Thermostat ine LED kuratidza
Iyo sisitimu inoshandiswa kuchengetedza imwe tembiricha muimba inodzorwa. Mune mhinduro yakarongwa, kushandura-kuvhenekera uye kudzima tembiricha yerelay inogadzika yakazvimirira, nekuda kwekuti iyo yekumisikidza zvingangoita zvisingagumi. Iyo thermostat inogona kushanda zvese mukudziya modhi uye mukutonhodza modhi nechero hysteresis renji. Nekugadzirwa kwayo, chete kuburikidza nezvinhu uye yakagadzirira-yakagadzirwa-yakagadzirwa tembiricha tembiricha sensor yakashandiswa. Kana zvichidikanwa, zvese izvi zvinogona kukwana muZ-107 kesi, iyo yakagadzirirwa kuiswa pane yakakurumbira TH-35 "yemagetsi" bhazi.
Schematic diagram ye thermostat inoratidzwa mufig. 1. Iyo sisitimu inofanirwa kupihwa nemagetsi anogara aripo angangoita gumi nemaviri VDC, yakabatana nekubatanidza X12. Inogona kunge iri chero sosi yemagetsi ine yazvino mutoro weinenge 1 mA. Diode D200 inochengetedza sisitimu kubva ku reverse polarity yevoltage yekupinza, uye capacitors C1 ... C1 ita sefa mains. Mhepo yekupinza yekunze inoiswa kune regulator U5 mhando 1. Iyo thermometer inodzorwa neU7805 ATmega2 microcontroller, yakavharwa nechiratidzo chewachi yemukati, uye basa re sensor tembiricha rinoitwa neiyo system mhando DS18B20.
Yakashandiswa kutaurirana nemushandisi matatu-manhamba LED kuratidza. Kudzora kunoitwa multiplexed, anodes ezviratidziro zvinobudiswa zvinofambiswa ne transistors T1 ... T3, uye cathodes inodzorwa zvakananga kubva ku microcontroller port kuburikidza nekumisa resistors R4 ... R11.
Kuti uise zvigadziriso uye zvigadziriso, iyo thermostat ine mabhatani S1 ... S3. Relay yakashandiswa sehurongwa hwekutonga. Paunenge uchityaira mutoro unorema, teerera kune mutoro pane relay contacts uye PCB tracks. Kuti uwedzere mutoro wavo, unogona kupinza matiraki kana kuisa uye solder waya yemhangura kwavari.
thermostat inofanira kuunganidzwa pamapuranga maviri edunhu akadhindwa, dhayagiramu yegungano inoratidzwa muMufananidzo 2. Kuungana kwegadziriro yacho kwakajairika uye hakufaniri kukonzera matambudziko. Inoitwa seyakajairwa, kutanga nekutengesa resistors uye zvimwe zvidiki-saizi zvinhu kudhiraivha bhodhi, uye kupera nekugadzwa kwe electrolytic capacitors, voltage stabilizer, relays uye screw connections.
Isu tinoisa mabhatani uye kuratidzwa pabhodhi rezvibodzwa. Panguva ino, uye zviri nani usati waunganidza mabhatani uye kuratidza, zvinodikanwa kusarudza kana uchida iyo thermostat ichaiswa mudzimba Z107.
Kana iyo thermostat ichaiswa seyakajairwa, senge pamufananidzo wemusoro, saka zvakakwana kubatanidza mahwendefa ese nekona bar yegoldpin pini. Maonero emahwendefa akabatanidzwa nenzira iyi anoratidzwa mumufananidzo 3. Zvisinei, kana tikasarudza kuisa thermostat muZ107 kesi, semufananidzo 4, ipapo imwe chete yakapfava 38 mm strip nemapini egoridhe ane socket yevakadzi inofanira kuva. inoshandiswa kubatanidza mahwendefa ose. Dhonza maburi matatu kumberi kwekesi yemabhatani S1…S3. Kuita kuti chimiro chese chigadzikane mushure mekusangana, iwe unogona kuwedzera kusimbaradza nesirivha-yakapetwa waya (mufananidzo 5), mamwe mapedhi anobuditsa anotenderera achabatsira pano.
Danho rekupedzisira tembiricha sensor kubatana. Nokuda kweizvi, chibatanidza chakanyorwa TEMP chinoshandiswa: tambo nhema ye sensor yakabatana nepini yakanyorwa GND, iyo yero waya kune pini yakanyorwa 1 W, uye tsvuku tsvuku kune pini yakanyorwa VCC. Kana tambo ipfupi, inogona kuwedzerwa uchishandisa yakamonyoroka peya kana shielded audio cable. Iyo sensor yakabatana neiyi nzira inoshanda nemazvo kunyangwe netambo yakareba inosvika makumi matatu m.
Mushure mekubatanidza magetsi emagetsi, mushure mechinguva, ikozvino kuverenga kukosha kwekushisa kuchaonekwa pachiratidziro. Kana iyo thermostat relay ine simba inoratidza kuvepo kwedoti munhamba yekupedzisira yeratidziro. Iyo thermostat inotora iyo inotevera musimboti: mune yekudziya modhi, chinhu chacho chinotonhodzwa otomatiki, uye mune inotonhorera modhi, inodziya yega.
