Problems solved by technology

Due to the limited diameter of particles that can be counted by the existing particle counting system, for example, only particles with diameters of 0.3 μm, 0.5 μm, 1.0 μm, 3.0 μm, and 10.0 μm can be counted, and the diameters of 0.4 μm and 0.45 μm cannot be counted according to user needs. μm, 0.6μm, 0.7μm particles, in addition, the existing particle technology system cannot detect whether the sensor (used to detect the size and number of particles) is working abnormally, so when the particle counting system is working and the sensor fails, The particle counting system will continue to perform particle counting, which reduces the accuracy of particle counting and reduces the user experience

Abstract

The invention discloses a particle counting system, method and device and a medium, the system comprises a sensor, an ADC connected with the sensor and an ASIC connected with the ADC, the ADC is used for converting analog signals which are collected by the sensor and represent the diameter and the number of particles into digital signals and sending the digital signals to the ASIC. And the ASIC is used for calculating the corresponding target particle number according to the digital signal and the target particle diameter corresponding to the user demand by using a particle algorithm under the condition of judging that the sensor does not have a fault according to the digital signal. The corresponding target particle number is calculated according to the target particle diameter, so that the problem that the particle number of the corresponding diameter cannot be counted according to user requirements in the prior art is solved; in addition, before the target particle number is calculated, whether the sensor has a fault or not is judged, the particle calculation accuracy is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of chip technology, in particular to a particle counting system, method and device. Background technique [0002] Particle counter is an instrument for measuring the number and particle size distribution of dust particles per unit volume in a clean environment. , pharmaceutical workshops, semiconductors, optical or precision machining, plastics, spray paint, hospitals, environmental protection, inspection institutes and other production enterprises and scientific research departments, used to test the cleanliness of the air in the production and experimental environments of pharmaceutical workshops, scientific research departments, etc., thereby reducing The problem of particle pollution during production and experimentation. [0003] At present, the particle counting system mainly uses a comparator to calculate the number of particles corresponding to each diameter by comparing the sizes of different parti...
