Data transmission control method, control system and electronic device

Abstract

This invention discloses a data transmission control method, a control system, and an electronic device, which sets the maximum allowable continuous transmission duration T during the data transmission process. MAX and maximum duty cycle D MAX Statistical analysis of the cumulative sent time T F and the cumulative suspension time T Z Determine the remaining allowed transmission time T. Y Is it greater than the required transmission time T for the data to be sent? D If so, then stop accumulating the paused time T. Z Send the data to be sent and add the actual sending time T of the data to be sent to the sent time. S Otherwise, the calculation requires pausing the transmission time T. T Pause T T Data transmission duration. This invention uses a hardware-implemented counter and calculation module to accurately count the cumulative transmission and pause times. Once the transmission time limit is reached, transmission is forcibly paused for a specific duration. This precisely controls the maximum allowable continuous transmission time and duty cycle, meeting the requirements for controlling heat generation and average power consumption. It keeps the main control chip temperature within a reasonable range, resulting in a very significant thermal control effect for small devices.

Description

Technical Field

[0001] This invention belongs to the field of data interaction control technology, specifically relating to control methods, control systems, and corresponding electronic devices when electronic devices perform data transmission. Background Technology

[0002] Most existing electronic devices have data transmission and reception capabilities, and with the increasing integration of main control chips, more and more electronic devices are becoming miniaturized. However, with the miniaturization of electronic devices, the requirements for average power consumption and heat dissipation are also increasing. For example, handheld visual ear picks have a particularly small PCB area and poor heat dissipation capabilities; if the RF chip operates for a long time, it can easily exceed 100°C, causing adverse effects on users and the device.

[0003] To effectively manage or minimize overheating caused by data transmission, existing technologies primarily rely on software to roughly control transmission time (including software statistics on transmission time and data volume). This approach fails to meet the requirement of precisely controlling the transmission duty cycle. For example, accumulating transmission time through MAC layer software and forcing a fixed-duration silence after reaching a threshold; while this method ensures the transmission time does not exceed the maximum allowed time, it cannot precisely control the transmission duty cycle. Another example is using the MAC layer to count the number of bytes or frames transmitted, limiting the rate (pausing transmission) when the number exceeds a threshold; this method, also software-based, has extremely low duty cycle control precision and cannot guarantee that the transmitted content will not exceed the maximum transmission time.

[0065] Among them, the maximum allowed continuous transmission duration T MAX Generally not less than 20ms; maximum duty cycle D MAX The effective value is 0% to 100%, and it is generally set to a value between 20% and 95%. Furthermore, each increment of the transmitted time accumulator counter is the unit of measurement required for the completion of one data transmission (e.g., if 100.5 µs is required for one data transmission, the counter increments by 101). Additionally, the paused time accumulator counter increments by one whenever the paused time reaches a unit of measurement (e.g., 1 µs).

[0066] See also Figure 2 As a preferred embodiment, the data transmission control system described above further includes: a cumulative count judgment module for transmitted time, a cumulative count judgment module for paused time, a duty cycle calculation module, and a duty cycle judgment module.

[0069] The data transmission control method, control system, and electronic device provided by this invention offer the following advantages: By using hardware-implemented counters and calculation modules, the transmission and pause times are precisely counted. Upon reaching the transmission time limit, transmission is forcibly paused for a specific duration before resuming. This precisely controls the maximum allowable continuous transmission time and duty cycle, simultaneously meeting the requirements for average power consumption and heat control without improving process technology. Furthermore, by precisely controlling the maximum allowable continuous transmission time and duty cycle, the chip temperature can be maintained within a reasonable range, and average power consumption can also be accurately controlled. This invention not only ensures 100% that the continuous transmission duration does not exceed the threshold but also precisely controls the duty cycle. This method is crucial for small devices, primarily because: 1. Precisely controlling the maximum transmission duration ensures that the device's heat generation is kept within acceptable limits; 2. Precisely controlling the duty cycle ensures that the average power consumption of the device during continuous operation is within acceptable limits.
