[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national patent for invention—water meter reading device. The patent was applied by Wuhu Vocational and Technical College and was authorized to issue on December 8, 2017.
Content Description
The invention relates to a water meter reading device.
Background of the invention
A water meter is a device that measures the amount of water used. Commonly used in tap water users, its degree is used to calculate the basis for water charges. Water meters usually measure total cubic feet (ft3) or cubic meters (m3).
At this stage, the remote meter reading system of the water meter transmits the data of the on-site meter and transmitter to the monitoring meter reading center through GPRS wireless communication. The data is collected and analyzed in the monitoring meter reading center to provide the basis for management and charging. . Pingsheng meter remote meter reading system is widely used in water conservancy, heat, gas, petroleum, industrial and mining enterprises and other industry users.
At present, it is impossible to accurately read the data of the water meter, and it is urgent to design a water meter reading device.
Summary of the Invention
The purpose of the present invention is to provide a water meter reading device that overcomes the problem that the data reading of the water meter cannot be accurately achieved in the prior art and achieves accurate reading of the water meter reading.
The drawing is a schematic view of a water meter reading apparatus according to a preferred embodiment of the present invention.
The water meter reading device includes a pulse emitting device, a pulse receiving device, a central controller and a mounting bracket. The mounting bracket is locked on the upper surface of the water meter, and the pulse emitting device and the pulse receiving device are fixed to the mounting bracket; the pulse emitting device faces the water meter. The pointer is located where the laser is sent. During the rotation of the pointer, when the laser irradiates the blank, the pulse receiving device cannot receive the laser. When the laser irradiates the pointer, the pulse receiving device can receive the laser and pass the laser. The controller counts the number of received lasers and calculates the flow rate.
The mounting bracket includes a mounting buckle and an adjusting mechanism. The mounting buckle is engaged with the upper surface of the water meter. The adjusting mechanism is disposed above the mounting buckle. The pulse emitting device and the pulse receiving device are disposed on the adjusting mechanism to perform the position. Adjustment. The adjusting mechanism includes: a base and a frame body; wherein the lower surface of the base is fixed to the mounting buckle, the pulse emitting device is fixed to the base, the frame body is disposed on the base, and the pulse receiving device is disposed on the frame body; on. The base has a ring structure, and the laser light emitted by the pulse emitting device is irradiated onto the pointer through the through hole at the center portion of the base. The frame body includes a vertical adjusting part and a horizontal adjusting part, and one end of the vertical adjusting part is fixed to the base, and the other end is connected to one end of the horizontal adjusting part. The other end of the horizontal adjusting part is connected with a pulse receiving device. The installation buckle comprises a first caliper, a second caliper and a third caliper, and the first caliper, the second caliper and the third caliper are fixed to the lower surface of the annular structure of the base. The central controller is wirelessly connected to the pulse receiving device, and the pulse receiving device is provided with a communication module.
Through the above technical solution, on the basis of not changing the structure of the original instrument, the measuring device is mounted on the surface of the surface of the transparent metering instrument (such as glass) on the front surface of the wheel meter, and is used to receive the laser pulses reflected from the tooth surface of the meter wheel. The laser beam emitted by the laser emitter irradiates the slot of the pointer. When the laser beam strikes the pointer, the laser receiver receives the reflected laser light and converts it to a high (or low) signal output. With the rotation of the pointer, the laser beam is then irradiated into the interdental groove of the pointer, and the laser receiver does not receive the reflected laser beam, so it is converted to a low (or high) signal output. As the pointer rotates, it receives a pulse signal.
