product details

[Power supply method]: External power supply 10-30VDC power supply

[Support dual power supply reform]: Support dual power supply of 10-30VDC mains and solar panels (good communication is required, the mains power supply is given priority before leaving the factory, when the mains power is cut off, the solar panels and batteries provide power, and the normal operation of the equipment will not be interrupted)

[Data upload interface]:

①. Upload the water level measurement value and remaining power of the underground water monitoring point in real time through any 4G/RJ45 method.

②. One RS485 slave interface can be connected to an audible and visual alarm and a speaker. Two sets of audible and visual alarms and speakers can be connected at the same time. They are distinguished by address and the baud rate is 9600.

③. One 485 slave interface can be connected to a font card. This can be connected to two two-color LED screen font cards at the same time. They are distinguished by address. The baud rate is 9600. The font card uses a two-color screen font card and the display mode is vertical display.

④. 2 relay outputs, relay capacity: 250VAC/30VDC 3A. By default, both relays are associated with water level limits, and both can be configured to be active or passive, used for alarm or automatic control, and support remote manual control by the server.

[Data collection communication interface]:

① Adopt LORA wireless communication, a low-power LAN wireless standard developed by semtech company. This communication method achieves the unification of low power consumption and long distance. Paired with our company's unique LORA wireless communication protocol, it can simultaneously conduct wireless long-distance communication with 32 underground water monitoring points within the effective communication distance. In terms of communication, it avoids mutual interference between terminal nodes during the signal transmission process. interference, and avoids the problems of short communication transmission distance and insufficient penetration of traditional wireless devices.

②. Two switching interfaces (reserved)

③. Two analog interfaces (reserved)

④. Water immersion detection all the way (reserved)

[Configuration method]: The mobile APP configures the device through Bluetooth wireless link. The parameters include: upload target address, upload target port, upper limit of water level of each channel, parameters of each channel, channel display content, and the status of each measuring point equipment can be viewed in real time. , water level value and battery power, data upload interval, ICCID value.

Audible alarm:

①, RS485 voice broadcast, light alarm

② When the water level does not exceed the set limit, the audible and visual alarms and horns will not work.

③ When the limit is exceeded, the loudspeaker will broadcast, and the alarm content will be consistent with the display content. At the same time, the sound and light alarm works. Once the limit is exceeded, the sound and light alarm and loudspeaker will broadcast three times. After three times, it will be judged whether the limit is exceeded. The interval between each broadcast is fixed at 5 seconds.

④. When the measuring point is offline, the alarm content will be consistent with the display content, and the audible and visual alarm will work at the same time.

[Equipment composition]: The underground water measuring point is composed of a waterproof and anti-corrosion 304 stainless steel shell, a water level detection module (water depth, water status), Bluetooth configuration module, LORA wireless communication module, built-in lithium battery, etc.

[Working Principle]: Based on the liquid-mediated ultrasonic sensor, the time interval from emission to reception of the sound wave is measured, and the distance of sound wave transmission is obtained by combining the compensated sound speed of the sound wave. The current liquid level can be obtained based on the time difference from when the installed measuring point transmits the ultrasonic wave to when it receives the echo from the water surface.

[Power supply method]: Built-in battery power supply (3.6V lithium sub-battery 38000mAH)

[Battery life]: It can work continuously for more than 5 years without water accumulation (upload one message in 5 minutes without water accumulation, upload one message in 1 minute with water accumulation)

[Water level range]: ≤1.5m

[Water level error]: 1cm

[Resolution]: 1mm

[Output signal]: LORA wireless spread spectrum signal

[Shell material]: 304 stainless steel

[Protection level]: IP68

[Installation method]: The underground installation method is adopted, and an installation hole is opened at the road installation equipment. The equipment dimensions are as shown in the figure below. After the hole is opened, place the device vertically into the installation hole, pour filler into it, and secure the device. Note: Make sure the top remains level so as not to affect the measurement.

[Equipment size]: Height 187mm, cavity diameter 60mm, top disk diameter 120mm.

[Communication interface]: Using LORA wireless communication, a low-power LAN wireless standard developed by semtech company, this communication method achieves the unification of low power consumption and long distance. Paired with our company's unique LORA wireless communication protocol, it can communicate with our company's Sekisui Monitoring Station host computer wirelessly over long distances, with a communication line-of-sight up to 800m.

[Configuration method]: The mobile phone APP configures the device through Bluetooth wireless link.

[Comprehensive introduction]: In order to solve the many inconveniences of customers' self-built servers without fixed IP (or domain name), daily maintenance, attack prevention, uninterruptible power supply, etc., our company has specially developed and launched a free environmental monitoring cloud platform service.

The comprehensive environment cloud platform is based on advanced information collection systems, the Internet of Things, cloud platforms, big data and the Internet and other information technologies.
