液体调料添加系统工作过程：当液体调料添加系统需要工作时，PLC分别控制泵23工作和电磁阀24打开管路，使液体调料从相应的储料罐20抽出，并通过电磁阀24工作打开相应回路，使所需的液体调料得到传送炒锅，从而完成调料添加。The working process of the liquid seasoning adding system: when the liquid seasoning adding system needs to work, the PLC respectively controls the pump 23 to work and the electromagnetic valve 24 to open the pipeline, so that the liquid seasoning is drawn out from the corresponding storage tank 20, and the corresponding solenoid valve 24 works to open the corresponding Loop, so that the required liquid seasoning is sent to the wok, so as to complete the addition of seasoning.
固体调料自动添加系统的工作原理是，当固体调料类型选定时，调料的密度、其与料盒的孔径比、摩擦系数是固定不变，通过PLC控制料盒振动的振幅、频率和振动时间实现固体调料精确添加。液体调料自动添加系统包括储料罐、泵、输料管四大部分；当油泵型号和液体调料类型选定时，油泵排量、工作效率为定值，通过PLC控制油泵转速和工作时间，就能实现对液体调料精准添加量。控制系统：PLC控制器、PLC输入端的启动停止等开关、固体调料选择开关、液体调料选择开关，PLC输出端包括各类中间继电器，实现对固体调料的仓壁振动器以及步进电机工作、同时实现对液体调料各类电磁阀以及油泵电机工作。The working principle of the solid seasoning automatic adding system is that when the type of solid seasoning is selected, the density of the seasoning, its aperture ratio to the material box, and the friction coefficient are fixed, and the amplitude, frequency and vibration time of the material box vibration are controlled by PLC Realize the precise addition of solid seasoning. The liquid seasoning automatic adding system includes four parts: storage tank, pump, and feeding pipe; when the oil pump model and liquid seasoning type are selected, the displacement and working efficiency of the oil pump are fixed values, and the speed and working time of the oil pump are controlled by PLC. Accurate addition of liquid seasoning can be realized. Control system: PLC controller, start and stop switches of PLC input terminal, solid seasoning selection switch, liquid seasoning selection switch, PLC output terminal includes various intermediate relays, to realize the operation of the bin wall vibrator and stepping motor for solid seasoning, and at the same time Realize the work of various solenoid valves and oil pump motors for liquid seasoning.
智能炒菜机调料自动添加系统控制方法，如图7所示，具体按照以下步骤实施：The control method of the intelligent cooking machine seasoning automatic adding system, as shown in Figure 7, is implemented according to the following steps:
步骤1，启动时，控制系统开机自检，进行初始化；Step 1, when starting up, the control system starts self-test and initializes;
步骤2，判断是否有炒菜任务；如果有没炒菜任务，继续等待；如果判断有炒菜任务，则进一步判断是否需要添加调料；当需要添加调料时，进行步骤3；Step 2, judge whether there is a cooking task; if there is no cooking task, continue to wait; if it is judged that there is a cooking task, then further judge whether it is necessary to add seasoning; when it is necessary to add seasoning, go to step 3;
步骤3，判断添加调料类型，为固体的，进行步骤4，为液体的，进行步骤5；Step 3, determine the type of seasoning to be added, if it is solid, go to step 4, if it is liquid, go to step 5;
步骤4，当添加的调料为固体调料时，由控制系统中的固体调料控制模块计算需要添加固体调料种类、添加的时间，并通过PLC输出端控制相应的仓壁振动器以及相应步进电机工作打开挡片相应的大小，实现固体调料添加，Step 4, when the added seasoning is solid seasoning, the solid seasoning control module in the control system calculates the type of solid seasoning to be added and the time to add it, and controls the corresponding bin wall vibrator and corresponding stepping motor through the PLC output terminal Open the corresponding size of the baffle to realize the addition of solid seasoning,
添加后，进一步判断固体调料添加时间是否结束，尚未结束时控制系统等待，如果添加调料结束时间到，PLC控制相应继电器断电，相应仓壁振动器及步进电机停止工作、挡片复位，PLC程序返回初始；After the addition, it is further judged whether the time for adding the solid seasoning is over. When the time is not over, the control system waits. If the time for adding the seasoning is over, the PLC controls the corresponding relay to power off, the corresponding bin wall vibrator and stepping motor stop working, the block is reset, and the PLC The program returns to the initial;
步骤5，当需要添加的调料为液体调料时，由控制系统中的液体调料控制模块计算添加的液体调料种类和添加时间，并通过PLC输出端控制相应电磁阀及相应液体泵工作，实现液体调料添加，Step 5, when the seasoning to be added is a liquid seasoning, the liquid seasoning control module in the control system calculates the type of liquid seasoning to be added and the adding time, and controls the corresponding solenoid valve and the corresponding liquid pump through the PLC output to realize the liquid seasoning Add to,
并且同时判断液体调料添加时间是否结束，尚未结束时PLC控制系统等待，若液体调料添加时间结束，PLC通过相应继电器断电，相应液体调料回路电磁阀及液体泵停止工作，PLC程序返回初始。And at the same time, it is judged whether the time for adding liquid seasoning is over. When the time for adding liquid seasoning is not over, the PLC control system waits. If the time for adding liquid seasoning is over, the PLC will cut off the power through the corresponding relay, and the solenoid valve and liquid pump of the corresponding liquid seasoning circuit will stop working, and the PLC program will return to the initial stage.
