[0049] Specifically, in the embodiment of the present invention, by optimizing and integrating the respiratory pressure signal, electrocardiogram signal, video signal, heating function, lighting function, door control function, and Hall magnet hatch detection function on the same control unit module circuit board, the number of circuit boards is reduced. The unified encoding transmission of network transmission signals is realized by sharing the network communication module.

[0050] Such as Figure 3 As shown, the respiratory pressure sensor U2:MSP40-G detects the external pressure through its own air holes, converts the pressure signal into a differential voltage signal through the change of the internal shrapnel resistance, and then sends the differential analog signal to the ADS1292R physiological signal acquisition chip U1 for processing. The ADS1292R then encodes the pressure signal to a certain extent and sends it to the ARM chip U4 for network protocol encoding and transmission to the host computer for processing. And a respiratory gating signal will be output synchronously.

[0051] Path for collecting electrocardiogram signals: The ECG differential analog signal is sent to the ADS1292R physiological signal acquisition chip for processing. The ADS1292R then encodes the ECG differential analog signal to a certain extent and finally becomes a binary digital signal, which is sent to the ARM for network protocol encoding and transmission to the host computer for processing. And a heartbeat gating signal will be output synchronously.

[0052] Specifically, the ADS1292R chip is initialized through the SPI interface to make the chip in the continuous acquisition mode. Finally, the interrupt is enabled, and the data acquisition process is handed over to the interrupt for processing. The respiratory pressure sensor U2:MSP40-G detects the external pressure through its own air holes, converts the pressure signal into a differential voltage signal through the change of the internal shrapnel resistance, and then sends the differential analog signal to the ADS1292R physiological signal acquisition chip U1 for processing into a digital signal. Then the pressure digital signal is encoded to a certain extent and sent to the ARM chip U4 for network protocol encoding and transmission to the host computer for processing. And the circuit board will output a respiratory gating signal synchronously. The electrocardiogram sampling data is digitally filtered, and the electrocardiogram gating signal is calculated. The digital filtering method is 8-byte sliding mean filtering, which can be configured to be used 0 to 3 times according to the noise situation. It is actually used 3 times.

[0053] After digital filtering, the data enters the threshold algorithm to calculate the threshold for triggering the electrocardiogram (ECG) gating. The threshold calculation method is 70% of the peak-to-peak value within the most recent 4 seconds. Therefore, the gating threshold is updated every 4 seconds, and the gating output signal will also be generated. The ECG differential analog signal is sent to the ADS1292R physiological signal acquisition chip for processing. The ADS1292R then encodes the ECG differential analog signal to finally obtain a binary digital signal, which is sent to the ARM for network protocol encoding and transmitted to the host computer for processing. And a heartbeat gating signal will be output synchronously. The ECG gating algorithm is implemented through a state machine. After the data passes through the threshold, a gating high-level signal is output. After a data input hold of 6% of the sampling rate, it is detected again and a gating low-level signal is output.

[0054] The heart rate can be calculated through the gating algorithm. By accumulating the number of samples, the heart rate is calculated every 4 ECG gating detections. Therefore, the maximum heart rate that can be measured by this algorithm is theoretically 1000 BPM, and the minimum measurable heart rate can be calculated based on the threshold detection frequency as 15 BPM. The maximum heart rate error calculated theoretically is ±0.8%, and the maximum error only occurs when measuring the maximum heart rate (1000 BPM), and the error will decrease significantly as the heart rate value decreases. If a lower error is desired, it can be achieved by accumulating the number of samples for a longer time.

[0055] For the situation of unstable ECG signals and baseline drift, the problem of inaccurate gating calculation caused by the slow change of the baseline can be solved by calculating the real-time baseline. The method for calculating the baseline is as follows: Take the most recent sampling data at 10% of the sampling rate as the calculation window, sort the data from smallest to largest, and take the average of the smaller 40% of the data within the window as the baseline value of the current sampling point. After the sampling point passes through the filtering algorithm, subtract the baseline value calculated at this point and then perform the gating algorithm to obtain a more accurate gating signal.

[0056] As Figure 5 shown, the ARM GPIO outputs a fixed-frequency PWM to control the switching of the MOS transistor M1, thereby heating the heating temperature pad. By changing the PWM duty cycle, the temperature of the heating film can be controlled within a certain range. The ARM GPIO outputs a 20K Hz PWM to control the switching of the MOS transistor M2, thereby lighting the LED. By changing the PWM duty cycle, the brightness of the LED can be controlled.

[0057] The utility model provides a multifunctional integrated control system suitable for an animal cabin, that is, the system includes a first device for collecting respiratory pressure signals in the animal cabin, a second device for collecting electrocardiogram signals in the animal cabin, a third device for collecting video signals in the animal cabin, a fourth device for realizing a heating function for the animal cabin, a fifth device for realizing a lighting function for the animal cabin, and a sixth device for realizing a door control function for the animal cabin; the first device, the second device, the third device, the fourth device, the fifth device and the sixth device are integrated on a same control unit module circuit board; a first control circuit is provided in the second device; a first control chip is provided in the first control circuit; the twenty-ninth pin of the first control chip is connected to one end of a second resistor; the other end of the second resistor is respectively connected to one end of the third resistor, one end of the fourth resistor, one end of the first resistor and one end of the first capacitor;

[0058] The other end of the third resistor is connected to the 30th pin of the first control chip; the 28th pin of the first control chip is connected to the other end of the first capacitor and the other end of the fourth resistor respectively. This can realize the unified coding transmission of network transmission signals.

[0059] In other words, this solution integrates hardware resources to reduce costs, improve software execution efficiency, and reduce failure rates. With the help of relevant circuits, small animals' ECG and respiratory signals can be monitored in real time. At the same time, real-time video monitoring and display are also available. Warehouse heating, lighting, door status recognition, constant temperature control and other functions are integrated into a control system. The above information can be transmitted to the host computer via the network for storage and real-time display.
