Description

A water meter with data output interface

Technical field

The invention relates to a common water meter, in particular to a water meter with a data output interface.

Background technique

The statements in this section only provide background information related to the present disclosure, and these statements may constitute prior art. In the process of implementing the present invention, the inventor found that at least the following problems exist in the prior art.

At present, all ordinary water meters, as shown in Figure 1, have only a single metering function, and are directly installed on the pipeline for use after being sealed in accordance with the regulations of the metering law. If the existing ordinary water meters are to be retrofitted with additional intelligence, materialization, or remote copying, they cannot be retrofitted due to the metering regulations prohibiting unpacking of the inspected water meters; therefore, all current smart water meters Only ordinary water meters can be integrated with intelligent control components, remote control valves, power supply parts, etc., and integrated manufacturing verification seals. When any part of them is damaged or fails, the entire water meter must be replaced. Especially when the smart water meter reaches the replacement period stipulated by the metering law, the entire smart water meter has to be replaced. What should be replaced is the original ordinary water meter with metering function in the smart water meter. The cost of the smart water meter is only one-third of the cost of the smart water meter. First, it has caused a great waste of social resources, and it has also brought a lot of expenditure to water supply companies and users. Its huge economic investment has caused great obstacles to the intelligent promotion and application of the water meter industry that is vital to people's livelihood. . How to find breakthroughs in technological innovation, structural models, and compliance with measurement regulations has always been a pain point and difficulty for the industry.

For example, the name of the application number 201910538930.5 is "a remote water meter with a detachable remote controller". This invention is to install the remote controller on the water meter by a buckle, which is essentially a whole meter, just for Convenient maintenance. Although the remote controller and water meter can be made into a detachable form, although it can be used as a technical solution, the measurement law stipulates that after the entire meter is tested and sealed, the entire meter is not allowed to be disassembled and repaired. Therefore, the technology described in this invention The plan violated the mandatory provisions of the National Metrology Law, and it is impossible to enter the market as a product.

Another example is the application number 201910716375.0 named "a smart water meter". This invention is a technical solution that integrates the ultrasonic module, controller module, display module, etc. with the water meter. The disadvantage is that it is integrated manufacturing and the structural components of the water meter. Many, the system is complicated, and the reliability is poor. When one of the components is damaged or fails or the water meter replacement cycle is reached, the entire meter must be replaced, resulting in a great waste of resources and extremely high cost of replacing the meter.

Detailed ways

The present invention will be further explained below with reference to the accompanying drawings. The embodiments of the present invention are only used to illustrate the present invention and not to limit the present invention. Without departing from the technical ideas of the present invention, the invention is made based on ordinary technical knowledge and conventional means in the field. Various substitutions and changes should be included in the scope of the present invention.

As shown in Figure 2, a water meter with a data output interface includes a watch case 2, an impeller 3, and a gear transmission counting mechanism 4. The watch case 2 is sealed by a seal 13 to form an encapsulation area; the encapsulation area is provided with At least one non-mechanical contact sensing element 5 adapted to the gear transmission counting mechanism 4 is connected to the data output interface 7 fixedly arranged on the watch case 2 through the sensing element connecting line 6. The ordinary water meter 1 with the data output interface 7 is adopted, which can be selected and used according to the actual needs of the user. It can be used as an ordinary water meter alone, and at the same time, without violating the metering law and without opening the meter seal, it only needs to connect to an external smart device through the data output interface to realize the intelligent interconnection of the water meter. After connecting with the external intelligent device and the front valve of the remote control meter by plug-in connection, a new intelligent model water meter is combined. When a component of the external device plugged in is damaged, there is no need to use the name of the application number 201910716375.0 as "a smart water meter". Once a component is damaged, the seal 13 cannot be opened according to the provisions of the Metrology Law. For parts to be repaired, only the entire meter including multiple control modules can be replaced. In the water meter of the present invention, since the external components are only connected in a plug-in manner, there is no need to unpack the seal 13 of the water meter body in violation of the regulations of the measurement law, and only the damaged components of the external device need to be repaired or replaced, which greatly saves the operation and maintenance of the enterprise. cost.

When it comes to the water meter replacement cycle stipulated by the measurement law, without breaking the metering law, only the water meter with data output interface 7 needs to be replaced, and all other external intelligent IoT devices, IP addresses, and controls Valves, etc. can continue to be used, which greatly reduces the cost of meter replacement for water supply companies and saves a lot of social resources.

