Thus, after the gateway device 12 collects the data, the gateway device 12 may transmit the collected data to the server 13 so that the server 13 stores or displays the data.
Second embodiment
Referring to fig. 2, a second embodiment of the present invention provides a data communication method, which is applied to a gateway device in a data communication system. The data communication method comprises the following steps: step S100 and step S200.
Step S100: and when the M terminal devices are in a communication state capable of carrying out data transmission with the gateway device and the N terminal devices are in a low-power consumption state incapable of carrying out data transmission with the gateway device, acquiring first metering data acquired by each terminal device transmitted by each terminal device in the M terminal devices in the low-power consumption state.
When data acquisition is performed on the X terminal devices, the gateway device needs to be networked with the X terminal devices. Specifically, the operator may input device information of X terminal devices into the gateway device. The input mode may be that the device information of the X terminal devices is input to the gateway device through the server, or the input mode may be that the operator directly inputs the device information of the X terminal devices to the gateway device at the installation site of the gateway device. In the input device information of the X terminal devices, the device information of each of the X terminal devices includes: device ID and channel data. In the input process, the operator inputs the device information of each terminal device according to a certain sequence, the gateway device divides the data collected by the X terminal devices into at least two successive batches according to the sequence of obtaining the device information, and then the sequence of the batches is used as the preset sampling sequence. After all the device information of the X terminal devices is sequentially input, the gateway device stores all the device information, so as to configure the X terminal devices. And then the gateway device can establish connection with each terminal device according to the stored information and synchronize the time of each terminal device after connection, so that the time timing of each terminal device can be synchronized with the time timing of the gateway device.
In this embodiment, each of the X terminal devices has two operating states. One working state is a low power consumption state, when the terminal device is in the low power consumption state, the terminal device cannot perform data interaction with the gateway device due to low power consumption, but the terminal device can acquire metering data of a corresponding user when the terminal device is in the low power consumption state. The other working state is a communication state, when the terminal equipment is in the communication state, the power consumption of the state can ensure that the terminal equipment and the gateway equipment perform data interaction, but the terminal equipment can acquire the metering data of the corresponding user when in the low power consumption state.
The switching of the working states of the X terminal devices is corresponding to the batch corresponding to the preset sampling sequence, namely the working states of the terminal devices in at least two batches and only one batch are kept in a communication state, the other batches except the batch are all guaranteed to be in a low power consumption state, and the working states of the terminal devices in each batch are kept synchronous in real time.
In this embodiment, each terminal device of each batch is preset with a preset duration, and the preset duration is a duration in a communication state. In addition, each terminal device of each batch is also preset with a sleep time length, and the sleep time length is the time length in a low power consumption state. Since the time timings of the terminal devices in each batch are kept synchronous with the gateway device, taking the start of the communication state as an example, if the time duration of the time timings of the terminal devices in each batch is equal to the preset time duration, the terminal devices in each batch are synchronously switched from the communication state to the low power consumption state. And then, when the time length of the time timing of each batch of terminal equipment is equal to the dormancy time length, synchronously switching each batch of terminal equipment from the low power consumption state to the communication state, thereby forming a cycle.
And after networking, the gateway equipment can correspondingly sample in batches according to the configured preset sampling sequence and switch according to the working state of each batch of terminal equipment, and then the gateway equipment acquires data of X pieces of terminal equipment in batches.
In two continuous batches of at least two sampling batches, one batch sampled firstly is M terminal devices, one batch sampled later is N terminal devices, and M and N are integers which are more than or equal to 1.
When the sampling of the current batch of terminal equipment is finished and M terminal equipment of the current batch is sampled. It can be understood that, in this state, M terminal devices are in a communication state capable of performing data transmission with the gateway device, and all terminal devices, except for the M terminal devices, of the X terminal devices, including the N terminal devices, are in a low power consumption state incapable of performing data transmission with the gateway device. Further, in the process, based on the transmission of each of the M terminal devices, the gateway device may first determine whether to obtain first metering data, which is acquired when each of the M terminal devices transmits, in the low power consumption state.