采用本发明的方法，通过PLC控制，能够实现固体和液体调料自动精确添加。固体调料和液体调料添时间可有下面公式计算：By adopting the method of the invention, the automatic and precise addition of solid and liquid seasonings can be realized through PLC control. The adding time of solid seasoning and liquid seasoning can be calculated by the following formula:
其中，固体调料添加量Qg的计算方法为：Wherein, the calculation method of solid seasoning addition Qg is:
Qg＝νg×tQg = νg ×t
νg表示下料速度，单位是克/秒，A为料盒振动幅度，f为料盒振动频率，c为常数，θ为调料密度，λ为孔径比，ζ为料盒与调料之间的摩擦系数，。νg represents the feeding speed, the unit is g/s, A is the vibration amplitude of the material box, f is the vibration frequency of the material box, c is a constant, θ is the seasoning density, λ is the aperture ratio, ζ is the distance between the material box and the seasoning Coefficient of friction,.
由于对于某种固体调料，调料的密度、其与料盒的孔径比、摩擦系数是固定不变的；如果固定仓壁振动器振动频率和振幅，只需要PLC控制器控振动时间，就能精准控制固体调料的添加量。Because for a certain solid seasoning, the density of the seasoning, its aperture ratio to the material box, and the friction coefficient are fixed; if the vibration frequency and amplitude of the bin wall vibrator are fixed, only the PLC controller needs to control the vibration time to accurately Control the amount of solid seasoning added.
液体调料添加量：Amount of liquid seasoning added:
Qy＝Vy×n×η×tQy ＝Vy ×n×η×t
Qy表示液体调料添加量，Vy表示排量，n表示转速，η表示油泵工作效率，t表示油泵工作时间。Qy represents the amount of liquid seasoning added, Vy represents the displacement, n represents the rotating speed, η represents the working efficiency of the oil pump, and t represents the working time of the oil pump.
当液体泵选定确定时，排量Vy为定值，同时当输送液体调料类型选定时，油泵工作效率η也为定值，液体泵额定转速也为定值，只用通过PLC控制液体泵工作时间t，就能控制液体调料添加量。When the liquid pump is selected and determined, the displacement Vy is a fixed value. At the same time, when the type of liquid seasoning is selected, the working efficiency η of the oil pump is also a fixed value, and the rated speed of the liquid pump is also a fixed value. Only the liquid is controlled by PLC. The pump working time t can control the amount of liquid seasoning added.
研究表明，固体颗粒可通过振动方式在重力作用下实现下料；本发明通过分析菜品调料类型可知，调料总体上可分为固体颗粒调料和液体调料；进一步研究表明菜品固体调料加添的料量与下料时间、下料速度成比例，而下料速度与振动频率、下料孔横截面积、调料密度、调料材质与下料管(或筛网)材质摩擦系数等因素有关。在下料过程中，下料孔截面积、每种调料密度、摩擦系数是固定的不变，因此，通过PLC控制固体颗粒调料下料振动频率和下料时间就能控制下料量。另外，液体能通过泵进行输送，液体输送量与泵的排量、效率以及工作时间相关。基于此原理，可设计一种智能炒菜机调料添加系统，从而实现智能炒菜机的调料自动添加。Studies have shown that solid particles can be fed under the action of gravity by vibrating; the present invention can be known by analyzing the types of dish seasonings, and the seasonings can be divided into solid particle seasoning and liquid seasoning on the whole; further research shows that the amount of food solid seasoning added It is proportional to the feeding time and feeding speed, and the feeding speed is related to factors such as vibration frequency, cross-sectional area of the feeding hole, seasoning density, seasoning material and material of the feeding pipe (or screen) and other factors. During the feeding process, the cross-sectional area of the feeding hole, the density of each seasoning, and the friction coefficient are fixed. Therefore, the amount of feeding can be controlled by controlling the vibration frequency and feeding time of solid particle seasoning by PLC. In addition, the liquid can be transported by the pump, and the liquid transport volume is related to the displacement, efficiency and working time of the pump. Based on this principle, an intelligent cooking machine seasoning adding system can be designed, so as to realize the automatic adding of seasoning in the intelligent cooking machine.
