the flexible sensor has the advantages of high sensitivity, quick response and the like, and is used for measuring monitoring data related to the operation condition of the electromagnetic pulse valve, and is high in sensitivity and quick in response.

In addition, the diaphragm is made of soft materials, for example, made of rubber materials, is easy to age, and can cause the problems of elasticity reduction and even cracking after long-term use, and the diaphragm is a key component of the electromagnetic pulse valve and directly influences the performance of the electromagnetic pulse valve, so that the state of the diaphragm is important to grasp in time. According to the embodiment of the application, the flexible sensor is coupled to the diaphragm, the change of the pressure data detected by the flexible sensor can reflect whether the diaphragm is aged or damaged, and the data such as pressure, temperature, humidity and the like detected by the flexible sensor can reflect the working environment near the diaphragm, so that the state and the service life of the diaphragm can be evaluated or predicted.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
The diaphragm assembly in the embodiment of the application is used for constructing an electromagnetic pulse valve and is used for sealing and isolating an air inlet and an air outlet in the electromagnetic pulse valve, so that the pulse valve can realize a switching action, and the diaphragm assembly in the embodiment of the application refers to a main diaphragm 101.
Fig. 4 is a schematic structural view of a diaphragm assembly for an electromagnetic pulse valve according to an embodiment of the present application, and fig. 5 is a sectional view of a diaphragm assembly for an electromagnetic pulse valve according to an embodiment of the present application. As shown in fig. 4 and 5, the diaphragm assembly includes a diaphragm 212, and a flexible sensor 311 for acquiring monitoring data is coupled to the diaphragm 212, where the monitoring data is used to acquire an operating condition of the electromagnetic pulse valve.
Specifically, the flexible sensor 311 is a sensor made of flexible material, and has good flexibility, ductility, bending property, and the like, and the flexible sensor 311 can be arranged arbitrarily according to application scenarios due to flexible materials and structures. The flexible sensor 311 may be classified into a flexible resistive sensor, a flexible capacitive sensor, a flexible piezoelectric sensor, a flexible inductive sensor, and the like, as distinguished from the sensing mechanism.
In a specific implementation, the flexible resistive sensor is generally formed by placing a resistive layer, a short-circuit layer, a flexible contact and an electrode capable of collecting sensing information on a substrate, for example, the flexible resistive pressure sensor is generally formed by overlapping the short-circuit layer and the resistive layer under the action of pressure, so that the resistance of a system circuit is changed, and then a pressure value is obtained. Unlike flexible resistive sensors, which change resistance by changing the size of the contact surface to obtain measurement data, flexible capacitive sensors generally employ a parallel plate capacitance-based device, which changes the capacitance of the sensor by changing the distance between the plate capacitors. Taking a pressure sensor as an example, the distance between the plate capacitors is reduced by applying pressure from the outside, so that measurement data are obtained. The flexible inductance sensor realizes data measurement by utilizing the self inductance of a coil or the change of mutual inductance coefficient. A flexible piezoelectric sensor is one in which the dielectric material is polarized internally when subjected to external forces in a particular direction, resulting in opposite charges on its opposite surfaces, which differential can be used for measurement.
The flexible sensor 311 includes a substrate and a conductive material, the flexible sensor 311 is made of a flexible substrate, and the material is generally required to be light, thin, transparent, stretchable, bendable, corrosion-resistant, and the like, and Polydimethylsiloxane (PDMS) is a relatively common flexible substrate material, so that the flexible sensor has the characteristics described above, is easy to obtain, and has stable chemical properties.
The conductive material of the flexible sensor 311, that is, the metal material is mainly used for manufacturing electrodes and wires, and in general, the flexible sensor 311 does not use common metal, but adopts nano particles or nano wires of metal, and the material has better conductivity and is easy to realize as a film.
The flexible sensor 311 is classified into a pressure flexible sensor, a gas flexible sensor, a humidity flexible sensor, a temperature flexible sensor, a strain flexible sensor, a magneto-impedance flexible sensor, a heat flow flexible sensor, and the like according to the purpose, and of course, the purpose may be combined.
