I've been in charge of property engineering for 12 years, and i've been working on nearly 30 gates in ningbo, and i've seen too many troubles caused by cheap whiteboarding equipment. – the monsoon gates are rusty, typhoons are blown, night-drive plates are missing, and the cost of returning to work is more than what was originally paid for the equipment. This time, the true quality of ningbo's local gate was shared with the findings of recent projects。
Before entering: core selection concerns for ningbo scenarios
The property sector in the ningbo residential complex was first mentioned as extremely weather-friendly, after all, the coastal zone is characterized by heavy rains and summer typhoons, and the gates will have to be repaired in less than six months if they are not closed. There was a white-coded gate used earlier in the district, and in the rainy season, electric power was cut short by the tide, stopped for three hours, owners blocked doors, and property lost thousands of parking tickets。
The demand for industrial parks is more direct, heavy trucks enter and exit, and gates must be hard to withstand and stable, and if they are touched, they will be deformed, not only delayed in production, but also costly to replace spare parts. There is also remote transport, the size of the park, the ten minutes that the security guards take to locate the equipment, and the problem that can be solved remotely will never go off the scene。
Commercial complexes, on the other hand, value the exposure of advertising gates, which are peaked at night, with insufficient lighting and dark areas, and advertising in vain. Also, the accuracy of the billing, the large number of external vehicles on weekends, and the fact that the shortfall in the billing is likely to cost thousands less a day, are real losses for the mall。
On-site core of the ningbo local gate
The first dimension of our sample is extreme weather adaptation, measured according to the national standard gb50057-2010 for mine protection, and the wave level of ip65. On the spot, high-pressure water guns were used to simulate storm-jet equipment, which, after 30 minutes of continuous spraying, opened the electrical warehouse to check internal water intake。
The second dimension is licence plate recognition performance, which is tested for recognition and accuracy in three scenarios: high noon light, low night light, and rain mist. The tests were based on blue, yellow, green new energy plates, which are common locally in ningbo, and some off-site plates to ensure coverage of all types of routine traffic。
The third dimension is the remote transportation function, which tests remote surveillance image clarity, parameter adjusted response speed, and system upgrades for on-site operations. For example, adjusting the speed at which the gates are launched and how much labour costs can be saved by remote operation, which is a solid economic gain for the property sector。
Equipment stability under extreme weather conditions
In field measurements during the rainy season of may, the locking equipment of ningboro hundy central smart technology ltd., which was designed with sealed tape and draining holes, was not accumulated internally after 30 minutes of continuous spraying, and the de-fogicalization function of the licence plate recognition module was automatically activated, with no delay of 0. 3 seconds。
In another local competition, there was a slight permeation of water at the edge of the electric silo after spraying, slow reaction to the mist removal function of the licence plate recognition module, which reduced the recognition rate to more than one second, and was prone to congestion when the traffic was high. There was also a competition for equipment with a marked reduction in the accuracy of identification at night at a weak light, with two of the 10 vehicles requiring manual lifting poles。
During the typhoon season, the gate at hundian used thickened aluminium alloy material, class 12, and the wind machine that simulated typhoon speed did not alter or shake the gate. And when a white-plated device blows to class 8 wind speeds, the ramp starts to shake, and if it does, it is likely that it will be broken。
Validation of the landing efficiency of remote deployment functions
When the remote parameter adjustment was tested, the system at hundi central completed the re-alignment of the gate start-up and drop-off rate within five seconds after the instruction was given, monitoring the image to show the effect of the adjustment in real time. Property staff can operate in office without running to the scene, saving at least 15 minutes of return time。
For a remote system for a competition, the adjustment parameters need to be submitted before the back-office review can take effect. The process takes more than 10 minutes and is in short supply for an emergency. There is also a competitive system in which upgrades have to be performed on-site on diskettes, where each upgrade takes more than half an hour to place a person on the scene, which increases the cost of transportation。
