The coil of the temperature of a heating plate, the temperature control modules and solid-state relay connects, and hands over temperature acquisition polling module
It connects, the PLC controller and temperature control modules and host computer interconnect.
It further, further include touch screen, the touch screen and PLC controller interconnect.
Further, the temperature sensor includes p-type platinum resistance and K-type thermocouple.
A kind of control system and control method for power battery oven temperature, comprising the following steps:
(41) it is equipped with a heating plate in the face up and down of baking box and below, every group of heating plate is connected with temperature sensing
Device；
(42) it acquires the temperature of each heating plate by temperature acquisition polling module and temperature is sent to PLC and control mould
Block；
(43) each group temperature data received is compared by PLC controller module, takes out maximum value, minimum value, and
Temperature averages and temperature deviation are calculated, above-mentioned data are uploaded to host computer, touch screen, and controls solid-state relay conducting
Turn off the heating of frequency real-time control；
(44) operation is compared to each group of data of acquisition in PLC control module, while the result of acquisition and comparing fortune
Temperature parameter after calculation is uploaded to host computer and touch screen, and operator is monitored and is modified by host computer or touch screen.
As shown from the above technical solution, the control system and controlling party of the present invention for power battery oven temperature
On the one hand method is able to carry out and is divided into modularization to baking temperature and individually controls, it is more reasonable to design, simpler to be easy calibration；It is another
Temperature patrol inspection is added in aspect and temperature collection module reaches whole real-time monitoring temperature and improves safety and reliability.The present invention
Maximum value in 9 pieces of heating plates of display is acquired in real time by host computer after PLC controller operation relatively and touch screen, and minimum value is simultaneously counted
Calculate the temperature deviation value of 9 groups of heating temperature data, temperature averages, then using the above-mentioned displays temperature parameter of PLC operation
Value, if not within the set range if adjust the temperature data of corresponding heating plate in real time, reach more intelligent and precisely control temperature
Spend uniformity；Battery baking temperature consistency is preferably promoted to allow, improves battery quality performance.
Detailed description of the invention
Fig. 1 is control system figure of the invention；
Fig. 2 is the scheme of installation of heating board of the invention in baking box.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
A kind of power battery oven temperature control system as shown in Figure 1:, including the control of temperature acquisition polling module 4, temperature
Module 5, PLC controller 6, host computer 7, solid-state relay 9 and baking box, be equipped on each panel in baking box one plus
Hot plate, and it is connected with temperature sensor 2 on hot plate, which passes through the acquisition baking of temperature sensor 2
Temperature in case in each heating plate, temperature control modules 5 are connect with the coil of solid-state relay 9, and with temperature acquisition inspection
Module 4 interconnects, and the PLC controller 6 and temperature control modules 5 and host computer 7 interconnect.
As shown in Fig. 2, in oven interior position up and down and above the heating plate 1 of subsequent 9 pieces of independently installed control
Temperature sensor K-type thermocouple temperature sensor p-type platinum resistance is installed, different heating is acquired by temperature sensor 2 respectively
Plate temperature, K-type thermocouple totally five and are installed and are used to measure space temperature in baking oven on hot plate；P-type platinum resistance totally four
It is a to be mounted on the temperature for being used to measure partial points in baking oven above heating plate；In the acquisition inspection in real time of temperature acquisition polling module 4
