[0035] In the embodiment of the present invention, the product has two main technical indicators: the control range of respiratory rate is 5-35 times / minute, the control range of heart rate is 45-135 times / minute, and the control accuracy of breathing and heart rate is ±1 time / minute.

[0036] like Figure 6 As shown, in one embodiment, when the performance detection device for sleep monitoring mattress is working, the main control module collects key values ​​and performs numerical calculations; if the value exceeds the limit, the previous value is restored; if the value does not exceed the limit, the display value is output and a control signal is output.

[0037] The display module 204 is used to display the respiratory rate and the heart rate. The display module 204 can be a digital tube or a display screen.

[0038] In the above embodiment, the detection equipment includes a simulated human body and a control device, and the simulated human body and the control device are connected by cables and pipelines; the breathing frequency and the heart rate are set by the setting module, the lung simulator and the heart simulator are controlled by the main control module to move according to the set breathing frequency and heart rate, and the breathing frequency and the heart rate are displayed by the display module; the display result of the display module is compared with the monitoring result of the sleep monitoring mattress, so as to realize the detection of the overall performance of the sleep monitoring mattress; and, the present invention integrates the lung simulation air path module, the main control module, etc. separately into the control device, and the control device is placed separately from the mattress. Only the lung simulator and the heart simulator are in action in the human body simulation part. Through the clever electrical and structural design, the mechanical vibration signal of the control part is avoided from being superimposed on the simulated heartbeat and breathing signals, and the actual human body's vital sign signals are perfectly simulated to realize efficient detection of the performance of the sleep monitoring mattress.

[0039] Optionally, in one embodiment, Figure 4 As shown, the lung simulation air circuit module includes an air pump 401, a first three-way valve 402, a second three-way valve 403, a third three-way valve 404, a first normally open valve 405, a second normally open valve 406, a normally closed valve 407 and a pressure relief valve 408.

[0040] The first three-way valve 402 is connected to the air pump 401, the first normally open valve 405 and the second three-way valve 403 through a pipeline; the second three-way valve 403 is connected to the first three-way valve 402, the second normally open valve 406 and the third three-way valve 407 through a pipeline; the third three-way valve 404 is connected to the second three-way valve 403, the pressure relief valve 408 and the lung simulator through a pipeline.

[0041] In the above embodiment, the lung simulation air circuit is inflated by an air pump, and the lung simulator is operated according to the set breathing frequency by controlling the operating frequency of the three clamp valves. The lung air circuit is simulated through the above-mentioned pathway, and the lung simulator is cooperated with the lung simulator to realize the simulation of human lung respiratory signs.

[0042] Optionally, in one embodiment, Figure 3 As shown, the main control module 203 includes a controller MCU, a first solid-state relay U1, a second solid-state relay U2 and a third solid-state relay U3.

[0043] The first DC voltage output terminal (+5V) of the power module 201 is connected to the controller MCU, the first solid-state relay U1, the second solid-state relay U2 and the third solid-state relay U3 respectively.

[0044] The second DC voltage output terminal (+12V) of the power module 201 is connected to the power input terminal L1 of the first solid-state relay U1, the second solid-state relay U2 and the third solid-state relay U3 respectively.

[0045] The power output terminal T1 of the first solid-state relay is respectively connected to the first normally open contact K5, the normally closed contact K3 and the second normally open contact K2 in the lung simulation gas circuit module 205.

[0046] The power output terminal T1 of the second solid-state relay is connected to the heart simulator 504 through a cable. In this embodiment, a cable connector 508 is provided on the control device 200 and the simulated human body 100 for connecting the cable. The cable connector can be an aviation plug socket.

[0047] The power output terminal T1 of the third solid-state relay U3 is connected to the air pump A-009 in the lung simulation air circuit module 205.

[0048] The three signal output terminals of the controller MCU are respectively connected to the signal input terminals of the first solid-state relay U1 , the second solid-state relay U2 and the third solid-state relay U3 .

