Chikamu cheCHIMWE
1, kucherechedzwa kuri kuburikidza neimwe nzira yemuviri, kusiyanisa huwandu hweakayerwa ma paramita ndeeimwe chiyero, kuitira kuona kana akayerwa ma paramita akakodzera kana kuti nhamba yemaparamendi iripo. Muitiro wekuenzanisa uwandu husingazivikanwi hwakayerwa nehuwandu hwehuwandu hwemhando imwe chete, kusarudza kuwanda kwehuwandu hwehuwandu hunoyerwa nechikwata chakayerwa, uye kuratidza uhwu huwandu hwenhamba.
Mumunda we otomatiki uye kuona, basa rekuona harisi chete kuongorora uye kuyerwa kwezvakapedzwa zvigadzirwa kana semi-apedzwa zvigadzirwa, asiwo kuitira kuongorora, kutarisa uye kutonga maitiro ekugadzira kana kufambisa chinhu kuti chiite mune yakanyanya kunaka. mamiriro akasarudzwa nevanhu, zvinodikanwa kuona uye kuyera saizi uye shanduko yeakasiyana paramita chero nguva. Iyi tekinoroji yekuona-nguva yekuona uye kuyerwa kwemaitiro ekugadzira uye zvinhu zvinofamba zvinonzi zvakare engineering yekuongorora tekinoroji.
Kune marudzi maviri ezviyero: kuyerwa kwakananga uye kuyerwa kusina kunanga
Chiyero chakananga kuyera kukosha kwakayerwa kwemamita kuverenga pasina kana kuverenga, se: kushandisa thermometer kuyera tembiricha, uchishandisa multimeter kuyera voltage.
Chiyero chisina kunanga kuyera huwandu hwemuviri hunoverengeka hunoenderana nekuyerwa, uye kuverenga kukosha kwakayerwa kuburikidza nehukama hwekushanda. Semuenzaniso, simba P rinoenderana nevoltage V uye ikozvino I, kureva, P = VI, uye simba rinoverengerwa nekuyera voltage uye ikozvino.
Kuyera kwakananga kuri nyore uye kuri nyore, uye kunowanzoshandiswa mukuita. Zvisinei, mumamiriro ezvinhu apo kuyerwa kwakananga hakugoneki, kuyerwa kwakananga hakuna kukanganisa kana kukanganisa kwechiyero chakananga chikuru, kuyerwa kusina kunanga kunogona kushandiswa.
Pfungwa ye photoelectric sensor uye sensor
Basa re sensor ndere kushandura huwandu husiri hwemagetsi muhuwandu hwehuwandu hwemagetsi hune hukama hunoenderana hunoenderana, iyo inonyanya kushandiswa pakati peiyo isiri-yemagetsi uwandu system uye magetsi ehuwandu hwemagetsi. Mukuita kwekuona uye kutonga, iyo sensor chinhu chakakosha chekushandura mudziyo. Kubva pane simba rekuona, sensor inogona kukamurwa kuva marudzi maviri: imwe ndiyo simba rekugadzirisa simba, rinozivikanwawo se sensor inoshanda; Imwe yacho ndiyo simba rekushandura sensor, inozivikanwawo se passive sensor. Energy control sensor inoreva iyo sensor ichayerwa kuita shanduko yemagetsi paramita (senge kuramba, capacitance) shanduko, iyo sensor inoda kuwedzera inonakidza simba rekupa, inogona kuyerwa maparamita shanduko kuita voltage, ikozvino shanduko. Iyo simba rekushandura sensor inogona kushandura zvakananga shanduko yakayerwa kuita shanduko yevoltage uye yazvino, pasina yekunze yekukurudzira sosi.
Muzviitiko zvakawanda, huwandu husiri hwemagetsi hunofanirwa kuyerwa hausi iwo huwandu husiri hwemagetsi hunogona kushandura sensor, izvo zvinoda kuwedzera mudziyo kana mudziyo pamberi pe sensor inogona kushandura iyo isiri-yemagetsi huwandu hwakayerwa mu. isiri-yemagetsi yakawanda iyo sensor inogona kugamuchira uye kushandura. Chikamu kana mudziyo unogona kushandura yakayerwa isiri-magetsi kuita magetsi anowanikwa inzwa. Semuyenzaniso, pakuyera voltage nejeji rekudzivirira, zvinodikanwa kuti ubatanidze iyo strain geji kune elastic element yekumanikidza kutengesa, iyo elastic element inoshandura kudzvanywa kuita simba rekumanikidza, uye strain geji inoshandura simba rekumanikidza kuita kuchinja mukupikisa. Pano iyo strain gauge ndiyo sensor, uye elastic element ndiyo sensor. Zvese zviri zviviri sensor uye sensor zvinogona kushandura yakayerwa isiri-magetsi chero nguva, asi sensor inoshandura yakayerwa isiri-magetsi kuita inowanikwa isiri-magetsi, uye sensor inoshandura yakayerwa isiri-magetsi kuita magetsi.
2, photoelectric sensorinobva pane photoelectric effect, chiedza chechiedza mumagetsi emagetsi emagetsi, anoshandiswa zvakanyanya mukugadzirisa otomatiki, aerospace uye redhiyo uye terevhizheni uye mamwe minda.
Photoelectric sensors inonyanya kusanganisira photodiodes, phototransistors, photoresistors maCD, photocouplers, nhaka yephotoelectric sensors, photocells uye mapikicha emifananidzo. Tafura yemhando huru inoratidzwa mumufananidzo uri pasi apa. Mukushanda kwekushandisa, zvinodikanwa kusarudza yakakodzera sensor kuti uwane iyo yaunoda mhedzisiro. General sarudzo musimboti ndeiyi:high-speed photoelectric kuonekwadunhu, hupamhi hwemamita ekuvhenekera, ultra-high-speed laser sensor inofanira kusarudza photodiode; Iyo yakapusa pulse photoelectric sensor yezviuru zvakati Hertz uye yakaderera-kumhanya pulse photoelectric switch iri nyore dunhu inofanira kusarudza iyo phototransistor; Kunyangwe kumhanya kwekupindura kuchinonoka, iyo yekupikisa bhiriji sensor ine kuita kwakanaka uye iyo photoelectric sensor ine inopikisa midziyo, iyo photoelectric sensor mune otomatiki yekuvhenekesa dunhu remwenje wemugwagwa, uye inoshanduka inopikisa inoshanduka zvakaenzana nesimba rechiedza inofanira kusarudza. Cds uye Pbs photosensitive zvinhu; Rotary encoder, kumhanya ma sensors uye ekupedzisira-yakanyanya kumhanya laser sensors anofanirwa kubatanidzwa mafotoelectric sensors.
