The key points of the technical scheme are that the system comprises a monitoring device, a single chip microcomputer, a temperature detecting device and a cooling device, wherein the monitoring device, the temperature detecting device and the cooling device are all connected with the single chip microcomputer. The temperature measuring system for the large-volume concrete has the beneficial effects of accurately monitoring the internal temperature of the concrete, automatically adopting a cooling measure, improving the quality and being applicable to large-volume concrete temperature measurement.
Description
Technical field
The utility model relates to the concrete measuring temperature technology, relates in particular to the concrete in mass temp measuring system.
Background technology
Build in the process at large-sized concrete, concrete multiple spot is monitored in real time, important effect is arranged ensureing concrete pouring quality.Its reason is: cement has produced a large amount of heats in hydration process, when inside concrete and surface temperature difference are excessive, will produce thermal stresses, during restraint forces inside and outside thermal stresses surpasses concrete, will produce the crack.Therefore, prevent that key that the crack appears in concrete from being the control inside concrete and the temperature difference on surface.At present, in many enterprise constructions the thermometric of concrete in mass is taked following measure: before the casting of concrete in mass, reserve thermometric hole or pre-buried temperature tube at privileged site, use equipment such as glass bulb thermometer, electronic instrument for measuring temperature, press certain time interval by the special messenger, the degree of depth different in reserving hole or pre-buried temperature tube are carried out thermometric and record, through further artificial data processing, make counter-measure again.This method has spent great amount of manpower, energy, and the accuracy of data and promptness can not get guaranteeing.Do not have temperature data accurately, can not accurately control, will the quality of large-sized concrete be exerted an influence, produce the crack, cause quality accident the temperature of large-sized concrete.
The utility model content
Technical problem to be solved in the utility model is: at conventional art thermometric labor intensive and the inaccurate deficiency of data that obtains, propose a kind of concrete in mass temp measuring system of full-automation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the concrete in mass temp measuring system, comprise monitoring device, single-chip microcomputer, temperature-detecting device and cooling unit, described monitoring device, temperature-detecting device and cooling unit all connect single-chip microcomputer.
Described monitoring device adopts computer, and with single-chip microcomputer between adopt the RS-485 bus to be connected.
Described single-chip microcomputer is the STC89C51RC single-chip microcomputer.
Described temperature-detecting device comprises N digital temperature sensor, 1≤N≤16, and be integer.
The beneficial effects of the utility model are: accurately the monitored concrete internal temperature, take cooling measure automatically, improve the quality.
Description of drawings
Fig. 1 is the utility model construction system block diagram.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model proposes a kind of concrete in mass temp measuring system of full-automation at conventional art thermometric labor intensive and the inaccurate deficiency of data that obtains.As shown in Figure 1, this system comprises monitoring device, single-chip microcomputer, temperature-detecting device and cooling unit, and described monitoring device, temperature-detecting device and cooling unit all connect single-chip microcomputer.
Embodiment:
Concrete in mass temp measuring system in this example comprises computer, single-chip microcomputer, temperature-detecting device and cooling unit, and described monitoring device, temperature-detecting device and cooling unit all connect single-chip microcomputer.Single-chip microcomputer can adopt the compatible STC89C51RC single-chip microcomputer of IntelMCS-51 series, temperature-detecting device can adopt a plurality of DS18B20 digital temperature sensors to form, the ability that articulates according to single-chip microcomputer generally is no more than 16, adopt the RS-485 bus to be connected between computer and the single-chip microcomputer, form the RS-485 network, because the RS-485 wiring is simple, only need to use two lines just can form whole network, add RS-485 in theory maximum transmission distance can reach 1.2 kilometers, can reach 9.6 kilometers in theory if add repeater (maximum 8), be particularly suitable for the large-scale industry measurement and control area.
Its specific implementation process is as follows: 1. before the concreting, press the technical specification good temperature pick up of mounting arrangements at the scene, and to every temperature pick up numbering (user's definition).The every 100m of general requirements
23 sampled points of pouring layer cloth, sampled point is arranged and is quincunx.(every thermometric single-chip microcomputer of native system can articulate 16 temperature transducers, so at 500m
2Only need to install a thermometric single-chip microcomputer in the pouring layer scope.Can save RS-485 network layout labour intensity); 2. install cooling unit by technical specification; 3. after the concreting, the user sets concrete internal temperature warning bound according to the sampled point difference of measuring concrete surface and internal temperature sensor.Native system provides single-point acquiring, single line collection, single station collection, the whole network collection, five kinds of modes of timing acquiring, and timing acquiring user's blanking time can be provided with voluntarily.4. after concrete internal temperature surpassed alarm limit, native system can send alarm signal, simultaneously by the start and stop of Single-chip Controlling cooling unit, realized the automatic function of concrete cooling.5. after concrete curing finished, the outer lead that only needs to cut off temperature pick up at concrete surface got final product.The temperature pick up that adopts in the native system is a medical disposable material, and is tiny relatively, is embedded in inside concrete, can not influence concrete pouring quality.The temperature that single-chip microcomputer collects temperature pick up in the native system passes to computer in real time and monitors, and shows with the temperature curve form in real time, also can generate form and printing, and is very directly perceived.
The utility model scope required for protection is not limited in the foregoing description; those skilled in the art is easy to according to foregoing description the technical solution of the utility model be changed the technique effect that reaches same slightly, and it all belongs to protection domain of the present utility model.
