Embodiment Construction

[0028] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0029] The low power consumption implementation method of the wireless transmission manual pulse generator of the present invention, such as figure 1 and figure 2 shown, including the following steps,

[0030] ① WMPG 100 communicates wirelessly with WMPG-PEER 200 located on the side of the CNC equipment in the ISM frequency band;

[0031] ②The WMPG-PEER 200 is powered by the numerical control equipment and periodically sends broadcast beacons. If the user turns off the numerical control equipment, the WMPG-PEER200 will no longer continue to send broadcast beacons due to power failure;

[0032] ③ The WMPG 100 receives the broadcast beacon, if the broadcast beacon is not received within the set time, the WMPG 100 turns off its rotary encoder, enters the standby state, and RSSI Detect the field strength of the broadcast beacon, and each continuous...

Abstract

The invention relates to a low power implementation method and a device for a wireless transmission pulse generator (WMPG) which operates in the ISM frequency range in the industrial computer control field. The lower power implementation method includes the procedures that the WMPG adopts the combination of the dynamic frequency point selection and the direct sequence spread spectrum (DSSS) for the communication with high reliability; when the state of <user mode > is not detected, the power supply of the input part is closed by the WMPG which receives the periodic wireless broadcasting beacon from the numerical control equipment on the opposite end through low speed mode; when the state of <user mode> is detected, the power supply of the input part is recovered rapidly by the WMPG which processes incremental encoding towards the user input and transmits the encoded user input; if the WMPG is time-out and receives no periodic broadcasting beacon, the WMPG closes the power supply of the input part and starts the lower power field density detection mode. The low power implementation method and the device have the advantages that the lower power implementation is adopted so that the battery is not needed to be replaced frequently or the chargeable battery is not needed to be charged frequently; the implementation method and the device can detect and switch the user mode automatically; the transmission speed is high and reliable.

Description

technical field [0001] The invention relates to a computer program control system, in particular to a method and device for realizing low power consumption of a manual pulse generator device in a wireless transmission mode in the field of industrial computer digital control to meet practical applications. Background technique [0002] Manual pulse generator (hereinafter referred to as MPG) is a commonly used human-machine input device in the field of industrial computer control. Its core components are rotary encoders and related setting and configuration knobs. MPG and industrial control computer generally adopt cable transmission, and the interface signal is single-ended voltage or differential type voltage. [0003] Wireless transmission manual pulse generator (hereinafter referred to as WMPG) is a replacement product for wired transmission MPG. It transmits user input information to CNC equipment through wireless mode, which can facilitate the remote user interface input...
