Description

Touch monitor interlocking chemical leak detection system

The present invention relates to a chemical leak detection system for detecting a chemical leak.

In more detail, the leak detection module includes a touch monitor that can input and change the detection material, setting content, and setting conditions, along with the result of the leak judged by the leak detection module. it's about

A leak sensor for detecting water leakage and oil leakage is classified into a cable type leak sensor, a band type leak sensor, a modular type leak sensor, and the like.

The cable type leak sensor is a leak sensor and leak detection leak sensor that detects leaks of various liquids (water, oil, etc.) and informs the leak point accurately and quickly. In the detection of water leakage and oil leakage, a potential difference is generated by the resistance of the leaked liquid in the current flowing along the conducting wire, so that the leakage and oil leakage can be confirmed.

However, the cable type leak sensor is expensive to install, and since the sensor cable length is fixed, remote sensing is difficult. In addition, since it is necessary to use a separate bracket to install the sensor, it is difficult to install, and there are additional costs. there is also

The band-type leak detection sensor detects leaks through this because the resistance value changes when the fluid comes into contact with the wire while the current flows through the wire. The band-type leak detection sensor can detect leaks in a large area at a low cost and is easy to install. In addition, the price is high compared to the performance, the installation is cumbersome because a bracket to be fixed to the floor must be separately installed during installation, and there is a problem that there is no connection device other than the relay contact method when connecting an external device.

The modular leak sensor places the photosensor inside the plastic case, and when there is liquid leaking between the light emitting part and the light receiving part of the photosensor, the leak is detected as the beam irradiated from the light emitting part is not received by the light receiving part. The modular leak sensor can detect leak-risk parts at low cost, is easy to install, and has the advantage that it can alarm itself regardless of peripheral devices and there is no error due to high humidity. There is a problem that only leaks can be checked, and there is a problem of compatibility that it is difficult to connect to a peripheral device. In addition, since it is necessary to plan a separate sensor fixing method, it takes a long time to install the product, and since only a specific part of the leak risk area can be detected, it is difficult to detect when the leak location is changed.

On the other hand, since each of the above-described leak sensors employs only one detection method, there is a problem in that if you want to change the detection method, you must additionally purchase a leak sensor suitable for it. Because it does not have a self-diagnosis function, the reliability of the product is lowered, and there is a problem that the lifespan of the product is shortened due to the absence of the self-diagnosis function.

As shown in the accompanying drawings above, the touch monitor-linked chemical leak detection system 100 according to the present invention is, as in FIG. 1, a leak detection sensor 200, a leak detection module 300 and a touch monitor 400. may include

Among the components, the leak detection sensor 200 is for detecting chemical leakage, and two embodiments may be presented.

First, as in FIGS. 2 and 3, the leak detection sensor 200 of the first embodiment includes a base pad 210 made of an insulating and chemical resistant material, and Nos. 1-4 buried in parallel in the width direction of the base pad. Consists of conductive wires 221 to 224, of which the first and second conductive wires 221 and 222 are sensing conductive wires that detect the leakage of chemicals as they come into contact with the leaking chemicals, and the third and fourth conductive wires 223 and 224 ) is covered by an insulator (base pad) to prevent it from coming into contact with chemicals, and it detects whether the power is connected or not and changes in resistance.

The base pad 210 may be made of any one selected from PET, PVC, PU, PE, PP, PI, PC, PMMA, ABS, rubber resin, silicone, and Teflon.

In addition, it is preferable that the base pad 210 has flexibility so that it can be bent and attached to the curved surface of the sensing object.

In addition, a plurality of sensing holes 211 may be formed in the base pad 210 so that the first and second conductive lines 221 and 222 are partially exposed in order to sense the chemical exposure.

The sensing hole 211 is a passage through which a leaked chemical substance is brought into contact with the first and second conductive wires 221 and 222 , and a chemical substance is introduced by a capillary phenomenon and comes into contact with the first and second conductive wires 221 and 222 . . Here, the sensing hole 211 may have various shapes, such as a circle, an ellipse, and a polygon.

