Description

Disinfectant automatic dosing system and its control method {DISINFECTANT AUTOMATIC DROPPING SYSTEM FOR CLEAN WATER AND CONTROLLING METHOD THEREOF}

The present invention relates to automatic disinfectant input, and to a disinfectant automatic dosing system used in a simple water purifier, a purified water tank, etc. to put the disinfectant into the water stored in the simplified water storage tank and drinkable water, and a control method thereof. It is about.

Generally, the water storage tank is divided into shapes such as a rectangle and a cylinder, and is divided into concrete, resin material, and stainless material according to panel assembly type, masonry type, unit stack type, and materials used.

These water storage tanks come in various shapes and sizes, taking into account their economic feasibility along with their storage capacity, size, use and use.

In particular, the water storage tank used as a water purifier additionally includes a disinfectant dispensing device such as a chemical injector or a chlorine injector.

In the disinfectant dispensing device according to the prior art, a vacuum self-contained chlorine injector that directly attaches to a chlorine container valve to inject chlorine gas, and a solid chlorine injector of a water tank that injects solid chlorine directly into a water tank (Registration Utility Model No. 20) -263574).

Regardless of how they are used, they aim to mix disinfectants such as chlorine into the water in the water storage tank, but they do not have real-time insight into their operating conditions from remote locations.

In addition, in the prior art, in order to perform the computer control for the control of the residual amount of chlorine does not have an independent power source, there is a disadvantage that requires an external power source when applied to the actual farming or farming site.

In addition, the majority of chlorine injector is controlled by the method of injecting solid chlorine according to the time control, there is a disadvantage that it is difficult to perform precise chlorine input control.

In addition, in the case of the solid chlorine injecting device of the water tank, during the rotation of the rotating plate, the solid chlorine seated in the transport hole of the rotating plate rotates and comes into direct contact with the extra solid chlorine filled in the loading tube, whereby solid chlorine may be damaged. As a result, debris from the solid chlorine acts as an obstacle to the rotation of the rotating plate, leading to unstable operation such as operation stoppage, and it is not known until the administrator observes the operation stoppage or failure. Therefore, there is a disadvantage of very inconvenient in use and maintenance.

In addition, the conventional disinfectant injecting device has a disadvantage in that maintenance and maintenance management, such as immediate response to failure or disinfectant operation.

In addition, the disinfectant dispensing device currently used in domestic simple water purification plant is not elaborate in its operation, most of them have only a function that is operated by simply setting the time.

In addition, due to the structure of the chemical injector, the disinfectant is weakened due to moisture and is not properly input.

As a result, most of the users who drink the constant water in drinking water are drinking water that has not been disinfected.

In addition, if the disinfectant is injected regardless of the water level, the discomfort due to the very strong smell of disinfectant when drinking, it causes a harmful effect on health.

Accordingly, an object of the present invention is to wirelessly transmit the drug inventory data and the system operation state information data between the main controller installed in the water storage tank type water purification equipment and the receiver installed in the management room of the remote control of the main controller to determine the operation status in real time.

That is, a receiver installed in the home of a remote manager whose system information on the medicine (pill), errors (no medicine, drug jam, water shortage, power shortage) and normal operation status indicating the normal operation state is installed from the main controller installed in the water purification facility. By wireless communication, the administrator can manage the operation status of the input system at home. In this case, the allowable distance between the main controller and the receiver is 500m to 1Km, which is the case of open space.

-Alarm function in case of an error: There is an alarm function in the receiver so that administrators can know when an error occurs such as no medicine, weak medicine, lack of water, lack of power, and cope with each error.

Maximum drug loading: The number of chlorine disinfectant (chlorine tablets) that can be loaded in the drug dispenser of the present invention is 80 to 100. This amount is typically about 3 months of use.

-Prevention of excessive disinfectant injection: In any of the three modes of operation, if the water level is below the standard level (this level can be set by the administrator), all operations of the main controller are stopped and the administrator can know by wirelessly notifying the receiver. have.

-Automatic operation recovery function: If the main controller is stopped because the current level is lower than the standard level, or if the main controller is stopped due to a power shortage caused by battery power consumption (also notified to the administrator), the water level will be restored. If it is high or the power is charged by the solar cell, the operation is automatically performed normally. This automatic operation recovery function uses the non-volatile memory (EEPROM) for each microprocessor, so all the settings set by the administrator (disinfectant pills, time interval value, flow interval value, wireless communication interval, reference level, reference level) Power supply, mode type, etc.) are maintained even if the power supply is completely turned off.

-Manual motor rotation function: In case of medicine jam error, after removing the jammed medicine of the medicine dispenser, if the manager presses the manual operation button, the operation axis of the medicine dispenser can be initialized by slidingly moving to the initial position.

-Alarm Stop: When an error occurs, the receiver in the manager's house generates an alarm. By pressing one button, the alarm sound can be turned off. If it is not OFF, the alarm sounds every 10 minutes. Even if it is OFF, an error message is sent every hour, so to turn off the alarm for a long time, turn off the receiver or go to the main controller to clear the error. shall. When the receiver is turned on again, it returns to its original state.

As shown in Fig. 3, the operation algorithm of the main controller is stored in the nonvolatile memory, and is started by the administrator connecting the various sensors, the medicine dispenser, and the solar cell, and then turning on the power of the main controller and the receiver. .

The main control circuit selects a setting mode and an operation mode in response to the information input using the keyboard (S100).

The main control circuit applies power to the LCD according to the selection of the setting mode (S101), checks the key value input through the keyboard (S102), and determines whether the checked key value is one of the mode key value, the setting key value, and the motor key value. (S103).
