Description

Technical Field

[0001] The utility model relates to the field of gas monitoring, and particularly relates to a gas multi-dimensional data collector. Background Technique

[0002] Gas pressure regulating cabinets and pressure regulating wells are both important devices used in gas systems to ensure that the gas pressure is within a safe and stable range. Gas pressure regulating cabinets are mainly used to regulate and stabilize the gas pressure to ensure that the gas can be delivered to the user end at an appropriate pressure. The pressure regulating well is used to regulate the gas pressure in the underground gas pipeline to ensure that the gas is within a safe range before entering the user pipeline. Both of these devices are indispensable components of the gas system, which helps to ensure the safe and stable supply of gas and meet the needs of different users.

[0003] During the use process, when the pressure regulating cabinet or the pressure regulating well has abnormal working problems, such as abnormal pressure in the gas pipeline, gas leakage, abnormal gas flow, etc., it is not easy to be detected. The problems of the pressure regulating cabinet or the pressure regulating well are mainly discovered through manual inspection to find the above problems. However, manual inspection cannot be carried out all the time. Manual inspection cannot detect problems in a timely manner, cannot conduct a full range of inspections and long-term monitoring.

[0004] To solve the above problems, data collectors have emerged on the market. The data collector is installed in the pressure regulating cabinet or the pressure regulating well. The relevant working conditions in the pressure regulating cabinet or the pressure regulating well are monitored in real time through the data collector. When an abnormality occurs, the sensor device of the data collector sends the detected data to the control unit. The control unit processes the received information and then transmits it to the communication module, and reports it to the server through the communication module. The staff can remotely access the server to know the working status of the pressure regulating cabinet or the pressure regulating well. For example, the utility model patent with the authorization announcement number CN216143572U discloses that a data collector is arranged in the pressure regulating box body. By adding a data collector, the operation safety of the gas pressure regulating box is improved, faults are eliminated, losses are prevented, the maintenance cost of the pressure regulating box equipment is reduced, and a large amount of manual inspection work is saved, thus saving the manpower and material resources cost caused by inspection.

[0005] However, the current data collector has relatively single detection functions and can only detect relevant indicators of gas (such as gas pressure, temperature, and whether there is leakage), and does not have the function of detecting the water level in the pressure regulating cabinet or the pressure regulating well. The pressure regulating cabinet or the pressure regulating well is set outdoors. After rain, if the accumulated water in the pressure regulating cabinet or the pressure regulating well cannot be drained in time, it is easy to cause the water level in the pressure regulating cabinet or the pressure regulating well to rise, thereby soaking the relevant pipelines and equipment in the pressure regulating cabinet or the pressure regulating well, affecting the normal operation of the relevant gas pipelines and equipment. However, the relevant staff are unaware of this and cannot arrive at the scene in time to drain and dredge. Utility Model Content

[0006] The present utility model aims to provide a gas multi-dimensional data collector to monitor the water level in the pressure regulating cabinet or the pressure regulating well.

[0007] To achieve the above object, the present utility model adopts the following technical solution: A gas multi-dimensional data collector includes a housing. A control unit and a communication module are arranged inside the housing. The communication module is electrically connected to the control unit. The communication module includes an antenna located on the housing. The bottom of the housing is connected with a water level switch electrically connected to the control unit, and the water level switch is arranged vertically.

[0008] The principle and advantages of this solution are as follows: The gas multi-dimensional data collector in this application is used to monitor the working environment or relevant working parameters and data in the pressure regulating cabinet or the pressure regulating well. Since the data collector in the prior art also has a control unit and a communication module, the control unit and the communication module in the data collector in this application are prior art. The improvement of the data collector in this application lies in that a water level switch is arranged on the data collector. The water level switch is a sensor device for monitoring the liquid level, and is used to monitor the liquid level height of the accumulated water in the pressure regulating cabinet or the pressure regulating well. The water level switch transmits the monitored liquid level information to the control unit, and the liquid level information is then transmitted to the network server through the communication module. The staff can remotely access the server through a computer, so as to be able to timely know the liquid level height of the accumulated water in the pressure regulating cabinet or the pressure regulating well. When the liquid level height is abnormal, the staff will reach the corresponding pressure regulating cabinet or pressure regulating well to perform drainage operations.

[0009] Thus, through the solution of this application, the real-time monitoring of the liquid level height of the accumulated water in the pressure regulating cabinet or the pressure regulating well is realized. When the liquid level height is abnormal, the staff can timely know and arrive at the scene to perform drainage operations, so as to be able to reduce the soaking of the relevant pipelines and equipment in the pressure regulating cabinet or the pressure regulating well by the accumulated water and ensure the normal operation of the pipelines and equipment in the pressure regulating cabinet or the pressure regulating well.

