Problems solved by technology

[0003] 1. Because it adopts a centralized electrode changeover switch, not only the weight and volume of the changeover switch are huge, but also each acquisition terminal has one cable and ten electrodes. It is bulky and inconvenient to carry, and it is not easy to quickly survey under complex conditions;
[0004] 2. Its host can only store data, without its own processing function, it cannot be processed on site, which reduces work efficiency;
[0005] 3. The collected data is single and can only measure resistivity, which is not convenient for accurate comprehensive analysis of underground conditions

Embodiment Construction

[0021] It is composed of a host, electrodes, power supply and cables, and its features are:

[0022] 1. It also has a distributed electrode changeover switch, which connects several switches to each other in series through a series cable, see Figure 4 , 5 , Figure 5 The composite cable is 9 cores, A and B are power supply wire groups, M and N are measurement wire groups, that is, electrodes, 1 is the inner shielding layer, 2 is the outer shielding layer, 3 is the data communication twisted wire group, 4 is a switch power supply line group. In order to solve the problem of receiving the command signal sent by the instrument host and automatically selecting the address, an interface circuit for transmitting commands is designed. The circuit adopts the serial output mode. The host computer makes serial changes to the instructions through the interface circuit, and then the output circuit makes the level increase to form the DATA data stream, CLOCK clock and ENABLE function, ...

Abstract

A detector of crack opening or hole at shallow stratum is featured as applying distributed electrode change - over switch, using serial cable to connect those switches and to make them a string for combining switch box and cable to be an unified body, applying industrial control computer as a host, integrating the computer and collection motherboard to be unified body for not only storing data but also carrying out data processing and imaging on jobsite.

Description

technical field [0001] The invention relates to detection instruments for basic geological conditions, hidden dangers of underground buried engineering, and dangerous situations of dikes. Provide economical, rapid, accurate and reliable underground surveys for various engineering projects such as fortification engineering, civil air defense engineering, high-rise buildings, underground railways, expressways, bridge ports, airports, river embankments and dams. Background technique [0002] In the rapid development of national defense construction and national economic construction, the detection of basic geological conditions is the premise of various engineering constructions, and the discovery of hidden dangers is the key to disaster reduction and prevention. With the increasing number of various high-standard engineering projects such as fortification projects, civil air defense projects, high-rise buildings, underground railways, expressways, bridge ports, airports, emban...