The sensing hole 211 may be formed on only one surface of the base pad 210 or may be formed on both surfaces of the base pad 210 . When formed on both sides, the sensing hole 211a on one side and the sensing hole 211b on the back may be arranged to coincide in the vertical direction, and may be alternately arranged in consideration of the thickness and strength of the base pad 210 . may be

The 1-4 first conductive wires 221 to 224 may be made of any one selected from gold, silver, stainless, copper, chromium, tungsten, molybdenum, nickel-copper alloy, and tungsten-molybdenum alloy, and the cross-section may be circular or It can be pad type. Here, any one of the first and fourth conductive wires 221 to 224 may be replaced with a resistance wire.

According to this configuration, water is applied to the first and second conductive wires 221 and 222 through the sensing hole 211 in a state in which a voltage is alternately applied to the first conductive wire 221 and the second conductive wire 222 every predetermined period. , a chemical solution, and other physical properties (conductors) come into contact with each other to form a closed circuit due to leakage between the first conductive wire 221 and the second conductive wire 222 .

The resistance value and voltage vary depending on the location of the leak. At this time, when a voltage is applied, a closed circuit is formed, and the resulting resistance value is transmitted through the first conductive line 221 and the second conductive line 222 through the leak detection module 300. is sent to

When a voltage is applied in this way, the ionization of moisture contained in the leak is prevented, so that the resistance value at the location where the leak is generated does not change and a constant resistance value is obtained. And, since the leak detection module 300 acquires a resistance value and a voltage value through a closed circuit, it is possible to detect a leak occurrence position.

In other words, since the leak detection module 300 already knows the length of the resistance line by the stored data, it is possible to derive a more accurate position by comparing the obtained resistance value and the voltage value. Accordingly, the resistance value and the voltage value are received from the leak detection module 300 to calculate the distance according to the resistance value and the voltage value, and the leak detection module 300 compares the calculated value with a preset value and the calculated value If this is large, it is determined as a leak, and a detected value is output through the touch monitor 400 and a warning sound is sounded through a speaker (or a warning lamp) so that the operator can recognize the leak situation.

Next, the leak detection sensor 200 of the second embodiment is a film-type sensor, and as shown in FIG. 4 , the base film 230 made of an insulating and chemical resistance material and the base film 230 are arranged side by side at a predetermined distance on one surface of the base film The four 1-4 conductive wires 241 to 244 that are printed so as to be printed, and the sensing hole 251 that is coated and printed on the 1-4 conductive wires and exposes a part of the first and second conductive wires are formed.

Here, the base film 230 may be any one selected from insulating and chemical resistant materials, for example, PET, PVC, PU, PE, PP, PI, PC, PMMA, ABS, rubber resin, silicone, and Teflon.

The first to fourth conductive wires 241 to 244 provided on the base film 230 may have various shapes, such as a straight shape, an uneven shape, a gear shape, and a wave shape.

The first to fourth conductive wires 241 to 244 are conductive raw materials such as Ag, Cu, Al, black carbon, graphite, carbon nanotube particles, graphene nanoplates, nichrome, aluminum-black carbon mixture, and an acidic material; It can be printed as a conductive paste or conductive ink composed of a polymer resin that absorbs and chemically reacts or dissolves well in alkaline substances, local substances and non-polar substances, and two or more identical conductive wires or different conductive wires can be formed.

In contrast, the first and second conductive wires 241,242 are printed on the base film 230, while the third and fourth conductive wires 243,244 are Au to check the sensor length measurement, power connection state, and disconnection state. , Ag, Al, and a metal thin film made of stainless steel can be configured to be thermally laminated.

On the other hand, for the conductive paste and the conductive ink, a polymer resin should be carefully selected in consideration of the chemical properties. In general, polymeric resins that are well soluble in acidic, basic, organic and oily chemicals are aminoalkyl methacrylate copolymer, polysiloxane derivatives, polyphenolic modified resin, polyphenol (resol type), Polystyrene, polybudene, polyisobudene, CDR (An ultrahigh molecular weight alpha-olefin copolymer), Hydrogenated Polycyclopentadiene, polyvinylpyridine, Poly(dodecylacrylate), FLO (Chem Link, Petroleum Inc.), Poly(2-ethylhexyl) acrylate) and mixtures thereof.

