Description of the Invention The utility model relates to the field of remote intelligent technology, in particular to a modular water meter collector.
BACKGROUND OF THE INVENTION With the continuous expansion of the city scale, large-caliber metering instruments play an extremely important role in water supply marketing. How to manage the large-caliber metering instruments is a problem that has always troubled the water supply enterprises. The timely and accurate measurement of large-caliber water meters has a direct bearing on the economic benefits of water-supplying enterprises. Accurate and accurate reading of water meter data is the basis for guaranteeing water fee recovery. At present, large-diameter pipelines are mainly underground or in other complicated situations. Traditional manual meter reading requires staff to read meters at large-diameter pipelines. The surrounding environment is generally harsh, time-consuming and labor-intensive, accuracy is not high, and wind and rain are encountered. The situation will delay reading the meter. Especially in the case of large-diameter water meters with abnormal conditions such as stopwatches and bad watches, it is difficult to find and handle them in a timely manner, which brings significant economic losses to the water supply enterprises.
Therefore, the present invention invents a modular water meter collector, which can help the company to improve the management level, reduce the workload of meter reading personnel, improve the efficiency of meter reading and the accuracy of meter reading, and can also effectively eliminate human factors from reading the meter. influences. The manpower and time saved can be used to strengthen water audits and reduce the rate of production and sales. At the same time, GPRS completes the data interaction within 1 minute, the static power consumption of the whole machine is controlled at 11uA, reducing the power consumption and extending the service life of the battery.
SUMMARY OF THE INVENTION The purpose of the present invention is to provide a modular water meter collector to solve the problems raised in the above background art.

Further, the communication interface module includes a communication interface 1 and a communication interface 2. The communication interface 1 is an RS232 communication port, the communication interface 2 is an RS485 communication port, and the pulse acquisition module includes a pulse acquisition interface 1 and a pulse acquisition interface 2, and the pulse acquisition interface 1 For the forward pulse acquisition interface, pulse acquisition interface 2 is the reverse pulse acquisition interface. When the water meter is a smart water meter, the GPRS remote water meter collector is connected to the smart water meter through the communication interface 1 or the communication interface 2. When the water meter is a pulse water meter, the GPRS remote water meter collector passes the pulse acquisition interface 1 or the pulse acquisition interface 2 and The corresponding water meters are connected. The water meter collector is powered by an external current power supply function module or an internal DC power supply module, or is powered by an external current power supply function module or an internal DC power supply module.
The utility model has the beneficial effects that the data collection and remote transmission of the large-diameter water meter/flowmeter can be effectively realized; the connection ends of the larger wire and the wire are designed, and the wires of more specifications can be adapted; and the difficulty of on-site meter reading is overcome. The problem has reduced the labor intensity of the staff and saved manpower and material resources; improved the accuracy and timeliness of meter reading data; unified data collation facilitated pipeline analysis and energy consumption management of the water company; reduced energy consumption and extended Battery life.
