Description
Food Temperature Monitoring System
This invention relates to a food temperature monitoring system.
There are many circumstances in which the temperature of food needs to be monitored, particularly in storage where departure from a particular temperature may result in over rapid ripening (for example in the case of fruit) or in the case of frozen food wherein over heating can cause quality loss and possible food poisoning. Similarly when food is to be kept hot, as in an eating establishment, it is essential that the temperature does not fall low enough for micro-organisms to live in or on the food and therefore possibly causing poisoning.
It is further desirable if the temperature of all such products should be periodically monitored and also recorded so that in the event of for example an outbreak of food poisoning it is relatively simple to check the records and determine whether or not temperature variation had been the contributory cause.
It is an object of the present invention to provide a food temperature monitoring system which allows the above desiderate to be achieved.
The invention provides a food temperature monitoring system including a control unit and a plurality of remote wireless sensor units, each sensor unit including a temperature sensor, a power source, a processor and an aerial and the control unit including a central processing unit, an aerial and an alarm, the control unit and the sensor units being capable of mutual two-way communication.
The invention also provides a food temperature monitoring system including a control unit and at least one remote wireless sensor unit, each sensor unit including a temperature sensor, a power source, and an aerial and the control unit including a central processing unit, an aerial, the at least one remote sensor unit being capable of transmitting temperature information to the control unit.
The invention also provides a method of monitoring the temperature of a plurality of food units including providing a system as aforesaid, moving said remote sensor units sequentially to the various food units and disposing the temperature sensor in a position to sense the temperature of the unit, operating the remote sensor to transmit said temperature to the control unit.
There can be one or a plurality of remote sensor units.
The or each sensor unit can have a probe for entering into the food unit.
Desirably the control unit is adapted sequentially to monitor all the remote sensor units, each of which has an individual digital address.
Desirably each sensor unit is adapted, when not so addressed to enter a quiescent power state to reduce drain on its power source and periodically to leave that state to ascertain whether or not it is being addressed.
Desirably each remote sensor unit is individually capable upon detecting exceeding of a temperature threshold individually to send a signal to be received by the control unit to indicate a potential alarm condition.
The control unit can be adapted, upon receipt of such a potential alarm signal from a remote sensor to monitor the temperature at that sensor intensively for a short period of time before determining whether a false alarm or a true unwanted temperature deviation has arisen.
Desirably the control unit is adapted, upon detection of an unwanted temperature deviation to emit an audible and/or visual indication to adjacent personnel. Optionally and/or additionally, the central control unit can include a modem capable of being actuated to transmit such information to a remote location, eg a manned operating headquarters to indicate that immediate action is desirable.
Desirably the central control unit is adapted to store the results of its periodic monitoring in a memory system. Such memory can again be connectable to the modem and dump its contents at pre-determined or other control intervals to a remote processing location where a permanent store can be made or whereby permanent monitoring can be achieved.
Desirably each remote sensor unit has its threshold or thresholds capable of being adjusted. The or each threshold can be set at the remote unit, but desirably is set from the central control unit by means of an activating signal affecting software within the sensor unit.
The control unit can have an alphanumeric display or other means of indicating which particular sensor unit has initiated an alarm for the inputting of thresholds and comparable information a keyboard can be provided.
Desirably each sensor unit has a tamper-indicating device to indicate if it is moved within a desired area or if it is interfered with. For example, a sensor desired to be placed in a particular position within a freezer can be associated with a magnetic plate on a freezer wall or the like. Upon movement of the sensor unit the change in the magnetic field can be sensed by a device within the sensor unit which can then emit a signal to the control unit indicating that tampering or dislodgement has taken place.
The invention will be described further by way of example, with reference to the accompanying drawings wherein;
Figure 1 is a schematic plan view illustrating a preferred system of the invention;
Figure 2 shows a control unit of the system; and
Figure 3 shows a unit of the system.
The temperature monitoring system (10) of the invention is particularly suitable for use in connection with a store (11) which might keep and sell frozen food in a plurality of freezers (12). It will be appreciated that if one of the freezers (12) should break down, or if its door should be left open it is possible for the contents to rise above a desired freezer temperature, for example -15 C. If this happens there is a possibility of deterioration of the food which might lose its quality or perhaps become capable of causing food poisoning.
Whilst most fridges will have a visual indication of their temperature, it is not always possible for monitoring staff to take the time and effort to check each refrigerator at regular intervals. This is particularly true during the night when the store may be closed and no staff present.
The system (10) of the invention includes a central control unit (13) which will usually be mains powered but can have a battery powered back-up and a plurality of remote sensor units (14) disposed one in each refrigerator (12).
The control unit (13) (figure 2) may be mounted on a wall (15) and may have a power connection (16), a central processing unit or micro-chip computer,a receiving and transmitting aerial (18), audio and/or visual alarm means (19) (20), an alpha-numeric display (21) and a keyboard (22) all connected to the CPU (17).
