[0055] The intelligent power supply unit supplies power to each power-consuming component based on the control of the integrated box operation and maintenance platform, monitors the electrical parameters of each intelligent integrated box in real time and sends them to the aggregation switch.

[0056] The present invention adopts the above technical solution, which has the following advantages:

[0057] 1. The existing video integrated box can only provide power supply and networking functions for the front-end camera. As a key node of the system, it does not monitor the operating status of itself and the upper distribution unit, becoming a data island in the subway Internet of Things network. It also does not have some intelligent applications to prevent and assist in locating faults, and is no longer suitable for current intelligent operation and maintenance requirements. The present invention can realize intelligent applications such as intelligent topology analysis, 3D visualization monitoring, fault path indication, parameter trend analysis, etc., to help operators achieve more intuitive monitoring effects, as well as fault warning and rapid location and troubleshooting of faulty equipment.

[0058] 2. In the existing video system, due to the lack of monitoring of the middle layer and terminal equipment, when a fault occurs, the level and position of the fault in the system cannot be quickly located, resulting in low time efficiency for operators to handle the fault. The present invention supports the fault path indication function. When a fault occurs, it automatically determines the fault type, fault level and location, and displays the precise location and network path of the faulty equipment on the preset station map, helping operation and maintenance personnel to quickly troubleshoot the fault.

[0059] 3. The integrated box in the traditional subway video system is powered by an air switch distribution unit without monitoring and time-sharing power-on functions. It is easy for the air switch to trip or short circuit to trip but the center is not aware of it. In addition, when the system loses power unexpectedly and restores power, the distribution unit carries a large number of integrated boxes and the instantaneous current is large, which easily leads to power-on failure. The present invention uses an intelligent power supply unit with monitoring and time-sharing power-on functions, which can upload the electrical parameters of the input and output circuits in real time. The equipment itself has short circuit, overvoltage, undervoltage, reclosing protection functions and time-sharing power-on and power-off control functions, and increases the power supply reliability through active protection, automatic recovery, and time-sharing control measures.

[0060] 4. In the prior art, when designing the power supply unit and integrated box in the system, the basic functions and cost reduction are often considered only, and the on-site installation, wiring and later disassembly and maintenance are rarely considered. This leads to inconvenient on-site wiring operation, unsightly process and difficulty in disassembly and maintenance after the failure of individual components. The present invention fully considers the routing path, fixation and wiring aesthetics of the connecting cables, and the disassembly and assembly of components do not interfere with each other and is convenient to operate.

[0061] 5. Compared with the traditional offline integrated box, the intelligent visual integration box of the present invention not only meets the camera power supply networking function, but also has a variety of operation status perception measures, including input and output side electrical parameter collection, environmental data collection, lightning protection status collection, security status collection, input side electrical protection, output side electrical protection function, and remote control function.

[0062] 6. Compared with traditional page list monitoring, the roaming inspection and monitoring function in the three-dimensional space model of the station adopted by the present invention can enable users to check the equipment operation status more immersively and grasp all elements of equipment space, time and current status.

[0063] 7. The monitoring, alarm, and trend analysis functions of the integrated box operation and maintenance platform of the present invention can effectively prevent the range of cameras from being disconnected due to the failure of the node aggregation equipment (integrated box, power supply unit). When the inevitable front-end equipment failure occurs, the automatic topology generation and fault path indication functions of the integrated box operation and maintenance platform of the present invention can help the operation and maintenance personnel quickly locate the fault point and power supply and networking path, and improve the efficiency of fault handling.

[0064] 8. The electrical protection and automatic bypass switching mechanism of the intelligent power supply unit of the present invention can effectively prevent and reduce the range of camera power-offline events caused by electrical failures and remote control module failures.

[0065] 9. The intelligent integrated box of the present invention adopts an adjustable angle power output terminal block, a partitioned spare fiber storage compartment, and an adjustable wire entry hole design, which can greatly facilitate the wiring and fiber splicing operations of construction personnel, improve the wiring accuracy and workmanship aesthetics, and at the same time improve the protection effect of cables and devices in the box.

