Description

A general-purpose extremely low-power hydrological sensor wireless transparent transmission adapter

technical field

The utility model relates to the technical field of electronic adapters, in particular to a wireless transparent transmission adapter for universal ultra-low power consumption hydrological sensors.

Background technique

In the automatic monitoring and reporting system of water regime or the construction of modern hydrological stations, it is often necessary to install and integrate a variety of hydrological sensors, such as water level, flow velocity, and sediment concentration. These sensors have different types, different interfaces, and different installation locations and methods. In order to meet the purpose of flood control and hydrological testing, it is necessary to collect and control many hydrological sensors in a unified manner. The on-site conditions require the equipment to have low power consumption and real-time response.

At present, the commonly used integration methods mostly adopt the wired mode and the radio mode. Although the wired method is simple, it is not suitable for the situation where the distance is long or the cable is difficult to lay, such as the hydrological sensor installed in the hydrological cableway. In addition, the use of wired cables also brings inconvenience to the increase, decrease and movement of hydrological sensors in the later stage. In the radio station mode, the radio station generally consumes a lot of power. In order to reduce power consumption, the hydrological sensor self-reporting work mode is often used, that is, the hydrological sensor is in a low power consumption state during non-working hours, and the timing time is up. Start working and send data, and then Enter the low power consumption state again. In this way, the hydrological sensor data cannot be collected in real time, and it is also inconvenient to configure and adjust the parameters of the hydrological sensor in more detail.

In recent years, OOK technology, a wireless modulation method suitable for battery-powered conditions, has gradually been widely used. The wireless module using this technology can meet the wireless real-time wake-up requirements under extremely low power consumption conditions.

On-off keying (OOK) modulation is a simple ASK method, when transmitting "0", there is no carrier signal output. Amplitude Shift Keying (ASK) is a commonly used modulation technique that is very popular in many low frequency RF digital communication systems. When it is necessary to transmit "1", the transmitting source sends a higher carrier amplitude; when transmitting "0", the simplest way is to send out a lower carrier amplitude.

ASK and OOK communication protocols are widely used in short-range wireless data transmission, such as home appliance automation, industrial networks, wireless base stations, remote key entry (RKE) and tire pressure monitoring systems (TPMS), etc. OOK is ideal for battery-operated portable devices because it efficiently conserves power when transmitting "0" (not transmitting).
