Detailed Description
The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
Fig. 1 is a schematic block diagram of a monitoring device according to an exemplary embodiment, the monitoring device being disposed at a construction site, as shown in fig. 1, and comprising: housing 1 and set up in a plurality of modules in housing 1, and a plurality of modules include: the power management module 10 is configured to obtain an external power signal and perform security processing on the external power signal, so as to provide the processed power signal to a plurality of modules, where the power management module 10 is provided with a plurality of power supply lines for power consumption situations of the plurality of modules; an image acquisition module 20, configured to acquire image information of each azimuth of the construction site; the data processing module 30 is configured to perform data processing on the image information acquired by the image acquisition module, so as to obtain corresponding image data; and the remote communication module 40 is used for uploading the image data processed by the data processing module to a background server, so that the background server displays the picture of the construction site in real time according to the image data and identifies the abnormal condition of the construction site.
For example, for the power management module 10, since the monitoring device of the embodiment of the present invention requires an external power supply, and the external power supply signal may have a considerable interference signal in consideration of the complex environment of the construction site, so that the monitoring device may not meet a certain explosion-proof standard. Meanwhile, since the remote communication module 40 and the image acquisition module 20 in the present application are all high power consumption modules, if a single power supply line is adopted, the power consumption of the power supply line is too high, the explosion-proof requirement cannot be met, and the load requirement on the power supply line is too high, so that safety accidents are easy to occur. Therefore, in order to meet the requirement of safe power supply under the explosion-proof standard, the embodiment of the invention is provided with a plurality of power supply lines aiming at the power consumption condition of the module. For example, different power supply lines are provided for the image acquisition module 20 and the remote communication module 40, respectively, so as to supply power to the image acquisition module 20 and the remote communication module, respectively, so that the loads of the respective power supply lines are not excessively high and the requirements of explosion-proof standards can be met.
For the image acquisition module 20, it can monitor various orientations of the construction site so as to be able to acquire image information of various orientations of the construction site.
The data processing module 30 is connected to the image acquisition module 20, and performs data processing on the acquired image information. Meanwhile, the data processing module 30 transmits the processed data to the remote communication module 30.
For the remote communication module 30, network access without dead angles to the construction site can be realized, and the acquired data of the construction site can be effectively ensured to be uploaded to the background in real time.
According to the monitoring equipment provided by the embodiment of the invention, on one hand, 360-degree dead angle-free monitoring can be realized by adopting the multi-path cameras, and compared with manual monitoring, the monitoring dead angle is avoided; on the other hand, through the safe processing of the external power supply signal, the operation safety of each module of the monitoring equipment is ensured, and a plurality of power supply lines are arranged according to the power consumption condition, so that the requirements of explosion-proof standards are effectively met, and the method is more suitable for complex and severe construction sites in petrochemical industry; on the other hand, by processing and uploading the image information in real time, the background can monitor the condition of the construction site in real time, and timely discover the abnormality in the construction site, so that the safety of the construction site is further improved.
The modules described above are described in further detail below in conjunction with the accompanying figures.
In a preferred embodiment, as shown in fig. 2, the power supply lines provided by the power management module include: the first power supply line 2 is connected with the image acquisition module 20 and is used for providing the processed power supply signal to the image acquisition module 20; the second power supply line 3 is connected to the data processing module 30 for supplying the processed power supply signal to the data processing module 30 and via the data processing module 30 to the remote communication module 40.
For example, considering the importance of image acquisition in a construction site, and that the image acquisition is real-time, the power consumption is relatively large, and the first power supply line 2 in the embodiment of the present invention is directly connected to the image acquisition module 20 to provide the processed power supply signal thereto. The data processing module 30 is connected to the remote communication module 40, and the operation of the remote communication module 40 is based on the power provided by the data processing module 30, so that the second power supply line 3 according to the embodiment of the present invention is connected to the data processing module 30, and is capable of providing a processed power signal for the operation of the data processing module 30 on the one hand, and providing the processed power signal to the remote communication module 40 via the data processing module 30 on the other hand.
It should be noted that, the embodiment of the present invention is not limited to only setting the first power supply line and the second power supply line, and those skilled in the art may set other power supply lines according to the actual module configuration of the monitoring device and the power consumption of the module, so that the monitoring device meets the explosion-proof requirement during operation.
In the embodiment of the invention, through the power consumption conditions of the image acquisition module and the remote communication module, corresponding power supply lines are respectively arranged for the two modules, so that the overload of the power supply lines is avoided, the safety and the reliability of the power supply process are improved, and the explosion-proof requirement is further effectively met.
In a preferred embodiment, as shown in fig. 3, the power management module includes: the safety processing unit comprises a first anti-interference circuit 101, a current limiting and soft starting circuit 102, a second anti-interference circuit 103, a DC-DC conversion circuit 104 and an overvoltage protection circuit 105 which are connected in sequence.
