Technical Field

The invention relates to the technical field of traffic auxiliary appliances, in particular to an intelligent automatic snapshot movable traffic signal lamp and a using method thereof.

Background

In the process of increasingly rapid urban modern construction, urban safety problems are still in the forefront. For the crossroads with traffic signal lamp faults, temporary traffic signal lamps need to be placed to meet the road traffic requirements. Aiming at the analysis of the temporary traffic signal lamp used on the existing road, the signal lamp only can play a role of simple reminding, and cannot monitor and record the behavior violating the traffic rules, so that the aim of maintaining traffic safety cannot be really fulfilled.

At present, only a few cities place movable traffic signal lamps or temporary warning lamps on roads without traffic signal lamps or traffic signal lamp faults, but most of the cities have no way to draw attention of people, the attention is also a warning effect, illegal traffic rules cannot be recorded, and people are relaxed in thinking. Secondly, the position of the common movable traffic signal lamp is not easy to see clearly in rainy days or dark nights, so that potential safety hazards are caused. The system can not help public security organs to quickly find out the owner of the troublemaker and the criminal personnel at the position without the traffic signal lamp or the fault of the traffic signal lamp after the traffic accident occurs.

The solar power generation system consists of a solar battery pack, a solar controller and a storage battery (pack), and interaction of inverters is required. The field of solar power generation starts earlier in China. In the new century, under the support of great force of the country, the photovoltaic industry in China has leap. By 2009, the production scale of solar cells has reached the first world in China. Although the technology of the photovoltaic industry in China is mature, the technology is in the forefront of the world. In the future, the global competitiveness of the photovoltaic industry in China will be continuously enhanced. However, the solar power generation in China currently occupies not high power generation capacity of the whole power system. According to the data of the national statistical bureau, the solar power generation only accounts for 2.54 percent of the national full-aperture power generation amount at present. Therefore, the solar thin film power generation technology has a huge development prospect in the future.

At present, ordinary warning light is switched on and off manually, so that not only is human resources wasted, but also energy is wasted. The brightness of the warning light in the daytime is the superposition of the illumination of the sunshine and the light, and only the illumination of the light is available at night. When the sunlight illumination is too high in the daytime, the warning lamp is turned on, so that resources are wasted, and the potential safety hazard exists when the warning lamp is not lighted at night or cannot be turned on in time due to insufficient sunlight illumination in rainy days.

Disclosure of Invention

The technical problems to be solved by the invention mainly comprise the following points: the problem that the light and the placement position of the ordinary temporary traffic signal lamp are not striking at night or in rainy days; the technical problem that the ordinary temporary traffic signal lamp cannot expand the monitoring range and snapshot the behavior violating the traffic signal lamp in real time, so that vehicles do not obey traffic rules and the safety problem of more pedestrians and vehicles in running is easily caused; the technical problem of how to measure and judge whether the pedestrian and the vehicle have illegal behaviors according to the actual conditions of different roads by the common temporary traffic signal lamp; the problems of low service life, weak conductivity, poor stability and the like of the traffic signal lamp battery; the problems of energy loss, waste and the like caused by long-time lighting of the traffic signal lamp;

the invention adopts a targeted technical scheme, provides an intelligent automatic snapshot movable traffic signal lamp which is provided with ultrasonic ranging and light sensation technology to sense the turn-on of the lamp, and aims to solve the technical problems, wherein the specific scheme is as follows: the light sensation technology is introduced, and the effect of automatic switch of the warning lamp is achieved. When the illumination intensity is lower than 50Lux, the four-wall warning lamp is automatically turned on, and when the illumination intensity is higher than 50Lux, the four-wall warning lamp is automatically turned off.

For reaching the technological effect of real time monitoring snapshot, to foretell automatic snapshot's of intelligence portable traffic signal lamp, wherein surveillance camera head equipment is as innovative design, the technological effect of the real time monitoring that ordinary interim signal lamp did not possess has been increased, utilize solar energy film power generation technology to prolong the life and the reinforcing electric conductivity of battery simultaneously, stability and for monitoring camera plate and lighting system provide the energy, make road monitoring management more have the commonality, the administrator can indoor observation road traffic condition, it is stronger to compare the pertinence in ordinary interim signal lamp.

