Apparatus for realizing automatic channel switching control of large dam monitoring apparatus collective line box and method thereof

Abstract

The invention relates to an apparatus for realizing automatic channel switching control of a large dam monitoring apparatus collective line box and a method thereof. The apparatus comprises the large dam monitoring apparatus collective line box, a collective line box controller and a communication cable. The collective line box controller comprises a power carrier wave signal generator and a microcontroller which are mutually connected. The power carrier wave signal generator is connected with a first communication interface. The microcontroller is connected with a display device, an operation instruction input device and a power supply interface. The large dam monitoring apparatus collective line box comprises a second communication interface, a power carrier wave decoding circuit, a channel selection control circuit and a relay array which are connected in order. The relay array is provided with a safety monitoring apparatus interface array and a safety monitoring apparatus core wire bus interface. The apparatus also comprises a power taking circuit. The communication cable is connected with the first communication interface and the second communication interface. According to the apparatus and the method, the large dam monitoring apparatus collective line box realizes passivity work and automatic channel switching control, and the apparatus and the method have very practical meaning to realization of large dam safety monitoring in a construction period.

Description

technical field [0001] The invention relates to the technical field of safety monitoring of dams and geotechnical engineering, in particular to a device and method for realizing passive automatic channel switching control of a junction box of a dam monitoring instrument. Background technique [0002] In the field of safety monitoring technology for dams and geotechnical engineering, dam monitoring instrument junction boxes are indispensable and important equipment, especially during the construction period. Considering various factors such as structural strength, waterproof sealing, power supply difficulties, etc., manual control junction boxes are basically used at present. slope) is an inconvenient task. CN101651472A is the background technology of this application. Although there are already some junction box automation products for dam monitoring instruments, they all require constant power supply, such as figure 1 A structure block diagram of an existing dam monito...