[0066] In summary, the present invention can be widely used in the field of subway video surveillance. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] In the traditional subway video system, the network management platform used to monitor the operating status of equipment mainly monitors the equipment in the computer room, such as switches, storage and servers. The video integrated box of the key intermediate acquisition node is not monitored. The video integrated box carries the power supply and networking of the cameras in a certain area and is a key regional aggregation node device. The regional monitoring failure caused by the integrated box failure has occurred in various subway lines at different frequencies. And because the video integrated box does not have the remote transmission function, it is necessary to investigate the cause of the failure link by link, resulting in a very low timeliness in fault handling. The embodiment of the present invention provides a subway intelligent video integrated box operation and maintenance system, comprising a plurality of cameras, a plurality of intelligent integrated boxes, a convergence switch, an intelligent power supply unit and an integrated box operation and maintenance platform; each camera is arranged at a corresponding position of a station, and is used to collect image data at the corresponding position in real time; a plurality of cameras in a certain area of ​​the station are respectively connected to an intelligent integrated box arranged in the corresponding area, and the intelligent integrated box is used to obtain image data, input and output electrical parameters, environmental data of the location, lightning protection status data and security status data obtained by the corresponding camera and send them to the convergence switch, and provide networking and power supply for the corresponding cameras; the convergence switch is used to obtain data obtained by each intelligent integrated box and the intelligent power supply unit and send them to the integrated box operation and maintenance platform; the integrated box operation and maintenance platform is used to generate a network topology diagram according to the connected cameras and intelligent integrated boxes, display the operating status and electrical parameters of each camera and intelligent integrated box in real time, and automatically generate a path diagram including power supply path, network path and equipment location in the station plane base map when an offline problem occurs; the intelligent power supply unit is used to supply power to each electrical component based on the control of the integrated box operation and maintenance platform, and monitor the electrical parameters of each intelligent integrated box in real time and send them to the convergence switch. The present invention designs a monitoring platform specifically for the video integrated box and its upper power supply equipment, which can monitor the electrical parameters of the video integrated box and its upper power supply equipment, the switch status of the camera output circuit, environmental parameters, door lock status, lightning protection module status, etc. This helps the operator to monitor the system operation status globally without blind spots, and realizes fault prevention and rapid positioning and processing after the fault occurs.

[0083] Example 1

[0084] like Figure 2 As shown, this embodiment provides a subway intelligent video integrated box operation and maintenance system, including three layers: a front-end equipment layer, an intermediate collection layer and a monitoring platform layer. The front-end equipment layer includes a number of cameras 1, the intermediate collection layer includes a number of intelligent integrated boxes 2, a convergence switch 3 and an intelligent power supply unit 4, and the monitoring platform layer includes an integrated box operation and maintenance platform 5.

[0085] Each camera 1 is set at a corresponding position of the station, and the camera 1 is used to collect image data at the corresponding position in real time. Several cameras 1 in a certain area of ​​the station are respectively connected to an intelligent integrated box 2 set in the corresponding area, and several intelligent integrated boxes 2 are respectively connected to the aggregation switch 3. The aggregation switch 3 is connected to the integrated box operation and maintenance platform 5 of the train control room. The intelligent integrated box 2 is used to obtain the image data obtained by the corresponding camera 1, the input and output electrical parameters, the environmental data of the location, the lightning protection status data and the security status data and send them to the aggregation switch 3, and provide networking and power supply for the corresponding cameras 1. The aggregation switch 3 is used to obtain the data obtained by each intelligent integrated box 2 and the intelligent power supply unit 4 and send them to the integrated box operation and maintenance platform 5. The integrated box operation and maintenance platform 5 is used to generate a network topology diagram according to the connected cameras 1 and intelligent integrated boxes 2, and display the operating status and electrical parameters of each camera 1 and intelligent integrated box 2 in real time, and automatically generate a path diagram including the power supply path, network path and the accurate location of the equipment in the station plan when the camera 1 and the intelligent integrated box 2 are offline.

[0086] The intelligent power supply unit 4 is connected to the external power distribution cabinet. The intelligent power supply unit 4 is also connected to the aggregation switch 3 and each intelligent integrated box 2 respectively. The intelligent power supply unit 4 is used to power each electrical component based on the control of the integrated box operation and maintenance platform 5 through the power provided by the distribution cabinet, monitor the electrical parameters of each intelligent integrated box 2 in real time and send them to the aggregation switch 3, and automatically bypass the control loop to take power from the input side bypass when the remote monitoring and control of the integrated box operation and maintenance platform 5 fails (the control loop can realize the power-on or power-off of multiple outputs in sequence to prevent drastic changes in load from impacting the power supply system upward. The input side bypass refers to a loop that directly connects the input and output without control. It is an emergency power supply plan after control failure to ensure that the powered equipment does not lose power when the remote control module fails).

