Ultrasonic device and method for abnormality detection and recovery of ultrasonic device

Abstract

The invention provides an ultrasonic device and a method for abnormality detection and recovery of the ultrasonic device. The ultrasonic device comprises a probe, an input circuit, an output circuit and two connected DSPs. The input circuit and the output circuit are connected with the probe respectively. All DSPs are connected with a display control device, the input circuit and the output circuit. The method comprises the steps that any one of the DSPs sends detection signals to the other DSP periodically and replies when receiving detection signals sent by the other DSP; when the DSP confirms that replied signals of the other DSP are not received for many times continuously, a reset signal is sent to the other DSP; after the reset signal is sent out, the DSP continues to send detection signals, and if reply signals of the other DSP still are not received within a set time period, it is determined that the other DSP is abnormal. According to the ultrasonic device and the method for abnormality detection and recovery of the ultrasonic device, reliability and stability of a hardware system of the ultrasonic device are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ultrasonic device and an abnormality detection and recovery method thereof. Background technique [0002] Medical electronic equipment is based on modern electronic technology, semiconductor technology, etc. At the same time, medical machinery, biomedicine, new materials and other disciplines are applied to medical research, clinical diagnosis, treatment, in-depth analysis, analysis of equipment in the fields of health care and rehabilitation. [0003] Ultrasonic diagnostic equipment uses the propagation of ultrasonic waves in the human body to obtain structural information about relevant tissues or organs of the human body. At present, ultrasonic diagnostic instruments use one or more array element probes. The probe is subjected to high-voltage pulses to generate ultrasonic waves, which are focused and transmitted into the human body to receive echoes scattered and r...

Problems solved by technology

[0010] 1) The amount of color ultrasound image data is large, and the receiving and sending of image data is completed by the same DSP. In addition, the DSP also needs to complete the task of communicating with the PC and analyzing the commands sent by the PC. Therefore, the single-chip DSP has a large amount of operating tasks, resulting in a decrease in system performance. ;

[0011] 2) There is only one main control chip DSP. Once the system runs away or crashes, the system can only be manually restarted, and the monitoring system cannot be implemented, which may cause medical accidents; immediate manual restart may not work, which may cause medical accidents
