It is mainly composed of three parts of signaling basic meter, electric control circuit board and electric valve. As shown in fig. 1 and 2, the intelligent NB-loT remote water meter for the present production, sale and application of the applicant mainly comprises a base meter 1, an electric valve 14 arranged in a water through hole at one end of the base meter 1, a housing 2 arranged on the base meter 1, a top cover 3 fixedly arranged at one side of the top of the housing 2, and a flip cover 4 hinged at the other side of the top of the housing 2 and positioned right above the dial of the base meter, wherein a counting sensor 5 is embedded at one side close to the dial of the base meter in the housing 2, and an NB-loT remote control circuit board 6 and a power supply battery 7 are arranged at the same time.

The working principle of the intelligent remote water meter is as follows: the NB-loT remote transmission control circuit board 6 is used as an intermediate medium, data are transmitted between the management system and the intelligent water meter in a two-way mode, and the function of water supply management is achieved. The user pays for the water supply company by scanning the code, and the pre-purchased water amount is stored in the table. When water is used, the meter collects flow signals in real time and can deduct the flow signals from the pre-purchased water amount. When the residual water stored in the meter is less than a certain value, a sound alarm is given out to prompt a user to purchase water in time, and meanwhile, the electric valve driving motor 13 automatically closes the electric valve 14 gradually, so that the water supply flow is reduced gradually. When the residual water amount is zero, the valve is completely closed, and the user needs to go to a water supply management department again for payment or can automatically open the valve to continue water supply after the payment is carried out through mobile phone code scanning. The intelligent remote water meter brings great convenience to vast water consumers, simultaneously facilitates the charging work of a water supply management department, achieves the purpose of clear and useless consumption of both water supply parties, can prevent a small number of lawbreakers in the society from impersonating a meter reader to carry out illegal criminal activities to bring unstable events to the society, has a unique prepayment function, effectively solves the problem of difficult charging of the water supply department, and ensures the normal operation of the service of a water supply unit.

As shown in fig. 22, the utility model provides a subassembly modular intelligence NB-loT teletransmission water gauge when in actual use, the supporting statistics of reading application based on the information statistics in management system high in the clouds, based on the handheld mobile device of management end and based on the user side application of the handheld mobile device of user side of having developed. The base table 1 is installed and connected in series with a user water pipe, and the number and the digital account number of the intelligent water meter are bound with the information of the user. When a user uses a mobile phone, a tablet personal computer, a desktop computer and other devices, the user can scan the information code 305 on the top cover 3, or directly search and download a user terminal program in an application market, or search and pay attention to the enterprise public number in a mode of searching a micro-messaging applet and the like, so that operations such as online account registration, account information maintenance, account balance inquiry and recharging payment, water meter maintenance, account suspension or cancellation and the like are completed at a client. The relevant information of the client is automatically gathered to a management system of a water supply department through a mobile network, so that the relevant information can be counted in time, and the management personnel of the water supply enterprise can be guided to make a corresponding response strategy. In the normal water use process of a user, the dial plate on the base table 1 measures the water consumption normally, the counting sensing module 15 senses and detects the rotation condition of a water meter pointer in real time, detected water consumption information is transmitted to a management system of a water supply department in real time through the NB-loT remote transmission control circuit board 6 or is transmitted to the management system at regular time according to a preset period, and an information counting application program at the cloud end of the management system deducts the cost automatically and adjusts account balance.

When the account balance is zero, the valve is completely closed, and the user needs to pay again to a water management department or recharge and pay through an application program of the client; after recharging and paying, the information statistics application program at the cloud of the management system automatically and remotely sends a valve opening instruction to the NB-loT remote transmission control circuit board 6, the NB-loT remote transmission control circuit board 6 controls the electric valve driving motor 13 to rotate, so that the electric valve 14 is in an opening state again, and normal water supply is continued.

The meter reading personnel at the management end can check the water meter data transmission information of the water meter users in the responsible area by logging in the administrator account on the meter reading statistical application program of the handheld mobile equipment, and query conditions or statistical interfaces such as 'meter reading', 'meter reading failure', 'arrearage', and the like are set. The data information and the customer information corresponding to the water meter data automatically uploaded by the intelligent remote-transmission water meter are listed in a 'recorded meter' statistical interface, the customer information corresponding to the abnormal reported water meter data of the intelligent water meter is listed in an 'unrecorded meter' statistical interface, and the customer information corresponding to the balance of the user account number being zero is listed in an 'owed fee' statistical interface, so that managers can manually record the meter in time to update related data, check the working state of the intelligent remote-transmission water meter, guarantee the intelligent remote-transmission water meter with faults, manually submit a payment bill and manually remind customers of timely payment.

After the intelligent water meter is used for a certain period of time (such as 1 year), or when the electric quantity detection module of the intelligent remote water meter detects that the electric quantity of the power supply battery module 17 is possibly insufficient, a maintainer carries the power supply battery module 17 with the same specification to the intelligent water meter, and the old power supply battery module 17 is directly replaced by the new power supply battery module 17, so that the continuous supply of the electric energy of the control system in the intelligent water meter can be ensured, and the problem that the service life of the battery in the existing intelligent water meter is limited is solved. If this water gauge internals breaks down and need to overhaul or this water gauge needs to be changed, the maintainer hand-carries the electron device module of the same specification, direct intelligent water gauge department at user's department, use the instrument with top cap 2 from casing 2 perk and make the two separation, can overhaul or change NB-loT teletransmission control circuit board 6, remove the sealed glue of 19 top surfaces edges of clamp plate, can follow casing 2 with clamp plate 19 and propose, thereby can overhaul or change count sensing module 15 and motorised valve drive module 18, overhaul or change the back that finishes, accomplish once more equipment and sealed operation can.
