Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
As shown in fig. 1, the downward arrows indicate the direction of water flow from the inlet pipe 104. The air compressor remote monitoring system provided by the embodiment comprises a first water storage device, a liquid level float switch 102 and an alarm signal generator (not shown in the figure). Wherein,
the first water storage device is provided with a water inlet and a water outlet 103, wherein the size of the water inlet is larger than that of the water outlet 103, namely the water inlet amount of the water inlet is larger than the water outlet amount of the water outlet 103. As a simple and easy embodiment, the first water storage means is a funnel 101.
The liquid level float switch 102 is disposed in the first water storage device, according to the working principle of the liquid level float switch 102, when the liquid (usually water) in the container is at a certain height, the liquid level float switch 102 is closed (on), and when the liquid in the container is lower than the certain height, the liquid level float switch 102 is opened, in this embodiment, the two liquid position heights are respectively defined as an upper water level limit and a lower water level limit, that is, when the water level of the stored water in the first water storage device is higher than the set upper water level limit, the liquid level float switch 102 is closed, and when the water level of the stored water in the first water storage device is lower than the set lower water level limit, the liquid level float switch 102 is opened.
The alarm signal generator is used for sending out an alarm prompt signal when the liquid level float switch 102 is disconnected so as to prompt a worker to deal with related faults as soon as possible.
As another embodiment, the level float can also be put into the following operating modes: the level float switch 102 is open when the level of the accumulated water in the first accumulator is above the set upper level limit and the level float switch 102 is closed when the level of the accumulated water in the first accumulator is below the set lower level limit. For the working mode, the alarm signal generator is used for sending out an alarm prompt signal when the liquid level float switch 102 is closed so as to prompt a worker to deal with related faults as soon as possible.
As an embodiment, the level float switch 102 may be connected to the alarm signal generator through a signal transmission cable, and the on/off state signal of the level float switch 102 may be transmitted to the alarm signal generator through the signal transmission cable.
As another more preferred embodiment, a wireless signal transmitter is connected to the level float switch 102 and is used for sending an on-off state signal of the level float switch 102 to the alarm signal generator. And a wireless signal transmission mode is adopted, so that the cost and wiring difficulty of remote wiring are avoided. The wireless signal transmitter can be purchased directly from the market, and the cost is low. As a further more preferred implementation, the wireless signal transmitter employs wireless input/output (I/O) devices, and the signal transmission is implemented by using wireless I/O technology, for example, the DW-J10/11 wireless switching value acquisition input controller produced by Shenzhen, Daizong technologies, Inc., and the receiving module in the alarm signal generator can select the DW-J20/21 wireless switching value controller produced by Shenzhen, Daizong technologies, Inc.
The alarm prompting signal can be realized in various ways, for example, the most widely used mode is audible and visual alarm, namely, a loudspeaker is used for emitting alarm sound, and a signal lamp is used for emitting a light prompting signal, namely, in this case, the alarm signal generator comprises a wireless signal receiver, a loudspeaker and a signal indicator lamp. Of course, the alarm prompt signal may be an audible alarm or an optical signal alarm.
The audible and visual alarm requires the operator to be on site, so as another preferable implementation mode, the alarm prompt signal can be a short message or a telephone voice message, namely, the alarm signal generator sends a short message to a specified (preset) number in a short message cat or the like mode, or calls the specified number. The method has no limitation on the geographical position of the worker, and the reliability is stronger as long as the worker carries the mobile phone. The implementation of the alarm signal generator is prior art and will not be described in detail here.
In the air compressor machine remote monitering system that this embodiment provided, the water inlet of first water storage device communicates with outlet pipe 110 in air compressor machine cooling system 111, when the circulating water normally works, rivers continuously flow into air compressor machine cooling system 111's inlet tube 104, then flow from outlet pipe 110, pour into funnel 101, because the inflow of water inlet is greater than the water yield of delivery port 103, this moment excessive water volume overflows from funnel 101, liquid level float switch 102 installs on funnel 101, when funnel 101 liquid level is higher than the upper limit of water level of settlement, liquid level float switch 102 switches on, alarm signal generator detects that the circulating water normally pours into funnel 101. When the circulating water has a fault and the amount of the injected water is reduced, the injection flow in the hopper 101 is lower than the discharge flow, the liquid level of the hopper 101 gradually decreases, when the water level is reduced to a set lower limit of the water level, the liquid level float switch 102 is switched off, the alarm signal generator detects the fault of the circulating water and sends an alarm prompt signal to remind an operator to process the relevant fault as soon as possible.
