WSP-2000 Wireless Solar Power Monitor System

The solar wireless monitoring system utilizes inexhaustible and clean energy-saving solar energy and wind power.At the same time,the system uses advanced audio and video long-distance wireless networking technology to enable remote or inconvenient access to power supply.Uninterrupted monitoring is possible.With the maturity of solar wireless monitoring system integration technology,the system has been widely used in the world and has shown broad application prospects.

 

The system is mainly used in the field and in areas where the city is not convenient for wiring,such as: railway along the line,high-speed line,border line,coastline,army field training,oil and gas transmission pipeline,construction site,reservoir dam,river water source,mining area scenic spot,forest Fire prevention,cultural relics,roads,golf courses,fish farms,pastures,wildlife sanctuaries,surrounding areas,villas,islands,etc.Simply summarizing the place of “three noes”,that is,no one has no electricity and no network,but it needs real-time monitoring and management and needs energy-saving zero-emission and pollution-free places or areas.

 

The system can solve the problem that the road monitoring point has no mains power,and also solves the problem that the image transmission is not well wired; the application of the company's ball machine system can perform 360° comprehensive monitoring on the road near the monitoring point,and the monitoring range is wide and the image High definition and free transmission,managers can centrally manage all monitoring points in the equipment room,and the front-end monitoring points are fully automatic and do not require personnel to operate.Solar wireless monitoring is adopted by more and more public security road administration departments because of its high flexibility,strong scalability and simple maintenance.

Solar Power Subsystem

 

The system is mainly composed of a solar cell module,a wind power generator,a battery,a solar intelligent controller and the like.Solar modules and wind turbines convert light energy into electrical energy,and store electrical energy to the battery (charging) through the control of the solar intelligent controller and the intelligent controller of the wind turbine; when power is required,the controller switch is turned on to turn on the load,and the battery is placed in the battery.The electrical energy is supplied to the load (discharge).

The main function of the intelligent controller is to charge and discharge the battery.When the battery power supply is insufficient during the working time,the controller automatically cuts off the load power supply and over-discharges the battery.When the battery is continuously charged to full charge,the controller pairs The battery is overcharged; because the voltage output of the solar system fluctuates greatly,the BMS power management module provides a stable power protection for the load to prevent the camera from malfunctioning due to excessive voltage burnout or low voltage.The system uses the latest generation of MPPT solar intelligent controller,which can actively track the highest power point of solar modules,and adopts advanced multi-peak tracking technology.When the panel is shaded or some of the panels are damaged,the system controls The device can still accurately track the maximum power point,and can output more power through the maximum power tracking,thereby improving the charging efficiency; the MPPT controller can increase the charging efficiency by 30% compared with the ordinary pulsed PWM solar controller; the latest upgrade version supports cloudy days.Charge and support no battery operation.

 

Solar power generation is the main source of energy for the entire system.The size of the solar power supply system should be based on the total power consumption of the load equipment and the annual average annual sunshine of the project to comprehensively consider the system capacity,that is,to ensure the reliability of the system power supply.Also reasonable control of the cost of the power generation system.It must be noted that the area with severe haze must consider the negative impact of haze on the solar power supply system.According to the severity of the haze,the sunshine will be weakened or even equivalent to the rainy day; when the wind is emitted,the auxiliary power supply will be used continuously.Wind power generation becomes the only source of electricity replenishment in rainy days,which can extend the battery life,thus avoiding the paralysis of the power supply system in long rainy weather to a certain extent.

 

Many users have such a misunderstanding that the camera is powered by a solar cell module.In fact,the battery is powered by a battery.The solar cell module is only responsible for charging the battery,so the battery is also a very important part for the solar power supply system; Because the solar power supply system is in a state of large charge and discharge for a long time,and the battery is usually buried underground,

frequent replacement is time-consuming and laborious.Therefore,a maintenance-free energy storage type solar gel battery with reliable quality and long service life should be used; Use a longer-life lead-carbon colloidal battery or a lithium battery with a relatively high energy density and a supercapacitor at the cutting edge of technology to store electrical energy.

