Embodiment 1

[0016] refer to figure 2 , shows a flow chart of steps of a method for energy saving of a clicker according to Embodiment 1 of the present invention.

[0017] The energy-saving method of the clicker in this embodiment includes the following steps:

[0018] Step S102: Detection step: the clicker in the receiving state detects whether an instruction is received from the receiver in the first time window.

[0019] Wherein, the first time window is a set detection period in each reception detection cycle, and the first time window is used to detect whether an instruction is received from the receiver. The clicker only performs detection in one set detection period in each reception detection cycle, instead of all detection periods in the entire reception detection cycle, which can effectively save electric energy and improve the overall energy saving effect of the clicker.

[0020] Clickers generally have four states, namely: sleep state, screen on state, sending key value stat...

Embodiment 2

[0032] refer to image 3 , shows a flow chart of steps of a method for energy saving of a clicker according to Embodiment 2 of the present invention.

[0033] The energy-saving method of the clicker in this embodiment includes the following steps:

[0034] Step S202: Establish a communication link between the clicker, the receiver and the PC host.

[0035] Wherein, the receiver can be connected to the PC host through the USB interface of the PC host, and the connection between the receiver and the clicker is established through a wireless communication link, such as through 2.4G wireless technology. The working frequency band of 2.4G wireless technology is between 2.400GHz and 2.4835GHz, which can not only perform fast data transmission, but also save energy and electricity.

[0036] Step S204: Establish a mapping relationship between clickers and students.

[0037] Because the students in each class may be different, therefore, before each class, a mapping relationship nee...

Embodiment 3

[0054] refer to Figure 4 , shows a structural block diagram of a question clicker according to Embodiment 3 of the present invention.

[0055] The clicker in this embodiment includes: a detection module 302, used for the clicker in the receiving state to detect whether an instruction is received from the receiver in the first time window, wherein the first time window is the setting in each receiving detection cycle Detection period; judging module 304, used to determine whether the instruction includes information indicating to start the second time window if the instruction is received; the first execution module 306, used to determine if the judging result of the judging module 304 is included, then Start the second time window, receive data from the receiver and display it within the time period of the second time window; the second execution module 308 is used to return to the detection module 302 to continue execution if the judgment result of the judging module 304 is ...

Abstract

The embodiment of the invention provides an energy-saving method of an answering device and the answering device, the energy-saving method of the answering device comprises a detection step of detecting whether the answering device in a receiving state receives an instruction from a receiver or not in a first time window, wherein the first time window is a set detection time period in each receiving detection period; a judgment step: if an instruction is received, judging whether the instruction contains information for indicating starting of a second time window or not; in the first execution step, if yes, starting the second time window, and receiving dat from the receiver within the time period of the second time window and displayed; a second execution step: if not, returning to the detection step to continue to execute the detection step, wherein the duration of the first time window is smaller than that of the second time window. According to the embodiment of the invention, the power consumption of the answering device can be saved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of network teaching, and in particular to a method for saving energy for a clicker and the clicker. Background technique [0002] In the online classroom, in order to facilitate students to answer classroom questions and enrich the classroom atmosphere, a clicker is introduced. A clicker is a terminal device used for interaction between students and teachers, mainly composed of a display screen and answer buttons. The clicker utilizes a receiver connected to the PC host to interact with the PC host. [0003] An interactive process between a clicker and a PC host is as follows: figure 1 As shown, in the uplink data transmission process, after the student presses the button of the clicker, the clicker sends the key value to the receiver, and the receiver sends the key value to the PC host after receiving the button message; in the downlink data transmission In the process, the PC h...
