Detailed Description
The technical scheme of the utility model is specifically explained below with reference to the accompanying drawings.
The utility model discloses a smoke alarm system of a lithium battery ship, which comprises a PLC control unit, and a smoke sensor, a display touch screen and a sound and light alarm unit which are connected with the PLC control unit; the smoke sensor is arranged in the lithium battery cabin; the PLC control unit is connected with the smoke sensor and the sound-light alarm unit through 485 interfaces, and is also connected with the display touch screen through RJ45 interfaces. The display device also comprises a 24V power module which is used for supplying power to the PLC control unit, the display touch screen and the sound and light alarm unit.
The sound and light alarm unit comprises a sound and light alarm and an output module which is connected with the PLC control unit and used for driving the sound and light alarm to work.
The smoke sensor comprises a light emitting diode, a phototriode, a resistor, a signal acquisition module, an embedded controller, an RS485 interface and a power supply module for supplying power to the smoke sensor, wherein the light emitting diode, the phototriode and the resistor are connected in series and are connected with the positive and negative input ends of the signal acquisition module, the output end of the signal acquisition module is connected with the embedded controller, and the embedded controller is also connected with a PLC control unit through the RS485 interface; the light emitted by the light emitting diode is irradiated on the phototriode.
The following is a specific example of the present invention.
As shown in the system architecture diagram of fig. 1, the smoke alarm system mainly comprises 4 parts, namely a smoke sensor, a PLC control system, a display touch screen, an audible and visual alarm system, and the like, wherein the PLC control system is used as a control core of the smoke alarm system and comprises a signal acquisition, analysis and calculation and output unit.
As shown in the electrical schematic diagram of fig. 2, set up the smoke transducer of certain quantity according to the actual conditions in lithium cell cabin, 2#485 communication interface through PLC gathers smoke transducer's signal, PLC control system passes through 485 communication connection output module, simultaneously through the net twine real-time with the communication of host computer touch-sensitive screen, wherein output module is connected with audible-visual annunciator, the smog condition appears in the battery cabin, this smoke alarm system will output signal drive audible-visual annunciator and report to the police and indicate, and show alarm information at the touch-sensitive screen display, for example smog warning quantity and alarm position etc..
As a core data source of the smoke alarm system, the continuous and stable operation of the smoke alarm system is very important, and as shown in the following fig. 3, a schematic diagram of the interior of the smoke sensor is shown, and the specific working principle is as follows: when the detected environment is clean and has no smoke, the light emitting diode D1 emits light with a set current, the light source with a certain intensity collected by the phototriode VT1 is in a conducting state, the stronger the illumination intensity is, the smaller the conducting resistance of the phototriode is, the stronger the current signal of the whole loop is, when the detected environment has smoke, the intensity of the light source collected by the phototriode is greatly reduced, the resistance value of the loop is increased, the current is reduced, the current change signal in the loop is analyzed and processed by the signal collection module and the controller, the final signal is converted into a 485 signal, and therefore the external system can collect the smoke condition of the detected environment through 485 communication and make corresponding measures.
The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
