Remote signaling: It is required to adopt the passive contact mode, that is, the input of a certain remote signal should be the contact of a pair of relays, or closed, or disconnected. The YX module converts the closing or disconnection of the relay contacts into a low-level or high-level signal into RTU through the remote signaling terminal board.
The remote signaling function is usually used to measure the following signals: the position signal of the switch, the comprehensive signal of the internal fault of the transformer, the action signal of the protection device, the operation signal of the communication equipment, and the position signal of the tap of the voltage regulating transformer. The operating state signal of the automatic adjusting device and other signals that can be output in the form of relays; The total signal of the accident and the power failure signal of the main power supply of the device, etc.
Telemetry: Telemetry is often divided into important telemetry, secondary telemetry, general telemetry, and total telemetry. The telemetry function is commonly used for active and reactive power acquisition of transformers; active power harvesting of the line; bus voltage and line current acquisition; Temperature, pressure, flow rate (flow rate), etc.; Frequency acquisition and other analog signal acquisition.
Remote control: Passive contact mode is adopted, and its correct action rate is required to be not less than 99 99 %.
The so-called correct action rate of remote control refers to the probability of its non-misoperation, and the general rejection is not considered to be incorrect, and the remote control function is often used in the combination and distribution of circuit breakers and capacitors and other occasions that can be controlled by relays.
Remote adjustment: Passive contact mode is adopted, and its accuracy is required to be greater than 99 99 %.Remote regulation is often used for the lifting and lowering adjustment of the tap of the on-load voltage regulating transformer and other occasions where a set of relays can be used to control the function of graded lifting.
Remote signaling is the remote status signal, which is to transmit the equipment status signal of the monitoring plant to the dispatcher from a long distance, such as switch position signal, protection signal, etc. (Status Signal).
Telemetry is remote measurement, which is to transmit the main parameter variables of the monitored plant to the dispatcher over a long distance, such as the power, voltage, and current at the plant end. (Measurements).
Remote control is remote control operation, which is to issue commands from the dispatching or monitoring center to achieve remote operation and switching.

Telemetry, remote signaling, remote control, and remote regulation of the power system refer to:
1. Telemetry: remote measurement. It refers to the collection and transmission of operating parameters, including various electrical quantities (voltage, current, power and other values on the line) and load power flow.
2. Remote signaling: remote signal. It refers to the collection and transmission of various protection and switching information.
3. Remote control: remote control. It refers to accepting and executing remote control commands, mainly opening and closing, and remote control of some remote switch control equipment.
4. Remote adjustment: remote adjustment. It refers to receiving and executing remote adjustment commands to remotely debug remote control equipment, such as adjusting the output power of generators.

Hello, according to your question, I think the term is explained to generally refer to infrared sensing for remote control.

Far away as a sense of age; Wide-open observation of geodynamic and clever slag.

Selective radiator: A radiator whose emissivity varies with wavelength is closed, that is, a selective radiator, such as xenon lamp and mercury lamp.
Brightness and humidity (I haven't heard the sedan parade say, b sweat, only know the brightness temperature).
Grayscale spectroscopy: The grayscale curve is used to describe the characteristics of reflecting, emitting, and absorbing electromagnetic waves with wavelength.
Independent variable: A quantity whose value does not change with other quantities.
Texture features: The characteristics of the surface details of the ground object on the remote sensing image.
Chroma space: A mathematical representation of the color of hue into a three-dimensional space model.
Thermal infrared remote sensing: It is a remote sensing method that collects and records the thermal infrared radiation information that cannot be seen by the human eye through the thermal infrared detector, and uses this thermal infrared information to identify ground objects and invert surface parameters.
Reflection Factor: The ratio of the reflected radiant energy of the target to the incident radiant energy.
Control point: A fixed point that measures the plane coordinates, elevation, and/or gravitational acceleration of the point with a certain accuracy.
Bidirectional reflectance distribution function: It is a function that describes the basic parameters of the spatial distribution of reflection characteristics when both the incident and reflection angles are small solid angles.
Reason: Piezoelectric sensors are acceleration sensors, and there is no acceleration in static, so they cannot measure static signals, nor can they measure uniform motion. >>>More
