The following is a brief description of the embodiments of the present invention by way of application examples, which are only used to illustrate the embodiments of the present invention and are not used to limit the scope of the present invention.
Application example
Fig. 7 is a schematic view of communication interaction of a sensor network according to an example of the application, and as shown in fig. 7, the sensor network includes: the server, the sensor device (device a, device B, device C, and device D in the figure) and the sensor device are mobile terminals with wireless communication transceiving functions, and the communication interaction process of the application example includes:
step 701, a server determines sensor equipment in a preset area and sends a reporting instruction for reporting equipment information to the sensor equipment through a mobile network; here, the sensor devices in the preset area may be detected and discovered through the mobile network.
Step 702, after receiving a reporting instruction, the sensor device sends device information to a server according to the reporting instruction; the device information may include basic information of the device, such as an IP address, a remaining power, a signal strength, a location, and the like.
And step 703, the server selects one of the sensor devices reporting the device information as a gateway according to the received device information.
Step 704, the server notifies the selected gateway to the equipment in the network through a notification message;
step 705, the device elected as the gateway (assuming that the gateway is device a) receives service data collected by other devices in the network;
step 706, the selected gateway receives the service data collected by other sensor devices in the network, and sends the received service data and the service data collected by the gateway to the server.
The application example sends the acquired service data to the server in a gateway election mode, so that the problems of data confusion and the like caused by uploading of the service data by a large amount of sensor equipment can be effectively avoided; the problems of large power consumption, long uploading time and the like caused by independent uploading of each sensor device can be avoided, and efficient transmission of service data is realized.
In an exemplary embodiment, if the service data received by the server from the gateway is longer than a first preset time, the server may determine whether the communication of the gateway is interrupted, and if the communication of the gateway is interrupted, trigger a process of reselecting the gateway.
When the network is initialized, all the sensor devices have the same power, but the distances from the sensor devices to the gateway are not always the same, so that the transmission rates of the sensor devices are different, and the energy consumption is also different. Assuming that the power consumption of the device a for uploading data to the platform through the mobile network is X1, the power consumption of the device B for uploading data to the platform through the mobile network is X2, and so on, the power consumption of all the devices for uploading data to the platform is X, that is, X is X1+ X2+ X3+ X4, so it can be seen that each sensor device uploads data information separately, and there will be a large power consumption.
According to the application example, when the gateway is selected, the gateway needs to be selected by the server according to the uploaded equipment information, and therefore the electricity consumption of the equipment is effectively balanced.
The application example can acquire the residual electric quantity information of the gateway, when the residual electric quantity of the gateway is smaller than the preset electric quantity, the processing of issuing the reporting instruction is executed again, and a new gateway is elected according to the newly received equipment information; in an exemplary example, the application example may further set a preset time duration as the time duration for reselecting the gateway, where the preset time duration may be determined by analysis performed by a person skilled in the art according to parameters of the sensor device, including the total power, the remaining power, and the like.
If the sensor equipment is elected as a gateway, receiving service data acquired by other sensor equipment; if the gateway is replaced, the new gateway replaces the original gateway to receive and send the service data, and when the sensor equipment does not operate as the gateway, the relevant information of the sensor equipment stored when the gateway receives the service data is deleted.
In the application example, the sensor equipment except the gateway can periodically collect the service data and send the service data to the gateway, and the sensor equipment can enter a dormant state at other time to save electric quantity; the gateway may periodically transmit the received traffic data to the server. According to the application example, the electric quantity consumption of the rest sensor equipment is reduced by electing the gateway and sending the service data of the rest sensor equipment through the gateway, and data transmission is carried out in a wireless mode, so that the network energy efficiency is improved, and the life cycle of the sensor equipment is prolonged.
Take device a as an example. The server uploads the data through all the sensor devices stored in the memory, and the data comprise: the method comprises the steps that devices such as residual power information, signal strength information, gateway selection times and position information are determined to be a gateway through set election rules. The server sends a notification that election device a is a gateway to device a, device B, device C, and device D. The device A receives the information that the device A is the gateway, and the original function is kept unchanged. After receiving the information that the gateway is the device A, the devices B, C and D close the wide area wireless communication network (wireless module) and keep the local transmission network open, thereby avoiding the situation that the sensor devices except the gateway independently upload service data to the server, causing confusion of uploaded data information and resource waste, and realizing low power consumption.
When the sensor equipment works, the equipment A, the equipment B, the equipment C and the equipment D acquire service data, the equipment B, the equipment C and the equipment D periodically communicate with the equipment A serving as a gateway through local transmission, acquired data information is sent to the gateway equipment A through a low-power-consumption network of a local transmission network, the gateway equipment A sorts the acquired service data and the received service data from the equipment B, the equipment C and the equipment D and sends the service data to a server through a mobile network, and the server receives all the service data uploaded by the gateway equipment A.
If the server receives the data uploaded by the gateway device A, the following steps occur: if the service data transmission is unsuccessful or the server responds to a data reception timeout, the server will make a detailed record of the occurrence of the condition.
If the server detects that the state of the gateway device A is communication interruption (fail), or the gateway device A cannot periodically upload service data, the server will reselect a new gateway; or more than one of the device B, the device C and the device D, when the service data is transmitted to the gateway device a, and when it is detected that the state of the gateway device a is communication interruption, the device B, the device C or the device D may start the wide area wireless communication network, send the state of the gateway device a to the server, the server detects the state of the gateway device a, when it is found that the state of the gateway device a is communication interruption, reselect a new gateway, and the elected new gateway device replaces the original gateway device a to periodically upload the service data. If the newly elected gateway device is the device B, the server will send the notification of the newly elected gateway to the device a, the device B, the device C, and the device D, in the same manner as the data receiving and sending of the original gateway device a. If the residual electric quantity is insufficient or the cost of the wireless network card is insufficient, the device A can still upload the acquired service data to the gateway through the local transmission network although the gateway cannot be selected. The application example aims at the problems of selection of the gateway and low circuit application efficiency, effectively improves the application efficiency of network resources and equipment electric quantity, and prolongs the operation period of the sensor network.