Methyl ethyl ketone, propylene glycol methyl ether acetate, ethylene glycol n-butyl ether acetate (EGBEA), dipropylene glycol monomethyl ether acetate (DPMA), diethylene glycol methyl ethyl ether (MEDG), propylene glycol diacetate (PGDA), It is selected from dipropylene glycol monomethyl ether and diethylene glycol monoethyl ether (Carbitol), butyl carbitol acetate (BCA), butyl carbitol (BC), texanol (Texanol), and mixtures thereof. To avoid contact between the conductive wire and water, a water repellent must be used. As a representative water repellent, polymethylsilsesquioxane, wax, acrylic urethane resin, acrylic silicone resin, fluororesin, etc. may be used. And leveling agents, dispersants, UV stabilizers, and antioxidants are to use commercially used products.

The protective layer 250 serves to protect the 1-4 conductive wires 241 to 244 from chemicals and scratches and to prevent discoloration due to ultraviolet rays. The protective layer 250 is a composition composed of a UV stabilizer and a polymer resin, and may be formed by coating the upper portion of the 1-4 conductive wires with a thickness of 1um to 30um.

The detection holes 251 are formed in the protective layer 250 to provide passages for chemical substances to flow into the first and second conductive lines 241,242, and the detection holes 251 are spaced 1 at regular intervals. A line or two or more lines may be formed in parallel, and may be formed in a uniform pattern such as a circle, an ellipse, or a straight line.

The components of the above-mentioned protective layer can solve water repellency, solubility in chemicals, non-oxidation of conductive materials, etc., so it can exhibit superior performance compared to existing leak detection sensors.

Since the detection process of the leak detection sensor of the second embodiment is substantially the same as that of the leak detection sensor of the first embodiment, a detailed description thereof will be omitted.

The leak detection module 300 receives the detected value from the leak detection sensor 200 of the first and second embodiments in real time to determine whether there is a leak, and transmits the determination result to the touch monitor 400 . do Several such leak detection modules 300 may be connected to one touch monitor 400 in a multi-type. Accordingly, it is possible to detect a leak at the same time in several places, and it is possible to integrate and manage it in one touch monitor 400 .

As shown in FIGS. 5 to 7 , the leak detection module 300 may be largely composed of a housing 310 and internal parts installed inside the housing.

The internal component is connected to the leak detection sensor 200, and when a chemical substance is leaked, it detects a change in the decomposition voltage in the first and second conductive lines of the leak detection sensor to determine whether the chemical substance is leaked. With the decomposition voltage detection unit 320 for detecting the leak detection sensor 200 and connected to the leak detection sensor 200, when a chemical substance leaks, detects a change in resistance in the first and second conductive wires to detect a chemical leak a resistance sensing unit 330, and a switching unit 340 for selectively controlling either one of the decomposition voltage sensing unit and the resistance sensing unit to operate, or a switching unit 340 for selectively controlling both the decomposition voltage sensing unit and the resistance sensing unit to operate; The voltage sensing unit, the resistance sensing unit, and the control unit 350 for controlling the switching unit may be configured.

Here, the control unit 350, as shown in FIG. 6, the storage unit 351 in which the set values for the decomposition voltage value and the resistance value are stored, and the set value stored in the storage unit and the detected value sent from the leak detection sensor. A determination unit 352 that compares and determines whether a leak occurs, and the result value determined by the determination unit is converted into numerical data and transmitted to the touch monitor 400, and also receives a newly set setting value from the touch monitor. It may be composed of a transceiver 353 for storing in the storage unit.

In addition, in the housing 310 of the leak detection module 300, as shown in FIG. 7, a connection terminal 311 for connecting the leak detection sensor 200, a communication connection terminal 312, a power connection terminal 313 and A reset button connection terminal 314 may be configured. In particular, it is important that the 16-channel IP address switching circuit is basically configured so that 16 modules can be set and changed with a touch monitor or PC.

In addition, a reset button 360 may be provided on the housing 310 of the leak detection module 300 . The reset button 360 is to prevent damage to the leak detection sensor 200 .

