Abstract
The embodiment of the invention provides a method for rewriting a transponder message. The method comprises the following steps of: receiving a first transponder message which is to be written into a transponder to be rewritten; reading a first key variable in the first transponder message; reading a second key variable in a second transponder message which exists in the responder to be rewritten; and comparing that whether the first key variable with the second key variable are consistent or not, if yes, writing the first transponder message into the responder to be rewritten. According to the method, a step of monitoring the transponder message writing is additionally arranged, so that the transponder message can be effectively prevented from being written into the non-corresponding transponder, moreover, the checking and rewriting work of the transponder message is completed through a computer, the engineering technicians are not needed, thus, the possible risk that the engineering technicians do not write the transponder message into the corresponding transponder can be reduced, and the accuracy of on-site transponder message rewriting is ensured. In addition, the embodiment of the invention further provides a device for rewriting the transponder message.
Description
Technical field
The present invention relates to railway signal technology field, relate to a kind of transponder message Improvement and device in particular.
Background technology
Transponder (Balise) is a kind of point type equipment transmitted to train information for ground, and its main application provides reliable terrestrial information to train control on board equipment.Each transponder (or transponder group) has a numbering, and this numbering is unique in china railway scope.The end place out of the station at block section entrance or station is located at by transponder, when train is by transponder, the transponder message that transponder transmission stores self or the transponder message that LEU (LEU) transmits, provide the information such as train location, line slope, speed to train control on board equipment.
Transponder re-writing device, as the readwrite tests equipment of transponder message, in the process that transponder device production test and field adjustable are safeguarded, is absolutely necessary.
Transponder to the information such as train location, line slope, speed that train control on board equipment provides by after safe coding as transponder message, by transponder re-writing device write transponder, once transponder write transponder message, transponder position on the line is just determined, and is unique.During on-the-spot rewriting transponder message, if the transponder message of non-corresponding to be write the transponder of specifying, the location of train meeting read error when passing through above this transponder, line information, and then affect safety and the efficiency of driving, stopping in emergency or advancing rashly of train may be caused time serious.
At present, the method of rewriting transponder message conventional on railway signal is, field engineering technical staff reads the transponder message of assigned address, and artificially contrast with transponder message data list, confirm unanimously, then on the application interface of transponder re-writing device, carry out the rewriting work of transponder message.In actual applications, because engineers and technicians people is for checking transponder message data and change transponder message on transponder re-writing device, therefore, may exist not by transponder corresponding for the transponder message write of specifying when rewriting transponder message, transponder is caused to read location, the line information of mistake, the safety of impact driving and efficiency.
Summary of the invention
In view of this, in order to solve the inaccurate problem of transponder message that people in prior art reads for the transponder checked and change transponder message and cause, on the one hand, provide a kind of transponder message Improvement, technical scheme is as follows:
Comprise:
Receive the first transponder message preparing to write and wait to rewrite transponder;
Read the first key variables in described first transponder message;
Read the second key variables in the second transponder message, described second transponder message is waited to rewrite the message in transponder described in being present in;
Whether the first key variables described in comparison are consistent with described second key variables, if unanimously, then wait to rewrite transponder described in described first transponder message write.
Preferably, in above-mentioned transponder message Improvement, described first key variables and described second key variables comprise:
The position N_PIG of transponder in transponder group, packet accouter M_MCOUNT, area number NID_C, transponder identification number NID_BG, and the number of transponders N_TOTAL comprised in transponder group.
Preferably, in above-mentioned transponder message Improvement, also comprise:
Retaking of a year or grade checking message;
Judge the correctness of described checking message, if described checking message is correct, then described first transponder message writes successfully.
On the other hand, additionally provide a kind of transponder message re-writing device,
Comprise message receiving element, the first reading unit, the second reading unit, and comparing unit;
Described message receiving element, for receiving the first transponder message preparing to write and wait to rewrite transponder;
Described first reading unit, for reading the first key variables in described first transponder message;
Described second reading unit, for reading the second key variables in the second transponder message, described second transponder message is waited to rewrite the message in transponder described in being present in;
Described comparing unit, whether consistent with described second key variables for the first key variables described in comparison, if unanimously, then described first transponder message is write described transponder.
Preferably, in above-mentioned transponder message re-writing device, described first key variables and described second key variables comprise:
The position N_PIG of transponder in transponder group, packet accouter M_MCOUNT, area number NID_C, transponder identification number NID_BG, and the number of transponders N_TOTAL comprised in transponder group.
Preferably, in above-mentioned transponder message re-writing device, retaking of a year or grade unit and judging unit is also comprised:
Described retaking of a year or grade unit, retaking of a year or grade checking message;
Described judging unit, judges the correctness of described checking message, if described checking message is correct, then described first transponder message writes successfully.
The embodiment of the present invention adds the monitoring step of transponder message write, namely judge to prepare to write wait the transponder message rewriting transponder key variables whether with wait that the key variables rewriting transponder message in transponder are identical, the write operation of transponder message is carried out again after identical, it can effectively prevent transponder message from writing not corresponding transponder, and, transponder message check and rewriting work is all completed by computer, eliminate engineers and technicians, thus really reduce the risk that may exist when engineers and technicians rewrite transponder message at the scene and will message do not specified to write corresponding transponder, ensure that on-the-spot accuracy of rewriting transponder message, avoid due to transponder message information mistake, the driving accident caused.
