The designs of acousto-optics reports to the police divides have two parts,one part ad an independent module crustification is used in the electric circuit, completes reportment to the police when the liquid surpasses security highly in the vessel.Another part connects with the control module, according to request when in the vessel the liquid achieved the weight of supposed, the system needs to send out the buzzing sound, this part needs the MCU control after the signal judgment which is sended by the sensor .

声光报警分两部分设计，其中一部分作为一个独立的模块镶嵌在电路中，完成容器内液体超过警戒高度时的报警；另一部分与控制模块连接在一起，根据要求当容器内液体达到欲设重量时，系统需要发出蜂鸣声，这一部分需要单片机根据传感器送来的信号判断后进行控制。

And due to the nature of the data acquisition, three data acquisition circuit board are adopted. They are voltage to digit data converting circuit board, current to digit data converting circuit board and digit data input/output circuit board. These circuit boards are used to acquire the main running parameter of the multifunctional experimentation equipment and to control the output of alarm message.The monitor and control program is developed on Delphi5.0 which is an excellent product of Borland Corp.