[0087] In a preferred embodiment, the camera 1 of the front-end device layer can adopt various types of cameras, including hemispherical, box-type, full-globe, face and panoramic cameras.

[0088] In a preferred embodiment, Figure 3 , Figure 4 and Figure 5 As shown, each intelligent integrated box 2 includes a chassis 2-1, a switch 2-2, an output safety device 2-3, a water immersion sensor 2-4, an adjustable bracket 2-5, a first output power terminal block 2-6, a second output power terminal block 2-7, an output lightning protection device 2-8, a fiber splicing box 2-9, an inlet 2-10, a spare fiber storage box 2-11, a measurement and control mainboard 2-12, a lightning protection module 2-13, an input circuit breaker device 2-14, a test socket 2-15, a main power supply 2-16 and an electromagnetic lock 2-17.

[0089] The bottom of the chassis 2-1 is provided with a switch 2-2, an output safety device 2-3, a water immersion sensor 2-4 and an adjustable bracket 2-5. The switch 2-2 is used for networking the front-end camera 1. The camera 1 aggregates the image data to the switch 2-1 through a network cable or an optical fiber, and then forwards it to the integrated box operation and maintenance platform 5 through the aggregation switch 3. The output safety device 2-3 is used to protect the intelligent integrated box 2 when the camera 1 is short-circuited or the load current increases sharply due to a fault, and the power supply circuit can be cut off when an abnormal situation occurs. The water immersion sensor 2-4 is used to collect information on whether the chassis 2-1 is flooded, soaked, or sprayed by a broken water pipe, and other extreme situations. The top of the adjustable bracket 2-5 is connected to the output lightning protection device 2-8 through the first output power terminal block 2-6 and the second output power terminal block 2-7 in turn. The adjustable bracket 2-5 is used to enable the first output power terminal block 2-6 and the second output power terminal block 2-7 to have a certain height and angle adjustment ability, helping the wiring personnel to see the terminal hole position clearly and have several times more hand movement space than before, reducing wiring misalignment, missed connection, and virtual connection. The output lightning protection device 2-8 is used to prevent the intelligent integrated box 2 from being damaged by lightning overvoltage, and when encountering a lightning overvoltage that penetrates into the chassis 2-1, the voltage is introduced into the ground. Located above the switch 2-2, a fiber splicing box 2-9 is provided in the chassis 2-1. The fiber splicing box 2-9 is used to splice the optical cable entering the box on the upper platform side, and communicate with the switch 2-1 through the optical jumper, thereby establishing an optical communication link from the switch 2-1 to the integrated box operation and maintenance platform 5.

[0090] A line inlet 2-10 is provided at the bottom of the chassis 2-1, and a spare fiber storage box 2-11 is also provided at the bottom of the chassis 2-1. The upper part of the spare fiber storage box 2-11 is provided with several flanges for connecting the main fiber of the camera 1, and the lower part of the spare fiber storage box 2-11 is provided with several storage compartments 2-11-1 for placing the spare fibers of the camera 1. Thin steel plates are used to separate the storage compartments 2-11-1 to prevent the spare fibers of the camera 1 of different circuits from being entangled and the flange optical connectors from being damaged by collision.

[0091] A measurement and control mainboard 2-12 is provided in the middle of the chassis 2-1, which is used to obtain the image data obtained by the corresponding camera 1, the input and output electrical parameters, the environmental data of the location, the lightning protection status data and the security status data.

[0092] The top of the chassis 2-1 is provided with a lightning protection module 2-13, an input circuit breaker 2-14, a test socket 2-15 and a main power supply 2-16. The lightning protection module 2-13 is used to output lightning strike status data when lightning strikes. The input circuit breaker 2-14 is used to protect the input side circuit and cut off the input side circuit when a short circuit or excessive load current occurs. The test socket 2-15 is used for debugging engineers or operation and maintenance engineers to debug the switch 2-1 and camera 1, and to provide power for the laptop computers and engineering test terminals used by engineers. The main power supply 2-16 is used to power various electrical components in the chassis 2-1. The chassis 2-1 is also provided with an electromagnetic lock 2-17 with status output.

