Dust detection alarm processing systemTechnical field
The present invention relates to dust detection alarm processing system.
Background technology
The industrial undertaking of China in metal cutting, weld, the production process such as condensation often give off a large amount of particulate matter, trickle grit residence time in atmosphere is the longest, and the probability being absorbed by the body is the highest.The employee of direct long term contact suffers from the probability hundreds times to be exceeded than normal person of respiratory tract disease and cancer.The whole nation over 10 years Pneumoconiosis Patients constantly rise.On the other hand, when dust arrives finite concentration, run into naked light and can produce blast, there is the strongest destructive power and easily cause subsequent explosion.And existing technology can not accomplish to detect the dust concentration of whole Factory Building, once ignores the dust concentration in certain corner, and is susceptible to the security incident of seriousness.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that one can monitor workshop dust concentration for 24 hours, and can carry out the processing system of Realtime Alerts according to dust concentration.
In order to realize the problems referred to above, the present invention is achieved by the following technical solution:
A kind of dust detection alarm processing system, including information gathering system, data transmission system and supervisory systems, information gathering system comprises information acquisition unit and information process unit, data transmission system includes 2 emitters, data transmission system is by cable and information gathering system wired connection, and for wireless connections between emitter and emitter, data transmission system and supervisory systems are wired connection.Described supervisory systems utilization 3G MODEM equipment is as short message sending equipment, to assigned number continual transmission alarming short message.
As technical scheme, information gathering system has acoustic-optic alarm.
As technical scheme, information process unit uses ARM V7 framework.
As technical scheme, it is 1 minute that SMS alarm sends interval time.
As technical scheme, supervisory systems can carry out emergent management measure by short-message instruction.
The invention has the beneficial effects as follows:
1, it is running in 24 hours due to this system, it is possible to the in real time dust concentration situation in each corner in detection Factory Building, it is ensured that can synchronize for 24 hours to receive dust concentration situation report.The precautionary measures can be carried out in advance by the dust concentration situation in each corner is carried out data staging, collects
2, this system has safe early warning effect, when the data detected exceed set restriction, can produce sound and light alarm, and can repeat to send warning message to related personnel by modes such as notes, until after related personnel intervenes, reporting to the police and just can stop.
Accompanying drawing explanation
Below in conjunction with concrete drawings and Examples, the present invention will be further described.
Fig. 1 is the system diagram of the present invention.
Dust detection alarm processing system 1 includes information gathering system 2, data transmission system 3 and supervisory systems 4.Wherein information gathering system 2 comprises information acquisition unit 5 and information process unit 6.Data transmission system 3 includes emitter 7 and emitter 8, and data transmission system 3 is wireless connections by cable A and information gathering system 2 wired connection, emitter 7 with emitter 8, and data transmission system 3 and supervisory systems 4 are wired connection.
nullInformation acquisition unit 5 is by dust sensor 9、Temperature sensor 10、Humidity sensor 11、Baroceptor 12、Wind pressure sensor 13 forms，Each sensor in information acquisition unit 5 is connected with information gathering system 2 by cable A respectively，Analog information that each different types of sensor probe is detected by information gathering system 2 by information acquisition unit 5 or digital information transmission are in information process unit 6，Analog information or digital information are wholly converted into digital information by the program unification of internal composition by information process unit 6，And carry out Unified coding，Simultaneously，Information gathering system 2 adds acousto-optic warning unit 14，The restriction numerical value of a certain sensor that a certain information once processed in information process unit 6 is arranged higher than PC end 10，Then acousto-optic warning unit 14 carries out audible alarm and light beam is reported to the police.Emitter 7 by receive by information process unit 6, the data of Unified coding are sent to emitter 8 wirelessly in, the data received are transferred in supervisory systems 4 by the way of wired by emitter 8, and supervisory systems 4 is made up of a pc end 10 and multiple stage mobile phone 11.The data received are transferred in multiple stage mobile phone 11 by the way of GPRS by PC end 10.The data that supervisory systems 4 can detect with all sensing points of real time inspection, the most a certain sensing point numerical value is higher than limit value, can constantly repeat to send relative alarm information until terminal check receives relevant information and then terminates to send.
Information process unit 6 uses Cortex-M3 and uses ARM V7 framework, has super many peripheral hardwares.Have and include: numerous peripheral hardware such as FSMC, TIMER, SPI, IIC, USB, CAN, IIS, SDIO, ADC, DAC, RTC, DMA and function, all input/output informations all use up-to-date magnetic coupling isolation technology, the input information of system simulation amount uses the low-power consumption of high-acruracy survey application, low noise, full simulation front end, built-in 18 ∑s of a low noise-Δ type ADC, wherein contain the input of multiple difference analogue, also it is integrated with low noise instrument amplifier in sheet, little information can be directly inputted.The minor variations of external information can be reflected in time.And in conjunction with have employed big electric current and the high speed characteristics of metal-oxide-semiconductor of relay, being suitable for different occasion sound and light alarm and controlling and the control of equipment.
Use 3G MODEM equipment as short message sending equipment, use the source code program write voluntarily to carry out to the phone number specified and send warning message, in the source code program write voluntarily, set interval time as 1 minute, and set and receive the content that the cell-phone number of note needs to reply.The restriction numerical value for each sensor that information process unit is arranged by supervisory systems 4 is analyzed, once find a certain sensor values and i.e. send alarm content by short message sending equipment to the phone number specified higher than the numerical value that limits set, if this cellphone subscriber does not replys or expression has been received by note the most in other ways, then short message alarm system is not stopped paying out to this subscriber phone number with the speed of each minute according to the program of default and is sent alarm content, until this user acknowledges receipt of note and makes and reply then system accordingly and stop sending note.After system receives note, carried out judging whether the note response that the phone number being required is made by system, if system is judged as "Yes", then system makes corresponding emergent management measure according to short-message instruction, controlling to intervene on-the-spot workshop condition at once by accelerating the means such as blower fan rotation or power-off, Accident prevention occurs.
Embodiment described above only have expressed one embodiment of the present invention, and it describes more concrete and detailed, but therefore can not be interpreted as limitation of the scope of the invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, therefore, protection scope of the present invention should be as the criterion with claims.