Example 2
As shown in fig. 2, the downward arrow in the figure indicates the direction of water flow entering from the water inlet, and the rightward arrow indicates the direction of emergency water flow entering from the water pipe 107. Compared with the remote monitoring system provided in embodiment 1, the remote monitoring system provided in this embodiment further includes a liquid pressure sensor 105 disposed in the water inlet pipe 104, and is used for detecting the water pressure of the water inlet pipe 104 and sending the detected water pressure signal of the water inlet to the alarm signal generator through the wireless signal transmitter. When the water inlet pressure is higher than the set water pressure threshold value, the circulating water supply is normal, and the air compressor normally operates; when the water pressure of the inflow water is lower than the set water pressure threshold value, the circulating water is insufficient in supply, the air compressor is likely to break down, and the alarm signal generator sends out an alarm prompt signal to remind a worker to process in time. The detection of the water inlet pressure and the detection of the on-off state of the liquid level float switch 102 are two detection means, and the two detection means are used simultaneously, so that the reliability of the monitoring system can be further improved.
The purpose of monitoring the running state of the air compressor is to ensure the normal running of the air compressor, therefore, as a preferred embodiment, an emergency water source can be set, and the normal water is supplied when the water amount of the normal inlet water is insufficient, so that the normal supply of circulating water is ensured, the normal running of the air compressor is further ensured, and the fault-free running time of the air compressor is improved. Therefore, in this embodiment, the air compressor remote monitoring system further includes a second water storage device 106, the second water storage device 106 is communicated with the water inlet pipe 104 of the air compressor cooling system 111 through a water pipe 107, and an emergency valve is arranged in the water pipe 107; the second water storage device 106 is used for containing emergency water, and when the liquid pressure sensor 105 detects that the water inlet pressure is lower than a set water pressure threshold value, the emergency water is provided for the first water storage device. The emergency valve may be a common manual valve, and when the monitored water pressure of the inlet water is lower than the set water pressure threshold, the operator may manually open the valve to allow the emergency water to be injected into the air compressor cooling system 111 from the water pipe 107. The emergency valve is preferably a solenoid valve 108, and the solenoid valve 108 is directly controlled to be opened when the liquid pressure sensor 105 detects that the water pressure of the inlet water is lower than a set threshold value.
The monitored control system that this embodiment provided can ensure in time report to the police when water route circulation system breaks down, can also ensure even break down can not influence the air compressor machine and normally work yet.
The corresponding description in example 1 is for what is not mentioned in this example.
Example 3
The air compressor remote monitoring system provided in this embodiment is a further improvement on the basis of embodiment 2, and please refer to embodiment 2 for details not referred to in this embodiment. As shown in fig. 3, the water pipe 107 is communicated with the water inlet pipe 104, so when emergency water is injected into the water inlet pipe 104 from the water pipe 107, the emergency water may press the liquid pressure sensor 105, that is, the water inlet pressure detected by the liquid pressure sensor 105 is the water pressure of the water entering from the original water inlet pipe 104 (the water inlet pipe 104 before the emergency water is injected) and the water pipe 107 together, when the water pressure of the water entering together is lower than the set water pressure threshold, the liquid pressure sensor 105 controls the electromagnetic valve 108 to open, and the emergency water is injected into the first water storage device through the water pipe 107. That is, as long as the water inlet pressure detected by the liquid pressure sensor is lower than the set threshold, the electromagnetic valve 108 is controlled to be opened all the time to ensure that enough circulating water is available to enable the air compressor to work normally.