[0093] Specifically, the measurement and control main board 2-12 is provided with an electrical parameter acquisition module, a temperature and humidity acquisition module, a gyroscope integration module, a door lock status acquisition module, an input side electrical protection module, an output side electrical protection module and a remote control module.

[0094] The electrical parameter acquisition module is used to collect the voltage and current data of the total input circuit and each output branch of the corresponding intelligent integrated box 2 (for example: if an intelligent integrated box 2 is connected to 10 cameras 1, then the intelligent integrated box 2 corresponds to one total input circuit and ten output branches) through a voltage divider circuit and a sampling resistor, and to calculate electrical parameters such as total power, power consumption and power factor.

[0095] The temperature and humidity acquisition module is used to collect temperature and humidity data in the chassis 2-1.

[0096] The gyroscope integrated module is used to collect the dumping status data of the chassis 2-1 and output an alarm signal when the chassis 2-1 falls off from the installation point or leaves the installation point.

[0097] The door lock status acquisition module is used to obtain the status data of the electromagnetic lock, so as to output an alarm signal when there is a problem with the electromagnetic lock 2-17, such as the operation and maintenance personnel forget to close the door or the illegal personnel pry the lock and damage it.

[0098] The input side electrical protection module is used to provide overvoltage, undervoltage, overcurrent and short circuit protection. When the collected electrical parameters are abnormal, the output is automatically stopped to protect the front-end powered equipment.

[0099] The output side electrical protection module is used to prevent the entire intelligent integrated box 2 from triggering input side protection power failure due to a power supply circuit failure of a certain camera 1 through the fuse protection device set in the output circuit of each camera 1.

[0100] The remote control module is used to enable the integrated box operation and maintenance platform 5 to remotely shut down any camera 1 as needed through the relay control circuit set in the output circuit of each camera 1.

[0101] Specifically, in order to meet the requirements of station halls and platform wall installation, chassis 2-1 adopts a thin design of 600mm (width) × 800mm (height) × 160mm (depth), so that it can be hidden under the station wall decorative panel.

[0102] Specifically, in terms of weather-resistant design, chassis 2-1 is made of hot-dip galvanized carbon steel spray-coated material, which has excellent corrosion resistance and economy.

[0103] Specifically, in order to make the box body more compact, a plurality of hanging ears 2-18 are provided on the outer side of the chassis 2-1.

[0104] Specifically, in order to improve the heat dissipation capacity of the chassis 2-1, louvered heat dissipation windows 2-19 for convection heat exchange are arranged at the positions corresponding to the main transformers on both sides of the chassis 2-1, and filters are arranged on the inner sides of the louvered heat dissipation windows to prevent dust accumulation.

[0105] Specifically, in order to improve the waterproof capability of the chassis 2 - 1 , the chassis 2 - 1 uses sheet metal flanges and foamed polyurethane sealing strips.

[0106] Specifically, in order to improve the blocking effect of the chassis 2-1, as Figure 6 As shown, a movable baffle is slidably connected to both sides of the cable inlet 2-10 of the chassis 2-1, and two adjustment slots are arranged in parallel and offset on each movable baffle. Corresponding to the position of each adjustment slot, a limit column is arranged on the chassis 2-1. The moving distance of the movable baffle is determined by the adjustment slot and the limit column, and the size of the cable inlet 2-10 can be adjusted within a certain range, thereby reducing the gap between the cable and the cable inlet 2-10 and making the fire-proof mud adhere more firmly. The adjustment slots and the limit columns are staggered to form a staggered two-point fixation, strengthen the connection and fastening force between the movable baffle and the chassis 2-1, and prevent the movable baffle from tilting. The two sides of the movable baffle are bent to enhance the overall rigidity. The front end of the movable baffle matches the guide angle design of the cable inlet 2-10 to prevent the sharp edge of the steel plate from damaging the cables entering the box.

[0107] In a preferred embodiment, the intelligent power supply unit 4 is provided with a circuit protection module, a power supply controller module, an operation monitoring module and a master-slave switching module.

[0108] The circuit protection module is used to protect the circuit of the intelligent power supply unit 4 through overvoltage, undervoltage, overcurrent and short circuit protection.

