Circuit Strategy

1. Overview

The power loop strategy module uses intelligent automatic control strategies to achieve fine control of the power supply loop. Support is based on the following trigger conditions:

• Sensors: can pass different sensors and status parameters. Commonly used are brightness, illuminance, traffic sensors, etc.
• Time triggering: Timing control down to the minute level
• Latitude and longitude trigger: Dynamically adjusts based on sunrise/sunset times

It is suitable for various scenarios that require fine control of the power supply circuit.

2.3.1 Interface Description

1. Basic Information Area
   • Strategy Name: Supports editing
   • Status: Current strategy status, supports enabling and disabling the current strategy
   • Domain: Current strategy domain
   • Update Time: Display the time the strategy configuration was last updated, supports sorting by time
2. Variable Area: Displays the related variable parameters defined in the current strategy
   • Variable Name: The name defined by the user to mark the variable
   • Variable Name: The variable identifier defined by the user in the strategy parameters, used to reference the variable value in the strategy
   • Unit: The unit of the variable value, such as %, lux, Celsius degrees, etc., mainly used for identification, not affecting strategy calculation
   • Type: Current variable type, currently supports two types
     • Constant: The variable value will not change after the strategy is defined
     • Sensor: The variable value is determined by the sensor real-time status
   • Parameters: Depending on the above variable type, the meaning is different
     • Constant: When the variable type is constant, it means the constant parameter value
     • Sensor: When the variable type is sensor, you need to select the specific sensor and sensor status parameter
   • Default Value: Current variable default value
   • Description: Detailed description of the variable, helping users understand
3. Rule Area: Lists the execution conditions and status parameters in the current strategy
   • Trigger Conditions: Users can add multiple execution conditions, including:
     • Variable area variable parameter status
     • Time Parameters: Support absolute time or astronomical time (offset adjustable) time range
     • Execution Cycle: Strategy execution cycle, default is effective for all dates, supports user-defined month, day, week execution at a certain time point
   • Instruction Parameters: Power supply circuit execution instruction, break or closing

2.3.2 Configure Variables

1. Click the "Edit" button in the strategy parameter area to enter the strategy edit state.

   

2. Add constant type variables: In the variable area, select the add button to pop up the add variable interface.

   • Variable type selects constant
   • Input variable basic information: name, variable name, unit, default value
   • Constant Value: Enter the constant value or select the associated sensor device and parameter as prompted

   

3. Add sensor type variables: In the variable area, select the add button to pop up the add variable interface.

   • Variable type selects sensor
   • Input variable basic information: name, variable name, unit, default value
   • Sensor Parameters: Follow the interface guide to select the specific sensor and sensor status parameter

   

2.3.3 Variable Examples

The following are some common variable examples in tunnel lighting scenarios:

Type	Variable	Name	Unit	Description
Sensor	Q	Vehicle Flow	veh/(h.ln)	Vehicle flow sensor
Sensor	L20	Outside Brightness	cd/m2	Outside brightness sensor
Sensor	DI	Switch Status	N/A	Switch sensor (switch)
Constant	Lth1	Entry Brightness	cd/m2	Tunnel entry brightness design value
Constant	LLF	Maintenance Coefficient		System maintenance coefficient, which needs to be updated periodically according to the design requirements

2.3.4 Configure Strategy Rules

1. Configure available trigger conditions: Click the Condition Edit button in the upper right corner of the specification area, and then select the rules conditions that need to be used.

   

2. Configure trigger rules: Select the add button, add a rule, and then configure the corresponding trigger conditions according to the different types of condition parameters.

   

   

   

   

3. Configure the device status under the specified rule conditions
