[0027] In order to solve the above-mentioned problems, in this technical solution, a liquid level meter 7, an intelligent Internet of Things switch 3, a dosing pump 1 and a controller 2 are added to the existing dosing tank 6. Under the instruction of the operator, the controller 2 can realize remote control of dosing, that is, the medicine is extracted from the dosing tank 6 through the medicine suction pipe 8, and then the medicine is pumped into the pipeline of the industrial circulating water cooling system through the medicine outlet pipe 9, so as to ensure the continuous supply of the medicine, and the operator does not need to go to the site for operation. At the same time, the operation rate of the dosing pump 1 can be remotely adjusted according to the water quality monitoring data of the industrial circulating water cooling system, thereby greatly reducing the labor intensity and thus reducing the labor cost. In addition, when the liquid level meter 7 detects that the amount of medicine in the dosing tank 6 is lower than the preset threshold, the controller 2 automatically issues a command to stop the dosing pump 1 to avoid emptying, and sends an early warning to the controller 2 through the intelligent Internet of Things switch 3 to remind the operator to replenish the medicine to the dosing tank 6 in time. After the medicine is replenished, the dosing pump 1 is automatically started to continue dosing.

[0028] Furthermore, the automatic dosing device for the industrial circulating water cooling system also includes a mobile terminal 5, and the mobile terminal 5 is connected to the intelligent Internet of Things gateway 3 by wireless communication.

The barcode label is preferably a QR code, which contains information about the smart IoT gateway 3 and other devices in the system, and can be set on the smart IoT gateway 3 in the form of pasting or the like.

[0041] In addition, in order to drive the dosing pump 1, the intelligent IoT gateway 3 is also connected to an analog output module, and the dosing pump 1 is electrically connected to the analog output module, thereby realizing the control of the dosing pump 1.