The ordinary water meter 1 can be a general dry water meter structure.

The data output interface 7 and the watch case 2 are manufactured as a whole, as shown in FIG. 3, so as to comply with the metering inspection regulations of the metering method. Alternatively, the data output interface 7 is a through hole for the sensing element connecting wire 6 to pass through.

The data output interface 7 is provided with a socket or a plug or a connecting wire terminal 7-1 inside. As shown in Fig. 3, the sensing element connecting wire 6 is connected to the connecting wire terminal 7-1. With the above structure, the data output interface can be equipped with various connectors such as USB, audio, type-c, etc., to connect with the Internet of Things, the Internet and various other communication systems.

As shown in Fig. 2, the water meter with a data output interface also includes a protective cover 14 detachably connected to the data output interface 7 for isolating the data output interface from the outside, thereby preventing dust or moisture. The protective cover 14 can be connected to the data output interface 7 in a detachable manner such as threaded connection or snap connection, and is connected to the data output interface 7 when leaving the factory. If it only needs to be used as an ordinary water meter, the protective cover 14 does not need to be removed to make it play a dust-proof and moisture-proof effect; if an external smart device is required, the protective cover 14 can be removed.

The non-mechanical contact sensing element 5 may be a magnetic sensing element.

Or, the non-mechanical contact sensing element 5 is a light sensing element, including a light projector 9 and a light receiver 10 that are adapted to the rotating part 8 of the gear transmission counting mechanism 4; when the rotating part 8 rotates, The light projected by the light projector 9 can pass through the rotating member 8 and be received by the light receiver 10.

At least one rotating part 8 of the gear transmission counting mechanism 4 is provided with at least one light-transmitting through hole 11, which is arranged between the light projector 9 and the light receiver 10. As shown in FIG. As shown in Figure 2, when the user uses water, the impeller 3 drives the gear transmission counting mechanism 4 to rotate. As shown in Fig. 4, the rotating part 8 is provided with a through hole 11. When the rotating part 8 rotates one circle, the light emitted by the light projector 9 passes through the through hole 11 and is received by the light receiver 10, thereby generating a pulse signal. The photoelectric sensor part is very simple, except that a light-transmitting through hole 11 is opened on the rotating part 8 of the gear transmission counting mechanism 4. Compared with the “meter”, because the non-contact sensing element is used, the original water meter structure is not changed, and the mechanical counting accuracy of the original water meter is not affected. And because the water meters are installed in the well room, the environment is humid, and the electronic components are more likely to be affected and damaged. The electronic component of the present application has a very simple structure, low cost, and a small number of components used, thereby reducing the probability of failure of the electronic component due to moisture, and has stronger environmental adaptability and higher reliability.

Optionally, the rotating component 8 is a gear plate of the gear transmission counting mechanism 4, as shown in FIG. 4. It only needs to be improved on the original gear plate of the original ordinary water meter 1 to meet the requirements, the structure is simpler, and the process requirements are lower. Alternatively, the rotating component 8 is a rotating disc sleeved on the gear transmission counting mechanism 4.

As shown in Figure 2, this application adds a light sensing element to the rotating part 8 of the gear transmission counting mechanism 4 in the ordinary water meter 1, and connects to the data output interface 7 through the sensing element connection line 6, and is packaged together at the factory. , Become a new kind of ordinary water meter that complies with the verification seal regulations of the Metrology Law. Since the light sensing element is not in contact with the gear wheel, when it is not connected to an external smart device, it can be used as a general water meter without affecting the accuracy of the digital wheel of the mechanical meter; as shown in Figure 5, when connected to an external smart device , It can be used as a smart water meter. When a component of the external device is damaged, it does not violate the regulations of the measurement law, and there is no need to open the seal13, and only the external device can be repaired; when the water reaches the end of its service life, or the internal components of the water meter are damaged, only the entire meter needs to be replaced. That is, the external smart device can still be plugged into the new watch to continue using it. Through the above method, under the premise of not violating the measurement law, the cost of water meter repair or replacement is greatly saved, and it has great commercial value.

The above-mentioned unspecified fixed connection may be a connection method such as riveting, welding, bolt connection, etc., and a movable connection may be a connection method such as hinged connection.