That is, the flexible sensor 311 having a corresponding function may be selected according to the kind of the required monitoring data, which is one or a combination of several of temperature, pressure, humidity for the embodiment of the present application. For example, in one embodiment, pressure data is required, and a flexible pressure sensor is used, and changes in the pressure data measured by the flexible pressure sensor reflect the "opening" of the diaphragm 212 as it moves, thereby acquiring the operating state of the electromagnetic pulse. In another embodiment, pressure data and temperature data are needed, and the pressure data and the temperature data measured by the pressure and temperature flexible sensors are used for reflecting the running state of electromagnetic pulses.
It should be noted that, related technologies of the flexible sensor 311 have been widely disclosed, and reference is made to the related technologies for the working principle of the flexible sensor 311 and the related arrangement of the flexible sensor 311, which are not described herein.
Because the flexible sensor 311 has the advantages of high sensitivity, quick response and the like, the flexible sensor 311 is used for measuring monitoring data related to the operation condition of the electromagnetic pulse valve, and has high sensitivity and quick response. Meanwhile, the flexible sensor 311 is coupled to the diaphragm 212, and the switching of the operation condition of the electromagnetic pulse valve is triggered by the diaphragm 212, so that the response of the flexible sensor 311 is faster and the sensitivity is higher, the problem that the operation condition of the electromagnetic pulse valve is known by arranging the sensor in the prior art is effectively solved, the acquired operation condition of the electromagnetic pulse valve is insufficient in accuracy due to poor measurement accuracy and response time of the sensor, and the beneficial effect of high accuracy of the acquired operation condition of the electromagnetic pulse valve is realized.
In addition, the diaphragm 212 is made of soft material, for example, made of rubber material, which is easy to age, and after long-term use, the problem of elasticity reduction and even cracking occurs, while the diaphragm 212 is a key component of the electromagnetic pulse valve, which directly affects the performance of the electromagnetic pulse valve, so that it is important to grasp the state of the diaphragm 212 in time. According to the embodiment of the application, the flexible sensor 311 is coupled to the diaphragm 212, so that the change of pressure data detected by the flexible sensor 311 can reflect whether the diaphragm 212 is aged or damaged, and the data such as pressure, temperature, humidity and the like detected by the flexible sensor 311 can reflect the working environment near the diaphragm 212, thereby being beneficial to evaluating or predicting the state and service life of the diaphragm 212.
It should be noted that, the method for acquiring the operation state of the electromagnetic pulse valve according to the monitoring data collected by the flexible sensor 311 belongs to the prior art, and also does not belong to the scope of protection claimed in the embodiment of the present application, and is not described herein.
In an embodiment of the present application, as shown in fig. 4 and 5, the diaphragm assembly further includes a first fixing plate 211 and a second fixing plate 213 respectively disposed on upper and lower end surfaces of the diaphragm 212, and the flexible sensor 311 may be disposed on the first fixing plate 211 or the second fixing plate 213. As shown in fig. 2 to 3, when the electromagnetic pulse valve is in the "open" state, the compressed gas is blown through the gas outlet 109a, and the pressure is large; the electromagnetic pulse valve is in a "closed" state, the air outlet 109a is disconnected, and the pressure is small. Since the second fixing plate 213 faces the air outlet 109a, and the flexible sensor 311 is disposed on the second fixing plate 213, the pressure change of the air outlet 109a can be timely and accurately obtained, so as to accurately determine the operation state of the electromagnetic pulse valve, so that the flexible sensor 311 is preferably disposed on the second fixing plate 213.
In an embodiment of the present application, the second fixing plate 213 is coated with a soft cladding 214, and the flexible sensor 311 is sandwiched between the second fixing plate 213 and the soft cladding 214.
Specifically, the first fixing plate 211 and the second fixing plate 213 are both metal plates, for example, stainless steel plates. The soft cladding 214 is a cladding layer formed by vulcanizing rubber on the second fixing plate 213. Vulcanization is also known as crosslinking and curing. Adding cross-linking assistant such as vulcanizing agent and accelerator into rubber, and converting linear macromolecules into three-dimensional network structure under certain temperature and pressure. Since sulfur was used at the earliest to achieve crosslinking of natural rubber, it is called vulcanization. It should be noted that, related technologies of vulcanization are widely disclosed, and reference is made to the related technologies of vulcanization, which are not described herein in detail.
