The present invention relates to a drug injection device controller capable of remote control. More specifically, it is a chemical input device controller capable of remotely controlling a chemical input for disinfection in groundwater taken from the wells of the liver abnormal water supply, or a chemical input for purifying wastewater and sewage in a wastewater treatment plant through an integrated management system.

In general, the interstitial water supply facilities using groundwater and valley water are used in areas where the installation of water supply facilities is difficult. Or, install a well in a certain area, take ground water, store it in a storage tank, and supply water to each household. At this time, raw water taken from the wells and valleys is often impossible to use as drinking water due to external factors such as environmental pollution.

In addition, facilities such as sewage treatment plants are subject to purification by adding chemicals to treat wastewater.

However, the chemicals introduced in the above process are mostly in the form of solids or powders, which are directly injected into the storage tanks for storing the raw water. In this case, a predetermined amount is determined according to the time setting regardless of the amount of raw water such as groundwater taken into the well. In most cases, the medicine is injected, and the wastewater collected from the sewerage is also collected by a manager when a certain amount is collected. Accordingly, the development of a device capable of selectively injecting drugs in accordance with the amount of raw water was required.

According to the request, the Republic of Korea Patent Publication No. 2003-0033415 (name of the invention: automatic injection system for purified water) can accurately input the purified water in a predetermined amount of water in a proper amount and the appropriate time, and the remaining amount of the drug and the time input easily In order to provide an automatic injection system for water purification medicine that notifies the remote monitor of the exhaustion of chemicals and equipment, the solar energy is converted into electric energy and used as a power supply, and the power can be charged and used.

The motor to allow the proper time and the appropriate amount of chemicals to be introduced into the A timer for providing a liver and controlling a time interval of the injected medicine, and an I / O port for communicating internal data of the storage device and external control data with an external computer through the control unit. .

According to the present invention, in inputting a solid drug into a raw water storage tank for storing raw water, the solid drug is input at a predetermined time depending on the amount of raw water introduced by detecting an amount of water introduced. However, in the present invention, since the medicine is input at a certain time by a sensor that detects the amount of raw water flowing in, when the amount of liver water used in each household increases, the solid drug is not mixed with the raw water and thus the concentration of the drug is irregular. In case of frequent occurrence, there was an inconvenience that the use should set the dosage (number) of solid medicine.

In addition, the Republic of Korea Utility Model Registration No. 319574 (Automatic disinfectant drug input system) is a main controller for wirelessly transmitting the pill inventory data and system operation status data to the main control circuit; A receiver for receiving data transmitted from such a master controller to a receiver control circuit; The operation of the motor is controlled by the control signal of the main control circuit, and the operation shaft coupled with the gear is linearly reciprocated in the sliding groove so that the driving force is transmitted from the motor.

The amount of raw water is stored in the tank where raw water is stored, and a certain amount of solid medicine is input. However, the registration proposal requires the user to input the amount of chemical and the concentration of the chemical input to the raw water was irregular. .

Therefore, in order to solve the problems described above, the user automatically inputs the liquid medicine by the arithmetic formula built in without any additional calculation of the medicine input amount, and the actual amount of the medicine is measured using a sensor or the like. By displaying the measured amount of the drug, it is possible to control the amount of the injected medicine, and to provide a drug input device controller capable of remote control to evenly spread the concentration of the drug in the raw water.
