Illuminating system for refrigeration storage

Abstract

The invention relates to an illuminating system for a refrigeration storage. The illuminating system comprises a plurality of LED (light emitting diode) lamps (27) mounted in the refrigeration storage, an LED lamp control device, a PLC (programmable logic controller) controller, a control computer and a computer network. The LED lamp control device is used for controlling and driving the LED lamps and comprises an MCU (micro controller unit), a power line carrier demodulation receiving unit, an address code unit (22) and an LED drive unit, wherein the power line carrier demodulation receiving unit is electrically connected with the MCU, and the address code unit (22) corresponds to the LED lamp control device. The PLC controller is in network connection with the LED lamp control device through a power line and used for controlling the LED lamp control device and comprises a master control chip (31), a power line carrier demodulation transmission unit, a key / option switch and a communication interface (32), and the power line carrier demodulation transmission unit is electrically connected with the master control chip (31). The computer and the computer network are externally and electrically connected with the PLC controller. The illuminating system for the refrigeration storage has the advantages that by means of LED lighting, power line carrier and intelligent control, electricity consumption for illumination and refrigeration storage is greatly reduced, and convenience in mounting and simplicity in control are achieved.

Description

technical field [0001] The invention relates to intelligent lighting and cold storage management, in particular to a cold storage lighting system. Background technique [0002] Cold storage is mainly used for constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments, etc. General cold storage equipment is mostly refrigerated by a refrigerator, using a liquid with a very low vaporization temperature (ammonia or freon) as a coolant to evaporate it under low pressure and mechanical control conditions, absorbing the heat in the storage, so as to achieve cooling and cooling the goal of. The most commonly used is the compression refrigerator, which is mainly composed of a compressor, a condenser, a throttle valve and an evaporation tube. According to the way of evaporating tube device, it can be divided into direct cooling and ind...

Problems solved by technology

[0003] The lighting in cold storage used to be basically sodium lamps. This kind of air discharge lamp will emit relatively large heat when it is lit. Because of its low conversion efficiency, the lost power will be emitted in the form of heat, resulting in an increase in the temperature in the cold storage. , at this time the compressor in the cold storage will continue to work, and the power consumption will increase

At the same time, the lighting in the cold storage does not need power at all times and always maintains the same brightness, which will also cause unnecessary power consumption