In order to achieve the technical effect of expanding the monitoring range, the bidirectional snapshot camera is arranged to carry out 90-degree rotation monitoring, the two cameras are connected through the central rotating shaft, the monitoring equipment is considered to be effectively utilized to the maximum degree, the road condition is practically monitored, when one road is a red light, the camera can automatically turn to and carry out snapshot monitoring on illegal behaviors, meanwhile, the positioning transmission systems such as the SIM card and the WiFi are also utilized to transmit data to the large database, public security policemen can conveniently know the road condition in real time or track and investigate the road condition afterwards, therefore, the intersection traffic order without traffic lights or traffic lights with faults is effectively maintained, and the function of detecting the illegal behaviors of pedestrians and vehicles, which is not possessed by common temporary traffic lights, is also solved.

In order to achieve the technical effect that whether illegal behaviors of pedestrians and vehicles occur or not can be correctly measured and judged by the temporary traffic signal lamp according to actual conditions of different roads, a sound wave measurement technology is introduced aiming at a snapshot technology utilized by a camera, and in order to enable intelligent real-time monitoring and warning equipment to effectively save energy according to the actual conditions, the sound wave measurement technology is mainly introduced to achieve through a sound wave sensor. The specific ultrasonic ranging method is an inclined triangular ranging method. The distance between the equipment and a parking line, the height of the ultrasonic module and the distance between the ultrasonic module and the parking line form a right triangle, the inclination angle formed by the transmitted sound wave and the vertical direction is 75 degrees, and the following calculation is carried out according to the sine theorem: the ultrasonic module is located the height equipment and stop line distance tan75, reaches the crossroad that adapts to different distances through adjustment ultrasonic module and carries out the purpose of taking a candid photograph, for the person of facilitating the use carries out the range finding simultaneously and adjusts the ultrasonic height, adds the overlength tape measure in the equipment bottom and satisfies the requirement of different crossroad range finding and through calculating the distance that the different heights corresponded on class adjusting the pole to reach the person of facilitating the use's purpose. The user only needs to place this equipment at the center of the crossroad that does not have traffic signal lamp or traffic signal lamp trouble, takes out the tape measure, and the distance of measuring equipment and stop line, then will adjust the altitude mixture control of pole to the distance department that corresponds on the scale, can take a candid photograph.

The intelligent automatic snapshot movable traffic signal lamp combines the light sensation technology, the ultrasonic distance measurement technology and the solar thin film power generation technology. Compared with the common temporary mobile traffic lights, the intelligent traffic light monitoring system is more humanized, the warning and monitoring effects of the intelligent real-time monitoring traffic light equipment can be fully displayed by monitoring whether pedestrians and vehicles cross the line illegally and run the red light, and the redundant consumption of energy is saved on the premise of fully exerting the light warning effect.

In the scheme, ultrasonic ranging is the core part of the whole device, and the measured data can judge whether illegal behaviors such as crossing lines or running red lights appear in pedestrians and vehicles or not by comparison according to the distance range set by contacting with the actual road condition, so that the snapshot reaction made by the camera equipment is directly influenced. An acoustic wave sensor is a device that performs acoustic-to-electrical conversion. The device can transmit the echo of sound wave and receive the sound wave, and convert the echo into corresponding electric signals.

The acoustic wave is one of mechanical waves, and the propagation process generates mechanical vibration, which consumes energy. The sound wave energy is gradually reduced along with the continuous propagation of the sound wave in the air, and the reduction of the sound wave energy is represented by the reduction of the amplitude because the sound wave energy and the amplitude have positive correlation. When the sound wave propagates in the air, the amplitude gradually decreases in an exponential manner along with the increase of time, and the specific reduction degree is mainly determined by the temperature and the sound wave scattering condition. The sound pressure attenuation law of sound wave propagation in air is as follows:

P_g＝P₀e^-ag (1)

wherein, P_gRepresents the sound pressure of the sound wave at position g; p₀Represents the sound pressure of the sound wave at the initial position; a represents an attenuation factor; g represents the distance of the obstacle from the source of the acoustic wave emission. The sound intensity attenuation law of sound wave propagation in air is as follows:

I_g＝I₀e^-2ag (2)

wherein, I_gRepresents the sound intensity of the sound wave at position g; i is₀Representing the sound intensity of the sound wave at the initial position. The decibel number Q of the decrease in the sound intensity gain is:

Q＝20algeV_ut (3)

wherein, V_uVoltage gain is shown and acoustic wave travel time is shown at t. The processing of the acoustic obstacle ranging signals is completed through the above process, and preparation is made for the following acoustic obstacle ranging signal fusion.

