Piezoelectric traffic traffic Sensor ya AVC (Ibyiciro byimodoka byikora)

Ibisobanuro bigufi:

CET8311 sensor yumuhanda yubwenge yagenewe gushyirwaho burundu cyangwa byigihe gito kumuhanda cyangwa munsi yumuhanda gukusanya amakuru yumuhanda. Imiterere yihariye ya sensor ituma ishobora gushirwa munsi yumuhanda muburyo bworoshye bityo igahuza imiterere yumuhanda. Imiterere iringaniye ya sensor irwanya urusaku rwumuhanda ruterwa no kugunama hejuru yumuhanda, inzira zegeranye, hamwe nimiraba yunamye yegera ikinyabiziga. Gucisha make kuri kaburimbo bigabanya kwangirika hejuru yumuhanda, byongera umuvuduko wo kwishyiriraho, kandi bigabanya ingano ya grout isabwa mugushiraho.

Intangiriro

Ibyiza bya CET8311 yubushishozi bwumuhanda ni uko ishobora kubona amakuru yukuri kandi yihariye, nkikimenyetso cyihuta cyukuri, ibimenyetso byerekana ibimenyetso hamwe namakuru yo mu byiciro. Irashobora gusubiza amakuru yumuhanda imibare ndende, hamwe nibikorwa byiza, kwizerwa cyane no kwishyiriraho byoroshye. Imikorere ihenze cyane, ikoreshwa cyane mugushakisha umubare wumurongo, ibiziga, kugenzura umuvuduko wibinyabiziga, gushyira ibinyabiziga, gupima imbaraga hamwe n’ahantu nyabagendwa.

Muri rusange

Ex: L = metero 1,78; Uburebure bwa Sensor ni metero 1.82; Muri rusange uburebure ni metero 1.94

Gutegura

Guhitamo igice cy'umuhanda:
a) Ibisabwa ku bikoresho bipima: Igihe kirekire kandi gihamye
b) Ibisabwa kumuhanda: Rigidness

Uburyo bwo kwishyiriraho

5.1 Ahantu ho gutema:

Intambwe

Ishusho

1） Ibyapa byo kuburira bigomba gushyirwa imbere yubwubatsi.2） Gushushanya umurongo: koresha kaseti, ikaramu yerekana ikaramu hamwe nisoko ya wino kugirango ushushanye kandi ushire akamenyetso aho sensor yashyizwe, kandi urebe ko insinga ari ndende bihagije kugirango uhuze kumuhanda Inama y'Abaminisitiri.3） Ahantu ho gukata: koresha icyuma kugirango ufungure umurongo wa kare kumuhanda ugana kumurongo. Ibipimo byambukiranya ibice bigomba kugenzurwa neza murwego rwagenwe (reba igishushanyo kuruhande). Ukurikije uburebure bwa sensor, ongera ubujyakuzimu bwa shobuja kugeza kuri 50mm (kugirango uhuze na sensor isohoka umutwe nimpera).

4 break Guhagarika umuhanda:use inyundo yo gutobora no gutunganya hepfo yigituba. Hasi ya groove igomba gutondekwa neza bishoboka.

Ukurikije igishushanyo: ishusho iboneye hamwe nibishushanyo mbonera byubwubatsi.

Ibikoresho nyamukuru: imashini ikata pavement, ingaruka inyundo, isuka, imyitozo.

Icyitonderwa:

Igenzura ubujyakuzimu bwimbitse bwikibuga. Niba ari ntoya cyane, sensor na bracket ntibishobora kwicara. Niba ari ndende cyane, ingano ya groutBizaba binini.

groutBizaba binini.

1) Igipimo cyambukiranya

A = 20mm (± 3mm) mm；B = 30 (± 3mm) mm

2) Uburebure bwa Groove

Uburebure bwikibanza bugomba kuba burenze mm 100 kugeza kuri 200 z'uburebure bwa sensor.

Uburebure bwose bwa sensor:

i = L + 165mm, L ni uburebure bw'umuringa (Reba ikirango).

5.2 Sukura kandi wumye intambwe

1, Kugirango umenye neza ko ibikoresho byo kubumba bishobora guhuzwa neza nubuso bwumuhanda nyuma yo kuzuza, ahantu hashyirwaho hagomba gukaraba hamwe nogusukura umuvuduko ukabije, kandi hejuru yikibanza hagomba gukaraba hamwe nicyuma cyuma, hanyuma compressor de air / umuvuduko mwinshi imbunda cyangwa blower ikoreshwa nyuma yo koza kugirango yumishe amazi.

2, Nyuma yimyanda imaze gusukurwa, ivu rireremba hejuru yubwubatsi naryo rigomba gusukurwa. Niba hari amazi yegeranijwe cyangwa ubuhehere bugaragara, koresha compressor yo mu kirere (imbunda yo mu kirere ikabije) cyangwa blower kugirango uyumishe.

3, Nyuma yo gukora isuku irangiye, hashyirwaho kaseti (ubugari burenze 50mm)
kumuhanda hejuru yumuhanda kugirango wirinde kwanduza grout.

5.3Ikizamini cyo kwishyiriraho

1, Ubushobozi bwikizamini: Koresha metero nyinshi ya digitale kugirango upime ubushobozi bwuzuye bwa sensor hamwe numugozi ufatanije. Agaciro gapimwe kagomba kuba mumurongo wagenwe nuburebure buringaniye hamwe nurupapuro rwamakuru. Urutonde rwibizamini rusanzwe rushyirwa kuri 20nF. Umutuku utukura uhujwe ninturusu ya kabili, naho umukara wirabura uhujwe ningabo yo hanze. Menya ko udakwiye gufata amahuriro yombi arangirira icyarimwe.

