Abstract
The utility model relates to a calorimeter used in building and housing heating systems. The utility model is composed of a water meter, a temperature sensor, a signal processing circuit and a displayer. The utility model is characterized in that a digital temperature sensor is arranged in a water inlet and a return water pipe, a display device and a detection part are separately installed, and two magnetic induction press keys are hidden in the displayer. Due to the adoption of digital temperature sensor, the utility model has the advantages of high stability, wide temperature measurement range, and high precision. The display device and the detection part are separately installed and are installed outdoors, the magnetic induction press keys are hidden in the displayer, and the utility model can matched with a small magnet held by meter reading personnel. Needed information can be called out at any time, and the utility model is convenient for meter reading and meter checking. The utility model can also discover thermal burglary phenomenon.
Description
The utility model relates to a kind of calorimeter that measures the actual consumption heat in the heating system of building, dwelling house.
Existing in the market calorimeter, hot water flow adopts general teletransmission gear type wet-type meter or dry-type meter, on the water meter gear, magnet steel is housed, on the glass dial plate Magnetic Sensor is installed, obtain electric signal corresponding to hot water flow, the temperature of heating hot water and backwater is carried out thermometric by installation copper or platinum resistance thermometer sensor, temperature probe on the pipeline of hot water and backwater, the temperature signal that is recorded by flow electric signal and temperature probe amplifies, calculates, handles, and shows institute's consumption of calorie by display board.Because present calorimeter has adopted the temperature probe of resistance-type, its circuit conversion complexity is added the temperature variant influence of conductor resistance, easily causes the measuring error of system; Owing to present calorimeter line construction complexity, the signal transmssion line that is transferred to display is more again, brings difficulty for display and the partial installation of heat test section, display places on the case of water meter, therefore, calorimeter is loaded on indoor, brings difficulty to the meter reading personnel.
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of digital temperature probe that is equipped with to be provided, test section and the remote partial installation of display, and have the calorimeter of antitheft thermal information, warning function.
The technical solution of the utility model is achieved like this, heat test section and display two parts that it is made up of water meter, temperature probe, signal processing circuit are formed, be characterized in, be built-in with at heat water inlet and returned cold waterpipe and temperature signal can be directly changed into binary digital temperature probe; Display part and the remote partial installation in test section; In the case of display, keep two magnetic induction buttons.
Adopted digital temperature probe, therefore, good stability, temperature-measuring range is wide, the precision height, display part and the remote partial installation in test section, display is loaded on outdoor, and the built-in magnetic induction button of hiding, the small magnet that it and meter reading personnel hold matches, needs information can be accessed, be convenient to heat supply department and check meter, but also whether inspection user have robber's thermal phenomenon.
The utility model embodiment is described further in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model circuit theory diagrams.
By shown in Figure 1, this calorimeter is by water meter 5, digital temperature probe 7,9, the heat test section that signal processing circuit board 1 is formed and place outdoor display 11 two parts to form, the tongue tube 3 composition Magnetic Sensors that are equipped with on magnetic pointer 4 and the glass dial plate are being housed on water meter 5 gears, so just obtain the electric signal of hot water flow, digital temperature probe 7,9 respectively the fastening by separately be contained in returned cold waterpipe 6 and the hot inlet channel 10, fastening is by double thread web member 17, sleeve pipe 18, nut 19 and compressing member 20 are formed, double thread web member 17 lower ends are screwed in into water, on the water return pipeline, two digital temperature probes are DS1820, be packaged in the sleeve pipe 18, compressing member 20 is enclosed within on the lead, double thread web member 17 upper ends are screwed with nut 19, compressing member 20 compacted contractions like this, thereby it is stuck lead, prevent that temperature probe is pulled out, measure the temperature of heating hot water and backflow cold water reliably through the temperature probe of installing like this, and directly be directly changed into binary digital signal, by cable 8,14 transfer in the signal processing circuit board 1 that has microprocessor in the watchcase 2, by it to flow, the data of temperature are gathered, computing, handle, make instrument have the demonstration integrated flux, instantaneous delivery, the accumulation heat, instantaneous heat, the heating hot water temperature, return water temperature, temperature difference, antitheft thermal information, fault alarm etc., these information transfer to outdoor display 11 by cable 13, keep two magnetic induction buttons 15 in the case of display 11,16, this two buttons user can't operate, heat supply department is when checking meter, with with two magnetic induction buttons 15,16 small magnets that match, above-mentioned various information can be accessed, when checking meter, also can check is to have not steal thermal phenomenon.It is that microprocessor passes through flow signal that antitheft hot merit can detect, the detection of heating hot water temperature, return water temperature has reached that making software realizes: 1, flow signal is arranged, and the difference of heating hot water temperature, return water temperature is tending towards at 0 o'clock, can judge whether the user extracts temperature probe.2 if detect return water temperature be higher than the heating hot water temperature, can judge then whether the user changes two temperature probes.3, do not have signal if detect heating hot water temperature, return water temperature, can judge that then the user might cut off one of them temperature probe cable or two temperature probe cables are all cut off.
By shown in Figure 2, the utility model circuit is by operational amplifier U3, temperature probe U5, U6, microprocessor U1, E
2PROM U2 and LCD driver U4 form.Its principle of work is as follows, and current potential promptly enters the heat trace routine on the instrument after self check, detects the temperature and the flow signal that obtain by temperature probe and Magnetic Sensor and calculates heat through microprocessor, and result of calculation sent put display and show.When if instrument is changed battery, microprocessor disappears in case find supply voltage by the detection to cell voltage, and microprocessor deposits current data in E immediately
2PROM.
