Abstract
The invention discloses a train overhead contact system hard spot detection device based on acceleration detection and the Bluetooth technique. The device comprises a micro processor, an ADC, an MEMS acceleration sensor, an EEPROM storage chip, a clock chip, a temperature sensor, a Bluetooth receiving and dispatching module, a power supply management module and the like. The device is small in size, low in weight and capable of being directly and fixedly installed on a pantograph support; the MEMS three-axis acceleration sensor is embedded in the device to collect acceleration data of the pantograph support; the micro processor carries out preset hard spot acceleration threshold value operation and judges whether to output hard spot trigger signals and start storage, and the acceleration threshold value can be increased and decreased in a Bluetooth communication mode. Due to the fact that the MEMS three-axis acceleration sensor is used for carrying out pantograph hard spot detection, reliability of pantograph hard spot detection is substantially improved, and accuracy of daily hard spot inspection and first-aid repair and maintenance efficiency are improved.
Description
Technical field
The present invention relates to train contact network hard spot detection field.
Background technology
Along with improving constantly of China's train speed per hour, it is important all the more that the security of train pantograph seems.Contact net hard spot is the persistent ailment that all the time affects train traction pantograph net current carrying quality.Contact net hard spot is that locomotive is in the time that high-speed cruising passes through, the place that the contact force of pantograph and contact net changes suddenly because of external force, it is a kind of physical phenomenon that has threat, it can destroy the normal contact between bow net and be flowed, accelerate abnormal wear and the impact infringement of wire and pantograph pan, spark or arcing are caused in these positions of being everlasting, and even damage osculatory and pantograph.
And the current stage, the mode that train bow net hard spot pick-up unit obtains contact net hard spot be mostly by installing according to indoor test acceleration hard spot threshold values and the spring leaf of preset clearance running into while being more than or equal to the hard spot of correspondingly setting threshold values, make its closure and contact point form loop by external force and trigger hard spot signal, or utilize single-axis accelerometer to carry out single point and detect and judge hard spot to acceleration threshold values.But all existing hard spot, above two kinds of bow net hard spot detection modes detect inaccurate, easy false triggering, the situation that can not trigger maybe.Equipment Inspection consistency of performance is poor, acceleration threshold values is difficult for change, waits shortcomings.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of train contact network hard spot pick-up unit based on acceleration detection and Bluetooth technology.Can increase substantially hard spot detection accuracy, effectively reduce personnel's workload, promote daily hard spot investigation, repairing accuracy and maintenance efficiency.
The technical solution adopted in the present invention is: comprise microprocessor, ADC analog to digital converter, MEMS acceleration transducer, EEPROM storage chip, clock chip, temperature sensor, bluetooth transceiver module, power management module, wherein microprocessor is connected with ADC analog to digital converter, MEMS acceleration transducer, EEPROM storage chip, clock chip, temperature sensor, bluetooth transceiver module, power management module respectively.When system operation, built-in MEMS 3-axis acceleration sensor carries out acceleration information collection to bow net support, microprocessor is preset the computing of hard spot acceleration threshold values, judge whether to export hard spot trigger pip and start storage, acceleration threshold values can increase and decrease setting by Bluetooth communication mode.The output of hard spot signal can be analog switch amount signal or acceleration value (ASCII character).In system operational process all reach threshold values trigger require acceleration information and running state parameter as; In machine, voltage, temperature etc. all can be recorded in eeprom chip.
Compared with prior art, the invention provides a kind of train contact network hard spot pick-up unit based on MEMS acceleration transducer.Can increase substantially hard spot detection accuracy, effectively reduce personnel's workload, promote daily hard spot investigation, repairing accuracy and maintenance efficiency.