[0010] Preferably, as an improvement, the water level switch is a float type liquid level switch.

The pressure relief valve is used to adjust the internal pressure of the gas multi-dimensional data collector, avoiding the inconsistency between the internal pressure of the gas multi-dimensional data collector and the external atmospheric pressure. After the internal pressure of the gas multi-dimensional data collector is adjusted, the detection of the pipeline gas pressure in the pressure regulating cabinet or the pressure regulating well by the gas multi-dimensional data collector will be more accurate.

[0012] Preferably, as an improvement, a Bluetooth module is provided on the housing. The setting of the Bluetooth module enables this multi-dimensional data collector to have the function of Bluetooth connection. In this way, for the on-site inspection staff, the staff can use a handheld terminal to connect to this gas multi-dimensional data collector through Bluetooth connection. The gas multi-dimensional data collector transmits data and other information to the handheld terminal through Bluetooth transmission, and the handheld terminal displays the data collected by the gas multi-dimensional data collector, so as to facilitate viewing the equipment operation logs and operation parameters in the pressure regulating cabinet or the pressure regulating well.

[0013] Preferably, as an improvement, a push-button switch for controlling the Bluetooth module is provided on the housing. Through the push-button switch, the opening and closing of the Bluetooth module are realized.

[0014] Preferably, as an improvement, a positioning module is provided on the housing, and the positioning module is electrically connected to the control unit. The positioning module is used to locate the position of this gas multi-dimensional data collector. In this way, when the gas multi-dimensional data collector detects abnormal operation of the equipment in the pressure regulating well or the pressure regulating cabinet, while uploading the abnormal data to the server, it can also upload the geographical location, so as to facilitate remote personnel to know the location of the pressure regulating well or the pressure regulating cabinet.

[0015] Preferably, as an improvement, a laser methane sensor is provided on the housing, and the laser methane sensor is electrically connected to the control unit. The laser methane sensor is used to detect the methane concentration in the enclosed space in the pressure regulating cabinet or the pressure regulating well, so as to detect whether there is gas leakage in the pressure regulating cabinet or the pressure regulating well.

[0016] Preferably, as an improvement, a pressure sensor probe is provided on the housing, and the pressure sensor probe is electrically connected to the control unit. The pressure sensor probe is used to connect to the gas pipeline in the pressure regulating cabinet or the pressure regulating well, so as to detect the gas pressure of the gas pipeline in the pressure regulating cabinet or the pressure regulating well.

[0017] Preferably, as an improvement, the number of pressure sensor probes is two, and the two pressure sensor probes are a medium-pressure pressure sensor probe and a low-pressure pressure sensor probe respectively. The medium-pressure pressure sensor probe and the low-pressure pressure sensor probe are used to connect to the high-pressure end and the low-pressure end of the gas pipeline respectively.

[0018] Preferably, as an improvement, the housing is provided with an RS485 interface. RS485 is a serial communication interface standard. The RS485 interface of this gas multi-dimensional data collector is mainly connected to the RS485 interface of the flow meter in the gas pressure regulating cabinet or the pressure regulating well, and the gas multi-dimensional data collector reads the flow data of the flow meter through this interface. The transmission method using the RS485 interface has the characteristic of long transmission distance.

[0025] The following is a further detailed description through specific embodiments:

[0026] The reference numerals in the attached drawings of the specification include: screw 1, upper cover 2, main housing 3, lower cover 4, pressure relief valve 6, push button switch 7, Bluetooth module 8, antenna 9, communication module 10, laser methane sensor 11, RS485 interface 12, displacement switch 13, float level switch 14, pressure sensor probe 15, fixing block 16, sliding block 17, tightening bolt 18, mounting seat 19.

[0027] Embodiment 1

[0028] Basically as shown in the attached Figures 1-4 figures: A gas multi-dimensional data collector includes a housing, and the housing is composed of an upper cover 2, a lower cover 4 and a main housing 3. The upper cover 2 and the lower cover 4 are respectively located on both sides of the main housing 3, and the upper cover 2 and the lower cover 4 are both fixedly connected to the main housing 3 through screws 1.

