Abstract
The invention relates to high-speed railway transportation, in particular to a method for automatically eliminating accumulated ice at the bottom of a motor train in the running process of a high-speed motor train unit. The method is suitable for high-speed rails and motor trains. The method can automatically eliminate accumulated ice at the bottom of the motor train in the running process of the high-speed motor train unit in cold seasons. The main function is to automatically clean up accumulated ice at the bottom of the motor train under the state of not parking or limiting speed; more importantly, it is avoided that water vapor or the like is condensing at the bottom of the motor train in the cold and accumulated ice is generated. According to the technical scheme, a temperature detection device unit detects the temperature at the bottom of the motor train, a control circuit gives instructions one by one according to the different temperature values obtained through detection, and a temperature control device unit is started and carries out temperature rise actions of different amplitudes on needed portions respectively. The running safety index of the high-speed motor train unit in winter is increased; the running speed and punctuality of the motor train are improved.
Description
Technical field
The present invention relates to railway transportation, relate to high speed railway, relate to Train operation control system CTCS (Chinese Train Control System) and onboard subsystem thereof and ground subsystem, relate to train overspeeding protection ATP(Automatic Train Protection), relate to temperature-control circuit and peripheral equipment that a kind of micro controller system is main body, relate to a kind of software-programming languages, relate to a kind of electric heating transition material and device, particularly a kind of high ferro motor train unit run in way imperial car prodelta clay ice method that automatically disappears.
The present invention is applicable to high ferro and motor-car, and being also applicable to take electric locomotive as the general fast passenger train of traction power.
Background technology
At present, the running state of Chinese high ferro and motor-car is such: every winter cold period, the moving velocity of (especially avenging sky) high ferro and motor-car all wants speed limit, that is to say Reduced Speed Now.This steam, droplet etc. because of snowing, in air condenses with flying dust, can condense upon bottom the train of running at high speed gradually---the particularly place such as car body EEF bogie, toilet waste collector, thus form accumulated ice.And along with time lapse, these accumulated ice can be more poly-thicker, even form ice and stick together.This accumulated ice or ice stick together and may fall because being given a shock at any time.If accumulated ice just in time falls on rail level signalling set, then not only can pound damage equipment, even can cause the misoperation of rail level signalling set, serious threat traffic safety.Especially northern areas, this kind of phenomenon is more outstanding.
It can thus be appreciated that happen cold period in winter, high ferro and motor-car often speed limit travel, and real genus bows to necessity.Deceleration object is the car body vibration amplitude caused because of high-speed cruising to reduce train, reduces and avoids accumulated ice ice to stick together generation resonance effects, thus guarantee driving safety.
In addition, in inspection and repair shop, when every day carries out daily service maintenance to high ferro motor train unit, cleaning car prodelta clay ice method at present, what often adopt is beat with waddy, makes it loosen and falls.This kind of method not only efficiency is low, also easily causes damage to car body.
Summary of the invention
The deficiencies in the prior art in view of the above,
technical matters to be solved by this invention is,there are provided one and meet cold season, high ferro motor train unit run in way imperial car prodelta clay ice method that automatically disappears.Described radical function has be run in way at two: one, not stopping, not under speed limit state, automatically removes existing accumulated ice bottom train; More importantly defend steam etc. to meet cold condensation bottom car and produce accumulated ice.
The existing full ripe electric heating transformation applications technology of described support and material, attain standby perfect electronics technology and software-programming languages by current, achieve and meet cold season, high ferro motor train unit are being run at high speed in way, and disappear imperial car prodelta clay ice automatically.
described beneficial effect mainly contains:1. add high ferro motor train unit winter driving safe in operation index; 2. can accomplish not speed limit, few speed limit, or reduce reduction of speed amplitude, thus improve train running speed; 3. can improve train punctuality rate; 4. improve the specific train time passes through density.
In addition, describedly following essential condition can be met completely: 1. do not destroy the existing streamlined structure of high ferro motor train unit; 2. device stability is high, and technology maturation is reliable; 3. not with existing onboard system and filled software conflict; 4. structure is simple, is easy to install, and is easy to manufacture, and portable high, with low cost; 5. durable in use, resistance to corrosion is good; 6. integral structure performance is little, not easily aging by temperature traverse.
the technical solution adopted for the present invention to solve the technical problems is:

Described method comprises following implementation step:
(1) first multi-point detected temperatures T is carried out by temperature detection device unit to bottom car, according to detecting the different numerical value of the temperature T obtained, assign instruction one by one by control circuit, start corresponding temperature regulating device unit, respectively to needing position to carry out the different intensification action of amplitude at the bottom of car;
(2) if T >=10 DEG C detected, be judged as true, then directly enter readiness for action, this end that circulates; Otherwise enter step (3) or step (4);
(3) if 5 DEG C≤T < 10 DEG C, then start control temperature unit 1, enter automatic mode except accumulated ice, otherwise enter step (4);
(4) if T < 5 DEG C, there are 2 kinds of deicing modes selective: default conditions enter automatic mode, start control temperature unit 2 and remove accumulated ice, otherwise enter step (5);
(5) if select manual mode, then program can start control temperature unit 1 and 2 simultaneously, carries out efficiently removing accumulated ice fast;
(6) step (2) is returned;
(7) it should be noted that, above-mentioned temperature is set to several threshold interval (T < 5 DEG C, 5 DEG C≤T < 10 DEG C, T >=10 DEG C), just set to describe convenient, it is interval that device in kind not sticks to this temperature threshold, may adjust to some extent as required, also can be divided into more small threshold interval to temperature threshold interval; In like manner, temperature regulating device unit also not sticks to 2, refinement can be adjusted to several and deposit.
Feature of the present invention is also, temperature at the bottom of the car detected, is set to several temperature threshold interval, and corresponding one or the several temperature regulating device unit of each threshold interval, as required to taking the mode of different capacity to heat up between each threshold value respectively.