[0109] The power controller module is used to remotely start and stop each channel and start and stop in sequence. When the system is powered on, the output is enabled channel by channel at fixed intervals. When the system is shut down, the output is stopped channel by channel to prevent excessive instantaneous load changes, which may cause fluctuations in the power supply network and affect system stability.

[0110] The operation monitoring module is used to monitor the electrical parameters of the input branch and each intelligent integrated box 2 in real time, including voltage, current, power, etc., and upload them to the integrated box operation and maintenance platform 5 through the aggregation switch 3.

[0111] The active-standby switching module is used to automatically bypass the control circuit and take power from the input side bypass when the remote monitoring and control of the integrated box operation and maintenance platform 5 fails, thereby preventing the camera 1 from regional power failure and offline, reducing the scope of the fault, and playing a bypass disaster prevention function.

[0112] Specifically, the intelligent power supply unit 4 is installed in a compact rack. The size of the intelligent power supply unit 4 is a 1U standard chassis 2-1, which is easy to assemble and disassemble, and saves 2U space compared to an air-disconnected power distribution unit. The intelligent power supply unit 4 uses rear terminal wiring to enhance the operating space and field of view.

[0113] Specifically, Figure 7 As shown in the figure, it is a schematic diagram of the bypass disaster prevention function of the main and standby switching module. The incoming line of the intelligent power supply unit 4 is located at Figure 7 In the lower right corner, normally the power goes through the power controller module and the main-standby switching module to each output circuit, and the power controller module performs branch start and stop or sequential start and stop operations; when the intelligent power supply unit 4 control circuit self-detects a fault, the main-standby switching module switches to the backup power to bypass all control functions and directly supply power, thereby ensuring that the front-end equipment can still work normally.

[0114] In a preferred embodiment, Figure 8 As shown, the integrated box operation and maintenance platform 5 adopts a B / S architecture, including a management module, a background service module, a Mysql database and a three-dimensional display module, wherein the background service module includes an intelligent integrated box interface service module, an intelligent power supply unit interface service module, a Zookeeper distributed coordination service module, an Activemq message service module and a communication middleware service module.

[0115] The management module is used to perform configuration management on each intelligent integrated box 2 and intelligent power supply unit 4 based on the data sent by each intelligent integrated box 2 and intelligent power supply unit 4.

[0116] The intelligent integrated box interface service module is used to obtain the data sent by each intelligent integrated box 2.

[0117] The intelligent power supply unit interface service module is used to obtain data sent by the intelligent power supply unit 4.

[0118] The Zookeeper distributed coordination service module is used to send the data received by the intelligent integrated box interface service module and the intelligent power supply unit interface service module to the management module.

[0119] The Activemq message service module is used to classify the received numerical values ​​(such as voltage and current), status values ​​(online and offline) and alarm signals (overvoltage, overtemperature) and send them to the management module. For example, the alarm signal is sent to the alarm management module of the management module, and the numerical values ​​and status values ​​are sent to the equipment monitoring module of the management module for dynamic update.

[0120] The communication middleware service module is used to send a corresponding alarm signal to the management module according to the type and level of the alarm information after the intelligent integrated box interface service module or the intelligent power supply unit interface service module obtains the alarm information of the front-end device.

[0121] Mysql database is used for data storage.

[0122] The three-dimensional display module is used to configure each device (intelligent integrated box 2, camera 1, intelligent power supply unit 4) on the station three-dimensional map, and display the status and operating parameters of each device in real time on the station three-dimensional map according to the spatial position of each device (intelligent integrated box 2, camera 1, intelligent power supply unit 4).

[0123] Specifically, the management module includes an intelligent topology module, an equipment monitoring module, an alarm management module, a historical data module, an equipment archive module, a configuration maintenance module, a statistical analysis module, a fault location module and a user management module.

[0124] The intelligent topology module is used to communicate with each intelligent integrated box 2 through the SNMP network management protocol, obtain the IP address of each camera 1 connected to it, and automatically generate a network topology map for real-time display. By comparing with the pre-configured network topology map of the intelligent integrated box 2, the online percentage of the terminal device and the network status can be intuitively grasped; it is also used to convert the automatically generated network topology map into a pre-configured network topology map.

