Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 19705-2005 "hydrological instrumentation signals and interfaces," compared with GB/T 19705-2005, in addition to editorial repair
Change, the main technical content changes are as follows.
--- Modify the normative references;
--- Combined "non-smart sensor" and "smart sensor" as "sensor";
--- Increased rotor-type flow meter (see 5.2.1), tipping bucket rain gauge (see 5.2.2), float level gauge (see 5.2.3), telemetry evaporation
(See 5.2.4), interface and signal requirements of hydrographic cable test equipment (see 5.2.5);
--- Added some other sensor interface (see 5.2.6);
--- Increased sensor output signal related content (see 5.2.9,5.2.10);
--- Added "frequency interface" "network interface" "optical interface" (see 5.3.1.1);
--- Added "digital transmission equipment can have a number of relay output interface" (see 5.3.2.4);
--- In the "I/O interface connector and pin definition" (see 5.4) to add a plug-in and pin definition table.
This standard is proposed by the Ministry of Water Resources of the People's Republic of China.
This standard by the National Hydrological Standardization Technical Committee (SAC/TC199) centralized.

3.1
Signal signal
A change in one or more characteristic quantities may be used to represent the physical phenomenon of information. The meaning of the signal specifically refers to the hydrological instrument sensor and significant
Show, record or transmit data between devices and between hydrological devices and other automation system equipment.
3.2
Interface
Necessary hardware and accompanying software for communicating between two or more modules (or components, devices). Is a module (or component, device)
The common boundary between. The meaning of the interface specifically refers to the hydrological instrument sensor and display, recording or data transmission equipment and hydrological instruments and their
The hardware and accompanying software that communicates between his devices (such as a computer).
3.3
Data transmission equipment datatransmissionequipment
Data transmission equipment refers to the equipment that can automatically collect and transmit parameters (or have storage and partial control functions).
4 categories
4.1 Signal Classification
4.1.1 hydrological instrument signal according to the information flow into the input signal, the output signal. Sensor measurement output signal is displayed, recorded or
The input signal of the data transmission equipment.
4.1.2 hydrological instrument signal according to the mechanism of the source is divided into passive on-off signals and active voltage signals, current signals, frequency signals,