The soft cladding 214 is soft and easily deformed by pressure changes. The second fixing plate 213 is hard, and is not easily deformed during the change of the gas pressure in the electromagnetic pulse valve. One surface of the flexible sensor 311 is abutted against the soft cladding 214, and the other surface is abutted against the hard second fixing plate 213, so that the gas pressure in the electromagnetic pulse valve can be accurately measured, and the measurement accuracy is improved. Therefore, the flexible sensor 311 is sandwiched between the second fixing plate 213 and the soft cladding 214, so that the sensitivity is higher and the accuracy is high.
In another embodiment of the present application, the flexible sensor 311 is disposed between the lower end surface of the second fixing plate 213 and the soft cladding 214, and the lower end surface of the second fixing plate 213 directly faces the air outlet 109a, so that the pressure change of the air outlet 109a can be obtained more timely and more accurately, so as to more accurately determine the operation state of the electromagnetic pulse valve.
Further, the flexible sensor 311 is communicatively connected to a remote terminal by means of a wireless connection or a wired connection, so as to transmit the monitoring data to the remote terminal.
For example, in one implementation of the present application, the flexible sensor 311 is wirelessly connected to a remote terminal via microwave transmission or network transmission.
For another example, in another implementation of the present application, the flexible sensor 311 is connected to a remote terminal by a wired connection, as follows: as shown in fig. 8, the flexible sensor 311 is connected with a wire 312 for transmitting the monitoring data to a remote terminal. One end of the wire 312 is in signal connection with the flexible sensor 311, and the other end of the wire 312 sequentially passes through the second fixing plate 213, the soft cladding 214 and the diaphragm 212 and extends out of the diaphragm assembly for connection with the remote terminal, so that the flexible sensor 311 transmits the monitoring data to the remote terminal through the wire 312.
In some embodiments, an adapter is further connected between the flexible sensor 311 and the remote terminal, and the adapter is used for performing analog-to-digital conversion, conditioning and other processing on the monitoring data, so that the flexible sensor 311 is directly connected with the adapter through a wire 312. At this time, the flexible sensor 311 transmits the detected data to the converter, and then transmits the data to the remote terminal after being processed by the converter. The remote terminal is arranged outside the electromagnetic pulse valve, and the adapter can be arranged inside the electromagnetic pulse valve or outside the electromagnetic pulse valve. It should be noted that, related technologies of a converter for performing analog-to-digital conversion, conditioning and other processes on monitored data have been widely disclosed, please refer to the prior art for the working principle and related setting mode of the converter, and the remote terminal may be an industrial personal computer (e.g. an embedded system), a personal computer, a notebook computer, a smart phone, a tablet computer, an internet of things device and a portable wearable device, where: the internet of things equipment can be intelligent sound boxes, intelligent televisions, intelligent air conditioners, intelligent vehicle-mounted equipment and the like; the portable wearable device may be a smart watch, smart bracelet, headset, or the like.
Further, as shown in fig. 7, the second fixing plate 213 is provided with a mounting groove 217 for mounting the flexible sensor 311, a wire groove 215 for mounting the wire 312 is provided on the lower end surface of the second fixing plate 213, and a through hole 216 for passing the wire 312 is provided at the bottom of the wire groove 215. The flexible sensor 311 is disposed in the mounting slot 217, and one end of the wire 312 is connected to the flexible sensor 311, and the other end passes through the through hole 216 of the wire slot 215 and extends out of the second fixing plate 213, as shown in fig. 5, 6, 9 and 10.
Specifically, the flexible sensor 311 is embedded in the mounting groove 217, and a wire 312 on one side extends along the wire groove and passes through the wire groove 215. For example, in one embodiment of the present application, the first fixing plate 211 and the second fixing plate 213 are circular plates coaxially disposed with the diaphragm 212, the mounting groove 217 is a ring groove coaxially formed in the second fixing plate 213, and the flexible sensor 311 is in a ring shape matching with the ring groove. The wire groove 215 extends along one virtual diameter direction of the second fixing plate 213, and one end of the bottom of the wire groove 215, which is close to the center of the second fixing plate 213, is provided with the through hole 216, and the wire 312 extends along the wire groove 215 and passes through the through hole 216 on the wire groove 215, thereby passing through the second fixing plate 213.
