Background technology
In recent years, as technological progress and national policy are supported, intelligent grid and new-energy automobile are quickly grown, accordingly
Component functional requirement also constantly changes.Capacitance applied to flexible DC power transmission, which is unwrapped, to be begun to use longer life expectancy, and performance is more excellent
Thin-film capacitor.Large bulk capacitance bag is generally by up to a hundred, or even thousands of a capacitor core connection in series-parallel compositions.During use, electricity
Hold fuse temperature to be generally not much different, if wherein some capacitor core fever is abnormal, immediately should cut the capacitance bag from system
Remove, otherwise can there are huge security risk.Equally battery pack as electric automobile Primary Component, in structure also with above-mentioned electricity
It is similar to hold bag, and internal temperature branch inequality also brings along security risk.Therefore a kind of multichannel thermometric simple in structure is developed
System, carries out capacitor internal fuse temperature monitoring in real time and becomes necessary to.
Road temperature sensors up to a hundred are generally required in view of application scenario, conventional thermoelectric occasionally Thermistor Temperature Measurement method can be led
Mass data line is caused to draw.In space, limited occasion carries out wiring to these lead-out wires becomes infeasible.
The content of the invention
The purpose of the present invention is to propose to a kind of multichannel temperature to monitor system, existing in the prior art to solve the problems, such as.
The present invention can be achieved by the following technical programs：
A kind of multichannel temperature monitors system, including temperature sensor, temperature sensor bus, be wirelessly transferred collection plate,
The webserver, administrator's PC machine, the temperature sensor bus port, which connects, is wirelessly transferred collection plate, and temperature data passes through described
The GPRS module for being wirelessly transferred collection plate is wirelessly transferred, and data interaction, the network clothes are carried out with the webserver
Device be engaged in by processed data transfer to the administrator's PC machine being connected with internet.
Wherein, described to be wirelessly transferred 4 bus ports of collection plate point, each port connects No. 256 sensors, i.e. connection altogether
No. 1024 sensors, the address ID of No. 1024 sensor be stored in advance in it is described be wirelessly transferred in collection board chip, during work
The collection plate that is wirelessly transferred successively is polled each ID inquiry, and only corresponding sensor returns temperature number in bus
According to.
Wherein, the temperature sensor uses DS18B20；The temperature sensor bus uses soft PCB, all temperature
Sensor is connected in temperature sensor bus using parallel form.
Wherein, the webserver realizes data acquisition and processing (DAP) using cloud service technology.
The present invention selects digital temperature sensor DS18B20, and the sensor is excellent with small, strong antijamming capability etc.
Point, and unibus structure can be used.In a piece bus can a sensors up to a hundred in parallel, dramatically reduce wiring difficulty, reduce
Manufacture risk.The temperature monitoring system that we develop, supports 1024 road temperature-monitoring functions.Simple wire laying mode, far more than
The thermometric port number that general measure mode is supported.Compact hardware configuration, makes the temp measuring system be very suitable for flexible direct current defeated
Capacitance bag, batteries of electric automobile etc. need multichannel thermometric occasion.The present invention reduces temperature sensor wiring to greatest extent
Difficulty, for the application scenario of spaces compact, can save space, reduce assembly difficulty.In soft straight capacitance and automobile batteries etc.
The occasion of a large amount of temperature measuring points is needed, which provides most suitable solution.