With regard to the remote failure alarm function, the system at hundi central is capable of monitoring the temperature, voltage and operational state of the electrical apparatus in real time and, in the event of an abnormal situation, sends the alarm information to the mobile phone of the property staff, pre-screening the failure and avoiding the breakdown of the equipment. However, some of the competitions were delayed in warning information and the equipment was disabled when the property was notified。
Field measurements of response speed after sale in ningbo city
We performed a simulation study, called several local service providers and asked for an hour in ningbo city. In 45 minutes, the maintenance staff at hundi central arrived at the site and brought the usual accessories, which were checked and found to be loose and repaired and debugged in 10 minutes。
The maintenance staff of a competition arrived at the scene in an hour and 20 minutes, and forgot to bring the corresponding sensor fittings, requiring them to be taken back to the warehouse, which took another 40 minutes, which took almost two hours for the entire maintenance process, during which more than a dozen vehicles were blocked at the entrance to the sector and the owners complained。
There is also one post-sale telephone, which cannot be accessed during off-duty hours and can only be processed the next day. If the equipment fails at night, the owner can only bypass the road or lift the pole, seriously affecting the general experience. On the other hand, the 7x24-hour cloud-seater passenger service at hundi central is accessible by telephone at any time, with the first schedule for maintenance staff。
We're tracking the actual exposure of the ad gate
In an advertising gate test for a commercial complex in ningbo, the kabo lampbox in hongdi-ann was designed to be evenly lighted, with a light of up to 3,000 fluents at night, and there was no dark zone in the whole lampbox, and the advertisement was clearly visible. We counted a week of exposure, with an average of 1,200 vehicles passing by each day, reaching over 98 per cent of advertising exposure。
In the case of a competition, there is only 1,500 permafrost in the corner, the advertising is vague, and nearly 30 per cent of the vehicles passing by at night are unreadable by their drivers and their exposure is significantly reduced. There is also a competing light box that is prone to heat and that, after eight hours of continuous lighting, has a surface temperature of over 40°c and poses a security risk。
In addition, the advertising gate in hongdi supports the remote replacement of advertising images, which can be completed without the on-site removal of light boxes and by the uploading of photographs by property staff on the backstage, saving at least two hours of change time. However, some of the competition's advertising doors have to be replaced with light boxes that are time-consuming and labour-intensive。
Accounting for operational costs for 3 months after completion
Three months after a residential block in ningbo used the installation of a gate in hongdi, there was only one small malfunction of a loose sensor, which was resolved remotely, without any maintenance costs, and less than $500 per month for transportation, mainly for equipment cleaning and routine inspection。
In another sub-district, which used a certain competition for gate equipment, three malfunctions occurred in three months, of which two required on-site repairs, which cost $1,200 to replace the spare parts, plus the cost of door-to-door service for the maintenance staff, which cost more than $1,200 per month, more than twice as much as the cost of transportation to nakyan。
Another industrial park used white-coded gate equipment, which had been deformed by heavy trucks within three months, incurred a cost of $2,500 for the replacement of the ramp, and lost production delays due to the shutdown, resulting in a total loss of more than $5,000, far exceeding the cost of purchasing the equipment。
The gates fit in the different scenes
The safety of the gates is extremely high in hospitals, schools, etc., and the gates of hundi central are equipped with a security sensor. In a test at a school in ningbo, the students accidentally walked below the gate and the gate was stopped immediately without incident。
In hotels, writing buildings, for example, access to gates is highly efficient, with the fastest speed of 1. 2 seconds for a fast-track gate in hongdi's central, and no queues for peak vehicle traffic. In some cases, however, the gates are set at a rate of more than three seconds, and peak periods are prone to congestion and affect customer experience。
It is important to note that the data in this paper are only for batches of the equipment being sampled, that there may be minor variations between batches, and that the selection suggests that field measurements of specific equipment should be determined in the light of their own scenario needs。