[0029] The interior of the housing in this embodiment is provided with a chamber. Inside the housing, there are a battery, a control unit, and a communication module 10 that powers the entire instrument. The communication module 10 is electrically connected to the control unit. The communication module 10 includes an antenna 9 located on the housing. In this embodiment, the control unit can specifically adopt a single-chip microcomputer, and the models of the single-chip microcomputer are, for example, Arduino Uno, STM32F103, STM32F407, ATmega2560, etc. Its function is to receive the original signals detected by the sensor components (such as a water level switch), and convert the signals into a suitable format that can be transmitted, so that the communication module can transmit to the server in a suitable signal format. The communication module 10 in this embodiment is a DTU (Data Transfer Unit), and its function is to transmit data to a remote server or cloud platform through a mobile network (such as GSM, GPRS, LTE). The setting of the antenna 9 is used to receive and send wireless signals, enhancing the intensity of signal reception and transmission. In this embodiment, the control unit, the communication module, and the control unit receive the signals from the sensor components, convert them into a suitable format that can be transmitted, so that the communication module can transmit to the server in a suitable signal format, all of which belong to the prior art and will not be elaborated here.

[0030] The housing in this embodiment is provided with a positioning module, and the positioning module is electrically connected to the control unit. The positioning module has a GPS positioning function, which is mainly realized through a GPS chip. The positioning module transmits the positioning information to the control unit, and the control unit then uploads the position of the surge tank or surge chamber to the network server through the communication module 10.

[0031] The bottom of the housing in this embodiment is connected to a water level switch electrically connected to the control unit. The water level switch is used to detect the water level height. There are various types of water level switches. The water level switch in this embodiment is a float level switch 14, and the float level switch 14 is arranged vertically. The float level switch 14 is a component for monitoring liquids. By installing the gas multi-dimensional data collector in this embodiment in the surge chamber or surge tank, the float level switch 14 monitors the liquid level height of the accumulated water on the ground in the surge chamber or surge tank. The float level switch 14 transmits the liquid level information to the control unit, the control unit processes the liquid level information, and the processed information is transmitted to the communication module 10. The communication module 10 transmits the liquid level information to the network server, and the staff can remotely access the server through a computer, so as to be able to timely know the liquid level height of the accumulated water in the surge chamber or surge tank. When the liquid level height is abnormal (for example, the liquid level reaches the warning water level), the staff then arrives at the corresponding surge chamber or surge tank to check and perform drainage and dredging operations.

[0032] In addition, in some embodiments, a pressure sensor probe 15 is provided on the housing of this embodiment, and the pressure sensor probe 15 is electrically connected to the control unit. The number of pressure sensor probes 15 is two, and the two pressure sensor probes 15 are a medium-pressure sensor probe and a low-pressure sensor probe respectively. The gas pressure that the medium-pressure sensor probe can detect is greater than the gas pressure that the low-pressure sensor probe can detect. The medium-pressure sensor probe in this embodiment is used to detect the high-pressure end of the gas pipeline in the pressure regulating cabinet or the pressure regulating well, so as to detect the high-pressure gas, and the low-pressure sensor probe is used to connect to the low-pressure end of the gas pipeline, so as to detect the low-pressure gas. In this way, the medium-pressure sensor probe and the low-pressure sensor probe respectively detect whether the gas pressures at the high-pressure end and the low-pressure end of the gas pipeline are normal. If not, the pressure sensor probe 15 transmits the pressure information of the gas pipeline to the control unit, and the control unit processes the information and transmits it to the server through the communication module 10. The staff can monitor the pressure abnormality by remotely accessing the server.

[0033] In addition, in some embodiments, a pressure relief valve 6 is provided on the housing. After the multi-dimensional data collector is manufactured, it will be transported to different sites for use. Since the atmospheric pressures at the manufacturing site and the use site are different, if the multi-dimensional data collector is directly installed in the pressure regulating cabinet or the pressure regulating well for gas pressure detection, due to the inconsistent pressure inside and outside the multi-dimensional data collector, the detection will be inaccurate. At this time, before installing the multi-dimensional data collector, by opening the pressure relief valve 6, the inside and outside of the gas multi-dimensional data collector are connected, so that the pressure inside the gas multi-dimensional data collector is the same as the local external pressure, realizing the adjustment of the pressure inside the gas multi-dimensional data collector. In this way, after the pressure inside the gas multi-dimensional data collector is adjusted, the detection of the pipeline gas pressure in the pressure regulating cabinet or the pressure regulating well by the gas multi-dimensional data collector will be more accurate.

[0034] In addition, in some embodiments, a laser methane sensor 11 is provided on the housing, and the laser methane sensor 11 is electrically connected to the control unit. The laser methane sensor 11 is used to detect the methane concentration in the enclosed space in the pressure regulating cabinet or the pressure regulating well, so as to detect whether there is gas leakage in the pressure regulating cabinet or the pressure regulating well. When gas leakage occurs, the laser methane sensor 11 transmits the detected information to the control unit, and the control unit processes the information and then transmits it to the server through the communication module 10 for the staff to remotely access.

