The working process of the embodiment is as follows:
as shown in fig. 3, the present embodiment is applicable to both the reticle sorting and the reticle hunting.
The sequencing functional principle is as follows: according to a communication protocol established between the host end A and the hunting end B, when the cable is not accessed, the communication fails, and the cable is considered to be broken. After the cable is connected, the host computer end A can know the on-off and sequencing type of the cable in a digital communication mode between the host computer end A and the line searching end B. Meanwhile, the host end A also sends data to the line searching end B, so that the line searching end B also knows the on-off and sequencing type of the cable.
In this embodiment, the timing of the timers in the host-side integrated control unit a3 and the line-searching-end integrated control unit B4 and the specific pins of the CPU are controlled by a program algorithm and a communication protocol, so that the communication between the host-side a and the line-searching-end B is scheduled and controlled and the time-sharing multiplexing is realized. The hunting audio signal is unicast without subsequent; the network cable ordering is communicated bi-directionally. The hunting function is a main process (occupying more CPU time), and the network cable sequencing function is a secondary process (occupying less CPU time, namely, the gap time).
The line hunting functional principle: the host end A sends specific frequency waves to a cable needing to be searched, and the line searching end B detects the specific frequency waves on the cable, so that the cable is considered as the cable needing to be searched, and generates a voice prompt to search a target cable; and simultaneously, according to the detected different signal intensities, indicator lights with different intensities are generated.
As shown in fig. 4, the host a sends out the hunting audio signal (generated by the hunting signal modulation generator a31) by default, and continuously sends out the net ordering signal by the net ordering detecting unit a32 with the gap time to detect whether the net end is accessed to the net ordering port. If the tail end of the network cable is not accessed to the line searching end B, namely the line searching end B does not return a signal to the network cable sorting detection unit A32, continuously sending a line searching audio signal and detecting the state of the network cable by utilizing the gap time; if the tail end of the network cable is connected with a line searching end B (a signal is returned by the line searching end B), the host end A automatically switches to a network cable sorting mode, establishes communication with the line searching end B and exchanges information through a digital signal with codes.
In the network cable sorting mode, the network cable sorting detection unit a32 detects the strip coded data signal of each pin of the network port to know the network cable sorting status (hundreds of megabytes or gigabytes, direct network cables, cross network cables or other types), and sends the status to the line searching terminal B. After the network cable sorting is completed, the state of the on-off end of the crystal head is detected by the crystal head on-off end detection unit A33, which network cable is disconnected is known by sorting, and then the disconnected network cable is pulsed to detect whether the crystal heads at the two ends of the network cable are disconnected at the near end or the far end or the middle of the network cable and display (see figure 5). The detection result is then also sent to the hunt port B share.
As shown in fig. 6, the hunting terminal B mainly operates to detect the hunting audio signal of the host terminal a when the hunting terminal B does not detect the network cable sequencing signal sent by the host terminal a. When the hunting audio signal is detected, the hunting end display unit B2 displays or the hunting end sound unit B3 indicates by sound and light alarm and intensity. When the network cable sorting receiving unit B42 detects a network cable sorting signal sent by the host a, the hunting terminal B automatically switches to the network cable sorting mode, and interacts information with the host a through the coded digital signal to obtain the detection result of the host a.
