Abstract
The utility model provides a drying oven temperature monitoring system, solving the problem that at present each drying oven is provided with one temperature monitoring device so that monitoring the temperature of all the drying ovens requires observing a temperature display device on each drying oven successively and each temperature display device does not display the historical temperature. The drying oven temperature monitoring system is characterized in that the output ends of a plurality of identical signal pickup assemblies access an interface inside an industrial personal computer through connection in parallel; each signal pickup assembly is formed by two temperature sensors, an interface box and a proximity sensor; the two temperature sensors and the interface box are arranged in each drying oven; the proximity sensor is arranged at 3 to 5mm being apart from the outside of each drying oven; the output ends of the two temperature sensors are respectively connected with the input ends of two transmitters; the output ends of the two transmitters are connected with a 485 interface of a multi-serial-port card successively; and the output end of the proximity sensor is connected with an I/O interface. The drying oven temperature monitoring system has the advantages of assembling the temperature monitoring of all the drying ovens into one temperature monitoring system, and being able to monitor the time and the number for opening and closing the door of each drying oven.
Description
Technical field
The utility model relates to a kind of system that monitors the drying box temperature.
Background technology
Drying box is a kind of device that is used for the starting material pyroprocessing.Establish a device for detecting temperature in each drying box at present; Device for detecting temperature comprises two temperature sensors, temperature indicating device etc.; One of them temperature sensor is arranged on depths in the drying box (to call first temperature sensor in the following text), and another temperature sensor is arranged in the case near chamber door place (to call second temperature sensor in the following text), and they all are integrated on the drying box; Be that each drying box has an independently device for detecting temperature, do not get in touch with other drying box.Usually there are several drying boxes in each pyroprocessing workshop, and monitor temperature then need be observed the temperature indicating device on each drying box, inconvenience successively; Secondly, the temperature indicating device on each drying box only shows current temperature, does not show historical temperature, does not more have the time keeping that drying box opens the door, closes the door.To sum up, bring many inconvenience to use.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model provides a kind of drying box temperature monitoring system that can avoid above-mentioned deficiency.
The purpose of the utility model is achieved in that several same signal pickup assembly, and their output terminal parallel connection inserts the inner interface of an industrial computer; Each signal pickup assembly by first and second temperature sensors that are provided with in each drying box, interface box and each drying box outdoors the inductance type proximity transducer that is provided with of 3-5mm place form; Interface box the is inner integrated first and second intelligent isolating transmitters, a 24V Switching Power Supply, the output terminal of first and second temperature sensors is connected on the input end of the first and second intelligent isolating transmitters respectively; The output terminal of two intelligent isolating transmitters is connected on 485 interfaces of the inner multi-serial-port card of industrial computer successively, and the output terminal of inductance type proximity transducer is connected on the inner I/O interface of industrial computer.The signal of three sensor outputs of each drying box is presented at software master interface after the industrial computer data processing.This software also possesses functions such as data storage, historical data are checked, printing, audio alert.
Compared with prior art; The good effect of the utility model is: the temperature monitoring of the drying box that it is all with a workshop even enterprise is formed a temperature monitoring system; Can monitor the Current Temperatures of all drying boxes at the three unities simultaneously; Moreover can also check historical data, realize printing functions such as change curve and audio alert; Secondly owing to be provided with the inductance type proximity transducer in the 3-5mm place outdoors at each drying box, it can also monitor time or the number of times that drying box opens the door, closes the door; It also can be newly-increased drying box device for detecting temperature and has reserved interface at last, can be incorporated into the power networks increasing the drying box device for detecting temperature newly at any time.
Description of drawings
Fig. 1 is the electrical schematic diagram of the utility model.
Embodiment
Several same signal pickup assembly 1, their output terminal parallel connection inserts the interface of an industrial computer 2 inside; Each signal pickup assembly by first temperature sensor 11 of 14 li settings of each drying box and second temperature sensor 12, interface box 15 and each drying box outdoors the inductance type proximity transducer 13 that is provided with of 3-5mm place form; Interface box the is inner integrated first intelligent isolating transmitter 151 and the second intelligent isolating transmitter 152 and a 24V Switching Power Supply; First temperature sensor 11 is connected on the input end of the first intelligent isolating transmitter 151, and the output terminal of second temperature sensor is connected on the input end of the second intelligent isolating transmitter 152; The output terminal of two intelligent isolating transmitters is connected on 485 interfaces of the inner multi-serial-port card of industrial computer successively, and the output terminal of inductance type proximity transducer is connected on the inner I/O interface of industrial computer.The signal of three sensor outputs of each drying box is presented at software master interface after the industrial computer data processing.This software also possesses functions such as data storage, historical data are checked, printing, audio alert.
Said first and second temperature sensors are selected the Pt100 platinum resistance temperature sensor for use.
