China Intelligent Street Lighting Project Remote Monitoring Control Management System

I: Specification

The CH-L0101 loop controller is independently developed by our company. Aimed for industry lighting for warehouse and factory, buildings,stations, and the smart tunnel lighting control system, etc., to control the power supply of lighting fixtures through a human-machine interface, to collect data and monitor the status of the power supply loop.

The management of traditional lighting fixtures in factories, warehouses, buildings, and stations mostly adopts special personnel manual control and special personnel inspection status, which not only takes up a lot of manpower and material resources, but also has problems such as inadequate management and untimely management. For example, special personnel are required to switch lights every day, Even if time-space equipment such as time controllers and theodolites are used, it still cannot solve multi-time management, abnormal weather operations such as cloudy days, accidents and other incidents, and equipment operations on site are still required. Another example: rigid control methods, lighting scenes, only relying on personnel inspections to find faulty equipment, and unable to provide managers with timely and reliable operating data. In response to these problems, our company has launched this lighting control equipment that integrates data collection, fault monitoring, data processing, local manual control, remote control, automatic operation by settings, theodolite, and sensor linkage.

The equipment adopts RS-485 or LoRa communication method, the distance can reach 2000 meters in the open environment without repeater; the communication distance can reach 10,000 meters in the case of repeaters. At most, the equipment has single circuit power supply on-off control, each loop control current up to 30 A( resistive load).

1. Upper Terminal Description

2. Lower terminal description

3.  Indicator light

4. Button Description

5. Loop power On/Off Control Function

1). Control Priority Level

   High priority or Same Level can change the state of low priority or same level, while low priority can not change the state of high priority.

   The control mode corresponds to the following priorities.

2). Recovery Auto-Run Operating, Priority Level 1 (Highest Priority Level)

At this time, the state of priority Level 4 is executed regardless of the control state in which it was previously operated(the specific operation is performed according to the setting value at the time of installation).

a) The server or client remotely issues “Recovery Auto-Run” command.

b) Press the "Manual/Auto - Run" Button on the device panel

c) The overhaul switch issued "Recovery Auto-Run".

3). Local Manual Control, Priority Level 2 

Change the On-Off state of the loop through the loop button on the panel.; at this time, the control commands of priority 3 and priority 4 will not be executed if the manual command is executed.

4). Remote Operation Control, Priority Level 2

Remotely issue the control loop ON/OFF Commands through the Server or the Client ; at this time, the controlled loop will execute the manual command, and the control status of priority 3 and priority 4 will not be executed.

5). Overhaul Switch control (non-standard, need to be customized), Priority Level2

Issued the control loop on-off command through the Overhaul Switch; at this time, all loops will execute manual commands, and the control states of priority 3 and priority 4 will not be executed.

6). Illumination control (non-standard features, need to be customized), priority Level 3

 By receiving the illumination value, all loop on-off states are controlled; if there is no illumination value refresh within 30 minutes, the automatic running state is restored (this function is not standard configuration); if the illumination value is continuously refreshed, the control state of priority 4 will not be executed. Running this state needs to be set.

7). Priority Level 3-- Motion sensor control (non-standard features, need to be customized).

   Receive the moving state, control all loop conduction, delay a certain time to restore the automatic state, running this state needs to be set.

8). Priority Level 4 -- Latitude & longitude Control

Calculate the sunrise and sunset time through the set latitude and longitude values, the sunrise time will disconnect the loop, and the sunset time will close the loop. The on-off time can be fine-tuned by the sunrise and sunset offset time, the fine-tuning range is 30 minutes.

For priority 3 and 4 states, only one of the states can be executed, which one needs to be set when the equipment is installed, and can also be changed later.

9). Priority Level 4 -- Schedule Control

Through the set 6-segment timetable and on-off status, to control loop  on / off.

For priority 3 and 4 states, only one of the states can be executed, which one needs to be set when the equipment is installed, and can also be changed later.

10). Priority Level 4 -- Signal Control (non-standard features, need to be customized)

 When the control function is set to Signal control mode, the signal control function is effective;

 When the Signal Control is disconnected, the controlled loop power supply is disconnected; when the Signal Control value is closed, the controlled loop power supply is closed.

For priority 3 and 4 states, only one of the states can be executed, which one needs to be set when the equipment is installed, and can also be changed later.

6.  Data Collection

 Remotely or locally Read the loop status and Digital input port status collected by the device.

7. Electricity Consumption Metering

Internal integration of single-phase electric energy metering module to collect and record the power consumption of electrical equipment in the circuit.

8. Electric Parameter Collection

Collect and record the voltage, current, and active power of the power supply Circuit.

9. Fault Report

  Detect the Input and Output status of the power loop. When the output status of the loop power supply does not match the device control status, the power loop power supply failure is determined and reported to the human-machine interface device; for example: the loop device control status is closed, but the loop input If the line is abnormally disconnected, the device will detect an abnormal output, loop fault will be reported by the device at this time.

10.  Lamp Dimming

  With our loop dimming controller, it can control the brightness of the lamps and achieve the purpose of energy saving.

11. Emergency Operation Function

In the case of failures such as the control bus or the centralized controller, the state of the loop can be manually controlled locally through the switch button on the panel.
