Description
Technical Field
The utility model relates to a power supply system, in particular to a traffic induction power supply system based on capacitance, belonging to the technical field of road safety; the application also relates to a traffic guidance system.
Background
The low-visibility traffic guidance equipment is particularly suitable for suburban roads, mountain roads and over-crossing bridges, and can save power supply construction and use funds; and secondly, providing guarantee for traffic safety under the condition of insufficient visibility (at night, heavy fog and the like).
The low visibility traffic guidance systems on the market in recent years all have the following characteristics: the energy storage device is powered by green energy, a lithium battery (such as ternary lithium, lithium iron phosphate and the like) is adopted as an energy storage device in a clear color, electric energy is obtained through solar energy, wind energy and the like, and then the lithium battery is used as the energy storage device. The energy-saving solar water heater is powered by green energy in daytime or in windy days, and simultaneously, the energy is stored by a lithium battery.
Solar energy is generally utilized through photovoltaic power generation techniques. The photovoltaic power generation technology is a technology for directly converting solar energy into electric energy and directly converting light energy into electric energy by utilizing the photovoltaic effect of a semiconductor interface. A key element of this technology is the solar cell. The solar cells are connected in series and then are packaged and protected to form a large-area solar cell module, and then the photovoltaic power generation device is formed by matching with components such as a power controller and the like. Photovoltaic power generation has the advantage of being less geographically constrained because sunlight generally illuminates the ground; the photovoltaic system also has the advantages of safety, reliability, no noise, low pollution, no need of consuming fuel and erecting a power transmission line, on-site power generation and supply and short construction period.
In the process of acquiring solar energy through photovoltaic power generation, the solar energy is used for charging a battery through an MPPT technology. The MPPT controller can detect the generated voltage of the solar panel in real time and track the maximum voltage current Value (VI), so that the system charges the storage battery at the maximum power output. The solar photovoltaic system is applied to a solar photovoltaic system, coordinates the work of a solar cell panel, a storage battery and a load, and is the brain of the photovoltaic system.
The direct output voltage of the independent energy storage device is low, and the low voltage is generally converted into the high voltage through a direct current boosting technology. The dc boost is to boost the lower dc voltage provided by the battery to the required voltage value, and the basic working process is as follows: the high frequency oscillation generates low voltage pulse, the pulse transformer boosts the voltage to a preset value, the pulse rectification obtains high voltage direct current, and therefore the direct current booster circuit belongs to one type of DC/DC circuits.
At present, in the existing low visibility traffic guidance system using a rechargeable battery as an energy storage element on a mountain road, the current situation of no-lamp illumination on the mountain road is mainly solved, a wireless ad hoc network technology is adopted, all lamps are ensured to synchronously emit light, the light intensity is consistent, and the performance in night and foggy weather is very excellent.
However, in the using process, it is found that in autumn and winter in mountainous areas, severe weather such as long-term continuous overcast and rainy days (about 40 days at the longest) is easy to occur, and environmental influences such as leaf shielding exist, which causes insufficient illumination intensity and exhaustion of battery power, in order to ensure normal operation of the system or temporary inspection in daytime, the battery needs to be replaced or replenished and charged on site, the former causes greatly increased maintenance cost, the latter greatly increases operation and maintenance time, and mountainous area roads are narrow in road width and are linearly bent, and a charging vehicle occupies a lane for a long time (low charging efficiency of a storage battery), which is neither safe nor inconvenient.
In addition, due to the physical characteristic of limited charging and discharging times (800-; the operation and maintenance cost rises rapidly; meanwhile, the recycling of the storage battery is not mature at present.
Therefore, how to make the low visibility induction system longer-lasting, reduce the operation and maintenance cost, and improve the operation and maintenance efficiency is a technical problem to be solved urgently by those skilled in the art.

In a first embodiment of the present application, the power supply system charges the energy storage capacitor with the electric energy generated by the renewable energy power generation device through the charge controller. The electric energy of the energy storage capacitor is boosted by the boosting device and then externally supplied with power under the action of the power supply controller. Specifically, a constant-voltage power supply end of the boosting device supplies power to the power supply controller, and the power supply controller controls a constant-current power supply end of the boosting device to supply power to the outside. The technical scheme that this application provided utilizes the electric capacity as energy storage equipment, can improve power supply system's security, increase of service life, extension equipment service temperature environment improves power supply efficiency, practices thrift production and maintenance cost.
In a first embodiment of the present application, the voltage boosting apparatus boosts the voltage output by the energy storage capacitor for the second time through the first voltage boosting circuit and the second voltage boosting circuit. Thereby improving the utilization rate of the electric energy of the energy storage capacitor.
