Abstract

The invention relates to a signal collection terminal. The signal collection terminal comprises a processor, a signal collection interface, an RS-485 communication interface and an RS-232 communication interface, wherein the signal collection interface is connected to an I / O (input / output) port of the processor; the RS-485 communication interface is connected to a second UART (universal asynchronous receiver transmitter) of the processor; the RS-232 communication interface is connected to a third UART of the processor. The invention further discloses a test box data collection system. The system uses a plurality of signal collection terminals, each signal collection terminal is correspondingly connected with one test box, the signal collection interfaces and RS-232 communication interfaces of the signal collection terminals are connected to the test boxes, and the RS-485 communication interfaces are connected to an RS-485 network. The test box data collection system disclosed by the invention can perform equipment networking and centralized display and control of the test boxes of different manufacturers, is combined with a large screen for display, and can perform early warning and alarm on key operation indexes of the test boxes so as to greatly reduce the working strength of staff on duty.

Description

technical field [0001] The present invention relates to a collection device for industrial control equipment, in particular to a signal collection terminal using RS-485 network communication; the present invention also relates to a test box data collection system using the aforementioned signal collection terminal. Background technique [0002] In the environmental and reliability testing of electromechanical equipment, aging testing of electronic components, and electromagnetic compatibility testing, the equipment under test needs to run in the test chamber for different periods according to the requirements of the test program. During the test period, the operating status of each test chamber needs to be regularly inspected and recorded manually, and it is also necessary to intervene in sudden emergencies. This mode of work requires one-on-one responsibility of a dedicated person and a special box, which can meet the situation of few test tasks and a small number of test b...