The central control unit may also have appropriate indicator lights to show that it is functioning or various other of its operational requirements. Incorporated in or separate from the
CPU can be a memory (23) whose contents can be removed either by a plug connection indicated at (24), or via a modem (25) connected to a telephone line (26). The contents of the removable memory can be stored for example, in a floppy disk or can be produced as hard copy in the form of a printer.
Each remote sensor unit (14) can be adapted to be secured to a wall (27) of a fre r by means of a magnetic connection (28).
A tamper sensor (29) can be associated with the magnetic connection (28). The sensor unit (14) has a casing in which are a microprocessor (30), a power source (31) such as a battery, a temperature sensor (32) and a receiving and transmitting ariel (33).
In a further arrangement, not illustrated, each remote sensor unit (14) can be attached in position by means of VELCRO (registered trade mark) strips and the tamper sensor (29) instead of being a reed switch can be a tilt switch.
A unique address is associated with the unit (14) and in any one system (10) the control unit (13) will periodically address all the remote units (14). Upon being actuated by detecting receipt of its own address each sensor unit (14) will transmit its temperature reading to the control unit (13) which will note and record this in its memory (23). This will take a relatively short proportion of the life of the sensor unit (14), and, therefore, in order to reduce drain on the power source (31) the sensor unit will be adapted to enter a quescent power mode in which power consumption is very low. The unit (14) will leave that stage at intervals in order to sense whether or not it is being addressed.The microprocessor (30) will also be programmed to react, upon the detecting of a temperature threshold (previously set in its memory) to activate the aerial (33) to transmit an alarm signal to the control unit (13). The control unit (13), apart from recording and logging the occurrence may then give a warning for personnel to attend the unit in question (identifiable by its own address transmitted as part of the signal) or may carry out further monitoring of the remote sensor unit (14) for a brief period of time to ascertain whether or not the temperature sensor (32) is, in fact, giving a high temperature reading of the threshold or there is some kind of fault.
Once a fault condition is indicated the central unit can give an audio or visual warning to adjacent staff that action needs to be taken. The central control unit can also be programmed, so that it is made aware as to when the store (11) is manned or when it is unmanned, for example at night. In the latter case the control unit (13) can be adapted to transmit its warning signal via the wiring connected to (24), or via the modem (25) to a remote location, for example a company regional or national headquarters which can be alerted to attend the store or alert staff upon arrival the next day.
It will be appreciated that the threshold temperature at which the various sensor units (14) operate may vary depending on the type of food being stored and the nature of the processor (30) either directly in the sensor, or, more conveniently by radio signal from the control unit (13), the various thresholds being introduced using the display (21) and the keyboard (22).
Similarly, the display (21) can be used to indicate which of any of the remote sensor units is indicating a high temperature condition.
It will be appreciated that the system of the invention is particularly useful and convenient in that not only can the temperatures of all the various food containers or storage areas be monitored continuously, and their temperatures recorded and transmitted to a remote location, but in the event that any threshold is broken, each remote sensor is individually programmed to give an immediate alert to the central unit. This gives a particularly rapid response to breach of temperature threshold.
The invention is not limited to the precise details of the foregoing and variations can be made thereto. For example, connection between the remote sensor units and the central control unit by ultrasound or radiation other than radis waves would be possible.
The invention is not limited to the monitoring of temperature in freezer establishments, but is also usable in establishments where food has to be kept hot. A similar system can operate within a food storage compartment such as an oven or heated cabinet. It will also be appreciated that as the remote sensor units are individually programmable the temperature in the individual sensor unit does not have to be the same and the temperature in the various different sorts of cabinets, for example freezer cabinets at a very low temperature and chilled cabinets for salads and like materials can also be maintained.
The invention also has application in the industrial storage of products such as fruit which need to be kept at a carefully controlled temperature to prevent premature ripening.
In a further possibility (not illustrated) instead of there being a plurality of remote sensor units each disposed in an individual food storage unit such as a refrigerator, a single or a small number of remote sensor units can be provided and can be manually or otherwise transported at regular intervals around the various food storage units to be monitored. The or each remote sensor units can comprise a probe and an activating switch. An operative can carry the remote sensor unit to a particular food storage unit, insert the probe into such unit and after a predetermined time has elapsed to allow normalisation of the temperature sensed by the probe can operate a switch to cause the circuitry within the remote sensor unit to transmit temperature and other information (if desired) to the control unit which can record and process it as previously described.
One or more remote sensor units can be located in a refrigerated transport vehicle so that the temperature of contents can be monitored from the pick-up point to the delivery point.
Information relating to the temperature of the refrigerated contents during transit can be recorded in any appropriate way and stored for extraction by any suitable means upon arrival at the destination. The information in the memory can be down loaded on arrival which can also alert the receiver that the delivery has arrived. If during transit the temperature of the refrigerated volume rises above the threshold level the driver of the vehicle can be warned by any appropriate warning signal whether the driver is in the vehicle or not.
Many other variations are possible within the scope of the invention.
