The temperature sensor is provided with the cascade interface and the dip switch, and can realize cascade connection of a plurality of the temperature sensors and then connection with the monitoring equipment, the various temperature sensors are distinguished from each other by the address set by the dip switch, and the control over a plurality of the temperature sensors can be achieved only by arranging an interface on the monitoring equipment, thus saving the cost.
Description
Technical field
The present invention relates to a kind of temperature sensor.
Background technology
Temperature sensor in the existing machine room all is to detect place's temperature to issue watch-dog by interface.Watch-dog need carry out temperature detection to a plurality of positions in the machine room.Watch-dog need be provided with a lot of interfaces and link to each other with different temperature sensor respectively, and this makes, and interface on the watch-dog is a lot, cost is high.
Summary of the invention
Technical matters to be solved by this invention is exactly in order to overcome above deficiency, to have proposed a kind of temperature sensor, reducing the cost of watch-dog.
Technical matters of the present invention is solved by following technical scheme:
A kind of temperature sensor, comprise thermal sensing element and controller, described thermal sensing element links to each other with controller, comprise subtending port and toggle switch, described subtending port links to each other with controller respectively with toggle switch, described subtending port be used for machine room in other temperature sensors or the machine room watch-dog be electrically connected, described toggle switch is used to be provided with the address of temperature sensor.
Also comprise display module, described display module links to each other with controller, is used for the address of displays temperature data and temperature sensor.
Described display module is a section-type LCD.
Also comprise alarm module, described alarm module links to each other with controller, and output alarm signal is to alarm module when temperature data exceeds preset range for controller, and described alarm module sends the indication of reporting to the police.
Described warning is designated as at least one in acoustic alarm and the light warning.
Described controller has sleep mode.
Described controller is at work T1 dormancy T2 time after the time, T2〉T1.
Described subtending port is the RJ45 interface.
Described temperature sensor is the machine room temperature sensor.
The beneficial effect that the present invention is compared with the prior art is: temperature sensor of the present invention is provided with subtending port and toggle switch, can realize linking to each other with watch-dog again after the cascade between a plurality of temperature sensors, distinguish mutually by the address of toggle switch setting between each temperature sensor, can realize monitoring as long as an interface is set on the watch-dog, save cost a plurality of temperature sensors.
Description of drawings
Fig. 1 is the structural representation of the temperature sensor of the specific embodiment of the invention;
Fig. 2 is the schematic side view of the temperature sensor of the specific embodiment of the invention;
Fig. 3 is the circuit theory synoptic diagram of the temperature sensor of the specific embodiment of the invention.
Embodiment
Also in conjunction with the accompanying drawings the present invention is described in further details below by concrete embodiment.
As shown in Figure 1, a kind of temperature sensor comprises thermal sensing element 6 and controller 5.Described thermal sensing element 6 links to each other with controller 5, and described thermal sensing element 6 to controller 5, can obtain the temperature data of detection place according to the output of the different temperatures in machine room relevant temperature signal after 5 pairs of processes temperature signal of described controller.Described thermal sensing element 6 can be thermistor or thermal diode or temperature-sensitive reactor or heat sensitive resonance instrument etc.
As shown in Figure 1, 2, 3, described temperature sensor also comprises subtending port 1 and toggle switch 4, and described subtending port 1 links to each other with controller 5 respectively with toggle switch 4.Described subtending port 1 be used for machine room in other temperature sensors or the machine room watch-dog be electrically connected, described toggle switch 4 is used to be provided with the address of temperature sensor.Toggle switch 4 can think that at closure state it is represented 1, can think that at opening state it represents 0.The number of described toggle switch 4 is decided as required, generally selects 6.Subtending port 1 on the described temperature sensor has two.Described subtending port can be the RJ45 interface.
A plurality of temperature sensors can link to each other by subtending port 1 and link to each other with watch-dog by subtending port 1.So only need to use 1 interface of watch-dog just can realize the many places temperature is monitored.The toggle switch 4 of each temperature sensor is set an address to self respectively, and each temperature sensor has the address of self simultaneously when the temperature data of self is issued watch-dog, and watch-dog can be distinguished different temperature sensors according to the address.But a plurality of temperature sensors of the present invention's cascade, when adopting the RS485 agreement as the cascaded communication agreement, but maximum 32 temperature sensors of cascade of the present invention.
As shown in Figure 1, 2, 3, described temperature sensor also comprises display module 2, and described display module 2 links to each other with controller 5, is used for the address of real-time displays temperature data and temperature sensor.This makes things convenient for the user to check the address of temperature data and temperature sensor.Described display module can be common LCD display.Described display module also can be section-type LCD, to save cost.
Shown in Fig. 1,3, described temperature sensor also comprises alarm module 3, and described alarm module 3 links to each other with controller 5, and output alarm signal is to alarm module 3 when temperature data exceeds preset range for controller 5, and described alarm module 3 sends the indication of reporting to the police.Described warning is designated as at least one in acoustic alarm and the light warning.The present invention can make the user find the position of reporting to the police as early as possible, faster unusual condition is positioned.
Described controller 5 has sleep mode.Particularly, described controller 5 is at work T1 dormancy T2 time after the time, T2〉T1.In working time T1, controller 5 control thermal sensing elements carry out temperature detection, controlled stage connecting port carry out temperature data report, control display module 2 shows corresponding informations and when temperature data exceeds preset range control warning module 3 send the indication of reporting to the police.Quit work in dormancy time T2 internal controller 5, to save power consumption.In dormancy time T2,, promptly enter the working time if controller 5 has received the activation signal that watch-dog sends then carried out work automatically.This can reduce the power consumption of temperature sensor of the present invention, and then after making a plurality of sensor series connection the requirement of power is reduced to minimum.
Temperature sensor of the present invention is well suited for using in machine room.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