It should be noted that, if the capacitor is simply replaced according to the prior art, since the capacitor has no obvious voltage platform, the voltage drop of the capacitor is substantially proportional to the stored power, so that when the stored power is excessive, the output voltage drops to the point that the peripheral circuit cannot normally operate, and the utilization rate of the capacitor power is less than 40%. In order to solve the problems that the energy density of the capacitor is small, the volume is large, no obvious voltage platform exists and the like which affect practical application, the utilization rate of the stored electric quantity in the capacitor is improved to more than 85 percent through a secondary boosting circuit structure, so that the capacitor energy storage mode meets the application requirements in the fields of traffic induced illumination and the like, the characteristics of long service life, wide-temperature work and quick charging of the capacitor are fully exerted, and the working intensity and the maintenance cost of maintenance personnel can be greatly reduced.
In a first embodiment of the present application, the first boost circuit is specifically a boost voltage stabilizing circuit including a UC3843 controller; and the second boost circuit is a low voltage boost circuit including a B3P49 boost controller. Due to the adoption of the first boost circuit of the UC3843 controller, when the voltage is lower than the starting voltage of the UC3843 controller, the UC3843 controller cannot work. Therefore, the capacitor is boosted by the second boost circuit adopting the B3P49 controller, so as to ensure that the first boost circuit including the UC3843 controller works normally.
It should be noted that, measured: when the second booster circuit adopting the B3P49 controller is not added, and the voltage of the energy storage capacitor is reduced to 3.9V, the first booster circuit adopting the UC3843 controller cannot continue to output. According to the scheme provided by the invention, when the energy storage capacitor can be discharged to less than 1V (the lowest voltage can reach 0.8V), the load can still be driven to normally work, namely, the external normal power supply is realized. The utilization rate of the stored electric quantity of the energy storage capacitor can be greatly improved.
In a first embodiment of the application, the voltage boosting device monitors the output voltage of the energy storage capacitor in real time through the power supply voltage monitoring module, and when the output voltage of the energy storage capacitor is higher than the starting voltage of the UC3843 controller, the power-on change-over switch directly transmits the electric energy of the energy storage capacitor to the first voltage boosting circuit through the standard voltage direct supply circuit; when the output voltage of the energy storage capacitor is lower than the starting voltage of the UC3843 controller, the power-on switch is switched, the electric energy of the energy storage capacitor is led into the second booster circuit on the ultra-low voltage booster circuit, and is boosted by the second booster circuit and then led into the first booster circuit.
In the first embodiment of the present application, the MPPT controller can detect the power generation voltage of the renewable energy power generation device in real time, and track the maximum voltage and current value, so that the system charges the energy storage capacitor with the maximum power output, and the MPPT controller is widely applied to power generation technologies with frequently changed power generation voltages, such as solar power generation and wind power generation.
In the first embodiment of the application, through the backup battery, when the electric quantity of the capacitor is exhausted, the normal operation of the communication module which is communicated with the outside and a power supply system is ensured, and maintenance personnel are reminded to maintain the equipment.
In a second embodiment of the present application, the inducing controller provides the light emitting device with the electric power of the power supply system of the first embodiment when the light intensity is lower than a certain value according to the light intensity of the external environment sensed by the light sensing sensor, thereby lighting the light emitting device. So that certain lighting or route guidance is provided for the road.
In the third embodiment of this application, the light intensity of the external environment that the induction controller sensed according to the light-sensitive sensor, when light intensity was less than a certain value, utilized the electric energy of first embodiment power supply system to provide the electric energy for sound generating mechanism to realize the sound prompt guide on the road.
It should be noted that, the long-acting low-visibility traffic guidance systems are networked by a wireless grid network module, so that the long-acting low-visibility traffic guidance systems in the same region are linked in real time.
It should be noted that the wireless mesh network module is specifically a mesh module or a LoRaWAN module. A Mesh network, i.e., a wireless Mesh network, is a multi-hop (multi-hop) network, is developed from an ad hoc network, and is one of key technologies for solving the problem of the last mile. In the process of evolving to the next generation networks, wireless is an indispensable technology. The wireless mesh can be cooperatively communicated with other networks, and is a dynamic and continuously expandable network architecture, and any two devices can be wirelessly interconnected.