[0125] The equipment monitoring module is used to display the operating status and electrical parameters of each intelligent integrated box 2 and intelligent power supply unit 4 in the system in the form of equipment controls, including the start and stop status of the input / output circuit, the main circuit / bypass status, the voltage, current and power of each circuit, etc., and remotely control each intelligent integrated box 2 on the equipment control.

[0126] The alarm management module is used to display various alarm signals that appear during system operation, including protection action, component failure, circuit disconnection, and electrical / environmental parameter out-of-limit alarm signals. Among them, the alarm signals include three levels: general alarm, important alarm and emergency alarm. The alarm signals include four states: unconfirmed and unrecovered, unconfirmed and recovered, confirmed and unrecovered, and confirmed and recovered.

[0127] The historical data module is used to query the historical data of a certain parameter through parameters such as time period, signal type and name.

[0128] The equipment archive module is used to input parameters such as the model, brand and service life of each intelligent integrated box 2, intelligent power supply unit 4 and each camera 1, so as to facilitate operation and maintenance personnel to query equipment information, purchase spare parts and query corresponding technical documents. The platform can also remind operation and maintenance personnel to inspect and replace equipment at different time points according to the general electronic product life curve to ensure the healthy operation of the system.

[0129] The configuration maintenance module is used to enter the name, drawing equipment number, IP address and point table information of the device to be connected. For the intelligent power supply unit 4 and the intelligent integrated box 2, the point table information includes the start and stop status of each circuit, electrical parameters, environmental parameters, protection action information and self-test information.

[0130] The statistical analysis module is used to automatically generate a line graph based on time period, equipment number and telemetry measurement (electrical parameters, environmental data) name to reflect the changing trend of the selected telemetry measurement within a certain period of time, and assist operation and maintenance personnel in analyzing faults or judging the health status of equipment and environment.

[0131] The fault location module is used to automatically generate a path map including the power supply path, network path and the exact location of the equipment in the station plan when the camera 1 or the intelligent integrated box 2 goes offline, based on the network topology, power supply topology and the location of the equipment. This helps the operation and maintenance personnel to understand the equipment-related situation intuitively and clearly and troubleshoot the problem quickly without having to identify the problem based on the drawings.

[0132] The user management module is used to set different user groups and user group permissions (such as viewing, controlling, downloading, deleting data permissions, etc.) according to usage requirements, set different user names, passwords and the user groups they belong to according to the list of operation and maintenance personnel, and provide user group and user addition, deletion, modification and query functions.

[0133] Specifically, Fig. 9 As shown in the figure, it is a schematic diagram of the network topology of the intelligent topology module. The right side of the figure is the network topology pre-configured according to the design drawings and the initial IP planning, including the IP, number and type information of each camera 1; the left side of the figure is the network topology automatically generated after the system is powered on and the network is adjusted. Among them, green means that it has passed the comparison with the preset network topology and no processing is required; red means that it is compared with the preset network topology to determine the offline items; blue means that it is compared with the preset network topology to determine the extra items; after the whole station is compared, it can be clearly determined at a glance that the camera 1 is missing, offline, or wrongly connected, thereby helping the debugging and operation and maintenance personnel to quickly handle it.

[0134] Specifically, Fig.10As shown in the figure, it is a schematic diagram of the path map generated by the fault location module. After the number of the faulty camera 1 is input into the fault location module, the system automatically jumps to the position of the camera 1 in the station plan, and identifies the position and number of the camera 1 in the area (marked by the red circle in the figure) and the intelligent integrated box 2 (the blue SBX box in the figure), and automatically generates the power supply path of the faulty camera 1 (the blue dotted line in the figure), and identifies the relevant power cord and network cable models on the interface (the blue square box in the figure). This function can provide the operation and maintenance personnel with all the information required for fault handling, thereby speeding up the fault handling time.

[0135] Specifically, the specific working process of the three-dimensional display module is:

[0136] Using the actual 3D model of the station as the carrier, according to the spatial location of the equipment, assemble the equipment elements in the 3D map of the station and define the equipment. After the equipment definition is associated, the relevant operating status and parameters can be displayed on the 3D map. The display methods include manual dragging, zooming, and roaming inspection according to the preset path. In the inspection state, every time you arrive at a scene, the real-time operating parameters of nearby equipment will automatically pop up, so as to achieve a monitoring effect of what you see is what you get.
