③、Different precision specifications of the water gauge cannot be mixed and used.

Remote Telemetry Unit RTU

【Installation Location】: Installed inside the electrical control box
【Power Supply Method】:
①、Supports wide voltage supply of 10-30VDC.
②、Supports dual power supply of 10-30VDCAC and solar panel (communication should be made before leaving the factory, modification priority is AC power supply, when the AC power is cut off, the solar panel and battery provide power supply, and the equipment works normally without interruption)
【Data Upload Interval】: Settable between 30s and 1000s
【Upstream Communication Interface】:
①、Real-time upload of water level measurement and water level status through 4G/RJ45.
②、2-channel relay output, relay capacity: 250VAC/30VDC 3A. By default, both relays are associated with the water level threshold, one of which can be set to have a source or not, used for alarm or automatic control, and supports remote manual control by the server.
【Downstream Communication Interface】:
①、RS485 master station data collection interface, reads the water level data measured by the RS485 electronic water level host, baud rate 4800, longest communication distance ≥ 1500 meters
②、RS485 master station alarm control interface, when the measured water level exceeds the set water level threshold, write the alarm information to the RS485 type sound and light voice alarm module. The RS485 master station alarm control interface can be connected to two groups of RS485 sound and light voice alarm modules at the same time by distinguishing the slave address of the voice alarm module, baud rate 9600.
③、RS485 master station LED control interface, connects to the LED screen control card, and displays the water level measurement data on the LED display screen in real time. The RS485 master station LED control interface can be connected to two dual-color LED screens at the same time by distinguishing the slave address of the font library card, baud rate 9600.
④、Two switch quantity input interfaces (reserved)
⑤、Two analog quantity input interfaces (reserved)
⑥、One water浸 detection (reserved)
【Configuration Method】: The mobile APP configures the device wirelessly and non-contactably via Bluetooth, with parameters including: target address for upload, target port for upload, water level deviation value, water level threshold, water level hysteresis, delay time, data upload interval, ICCID value.

LED dual-color display

①、Size 102cm*22cm dual-color screen, red and green dual-color screen
②、The dot matrix of the unit board is 16*96, and the display mode is vertical display.
③、The normal state of communication between the remote telemetry terminal host RTU and the LED character library card:
The display content is "Current water depth 0.35 meters", which can be scroll displayed, the Chinese part is displayed in green, the digital part is normally displayed in green, and the over限 display is red.
④、The abnormal state of communication between the remote telemetry terminal host RTU and the LED character library card:
The digital part of the LED screen will display a red horizontal bar "———".
⑤、The abnormal state of communication between the remote telemetry terminal host RTU and the electronic water gauge host:
The digital part of the LED screen will display a red "0.00".
⑥、This package comes with a default LED dual-color display, if you need a bridge hole bidirectional alarm display, you can add another LED dual-color display according to actual needs.

Sound, Light, and Voice Alarm Module
①, The sound, light, and voice alarm module has an RS485 communication interface. When the measured water level exceeds the set water level threshold, the alarm control interface of the RS485 master station of the remote telemetry terminal host RTU writes the alarm information to the RS485 type sound, light, and voice alarm module.
②, When the water level does not exceed the set limit value, the sound, light, and voice alarm module does not work.
③, When the water level exceeds the limit, the voice content of the sound, light, and voice alarm module is fixed at "The current water level is deep, please pay attention to traffic safety". At the same time, the sound and light alarm works, and the sound and light alarm and voice broadcast occur once for each exceedance. After three times, it is determined whether it exceeds the limit. The interval between each broadcast is fixed at 5S.
