Detailed Description
The architecture of the battery warehousing monitoring device in this embodiment is shown in fig. 1, and includes an upper computer, a plurality of switches, a plurality of gateways, and a plurality of sensor units. The upper computer, the switch, the gateway and the sensor unit are sequentially connected in a tree-shaped mode.
Referring to fig. 2, the warehousing space for storing batteries applied to the battery warehousing monitoring device in the embodiment may be divided into three levels, including a first-level warehousing unit, a second-level warehousing unit and a third-level warehousing unit. In this embodiment, the first-stage storage units may be a plurality of rows into which the whole storage space is divided, the second-stage storage units may be rows into which one row is divided, and the third-stage storage units may be bays into which each row is divided.
In this embodiment, referring to fig. 1 and fig. 2, the upper computer branches a plurality of interfaces through the first-stage switch to be connected to each second-stage switch, and each second-stage switch can be extended to be connected to a plurality of gateways. In this embodiment, the architecture of the gateway used is as shown in fig. 3. Each gateway is respectively responsible for one row, specifically, each gateway expands a plurality of bus interfaces, each bus interface on the same gateway is respectively responsible for one row, a plurality of sensor units connected with one bus are installed in each compartment of the row, so that the storage state of the battery stored in the compartment is detected, and then the storage state is uploaded to an upper computer through the gateway, the secondary switch and the primary switch in sequence.
In this embodiment, referring to fig. 4, each sensor unit includes a controller, a smoke detector, a heat detector, an alarm, and a bus interface. The controller is respectively connected with the smoke detector, the heat detector, the alarm and the bus interface. In this embodiment, the bus interface is a 485 bus interface, which can perform conversion of a communication protocol, that is, the bus interface is externally connected to the gateway through a 485 serial communication protocol, and the bus interface is internally connected to the controller in the sensor unit. The sensor unit detects smoke in the compartment through the smoke detector and detects abnormal heating in the compartment through the heat detector, that is, the storage state of the battery in the embodiment may include whether the battery generates smoke and whether the battery generates abnormal heating. When the battery generates smoke or generates heat abnormally, the sensor unit can upload data to an upper computer for alarming after detecting the smoke or the heat abnormally, and can also alarm light or sound through an alarm in the sensor unit.
In this embodiment, an optional manner is to provide an address code memory in the sensor unit, where a unique and unchangeable address code is stored in the address code memory in a solidified manner, so that the upper computer can perform addressing access on the sensor unit through the address code. The arrangement sequence in the storage space of the sensor unit can be set according to the address code of the sensor unit, and then the polling time sequence of the upper computer is formulated according to the address code of the sensor unit. The polling time sequence of the upper computer determines the access sequence of each sensor in the access of each wheel to each sensor unit. The host computer may perform polling every 2 minutes or other time to track the battery storage status of the compartment in which each sensor unit is installed. In this alternative mode, the address code of each sensor unit is fixed and unchangeable, and therefore unless the rule for setting up the polling time sequence changes, the sequence of accessing each sensor unit in the polling time sequence is fixed and unchangeable, and the upper computer can judge whether accidents such as battery self-heating, spontaneous combustion or explosion happen to each compartment according to the storage state read by accessing each sensor unit.
In this embodiment, another optional manner is to provide a pseudo-random number generator in the sensor unit, where the pseudo-random number generator generates a pseudo-random number as an address code of the sensor unit by timing and using a current timing value as a seed, so that the upper computer can perform addressing access on the sensor unit through the address code. The arrangement sequence in the storage space of the sensor unit can be set according to the address code of the sensor unit, and then the polling time sequence of the upper computer is formulated according to the address code of the sensor unit. The polling time sequence of the upper computer determines the access sequence of each sensor in the access of each wheel to each sensor unit. The host computer may perform polling every 2 minutes or other time to track the battery storage status of the compartment in which each sensor unit is installed. In the optional mode, the address code of each sensor unit is changed at regular time or irregular time, and the upper computer can judge whether accidents such as self-heating, spontaneous combustion or explosion of the battery occur in each compartment or not according to the storage state read by accessing each sensor unit; because under normal conditions, the address code of each sensor unit is changed at regular time or irregular time, the upper computer can determine whether the sensor unit works normally by scanning whether the address code of each sensor unit changes, so that whether accidents happen to a compartment where the sensor unit is located is indirectly judged, and at the moment, the upper computer can not communicate with each sensor unit in a polling mode. Under the condition of connecting through wireless thing networking mode between host computer, switch, gateway and the sensor unit, avoid too much polling can the using electricity wisely to strengthen battery storage monitoring device's duration.
The upper computer can directly judge whether the compartment for storing the battery is abnormal or not through the storage state obtained by the polling sensor unit; the upper computer can indirectly judge whether the compartment for storing the battery is abnormal or not by detecting the change of the address code of the sensor unit. If the upper computer judges that the compartment has the abnormity, an alarm can be given, and the content of the alarm can comprise the number of the compartment with the abnormity or the number or the address code of the installed sensor unit, so that a technician can quickly determine which compartments have the abnormity.
In some embodiments, a section of a bus connecting between the sensor unit and the gateway may be made using a heat-fusible conductive medium, thereby forming a thermal fuse section on the bus, and the thermal fuse section may be disposed within the compartment. When accidents such as self-heating, spontaneous combustion or explosion of the battery occur in the compartment, the thermal fusing section is heated and fused, the connection between the sensor unit and the gateway is cut off, and the sensor unit and the gateway can be protected. At the moment, the upper computer can find that the sensor unit is disconnected in time no matter whether a polling mechanism is set or not, so that the fault is accurately identified and positioned.
