In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail. Furthermore, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.

101. detecting the total thickness and the total weight of paper money in the paper money box;
and after receiving the banknote box, the terminal equipment detects the total thickness and the total weight of the banknotes in the banknote box. Specifically, the total thickness of the banknotes can be detected by lifting and lowering a banknote placing table in the banknote box for multiple times, measuring the movable space (measured by the length) of the placing table, and subtracting the movable space of the placing table from the total length of the hollow part of the banknote box, so that the total thickness of the banknotes in the banknote box is obtained. The way of detecting the total weight of the paper money can be as follows: a certain number of weighing chips are arranged on a placing table used for bearing paper money in a paper money box, the weighing chips are used for measuring the total weight of the paper money in the paper money box, and the high-precision weighing chips are adopted, so that the weight of the paper money can be conveniently and accurately measured. It should be noted that, in addition to the above-listed thickness (weight) measuring methods, other various known thickness (weight) measuring methods can be adopted in the present application.
102. And calculating to obtain the number of the paper money in the paper money box according to the total thickness, the total weight, the thickness of a single paper money and the weight of the single paper money.
After the total thickness and the total weight of the paper money in the paper money box are detected, the known parameters such as the thickness of a single piece of paper money and the weight of a single piece of paper money can be combined for fusion calculation to obtain the number of the paper money in the paper money box.

209. Determining the second number of paper money as the number of paper money in the paper money box;
if the absolute value of the second error is smaller, which indicates that the error of the number of banknotes obtained by the weighing method is smaller, the result of the number of banknotes obtained by the weighing method (i.e., the second number of banknotes) is used as the final result.
210. And determining the first number of paper money as the number of paper money in the paper money box.
If the absolute value of the first error is small, which indicates that the error of the number of banknotes obtained by the thickness measurement method is small, the result of the number of banknotes obtained by the thickness measurement method (i.e., the first number of banknotes) is used as a final result.
