Abstract
The invention discloses a gas detection apparatus with an alarm lamp. The gas detection apparatus comprising a main power supply, an MCU unit, an LED unit, and an I2C unit is characterized in that the main power supply is connected with the MCU unit and the LED unit; and the MCU unit is connected with the LED unit and the I2C unit. According to the invention, the built-in MCU is used for controlling light alarming separately; and the light alarming signal is triggered based on an I2C bus communication protocol and the scintillation state of the alarming light can be changed randomly, so that a warning effect can be realized conveniently and rapidly.
Description
Technical field
The present invention relates to a kind of gas analyser, particularly relate to a kind of gas-detecting device with alarm lamp.
Background technology
Existing market is applied to the detector of gas detecting and does not generally possess warning function, and simply can carry out the collecting work of gas concentration.If like this needing additionally to connect acoustic-optic alarm when there being alarm condition to occur just can play the effect of warning.Not only waste financial resources but also assemble and maintenance all can have problems.Make warning instruction that blind spot occur, become potential safety hazard.
As can be seen here, a kind of detection device possessing warning function is released particularly important.
Summary of the invention
For the problems referred to above, it is an object of the invention to a kind of multi-way detecting analyser, control and monitoring system is anti-explosion alarming controller, every controller four tunnel monitoring gas analysis real-time status.Adopting a gas analyser, sample gas inlet can separate multichannel, every road configuration explosion-proof solenoid valve, and explosion-proof solenoid valve realizes automatically switching and manual switching pipeline function by controlling system with anti-explosion alarming controller.
In order to realize the purpose of the present invention, the technical solution adopted in the present invention is: a kind of gas-detecting device with alarm lamp, including main power source, MCU unit, LED unit, I2C unit；It is characterized in that: described main power source connects MCU unit and LED unit；MCU unit connects LED unit and I2C unit.
Described main power source connects MCU unit and LED unit respectively by power conversion unit.
It is provided with LED drive unit between described MCU unit and LED unit；I2C communication interface protected location it is provided with between MCU unit and I2C unit.
Described MCU unit is also connected with gas sensor unit.
Described MCU connects large power triode by the IO protective resistance on MCU unit, and large power triode connects LED protective resistance, and LED protective resistance connects LED unit.
The invention has the beneficial effects as follows: traditional audible-visual annunciator is generally node signal and triggers or current signal triggering mode, and triggering mode is single and triggering effect is general.The present invention adopts built-in MCU individually to control light and reports to the police.By I2C bus protocol, visual alarm is triggered, can arbitrarily change the flicker state of warning light, conveniently serve warning function.

Fig. 2 is MCU function connection diagram of the present invention；
Fig. 3 is that MCU of the present invention drives LED schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
Detailed description of the invention one:
A kind of gas-detecting device with alarm lamp, including main power source, MCU unit, LED unit, I2C unit；It is characterized in that: described main power source connects MCU unit and LED unit；MCU unit connects LED unit and I2C unit.
Described main power source connects MCU unit and LED unit respectively by power conversion unit.
It is provided with LED drive unit between described MCU unit and LED unit；I2C communication interface protected location it is provided with between MCU unit and I2C unit.
Described MCU unit is also connected with gas sensor unit.
Described MCU connects large power triode by the IO protective resistance on MCU unit, and large power triode connects LED protective resistance, and LED protective resistance connects LED unit.
Detailed description of the invention two:
As it is shown in figure 1, adopting 5VDC in the design is system main power source, 5VDC Power convert is 3.3VDC by main power source power pack.3.3VDC power supply is directly powered for CPU and peripheral control unit.LED power pack directly adopts system 5VDC power supply to power and so can ensure that the high brightness of LED.This design benefit has carried out effective isolated from power with to the supply terminals equipment in system again, and each road does not interfere with each other, if there is one of them power failure without the normal operation affecting other unit.
Detailed description of the invention three:
As shown in Figure 2; the I2C signal that in the design, MCU primary responsibility reception master control power supply provides drives the work of acousto-optic warning unit and sensors configured internal data; driving light alarm unit to realize actuation of an alarm by the IO of MCU in the design, LED drives protected location primary responsibility protection MCU and LED will not burn out or misoperation because of extraneous interference.In the design, the control to LED is completely, it is possible to the flashing mode that arbitrarily change LED light is reported to the police.
Detailed description of the invention three:
As it is shown on figure 3, the large power triode that in the design, we adopt drives LED specially, and it is furnished with the current limiting pressure-limiting resistance I/O port to LED and MCU and is effectively protected, place the not predictable mistake caused due to extraneous or internal reason and occur.