[0049] The power module 201 is responsible for converting the input 220V AC power into three sets of output power through the switch K1 and the fuse ACMate. One set of 5V DC power provides the working voltage of the main control module, one set of 12V DC power is responsible for providing power for the heart simulator, and another set of 12V DC power provides power for the lung simulation gas circuit module. The air pump is connected to the 220V AC power supply.

[0050] In the above embodiment, the controller MCU controls the action of the air pump in the lung simulation air circuit module through the third solid-state relay U3, and controls the first solid-state relay U1 to output a second DC voltage to the first normally open contact K5, the normally closed contact K3 and the second normally open contact in the lung simulation air circuit module according to the set breathing frequency, thereby realizing the control of the action frequency of the above three clamping valves, and cooperating with the lung simulator in the simulated human body to realize the simulation of human lung respiratory signs.

[0051] Specifically, when the power module has no DC voltage output to the lung simulation air circuit module, the first normally open valve and the second normally open valve are opened, and the normally closed valve is closed. At this time, the air pumped in by the air pump directly flows to the atmosphere, and at the same time, the pressure plate in the airbag cover is deformed and recovered, and the air in the airbag is discharged; when the power module has a DC voltage output to the lung simulation air circuit module, the first normally open valve and the second normally open valve are closed, and the normally closed valve is opened. At this time, the air pumped in by the air pump enters the airbag, and at the same time, the pressure plate is deformed. When the airbag is inflated to a certain extent, because the pressure reaches the set value, the pressure relief valve has a protective effect and discharges excess gas into the air. For example, the setting module 202 is set to breathe 30 times per minute, and the main control module 203 controls the second DC voltage (12V level) output by the voltage module 201 to be energized 30 times per minute. Half of each power-on cycle has a 12V level and half of the time has no 12V level.

[0052] Optionally, in one embodiment, the controller MCU controls the second solid-state relay U2 to output a second DC voltage to a heart simulator in the simulated human body according to a set heartbeat frequency, thereby simulating human heartbeat signs.

[0053] Optionally, in one embodiment, Figure 5 As shown, the simulated human body comprises a base and an upper cover 502, wherein the upper cover 502 covers the base to form a receiving cavity. The upper cover 502 is provided with a cable connector 508 and an airway connector 509, which are used to connect the cable and the airway, respectively.

[0054] The base includes a mounting base plate 501 and a vital sign conduction pad 503 which are stacked and fixed in sequence. A heart simulator 504 is fixed on the base through a mounting bracket 505, and a lung simulator is fixed on the base. In this embodiment, the vital sign data is conducted externally by fixing the vital sign conduction pad 503 on the base. The vital sign conduction pad can be a rubber pad or a silicone pad.

[0055] The lung simulator includes an airbag 506 and an airbag cover 507. A plurality of vents are arranged on the side wall of the airbag cover 507. The airbag 506 and the airbag cover 507 are both fixed on the base. The airbag cover 507 covers the airbag 506. The inner top surface of the airbag cover 507 has a deformable pressure plate (not shown).

[0056] During the operation of the detection equipment, when the airbag 506 is in an uninflated state, the deformable pressure plate presses the airbag 506 to discharge the gas in the airbag 506; when the gas enters the airbag, the pressure plate is deformed. When the airbag is inflated to a certain extent, the pressure reaches the set value, and the pressure relief valve produces a protective effect, discharging excess gas into the air.

[0057] In the above embodiment, the lung simulator is formed by the airbag and the airbag cover, and the respiratory signs of the human lung are simulated through the interaction between the deformable pressure plate and the airbag.

[0058] Optionally, in one embodiment, a counterweight device is further provided in the simulated human body, and the counterweight device can be fixed on the top of the airbag cover (not shown in the figure). The counterweight device can be bagged iron sand.

[0059] Optionally, in one embodiment, the heart simulator may use an electromagnet to simulate the beating signs of a human heart through radial movement of the electromagnet.
