Background

An NB-IoT narrowband Internet of things water meter is an electronic remote transmission water meter which is convenient for a water management department to realize remote meter reading and monitoring. The meter is based on a signaling water meter, realizes remote meter reading and monitoring through a narrowband Internet of things technology (NB-IoT), and provides data analysis service by being matched with upper computer software. In order to save electricity, the water meter is normally in a low-power consumption working mode, the circuit is set to process and upload data in a fixed time period every day, a valve of the water meter is automatically closed after a user owes fees, and after the user pays fees and recharges, the valve cannot be opened in time because the recharging time is not necessarily in the data uploading time period, so that the user is required to manually activate the circuit.

The circuit activation modes of the existing prepayment remote water meter in the market are mainly three, and the circuit activation modes mainly have the following defects in the using process:

1. push-button switch

The switch part is arranged in the control box, the button part is exposed out of the control box, and the circuit is activated through the button. The disadvantage of this approach is that the push-button switch has poor sealing properties; the adhesive film above the button is easily damaged after a period of use.

2. Split switch

The inside tongue tube that is equipped with of control box sends the user with the magnet steel as the accessory to inform the tongue tube position, be close to the tongue tube with the magnet steel when needing activation circuit, through activation tongue tube activation circuit. The disadvantage of this method is that the magnetic steel is separated from the water meter and is easy to lose; the reed switch is close to the outer side of the control box and is easy to be attacked by a magnetic field.

3. External slide switch

The control box is internally provided with a reed switch or a Hall element, a sliding switch is arranged above or on the side edge of the control box, magnetic steel is attached to the sliding switch, and a circuit is activated through the sliding switch. The disadvantage of this method is that the slide switch is arranged on the surface of the control box, and the appearance is poor; the switch has obvious activation position and is easy to be attacked by magnetic field.
