The farmland irrigation water resource controller is a new product developed by our company for farmland irrigation water management. It has advanced technology, stable and reliable system, and can meet customer needs. It can realize that all users in a village can use the irrigation water meter control terminal in the village, realizing the function of multiple meters and cards. And the village is not connected, that is, users in this village cannot swipe their cards to use the water meter control terminals in other villages' wells. Successfully eliminated the disputes caused by this.

At the same time, this control terminal has the function of preventing user disputes in this village. During the user's use phase, if there is an abnormal power outage or termination of use without swiping the card, the pump will be turned off. After the next power on, if other users are unable to use it, the system will prompt them with the user ID of the previous user and inform them that the current system does not allow new users to use it. The previous user must swipe their card before other users can use it normally. This avoids disputes caused by the loss of remaining balance in the user card due to abnormal termination or human damage by the user.

The usage process adopts a three-step system. The user only queries the balance information when swiping the card for the first time, switches on the pump and uses water when swiping the card for the second time, and switches off the pump and replenishes the unused water when swiping the card for the third time. All data in the user's card will be deducted using a prepaid method, and other users are not allowed to swipe the card while the current user is using it.

basic function

The system adopts a low-power microcontroller design, which has the characteristics of fast speed and good performance.

The controller adopts a Chinese dot matrix LCD display, with a friendly interface, clear and intuitive.

The system is powered by AC380V or AC220, ensuring reliable and safe operation.

The controller has two alarm modes, sound and light, with different fault alarm methods.

The system adopts high-frequency RF chips and two sets of key systems, which are secure and reliable.

Support M1 RF card communication, with a distance of up to 6cm or more.

Implement the function of multiple tables and cards, allowing multiple users to use multiple tables in the same area.

It has anti magnetic attack function and can automatically shut down the pump when magnetic interference occurs.

It has the function of abnormal pump shutdown, and the system automatically shuts down when there is no pulse for a long time, abnormal power failure, and zero remaining capacity.

Customizable anti pulse line damage function (customized for different users with different base tables).

To avoid disputes involving multiple users using the service simultaneously, only one user can use it, and other users can only access it.

Equipped with power failure protection, the system power supply is powered off, and there is a backup battery to maintain the system's data storage and keep the clock running.

The working voltage of the core part of the system is DC3.3V, and the voltage of the sampling and control part is DC12V, which is stable and reliable.

The system supports optional infrared meter reading function, which can read 800 user usage records.

The system has a power-off recording function, which records the date and time of power failure and allows for the retrieval of power-off information.

The user card is lost and can be replaced.
