An embodiment of the utility model provides a photoelectric type water gauge, as shown in figure 1, include: 1 character wheel is provided with a light hole; the number of the infrared emitting diodes is 1; the number of the infrared receiving diodes is 1, and infrared light emitted by the infrared emitting diode can pass through the light-transmitting hole to be received by the infrared receiving diodes; the carry device is used for accumulating and counting after the number of the character wheel exceeds 9; and the microprocessor is connected with the infrared emitting diode, the infrared receiving diode and the carry device.
By adopting the technical scheme, through 1 character wheel, 1 infrared emitting diode and 1 infrared receiving diode, whether the infrared light emitted by the infrared emitting diode is received by the infrared receiving diode is determined through the light hole to determine the photoelectric signal, the photoelectric signal is obtained by the microprocessor and converted into data, and one more bit is carried out after the number exceeds 9 through the carry unit, so that the statistical display of the number of the water quantity of units such as a plurality of, ten, hundreds, thousands, ten thousands and the like can be realized only by using 1 character wheel. Compare in current with four five character wheels to realize checking meter, saved the quantity of character wheel, the cost is lower, and the accuracy is higher.
Preferably, the device further comprises an MBus interface, and the MBus interface is connected with the collector. Therefore, the data of the water meter can be acquired through the collector.
The M-Bus is designed specifically for the data Bus that carries information for consumption measurement instruments and counters. M-Bus has many aspects of application in building and industrial energy consumption data collection.
The information transmission capacity of the cable is specially limited to meet the application, and the cable has the characteristic of long-distance transmission by using a low-price cable. The reaction time of the M-Bus for each query is 0.1 to 0.5 seconds, which is completely sufficient for the task it is to accomplish. The M-Bus is not replaced by other data buses, but rather it is the safest and inexpensive to transmit counter readings. This has been confirmed in practical applications: the method can adapt to the fluctuation of the power grid voltage.
Furthermore, the device also comprises a power supply module which is used for supplying power to the carry unit and the microprocessor.
Preferably, the device further comprises a flow sensor, and the flow sensor is connected with the microprocessor.
In a preferred embodiment, the light-transmitting holes are fan-shaped through holes, and the number of the light-transmitting holes is 2.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
