Embodiment Construction

[0018] see Figure 5 , the wiring detection system of the present invention includes a single-chip computer serially connected to a computer, and the single-chip computer and the main computer exchange commands and data through serial communication, and adopt A / D converter multi-way cards and MAX232 to realize the connection between RS232 and TTL levels. mutual conversion. SCM circuit I / O line, used to connect with the analog wiring board. The single-chip microcomputer is connected with an address latch and a data bus driver, and the address latch is connected with a gate circuit and a decoder, and the system uses the decoder to perform address decoding and is used for gating each chip latch. The data bus needs to add a bus driver to increase the load capacity of the bus. Gate circuits, decoders and data bus drivers are connected to wiring boards through bidirectional data latches. Because a connection point can be both a starting node and an ending node, the I / O line shoul...

Abstract

The invention provides a wiring detection system and a wiring detection method. The wiring detection system comprises a singlechip which is connected in series with a computer and is connected with an address latch and a data bus driver, the address latch is connected with a gate circuit and an encoder, and the gate circuit, the encoder and the data bus driver are connected with a wiring board by a bidirectional data latch. The wiring detection method serially reads a wiring scheme, outputs start node numbers according to the wiring scheme, sends out test electric signals for wiring operation, reads a terminal node state, judges and detects whether connection is finished or not and displays a result according to a finishing situation so as to realize the detection of the wiring connection. The invention can realize the high-efficiency production, decreases the production cost, can lower the quality requirements of operators, saves the labor cost, does not need complex professional training, saves the educational training cost and working hour, reduces tool equipment modification cost, lessens wiring errors and improves the production qualified rate and the product quality.

Description

【Technical field】 [0001] The invention relates to the fields of electromechanical and communication manufacturing, in particular to a detection system and a detection method in the production process. 【Background technique】 [0002] In the process of product production, there will always be defective products due to various reasons. In the process of elevator manufacturing, wiring operation is a rigorous and complicated process. If there is an operation error, the entire wiring will fail to operate. The last link in the process is to inspect the wiring to prevent problematic products from flowing out of the market and to detect and correct problems in the production process in a timely manner. For traditional operations see figure 1 As shown, the wiring of the reserved test terminals will be done first. In the figure, W3W, WC1, WB1, etc. are the wiring terminals of the wiring harness. 1:1 assembly position of terminals. On the LCD screen of the computer, the guiding wirin...
