Embodiment Construction

[0033] The solution of the present invention is described below through specific embodiments and in conjunction with the accompanying drawings. For the overall flow chart, please refer to figure 1 As shown, the specific process is as follows:

[0034] 1. Dynamic gain

[0035] This system uses 12-bit precision AD for signal acquisition. Transmission of 12-bit data requires higher bandwidth. In order to save bandwidth and meet system requirements, it is converted into 8-bit data transmission. In order not to reduce the effective range of data, it is necessary to find the most suitable 8-bit data transmission. In fact, for a large signal, its low-order data is of little significance, and for a small signal, its high-order data is all 0, which has no value. Therefore, this example adopts the dynamic gain method to extract the most effective 8 bits for a frame of data. The specific method is: arrange a frame of 12-bit data, find the maximum value, judge how many of its high bits...

Abstract

The present invention discloses a wireless data transmission method. Said method includes the following steps: (1), system makes data acquisition; (2), making the described data undergo the process of dynamic gain treatment; (3), data compression; (4), interlaced error-collection ecoding; and (5), wireless transmission. Said invention can be used for implementing electrocardiogram (ECG) data transmission in medical distant-monitoring process.

Description

【Technical field】 [0001] The invention relates to a wireless data transmission method, in particular to a wireless data transmission method used in a medical digital telemetry monitoring system. 【Background technique】 [0002] A medical telemetry monitor is a typical embedded system consisting of a transmitter box, a receiver and a central monitoring station. Such a system generally carries several wireless transmitter boxes as a front-end patient data collection system. The transmitter box communicates with the receiver wirelessly. The transmitter box measures physiological signals such as electrocardiogram (ECG), blood oxygen saturation (SPO2), non-invasive blood pressure (NIBP) and other physiological signals of the human body through sensors and detection circuits, and sends the calculated and processed physiological parameter values ​​and waveforms to the receiver through wireless means. machine. [0003] In wireless communication, data is sent bit by bit on the chan...
