Street lamp remote monitoring system

1、 Overview

The street lamp remote monitoring system has been uniformly managed by the municipal department, and the lamp power consumption has always ranked first in the power consumption of public facilities; Due to the time control mode, the switching time limit of street lamps is relatively dead. Whenever there are important activities or cloudy days, the line of sight is poor, and the switching time of street lamps cannot be advanced or delayed; Many times, the failure of street lamps can not be found in time, which affects the maintenance. The street lamp remote monitoring system enables managers to remotely control the switch of street lamps in the monitoring center; Automatically calculate the lighting rate and find faults in time.

2、 System composition

The system consists of monitoring center, communication platform, monitoring equipment and street lamp switchgear

Monitoring center: it is composed of server, GPRS data transmission module, monitoring system software, etc.

Communication platform: gprs-apn private network of China Mobile.

Monitoring equipment: street lamp measurement and control box.

Street lamp switchgear: switch of time controlled street lamp. (original equipment)

(1) . monitoring center

The monitoring center equipment is mainly composed of data server and data-6101gprs data transmission module (desktop). The server and GPRS module are connected by serial port cable, and the operating system software, database software and monitoring system software are installed on the server. The software has many functions, such as active inquiry, data display, data storage, data query, alarm display, calculation of light on rate, generation of curve report and so on.

(2) . communication equipment

China mobile GPRS network APN private network.

(3) . monitoring equipment

GPRS data transmission module, electric parameter acquisition module，Switching power supply, standby power supply, relay Solar panel, battery pack

3、 System function

(1) active inquiry function: the monitoring center can actively inquire about the switching state, current, voltage and electric quantity data of each street lamp.

(2) active control function: the monitoring center can switch any street lamp at will.

(3) automatic control function: automatically adjust the on-off time of street lamps on site according to seasonal changes, and turn on and off street lamps on time.

(4) alarm function: when the communication is interrupted, the lighting rate is too low and the switch is not on time, the monitoring center will have an alarm display.

(5) display the status and other important functions of each road lamp on the map.

(6) data storage function: store historical records in the database on the site monitoring equipment and server.

(7) data query function: the monitoring center can query the data information of each street lamp in any time period.

(8) curve report function: it can generate analysis curves and reports of current, voltage, electric energy, lighting rate and switching time.

(9) remote maintenance function: the acquisition and communication module in the monitoring equipment has the function of remote parameter setting and maintenance.

(10) expand functions: the system can freely increase or decrease the number of monitoring equipment. The monitoring equipment can expand other functions.

4、 Technical indicators

(1) central data server: CPU: P Ⅲ, above 1GHz; Memory: more than 128MB; Hard disk: above 40g.

⑵ GPRS data transmission speed: above 40kbps

(3) electrical parameter acquisition accuracy: 0.5%

(4) switching value acquisition speed: 1000 times / second

(5) working environment of monitoring equipment: strong GPRS signal; Ambient temperature: - 20 - + 70 ℃; Humidity ≤ 90%, no condensation, corrosive gas and conductive dust, and no explosive dangerous goods. There is 220V AC power supply.
