Description
Technical field
The present invention relates to a kind of chemical reactor long distance control system, belonged to the chemical reactor technical field.
Background technology
We know that the chemical reaction of many types is that requirement is carried out under the constant temperature again; If do not satisfy certain temperature condition, chemical reaction can not normally carry out, and can't obtain due reaction result; Therefore temperature of charge is very important parameter in the chemical reaction; Must accurately control,, need operating personnel to operate at the scene though existing chemical reactor can carry out comparatively precise dose control; Owing to be easy to generate some harmful materials in the chemical reaction process, thereby caused bigger influence in health of operators.
Summary of the invention
Technical matters to be solved by this invention provides a kind of chemical reactor long distance control system, can be through 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 present invention adopted is:
A kind of chemical reactor long distance control system comprises the microprocessor control module, and said microprocessor control module is connected with bidirectional triode thyristor and temperature sensor, and said bidirectional triode thyristor is connected with 220V AC power, chemical reactor; Said temperature sensor is connected with chemical reactor, and said microprocessor control module is connected with host computer through the RS485 communication module.
Aforesaid chemical reactor long distance control system is characterized in that: said bidirectional triode thyristor is connected with the microprocessor control module through 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 said microprocessor control module, said 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 said microprocessor control module.
Aforesaid chemical reactor long distance control system is characterized in that: also be connected with alarm module on the said microprocessor control module.
The invention has the beneficial effects as follows: gather the temperature in the reactor through temperature sensor; Upload to after the microprocessor control module is handled that host computer shows, storage, and the temperature that the temperature of gathering is set in host computer compares, poor according between the two; The temperature that adds through the bidirectional triode thyristor controlling reactor; Until the temperature that the temperature of gathering equals to set, make reactor stop heating, realized remote monitoring to reactor temperature.
Description of drawings
Fig. 1 is that the module of chemical reactor long distance control system of the present invention connects synoptic diagram.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1, a kind of chemical reactor long distance control system comprises the microprocessor control module, and said microprocessor control module is connected with bidirectional triode thyristor and temperature sensor, and said bidirectional triode thyristor is connected with 220V AC power, chemical reactor; Said temperature sensor is connected with chemical reactor; Said microprocessor control module is connected with host computer through the RS485 communication module; Said bidirectional triode thyristor is connected with the microprocessor control module through the zero cross fired chip; Gather the temperature in the reactor through temperature sensor, after the microprocessor control module is handled, upload to host computer and show, store, and the temperature that the 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; Through the temperature that adds of zero cross fired chip and bidirectional triode thyristor controlling reactor,, make reactor not in heating until the temperature that the temperature of gathering equals to set.
Also be connected with zero cross detection circuit on the said microprocessor control module; Said zero cross detection circuit is connected with the 220V AC power; Detect the zero crossing moment of the 220V alternating current of 50HZ; And export zero-crossing pulse constantly with certain width at zero crossing, remind the microprocessor zero crossing constantly to arrive, for the The whole control device provides time reference.
Also be connected with the short message notification module on the said microprocessor control module, can the temperature that collect be sent on the good mobile phone of prior binding through short message, so that operating personnel's reference.
Also be connected with alarm module on the said microprocessor control module, when the temperature in the reactor surpasses the scope of setting, report to the police through alarm module, the prompting staff carries out overhaul of the equipments.
In sum, a kind of chemical reactor long distance control system provided by the invention can be through the temperature in the long-range computer control chemistry reactor, and the reaction scene need not staff's operation, has ensured staff's security.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
