Distribution box (i.e. console), is equipped with the electrical equipment such as control, measurement, signal on panel.Protection distribution box is mainly used as technique scene
Power distribution equipment.
(3) drawer-type distribution box.This kind of distribution box makes closure using steel plate, passes in and out the electric elements of line loop all
In the drawer that can extract out, constitute and can complete a certain class and power the functional unit of task.Functional unit and bus or cable
Between, the feature board that is made with the metallic plate being grounded or plastics separates, and forms bus, three regions of functional unit and cable.Per
Also there are quarantine measures between individual functional unit.Drawer-type distribution box has higher reliability, security and interchangeability, is comparison elder generation
The distribution box for entering, distribution box majority refer to drawer-type distribution box.They be applied to require the higher industrial and mining enterprises of power supply reliability,
Skyscraper, used as central controlled distribution center.
(4) power, light distribution distribution box.Mostly closed right angle setting.Because use occasion is different, shell protection grade
Also different.They are mainly as the power distribution equipment of industrial and mining enterprises production scene.
Distribution box application of the prior art is excessively single, lacks data acquisition function and radio communication function, it is impossible to right
The concrete condition of its region is monitored, and cannot carry out wireless controlled according to monitored results to surrounding cities service point naturally
System, for example, cannot carry out the Self Adaptive Control based on neighbouring stream of people's quantity to the opening time of surrounding cities service point.
Accordingly, it would be desirable to a kind of new traffic intersection distribution box, in addition to possessing basic distributing function, also has waterproof
Function, while the people's flow data near can gathering, the opening time to surrounding cities service point carries out controlled in wireless, so as to
In the case of not increasing multi-hardware equipment, further Optimizing City resource.
Content of the invention
In order to solve the above problems, the invention provides a kind of intellectuality waterproof electrical distribution box, improves itself
Waterproof effect, meanwhile, in the case of new data collection station is not increased, using existing traffic intersection distribution box near
Stream of people's quantity is acquired, and as the reference data of traffic intersection nearby urban service point opening time, and collects on distribution box
Become Wireless Telecom Equipment to complete the remote real_time control to multiple urban service points around.