2, Kurwanya Ikizamini: Gupima ukurwanya kumpande zombi za sensor hamwe na metero nyinshi ya digitale. Metero igomba gushirwa kuri 20MΩ. Muri iki gihe, gusoma ku isaha bigomba kurenga 20MΩ, ubusanzwe byerekanwa na “1”.

5.4 Gukosora imitwe

Intambwe

Ishusho

1） Kuramo sensor hanyuma urebe niba sensor idahwitse. Kuringaniza sensor kugirango ugumane sensor igororotse kandi iringaniye.2） Fungura igitereko cyo kwishyiriraho mu gasanduku hanyuma ushyireho brake hafi ya sensor hafi ya 15cm intera.3） Shyira igitereko cyo kwishyiriraho hamwe na sensor

mu gice cyo gukata. Ubuso bwo hejuru bwibice byose ni nka 10mm uvuye kumuhanda.

4） Hindura sensor irangire munsi ya 40 °, yunike ingingo munsi ya 20 °, hanyuma uyihe 20 ° hejuru kugeza kurwego.

Igipimo

5.5 Kuvanga grout

Icyitonderwa: Nyamuneka soma amabwiriza ya grout witonze mbere yo kuvanga.
1） Fungura inkono, ukurikije umuvuduko wuzuye hamwe na dosiye isabwa, irashobora gukorwa muke ariko inshuro nke kugirango wirinde imyanda.
2 are Tegura urugero rukwiye rwo kubumba ukurikije igipimo cyagenwe, hanyuma ubyerekane neza hamwe na firimu ya nyundo (hafi iminota 2).
3） Nyuma yo kwitegura, nyamuneka koresha muminota 30 kugirango wirinde gukomera mu ndobo.

5.6Icyiciro cya mbere cyuzuza intambwe

1） Suka igituba kiringaniye muburebure bwa groove.
2） Iyo wujuje, icyambu cyamazi gishobora gukorwa nintoki kugirango byorohereze kugenzura umuvuduko nicyerekezo mugihe cyo gusuka. Kugirango ubike umwanya n'imbaraga z'umubiri, birashobora gusukwa hamwe nibikoresho bito bito, byorohereza abantu benshi gukora icyarimwe.
3 filling Kwuzura kwambere kugomba kuba kuzuye ahantu huzuye, no gukora grout hejuru gato gato ya pavement.
4） Bika igihe gishoboka, bitabaye ibyo grout izakomera (iki gicuruzwa gifite igihe gisanzwe cyo gukiza cyamasaha 1 kugeza 2).

5.7Icyiciro cya kabiri cyuzuza intambwe

Nyuma yo guswera kwambere gukira, reba hejuru ya grout. Niba ubuso buri munsi yumuhanda cyangwa ubuso bwarashizwe hejuru, subiramo grout (reba intambwe 5.5) hanyuma ukore kuzuza kabiri.
Iyuzuzwa rya kabiri rigomba kwemeza ko ubuso bwa grout buri hejuru gato yumuhanda.

5.8 Gusya hejuru

Nyuma yo kwishyiriraho intambwe 5.7 irangiye kumasaha yigice, hanyuma grout itangira gukomera, yashishimuye kaseti kumpande zumwanya.
Nyuma yo kwishyiriraho intambwe 5.7 irangiye kumasaha 1, na grout ikomera rwose, gusya
guswera hamwe na gride ya angle kugirango itume hejuru yumuhanda.

5.9Ku rubuga rwogusukura no kugerageza nyuma yo kwishyiriraho

1） Sukura ibisigazwa bya grout nibindi bisigazwa.
2） Kwipimisha nyuma yo kwishyiriraho ：

. Agaciro gapimwe kagomba kuba mumurongo wagenwe nuburebure buringaniye hamwe nurupapuro rwamakuru. Urutonde rwibizamini rushyirwa kuri 20nF. Umutuku utukura uhujwe ninturusu ya kabili, naho umukara wirabura uhujwe ningabo yo hanze. Witondere kudafata amahuriro abiri arangirira icyarimwe.

(2) Kurwanya ikizamini: koresha metero ya digitale kugirango upime ubukana bwa sensor. Metero igomba gushirwa kuri 20MΩ. Muri iki gihe, gusoma ku isaha bigomba kurenga 20MΩ, ubusanzwe byerekanwa na “1”.

. Igenamiterere risanzwe rya oscilloscope ni: Umuvuduko 200mV / div, Igihe 50ms / div. Kubimenyetso byiza, imbaraga za trigger zashyizwe kuri 50mV. Ubwoko busanzwe bwikamyo hamwe nimodoka byakusanyirijwe hamwe mbere yo kwipimisha ibizamini, hanyuma ibizamini byo kubikwa bikabikwa hanyuma bikandukurwa kugirango bicapwe, kandi bikizwa burundu. Ibisohoka bya sensor biterwa nuburyo bwo kwishyiriraho, uburebure bwa sensor, uburebure bwumugozi nibikoresho byo kubumba byakoreshejwe. Niba ikizamini cya preload gisanzwe, kwishyiriraho birarangiye.

3) Kurekura ibinyabiziga: amagambo: Imodoka irashobora kurekurwa gusa mugihe ibikoresho byo kubumba byakize neza (amasaha agera kuri 2-3 nyuma yo kuzura bwa nyuma). Niba traffic irekuwe mugihe ibikoresho byo kubumba byakize bituzuye, byangiza kwishyiriraho kandi bitera sensor kunanirwa imburagihe.
