The process of checking meter can be described as：
The uplink communication module, for receiving the order of checking meter that the host computer sends, the order that will check meter sends
Parsed to the main control module；Main control module is copied by the downlink communication module in the very first time to the unidirectional loop
Table network broadcast data acquisition, each intelligent electric meter obtains each current ammeter number according to the data acquisition command
According to and locally preserve；The downlink communication module, obtains each intelligent electric meter and is adopted according to the data in the second time
Collection order is obtained each current and gives the ammeter data of local preservation, and notifies the main control module by the ammeter data
The host computer is uploaded to by the uplink communication module after packing.
Specifically, the uplink communication module of concentrator receives the batch capture order that main website sends, and order is sent
To the main control module of concentrator, after concentrator main control module parses the batch capture order, ammeter data acquisition is generated, with
The mode of broadcast sends each ammeter communication module to ring by quantity optical fiber.
Wherein, Fig. 9 is seen, each ammeter that the unidirectional loop is checked meter in network has following characteristic：Ammeter communication module
Mode of operation is set to reception-transparent transmission, the reception-transparent transmission mode of operation specifically, the communication module of ammeter receives number
According to rear, the data is activation of reception processes (CPU) to the Programmable Logic Controller of communication module, while the transparent communication module that is sent to
Sending port, is sent to next equipment by sending port.
With reference to concentrator for broadcast data acquisition during unidirectional loop checks meter network, concentrator issues batch data
In acquisition to ring during (i.e. unidirectional loop is checked meter in network) first ammeter, the order is just pass-through to by first ammeter
Two ammeters, second ammeter is pass-through to the 3rd, and by that analogy, and due to concentrator and ammeter in ring, ammeter is with ammeter
Connected by plastic optical fiber, the transmission speed of plastic optical fiber is fast, therefore all ammeters are nearly simultaneously received batch capture life
Order.Therefore, the present invention can realize the quick reading of ammeter data.
Based on said system, after the communication module of ammeter receives broadcasting command, the mailing address according to each ammeter will
Order is sent to ammeter main control module, and electric main control module parsing data simultaneously return to ammeter data needed for acquisition, send to electricity
Table communication module；All ammeters carry out the action of resolve command and returned data, the life that will be completed one by one in the prior art simultaneously
Order is completed simultaneously.According to the present invention, ammeter quantity is more in the descending networking ring of concentrator, and acquisition speed lifting is more obvious.
In sum, the present invention rapidly can carry out batch capture to ammeter information, effectively lift communication bandwidth, meet
The demand of multi-user's power system.The present invention effectively overcomes various shortcoming of the prior art and has high industrial exploitation value
Value.
