Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0014] The purpose of the embodiments of the present invention is to provide a pressure recorder suitable for pressure measurement when unattended.

[0015] figure 1 A structure of the above-mentioned pressure recorder is shown, including a waterproof casing 1 (its protection level can reach IP68, so it is suitable for harsh pressure measurement environments such as underground), and a pressure sensor 2, a memory chip 3, and a collection chip are arranged in the ca...

Abstract

The embodiment of the invention discloses a pressure recorder which comprises a waterproof case. A pressure sensor, a collection unit, a storage chip, a power supply unit and a central processing unit are arranged in the case, and the central processing unit comprises a micro-control unit and a real-time clock, wherein the real-time clock is used for awaking the micro-control unit in a timing way through a monitoring circuit, and the power supply unit is used for receiving instructions from the awoken micro-control unit, and respectively supplying power to the collection unit and the storage chip. It is observed that the storage chip can be used for storing collected data without manual recording, therefore the pressure recorder is suitable for pressure measurement without anybody watching; however, after the micro-control unit is awoken, the collection unit, and the like can be supplied with the power, therefore each unit is in a operating state periodically or intermittently, and power consumption is reduced so as to ensure that the whole recorder can operate for a long time.

Description

technical field [0001] The present invention relates to the technical field of pressure measurement, more specifically, to a pressure recorder. Background technique [0002] Most of the traditional pressure measuring instruments measure the pressure through the elastic deformation of the elastic sensitive element with the change of the pressure. They do not have the recording function and cannot meet the requirements of pressure measurement when unattended. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a pressure recorder suitable for pressure measurement when unattended. [0004] In order to achieve the above purpose, embodiments of the present invention provide the following technical solutions: [0005] A pressure recorder, comprising a waterproof casing, the casing is provided with: a pressure sensor, an acquisition unit, a memory chip, a power supply unit and a central processing unit, the ce...