And when the judgment result is yes, the characterization gateway device already obtains the first metering data corresponding to each terminal device. And the gateway device can continuously send a plurality of successful feedback information to each terminal device in the M terminal devices. Therefore, each terminal device in the M terminal devices can acquire the success of data transmission when acquiring any feedback information, and further data transmission is not needed.
And if not, characterizing that the gateway equipment does not obtain the first metering data corresponding to each terminal equipment. And then the gateway equipment adds 1 to the total number of transmission failures of each terminal equipment in the M terminal equipment, and judges whether the total number of transmission failures meets the threshold number of times. When the number of times of the threshold is judged to be met, it is indicated that each terminal device in the M terminal devices is in a fault state, and the gateway device controls each terminal device in the M terminal devices to perform fault self-detection, so that each terminal device in the M terminal devices performs device check with the gateway device. When error information is found and corrected in the process of checking the device information, it can be considered that each of the M terminal devices has a fault removed, and each of the M terminal devices is awakened. On the contrary, when no error information is found in the process of checking the equipment information, the fault can be considered as that the fault cannot be eliminated, and then the gateway equipment generates alarm information to the server to inform an operator of overhauling. And when the judgment result shows that the number of times does not meet the threshold value, controlling each terminal device in the M terminal devices to retransmit the first metering data of each terminal device within a preset time length. Further, when each of the M terminal devices is not faulty, the gateway device may obtain the first metering data of each of the M terminal devices.
It should be noted that, each time the first metering data is not received, the gateway device may execute the unreceived determination process. When the synchronous timing duration of each of the M terminal devices and the gateway device reaches the preset duration, no matter whether the gateway device receives the first metering data, each of the M terminal devices is switched from the communication state to the low power consumption state, and the gateway device correspondingly obtains the data of the next batch, i.e., N terminal devices, according to the preset sampling sequence.
As another implementation manner of this embodiment, after each terminal device in the M terminal devices sends the corresponding first metering data, each terminal device may determine whether to obtain any one of the plurality of successful feedback information fed back by the gateway device. And when the judgment result is yes, each terminal device acquires that the transmission is successful. And then each terminal device in the M terminal devices switches the state after the preset time length. And if the judgment result is negative, that is, each terminal device in the M terminal devices does not obtain any successful feedback information after waiting for a certain time, each terminal device knows that the transmission fails. And each of the M terminal devices adds 1 to the total number of failures, and judges whether the total number of failures meets the threshold number set by each of the M terminal devices. And if so, interacting each terminal device in the M terminal devices with the gateway device to execute fault self-detection. And if not, each terminal device in the M terminal devices retransmits the corresponding first metering data to the gateway device. And if the transmission of each terminal device in the M terminal devices is failed repeatedly all the time and the total failure times of each terminal device in the M terminal devices do not meet the threshold times, each terminal device in the M terminal devices is directly switched to the low-power-consumption state when the timing duration reaches the preset duration.
Step S200: and in the process that the M terminal devices are in the low power consumption state and the N terminal devices are in the communication state, second metering data collected by each terminal device in the low power consumption state and transmitted by each terminal device in the N terminal devices are obtained.
When the acquisition of the last batch of M terminal devices is finished, all the other terminal devices including the M terminal devices are in the corresponding low power consumption states except the N terminal devices in the X terminal devices, and further, the N terminal devices in the current batch are correspondingly switched from the low power consumption states and are in the communication states.
It can be understood that the gateway device obtains the second metering data corresponding to each of the N terminal devices in the same manner as in step S100, and a detailed description thereof is omitted here.
In addition, after the data acquisition is carried out on the N terminal devices, the gateway device can judge whether the sampling of the X terminal devices is completed according to a preset sampling sequence. If not, continuing to sample the next one, and if so, sampling each terminal device of the initial batch in the preset sampling sequence according to the preset sampling sequence, thereby forming a cycle.
