Metering device, metering method and computer readable storage medium

[0002] In the field of air conditioning, the billing data of the air conditioning system will be sent to the gateway for summary and storage. When the gateway system crash...

First, at least two gateways are adopted in a distributed layout mode, decentralized, and the storage module is independent and offline for the data storage operation of the metering piece, so that the metering device can run more stably and simpler construction layout.

First, the distributed layout mode can reduce the construction and deployment of the system, and the access between any two gateways in at least two gateways can be carried out through the local area network, and the local area network between buildings has been quite common in the current situation , no additional construction is required. Each gateway only needs to be connected with its corresponding measuring piece, and then output via Ethernet or wireless network.

In this embodiment, as shown in Figure 5, after the user acquires the first metering data received by the master gateway and the second metering data stored by the master gateway, the data between any two gateways can be disconnected immediately connection, or disconnect the data connection between any two gateways after a preset time. By disconnecting the data connection between any two gateways after the data acquisition is completed, the data transmission between the gateways is realized only when the user obtains the metering data, which avoids unnecessary data transmission between the gateways and causes the gateway to store Too much data will cause the gateway to crash and affect the stability of the metering device.

In this embodiment, when the user controls the metering piece 100 through the input device 300, the user inputs the metering piece 100 control instruction through the third data interface 214, the fourth data interface 216, and the second data interface 206 successively. To the control module 218 , the control module 218 transmits the control instruction of the metering unit 100 to the metering unit 100 through the first data interface 202 , so that the metering unit 100 executes the control command of the metering unit 100 input by the user. By setting the control module 218 to transmit the user's control command to the metering piece 100, the data transmission path between the metering piece 100 and the storage module 208 is separated from the data transmission path between the input device 300 and the metering piece 100, so as to realize multi-path Data transmission, improve the speed of data transmission.

[0051] The metering device provided according to the embodiment of the present invention includes at least two groups of metering pieces 100 and at least two gateways 200, wherein each group of metering pieces 100 has a set of metering data, and each gateway 200 can acquire and store a set of metering data. metering data. By arranging multiple gateways 200, the measurement data on each group of measurement pieces 100 is stored by different gateways 200. On the one hand, since the measurement data are stored separately in different gateways 200, it is avoided that one gateway 200 stores too much data. It is easy to cause the problem that the gateway 200 crashes. On the other hand, since the metering data of multiple sets of metering parts 100 are stored on different gateways 200, when a gateway 200 fails, the user can use the metering data stored in other gateways 200 that have not failed. Data is used for billing work, avoiding the problem that a gateway 200 crash will cause all data loss, resulting in the user being unable to perform billing work on the air-conditioning system. Based on this, the present invention completely solves the situation in the background art that when the gateway 200 system crashes or the gateway 200 stops working unexpectedly, the billing work for the air...
