[0022] The 4-core socket 2, the black rubber socket 7, the red rubber socket 8 and the buzzer 10 are installed in the mounting holes of the housing 6 by means of self-contained fasteners.

[0023] The green light emitting diode 3, the red light emitting diode 4 and the toggle switch 5 are installed in the installation hole of the front panel 1 by means of self-contained fasteners.

[0024] The circuit board 9 is mounted on the mounting ears of the housing 6 by means of screws.

[0025] The housing 6 and the front panel 1 are screen-printed with self-test alarm, hypoxia alarm, on, off, +28V, and GND for easy identification.

[0026] The connection relationship among the 4-core socket 2, the green LED 3, the red LED 4, the toggle switch 5, the black rubber socket 7, the red rubber socket 8, the circuit board 9, and the buzzer 10 is shown in FIG. Figure 6As shown. Among them, the oxygen monitor working state detection device is provided with 28V working voltage by an external DC regulated power supply through the black rubber socket J2 and the red rubber socket J1. The 4-core socket J3 is connected to J1, J2, and J3 inside the oxygen monitor working state detection device through a wire, wherein the 1st and 3rd pins of J3 are connected to J1 and J2 respectively, and the 2nd pin of J3 is connected to the self-test alarm circuit and the green light-emitting diode inside the oxygen monitor working state detection device. The 4th pin of J3 is connected to the hypoxia alarm circuit and the red light-emitting diode inside the oxygen monitor working state detection device. The oxygen monitor is connected to J3 through an external power cable, and the 1st and 3rd pins of J3 are used to power the oxygen monitor, and the different working state signals of the oxygen monitor are transmitted to the oxygen monitor working state detection device through the 2nd and 4th pins of J3. The 2-way signals received by the oxygen monitor working state detection device through J3 are high and low level signals generated by different working states of the oxygen monitor, which are used as the signal input of the oxygen monitor working state detection device and are connected to the self-test alarm circuit and the hypoxia alarm circuit respectively. When the 2nd pin con1-1 of the self-test alarm circuit terminal J3 of the working state detection device of the oxygen monitor receives a "low level", there is no forward voltage at both ends of the green light-emitting diode, the green light-emitting diode is in a cut-off state, and the light is off; when receiving a "high level", there is a forward voltage at both ends of the green light-emitting diode, it is in a conducting state, and the light is on. When the 4th pin con1-2 of the hypoxia alarm circuit terminal J3 of the working state detection device of the oxygen monitor receives a "high level", there is no forward voltage at both ends of the red light-emitting diode 4, the light-emitting diode is in a cut-off state, and the light is off; when receiving a "low level", there is a forward voltage at both ends of the red light-emitting diode 4, it is in a conducting state, the light is on, and the switch S1 is turned on, and the buzzer 10 sounds. The circuit board mainly includes two groups of resistors R1 and R2, which are connected to the green light-emitting diode and the red light-emitting diode respectively.

[0027] The working state detection device of the oxygen monitor determines the working state of the oxygen monitor according to the different signals output by the oxygen monitor in different working states. The oxygen monitor can be intuitively expressed from the ready state, normal operation, and hypoxia alarm fault state through indicator lights and buzzers. Specifically, when the self-test alarm circuit end of the working state detection device of the oxygen monitor receives a "low level" signal, the green light-emitting diode goes out, indicating that the oxygen monitor is working normally; when receiving a "high level" signal, the green light-emitting diode lights up, indicating that the oxygen monitor is not working normally (ready state or oxygen concentration is too high); when the oxygen monitor working state detection device self-test alarm circuit end receives a "low level" signal, the green light-emitting diode lights up, indicating that the oxygen monitor is not working properly (ready state or oxygen concentration is too high); when the hypoxia alarm of the working state detection device of the oxygen monitor When the line end receives a "low level" signal, the red LED lights up, indicating that the oxygen monitor is not working properly (ready state or oxygen concentration is too low); when receiving a "high level" signal, the red LED goes out, indicating that the oxygen monitor is working properly; after the oxygen sensor working state detection device is powered on and connected to the oxygen monitor with a power cable, the red LED (hypoxia alarm) and green LED (self-test alarm) of the detection device are both on during the ready state stage. If the red LED (hypoxia alarm) and green LED (self-test alarm) of the detection device are not on for a period of time during the ready state stage, the oxygen monitor is working properly. If the toggle switch on the panel of the detection device is turned to "on", when the red LED light is on (hypoxia alarm), the corresponding buzzer should sound at the same time.

[0028] The oxygen monitor working status detection device can detect the working status of multiple sets of oxygen monitors at one time, and can increase or decrease the number according to actual use needs, thereby greatly saving manpower and financial costs.