In addition, in the housing 310 of the leak detection module 300, when the measured value is greater than the set value stored in the control unit 340, it is determined as a leak, and a speaker 370 that sounds a warning sound (or warning light) to the user. more can be installed. Therefore, it is possible to enable the operator to immediately recognize the leak situation.

In addition, the leak detection module 300 is the current change and voltage change value detected by the decomposition voltage detection unit 310 is greater than or equal to the set value, or the resistance and voltage change value detected by the resistance detection unit 320 is set When the value is greater than the value, it may further include a power cutoff unit for cutting off the power of the leak detection module.

When a high voltage of 220V is supplied when detecting a chemical by the decomposition voltage detection unit 310, the leak detection module 300 controls the current and voltage control unit, which is a subordinate element of the leak detection module, to output below DC 24V, , In addition, the current and voltage amplification part, which is a dependent element, adjusts the resistance value in the cyclic variable resistance control unit so that the decomposition voltage value (6V or less) of the chemical contacted to the leak detection sensor is adjusted according to the strength of the current flowing through the leak detection sensor. The chemical substance generates bubbles at the same time as the oxidation-reduction reaction. Here, it is preferable to set the + electrode and the - electrode to be changed every few seconds so that the conductive line of the leak detection sensor 200 is not damaged by the decomposition voltage.

In addition, when a chemical substance is detected by the resistance sensing unit 320 , when 220V of power is supplied, the voltage and current controller converts it to DC 24V, and the current and voltage to the resistance and voltage controller, which are dependent elements of the leak detection module 300 , (5V or less) is applied to the leak detection sensor 200 .

Then, in consideration of the specific resistance of the leaking chemical, the resistance change of the conductive wire varies according to the amount and type of the chemical in contact with the leak detection sensor 200, so it is adjusted with a cyclic variable resistance control unit, which is a dependent element, and connected The chemical substance in contact with the leak detection sensor 200 is sensed by comparing the resistance value of the entire conductive wire with the resistance value of the chemical substance in contact and set-up by the resistance change rate setting unit within 1 to 30%.

In addition, the leak detection module 300 operates by circulating the decomposition voltage method and the resistance change detection method by the time switch circuit provided therein, as well as the power connection state of the leak detection sensor 200, the disconnection state, the sensor's You can check the length measurement, the specific resistance measurement of the sensor, and the leak detection status.

The touch monitor 400 outputs the result of whether or not the leak is transmitted from the leak detection module while being connected to the leak detection module 300, and outputs the changed contents by inputting and changing the detection material, setting contents and setting conditions It has an output unit and a transmission unit for transmitting change data to the leak detection module 300 .

For example, the touch monitor 400 may display the detection line length, measurement line disconnection information, specific line short information, chemical detection, water detection, and other material detection, and the like, line length resistance value, detection upper/lower limit, The presence/absence of detection alarm can also be displayed, and a chemical substance detection function of a complex measurement method, a detection alarm function, a detection result display function, etc. can also be displayed.

In addition to this, the specific resistance value of the leak detection sensor, the sensor length, the power connection state, the disconnection of the conductive wire, etc. may be displayed.

As described above, the touch monitor 400 can control all of the leak detection modules with one touch monitor when a plurality of (specifically, 16) leak detection modules 300 are connected in multiple channels.

The conventional multi-channel leak detection module is configured to operate several systems on one PCB, but the multi-channel leak detection system of the present invention connects a multi-channel time switching connection terminal to a single module and connects several micro It is a multi-channel leak detection system that operates while moving and circulating power to each leak detection sensor within seconds (μs) to several milliseconds (ms). Most importantly, when one touch monitor and 16 leak detection modules are connected, each leak detection module with built-in IP address circuit is individually assigned a different IP address to set and control a single touch monitor. The detection range can be input and changed.

In the present invention, in detecting a leaked chemical, the resistance measurement detection function and the decomposition voltage measurement detection function can be used independently or in combination in a touch monitor that sets detailed contents for detecting a leaked chemical with one module. It is possible to detect leaks in the entire chemical area, from high to low ionization tendency materials, including water.

Although the above-described embodiment has been described with respect to a preferred embodiment of the present invention, the present invention is not limited thereto, and it is specified that it can be changed and implemented in various forms without departing from the technical spirit of the present invention.
