Abstract

The invention relates to the technical field of monitoring systems, in particular to a hardware overvoltage protection system which comprises a pressure detection module, a comparison module, a buzzing alarm module and a power supply control module. The pressure detection module collects pressure signals and amplifies weak pressure signals, and the comparison module compares the collected signals with threshold voltage of hardware design and outputs logic signals to control the buzzing alarm module and the power supply control module when the collected signals are larger than the threshold voltage. After receiving the signal, the buzzing alarm module gives out buzzing alarm sound to prompt a user that the user is in an overpressure state at present, the user or medical staff can still be prompted in time under the condition of software failure, meanwhile, the power supply control module powers off a pump valve of the pressure treatment equipment, air pressure can be released from a normally-open valve of the pressure treatment equipment at the moment, and the pressure treatment equipment is in an overpressure state. No matter whether software fails or not, no overvoltage can be ensured, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of monitoring systems, in particular to a hardware overvoltage protection system. Background technique [0002] The pressure therapy system uses an air pump to inflate, squeeze, and deflate the cavity air bag in an orderly and rhythmic manner, and uses intermittent pneumatic pressure to form a circulatory pressure from the distal end of the limb to the proximal limb tissue. After pressure is applied, the pressure is relieved, which promotes the return of venous blood and lymph, and helps prevent the formation of deep vein thrombosis; the existing pressure therapy equipment on the market mostly uses a pressure sensor for each channel as pressure feedback, and the pressure is collected by the sensor. After the signal is amplified and filtered, it is handed over to the processor for calculation and controls the pump valve to inflate and deflate the air bag to achieve the purpose of treatment. Most of the existi...
