High-precision time relay and control method thereof

Abstract

The invention discloses a high-precision time relay and a control method thereof. The time relay sequentially comprises a power loop, a timing loop, an output loop, a delay specification setting loop, a delay range setting loop and a display loop, wherein the delay specification setting loop, the delay range setting loop and the display loop are connected with the timing loop; the delay specification setting loop comprises a plurality of first keys connected with a single chip microcomputer data port to achieve a plurality of time relays with different delay specifications; and the delay range setting loop comprises a plurality of second keys connected with the single chip microcomputer data port to achieve the time relays with different delay ranges under a single delay specification. The time relay comprises a plurality of delay model specifications; each model specification is also divided into a plurality of different delay ranges; and the delay ranges are switched through one or more dial switches. The delay time precision of the time relay does not need to be manually adjusted and the delay precision, accuracy and consistency are improved, so that the production efficiency is greatly improved; and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a high-precision time relay and a control method thereof. Background technique [0002] Most of the time relays produced by major manufacturers in the prior art are based on the improvement of the electronic time relay ST3P developed by Japan Fuji Electric Co., Ltd. This electronic time relay belongs to the RC oscillation time relay, and different delay specifications must be realized Delay capacitors with different capacities need to be used for rough adjustment, and after rough adjustment, manual fine-tuning of the delay accuracy is required. Therefore, the delay consistency of the electronic time relay is poor, and the electronic components and electronic component boards cannot be used for multi-standard time delays. The production process is cumbersome and the production efficiency is low. [0003] In order to meet the user's requirements for low cost, high relia...
