Description
Technical field
The utility model relates to water meter technical fields, and in particular to a kind of low-power consumption metering remote transmitting water meter.
Background technique
Water meter is measured by the statistics to flow.Concrete mode: being the rotor by will be freely rotated, being mounted on water
In the water pipeline of table, indicators turn is driven, small-sized magnet is mounted on to one end of pointer, Hall magnetic sensor is mounted on pointer
Near rotational trajectory.Water flow is out-of-date when having, and when the pointer with magnetic regions is close to Hall magnetic sensor, Hall effect can be generated
One pulse signal, therefore ought constantly have that water flow is out-of-date, continuous pulse signal can be obtained, by uniting to pulse signal
Meter, realizes the metering of water.Currently, the common intellectual water meter metering of resident is divided to 10L and two kinds of 100L.The former is in order to improve essence
Degree accordingly increases the quantity of unit pulse, and water meter wakes up frequently, and power consumption increases obviously, this metering method is only without valve
Water meter uses；Water meter with valve can only use the metering method of 100L since the consumption of valve driving machine rotational energy is larger, and reduction be called out
Awake number reduces power consumption, but the reduction of unit pulse quantity, measuring accuracy is caused obviously to be not so good as the former.As shown in Figure 1, being existing
There are the water meter measurement mode of technology, including the first proximity Hall switch 1, pointer 2 and the second proximity Hall switch 3, water meter uses
Two Hall switch meterings, pointer per revolution can collect two pulses, and microcontroller wakes up twice, measuring accuracy
It is 0.5.Furthermore due to the limitation of cost, most of water meter lacks wireless communication ability, using manual metering, manage maintenance at
There is the problem of misreading pretermission often in this height.Even intellectual water meter, the basic function of remote meter reading is also only provided, water is lacked
The miscellaneous functions such as abnormal alarm, water leakage alarm, water meter abnormal alarm are measured, such as closestool leak, hand faucet are not fastened and do not alerted
Prompt, not only causes water resource waste, but also bring great inconvenience to users.
Summary of the invention
It is difficult to the low problem of the problem taken into account, degree of intelligence based on existing water meter power consumption, precision, the utility model provides
A kind of low-power consumption metering remote transmitting water meter to reduce the power consumption of water meter, raising measuring accuracy, and realizes the function of teletransmission and alarm
Energy.
To achieve the above object, the technical solution of the utility model are as follows:
Remote transmitting water meter, including table body are measured in a kind of low-power consumption, are provided with aquaporin in table body, are provided in the aquaporin
The rotor being freely rotated is provided with pointer on rotor, and one end of pointer is equipped with magnet, is additionally provided with pointer in the aquaporin
2, the first proximity Hall switch 1 and the first Hall sensor 4, the proximity Hall switch are connected with microprocessor, the Hall
Sensor connects converter, and the converter is connect with the microprocessor.
Further, the microprocessor is connected with the wireless communication module with terminal equipment in communication.
Preferably, the wireless communication module uses LORA module, and the LORA module is connect with terminal communication device.
The utility model has the following beneficial effects: being combined by the way that proximity Hall switch and Hall sensor are arranged in water meter
Metering method improve measuring accuracy while reducing power consumption, extend the service life of battery；Meanwhile passing through LoRa
Wireless communication module makes water meter have teletransmission meter reading, effectively reduces operation maintenance cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the metering method of the water meter of this prior art；
Fig. 2 is the structural schematic diagram of the metering method of the utility model specific embodiment.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.
As shown in Fig. 2, remote transmitting water meter, including table body are measured in a kind of low-power consumption, aquaporin is provided in table body, the water is logical
It is provided with the rotor being freely rotated in road, pointer 2 is provided on rotor, one end of pointer 2 is equipped with magnet, the aquaporin
It is inside additionally provided with a proximity Hall switch 1 and a Hall sensor 4, the proximity Hall switch 1 is connected with microprocessor,
The Hall sensor 4 connects converter, and the converter is connect with the microprocessor.Pointer per revolution, it is micro-
Controller wakes up once, can collect a pulse, reduces half power consumption, dynamic by converter when water to be acquired
State acquires Hall magnetic sensor 4 and detects magnetic field strength, and current pointer location is calculated in conversion, and then obtains water, and precision can
To reach 0.3, power consumption can be not only reduced, but also measuring accuracy can be improved.By the way that proximity Hall switch 1 is arranged in water meter
The metering method combined with Hall sensor 4 improves measuring accuracy while reducing power consumption, extends making for battery
Use the service life.
The microprocessor is connected with the wireless communication module with terminal equipment in communication.The wireless communication module of the present embodiment
Using the LORA module based on spread spectrum, the wireless communication of LoRa module and terminal device is realized, hand can be used in terminal device
The handheld devices such as machine, LoRa wireless communication has the characteristics of remote, highly sensitive, low-power consumption, is very suitable to water meter application, special
Be not long battery life, network capacity it is big, easily extension the advantages of, very convenient water meter networking management.
The transporting function of water meter may be implemented by LORA module for the present embodiment, meanwhile, pass through the statistical to water consumption
Analysis, carries out water data to go deep into excavation, provides personalized management of the use of water to different residents, provides additional miscellaneous function.
It is the preferred embodiment of the utility model it should be noted that described above, the utility model not office
It is limited to above embodiment, as long as its technical effect for reaching the utility model with identical means, it is practical new all should belong to this
