Abstract
The utility model provides an electric heating temperature monitoring controlling means, includes: temperature, electric current collection module, a data record storage module, data conversion and show module carry out data interchange through the CAN bus between the three module, and temperature collection module passes to data record storage module with gathering the indoor outer temperature of returning through the CAN bus in real time, electric current collection module passes current transformer with getting into indoor voltage line, and current transformer becomes the low current signal with high electric current signal conversion and gives digital ampere meter, and the ampere meter becomes the AD mouth that voltage signal transfered electric heating monitor control device with signal conversion again to the device changes analog signal to data signal, and preserve, the utility model discloses a collection module can in real time, in succession, accurately gather temperature value and current value to realize the record storage and the curve show of data. The device simple structure, low in production cost, data precision are high, the security performance is high, the bandwagon effect is convenient for understands, easily popularizes and applies.
Description
Technical field
This utility model relates to a kind of temperature monitor and control device being applied to electric heating field.
Background technology
Along with national energy-saving reduces discharging policy and the whole world extensive concern for low-carbon economy, electric heating becomes a kind of novel cleaning heating system.Heat supply in winter is the important process that northern area must be carried out when arriving in the winter time, and therefore electric heating system is widely applied at northern area.
At present, the temperature controller of electric heating system can realize the temperature of electric heating material and control, but can not realize temperature and the functions such as validity check is monitored and controlled in real time.Electric company, electric heating manufacturer need the variations in temperature of monitoring electric heating system in real time to judge electric heating power selection, design the most rationally, and power consumer is carried out the work such as Electrical Safety assessment and electric heating efficient studies simultaneously；And power consumer is more concerned with the whether economical rationality of electric heating power designs, whether heating effect meets requirement.
Utility model content
The purpose of this utility model be to provide a kind of electric heating system temperature monitor in real time, data record and draw curve control device, the data such as accurate acquisition metering current, temperature and time, realize data real time record, storage and curve and show function, carry out electric heating system efficient studies for electric company and manufacturer and electric heating system power designs provides data support accurate, efficient.
For achieving the above object, this utility model provides a kind of electric heating temperature monitor and control device, it is characterized in that including: temperature, a current acquisition module, one data record memory module, one data conversion and display module, data exchange is carried out by CAN, wherein between three modules:
The indoor and outdoor temperature that collection is returned by temperature collect module by DS18B20 temperature acquisition chip is uploaded to data record memory module in real time by CAN；Current acquisition module is will to enter indoor pressure-wire through current transformer, high current signal is converted into low current signal and gives digital ammeter by current transformer, ammeter converts the signal into voltage signal again and passes to the A/D mouth of electric heating monitor controller, so that analog-signal transitions to data signal, and is preserved by device；
Temperature value and current value that device is periodically gathered by data record memory module automatically carry out record storage by CAN, and temperature value is passed to the liquid crystal display of this module by RS232 bus；
Data conversion and display module are made up of transducer and displaying terminal, gather data and will draw out data recording curve by transducer, and are shown at displaying terminal.
This utility model effect is: electric heating temperature monitor and control device can collect temperature value and current value in real time, continuously, exactly by acquisition module, and realizes record storage and the curve displaying of data.This apparatus structure is simple, production cost is low, data precision is high, security performance is high, bandwagon effect readily appreciates, application easy to spread, data and curve can be simultaneously transferred to electric company, manufacturer and power consumer, provide effective technical support for carrying out the work of the data analysis such as electric heating efficient studies and electric heating system power designs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, between the indoor and outdoors of room sunny side, the indoor and outdoors of the back and room, 5 temperature acquisition points are laid in center.It is aerial that indoor temperature collection point is suspended in room away from 1.5 meters of ground, and not heat insulation with any or thermal dissipating object contacts.Outdoor temperature acquisition point delivers to outdoor by window, does not contacts with any thermal dissipating object.
The indoor and outdoor temperature that collection is returned by temperature collect module by DS18B20 temperature acquisition chip is uploaded to data record memory module in real time by CAN；Current acquisition module passes current transformer by entering indoor pressure-wire, and high current signal is converted into low current signal and gives digital ammeter by current transformer.Signal is become voltage signal and passes to the A/D mouth of electric heating monitor controller by ammeter again, in order to analog-signal transitions to data signal, and is preserved by device；Temperature value and current value that device is periodically gathered by data record memory module automatically carry out record storage by CAN, and temperature value is passed to the liquid crystal display of this module by RS232 bus；The data gathered will draw out data recording curve by the transducer in data conversion and display module, and be shown at displaying terminal.
Gather data and include date, time, back outdoor temperature, back indoor temperature, sunny side outdoor temperature, sunny side indoor temperature, average indoor temperature and current value.
Monitoring process is as follows: between the indoor and outdoors of room sunny side, the indoor and outdoors of the back and room, 5 temperature acquisition points are laid in center.It is aerial that indoor temperature collection point is suspended in room away from 1.5 meters of ground, and not heat insulation with any or thermal dissipating object contacts.Outdoor temperature acquisition point delivers to outdoor by window, does not contacts with any thermal dissipating object.