[0035] In addition, in some embodiments, an RS485 interface 12 is provided on the housing. The RS485 interface 12 of this gas multi-dimensional data collector is mainly connected to the RS485 interface of the flow meter in the gas pressure regulating cabinet or the pressure regulating well. The gas multi-dimensional data collector reads the flow data of the flow meter through this RS485 interface 12. After the flow data is read, it is transmitted to the control unit. The control unit processes the read data and then transmits it to the server through the communication module 10 for remote access by the staff.

[0036] In addition, in some embodiments, a Bluetooth module 8 is provided on the housing. A button switch 7 for controlling whether the Bluetooth module 8 is turned on is provided on the housing. The setting of the Bluetooth module 8 enables this gas multi-dimensional data collector to have the function of Bluetooth data transmission. In this way, for the on-site inspection staff, the staff can use a handheld terminal (such as a mobile phone) to connect to this gas multi-dimensional data collector through Bluetooth connection. The gas multi-dimensional data collector transmits the collected data and other information to the handheld terminal through Bluetooth transmission. The handheld terminal displays the data collected by the gas multi-dimensional data collector, so as to facilitate viewing the equipment operation logs and operation parameters in the pressure regulating cabinet or the pressure regulating well.

[0037] In addition, in some embodiments, a displacement switch 13 is provided on the housing, and the displacement switch 13 is electrically connected to the control unit. The displacement switch 13 is used to detect whether the manhole cover of the gas pressure regulating well is opened or whether the cabinet door of the gas pressure regulating cabinet is opened. When the manhole cover of the pressure regulating well is opened or the cabinet door of the gas pressure regulating cabinet is opened, the control unit uploads this message to the server through the communication module 10, and the staff can know in time and immediately arrive at the scene to close the manhole cover or the cabinet door.

[0038] The multi-dimensional data collector in this embodiment realizes the detection of multiple data of the equipment in the pressure regulating cabinet or the pressure regulating well. The monitored data can be transmitted to the server for remote access by the staff using a computer. If an abnormality occurs, the staff can arrive at the scene in time for maintenance.

[0039] Embodiment 2

[0040] The bottom of the housing of this embodiment is equipped with a telescopic unit, combined with Figure 5As shown in the figure, the telescopic unit includes a fixed block 16 and a sliding block 17. The interior of the fixed block 16 is provided with a vertical sliding cavity. The bottom of the sliding cavity is provided with an opening. The sliding block 17 is inserted into the sliding cavity through the opening and is vertically slidably connected to the fixed block 16. A tightening bolt 18 is threadedly connected to the fixed block 16. The bottom of the sliding block 17 is provided with a mounting seat 19, and the mounting seat 19 is used for fixedly connecting the water level switch. For example, the side of the water level switch housing is fixed to the mounting seat 19 by screws or fixed by a clamp, etc. In this embodiment, by loosening the tightening bolt 18, the sliding block 17 can vertically slide on the fixed block 16. By tightening the tightening bolt 18, the fixation of the sliding block 17 and the fixed block 16 is achieved, and the sliding block 17 will not move on the fixed block 16.

[0041] In Embodiment 1, the water level switch is directly fixedly installed on the housing, but the vertical position of the water level switch cannot be adjusted. When installing the gas multi-dimensional data collector in different pressure regulating cabinets or wells, due to the differences in the sizes of different pressure regulating cabinets or wells, the installation position of the gas multi-dimensional data collector may be too high or too low due to the different depths of the pressure regulating cabinets or wells. In this way, the water level switch cannot normally monitor the accumulated water at the bottom of the pressure regulating cabinet or the bottom of the well. For this reason, in this embodiment, a telescopic unit is provided on the outside of the housing. The telescopic unit can be telescoped. When the gas multi-dimensional data collector is installed in different pressure regulating cabinets or wells, the sliding block 17 can be slid according to the actual situation to adjust the height of the water level switch (when the distance between the bottom of the multi-dimensional data collector and the ground is large, the telescopic unit is extended; when the distance between the bottom of the multi-dimensional data collector and the ground is small, the telescopic unit is shortened). After the length of the telescopic unit is adjusted, by tightening the tightening bolt 18, the fixation of the height of the water level switch is achieved. Thus, through this embodiment, when installing the gas multi-dimensional data collector, the height of the water level switch can be adjusted, so as to ensure that the water level switch can monitor the accumulated water at the bottom of cabinets or wells with different depths.

[0042] The above are only embodiments of the present invention. Well-known specific technical solutions and / or common knowledge such as characteristics are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
