Embodiment 1
[0017] Embodiment 1. An online calibration system for gas dispensers based on a hand-held calibration device. Combine below figure 1 The system provided in this embodiment will be described in detail.
[0018] see figure 1 , the system provided in this embodiment includes a hand-held calibration device and an air dispenser electrically connected to the hand-held calibration device. In this embodiment, the displayed gas filling capacity of the dispenser (i.e. the standard gas filling capacity measured by the gas dispenser) and the standard gas filling capacity can be expressed by a functional relationship: standard gas filling capacity = K * display gas filling Quantity + A, among them, K>0, K is called the correction coefficient, and A is called the compensation coefficient. When there is an error between the displayed gas volume of the gas dispenser and the standard gas volume, the hand-held calibration device sets calibration parameters on it, wherein the calibration para...
Embodiment 2
[0022] Embodiment 2. An online calibration method for gas dispensers based on a hand-held calibration device. Combine below figure 2 The method provided in this embodiment will be described in detail.
[0023] see figure 2 , S201. When there is an error between the displayed gas volume of the gas dispenser and the standard gas volume, the hand-held calibration device sets calibration parameters and transmits the calibration parameters to the main control board of the gas dispenser.
[0024] Specifically, when there is an error between the displayed gas filling amount of the gas dispenser and the standard gas filling amount, the hand-held calibration device sets calibration parameters on it, wherein the calibration parameters in this embodiment mainly include calibration coefficients and compensation coefficients , and transmit the set correction parameters to the main control board of the dispenser. It should be noted that, in order to ensure the safety of the handheld ca...