For example, the first anti-interference circuit 101 includes a transient voltage suppressor, a common mode inductor, and a magnetic medium capacitor. The transient voltage suppressor is connected in parallel with the input end, so that the damage to the circuits of all modules of the monitoring equipment caused by the surge of the power supply input can be prevented. The common mode inductance is used to reduce high frequency common mode noise in the power supply signal to reduce radiation. The parallel ceramic capacitor can reduce interference signals brought by power signals. In addition, since the operating voltage of the monitoring device according to the embodiment of the present invention is 12VDC, the reverse cut-off voltage of the transient voltage suppressor should be greater than 12V.
The second anti-interference circuit 103 includes an electrolytic capacitor and a porcelain capacitor, wherein the electrolytic capacitor not only can filter out high-frequency interference, but also can be used as an energy storage element, and the energy can be continuously provided for each module of the monitoring device by discharging at the moment of inflation. The ceramic capacitor can filter the voltage of the output power signal of the power module.
For the current limiting and soft start circuit 102, it is possible to limit the start-up rush current of the various modules of the monitoring device to a reasonable range. For example, the soft start chip may have its soft start turned on when each module is powered up, and the soft start time is adjustable. In addition, the circuit also adopts a plurality of serially connected circuitsThe resistor limits the maximum output current in the circuit. The series resistor is a current sampling resistor for detecting and regulating the output current in the circuit and limiting the output current I with the circuit OUT The following relationship is satisfied:

For example, for the first anti-interference circuit, a transient voltage suppressor, a common mode inductance, and a magnetic medium capacitance are included.

The ceramic capacitor can filter the voltage of the output power signal of the power module.
For current limiting and soft start circuits, it is possible to limit the start-up surge current of the various modules of the monitoring device to a reasonable range. For example, the soft start chip may have its soft start turned on when each module is powered up, and the soft start time is adjustable. In addition, the circuit also adopts a plurality of resistors connected in series to limit the maximum output current in the circuit. The series resistor is a current sampling resistor for detecting and regulating the output current in the circuit and limiting the output current I with the circuit OUT The following relationship is satisfied:
wherein V is output voltage, R 2 The resistance of the current sampling resistor. From the above relation, it can be seen that the resistor R is sampled based on the current 2 The impact current can be limited to a set range. In addition, if the input current or the working current of the load equipment exceeds the limit range, the circuit chip can enable the circuit of the whole safety module to enter a protection mode, so that an error power supply signal is prevented from being provided for other modules.
For the DC-DC conversion circuit, the DC-DC conversion circuit has the over-current, over-voltage and thermal protection functions, and has the advantages of high output efficiency, small ripple, stable output voltage range, continuous output current and the like.
The overvoltage protection circuit is positioned at the output end of the DC-DC conversion circuit, wherein the circuit adopts a zener diode or a controllable silicon design, and can play a role in preventing the damage of each module circuit when the output voltage is too high. Since the power of the zener diode is generally within 5W, according to the related explosion-proof standard, if the zener diode is used as the output overvoltage protection device, the input current I of the power signal IN The following should be satisfied:
I IN ×V Z ×1.5≤P W
wherein V is Z Is the voltage stabilizing value, P of the overvoltage protection device W For rated power of the overvoltage protection device, the formula shows that when the input current is too large and the voltage stabilizing tube cannot meet the intrinsic safety explosion-proof requirement, the design of the overvoltage protection circuit can be carried out by adopting the silicon controlled rectifier. Assuming that the input end current limit value of the designed power supply circuit is 250mA, an SMBJ5342 voltage-stabilizing diode (voltage-stabilizing value V) with rated power of 5W can be adopted Z 6.8V) is connected in parallel to the output of the circuit for overvoltage protection. And then according to the formula, the following calculation is carried out:
250mA×6.8V×1.5＝2.55W＜5W
therefore, it should be noted that, in the design of the overvoltage protection circuit, when the zener diode is selected, the overvoltage protection must meet the related explosion-proof requirement.
In addition, because the electrolytic capacitor, other capacitors, inductors and other devices exist in the circuit in the power management module, and the devices can influence the intrinsic safety performance of the whole circuit, in order to ensure that the whole monitoring equipment meets the intrinsic safety requirement, the power management module needs to be placed in a shell made of PVC and is sealed by epoxy resin, so that the devices are prevented from influencing other circuits.
Further, the power management module further comprises a self-powered unit for providing power to each module within the housing for a predetermined period of time.
For example, the self-powered unit may be a high-capacity intrinsically safe battery, and may provide high endurance under conditions meeting explosion-proof standards, for example, 3-4 hours of endurance may be achieved. That is, the above-mentioned time period of the preset time period is related to the capacity of the battery and the power consumption of each module.
In the embodiment of the invention, the power management module further ensures that the operation of each module in the monitoring equipment is more stable by adopting the circuit to safely process the external power signal. In addition, the monitoring equipment can support two power supply modes of site power taking and battery power supply through the self-powered unit, can realize uninterrupted monitoring for 7 x 24 hours of a construction site, especially when accidents such as explosion and fire occur on the construction site and the like cause external power supply damage, the self-powered unit can continuously supply power for each module operation, can continuously acquire explosion site images, can timely provide the explosion site images for a rear platform, provide omnibearing image information for a background commander, and further provide timely and effective support for command decision of the commander.
