With the rapid development of science and technology, voice-activated switches have entered millions of homes, providing people with great convenience at night. For voice-activated switches, many people want to understand its characteristics and installation procedures. The following Xiaobian gives you a brief introduction to this aspect. I hope to help you!
What are the characteristics of voice-activated switches ?
1, sound start-up
As long as a certain sound is generated by hand or other means (such as whistling, shouting, etc.) near the switch, the voice switch will immediately turn on the light and be handy.
2, delay from off
Once the switch is turned on, the switch will be automatically turned off after a delay of several tens of seconds. This can reduce the unnecessary waste of electrical energy and is convenient and practical.
3, delay appliance life
The voice-activated switch can control the circuit using electronic components and contactless contacts to eliminate wave currents and sparks.
4, energy saving and environmental protection
The voice-activated switch is an automatic lighting switch that integrates acoustics, optics and time delay technology. It is widely used in corridors, building corridors, factories, gardens and other places. It is a modern and ideal new green lighting switch, and extends the service life of the lamp. Can save electricity.
What are the voice-activated switch installation steps?
1. The original switch is dismantled: The original switch and attached device are to be dismantled, and the installation and wiring conditions should be carefully observed before disassembly to avoid the switch being damaged due to blind disassembly.
2, clean up:
(1) Remove the debris from the junction box with a brush, and clean the debris on the thread head.
(2) If the inner surface of the metal junction box is rusted, the anti-rust paint should be promptly brushed after rust removal. The debris in the box should be cleaned.
3, wiring:
(1) The contact is reliable and the operation is flexible.
(2) The wire insulation resistance test is qualified and there is an insulation resistance test record.
4, installation:
(1) Leave the wire removed from the box for the length of the repair, cut the insulation, and take care not to injure the wire core.
(2) Coil the wire in the clockwise direction on the corresponding terminal of the switch, then tighten the head.
(3) If it is a single core wire, insert the wire core directly into the wire hole. When the hole diameter is greater than 2 times the wire diameter, it should be bent back into the wire hole and then pressed with the top wire. Note that the wire core should not be exposed.
5, power running:
(1) After the voice-activated switches have been installed, the insulation test of each branch shall be performed first, and check whether there is any open circuit, short circuit and insulation damage in the switch assembly.
(2) After passing the insulation test, it shall be transmitted step by step in sections.
Edit Summary: The above is the switch which features the voice, the voice switch installation steps which have relevant knowledge introduction, I hope we can learn from. Voice-activated switches are used more often in life, so information about them can be introduced to you and you can use them in the future.
Voice control switch
Traffic safety facilities refer to the collective name of facilities such as pedestrian underpasses, footbridges, lighting equipment, guardrails, posts, signs, and markings along the roads to ensure the safety of traffic and pedestrians and give full play to the role of roads. Traffic safety facilities include: traffic signs, markings, guardrails, barriers, outline markings, guidance markings, anti-glare facilities, etc.
Traffic safety facilities mainly include traffic signs, traffic markings, anti-collision facilities, barriers, sight guidance facilities, anti-glare facilities, bridge anti-throw nets, mileage indicators, 100-meter standards, highway boundary monuments, etc.
(A) traffic signs
Traffic signs use graphic symbols, colors, and text to convey specific information to traffic participants. They are used to manage traffic facilities, and are mainly used to prompt, induce, and instruct. It mainly includes the main signs such as warning signs, prohibition signs, direction signs, guide signs, tourist area signs, road construction safety signs, and auxiliary signs attached to the main signs. The support structure of the sign mainly includes column type (single column, double column), cantilever type (single cantilever, double cantilever), mast type and hanging type.
(II) Traffic markings
The main function of traffic markings is to regulate and guide traffic. It is composed of various lines, arrows, characters, elevation marks, protruding road signs, etc. marked on the road surface. The paint used to draw the road markings is divided into four types: solvent-based, hot-melt, two-component, and water-based. Spread glass beads on your face. Prominent road signs are classified into A and B categories according to whether they have retroreflective performance: those that have retroreflective performance are category A protruded road signs; those that do not have retroreflective performance are category B raised road signs.
(3) Anti-collision facilities
Anti-collision facilities mainly include guardrails and anti-collision cylinders. The main function of the guardrail is to prevent out-of-control vehicles from crossing the central divider or from dangerous sections of the roadside to rush out of the roadbed, so as not to cause secondary accidents. At the same time, it also has the effect of absorbing energy, reducing the degree of damage to the vehicles and people in the accident, and inducing vision. The form of the guardrail can be divided into flexible guardrails, semi-rigid guardrails and rigid guardrails according to different stiffnesses. According to the structure, it can be divided into cable guardrails, corrugated beam guardrails, concrete guardrails, beam-column steel guardrails, and combined guardrails. The guardrail board is divided into two kinds of double wave and three wave. The main function of the anti-collision cylinder is to absorb energy, reduce the degree of damage to the vehicles and people in the accident, and also induce the sight.
(Four) isolation barrier
The main function of the barrier is to isolate road land, and at the same time, separate people and animals that may affect traffic safety from the road to ensure the normal operation of the road. It mainly includes woven mesh, expanded metal mesh, welded mesh, barbed wire, partition wall and evergreen hedgerow.
(5) Guidance facilities
The sight-guiding facilities mainly include divergent and convergent signs, linear guidance signs, contour signs, etc. The main function is to allow drivers to understand the shape and direction of the road ahead by reflecting the lights at night, making them ready in advance. The structure of split and merge signs and linear guidance signs is the same as that of traffic signs. The outline signs mainly include attachments, columns and other forms. The retro-reflective materials used for contour marking mainly include reflectors and reflective films. Among them, reflectors are available in microprism and glass bead types.
(VI) Anti-glare facilities
The main function of the anti-glare facility is to avoid glare caused by the headlights and ensure driving safety at night. Anti-glare facilities are mainly divided into artificial anti-glare facilities and green anti-glare facilities. Artificial anti-glare facilities mainly include structural forms such as anti-glare plates and anti-glare nets.
(VII) Bridge anti-dropping net
Bridge anti-dropping nets are mainly set on the overpasses or the separate interchanges crossing the main line and the separate interchanges crossing the railway or other high-grade highways on the main line to prevent debris from falling on the road lanes under the bridge to ensure driving safety. It mainly includes steel mesh, welded mesh and other structural forms.
(8) Mileage mark (inscription), 100-meter mark (pile) and highway boundary monument
Milestones (stables), 100-meter (stakes) and highway boundary markers are mainly used to identify road mileage and highway land boundaries.
