Abstract

The invention provides a pressure detection and display alarm chip and system. The chip comprises an electric signal generation module which is used for collecting the pressure of a to-be-detected sample so as to convert the collected pressure into an electric signal, a data processing module which is connected to the electric signal generation module and is used for converting the electric signalinto a pressure signal, generating a high-pressure alarm signal when the pressure signal is greater than a reference high pressure, and generating a low-pressure alarm signal when the pressure signalis less than a reference low pressure, and a working voltage providing module which is connected to the data processing module and is used for providing a working voltage for the data processing module. With the pressure detection and display alarm chip and system, problems that the existing automobile pressure detection chip is single in function and needs to match a peripheral circuit to generate an alarm signal, and consequently the circuit structure is complex are solved.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a pressure detection and display alarm chip and system. Background technique [0002] Automobile oil pressure is an important diagnostic parameter of the engine lubrication system, and its size depends on the temperature and viscosity of the oil, the oil supply capacity of the oil pump, the adjustment of the pressure limiting valve, the resistance of the oil channel and the oil filter, and the crankshaft main bearing, Clearance of connecting rod bearings and camshaft bearings, etc. When the engine is running, the normal oil pressure must be maintained; if the oil pressure is too low, the friction surfaces will be aggravated due to insufficient lubrication; if the oil pressure is too high, it is easy to damage the oil seal and oil filter, and waste The power of the engine. [0003] Existing automotive pressure detection chips generally only perform pressure detection, so whe...
