The vacuum degree in the food container packaged by the vacuum packaging technology of the packaging machine is generally 600-1333 Pa. Vacuum packaging is also referred to as a reduced pressure package or an exhaust package. The pressure swing control design of the vacuum packaging machine is required, The embedded control technology is adopted to optimize the design of the vacuum packaging machine for the sealed transformer, and the intelligent monitoring level of the vacuum packaging machine is improved [1] . The design of the vacuum packaging machine related to the design method of the sealed transformer is of great significance for power transmission and distribution and the optimization of the power grid. The design method of vacuum packing secret seal transformer has always been the focus of people [2, 3] .

According to the overall structure analysis of the sealing transformer of the vacuum packaging machine of Fig. 1 , and the cache control of the pressure swing control of the vacuum packaging machine is carried out in the cache component, and the process control capability of the pressure swing control of the vacuum packaging machine is improved. On the basis of the overall design of the sealing transformer of the vacuum packaging machine, the component design and the hardware development environment analysis of the sealing transformer of the vacuum packaging machine are carried out, the dynamic range of the multi-channel data record of the vacuum packaging machine control information acquisition is set to −10 dB to +10 dB, the configuration of the Linux kernel is a large amount of 120KB, the ISA/EISA/Micro Channel expansion bus is adopted to carry out the command loading of the pressure swing control of the vacuum packaging machine, the integrated control method is adopted to carry out the hardware modular design of the pressure swing control of the vacuum packaging machine, the program loading of the pressure swing control of the vacuum packaging machine is carried out by adopting a single-chip microcomputer logic command control method, the output bus control of the sealing transformer of the vacuum packaging machine is controlled by adopting a voltage impulse response control method, and the manmachine interaction interface module is constructed [5] , and the data storage center is provided with a vacuum packaging machine, a pressure swing control and a manmachine interaction design, an output bus control module is established, and the manmachine interaction and the cross-compiling of the sealing transformer of the vacuum packaging machine are carried out (Fig. 2) . Negative feedback control system is mainly controlled by switching power supply, and the design of main control links is very important. This paper mainly controls the charging system of the power battery of the sealing transformer of the vacuum packaging machine. The specific control methods are the inner loop control, the voltage outer loop control and the double loop control. When the power device is on or off, the main circuit is affected by different circuit topologies and exists as a nonlinear system. In the process of engineering design, it is necessary to get the equivalent circuit model of low frequency according to the average method of state space, and then design the regulator according to the existing performance index. In order to get better dynamic and static effects of the transformer, the negative feedback combination of voltage or current is often used in the design. The main control circuit consists of four parts: (1) Current control return. (2) Charging current and capacity display circuit. (3) Test sampling circuit. (4) Alarm circuit. Because of various factors in the circuit, switching power supply is very easy to fail. Therefore, when selecting the type and type of switch, it is necessary to carefully consider and select according to the actual situation of the circuit. When choosing transformer, we must use high frequency transformer. The performance of this transformer is relatively good, but it has higher requirements for the use of magnetic materials. The transformer can give stable voltage output to the circuit, so that the circuit can reduce the voltage impact when it works. Due to the different frequency of the power supply, the loss of the common capacitor is quite large for the power supply with high frequency, and the inductance also increases. With the increasing frequency, the attenuation phenomenon is very obvious, which can not meet the normal use requirements. Therefore, when selecting capacitors, it is necessary to decide whether to select special capacitors according to the actual situation of the circuit, so as to meet the requirements of high frequency and high temperature resistance, so that the circuit can run stably. When the system is powered on, the SCM will test the power supply and charger. When the power supply and charger are working normally, the single chip microcomputer will feed back the detection sampling to the internal system, and finally decide which charging form to use, which has reached the charging requirements. PWM pulse width can effectively control the whole process of charging, so that trickle, large current, overcharge and floating charge are all under control. When multiple tests are carried out, it is found that the battery voltage is higher than the specified voltage set in the single chip microcomputer, or the temperature is higher than the preset temperature, so the floating charge state is turned on and an alarm is given at the same time. By the analysis of the overall design framework and function modularization of the sealing transformer of the vacuum packaging machine, the components of the sealing transformer of the vacuum packaging machine are developed and designed.
