High-performance paperless recorder

Abstract

The invention discloses a high-performance paperless recorder which comprises a pressure sensor, a temperature sensor, a flow sensor, a humidity sensor and an amplifying circuit used for amplifying electrical signals output by above sensors. The high-performance paper recorder further comprises a filter circuit, an A / D switching circuit and a power module. The pressure sensor, the temperature sensor, the flow sensor and the humidity sensor are all connected with the amplifying circuit, the amplifying circuit is connected with the filter circuit, and the filter circuit is connected with the A / D switching circuit. The A / D switching circuit is connected with an optoelectronic isolation circuit which is connected with a single chip microcomputer, the input end of the single chip microcomputer is connected with a watchdog circuit, a clock circuit and a keyboard input module, the output end of the single chip microcomputer is connected with an LCD module and a memorizer, and the single chip microcomputer is in connection and communication with an upper computer through a serial communication circuit. The high-performance paperless recorder is reasonable in structural design, quick and sensitive, good in stability, high in real-time performance, good in anti-interference performance, and convenient to popularize and use.

Description

technical field [0001] The invention relates to a recorder, in particular to a high-performance paperless recorder. Background technique [0002] In the industry, it is often necessary to record temperature, pressure, flow and other information. Conventional analog recorders are being replaced by paperless recorders due to the shortcomings of less functions, single display, and need for recording pens. As a microprocessor as the core, set LCD Chinese characters and graphics display as one. Intelligent instruments with paperless records, good real-time performance, good versatility, high precision, and communication functions have a broad market. At present, many manufacturers are focusing on the color screen of the recorder, large-capacity storage: large-screen liquid crystal display and other functions; however, for users, the most concerned is the comprehensive performance of the instrument such as accuracy, reliability, applicability, and cost performance. Therefore, it...
