Please refer to fig. 1, which is a flowchart illustrating a method for monitoring a liquid medicine leakage alarm according to an embodiment of the present invention. The liquid medicine leakage alarm monitoring method comprises part or all of the following steps.
S100: and acquiring a probe monitoring signal of the liquid level relay.
In this embodiment, the level relay has a plurality of probes, and each probe should have a function of acquiring a signal, that is, the probe introduces an external signal into the level relay. The signal that liquid level relay's probe gathered does probe monitor signal, probe monitor signal is used for the state change of sensing external environment, for example, liquid level relay's probe is located leakage prevention inslot, touches when the water level of the liquid medicine in leakage prevention inslot during liquid level relay's probe, liquid level relay's probe acquires corresponding probe monitor signal, is convenient for monitor the water level height in leakage prevention inslot.
S200: detecting whether the probe monitoring signal matches a preset signal.
In this embodiment, the preset signal is a signal corresponding to the liquid level relay when being triggered to alarm, that is, the preset signal is an alarm signal monitored by a probe of the liquid level relay, that is, when the potential of the probe of the liquid level relay reaches an alarm potential, the potential signal monitored by the probe of the liquid level relay. Like this, through setting up predetermine the electric potential that the signal corresponds, be convenient for adjust the liquid level height of liquid level relay's probe monitoring, make with probe monitoring signal with when predetermineeing the signal and comparing, through the signal matching condition between the two, confirm whether the liquid level of current liquid medicine reachs the warning liquid level to the time of the follow-up definite warning of being convenient for has ensured in time to send alarm signal.
S300: and when the probe monitoring signal is matched with the preset signal, controlling a normally open switch group of the liquid level relay to be closed so that the alarm platform sends an alarm signal to the monitoring system.
In this embodiment, probe monitoring signal monitors the liquid medicine liquid level of outside leakage, promptly the liquid level relay's probe is gathered the liquid level height of outside liquid medicine, promptly the probe monitoring signal is corresponding to the water level height of the liquid medicine of outside leakage, and preset signal is corresponding to the maximum value of the height of outside leakage liquid medicine, promptly preset signal and the outside maximum liquid level height of leaking liquid medicine corresponding. The probe monitoring signal is matched with the preset signal, and indicates that the liquid level height of the liquid medicine collected by the probe of the liquid level relay at present reaches the maximum liquid level height of the externally leaked liquid medicine, namely, the liquid level height of the leaked liquid medicine contacted by the probe of the liquid level relay reaches the safety alarm height of the liquid medicine leakage, namely, the liquid level height of the externally leaked liquid medicine reaches the allowed maximum leakage liquid level height. At this time, the volume of the externally leaked liquid medicine has reached the maximum volume, and if the leakage is continued, it causes a safety problem. In order to give an alarm for the current liquid medicine leakage in time, a contact signal is sent to a normally open switch group of the liquid level relay, so that the normally open switch group of the liquid level relay is closed, the alarm platform is triggered to send an alarm signal to a monitoring system, and for example, the alarm platform sends the alarm signal to a mobile phone with the monitoring system.
In one embodiment, the acquiring a probe monitoring signal of the liquid level relay includes: acquiring conducting signals of three probes of the liquid level relay; detecting whether the probe monitoring signal is matched with a preset signal or not, comprising: detecting whether the conducting signal is matched with the preset signal or not; when probe monitoring signal with when presetting signal matching, control liquid level relay's normally open switch group is closed, include: and when the conduction signal is matched with the preset signal, the normally open switch group is adjusted to be in a closed state. In this embodiment, liquid level relay acquires through three probes on it probe monitoring signal, three probes of liquid level relay gather as the liquid level height of contact point liquid medicine, wherein, through conduction condition between three probes of liquid level relay judges, promptly through detecting whether have the condition that the electric current switched on between three probes of liquid level relay, conduction signal is promptly current signal on each probe of liquid level relay. Because the liquid medicine is used as dielectric solution, the probe and the liquid medicine form a current loop under the condition that the probe is connected with voltage and immersed, so that current flows through the probe, and the structure is similar to a connection structure between the internal electrolyte of a lithium ion battery cell and a positive electrode and a negative electrode. And, preset the signal and simplify to this moment the current signal between three probes of liquid level relay, through to there is the judgement of no electric current between three probes of liquid level relay, be convenient for confirm the liquid level of outside leakage liquid medicine. The conducting signal is matched with the preset signal, and indicates that conducting current exists among the three probes of the liquid level relay, namely that current conducting signals exist among the three probes of the liquid level relay, namely that the three probes of the liquid level relay are soaked by externally leaked liquid medicine. Like this, under three probes of liquid level relay contacted the outside circumstances of leaking liquid medicine simultaneously liquid level relay's internal power supply was when the probe power supply, it has the electric current to flow through between three probes of liquid level relay, is convenient for confirm that outside leaks liquid medicine and has reached the maximum liquid level of leaking liquid medicine to be convenient for in time send alarm signal. Wherein, the height difference between three probes of liquid level relay, for example, three probes of liquid level relay all are different apart from the height that is equipped with the bottom of the anti-leakage groove that leaks liquid medicine, according to the actual safety requirement to liquid medicine leakage, adjusts the distance between probe and the bottom of anti-leakage groove, is convenient for correspond the adjustment to the security level that different liquid medicine leaked, realizes timely warning.
