In the era of automobile yuan, foreign families have already popularized vehicles, and even each family owns several cars. In recent years, the domestic automobile manufacturing industry has developed rapidly, people’s living standards have improved significantly than before, and automobiles have entered thousands of households. On holidays, highways and scenic spots are full of cars. Traffic jams are inevitable. Traffic jams in developed cities are commonplace during peak commute hours. Traffic jams, difficult production suspensions, and automobile exhaust pollution have become a pain in big cities. When cars pass through toll road gates and parking lot entrances, slow barriers can no longer meet people’s demand for traffic efficiency. Especially with ETC or license plate recognition, the driver needs to brake to stop and wait for the brake lever to start before starting to pass. It is easy to cause pole collision, rear-end collision and exhaust pollution. The slow barriers provide conditions for the following vehicles to evade tolls. It is embodied in the following aspects:
A. One of mechanical limit switches, photoelectric limit switches, metal proximity switches, and Hall switches is set. As long as it is a switch, there are risks. The reliability of the switch itself, environmental climate, dust, etc., the choice of the switch Put forward higher requirements.
B. Due to the self-locking function of the worm gear structure, the rod cannot be automatically lifted after the power is off, causing traffic congestion and potential fire safety hazards. It is necessary to open the case and manually swing the motor’s handwheel to swing the brake lever, or a clutch device is set to manually open the clutch to lift the brake lever, which is time-consuming, laborious, and inefficient.
C. If the clutch device is set, it is generally connected and separated by keys. For high-speed moving parts, this design puts forward very high requirements on machining accuracy and hardness treatment. Otherwise, there is no reliability at all. Fast barriers The greater the mechanical wear, the more complex the mechanical structure, the worse the reliability of the whole machine and the shorter the life span.
D. In order to reduce the jitter of the gate lever during operation, traditional barrier gates or variable-channel gates are generally equipped with shock-absorbing rubber blocks at the limit position. The rubber blocks are prone to ageing in an outdoor environment, and the limit will be exceeded if maintenance is not timely. , The inertia caused by the rotation of the motor is large, causing an impact, and severely breaking the worm gear shaft or mechanical limit rod.
E. Although the variable frequency gate uses frequency conversion technology, the movement time of the first 45 degrees during the opening process can be increased compared with the traditional barrier gate, but the deceleration time of the latter 45 degrees is much longer than the acceleration time, so it is necessary to complete a start. The cycle time of the landing is relatively long, and it is not ideal for the city gates that require a large amount of car traffic.
The emergence of servo barriers is designed to solve the problem of slow vehicle traffic. After years of R&D technology accumulation, Shenzhen Zhongvan Technology Co., Ltd. has developed high-speed servo barriers (also known as: Servo railing machine). Servo motion control is used to accurately control the servo motor, and the high-precision planetary reducer is used to drive the railing, which realizes the PID closed-loop control of the running speed and acceleration, achieving fast and stable point-to-point.
Shenzhen Elefine Technology Co., Ltd. uses permanent magnet rare earth servo motors to drive high-precision planetary reducers to achieve the optimal combination. The efficient and concise mechanical transmission structure is innovative when applied to barriers. The high-speed servo barriers are highly efficient and fast. Running smoothly. Especially for high-speed barriers, the energy of impact increases exponentially with the increase of speed, and motion control is difficult to do well. The biggest feature of servo technology is that it can maintain a constant torque output at 0rpm speed, and the operation process is closed-loop controllable, point-to-point. Running smoothly. Speed, time and acceleration are adjustable. The simple and reliable mechanical structure provides a strong guarantee for the mechanical reliability and long life of high-speed servo barriers. Therefore, servo barriers are the first choice for expressways, bustling commercial centers, communities, and ports.
The service life of barrier gates is a headache for parking lot operators. Shenzhen Elefine Technology’s servo barriers have greatly simplified the mechanical transmission structure, with an average fault-free time of 5 million times, and the service life is more than 10 times that of traditional barriers, which is largely resolved. The embarrassing situation of the parking lot operators having to replace the barriers in one or two years. Among them, traditional barrier gates need to be regularly maintained and maintained. The high maintenance costs result in a greatly reduced utilization rate, and the final actual cost is higher, and the cost is more expensive.
As society progresses and people’s wages increase, labor costs are getting higher and higher, especially for skilled workers. Traditional barriers have always relied on technicians to go to the site for maintenance. Traditional barriers do not know that they are broken until they are used, which has already caused it. If the car can’t get in or get out, traffic jams will appear, which bothers drivers, users, and manufacturers at the same time. Shenzhen Elefine Technology’s servo barriers have fault self-checking and fault warning functions, which inform users in advance whether the barrier status is OK. If the barriers are faulty, what kind of faults exist, the fault information will be automatically reported, early warning, and maintenance personnel can quickly eliminate the faults , To minimize the impact (user use).
As the global climate changes, the winter temperature in some areas reaches -43°C, and ordinary barriers cannot operate at all. In the hot summer weather, the temperature in some places is as high as 40℃, and the surface temperature is 55~60℃. Under high temperature, most of the traditional barrier grease is liquid. The traditional barriers have been used for a long time throughout the year to heat up the gearbox oil seal or The accelerated aging of O-rings causes the oil leakage of traditional barrier gates to occur from time to time in summer, which further shortens the life of traditional barrier gates. Generally, there is no designed fuel filler opening, and it can only be worn dry after leaking. The temperature of the servo motor’s continuous operation is only a little higher than the ambient temperature (within 10°C). If the traditional barrier gate does not have a cooling system, and it runs continuously for 45 minutes at a normal temperature of 25°C, the internal temperature of the motor will reach 125°C, and the motor will be thermally protected, which will eventually cause it to fail to operate normally and even burn the motor coil. Servo barriers almost don’t generate heat during operation, so there is no overheating. Shenzhen Elefine Technology’s servo barriers will not have such a situation in summer. In the south, we often see some barrier gates at the gates of residential areas being used for many years without closing the lid or opening the door. It is because of frequent operation that they tend to generate heat. Although the motor power used by most traditional barriers is marked 50W or 80W, However, the actual power consumption measured by the power meter is more than 200W, and more than half of the power is used for the heating of the motor coil. Traditional barriers generally open the door to dissipate heat, and some even require fans to dissipate heat. Shenzhen Elefine Technology Servo Barrier operates normally at low temperature of -40℃ and high temperature of 80℃.
With the development of technology and the progress of society, we have entered the era of rapid development of the Internet of Things and automobiles. Long-distance card reading and high-speed license plate recognition are blooming everywhere. With high-speed servo barriers, the traffic speed can be increased by several times and the traffic efficiency can be improved by several times. Double, to prevent the occurrence of toll evasion with the car, you can immediately stop the car behind and pass after paying the toll. The electricity charges that the property community cares about are as follows:
Calculated by working continuously for 8 hours a day, (degrees = kilowatt hours)
Traditional barrier gate 200W working for 8 hours consumes 1.6 kWh/day
Shenzhen Elefine Technology Servo Barrier operates for 0.9 seconds without interruption for 8 hours and consumes 0.33 kWh/day
A barrier gate saves 1.6-0.33=1.27 degrees per day per day,
A barrier can save 1.27*365=463.55 degrees a year
Generally, a community has at least 2 entrances and exits, and 2 barriers save 463.55*2=927.1 degrees in a year.
This is a considerable amount of energy saving income. If everyone uses the servo barriers, how much coal resources will be saved for the country every year, this will be a very staggering number, and I cannot count. The above data is true and reliable, and it is actually measured by an external electric energy meter.
