复点机电气系统工作原理：当复点机电源开关打开后，需复点纸币或票据放在夹钞板上，同时触动启动开关，中央控制器CPU检测到启动开关信号打开气泵电机M3，使气泵电机工作同时使夹钞电机M1工作，当夹钞电机转动到一定位置时触动行程开关，当中央控制器CPU检测到行程开关信号，控制夹钞电机M1停止工作，从而使纸币进入被复点位置，同时中央控制器CPU控制吸引头电机M2工作，吸引头电机M2工作带动吸引头旋转，对纸币进行复点，复点过程中压力传感器检测吸引头内压力变化，判断纸币是否被吸引头吸引，从而对纸币进行点数，点数的数字通过显示部分的数码管LED进行显示。当用户在点钞过程中要急停时触摸急停开关可中断点钞过程。急停开关还具有保护作用，防止操作者手指被夹钞板夹住。用户需要确定数目点钞时，即可使用预置点钞功能，用户事先通过键盘输入预置点钞数，当点钞到预置点钞数目时中央控制器CPU控制电磁铁工作，电磁铁吸合后，将预置点钞数目与其他纸币分开，同时控制吸引头电机M2停止工作。当点钞完毕后，压力传感器检测到若干个没有纸币被吸合造成压力变动信号，中央控制器CPU控制吸引头电机M2停止旋转，同时中央控制器CPU控制夹钞电机M1旋转复位停止工作。The working principle of the electrical system of the multi-counter: when the power switch of the multi-counter is turned on, the banknotes or receipts to be double-counted are placed on the banknote clipping board, and the start switch is touched at the same time. The central controller CPU detects the signal of the start switch and turns on the air pump motor M3, so that The air pump motor works at the same time to make the banknote clamping motor M1 work. When the banknote clamping motor rotates to a certain position, the travel switch is touched. When the central controller CPU detects the travel switch signal, it controls the banknote clamping motor M1 to stop working, so that the banknotes enter the counter. At the same time, the central controller CPU controls the suction head motor M2 to work, and the suction head motor M2 works to drive the suction head to rotate to perform recounting on banknotes. During the recounting process, the pressure sensor detects pressure changes in the suction head to determine whether the banknotes are attracted by the suction head. , so that the banknotes are counted, and the number of points is displayed through the digital tube LED of the display part. When the user wants to make an emergency stop during the banknote counting process, touching the emergency stop switch can interrupt the banknote counting process. The emergency stop switch also has a protective function to prevent the operator's fingers from being caught by the note clamping plate. When the user needs to determine the number of banknotes to be counted, the preset banknote counting function can be used. The user inputs the preset banknote counting number through the keyboard in advance. After closing, separate the preset counting number from other banknotes, and simultaneously control the suction head motor M2 to stop working. After counting banknotes, the pressure sensor detects that a number of banknotes are not attracted to cause pressure fluctuation signals. The central controller CPU controls the suction head motor M2 to stop rotating, and the central controller CPU controls the banknote clamping motor M1 to rotate and reset to stop working.

当点钞完毕后中央控制器CPU控制吸引头电机M2旋转与霍尔元件的信号进行重新定位，为下次复点纸币做准备。After the banknote counting is completed, the central controller CPU controls the rotation of the suction head motor M2 and the signal of the Hall element to reposition, so as to prepare for the next counting of banknotes.

2、压力传感器模拟信号经过中央控制器CPU内部AD转换成数字信号，以便检测吸引头内部的压力变化，对纸币进行计数，同时还可以对吸引头电机转速进行调整。2. The analog signal of the pressure sensor is converted into a digital signal through the AD of the central controller CPU, so as to detect the pressure change inside the suction head, count the banknotes, and adjust the speed of the suction head motor at the same time.

3、霍尔元件构成的吸引头定位机构，机构简单定位准确。3. The suction head positioning mechanism composed of Hall elements is simple and accurate in positioning.

5、复点机电气系统由于采用了压力检测、数字量处理和吸引头电机可调速控制，可以克服由于气泵长期使用机械磨损造成压力变化对点钞影响，同时还可以克服不同区域使用大气压变化造成吸引头吸引力变化对点钞精度影响。5. The electrical system of the multipoint machine adopts pressure detection, digital quantity processing and adjustable speed control of the suction head motor, which can overcome the impact of pressure changes on banknote counting caused by long-term mechanical wear of the air pump, and can also overcome changes in atmospheric pressure in different areas Changes in the attractive force of the suction head affect the accuracy of banknote counting.