Further, the detecting whether the turn-on signal matches the preset signal further includes: and when the conducting signal is not matched with the preset signal, maintaining the normally open switch group in an off state. In this embodiment, the conducting signal is not matched with the preset signal, which indicates that no conducting current exists between the three probes of the liquid level relay, that is, it indicates that no current conducting signal exists between the three probes of the liquid level relay, that is, the external leaked liquid medicine does not infiltrate the three probes of the liquid level relay at the same time. Therefore, the volume of the leaked liquid medicine is below the safety limit, the leaked liquid medicine is not enough to cause safety problems, the normally open switch group is maintained to be in an off state in order to not influence normal production, the normally open switch group is continuously kept in the normally open state before, and the alarm platform is not triggered to send an alarm signal.
In one embodiment, the acquiring a probe monitoring signal of the liquid level relay includes: and respectively acquiring the potential of a first probe, the potential of a second probe and the potential of a third probe of the liquid level relay. In this embodiment, because be the monitoring and the warning of liquid medicine leakage, the volume of the liquid medicine of leaking can not be too big, in time sends alarm signal when the liquid medicine leakage takes place usually to reduce the production safety problem that liquid medicine leakage brought. And three probes of the liquid level relay are used for monitoring the liquid level of leaked liquid medicine, and when the leaked liquid medicine leaks, the three probes of the liquid level relay are sequentially infiltrated by the leaked liquid medicine along with the increase of the volume of the leaked liquid medicine, so that the potential of the first probe, the potential of the second probe and the potential of the third probe of the liquid level relay are changed. Like this, at the initial stage that liquid medicine took place to leak, the volume of leaking liquid medicine is less, makes liquid medicine volume between three probes of liquid level relay is less, thereby makes equivalent resistance between three probes of liquid level relay is zero, and then makes and contact simultaneously leaking liquid medicine during three probes of liquid level relay, three probe short circuits of liquid level relay, promptly the electric potential of three probes of liquid level relay is the same, for example, detect whether probe monitoring signal matches with preset signal, include: and detecting whether the potential of the first probe, the potential of the second probe and the potential of the third probe are the same. The potential of the three probes of the liquid level relay is convenient to determine whether the liquid level of the leaked liquid medicine reaches the alarm liquid level.
Further, when the probe monitoring signal matches with the preset signal, the normally open switch group of the liquid level relay is controlled to be closed, including: and when the electric potential of the first probe is the same as the electric potential of the second probe and the electric potential of the third probe, closing the normally open switch group of the liquid level relay. The potential of the first probe is the same as that of the second probe and that of the third probe, which indicates that the three probes of the liquid level relay are short-circuited, i.e. indicates that the three probes of the liquid level relay are connected with each other, i.e. indicates that leaked liquid medicine simultaneously contacts the three probes of the liquid level relay. Therefore, when the probe at the highest position in the three probes of the liquid level relay contacts leaked liquid medicine, the liquid level of the leaked liquid medicine reaches the safety alarm liquid level, and the normally open switch group of the liquid level relay is controlled to be closed so as to trigger the alarm platform to send an alarm signal.
Still further, detecting whether the probe monitoring signal matches a preset signal, then further comprising: and when the potential of the first probe is greater than at least one of the potential of the second probe and the potential of the third probe, the normally-open switch group of the liquid level relay is disconnected. In this embodiment, the three probes of the liquid level relay have initial voltages, that is, before the leaked liquid medicine contacts the probes, the voltages on the probes are different, for example, the voltage of the first probe is greater than that of the second probe, the voltage of the second probe is greater than that of the third probe, and the distance between the first probe and the bottom of the leakage-proof tank is the largest, the distance between the third probe and the bottom of the leakage-proof tank is the smallest, and the distance between the second probe and the bottom of the leakage-proof tank is between the largest distance and the smallest distance, that is, the heights of the first probe, the second probe and the third probe are sequentially reduced, so as to form different liquid level monitoring gradients. The potential of the first probe is greater than at least one of the potential of the second probe and the potential of the third probe, indicating that the potential of the first probe is changed, i.e., indicating that there is a gap between the first probe and the leaking reagent, i.e., indicating that the leaking reagent is not in contact with the first probe. Thus, the voltage of the first probe is still at a maximum, so that the detected level of leaking liquid medicine is still below the first probe, so that the detected level of leaking liquid medicine is at a safe level.
