Pulse detection device and pulse detection method

Abstract

The invention provides a pulse detection device and a pulse detection method, which are applied to a pulse detection system and belong to the technical field of signal detection equipment. The pulse detection system comprises a reference clock source and a signal source to be detected. The pulse detection device comprises a first input device, a second input device and a counting processing device, wherein the first input device is coupled to the signal source to be detected, the second input device is coupled to the reference clock source, both the first input device and the second input device are coupled to the counting processing device, and the counting processing device is coupled to a control end of the second input device. In the detection process, the counting processing device controls starting and ending of the detection process through detecting the level of the clock signal to be detected, thereby ensuring the length of detection time to be matched with the clock signal to be detected, and thus greatly improving the detection accuracy. Furthermore, the whole detection process realizes automatic control through the counting processing device, so that the detection process is enabled to be simple and easy to operate, and the convenience and the applicability are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of signal detection equipment, in particular to a pulse detection device and a pulse detection method. Background technique [0002] With the development and improvement of science and technology, the State Grid has set higher requirements for the clock accuracy of smart meters. Therefore, it is necessary to detect the smart meter. [0003] In the prior art, the clock accuracy of the smart meter can be detected by counting coincident pulses. Although the detection accuracy of the coincidence pulse counting method is high, the circuit of the coincidence pulse counting is complex, resulting in high production costs, and the operation steps of the coincidence pulse counting are cumbersome, which seriously affects the convenience and applicability of its actual use. In addition, the clock accuracy of the smart meter can also be obtained by comparing the clock signal of the smart meter to be detected wi...

Problems solved by technology

However, in this detection technology, it is difficult to accurately determine the start time and end time point of detection through this technology, which leads to errors in the detection time and seriously affects the accuracy of detection; the operation steps of this detection technology are also very cumbersome. The steps are cumbersome, resulting in a low fault tolerance rate for inspectors, which is prone to operating errors and seriously affects the accuracy of detection; at the same time, the cumbersome steps of the operation also seriously affect the applicability of its actual use
