Description
Technical field
The present invention relates to a kind of on-line monitoring instrument, and in particular to a kind of cooking fume on-line monitoring instrument, belong to environment prison
Control technical field.
Background technology
Bread is the staff of life, and with developing rapidly for national economy, the material life condition of common people is become better and better, food and drink enterprise
Industry is also more and more, and scope is also increasingly wider, and pollution of the food and beverage enterprise to atmospheric environment is increasingly severe.Throwing to food and beverage enterprise
Tell the main contents for having turned into urban environmental protection complaint.Although there are certain pollution prevention measure, part in most of enterprise
Enterprise is not processed as requested in order to cost-effective.Because number of the enterprise is more and dispersion, it is to be difficult to reach to depend merely on manpower
Real-time monitoring, Realtime Alerts, unattended requirement.Cooking fume on-line monitoring instrument precisely in order to meet environmental protection industry (epi) this
Specific demand and design, it generally comprises monitoring host computer, oil smoke probe and operating mode sensor, and the monitoring of its oil smoke collection, data adopt
Collection, treatment are transmitted in one, can be to indexs such as food and beverage enterprise oil smoke discharge concentration, clarifier running status, fan operation states
On-line monitoring is carried out, is environmentally friendly supervisory department so as to oil smoke concentration data be combined with oil smoke processing facility floor data
Authentic and valid oil smoke discharge situation is provided.The display of cooking fume on-line monitoring instrument of the prior art and control program are all
Small size liquid crystal display collocation key board or large scale touch LCD screen two schemes are employed, while display unit is all integrated in
On main computer unit.The configuration of existing cooking fume on-line monitoring instrument device parameter needs external notebook computer or use
The mode of operation of mobile phone wireless connection configuration, it is relatively complicated；
Cooking fume on-line monitoring instrument of the prior art has all supported two kinds of communication modes of Ethernet and wireless communication networks.When
Typically using the side of external DTU, wireless router or built-in wireless communication module when being carried out data transmission using wireless communication networks
Case.External DTU can take serial digital amount interface all the way, and external wireless router can take Ethernet interface all the way, and data are passed
Defeated stability dependency is restricted to TCP connection numbers in DTU or wireless router, and the built-in protocol stacks of DTU；Using built-in nothing
Physical interface all disunities of the communication module that the oil smoke on-line monitoring instrument of line communication module is used, when carrying out network formats upgrading