Still further, the normally open switch set that opens the level relay when the potential of the first probe is greater than at least one of the potential of the second probe and the potential of the third probe includes: and when the potential of the first probe is greater than that of the second probe and the potential of the second probe is equal to that of the third probe, maintaining the normally open switch group of the liquid level relay in an off state. In this embodiment, the volume of leaking liquid medicine is gradually increased, that is, the liquid level of leaking liquid medicine gradually rises, the potential of the second probe is equal to the potential of the third probe, which indicates that the leaking liquid medicine infiltrates the second probe and the third probe simultaneously, that is, indicates that the leaking liquid medicine simultaneously contacts the second probe and the third probe, but at this time, the first probe does not contact the leaking liquid medicine, so that the liquid level detected by the liquid level relay is still below the safety alarm liquid level, and no alarm signal needs to be sent.
Further, when the potential of the first probe is greater than at least one of the potential of the second probe and the potential of the third probe, the normally open switch group of the liquid level relay is opened, and the method comprises the following steps: and when the potential of the second probe is equal to the potential of the third probe and the potential of the second probe is reduced to be less than the potential of the first probe, the normally open switch group of the liquid level relay is adjusted to be in an off state from a normally closed state. In this embodiment, the volume of the leaked liquid medicine is gradually reduced, that is, the liquid level of the leaked liquid medicine is gradually decreased, the potential of the second probe is equal to the potential of the third probe, which indicates that the leaked liquid medicine contacts the second probe and the third probe, and the potential of the second probe is decreased to be less than the potential of the first probe, which indicates that the leaked liquid medicine is not in contact with the first probe, so that the liquid level of the leaked liquid medicine is decreased to be below the safety alarm liquid level. At the moment, leaked liquid medicine is cleared away, so that the leaked liquid medicine does not threaten the production safety, the normally open switch group of the liquid level relay is controlled to be adjusted from a normally closed state to an open state, and the alarm platform is not triggered to send an alarm signal any more.
It can be understood that liquid level relay's probe is used for contacting with liquid medicine, and in long-term contact process, for example, liquid level relay's third probe, contacts with leaking liquid medicine for a long time, liquid level relay's probe will react with some chemical composition in the leakage liquid medicine, is in easily the surface of liquid level relay's probe is formed with the complex, makes the surface of liquid level relay's probe is wrapped up by other non-conductive material, for example, the surface of liquid level relay's probe rusts, thereby makes the surface of liquid level relay's probe is oxidized, and then makes liquid level relay's probe's electric conductive property reduces, leads to liquid level relay's probe can't accurately detect and leaks liquid medicine, thereby leads to unable timely alarm signal that sends out.
In order to further improve the timeliness of sending the alarm signal, the method for acquiring the probe monitoring signal of the liquid level relay further comprises the following steps:
acquiring a radial detection image of a probe of the liquid level relay;
acquiring a thickness value of the probe according to the radial detection image;
comparing the thickness value with a preset thickness value to obtain the thickness feedback quantity of the probe;
and adjusting the output current of the probe according to the thickness feedback quantity of the probe so as to heat the probe.

In order to reduce the probability of rusting after the surface of the probe is corroded by the chemical liquid, please refer to fig. 3 and 5, the chemical liquid leakage alarm monitoring device 10 further includes a protection cup 300, the protection cup 300 is disposed in the leakage-proof box 100, at least a portion of the first probe 210 and at least a portion of the second probe 220 are contained in the protection cup 300, the protection cup 300 is provided with an introduction hole 310, a distance between the center of the introduction hole 310 and the bottom of the leakage-proof box 100 is greater than a minimum distance between the second probe 220 and the bottom of the leakage-proof box 100, and a distance between the center of the introduction hole 310 and the bottom of the leakage-proof box 100 is less than the minimum distance between the first probe 210 and the bottom of the leakage-proof box 100. In this embodiment, the protective cup 300 accommodates the first probe 210 and the second probe 220, so that the probability of the first probe 210 and the second probe 220 contacting with the liquid medicine is reduced, and the probability of corrosion and rusting of the first probe 210 and the second probe 220 is reduced.

The removal of the surface rust of the second probe 220 is the same as the first probe 210, and is not described herein again.
When no liquid medicine is in the protective cup 300, the cleaning plate 410 drops to the bottom of the protective cup 300, and when liquid medicine enters the protective cup 300, the cleaning plate 410 is pressed against the bottom of the protective cup 300, so that rust on the surface of each probe cannot be removed. In order to avoid the above situation, the position of the cleaning plate 410 is limited by the limiting plate 420, that is, the limiting plate 420 is located on one side of the cleaning plate 410 close to the bottom of the protection cup 300, so that the limiting plate 420 is located below the cleaning plate 410, when the liquid medicine in the protection cup 300 is removed, the buoyancy applied to the cleaning plate 410 disappears, the cleaning plate 410 moves towards the bottom of the protection cup 300, and the limiting plate 420 blocks the cleaning plate 410 from further descending, and limits the cleaning plate 410 to a position having a distance from the bottom of the protection cup 300, so that there are gaps between the cleaning plate 410 and the bottom and the inner wall of the protection cup 300, that is, the distance between the limiting plate 420 and the bottom of the protection cup 300 is greater than 0, and the distance between the cleaning plate 410 and the inner wall of the protection cup 300 is greater than 0.
