Management end, to complete the meter reading of management end, in this way, can be broadcasted out water meter information by 4 remote transmitting water meter of voice mould group
Come, it is not necessary to by software tool connecting interface, user is allow directly to recognize very much the information in water meter, it is very convenient.
Embodiment two
Fig. 2 is the structural schematic diagram of remote transmitting water meter provided by Embodiment 2 of the present invention.As shown in Fig. 2, the present embodiment provides
A kind of remote transmitting water meter, comprising:
Controller 1, water metering mould group 2, teletransmission mould group 3 and the voice mould group 4 being connected with controller 1；
Wherein, water measures mould group 2, is used for metering user data of water meter, and data of water meter is sent to controller 1.
Specifically, water metering mould group 2 includes: with hydromining storage 21, water metering device 22.With hydromining storage 21 and use water
Meter 22 is connected, and water metering device 22 is also connected with controller 1, with hydromining storage 21 by the use in user's water meter
Water is acquired, and is counted by water metering device 22, obtains the water consumption of user's water meter statistics, and be sent to control
Device 1, and then stored by memory 6.It is understood that some controllers 1 are internally provided with micro memory, above-mentioned system
The water consumption of meter can also be stored directly in the memory inside controller 1.
Voice mould group 4 is sent for receiving voice broadcast request, and after receiving voice broadcast request to controller 1
Data of water meter request is broadcasted, to broadcast data of water meter.Specifically, voice mould group 4 includes: voice activated switch 41, voice control
Device 42 and speech player 43.Wherein, voice activated switch 41 can be opened for human body infrared-sensing type switch or dry-reed
It closes.Speech player 43 can be loudspeaker.
Specifically, human body infrared inductive switch is connected by infrared induction, any object of nature
Body, as long as temperature is higher than absolute zero (- 273 DEG C), always constantly sending out infra-red radiation, the temperature of object is higher, its institute
The infra-red radiation peak wavelength of transmitting is smaller, and the energy for issuing infra-red radiation is bigger.Therefore when people enters induction range, people
Body infrared-sensing type switchs the variation for detecting human body infrared spectrum, turn on automatically load, and people will hold without departing from induction range
Continued access is logical；After people leaves, automatic delay function load, in this way, user need not go to turn on the switch with hand, it can be so that circuit be led
It is logical, it is very convenient.
The main devices of human body infrared inductive switch are pyroelectric infrared sensor, and human body has certain body temperature, usually exists
36--37 degree, so the infrared ray of specific wavelength can be issued, the 9.5um infrared ray of human-body emitting is enhanced by Fresnel lenses
It gathers in infrared induction source, infrared induction source generallys use pyroelectric infrared sensor, and this element is to receive human body red
External radiation temperature will lose charge balance when changing, and discharge charge outward, and subsequent conditioning circuit can touch after detection processing
Send out switch motion.
Push button switch is a kind of electronic switch, operates pressuring direction to switch with the condition for meeting operating force when use
Switching function closure is connected, and is switched and is disconnected when cancelling pressure, and internal structure is to change by metal clips stress to realize
On-off.Key switch is specifically made of inserts, pedestal, elastic slice, button, cover board, and the push button switch in the present embodiment is
Waterproof key switch adds a strata imide membrane on elastic slice.
Dry-reed switch is by the magnetizable reed being overlapped at two panels endpoint, is sealed in a glass tube, two reeds
The distance of separation only about several microns are filled with the inert gas (such as neon, helium) of high-purity in glass tube, are not yet operating
When, two panels reed simultaneously makes two panels reed endpoint location nearby generate different polarity not in contact with, additional magnetic field, as a result two panels
The reed of opposed polarity will attract each other and be closed.Tongue tube is simpler than common mechanical construction of switch, small in size, speed is high, work
It is long to make the service life；And compared with electronic switch, it has the features such as anti-loading impact capacity is strong again, and functional reliability is very high.
Furthermore it is also possible to be speech controling switch, speech controling switch can be set according to the demand of user, such as
Open command can be " casting water meter information " etc. to be said against speech controling switch, to trigger the unlatching of speech controling switch.
There are many types of voice controller 42, by the way that voice controller 42 is arranged, can closely set to the information of casting
It is fixed, such as casting " March with 10 tons of water, adds up to use 100 tons of water ", it is, of course, also possible to broadcast table number, surplus water etc..
Controller 1 sends data of water meter for receiving data of water meter, and after receiving casting data of water meter request
It to voice mould group 4, is also used to for data of water meter being sent to teletransmission mould group 3, then management end is sent to by teletransmission mould group 3, so that pipe
Reason end counts on data of water meter.Wherein, there are many types of controller 1, for example, it may be single-chip microcontroller, specially
STM32L051C8T6 chip.
There are many types of teletransmission mould group 3, is divided into wired remote-transmission, such as M-Bus (symphonic mbus) wired remote
It passes；Wireless remote transmission, such as LoRa (Long Range Radio) wireless remote transmission, NB-IoT (Narrow Band Internet of
Things) wireless remote transmission.
The remote transmitting water meter that some embodiments provide, further includes alarm module 5, and alarm module 5 is connected with controller 1, is used
In in data of water meter reception failure alarm.In the present embodiment, by the way that alarm to be connect with controller 1, when controller 1 connects
