[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Example 1

[0024] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please refer to Figure 1 As shown, an embodiment of the utility model provides a multi-station breathing test device, which includes: a plurality of groups of three-piece air-controlled ball valves 102 and solenoid valves 103 arranged in groups; the solenoid valve 103 has a control module, and each of the control modules is provided with a control code compiled in a unified rule and different; the solenoid valve 103 is connected to the control end of the three-piece air-controlled ball valve 102; each of the three-piece air-controlled ball valves 102 has a test tube 105 connected at one end, and the other end is connected through a pipeline and connected to an air inlet 104; a PLC unit 107 is electrically connected to a collector arranged on the three-piece air-controlled ball valve 102 through a data line, and is electrically connected to the control module of the solenoid valve 103 through a control line.

[0026] In the above embodiment, the multi-station breathing test device solves the problem of low efficiency of the current single-station test by using multiple groups of three-piece air-controlled ball valves 102 and solenoid valves 103. Specifically, each test station is equipped with a group of three-piece air-controlled ball valves 102 and a solenoid valve 103, and is centrally controlled by a PLC unit 107. The control module of each solenoid valve 103 is programmed with different control codes to distinguish different test positions. During operation, the PLC unit 107 is connected to the control modules of the air-controlled ball valve 102 and the solenoid valve 103 through a data line and a control line, respectively. When testing, the PLC unit 107 can control the corresponding solenoid valve 103 to open or close through the control code as needed, thereby controlling the required test position to open or close. Since each test position is programmed using a unified rule and different control codes, the operation of each test position can be accurately controlled, interference and collision can be avoided, and breathing tests can also be performed simultaneously, thereby improving test efficiency.

[0027] The above-mentioned multi-station simultaneous testing can greatly improve the efficiency of respiratory testing and save time and human resources. Compared with multiple single-station equipment, this multi-station respiratory testing device only requires one set of equipment, which can reduce equipment costs and reduce occupied space. In addition, each test position can have an independent control code, which can achieve accurate control and operation and avoid interference and conflict.

[0028] As an example, a multi-station breathing test device, wherein the PLC unit 107 can preferably use a CX3G-32MT programmable controller as a control unit, through an RS485 control line, based on the MODBUS protocol, using different coding bits, corresponding to different groups of control modules of the solenoid valve 103, for example, the above-mentioned stations can be set to 15, or more, taking 15 as an example, can be hexadecimal encoded, from the first group to the 15th group arranged in sequence as 0x0000, 0x0001, 0x00003, x00004, x00005, x00006, x00007, x00008, x0009, x000A, x000B, x000 0C, x000D, x000E, as the coding, in addition, a general code x000F and a main switch code x0064 can be set, that is, when the address sent by the PLC corresponding to the main switch is x0064, the main switch is turned on or off, when the main switch is turned on, the control module of the above-mentioned solenoid valve 103 can be controlled. For example, when the code in the control instruction sent by the PLC unit 107 is 0x0001, the control module of the solenoid valve 103 of the second group responds, and the control modules of other groups do not respond, thereby accurately controlling the workstation. When all control is required, an instruction coded as x000F can be sent; in addition, it can be divided into several groups in the form of grouping and then controlled by group using the group address, making it more flexible.

[0029] Example 2

[0030] The embodiment of the utility model provides a multi-station breathing test device, wherein a plurality of groups of the three-piece air-controlled ball valves 102 and the solenoid valves 103 are arranged in a device cabinet 101; wherein the air inlet 104 and the test tube 105 pass through the device cabinet 101.

[0031] The three-piece air-controlled ball valve 102 and the solenoid valve 103 are carried and packaged in a device cabinet 101 so that they can be managed in a unified manner, and the data line and the control line can be plugged into the PLC unit 107 through an interface. The PLC unit 107 can also be installed on the device cabinet 101 for easy operation.

[0032] As an example, the three-piece air-controlled ball valve 102 is preferably a KL-DN20 three-piece air-controlled ball valve 102, which has the characteristics of zero resistance and large flow, and is made of 304 stainless steel, which has corrosion resistance. In order to control the opening and closing speed, the device is also equipped with a speed regulating valve to reduce the instantaneous impact of the airflow, and the valve body opens and closes more smoothly. The solenoid valve 103 preferably adopts a 4V110 solenoid valve, which is used to control the on and off of the three-piece air-controlled ball valve 102. Its operating frequency can be set to 10 times / second, with fast response and stable operation. The air pressure used is 4-7bar.

[0033] As a preferred embodiment, the test tube 105 is a silicone tube. Since the silicone tube has high high temperature resistance and good low temperature resistance, the silicone tube has good flexibility and elasticity in a low temperature environment, and is not easy to harden or become brittle, so that the test tube 105 has good weather resistance, and the silicone tube has good corrosion resistance to many chemical substances, thereby increasing the service life of the test tube 105.

[0034] As a preferred embodiment, the PLC unit 107 is provided with a touch screen, through which visual control can be performed, and the control is performed by touch, and the feedback status can be intuitively seen on the screen.

[0035] As an example, using a touch screen, the above-mentioned related valves can be controlled in a visual way. They can be set as corresponding buttons to achieve on-off control. When controlling the on-off of each valve, gray can be used to indicate that the valve body is in a closed state. Touch the switch point with your finger to send a control code for the switch. After receiving status feedback, the switch color turns green and the switch is turned on. Release the button to keep the green on state. Touch the button again to send a closing command. The switch color changes from green to gray and the valve body is closed. Multiple switches can be turned on at the same time and work at the same time. At this time, press the main switch to turn on, the color turns red, and all the opened valve body switches are closed at the same time. When the main switch is on, pressing the valve body switch will not respond. Only when the main switch is turned off again and the color turns gray, can the valve body switch be started.

[0036] As a preferred embodiment, the front of the device cabinet 101 is provided with organic glass 108 for sealing, and the test tube 105 passes through the organic glass 108, which has good light transmittance and can be transparent to most visible light, making the interior of the device easy to observe and inspect. In addition, it also has good sealing performance and can effectively isolate the external environment and internal components.

[0037] As a preferred embodiment, a partition 106 is provided in the device cabinet 101, and the three-piece air-controlled ball valve 102 and the solenoid valve 103 are distributed in groups on the partition 106 and the bottom layer. Figure 1 As shown, two layers of partitions 106 can be set inside the above-mentioned device cabinet 101 to divide the interior into three layers. Five groups of three-piece air-controlled ball valves 102 and solenoid valves 103 are respectively set on the bottom layer and the two partitions 106, forming a respiratory test device with fifteen test stations.

[0038] As a preferred embodiment, handrails 109 are provided on both sides of the device cabinet 101, which can make transportation more convenient. In addition, universal wheels (not shown in the figure) can be provided at the lower end of the device cabinet 101 to further facilitate the movement of the device.