 

The battery is the energy source needed to maintain the system in the absence of sunshine.When continuous rainy days occur,the battery needs to have enough power to maintain the continuous operation of the entire system.Because the price of the solar battery is high,it cannot be considered because During the year,there will be several long rainy days and too many batteries are placed,which makes the battery configuration in a wasteful state for most of the time.The result of excessive configuration of the battery will inevitably lead to a significant increase in cost.Therefore,the solar power application system should allow for a low probability of occurrence of power shortage,and the independent power supply time of the battery is generally 4-10 days.

 

Misunderstanding of battery life time: Battery life time refers to the total discharge time to the battery loss when the battery is full.Just like the mobile phone's nominal battery life,it must be calculated when the battery is full.It is considered that the calculation is started at any time during the operation of the system,because the weather-based uncertainty is not necessarily full before the continuous rainy days.

 

The solar wireless monitoring system works differently than the ordinary wired monitoring system.The ordinary wired monitoring system can ignore the voltage and power of the camera or other load,and can also ignore the working time of the system.In the solar wireless monitoring system,the higher the power of the camera or other load and the longer the working time,the configuration of the system.The bigger it will be,the higher the price of the system will be.Due to the preciousness of solar power generation and battery storage,it directly affects the construction cost of the entire system.Therefore,the low-power operation of the load equipment in the whole system becomes the key to the solar monitoring system.

 

First,the voltage of the load device should be DC 12V as the camera should be selected.Many users choose the AC24V load device incorrectly.For example,the AC24V high-speed dome camera commonly used in the market,the power consumption of 24V3A is 72W (must pay attention to the power of some manufacturers' AC ball machine).Directly applying the power labeling of the DC dome machine,according to this error power calculation will lead to serious shortage or complete failure of the system power supply,

which not only causes serious power consumption of the system,but also causes power loss after multiple voltage conversions,and increases the inverse The transformer additionally increases the power consumption,and of course increases the system failure rate,and frequently occupies hidden dangers for future system operation problems.

 

Specific description of voltage conversion: If you choose AC24V ball machine,you need to increase the inverter (the inverter increases its own power consumption),convert the voltage from DC 12V to AC 220V(the power loss during conversion is about 14%),then add the adapter.Reduce the voltage from AC 220V to AC 24V(about 17% loss during conversion)

 

On the basis of serious power consumption,after several voltage conversions,the limited solar energy utilization rate was greatly reduced,which eventually led to a shortened

battery life in the rainy days and a frequent power outage.In addition,the drawback of

using AC 220V is the safety hazard of electric shock.Especially the unmanned

surveillance points in the wild are especially worthy of attention.

In order to solve this critical problem,we must formulate relevant standards for DC power supply for various load devices at the front end of solar wireless monitoring system,such as DC5V,DC9V,DC12V,DC24V and other conventional DC voltages,and unify them in the industry.

 

Secondly,the load device should select a low-power product based on the DC power supply to effectively reduce the system power consumption.In order to solve the problem of excessive power of ordinary cameras,the company has specially developed low-power laser energy-saving and solar energy-saving ball machines for solar energy systems.It uses a new low-temperature low-power laser technology,which saves 60% of energy compared with ordinary dot matrix lights.The latest dome PTZ power-saving circuit consumes half of the power of a conventional dome to obtain a longer battery life,which reduces the power consumption of the camera while meeting the night vision requirements and reducing the solar system.The power supply cost is especially suitable for solar monitoring systems that require extremely high power consumption in the field.

 

Since the front end does not require commercial power,each front-end monitoring point can save electricity costs of several hundred yuan per year; especially for large projects with a large number of points,the electricity cost is particularly impressive.

Wireless Video Transmission Subsystem

At present, there are three data transmission methods suitable for solar wireless monitoring, one is a microwave network based on a wireless bridge, and the other is a 3G/4G network based on a wireless platform operator. The third is the COFDM network. The three networks have different advantages, and the user can select them in a targeted manner.