Since the water pressure detected by the liquid pressure sensor 105 includes both the water pressure of the water entering from the original water inlet pipe 104 and the water pressure of the emergency water entering from the water pipe 107 when the emergency valve is opened, the water pressure detected by the liquid pressure sensor may be higher than the set threshold, but actually, the water pressure of the water entering from the original water inlet pipe 104 is lower than the set threshold, that is, the original circulating water path has failed, and the detection result has an error. Therefore, as a more preferable embodiment, in this embodiment, as shown in fig. 3, a check valve 109 is disposed in the water inlet pipe 104, the check valve 109 is located below the liquid pressure sensor 105 (only for the direction shown in the drawing), the check valve 109 is used to limit that the emergency water in the water pipe 107 can only flow to the air compressor cooling system 111, that is, the emergency water in the water pipe 107 is limited to ram the liquid pressure sensor 105, at this time, the emergency water cannot flow to the position of the incoming water liquid pressure sensor 105, the incoming water pressure measured by the liquid pressure sensor 105 can only be the water pressure of the incoming water from the original water inlet pipe 104, and the incoming water pressure detected by the liquid pressure sensor 105 is lower than a set water pressure threshold, so the alarm signal generator will send an alarm prompt signal to prompt a worker to deal with the related fault as soon as possible. In addition, the emergency water in the limiting water pipe 107 can only flow to the air compressor cooling system 111, but cannot flow to the other direction of the water inlet pipe, so that the emergency water is taken as an emergency, and the emergency water is prevented from flowing out from the other direction of the water inlet pipe to cause waste.
The monitoring system provided by the embodiment can ensure that accurate detection results can be obtained under any condition, and can give an alarm in time when the original waterway system breaks down, so that the reliability of the monitoring system can be further improved.
Example 4
The air compressor remote monitoring system provided in this embodiment is a further improvement on the basis of embodiment 3, and please refer to embodiment 3 for details not referred to in this embodiment. In this embodiment, air compressor machine remote monitering system still includes gas pressure sensor for detect the gas pressure of air compressor machine gas outlet department, when gas pressure is higher than the setting value, the air compressor machine normally works, when gas pressure is less than the setting value, the air compressor machine probably breaks down. The gas pressure sensor is connected with the wireless signal transmitter, the wireless signal transmitter transmits a gas pressure signal acquired by the gas pressure sensor to the alarm signal generator, and the alarm signal generator sends an alarm prompt signal when the gas pressure is lower than a set value.
The fault of the water path circulation system is an important factor causing the air compressor to be incapable of normally operating, and if the air path system is in fault, or the air compressor is in mechanical or electrical fault, the air compressor is also caused to be incapable of normally operating. Monitoring system combines gas circuit system fault detection on the basis of water path circulation system fault detection in this embodiment, can all monitor because of the condition that the air compressor machine that water path circulation system trouble and gas circuit system trouble lead to can not normal operating at least, has further improved this monitoring system's reliability.
It should be noted that, in any of the above embodiments or implementations, the liquid pressure sensor 105 may be replaced by a liquid flow sensor, and the liquid flow sensor is used to detect the inflow water flow rate in the inflow pipe, so at this time, correspondingly, the liquid flow sensor is connected with a wireless signal transmitter, and sends a signal of the liquid flow sensor to an alarm signal generator through the wireless signal transmitter, the alarm signal generator sends the alarm prompt signal when the inflow water flow rate is lower than a set flow threshold, and the emergency valve is also opened when the inflow water flow rate is lower than the set flow threshold.
The wireless signal transmitters connected with the liquid level floater, the liquid pressure sensor and the liquid flow sensor can be the same device, namely the liquid level floater, the liquid pressure sensor and the liquid flow sensor are all connected with the same wireless signal transmitter; in another embodiment, the liquid level float, the liquid pressure sensor and the liquid flow sensor may be respectively connected with a wireless signal transmitter, which may result in increased cost.
In the above embodiments 2 to 4, the emergency valve may be controlled by the liquid level float or the liquid pressure sensor alone, and when the liquid level float detects that the water level of the water stored in the first water storage device is lower than the set lower water level limit, or when the liquid pressure sensor detects that the water pressure of the intake water is lower than the set water pressure threshold, the emergency valve is controlled to be opened; the emergency valve can also be controlled by the liquid level float and the liquid pressure sensor at the same time, and when any one of the liquid level float and the liquid pressure sensor gives an alarm, the emergency valve is controlled to be opened. In the embodiment in which the liquid pressure sensor is replaced by a liquid flow sensor, the emergency valve can accordingly be controlled by the level float or the liquid flow sensor alone or by both.
In the above embodiments 2-4, the second water storage device can select tap water as the emergency water source.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
