Programmable Logic Controller, Programmable Logic Controller), as an electronic device specially used in the field of industrial control, has been widely used due to its advantages of simple programming, powerful functions, strong adaptability, and high reliability. [0003] At present, as the controlled equipment, the existing PLC can only work in the way of wired control, specifically: control equipment such as industrial control computers, upper-level PLCs, etc. are wired with the current PLC through peripheral interfaces, and send work instructions to the current PLC , to control the current PLC work. [0004] As a controlled device, PLC works in a wired control mode, and needs to lay special communication lines, which has the disadvantages of complex line layout and difficult line...
