Embodiment 1

[0036] Such as figure 1 As shown, an automatic control system of a dosing device in the present invention includes a dosing hopper for storing medicine powder, a mixing chamber for mixing clean water and medicine powder, a medicine liquid storage tank, and also includes a PLC controller, a touch screen HMI, and a powder supply frequency converter , powder supply motor, multiple agitators, water inlet solenoid valve, flow meter, telescopic rod, material level switch, heating device, medicine temperature sensor, vibrator and liquid level gauge, the input terminals of the PLC controller are respectively connected with the touch screen The input ends of HMI, powder supply frequency converter, multiple agitators, water inlet solenoid valves, telescopic rods, heating devices and vibrators are connected, and the input ends of the PLC controller are respectively connected with the liquid level meter, flow meter, material level The switch is connected to the output end of the medicine ...

Embodiment 2

[0054] Based on embodiment 1, a kind of control method of automatic control system of dosing device comprises the following steps:

[0055] S1. Start the dosing device, set the concentration of the medicinal solution to be configured through the touch screen HMI, the PLC controller starts the agitator, and at the same time the material level switch detects the amount of medicinal powder in the dosing hopper, and the liquid level gauge detects the liquid level in the medicinal liquid storage tank high.

[0056]S2. The PLC controller starts or waits for processing according to the detection results of the material level switch and the liquid level gauge, including: if the material level switch is normal and the liquid level of the medicinal solution is lower than the preset threshold value, enter step S3; if the material level switch If it is abnormal or the liquid level of the medicinal solution is higher than the preset threshold value, go to step S4.

[0057] S3. The PLC con...

Abstract

The invention provides an automatic control system of a dosing device. The automatic control system comprises a PLC, a touch screen HMI, a powder supply frequency converter, a powder supply motor, a plurality of stirrers, a water inlet electromagnetic valve, a flow meter, a telescopic rod, a material level switch, a heating device, a liquid level meter, a medicine temperature sensor and a vibrator. The invention further discloses a control method of the automatic control system of the dosing device. According to the automatic control system and the control method thereof, the dosing device isstarted, the concentration of a to-be-prepared medicament liquid is set through the touch screen HMI, the PLC performs operation judgment, the PLC opens the water inlet electromagnetic valve and turnson the powder supply motor, full-automatic medicine dispensing can be achieved through HMI one-key operation on a man-machine operation interface, the medicine proportioning concentration is precise,automatic control over the dosing device is achieved, the operation is easy, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to an automatic control system of a dosing device and a control method thereof. Background technique [0002] Due to the continuous improvement and maturity of the dosing device technology, it has been widely used in various industries. Users have higher and higher requirements for the automatic control system of the dosing device. In the past, the control lines connected by hard wires had complex circuits, The shortcomings such as low reliability can no longer meet the current actual use requirements. In order to improve the use efficiency of the dosing device, there are also high requirements for the automatic control system of the dosing device. The automatic control of the dosing device is realized by using the programmable logic controller PLC and the human-machine interface HMI. Contents of the invention [0003] The object of the present invention is to provide an ...
