Description
Technical field
The utility model relates to a kind of electric battery detection system and testing circuit thereof and collector, the electric battery detection system, testing circuit and the collector that use in the ice storing time field particularly on railway locomotive and passenger vehicle.
Background technology
As the main carriers of railway traffic---locomotive and passenger vehicle; particularly on locomotive, accumulator is the accessory power supply of direct supply; illumination when providing shutdown, diesel locomotive start; electric locomotive is before rising bow and when thyristor voltage stabilized source breaks down; powered to locomotive control circuit by battery pack, be all furnished with a large amount of accumulators.When locomotive operation is to certain milimeter number, maintenance personal will be measured by multimeter successively, and under detecting the electric voltage exception situation finding to exist, carry out fast dismantling and remove, replace, install, and then detect, locomotive could put into operation again.
The mode of this traditional detection battery tension belongs to pure manpower and measures, and wastes time and energy, inefficiency, and undetected, and false retrieval happens occasionally.
In ice storing time field, also there is the scheme of more automatic measurement.Such as configure a collector (or being called acquisition module) to each cell, each collector is wired to the both positive and negative polarity of corresponding cell, to detect cell voltage; Meanwhile, each collector also needs to be wired to on-site control device, to realize the data of collection to transfer out.Such as application number be 201110322544.6 Chinese patent application " a kind of electric vehicle storage battery pack wireless detection management system " be exactly so a kind of scheme: for detecting voltage, the temperature of whole each accumulator of battery pack, for each accumulator increase by one detect from check-out console, be made up of from check-out console chips such as MCU, AD conversion, temperature sensors.By the mode of serial communication, each detection data acquisition from check-out console is got up by a main check-out console, be then sent to server by the mode of wireless transmission.In the program, be namely equivalent to collector from check-out console, namely main check-out console is equivalent to on-site control device.

This scheme is that the digital voltmeter of the mode utilizing MCU, AD conversion detects cell voltage.Also existing in prior art utilizes the mode of analog voltage table to detect the mode of voltage.If this uses analog voltage table in such scheme, check-out console volume can be larger, and economy may be poorer.
Reality when mounted, still relates to many wiring: be the lead-in wire that collector gathers cell voltage on the one hand; Usual each collector just needs one or two, for connecting battery plus-negative plate ear.Be on the other hand the lead-in wire of collector and on-site control device, usual each collector connects on-site control device respectively, and lead-in wire is a lot, and long (with the distance dependent of collector with on-site control device), cause lead-in wire complexity, execute-in-place complexity.
In addition, in the prior art, detect cell voltage adopt acquisition module (as in 201110322544.6 from check-out console) be sticked on battery, to realize fixing, and also need the enterprising horizontal electrical signal collection of lug being wired to battery, voltage sampling form is comparatively clumsy simultaneously.
In sum, mainly there are three technical matterss in prior art: one, and have electric battery to measure the device needed more, cost is higher; Two, the mode of being connected and fixed needs to fix, wiring, installs loaded down with trivial details, easily occurs misconnection, misconnection, occur getting loose or coming off in locomotive (passenger vehicle) operational process.Three, voltage sampling form is clumsy.
