It is overlapping with being operated outside piece that operation in piece may be implemented there are one primary pipeline organization in tool.
In the present invention, remote terminal 8 is made of operating system, monitoring software, application of function software, in an operating system,
Using real-time multi-task operating system (RTOS), RTOS be the basic and development platform of embedded application software, China is big at present
Most embedded software developings are still directly write based on processor, cannot be by system software not using the RTOS of commercialization
It is separately handled with application software.RTOS is one section of software being embedded in day mark code, and the other applications of user are all established
On RTOS.The very high real-time kernel of RTOS or reliability, all by resources such as CPU time, interruption, I/O, timers
It wires up, leaves one standard API of user for, and according to the priority of each task, reasonably distributed between different task
CPU time.Various hardware drive programs, expert's library function, industry library function, product library letter can be write out on the basis of RTOS
Number.It is that RTOS sets the main line of juice from start to finish expeditiously to carry out multitask support, can be united using RTOS management system
One assists each task of withering, and optimizes the distribution of CPU time and system resource, is allowed to not idle, not congestion；And monitoring software includes connecting
It is connected to the communication interface driving of communication system, the device drives of connection scene I/O equipment, scanning, the processing at SCADA regulation and control center
（Filtering and calibration calculating etc.）, storage field data, signal transmission：Regulate and control center with SCADA system or exchanges letter with other RTU
Breath regulates and controls the response of central command, the control of Field adjustment system to being transmitted through the SCADA come from communication network, and pid loop control is
Most basic mode, some complex regulating systems be also by pid loop control based on, logical order control, such as wiper
Transmitting-receiving control, the start-up and shut-down control of pump group, crane tube load control, oil tank switch flow switching etc. and belong to such, equipment autodiagnosis
It is disconnected, program self- recoverage, fault diagnosis to plug-in unit grade, man-machine interface：Including keyboard, button, display screen etc. and alarm and automatically
Protection is handled；As for application of function software section, then different according to application production object, manufacturer's exploitation is much different to answer
With the matched operation of program.
The photoelectricity smoke alarm that the present invention uses dissipates the smog that principle generates Initial Stage of Fire using light and detects,
And alarm signal is sent out in time.According to the difference of light source, can be divided into general photo-electric, laser light electric-type, ultraviolet light photo-electric with
And four kinds of infrared light photo-electric etc..Specifically, in general photo-electric, in the case that smokelessly, the light that light source is sent out passes through lens
It is polymerized to light beam, is irradiated on photoelectric cell, and is converted into electric signal, entire circuit is made to maintain in normal state, not send out
Go out alarm.When there is fire generation, there is smog into row detector, so that the propagation performance of light is changed, light intensity obviously weakens, circuit
Normal condition destroyed, then send out alarm signal.Laser room smoke alarm also can be used in the present invention, i.e., by Laser emission
Machine（Including the pulse power and laser emitter）And laser pickoff（Including photelectric receiver, pulse amplifying and alarm）Composition,
The feature that, brightness strong using laser direction is high and monochromaticjty goes with coherence, in the case that smokeless, pulse laser beam is mapped to light
On electric receiver, it is converted into electric signal, alarm does not send out alarm, once laser beam has smog to block and subtract in emission process
It is weak to a certain extent after, so that photelectric receiver signal is obviously reduced, detector sends out alarm signal.The present invention also can be used ultraviolet
Light and infrared light smoke alarm, the realization method of smoke alarm of the present invention is not unique, has a variety of realization methods.
In the present invention, one in two thermistors 5 can direct feeling environment temperature variation, and another is then sealed
It closes in bead with a certain amount of heat, when ambient temperature variation is slow, the resistance value of two thermistors 5 is with environment temperature
Variation is wanted to approach substantially, and switching circuit is failure to actuate.When fire occurs, environment temperature is ramping up, the resistance value of two thermistors 5
Change inconsistent, original stable state to destroy, switching circuit is opened, and alarm signal is sent out.
It glows the stage since Initial Stage of Fire exists, will produce a large amount of cigarette and a small amount of heat, very little or none Fire Radiation,
Smoke alarm intervenes work；Fire development is rapid, generates a large amount of cigarette, heat and Fire Radiation, at this point, by the temperature in the present invention
Sense is used cooperatively with cigarette sense, is formed the unpredictable characteristic of feature and alarm according to fire, is reduced fire to greatest extent
Casualties and economic loss.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe the originals of the present invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
