Slave station address detection device and slave station equipment

Abstract

The slave station address detection device comprises a processor of a slave station, N groups of * A first pin headers, N groups of * A second pin headers, a first short circuit cap and a second short circuit cap, N is greater than or equal to 1 and less than or equal to 2, A is greater than 2 and less than 10, and N * A is a positive integer which is not greater than 10; the processor sequentially outputs a first detection level to the j detection signal input end, detects the first signal detection end to the A signal detection end, and determines a ten-bit numerical value based on the signal detection end outputting the first detection level; a second detection level is sequentially output to the kth detection signal input end, the first signal detection end to the Ath signal detection end are detected, the unit numerical value is determined based on the signal detection end outputting the second detection level, a dial switch and a knob switch do not need to be arranged, the cost is reduced, in addition, the address of the slave station can be determined only by detecting 2N + A detection signals, and the detection efficiency is improved. And the signal detection quantity is relatively small.

Description

technical field [0001] The invention relates to the field of signal detection, in particular to a slave station address detection device and slave station equipment. Background technique [0002] The fieldbus control system includes a master station and multiple slave stations. When the master station sends a signal to communicate with a slave station with a certain address, the multiple slave stations will detect their own addresses through their own processors. When the address of the slave station is consistent with the address of the slave station required by the master station, the slave station can realize the communication with the master station. In the prior art, the processor of the slave station detects the address of the slave station by detecting the state of the dial switch or the rotary switch, but the cost of the dial switch or the rotary switch is relatively high. In addition, when it is necessary to detect 100 addresses of the slave station, the processor ...

AI Technical Summary

Problems solved by technology

In the prior art, the processor of the slave station realizes the detection of the address of the slave station by detecting the state of the dial switch or the rotary switch, but the cost of the dial switch or the rotary switch is relatively high

In addition, when it is necessary to detect 100 kinds of addresses of the slave station, the processor needs to detect 20 detection signals of two 10-bit DIP switches, and the amount of detection signals is relatively large.