 

If the user's monitoring point is within 20 kilometers from the monitoring center, and there is no occlusion in the middle, or it can be connected to the monitoring center by adding few relay points, this situation is more suitable for bridge transmission. Digital bridge transmission can achieve higher effective bandwidth and ensure the clarity and smoothness of video transmission; according to the user's site survey feedback (camera point, machine room point, obstacle point, can be used as the commanding height of the relay) Point location, distance between points) Select point-to-point, point-to-multipoint, signal bridging, signal relay, etc. or multiple ways to configure the wireless placement scheme; because the bridge is completely based on its own equipment for transmission, so The process is completely free. The communication frequency of the system bridge is 5.8G, which is the civil open frequency band allowed by the state. It can immunize the 2.3-2.7G frequency band signal interference, the bandwidth is 300M, it can easily transmit millions of high-definition video, and the proprietary airX-Beamforming and airX- Antiblocking technology, support automatic disconnection of disconnection; dual camera interface, built-in antenna; the company bridge has the advantages of long transmission distance, stable wireless link, large bandwidth, easy debugging, and access to dual cameras.

 

If there is a 3G/4G signal around the user's monitoring point, and there are many buildings or mountain blocks between the monitoring point and the monitoring center, or the distance between the monitoring point and the monitoring center exceeds the range of the bridge transmission, then 3G/4G video is used. Transmission will be a more appropriate choice. With 3G/4G video transmission, video data can be transmitted to the operator's server through the base stations of mobile, China Unicom, and telecommunications carriers all over the country without distance limitation, thereby accessing the Internet, and users can receive video at any Internet access point. Data; in particular, 4G solves the weak point of 3G bandwidth, the theoretical bandwidth 100M actual bandwidth 15-60M is much larger than 3G, so 4G can transmit millions of high-definition images in real time; using our company's H.264+ compression format camera, 4G transmission traffic In the default mode, it is about 150M/hour; since the 3G/4G point does not need to be associated with other points, the front-end construction is much easier than the bridge, and the point can be added indefinitely or at any time.

 

In the wild without 3G/4G signals, there are more mountain occlusions that can be transmitted by COFDM. COFDM has certain diffraction ability to penetrate obstacles and the ability to transmit on the move. Like the bridge, it is based on its own transmission. So the transmission is also free.

 

In summary, the bridge can transmit millions of high-definition video for free, suitable for areas with no or less occlusion; 3G/4G transmission can effectively overcome the obstacles blocking signals by various obstacles due to the support of a large number of base stations by operators. Or for ultra-long-distance video signal transmission, suitable for urban, village, suburban, hilly and rapid emergency applications; however, it must be noted that real-time transmission of images will generate high traffic charges, so the front-end video is combined with real-time transmission; For the standard, please consult the local mobile platform operator; due to the high equipment cost, COFDM transmission is mainly applied to the mobile individual equipment of the military, the high-end unmanned aerial vehicle, and the mobile individual equipment of the special administrative law enforcement department.

Video Surveillance Subsystem

Taking bridge transmission as an example, the image of the target monitoring point is collected by the camera, converted into a network digital signal by the network video module and sent to the digital bridge, which is wirelessly transmitted by the digital bridge to the bridge of the monitoring center, and then passed by the bridge. The RJ45 network cable is transmitted to the digital hard disk recorder or a computer host equipped with dedicated client software for video surveillance management control and video storage. The front-end camera can select a fixed camera or a 360-degree rotating dome camera according to the user's monitoring range requirements; according to the image quality requirements, 1.3 million pixels, 2 million pixels, and 4 million pixels can be selected (H.265 compression format) ) Digital HD cameras with different resolutions. According to the special requirements of users, the company can also provide special function cameras such as target tracking, alarm access, audio output, sensor access, fog, ultra-long-range lens and video analysis.

 

The system adopts standard RJ45 network communication port, which can realize seamless connection of different control terminals such as NVR, PC, mobile, and IPAD. When there is no external network, the system can support local video recording in the front end or local video in the computer room. Wired wireless remote monitoring of any node based on the Internet or mobile internet. Support multi-platform access cameras: such as digital hard disk recorder, computer browser access, software client access, mobile APP (Apple, Android), cloud access, WIFI hotspot access, etc., and support multiple users to access the camera at the same time; The center can know and control the working state of the front camera at any time. For example, adjust the camera menu, adjust the up, down, left and right of the dome camera to zoom in, manually or automatically focus the camera lens. Preset position setting, cruise track setting, query and playback of video. When there are a large number of monitoring points, you can choose to use our digital hard disk recorder or 4G monitoring management platform software for processing. If the user's display device is a video wall, another digital decoding matrix, a numeric keypad, etc. need to be configured.
