Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lighting systems, in particular to an emergency lighting demonstration system for training. Background Art
[0002] Conventional lighting equipment usually uses two sets of independent lamps for normal lighting and emergency lighting respectively, and is equipped with two sets of drive circuits accordingly. During normal lighting, one set of lamps is controlled to perform lighting under normal conditions. When power is off, the emergency drive circuit is started and controls the other set of emergency lamps for lighting.
[0003] However, the use of two sets of independent lamps for lighting has the problem of high lamp cost. At the same time, during the actual power outage, the emergency driving circuit drives the emergency lamp to start the emergency, and most of the time it is ineffective lighting due to no one passing by. That is, within the corresponding environment, regardless of whether there is a human body, the emergency lamp always remains lit, and the emergency process cannot be intelligently controlled, resulting in increased power consumption of the corresponding lighting driving circuit and reduced emergency lighting life.

The double-pole switch is used to control the on and off of the branch a and the branch b, the other end of the double-pole switch is connected to one end of the resistor, and the other end of the resistor is connected to the negative pole of the power supply, and the detection and display system and the double-pole switch are electrically connected to the PLC controller.
[0006] Preferably, the lighting system includes a buzzer and a relay coil, one end of the buzzer is connected to the positive pole of the power supply, the other end of the buzzer is connected to the relay coil, the other end of the relay coil is connected to node a, and the normally open contact of the relay coil is connected in series to the power supply circuit of the emergency lighting.

[0008] Preferably, the first light emitting diode is a green light emitting diode.
[0009] The utility model has the following advantages: when the utility model does not need emergency lighting, the PLC controller controls the double-pole switch to be connected to branch b, so that the detection and display system displays its status, which is convenient for personnel to check whether the demonstration system is normal, and at the same time detects the smoke content in the air in real time. When it is detected that the smoke content in the air exceeds the threshold, the PLC controller controls the double-pole switch to be connected to branch a, and the lighting system is powered for lighting, thereby intelligently controlling the emergency lighting and improving the emergency lighting demonstration time.