It should be noted that, in the prior art, a lithium battery pack is mostly used for energy storage, and the scheme has the following technical problems: 1. the charge-discharge service life is short (about 3000 times or 2 years) and particularly has great influence on the service life of the battery in a state of complete power consumption; 2. the replenishing charging rate is slow, and the maintenance is troublesome; 3. the capacity is greatly influenced by temperature, particularly by a lithium iron phosphate battery, and the capacity is reduced by 60 percent at the temperature of minus 10 ℃; 4. the maintenance and recovery of the storage battery is cumbersome and immature.
The capacitor adopts a common capacitor as an energy storage element, has wide temperature range (-40-65 ℃), long charge-discharge service life (more than 500000 times or 6 years), can carry out high-rate quick supplementary charging on site, does not need maintenance, has mature recovery processing mode, and can properly solve the problems.
It should be further explained that the technical solutions of the existing similar products all use rechargeable batteries as energy storage elements. Lithium series batteries were used, including: ternary lithium, lithium iron phosphate, lithium titanate, lead-acid batteries, and the like. The ternary lithium battery has the advantages of high voltage platform (3.7V), high energy density and good low-temperature performance (about 20% of capacity reduction at minus 10 ℃) compared with lithium iron phosphate. The disadvantages are poor safety and short life. In terms of charging and discharging times, 3000 times are applied abroad, and 1000 times can be applied at home and 800 times. The actual service life is about 2 years. And secondly, the lithium iron phosphate battery is mainly applied to the field of power. Its advantages are high safety and high speed charge and discharge speed of 2C. The charge-discharge life is about 2000 times. The disadvantages are that: the energy density is low, the voltage platform is low (3.2V), the low-temperature performance is poor, and the capacity is reduced by 45-60% when the temperature is minus 10 ℃. Third, the lithium titanate battery has the advantages of good safety, excellent quick charging performance, long service life, cycle charging frequency of more than 30000 times and ideal service life of 10 years, and can be charged and discharged at high rate. The low-temperature performance is excellent, and the coating can be normally used in an environment of-50 to 60 degrees. The disadvantages are that: the energy density is low, and the cost is high; the voltage platform is low and is only 2.3V; the market share is low, the product type is single, the market invests the development of the product at present, and the model required by the project is not available in the product type at present. Fourth, and finally lead-acid batteries, are not comparable to the above-described batteries in terms of energy density, bulk weight and life, and the only advantage is their low cost, which is not compared here.
In summary, the solution using a rechargeable battery as an energy storage element has the most concentrated problems as follows: 1) and (4) safety. The most prominent problem is that the ternary lithium battery can cause violent combustion or explosion when being maintained improperly or subjected to strong vibration or impact; 2) the number of charging and discharging times and the service life. The charge and discharge times of the main stream ternary lithium and the lithium iron phosphate battery are not more than 3000, and the service life is 2-3 years; 3) the working temperature range is narrow, and the low-temperature performance is poor. The lithium iron phosphate battery has the outstanding problem that the capacity is greatly reduced along with the reduction of the ambient temperature (minus 10 degrees). The method has no practical application value basically in northern regions; 4) the recharge is slow. Taking the most widely used ternary lithium battery and lithium iron phosphate battery as examples, the charging current is generally 2-3A. The full charge at least needs more than 2 hours according to the capacity of the battery pack of 6000mAH and the charging current of 3A.
It is important to point out that the electrolytic capacitor is adopted as the energy storage element, compared with the battery scheme, the battery has the advantages of good safety, more than 500000 times of cyclic charge and discharge and 6-10 years of service life; the working temperature range is wide and can reach-40 to 65 degrees. Over-discharge has no significant effect on life. The market reservation is huge, and specification door class is complete, and the technical threshold is very low. The high-rate charging can be carried out on site, the charging time can be over 10 ℃, the charging can be greatly shortened, the capacitor can be normally used after being charged for 2 minutes, the capacitor can be fully charged in 15 minutes, and the recovery of the capacitor is mature and environment-friendly at present.
The invention adopts a common capacitor as an energy storage element, has wide temperature range (-40-65 ℃), long charge-discharge service life (500000 times or more than 6 years), can carry out high-rate quick supplementary charge on site, does not need maintenance, has mature recovery processing mode, and can properly solve the problems.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. according to the technical scheme, the capacitor is used as an energy storage element, and the capacitor has long-acting, low-maintenance and wide-temperature working performance. The number of times of charge and discharge is 500000, and the service life is 6-10 years. The capacitor overdischarge has no great influence on the service life.
2. The effective operating voltage of the capacitor ranges from a nominal voltage to 0.8V or less. The load is driven to work through boosting and current stabilization (voltage stabilization). The electric quantity stored by the capacitor is utilized to the maximum extent, and the utilization rate can reach more than 85%.
