Description

The chemical reactor long distance control system
Technical field
The utility model has related to a kind of chemical reactor long distance control system, belongs to the chemical reactor technical field.
Background technology
We know that being permitted eurypalynous chemical reaction is that requirement is carried out under the constant temperature again, if do not satisfy certain temperature conditions, chemical reaction can not normally carry out, can't obtain due reaction result, therefore temperature of charge is very important parameter in the chemical reaction, must accurately control, although existing chemical reactor can carry out comparatively accurate temperature control, but need operating personnel to operate at the scene, owing to easily producing some harmful materials in the chemical reaction process, thereby caused larger impact in operating personnel healthy.
The utility model content
Technical problem to be solved in the utility model provides a kind of chemical reactor long distance control system, can be by the temperature in the long-range computer control chemistry reactor, and the reaction scene need not staff's operation, has ensured staff's security.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of chemical reactor long distance control system comprises the microprocessor control module, and described microprocessor control module is connected with bidirectional triode thyristor and temperature sensor, and described bidirectional triode thyristor is connected with 220V AC power, chemical reactor; Described temperature sensor is connected with chemical reactor, and described microprocessor control module is connected with host computer by the RS485 communication module.
Aforesaid chemical reactor long distance control system is characterized in that: described bidirectional triode thyristor is connected with the microprocessor control module by the zero cross fired chip.
Aforesaid chemical reactor long distance control system is characterized in that: also be connected with zero cross detection circuit on the described microprocessor control module, described zero cross detection circuit is connected with the 220V AC power.
Aforesaid chemical reactor long distance control system is characterized in that: also be connected with the short message notification module on the described microprocessor control module.
Aforesaid chemical reactor long distance control system is characterized in that: also be connected with alarm module on the described microprocessor control module.
The beneficial effects of the utility model are: by the temperature in the temperature sensor collection reactor, uploading to host computer after the microprocessor control module is processed shows, stores, and the temperature that the temperature that gathers is set in host computer compares, poor according between the two, the temperature that adds by bidirectional triode thyristor control reactor, until the temperature that the temperature that gathers equals to set makes the reactor stopped heating, realized the remote monitoring to reactor temperature.
Description of drawings
Fig. 1 is the module connection diagram of the utility model chemical reactor long distance control system.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of chemical reactor long distance control system comprises the microprocessor control module, and described microprocessor control module is connected with bidirectional triode thyristor and temperature sensor, and described bidirectional triode thyristor is connected with 220V AC power, chemical reactor; Described temperature sensor is connected with chemical reactor, described microprocessor control module is connected with host computer by the RS485 communication module, described bidirectional triode thyristor is connected with the microprocessor control module by the zero cross fired chip, by the temperature in the temperature sensor collection reactor, uploading to host computer after the microprocessor control module is processed shows, storage, and the temperature that temperature and the host computer of collection are set compares, the pid control algorithm of microprocessor internal carries out computing to both deviations and obtains an output controlled quentity controlled variable, the temperature that adds by zero cross fired chip and bidirectional triode thyristor control reactor, until the temperature that the temperature that gathers equals to set makes reactor not in heating.
Also be connected with zero cross detection circuit on the described microprocessor control module, described zero cross detection circuit is connected with the 220V AC power, detect the zero crossing moment of the 220V alternating current of 50HZ, and constantly export the zero-crossing pulse with certain width at zero crossing, remind the microprocessor zero crossing constantly to arrive, for whole control device provides time reference.
Also be connected with the short message notification module on the described microprocessor control module, the temperature that collects can be sent on the good mobile phone of prior binding by short message, so that operating personnel's reference.
Also be connected with alarm module on the described microprocessor control module, when the temperature in the reactor surpasses the scope of setting, report to the police by alarm module, the prompting staff carries out overhaul of the equipments.
In sum, a kind of chemical reactor long distance control system that the utility model provides can be by the temperature in the long-range computer control chemistry reactor, and the reaction scene need not staff's operation, has ensured staff's security.
Above demonstration and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
