Description of the Invention The utility model relates to the technical field of water meters, in particular to a split water meter.
BACKGROUND OF THE INVENTION The same is true today in the booming water meter industry. The types of water meters are constantly increasing and come from different customers. As far as this situation is concerned, a water meter suitable for installation in a pipeline well is a king. Currently, smart water meters generally adopt an integrated design, in which the user swipes must be performed on the water meter. But now some installation environments, such as water meters installed in underground pipe wells, in this case if the use of common integrated IC card prepaid water meter, users must drill into the underground pipe wells, causing great inconvenience to the user operation . And if the user destroys the meter, the meter cannot be turned off automatically.
Summary of the Invention The utility model mainly solves the technical problems existing in the prior art, thereby providing a split-type water meter capable of automatically shutting down when the meter line is damaged, and at the same time, the user can view the metering number without entering the pipeline well.
The above technical problems of the present invention are mainly solved by the following technical solutions: The split type water meter of the present invention includes a water meter body and a remote monitoring box, and the remote monitoring box and the water meter body are connected by wires. The water meter body is installed in a pipeline well, and the remote monitoring box is installed outside the pipeline well. A main carrier device, a metering device and a solenoid valve are installed in the meter body, and a solenoid valve control device and a slave carrier are installed in the remote monitoring box. A control device, a control chip, and a display device, the electromagnetic valve is connected to a solenoid valve control device via a wire, and the measurement device is also connected to a display device through a main carrier, a wire, a slave carrier, a control chip, and the solenoid valve control device. Also connected to the control chip. 
The figure is a block diagram of the split type water meter of the utility model
Compared with the prior art, the utility model has the advantages that a remote monitoring box is set, a solenoid valve control device, a slave carrier, a control chip and a display device are installed in the remote monitoring box, and a main carrier is installed in the water meter body. , measuring devices and solenoid valves. The initial state of the electromagnetic valve in the water meter body is the closed state. After the remote monitoring box is powered on, the electromagnetic valve control device drives the electromagnetic valve to open. At the same time, the metering device calculates the amount of water when the user uses water, and the wire is used to provide power for the electromagnetic valve on the other hand. On the one hand for the transmission of water data. When the wire is broken, although the metered amount of water used by the metering device cannot be transmitted to the display device, the solenoid valve is de-energized and closed because the wire no longer supplies power to the solenoid valve. With this device, the water meter body and the remote monitoring box are separately installed. When the remote monitoring box is installed outside the pipe well, the user can view the water consumption outside the pipe well and automatically shut off the water meter body when the water meter is damaged. Users benefit from sabotage.