And fusing the acoustic wave obstacle ranging signals based on the processed acoustic wave obstacle ranging signals and a maximum likelihood method to provide signal data support for final obstacle distance calculation. The maximum likelihood fusion method can greatly improve the reliability of the acoustic wave sensor, so that the relative error of the ranging algorithm is reduced. Suppose that the output signal data of the ith acoustic wave sensor and the jth acoustic wave sensor is x_i，x_jThen the acoustic wave sensor relative confidence distance is expressed as:

wherein d is_ijDenotes x_iFor x_jA confidence distance of; p_i(x/x_i) Is shown when x_iProbability density at meanA function; s_iRepresents P_i(x/x_i) And (x)_i，x_j) The enclosed curved side area; d_jiDenotes x_jFor x_iA confidence distance of; p_j(x/x_j) Is shown when x_jProbability density function when it is mean value; s_jRepresents P_j(x/x_j) And (x)_j，x_i) The enclosed curved edge area. The likelihood function derivation by the maximum likelihood method is adopted to obtain the fusion result of the acoustic wave barrier ranging signals

Wherein σ_i，σ_jRespectively representing likelihood parameters of the ith and the j th sensors, x is a discrete random variable, P_xAs a function of probability of sound pressure correspondence, I_xAs a function of the probability of correspondence of sound intensity, P_x·I_xQ is the decibel number of the decrease in the sound intensity gain for the corresponding probability function product.

The obtained fusion result of the acoustic wave obstacle distance measurement signals is not optimal, and accurate obstacle distance cannot be obtained. The kalman filter algorithm is a linear state equation and performs optimal estimation on signal data input.

Setting an obstacle distance state equation as follows:

wherein the content of the first and second substances,represents the obstacle distance state at time t; f_tRepresenting an obstacle state transition matrix; b is_tRepresenting a control input acoustic signal vector; u. of_tThe control amount at time t is shown.

The predicted distance of the construction point at the moment t and the speed of the pedestrian and the vehicle are as follows:

wherein, P_tRepresenting the predicted obstacle distance at time t; a is_tRepresents the vehicle acceleration at time t; v_tRepresenting the vehicle speed at time t. Then the acoustic wave obstacle ranging signal fusion optimization equation is as follows:

setting the acoustic propagation process noise covariance matrix as R, taking state F as an example, which includes two elements of position p and velocity v, where F ═ p, v]，F^TIf the error state is, the acoustic wave obstacle ranging signal fusion estimation covariance equation is as follows:

on the basis of the process, a clock model is constructed, mathematical description is carried out, and the fractal method is utilized to analyze and research the sound wave propagation process. Based on the result of fractal feature analysis, a covariance matrix of Kalman filtering is estimated, so that the accuracy and efficiency of sound wave propagation are improved. The clock model calculation steps are as follows:

for the sequence x_iCalculating the mean value m:

calculating the average dispersion sequence Y: y is_i＝X_t-m+ξ₂(t＝1，2，...，n) (11)

Calculating a cumulative dispersion sequence Z:

calculating the range R:

R_t＝R_t＝max(Z₁，Z₂，...，Z_t)-min(Z₁，Z₂，...，Z_t)+ξ₄(t＝1，2，...，n) (13)

calculating a re-normalized range sequence (R/S):

and calculating to obtain the condition that the power law distribution between the R/S and the clock point model is satisfied, namely: (R/S)_t＝c·t^H (15)

Taking logarithm at two ends, obtaining:

log(R/S)_t＝log(c·t^H)+ξ₅＝log c+Hlogt+ξ₅ (16)

finally, the integration of the two can obtain:

in the calculation step of the clock model, xi 1 is a modification coefficient of the mean value m, and xi₂Modification coefficient, ξ, for the average dispersion sequence Y₃To accumulate modification coefficients of the dispersion sequence Z, ξ₄Modification coefficient, ξ, for the range R₅The power law distribution relation between the R/S and the clock point model is a modification coefficient, and H is a Hurst index. The clock point model is constructed on the basis of the Kalman filtering algorithm, and a plurality of modification coefficients are constructed at the same time, so that the unavoidable errors in the clock point model are reduced, the accuracy of the clock point model is improved, and then the following conditions of the t value are integrated, and the operation efficiency of the clock point model is improved. The intelligent real-time monitoring warning equipment light ranging algorithm research based on sound wave measurement is realized, the accuracy is improved, meanwhile, the efficiency is improved, and more effective guarantee is provided for the safety of the pedestrians and vehicles in traveling.

