Problems solved by technology
Temperature collectors generally include battery-powered GPRS wireless room temperature collectors and mains-powered GPRS wireless room temperature collectors. The disadvantage of using battery-powered methods is that it needs to use a large number of batteries and is limited by the battery life.
The disadvantage of using the mains power supply method is that it needs to occupy the sockets of citizens' homes, which is inconvenient to use
[0003] At present, there are also situations where the single live wire technology is used to supply power to electrical appliances, but when the back-end electrical appliances are turned off, it will cause malfunction of the electrical appliances when providing a large current for the electrical appliances.
Therefore, it cannot directly drive circuits that require a large instantaneous current, such as NBIOT modules or GPRS modules, etc.

The invention discloses a power supply device and method based on a single live wire power-taking module, which belongs to the technical field of electronic communication and includes a power supply, a step-by-step controllable constant current charging circuit, an energy storage element, an electronic switch, a controller, and a single live wire power-taking module. Module; the power supply is connected in series with the back-end electrical appliances, the single live wire power supply module is connected in series on the power circuit, the output terminal of the single live wire power supply module is connected to the input terminal of the step-by-step controllable constant current charging circuit, and the step-by-step controllable constant current charging The output end of the circuit is connected with the energy storage element, and the input end is connected with the controller; both the controller and the energy storage element are connected with the communication module through the electronic switch. The invention takes power by connecting single live wire power taking modules in series on the power supply circuit, adopts step-by-step controllable constant current circuits to limit the current of communication equipment terminals, and uses energy storage elements to supply power for communication modules, which can provide instantaneous larger circuits.
Description
technical field [0001] The invention relates to the technical field of electronic communication, in particular to a power supply device and method based on a single live wire power-taking module. Background technique [0002] In the field of heating, central heating is generally adopted. In order to grasp the heating effect in time, it is necessary to install temperature collectors in residents' homes. Temperature collectors generally include battery-powered GPRS wireless room temperature collectors and mains-powered GPRS wireless room temperature collectors. The disadvantage of using battery-powered methods is that it needs to use a large number of batteries and is limited by the battery life. The disadvantage of adopting the mains power supply method is that it needs to occupy the sockets in the citizens' homes, which is inconvenient to use. [0003] At present, there are also cases where the single live wire technology is used to supply power to electrical appliances, bu...
