The intelligent meter reading main control board in the intelligent meter reading terminal in the meter reading system needs to be researched and developed by self, the intelligent terminal can be realized by selecting a plurality of single-chip microcomputers and the like, and the RS485 communication cable is laid, so that the data of each electric meter in the charging station can be copied and transmitted to the intelligent meter reading terminal.
In this embodiment, the operation flow of the intelligent meter reading real-time reconciliation device of the charging pile is shown in fig. 2.
And the meter reading system continuously reads the data of the electric meters, records and stores the electric quantity data of each electric meter every whole half hour, and reports the state data of the electric meters, the communication state of the intelligent meter reading terminal and the electric meters and the running state of the electric meters to a cloud server platform in the reconciliation system for the analysis and the processing of the cloud server platform.
The real-time account checking device installation of intelligent meter reading of filling electric pile of this embodiment is simple, and intelligent meter reading terminal mainboard can get into the mode of setting through dial switch, reads automatically and sets up and preserve the ammeter address, withdraws from the mode of setting, and the terminal of checking meter just begins to snatch ammeter running state and data and uploads in real time and give the server. The intelligent meter reading terminal is firstly connected with the cloud server platform after entering a normal working mode, then sends a login message to the cloud server platform after being encrypted, the cloud server platform analyzes according to a protocol after receiving the login information, and receives and processes the message sent by the equipment if the terminal equipment is authorized after analyzing; if not, the server will not receive the message of the device, and disconnect the network connection of the terminal. In a cloud server platform, authorized terminal equipment can send heartbeat messages and state information every 30 seconds, a server in the cloud server platform can judge the state of the intelligent meter reading terminal equipment and the electric meter running state associated with the intelligent meter reading terminal equipment in real time according to the messages, so that the running condition of a charging pile site can be mastered, an operator accesses a cloud server through a browser to authorize a newly added meter reading terminal, when the newly added intelligent meter reading terminal is added, the corresponding operator, the site corresponding to the operator and the rate of the site are set and bound together, subsequent processing is facilitated, after the intelligent meter reading terminal is logged in the cloud server platform, the intelligent meter reading terminal can actively upload an electric meter address and an electric meter number connected with the intelligent meter reading terminal, the cloud server automatically associates the corresponding electric meter with the meter reading terminal according to the data, and at the moment, the electric meter reading terminal equipment can automatically read the electric meter according to the data, The ammeter, operator, charging station just are correlated with together, because there may exist a website and have a plurality of ammeters, consequently need the operator to correlate every stake and the ammeter that corresponds of website, guaranteed that whole system can be very accurate carry out data statistics contrast, let whole system more nimble changeable simultaneously, in order to make things convenient for user operation, can directly upload EXCEL form according to the regulation form, can supply the customer to be quick with stake and ammeter correlation.
After the configuration, the cloud server platform can issue an instruction for reading data of a certain electric meter, so that the total electricity consumption of all charging piles under the electric meter can be counted, the electricity consumption in each time period in 48 time periods is accurate, the rate of the site is also bound with the intelligent meter reading terminal, according to the rate of each time period and the electricity data of each time period, after the statistics is summarized, the electricity consumption of the whole charging station can be known, an electric vehicle charging user scans the code through a WeChat public number or APP to start charging, when the charging is completed, the charging pile can upload a charging order to the cloud server platform, the electricity and the cost in each time period are time periods, and therefore the cloud server can calculate the electricity in each time period of the whole charging site through the data. For example, under a meter reading terminal, an electric meter 1 and associated charging piles comprise a charging pile 1, a charging pile 2, a charging pile 3, a charging pile N, and in the same time period, through calculation of aggregate by a server, it is found that the electric quantity used by the electric meter 1 is more than the total electric quantity of the charging piles 1 to N, because the charging piles are lost when not being charged, the charging pile system needs external power supply to maintain the operation of the charging pile, and meanwhile, a power module also loses when charging an automobile, which is called as power loss, so that the electric quantity counted by the electric meter is more than the electric quantity of a charging order of the charging piles, which is normal, if the electric loss value exceeds a threshold value (which can be set by an operator), the charging station is abnormal, the cloud server sends a short message or a micro-message to remind the operator of timely searching for reasons, because the electric quantity counted by the whole system is the electric quantity data every half hour, the abnormal conditions can be basically found every half an hour, and the time period of abnormal electricity use can be accurately calculated, so that operators can find and process the abnormal electricity use in time, and more losses are avoided.
