Problems solved by technology
[0003] After the completion of the project, if you want to increase the amount of collected data, you need to re-plug the signal line from the building, which will increase the construction volume and labor costs. Moreover, with the cable connection method, it is difficult to troubleshoot the line when the communication fails. When the communication cable When stretched, the line is susceptible to electromagnetic or other interference, resulting in data transmission errors and low communication success rate
In addition, the data acquisition host supports fewer sensor types, a single acquisition interface, and poor scalability

The invention discloses a wireless collection device. The wireless collection device comprises a signal collection interface, a central processing unit and a wireless transmission processing unit; thecentral processing unit is connected with the signal collection interface for collecting data of external equipment through the signal collection interface and analyzing the data to obtain correct data; and the correct data are transmitted to a LoRawan gateway through the wireless transmission processing unit. The invention further discloses a data collection method corresponding to the wirelesscollection device. The method comprises the steps of performing verification processing on the data by the signal collection interface to obtain the correct data; and then transmitting the correct data. The device disclosed by the invention can collect the correct data in a wireless manner, thereby improving the success rate of communication; and the device can identify the type of the external equipment, thereby improving the practicability of the device.
Description
technical field [0001] The invention relates to the field of signal transmission, in particular to a wireless collection device and a data collection method. Background technique [0002] Most of the traditional signal acquisition devices are connected by wires. There will be the following problems in the application of this signal acquisition device in the field of construction engineering: [0003] After the completion of the project, if you want to increase the amount of collected data, you need to re-plug the signal line from the building, which will increase the construction volume and labor costs. Moreover, with the cable connection method, it is difficult to troubleshoot the line when the communication fails. When the communication cable When stretched, the line is susceptible to electromagnetic or other interference, resulting in data transmission errors and a low communication success rate. Moreover, the data collection host supports fewer sensor types, has a singl...
