Description

Technical Field

[0001] The utility model belongs to the technical field of circuits, and in particular relates to a storage value updating circuit for a force sensitive sensor. Background Art

[0002] When the product is delivered to the customer, the output value of the force-sensitive sensor without human operating force is collected as the initial force value, and the initial force value is stored in the storage circuit of the product. Each subsequent operation of the product is based on the force value in the storage circuit for related processing operations. Due to differences in the process level, installation location and operating conditions of the sensor installers, the actual initial force value of the force-sensitive sensor will change with the increase in usage time, which is inconsistent with the force value stored in the storage circuit. At this time, it is necessary to update the initial force value stored in the storage circuit in a timely manner according to the actual situation. Otherwise, product processing will bring a series of errors, and the later maintenance of the product will be more troublesome, resulting in the product being difficult to upgrade and maintain in subsequent use, and the problem of not being able to adapt to the product installation situation well, making the product inconvenient to use in the later period.
