[0002] With the development of technology, the technological level in the field of safety monitoring is also constantly improving. As a supplementary method to manual measurement means, the automated data acquisition system is widely used in engineering. The automated data acquisition system is a system that forms a network by combining safety monitoring instruments, automated data acquisition units, data transmission devices, and data receiving devices, so as to transmit the front-end monitoring data back to the rear for analysis.

[0003] At present, there is no dedicated artificial comparison interface for the dam safety monitoring automation system at home and abroad. The artificial comparison interface of some power stations measures through the acquisition module, which affects the authenticity of the measured values of the instruments. The existing artificial comparison transfer devices use plug-and-play interfaces for measurement, which greatly increases the labor cost. At the same time, wiring errors are likely to occur, and the synchronous transmission of signals of instruments such as vibrating wire and differential resistance cannot be achieved. Most of the existing artificial comparison transfer devices are arranged in outdoor equipment areas such as hydropower stations. When encountering lightning strikes outdoors, there is a lack of protection, which cannot ensure the accuracy of the measured values and is likely to affect the efficiency of artificial comparison.

[0024] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] See Figure 1-2 , the manual comparison transfer device for the safety monitoring automation system includes a comparison transfer box 1, a comparison transfer mechanism, a lightning protection mechanism and a connection mechanism, and the comparison transfer mechanism, the lightning protection mechanism and the connection mechanism are arranged in the comparison transfer box 1.

[0026] The comparison transfer mechanism includes a wire board 2, a terminal block interface 3, a terminal seat 4, a comparison rotating shaft 5, a comparison spring piece 6 and a comparison knob 7. The wire board 2 is fixedly installed in the comparison transfer box 1, the terminal block interface 3 is fixedly arranged on the wire board 2, and the outside of the terminal block interface 3 passes through the comparison transfer box 1 and is electrically connected to the original internal observation monitoring acquisition sensor 15. A terminal seat 4 is fixedly arranged in the middle on one side of the wire board 2, a comparison rotating shaft 5 is rotatably arranged on the other side of the wire board 2, the comparison rotating shaft 5 is arranged at the end of the terminal seat 4, a comparison spring piece 6 is fixedly arranged on the comparison rotating shaft 5, and a comparison knob 7 is fixedly installed on the other side of the comparison rotating shaft 5 through the comparison transfer box 1.

[0027] During operation, the signals of the original internal observation monitoring acquisition sensor 15 are sorted by channels and physically connected to the terminal block interface 3 to realize the synchronous transmission of signals of instruments such as vibrating wire and differential resistance. By rotating the comparison knob 7 to drive the comparison rotating shaft 5 and the comparison spring piece 6 to rotate inside the comparison transfer, the signals of the corresponding channels are transmitted to the output connection mechanism one by one, and the signals such as vibrating wire and differential resistance of the selected channels are output through the connection mechanism.

[0028] In some embodiments, the lightning protection mechanism includes a lightning protection channel 10 and a lightning protection cable 11. A lightning protection channel 10 is provided in the comparison measurement adapter box 1, and a lightning protection cable 11 is passed through the lightning protection channel 10. Two ends of the lightning protection cable 11 are electrically connected to a terminal block interface 3 and a terminal seat 4 respectively.

[0029] During operation, a lightning protection is formed through the lightning protection channel 10 and the lightning protection cable 11, effectively ensuring the accuracy of the measured value and greatly improving the manual comparison measurement efficiency.

[0031] During operation, analog multi-channel signals are output to an external detection instrument through the collection interface 12 and the collection cable 14 for convenient reading of values. By rotating the comparison measurement knob 7, the comparison measurement rotating shaft 5 and the comparison measurement elastic piece 6 are rotated in the comparison measurement adapter box, and signals of corresponding channels are transmitted to the output collection interface 12 one by one, so that signals such as vibrating wire and differential resistance of the selected channels are output through the collection interface 12.

During the transmission process, the lightning protection channel 10 and the lightning protection cable 11 reduce the risk of the instrument being damaged by lightning strikes. By rotating the comparison measurement knob 7, the comparison measurement rotating shaft 5 and the comparison measurement elastic piece 6 are rotated in the comparison measurement adapter box 1 to manually switch analog quantities, and signals of corresponding channels are transmitted to the collection interface 12 one by one, and then output to an external detection instrument through the collection cable 14 for measurement.