This application has introduced solar energy film power generation technique for the power supply of surveillance camera module, and the technique is the non-silicide material type from the material, is different from ordinary battery material, and its electric conductivity is stronger, and stability is more strengthened, has improved simultaneously because of the silicon purification has the problem that the degree of difficulty influences the conversion rate, and most importantly, more lengthens in traditional battery life film power generation technique battery life than.

According to the photovoltaic maximum power tracking Method, a four-section type Conductance Incremental Method (included conductivity Method) is adopted for photovoltaic maximum power tracking (MPPT) in the solar power supply module, namely, the solar cell works at the maximum power point by adjusting the voltage of the working point of the solar cell, calculating the differential of power and voltage and adjusting the output voltage, so that the efficiency DC/DC is improved. The solar cell array can reduce the requirement of the inverter on the input voltage of the solar cell array through a Boost mode of the direct current converter. Photovoltaic module selection

The model of SunpowerSPR-305-WHT-D has the peak efficiency of 18.7 percent, and the photovoltaic installation inclination angle can automatically correspond to the region latitude. The energy storage battery adopts a lead-acid battery with mature technology and relatively low price. The storage battery is connected with the direct current bus through the bidirectional half-bridge DC/DC converter, and can be controlled by using a Buck or Boost mode according to the charging and discharging requirements of the storage battery, so that the bidirectional flow of electric energy is realized, and the voltage of the direct current bus is stabilized.

The four-section type variable-step conductance incremental method is realized as follows:

the step adjustment coefficient s (k) of the conductance increment method is expressed as:

in the formula, U (k), I (k) are the voltage and current output by the photovoltaic cell at time k, P is the output power, Δ P is the output power variation, Δ I is the current variation, and Δ U is the voltage variation. In order to ensure that the variable step length range of the system work is optimal, a threshold upper limit N is set for S (k)_maxMedian value of threshold N_midAnd a lower threshold N_min，A four-section step length disturbance method is adopted, and the step length selection rule is as follows. If S (k) is not less than N_maxStep size is selected as Δ N_max(ii) a If N is present_min＜S(k)＜N_maxSelecting the step length as delta U; if N is present_min＜S(k)＜N_mid，The step size is selected to be delta U²2; if S (k) is less than or equal to N_min，Adopting variable step size, wherein the step size is selected to be S (k) delta U, and delta N_maxIs the upper limit value of the step length, Delta U is the disturbance fixed step length, Delta U²The/2 is disturbance stagnation step length, and S (k) delta U is variable step length. FIG. 5 is a diagram showing the relationship between S (k) and P-U curve. It can be seen that when the P-U curve reaches the maximum power point a, the value of s (k) becomes 0, i.e. point B in fig. 5; as the voltage increases, in the portion where the slope of the P-U curve is greater than 0, the value of S (k) is first approximated to N_maxThen gradually decrease to N_minAnd sharply decreases to 0 near the maximum power point; as the voltage continues to increase, the S (k) curve begins to rise back to 0 in the portion where the slope of the P-U curve is less than. The power curve is divided into a left part and a right part by taking the maximum power point as a demarcation point, wherein each part is divided into three sections I, II, III and IV according to the size of S (k), and each section adopts a different step size disturbance mode. In order to ensure the convergence of the algorithm to the right of the maximum power point, the upper limit value N of S (k)_maxIs set to 1, the lower limit value N_minThe determination needs to be made in consideration of the dynamic response time and the steady-state accuracy of the photovoltaic system. After the built photovoltaic system is simulated for many times, the lower limit value N is finally determined_minWhen the time is 0.3, the response time of the system is fastest and the steady-state precision is higher.

In order to transmit monitoring data to a database, a SIM card is inserted into the equipment, a WiFi module and a GPS module are established, and the GPS module is used for positioning and the WiFi module to link a traffic light to control a camera and transmit the monitoring data to the database.
