Description
Technical field
The present invention relates to a kind of electric car method for limiting speed, specifically, relate to a kind of tramcar using beacon speed limit
Method.
Background technique
Electric car is the important component of urban track traffic, since electric car is usually in ground running, and it is big by location
Mostly bustling location, causes the speed control of electric car in the process of moving particularly important, produced by contingency caused by exceeding the speed limit
Loss can not estimate, so need to carry out electric car speed stringent control, and usually control section is automation control, meeting
Monitoring device will usually be added to ensure traffic safety by host crash or other fortuitous events occur, and monitoring device is usually only
There is 1 velometer, excessively rely on the stability of velometer, is easy to cause to test the speed because velometer is unstable inaccurate.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, to provide a kind of design science, dispersion hardware risk, survey
The method that a kind of high, the adaptable tramcar of fast stability utilizes beacon speed limit.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of tramcar utilizes beacon speed limit
Method, including the onboard system with beacon antenna being mounted on tramcar and the take a message target trackside uniformly distributed along speed limit area
Equipment, each trackside equipment, which mutually concatenates, realizes data interchange, realizes speed limit by following steps:
1) when, electric car passes through a certain trackside equipment, record by the time, when electric car passes through next trackside equipment, record through
Spend the time；
2), trackside equipment includes processor, and twice were asked poor by processor, obtains duration of the electric car Jing Guo two trackside equipments, and
It compares with the duration of setting；
3), if duration is less than setting duration, it is judged to exceeding the speed limit, sends a speed limit order to third trackside equipment, third
Trackside equipment records the time and speed limit order is sent to onboard system, onboard system receives speed limit when electric car passes through
Order starting braking at once, controls the speed of service；
4), in the section being transmitted across after speed limit order, if processor still judges that electric car exceeds the speed limit, it is marked as burst thing
Therefore sound an alarm to remote control center, artificially interfered.
Described on base, the mobile unit includes the single-chip microcontroller of beacon antenna and connection electric car control unit.
Described on base, in step 1), processor makes marks to each trackside equipment, marks and bundlees with the temporal information provided,
When discovery is intermediate has omission to mark, issues equipment damage information and give remote control center, while continuing to execute step 2, and right
Setting duration in step 2 is compared multiplied by after 2.
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, and specifically, the present invention exists
Several trackside equipments are arranged in speed limit region, and record electric car passes through the time, by pair for calculating difference and preset value by the time
Than judging whether electric car exceeds the speed limit, then assigning speed limit order, if electric car does not slow down still, prove that electric car breaks down, send
Alarm is artificially interfered to remote control center.
Further, if the intermediate trackside equipment that there is damage leads to miss record, continue to record it is next, and will be right
It is compared than duration multiplied by 2, the risk of detecting element damage is reduced, the dependence of discrete component reduced, stability
It is improved.
Specific embodiment
Below by specific embodiment, technical scheme of the present invention will be described in further detail.
A kind of method that tramcar utilizes beacon speed limit, including the vehicle with beacon antenna being mounted on tramcar
Loading system and the take a message target trackside equipment uniformly distributed along speed limit area, each trackside equipment mutually concatenate realize data interchange, by with
Lower step realizes speed limit:
1) when, electric car passes through a certain trackside equipment, record by the time, when electric car passes through next trackside equipment, record through
Spend the time；
2), trackside equipment includes processor, and twice were asked poor by processor, obtains duration of the electric car Jing Guo two trackside equipments, and
Compare with the duration of setting, when setting the duration passed through of a length of electric car normally travel, corresponding plus-minus can be done according to error,
The error amount in allowed band can also be added；
3), if duration is less than setting duration, it is judged to exceeding the speed limit, sends a speed limit order to third trackside equipment, third
Trackside equipment records the time and speed limit order is sent to onboard system, onboard system receives speed limit when electric car passes through
Order starting braking at once, controls the speed of service, no matter train exceeds the speed limit in which position, can make a response at once, control
It slows down, and small to the dependence remotely controlled, the degree of automation is higher；
4), in the section being transmitted across after speed limit order, if processor still judges that electric car exceeds the speed limit, it is marked as burst thing
Therefore sound an alarm to remote control center, artificially to be interfered, continuous hypervelocity occurs or electric car control system goes wrong,
Either communication system goes wrong, and requires artificially to interfere, be overhauled at once, avoids bringing bigger problem, so that it is sent out
Existing problem is especially timely.
The mobile unit includes the single-chip microcontroller of beacon antenna and connection electric car control unit, and single-chip microcontroller mainly handles data
Transmission and compiling.
Wherein, in step 1), processor makes marks to each trackside equipment, marks and bundlees with the temporal information provided, works as hair
When thering is omission to mark among existing, it was demonstrated that equipment damage issues equipment damage information and gives remote control center, while continuing to execute step
It is rapid 2), and the setting duration in step 2 is done so and equipment damage bring just greatly reduces multiplied by comparing after 2
Risk is more stable by testing the speed in risk spreading to multiple equipment.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
