Abstract

The invention relates to an anti-intensive-impact and high-voltage-resistant temperature pressure sensor combined device comprising a temperature sensor, a pressure sensor, a temperature-and-pressure-sensor-based DSP detection system, and a direct-current voltage-stabilizing power supply. The temperature-and-pressure-sensor-based DSP detection system includes a box body and a DSP detection unit circuit; and the DSP detection unit circuit is arranged in the box body. The DSP detection circuit consists of a data processing chip, a temperature sensor interface circuit, a pressure sensor interface circuit, a CAN bus communication interface circuit, an acousto-optic alarm circuit and a direct-current power supply module; and the direct-current power supply module is respectively connected with voltage input interfaces of a DSP minimum system, the temperature sensor interface circuit, the pressure sensor interface circuit, the CAN bus communication interface circuit, and the acousto-optic alarm circuit and provides a direct-current power supply for the above-mentioned units. According to the invention, the temperature and pressure that are changed dynamically can be measured with high speeds; the reliability and continuity are high; and the measurement precision is also high.

Description

technical field [0001] The invention relates to the technical field of sensors, and more specifically relates to a temperature and pressure sensor capable of resisting strong shock and high pressure and a detection unit thereof. Background technique [0002] Traditional industrial pressure sensors for hydraulic pressure and air pressure measurement and industrial temperature sensors for liquid temperature measurement are often used under conventional vibration shock conditions and low working pressure conditions, and it is difficult to withstand strong shock vibration (≦200g) and strong pulse pressure (≦20MPa), in extreme cases, the sensor may even be permanently damaged. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a combination of temperature and pressure sensors that are resistant to strong shocks and high pressures. The present invention can measure high-speed changes in temperatu...
