Abstract
The utility model relates to the technical field of electrical control, and discloses a temperature detection disconnection closed loop device comprising a time control unit, a temperature measurement unit, a comparator unit and a controller unit which are sequentially connected, and a power switch unit and a locking unit which are connected with the controller unit. The temperature detection disconnection closed loop device adopts timing temperature measurement, respectively compares the measured temperature value with a set temperature value or a highest value upon disconnection, so that tripping or locking alarm is determined in real time, and the problem that due to the false phenomenon that an on-site temperature measurement element is disconnected, so that the temperature suddenly reaches the maximum range, the error shut-down is caused to affect production continuity is prevented.
Description
Technical field
The utility model relates to the Electrical Control Technology field, particularly relates to a kind of temperature detection broken string closed-loop device.
Background technology
In the large-scale production line production equipment of industries such as iron and steel, chemical industry, because the field apparatus environment is comparatively complicated, temperature point breaks easily and is subjected to the interference of other signals, causes the chain misoperation of temperature, make equipment mistakenly stop machine, thereby influence is produced.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to overcome the temperature that causes because of on-the-spot thermometric broken string to arrive the highest false phenomenon of range suddenly, thus the continuity that causes mistakenly stop machine and influence to produce.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of temperature detection broken string closed-loop device, and it comprises:
Temperature measurement unit connects comparator unit, and described temperature measurement unit sends measured temperature value to described comparator unit;
Comparator unit connects controller unit and described temperature measurement unit, and described comparator unit compares the temperature value of described temperature measurement unit transmission and the threshold value of self, and sends the result who is compared to described controller unit;
Controller unit connects described comparator unit, and described controller unit receives the comparative result that described comparator unit transmits, and sends control command;
Power switch unit and locking alarm unit all are connected with described controller unit, receive the control command that described controller unit sends.
Said temperature detects in the broken string closed-loop device, also comprises: time control unit, be connected with described temperature measurement unit, and described time control unit is controlled described temperature measurement unit and is regularly carried out temperature survey.
(3) beneficial effect
In the temperature detection broken string closed-loop device that technique scheme provided; adopt temperature survey regularly; and with measured temperature value respectively with desired temperature or the broken string peak compare; thereby determining tripping operation or locking in real time reports to the police; avoid because of on-the-spot temperature element broken string; make temperature reach the highest false phenomenon of range suddenly, cause the mistakenly stop machine, to influence the production continuity.
Description of drawings
Fig. 1 is the schematic diagram of the temperature detection broken string closed-loop device of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 shows the schematic diagram of the temperature detection broken string closed-loop device of the utility model embodiment, it comprises: the time control unit of Lian Jieing successively, temperature measurement unit, comparator unit, controller unit, and power switch unit that all is connected and locking unit with controller unit, time control unit certain hour at interval sends signal to temperature measurement unit, make temperature measurement unit carry out temperature survey, temperature measurement unit sends the temperature value that records to comparator unit, temperature value that comparator unit is measured with temperature measurement unit and the desired temperature that self sets compare, if temperature value is no more than set point, then belong to normal range (NR); If temperature value surpasses set point, then this temperature value and broken string peak are compared, if this temperature value equals the peak that breaks, comparator unit sends comparative result to controller unit, controller unit control locking is also sent alarm signal; If this temperature value is not equal to the broken string peak, comparator unit sends comparative result to controller unit, and controller unit control power switch unit time-delay 1s trips.Power switch unit is set to delay time, and 1s trips is can not suddenly change according to temperature, differs under the 30 degree situations at set point and broken string peak, should not reach broken string peak experience 1 second time.
As can be seen from the above embodiments; the utility model embodiment is by adopting temperature survey regularly; and with measured temperature value respectively with desired temperature or the broken string peak compare; report to the police thereby determine tripping operation or locking in real time, avoid making temperature reach the highest false phenomenon of range suddenly because of on-the-spot temperature element broken string; cause the mistakenly stop machine; to influence the production continuity, can improve the running rate of equipment, reduce production costs.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
Claims (2)
