Describe below in conjunction with the course of work of instantiation the supply unit of microprocessor control:
As shown in Figure 6 be an electroplating assembly line equipment therefor, this device is by electroplating bath 19, material conveyer belt 20, number hole sensor 17, charging transducer 18, discharging transducer 23 is formed, wherein the material 22 that needs can be electroplated of material conveyer belt is sent to opposite side from a side of electroplating bath, evenly be provided with and count big or small apertures 21 such as hole sensor on the material conveyer belt, the material that needs plating can be placed in the below of material conveyer belt, the number hole sensors be packed in the material conveyer belt directly over the electroplating bath casing of charging one side on, the charging transducer is packed on the electroplating bath casing of charging one side, the discharging transducer is packed on the electroplating bath casing of discharging one side, and above-mentioned three transducers are the non-contact optoelectronic transducer.
After the opening power, can carry out the setting of magnitude of voltage or current value to the designated external controlling object by the operation push-button on the power supply box front panel, and be kept in the memory, its operation is as follows:
Have in input under the situation of corresponding material external control signal, press voltage simultaneously and key is set and increases key or the minimizing key, be transferred to given voltage, press storage key then, can store the magnitude of voltage of this material; Perhaps pressing electric current is provided with key and increases key or the minimizing key, be transferred to specified current flow, press storage key then, can store the current value of this material, the magnitude of voltage or the current value of 5 external control objects can be set at most, and an external control object is corresponding with a kind of magnitude of voltage or current value of material.
After adjusting voltage (electric current) value, power control circuit is received a kind of external control signal of material, this moment, material brought into operation under the drive of material conveyer belt, number hole sensor, charging transducer and discharging transducer are started working simultaneously, meanwhile corresponding material indicator light on the supply unit front panel of microprocessor control is lighted, and the transducer indicator light begins to have the variation of light on and off.Power control circuit reads voltage (electric current) value of this external control object from memory, and the material of logarithm hole sensor, charging transducer, discharging sensor carries out analyzing and processing, and voltage (electric current) signal that needs are increased or reduce is transferred on the main power source through digital regulation resistance and exports needed voltage (electric current) value.How much in direct ratio material in this voltage (electric current) output valve and the electroplating bath is.After this external control signal disappeared, this voltage (electric current) output valve was zero.Along with material reduces gradually, this voltage (electric current) output valve reduces gradually, up to being output as zero.
Be example to receive external control signal 1 below, illustrate outside controlling object 1 is carried out the operation principle that voltage is adjusted:
If main power source parameter: direct voltage is 7.5V, and direct current is 200A.When external control signal 1, microprocessor reads the predefined magnitude of voltage V1 of this material from memory, the voltage V1 of appointment is divided into V1/N part, because the controller builtin voltage is by digital control, 100 stages of digital potentiometer W9312WP, 7.5V voltage is divided into 100 grades automatically, adjust voltage 0.075V for every grade, for example: when the hole count of material conveyer belt is 200, the V1 value is 5V, and the adjustment progression of V1 voltage correspondence is: the 100/7.5*V1=67 level, that is per 3 holes are one-level, 3 holes of just every mistake, voltage increases 0.075V.
