Fig. 1 is a flowchart of a method for detecting environmental data according to an embodiment of the present application, as shown in fig. 1, the method includes the steps of:
step S102, receiving a query request for querying environment data of a target environment;
step S104, responding to the inquiry request, and transmitting the effective environment data with the generation time within the effective time to the user;
step S106, receiving report data transmitted by a plurality of sensors arranged in a target environment under the condition that effective environment data are not stored, wherein the report data comprise environment data detected by the plurality of sensors;
step S108, according to the preset weight corresponding to each sensor and the environmental data in the reported data, determining the environmental data of the target environment;
step S110, the determined environment parameters are sent.
Through the steps, the method comprises the steps of receiving report data transmitted by a plurality of sensors arranged in a target environment, wherein the report data comprises environment data detected by the plurality of sensors; according to the preset weight corresponding to each sensor and the environmental data in the reported data, the environmental data of the target environment is determined, so that the purpose of comprehensively determining the environmental data of the target environment by setting weights for a plurality of sensors is achieved, the accuracy and stability of environmental data detection are improved, the technical effect of the real condition of the target environment is more similar, and the technical problems that the temperature and humidity of the detection space of a plurality of sensors are difficult to comprehensively coordinate, and certain difference is caused between the temperature and humidity of the detection space of the sensors and the real condition in the related art are solved.
The plurality of sensors may be a temperature sensor, a humidity sensor, a PM2.5 sensor, a CO2 sensor, etc., and may be other sensors for detecting environmental data. The sensor may be a specific sensing device, or may be a device having a data acquisition function, for example, a home appliance equipped with a sensor, for example, an air conditioner having a temperature sensor, an air purifier having a PM2.5 sensor, or the like.
The target environment may be a space having a certain degree of closure, such as a home, a room, etc. The environmental data are collected so as to better change the environmental data, the environmental data are easy to change in a smaller range, and the environmental data of a space with a certain sealing degree only have collection significance. However, in other cases, the collected environmental data is simply collected environmental data, and is not intended to change the environmental data of the target environment, and the target environment may be outdoor, open, and not have a space with a closed degree.
The target environment data is typically a query request of a client-based application, and is responded to by the query request. Specifically, fig. 2 is a flowchart of the complete steps of the method for detecting environmental data according to embodiment 1 of the present application, as shown in fig. 2, step S106, where, in the case where valid environmental data is not stored, receiving reported data transmitted by a plurality of sensors disposed in a target environment includes: step S1062, transmitting a query command to the plurality of sensors in response to the query request; step S1064, receiving the report data reported by the plurality of sensors in response to the query command, storing the report data, and recording the report time.
However, in this embodiment, the reported data of the sensor may be received in real time and cached, so that a user can respond quickly when requesting. That is, after the step S102 and the step S110, the environment data is directly transmitted to the client by receiving a query request for querying the environment data of the target environment.
That is, step S110 includes, after determining the environmental data of the target environment according to the plurality of parameter items of the environmental data of the target environment, step S1122 of recording the generation time of the environmental data; step S1124, when the generation time of the environmental data and the generation time of the last environmental data are less than the effective time, replacing the newly generated environmental data with the last environmental data as the environmental data of the effective time; in step S1126, an environment data curve of the target environment with the valid time as the time granularity is generated according to the environment data of the valid times. Thereby ensuring validity of the environmental data within the validity time. The effective time may be 1 minute.
And then, after receiving the inquiry request, responding and sending the environment data in the effective time to the client. However, if the environment data does not exist in the valid time after the request is received, the environment data needs to be determined according to the flow of the step S102 to the step S110, and the query request needs to be responded.
Step S108, according to preset weights corresponding to the plurality of sensors and environment data in the reported data, determining the environment data of the target environment comprises: step S1082, selecting the reported data of a plurality of sensors in the effective time as target data; in step S1084, environmental data of the target environment is determined according to the target data of the plurality of sensors and the corresponding preset weights.
The preset weight includes: the first preset weight and the second preset weight; the first preset weight is a weight of accuracy of the acquisition parameter item of the sensor, for example, as shown in table 2, and the evaluation coefficient of the device function is the first preset weight; the second preset weight is a weight of a parameter item collected by the sensor, for example, as shown in table 3, and the evaluation coefficient of the equipment class is the second preset weight.
Optionally, step S1084 includes determining, according to the target data of the plurality of sensors and the corresponding preset weights, environment data of the target environment: step S1086, calculating a value of one parameter item of the environment data of the target environment by:
wherein Z is the value of the parameter item of the environmental data of the target environment, Z i Representing parameter items in target data of the ith sensor, D i A first preset weight representing a parameter item of the ith sensor, F i A second preset weight representing a parameter item of the ith sensor, i being a natural number greater than between 1 and n; in step S1088, the environmental data of the target environment is determined according to the values of the plurality of parameter items of the environmental data of the target environment.
When the value of the parameter item of the target data of the sensor is determined, the determination is carried out according to the number of the parameter items of the target data in the effective time, and when the number of the parameter items of the target data is multiple, the average value of the multiple parameter items is taken as the value of the parameter item of the target data. In the case where the parameter item of the target data is one, the value of the parameter item is regarded as the value of the parameter item in the valid time.
Optionally, after determining the environmental data of the target environment according to the plurality of parameter items of the environmental data of the target environment, the method further includes: recording the generation time of the environment data; when the generation time of the environmental data and the generation time of the last environmental data are smaller than the effective time, the newly generated environmental data are replaced with the last environmental data to serve as the environmental data of the effective time; and generating an environment data curve of the target environment with the effective time as time granularity according to the environment data of the effective times. So that the application measures the history curve of the space data for subsequent description.
