Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the flow chart of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes control module, steering engine module, sensor module, display module, voice mould
Block and input module, control module connect with steering engine module, sensor module, display module, voice module and input module respectively
It connects, sensor module includes weighing sensor and ultrasonic sensor.The title medicine container of the utility model uses symmetrical above and below point
The hourglass shape taper container of cloth, the vertex intersection of two circular cones, centre are separated by a plastic plate, are equipped in the container of upper end super
Sonic sensor, lower end are equipped with weighing sensor.
Control module processing speed is fast, controls steering engine module rapidly after weighing and container both ends are isolated, and stops medicine
The crawl of object.Steering engine module can control the plastic plate among container and stretch, and for separating container, stop weighing for container.Claim
It retransmits sensor and selects electromagnetic type weighing sensor, worked using the load on bearing platform with the principle that electromagnetic force balances each other, electricity
Magnetic-type sensor precision is high, and error is small, can more accurately weigh, accuracy up to 1/2000~1/60000,
But range of weighing only between tens milligrams to 10 kilograms, is placed in the container of lower end, is weighed to powdery type Chinese medicine；It is super
Sonic sensor is placed on the upper end of container, for detecting the consumption degree of powder similar drug, if chemical consumption excessively can be with
Voice reminder is issued by voice module, drug is replenished in time.The weight of alleged drug can be arranged in input module, according to set
The weight set carries out the crawl of equivalent powder similar drug.Display module can show that drug in the weight and container of current drug
Height.
Steering engine module can control the plastic plate among container and stretch, and steering engine module is a kind of driver of position servo,
It is applicable to the control system that angle constantly changes and can keep.It controls signal and microcomputer mould is entered by the channel of receiver
Block obtains resulting DC offset voltage.There is a reference circuit in inside, and the generation period is 20ms, and width is the benchmark of 1.5ms
The DC offset voltage of acquisition is compared by signal with the voltage of potentiometer, obtains voltage difference output.Voltage difference it is positive and negative defeated
The positive and negative rotation that motor drive ic determines motor is arrived out.When one timing of motor speed, potentiometer is driven by cascade reduction gearing
Rotation, so that voltage difference is 0, motor stalls.
Weighing sensor uses piezoelectric pressure indicator, is mainly made of quartz wafer, diaphragm, thin-wall tube, shell.Stone
English chip is overlayed in thin-wall tube by multi-disc, and the thin-wall tube by tensing adds preload force to quartz crystal.Experience external pressure
