Description

Food Hazard Critical Point Management System

The present invention relates to a food hazard factor management system applicable to the facilities of a food manufacturing company or a facility of a group meal place, and in particular, for the management of hazards of food, various facilities, schools, Food hazard element central management system that records a series of data on temperature, humidity, and time in the entire process from food receipt, storage, shipping, and cooking to group meal facilities such as companies, hospitals, hotels, and so on. It is about.

As is well known, this system identifies the causes of food contamination and alteration so that NASA can improve the safety of food by focusing on food manufacturing and cooking process. We have newly established the provisions of Paragraph 2 (Hazard Factors Critical Control Standards) and operate it in the form of an autonomous certification system that approves and approves candidate companies. Currently, 22 food companies are designated as applied companies. According to these Hazard Control Standards, food safety is improved and food safety is maintained. In addition, it is possible to manufacture safe foods, which can reduce the damages caused by the occurrence of defective products or accidents or the cost loss due to the collection of defective products, reduce the number of microbial inspections on the final products, and recognize them as safe foods for domestic and foreign users. The advantage is that it can create more demand.

On the other hand, it is essential to monitor the CRCP (CRITICAL CONTROL POINT) in order to meet these Hazard Critical Control Points, and for this purpose, it is difficult to record the temperature, hygrometer indication and cooking time of each facility. Therefore, the automatic recording instrument is used to record, but when such indication value is out of the normal range, there is no effective way to immediately alert and take measures. In particular, the existing facilities can detect and record such temperature and humidity. And there is a problem that a huge burden of facility costs is inevitable in order to provide a proper alarm and measures when an abnormality occurs.

The purpose of the present invention is to use the facilities of a food company or a group lunch place as it is to solve these problems, the risk factors such as temperature, humidity measurement and alarm, measures in the entire process of the receipt, delivery, cooking of food with a minimum installation cost It is to provide a food hazard management system that provides a set of functions that meet the management criteria.

The purpose of the present invention is to utilize the facilities of the existing food company or the facilities of the group meal place as it is, to attach the temperature and humidity sensors to them, and to store these temperature and humidity sensors in the terminal itself, and also through a modem Sequential transmission to the central computer installed in the place, and the central computer to store these sequentially transmitted temperature and humidity values and compare with the reference value to propose a food hazard management system that is equipped with a program for immediate action in the event of an abnormality do.

Accordingly, the present invention can minimize the cost required for the management of food hazards, and when an abnormality occurs, there is an effect that enables more efficient measures as well as an alarm.

Referring to the present invention in more detail with reference to the accompanying drawings as follows.

An example of a terminal for practicing the present invention is shown in FIG.

As can be seen from the above, the present invention comprises a system clock (1), a ROM (2), a RAM (3), a memory (4) consisting of a hard disk, and the like, and a CPU (5) and a watchdog timer (6). In the known terminal 7, a temperature sensor 8 and a humidity sensor 9 installed in various facilities such as a refrigerator compartment, a freezer compartment, a refrigerator, a freezer, a fryer, an oven, and a heater and a freezer, In a known configuration comprising a controller for selectively controlling a compressor (not shown in the figure) for a cooler, for converting the signals of the temperature sensor 8 and the humidity sensor 9 from analog to digital signals. A plurality of terminals 7 comprising an A / D converter 10 and a modem 11 for transmitting these converted digital signals,

Central computer 12 for transferring data to modems 11 composed of ROM 2 'and RAM 3' and a hard disk or array and CPU 5 'and connected to a plurality of terminals 7; )Wow,

A dialing circuit 13 connected to the central computer 12 to enable automatic reporting to an external institution telephone, and a voice synthesis circuit 14 for storing and reproducing voices;

Alarm means 15 is connected to the input and output ports of the terminal 7 is controlled by the operation of the speaker and warning lights, and the external organ computer 16 connected to the central computer 12.

In the present invention as described above, after the power is applied to each part, the terminal 7 and the central computer 12 are started by their own program.

That is, as described above, the terminal 7 uses the temperature sensor 8 and the humidity sensor 9 installed in various equipments such as a refrigerator compartment, a freezer compartment, a refrigerator, a freezer, a fryer, and an oven to present the temperature and humidity values of the current facilities. The signals output from these sensors are converted from analog to digital signals by the A / D converter 10, and the converted values are immediately stored in the memory 4 such as a hard disk built into the terminal 7. It is included in. In addition, since the temperature and humidity of each process in the cooking, freezing, and refrigerating facilities of the food maintain a preset range in this way, the central computer 12 uses a plurality of kitchens in a plurality of kitchens to connect the terminal 7 to the terminal 7. The data transmitted is stored periodically for each facility. In this process, if any equipment in a kitchen is out of the set temperature and humidity range, the initial process waits for a certain time so that normal control can be achieved by the operation of its own control circuit installed in the corresponding refrigeration and refrigeration equipment. In this process, if the temperature and humidity of each equipment returns to the normal range, the temperature and humidity should be recorded periodically. If the temperature and humidity are out of the normal range, the controller installed in each equipment uses the heater, compressor or compressor compressor. Selectively control to return to the normal state.

In addition, the digital values of temperature and humidity measured by this process are transmitted to the central computer 12, and these digital values are all stored and accumulated in a hard disk or an array. A database constructed of temperature data and humidity data is managed by the central computer 12.

In addition, when the temperature and humidity deviation deviates from the range normally controlled by the controller for more than a predetermined time in a series of processes such as normal refrigeration, refrigeration, or heating for food cooking, the controller is regarded as having an abnormality and the central computer ( 12) is to operate the alarm buzzer through the modem 11 to generate an alarm sound, so that the warning light is emitted to the surrounding workers to detect the abnormality and take appropriate measures.

Even in this state, if the temperature and humidity range of each facility does not return to normal, the central computer 12 transmits the corresponding data to the after-service specialized company computer, which is an external agency computer 16 connected by a dedicated line, or operates the voice synthesis circuit 14. By making the incident accepted by telephone, the trouble shooting team will be dispatched to take appropriate measures. At this time, the data reporting the abnormality to the after-sales service center connected by a dedicated line may be a business ID, a business address, a business telephone number, an abnormal facility ID, a current temperature, a current humidity, an error occurrence time, a current time, and a parity bit.

In addition, in the case of synthesizing the voice in the voice synthesis circuit 14, the voice can be synthesized in the same order as that of the above-described data type. Also, when the line becomes available after the operation of the dialing circuit, the voice signal is sequentially synthesized. It will be able to complete the voice signal by sending it to the relevant authority.

In addition, the external institution computer 16 may be an after-sales center, emergency parts, article supply center, as described above, it can be selected according to the characteristics of each occupation.

In this way, the present invention can completely automate a series of temperature and humidity recording processes unlike the conventional case in which an operator periodically records the recorded temperature and humidity using a separate automatic temperature and humidity recorder. While the output value by the sensor is collected, recorded and managed by the central computer 12 through the terminal 7 and the dedicated line, it immediately alerts in case of an abnormality and automatically reports to the relevant institutions as necessary to focus on managing various food hazards. Of course, if an abnormality occurs, it is possible to quickly take action.

Accordingly, it is possible to promote the safety of dietary life by the risk factor management function by the central computer 12 without burdening the facility cost for each business, and it is not only economical because it requires no huge facility investment for the risk factor management. There is a useful effect such as to prevent the occurrence in advance.
