What Are the Characteristics of the Photoelectric Meter Remote Reading System?
The photoelectric meter remote meter reading system is a bus system intelligent meter reading system product. It consists of three parts: meter unit, link unit, and the main control computer of the intelligent meter reading system management software. The meter unit includes a coded direct-reading meter, and the link unit includes: a concentrator, a repeater, and a collector. The system can simplify the user's operation to the greatest extent, and realize the true sense of staying at home and intelligent meter reading. So what are the characteristics of this system?
1. Direct reading: digitally encode the dial of the watch, and there is a decoder in the watch. When reading the meter, the system sends power to the meter, the decoder of the meter starts to work, and the flow value of the meter is sent out, realizing "direct reading".
2. There is no power supply in the watch: the electronic unit of the watch does not work at ordinary times, and the meter is instantly sent to the watch by the system or hand copy device to take the data away, and there will be no inaccurate measurement due to power supply or battery failure. The power consumption of the table is 0, the failure rate is greatly reduced, and the service life is longer.
3. Anti-jitter: No matter how severe the jitter is for the dial reading directly output, the decoder is static relative to the word wheel at the moment of decoding, which will not cause the output number of the watch to deviate from the dial reading of the watch.
4. Anti-backflow and strong magnetic interference: The traditional pulse counting method is an addition calculation, and the electronic reading can only be added, not subtracted, so the backflow will cause the meter reading to deviate from the system reading. Decoding direct reading is not a relationship of addition and subtraction, it is a direct reading of the digits of the word wheel. Reflow does not affect the decoding reading, and strong magnetic interference cannot affect the decoding reading.
5. The table has an address: The pulse meter does not have a table address, and needs to be distinguished by physical wiring, which is very difficult to construct and maintain. The direct reading table is identified by a unique address code and reading the data of the corresponding table according to the address code can ensure that the data is unique and correct.
6. Remote control: Control valves (switches) can be installed in water meters (electricity meters, gas meters, direct drinking water meters) according to actual needs. Through the remote control of the system, compulsory charging is realized to prevent malicious arrears.
7. Anti-static: The intelligent electronics unit is completely sealed in the counter (vacuum), completely isolated from the outside world, and will not be corroded by the external water, moisture, dust, etc.
8. Irrelevance: no collector, no need to set the initial value.
9. Real-time scanning: Real-time scanning and monitoring of various operating data states of water meters in the network and recording and archiving, detecting system abnormalities, transmitting fault information, and timely alarming, which is convenient for system maintenance. Quickly and accurately realize the online meter reading of residential water meters, and conveniently and quickly query the real-time data and historical data of each meter. The water company can save a lot of manpower and material resources, and greatly improve the meter reading rate and accuracy. Because the water consumption of each user can be inquired in real time, the dispatching department can know the load status of different regions of the entire network in time, which is convenient for grasping the load law and determining the best dispatching scheme. Moreover, the intelligent meter reading network system can make multiple engineering services share the bus, establish a close monitoring network, reduce customer investment, and reduce the waste of social resources.
10. Security:
(1) Authority setting: Operators are managed by operation authority, and a multi-level password confirmation mechanism is provided to ensure the safety and reliability of data.
(2) Data security backup and recovery: The system has data storage and protection functions, data compression and backup functions. It also has data analysis capabilities, such as generating the actual usage curve of each household based on historical data, and estimating the normal usage of the user. When the user's usage is abnormal, it will give an alarm, and can carry out corresponding control and management.
11. Easy to expand: bus topology, any point on the bus can be disconnected, adding nodes or direct reading meters in between, the system can add more residents at any time, which is convenient for centralized management.
12. Easy to maintain: The bus output of each direct-reading meter only needs to be connected, which reduces a lot of tedious wiring, system debugging tasks, and heavy labor intensity such as line and system maintenance in the later use process.
The above is the introduction of the performance characteristics of the photoelectric direct reading remote water meter reading system solution.
