Description
Technical field
The utility model relates to a kind of flexible pavement heating pad wall (plate) of asphalt surface hot reproduction equipment, relates to a kind of flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling device specifically, belongs to the highway maintenance equipment technical field.
Background technology
Asphalt surface hot reproduction routine servicing and in-situ heat regeneration construction technology are used more and more widely at present, one of key technology of these technologies is exactly the heating technique of flexible pavement, China's utility model patent (patent No. 97236446.3, patent name: flexible pavement heat energy regeneration repairing heater) disclose a kind of asphalt surface hot wall (plate), not having the road pavement temperature to carry out overall process when the heating flexible pavement detects in real time, just the road pavement temperature detects after the heating total time of setting finishes, can cause pavement temperature too high or too low like this, the too high ground surface material that causes is burnt, can not regeneration, cross to hang down and then can not soften, need reheat, the efficiency of heating surface is low, has a strong impact on the quality and the efficient of asphalt surface hot reproduction routine servicing and in-situ heat regeneration construction.
The utility model content
Technical problem to be solved in the utility model just is to overcome the defective that prior art exists, and a kind of flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling device is provided, and can detect in real time heating-up temperature.
The utility model flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling device is made up of infrared temperature detector (claiming infrared temperature sensor again), analog module, heater automatic controller, man-machine interface, electromagnetic valve; The heater automatic controller includes programmable cpu module and a plurality of relay, and the set combustion gas unrounded number of the number of the relay that infrared temperature detector number and heater automatic controller have and flexible pavement heating pad wall is identical; Each infrared temperature detector is installed on respectively in the heat radiation zone of each combustion gas mouth combustion zone, each infrared temperature detector is transferred to the heater automatic controller with the pavement temperature information that collects through analog module, and the temperature information that the programmable cpu module transmits according to each the infrared temperature detector that obtains passes through the open and close of corresponding relays control electromagnetic valve; Man-machine interface is used for realizing human-computer dialogue with programmable cpu, sets controlling parameter.
The utility model flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling device, can detect in real time heating-up temperature, and the heating-up temperature in control heat radiation zone remains in the predefined temperature range, flexible pavement effectively heated, and can prevent that flexible pavement is by burned.
Description of drawings
Fig. 1 is the utility model flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling apparatus structure and control circuit schematic diagram;
Fig. 2 the utility model flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling apparatus control program block diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: as shown in Figure 1, flexible pavement heating pad wall heating-up temperature Detection ﹠ Controling device is made up of infrared temperature detector 4 (claiming infrared temperature sensor again), analog module (EM235) 3, heater automatic controller (PLC) 2 (for the existing product that is purchased), man-machine interface 1, electromagnetic valve 5; The heater automatic controller includes programmable cpu module and a plurality of relay 7, and the set combustion gas unrounded number of the number of the relay that infrared temperature detector number and heater automatic controller have and flexible pavement heating pad wall is identical; Each infrared temperature detector is installed on respectively in the heat radiation zone of each combustion gas mouth combustion zone (described heat radiation zone is between heating pad wall and flexible pavement 6), each infrared temperature detector is transferred to heater automatic controller 2 with the pavement temperature information that collects through analog module, and the temperature information that the programmable cpu module transmits according to each the infrared temperature detector that obtains passes through the open and close of corresponding relays 7 control electromagnetic valve.
Its course of work is as follows: at first by infrared temperature detector 4 temperature value of detected thermal radiation field is transferred to the heater automatic controller.When work, at first on man-machine interface 1, configure the total time of heating, the upper limit and the lower limit of heating-up temperature, press the some ever-burning flame touch button on the man-machine interface, PLC output relay coil gets, get the constant open contact closure mutually continuously with the heating pad wall high-tension coil, high-tension coil gets electric and discharge over the ground, the some ever-burning flame.Whether ever-burning flame is lighted, and need manually observe.Above step is the action of prior art.After ever-burning flame is lighted, press the startup heat button, PLC begins countdown.At this moment to the relay coil energising, with the constant open contact closure that the electromagnetic coil of electromagnetic valve 5 links to each other, electromagnetic valve 5 is opened, and corresponding zone begins heating.After starting heating,, be cooled to lowest temperature then, and then start heating, so between the temperature bound, circulate, use until exhausted up to total time along with the temperature of carrying out that heats rises to the temperature upper limit setting value always.Infrared temperature-test sensor 4 links to each other with EM235, and infrared temperature-test sensor is passed the standard electric signal of 4-20mA back during work, becomes corresponding temperature value by the A/D module converts in the EM235, and programmable cpu compares this temperature value and setting value.Measured value is less than the lower limit of setting value, and the output relay 7 of PLC gets electric, and with the constant open contact closure that the electromagnetic coil of electromagnetic valve 5 links to each other, electromagnetic valve is opened, and corresponding zone begins heating; Measured value is greater than the higher limit of setting value, output relay 7 dead electricity of PLC, and the constant open contact that links to each other with the electromagnetic coil of electromagnetic valve 5 disconnects, and electromagnetic valve 5 cuts out, and corresponding zone begins to stop to heat.