In a preferred embodiment, as shown in fig. 2, the image acquisition module 20 comprises the following cameras respectively connected to the data processing module 30: the multi-path camera 201 comprises a plurality of fixed-focus cameras capable of freely rotating and is used for acquiring multi-path image information of the construction site; and/or a zoom camera 202 for acquiring image information of a specific area or a specific object in the construction site; and/or an infrared thermal imaging camera 203 for monitoring changes in the ambient temperature of the job site or changes in the temperature of objects within the job site.
For example, in general, the existing monitoring device is only configured with a single-path camera, but the single-path camera has a certain monitoring blind area, so as to ensure that no dead angle monitoring is performed on 360 degrees of a construction site, the image acquisition module 20 of the embodiment of the present invention is configured with a plurality of paths of cameras 201, which can be installed by means of a guide rail or the like, and can perform 360 degrees of rotation. Specifically, as shown in fig. 2, the multi-path camera 101 is composed of a plurality of fixed-focus cameras, for example, four fixed-focus cameras. Each fixed-focus camera shoots real-time conditions of a construction site and correspondingly generates one path of image frames. For the embodiment of the present invention, the video transmission code stream of the multi-path camera 201 is considered to be large, and the required bandwidth is high. In order to ensure that the image data is uploaded to the background under the condition that the image is clear and does not get stuck, the data processing module 30 in the embodiment of the invention adopts a video code stream compression technology, when the image data is acquired by the called one-way camera, the main code stream is uploaded, and when the image data is acquired by the called multi-way camera 201, the sub-code stream is uploaded, so that the bandwidth required for uploading the image data can be greatly reduced, and the communication link pressure between the remote communication module and the background is reduced.
Since the multi-path camera 201 is composed of a plurality of fixed-focus cameras, the embodiment of the invention may further include the zoom camera 202 in addition to the multi-path camera 201 described above, considering that the fixed-focus cameras can only collect images of a construction site with a fixed focal length. The zoom camera can change focal length within a certain range to obtain different wide and narrow field angles, different size influences and different range lenses. Therefore, in order to improve the definition of the image of the construction site, the invention adopts the zoom camera, acquires the enlarged image of the target monitoring point position by increasing the focal length, and can also reduce the focal length to acquire the panoramic image within a certain range. Compared with a multipath camera consisting of fixed-focus cameras, the zoom camera 202 can flexibly acquire images in different sizes and different ranges, can acquire clear images of specific areas or specific objects in a construction site, and is convenient for a background to flexibly monitor the conditions of the construction site in different fields of view and clearly acquire images of target monitoring points. As shown in fig. 2, the zoom camera 202 is directly connected to the data processing module 20, and the collected image information is directly sent to the data processing module 20, so that the data processing module 20 performs data processing on the image information collected by the zoom camera 202.
In addition, when some light rays of a construction site are poor, a clear image cannot be obtained by adopting the multipath camera and the zoom camera, so the embodiment of the invention is also provided with the infrared thermal imaging camera which can be displayed by receiving infrared rays emitted by an object. Because any object with temperature can emit infrared rays, the embodiment of the invention can monitor the environmental temperature change of a construction site by adopting the infrared thermal imaging camera, can also find out the abnormal point position of the temperature change according to the temperature difference by acquiring the temperature distribution of the measured object based on the acquired infrared image, and can further effectively process the abnormal point position in time. As shown in fig. 2, the infrared thermal imaging camera 203 is connected to the data processing module 30 through an SOC chip (not shown) for image processing, which performs image processing on an infrared image of the infrared thermal imaging camera 203, and then transmits the processed image data to the data processing module 30.
For zoom cameras and infrared thermal imaging cameras, they may be mounted underneath with respect to the multiple cameras, either alone or in combination. Moreover, the image frames shot by the zoom camera and the infrared thermal imaging camera can be displayed in the background in a superposition mode and a branching mode. For superposition, the zooming video shot by the zooming camera and the infrared thermal imaging of the infrared thermal imaging camera are simultaneously operated by a background algorithm to carry out superposition fusion. Specifically, the superposition fusion is to capture images of the same frame by using two cameras, and to perform image registration processing (i.e. amplifying the same position of capturing the infrared image) on the image captured by the zoom camera and the infrared image of the infrared thermal imaging camera by using a background built-in algorithm, thereby performing image fusion. Based on this, the background can arbitrarily enlarge and view the infrared image for the construction environment, and further can check whether there is an abnormality in the construction site, for example, whether there is a leak in a pipeline in the construction site.
In addition, the multi-path camera and the zoom camera can be combined for use, and the images of certain monitoring points acquired by the multi-path camera can be arbitrarily amplified through the zoom camera. The multichannel camera can also be used with the infrared thermal imaging camera combination, and the backstage can acquire the temperature variation of a plurality of points of job site in real time, monitors whether unusual appears in job site.
