In the report generation function, templates such as a report and an application form are stored in the storage unit 63 of the processing server 6, and a report or the like is automatically generated based on input measurement data. An example of a report is a regular noise report at a construction site.
The statistical processing function calculates the average value based on the measurement data, calculates the first derivative value, the second derivative value, etc. of the generated graph, and makes mathematical judgments such as the correlation coefficient from the shape of the graph An index is calculated.

  In a system different from the moving image processing function, processing for compressing a video signal photographed by the camera of the monitor device 8, effect processing for generating extracted data border, tracking frame, etc., and synthesizing the extracted image with other images There are a composition process, a telop process for discriminating a characteristic part of an image, and inserting a corresponding message.

The composition process includes, for example, composition that superimposes store layout images and customer flow lines.
In the telop process, a message corresponding to the characteristic pattern of the image is registered as a correspondence table in the storage unit 63, and the control unit 61 determines whether or not the input image matches the registered characteristic pattern. In this case, the corresponding message is inserted as a telop.

  The voice processing function converts a voice message corresponding to measurement data or monitor data into voice and outputs the voice. For example, when it is determined from the measurement data that the equipment device 1 is abnormal, the abnormality of the equipment device 1 is output by voice.

The automatic recognition determination function is divided into a function related to images and a function related to sound.
Functions related to voice include a voice recognition function for recognizing input voice and outputting a specific message, and a prediction function for predicting failure of the equipment device 1 from abnormal sounds. For voice and abnormal sounds, the corresponding sound pattern is registered in the storage unit 63 in advance, and the control unit 61 compares the input sound with the registered sound pattern and falls within a numerically allowable range designated in advance. Thus, when it is determined that they match, a message or prediction is output.

Functions related to images include a risk level, an urgency ranking function, a theft / disaster monitoring function, an employee service / attire monitoring function, a work attitude monitoring function, and a customer information monitoring function.
The risk level and urgency ranking function means that the control unit 61 recognizes an image pattern for a moving image or a still image, compares it with the risk pattern and emergency pattern registered in advance in the storage unit 63, and registers the registered risk pattern and emergency pattern. If it matches, the risk level and the urgency level are ranked and output.

  The theft / disaster monitoring function is that the image pattern of theft / disaster is registered in the storage unit 63 in advance, and the control unit 63 displays or outputs the theft / disaster as a theft / disaster when the input image matches the image pattern. Output.

  The employee service / attire monitoring function calculates the average distance between the customer and the employee from the input image, and the customer service is not good when the average value exceeds a predetermined reference value. And display output or audio output.

  In addition, when the employee's shape pattern is recognized from the input image and the shape pattern is significantly different from the shape pattern registered in the storage unit in advance (when the similarity between the two shape patterns is small), the employee's clothes Display output or sound output to the effect that is not appropriate.

  The work attitude monitoring function recognizes an employee's shape pattern from an input image, and enables monitoring of employee's leaving the department, private mobile use, excess breaks, and the like.

  The customer information monitoring function is to monitor movement from an input image based on a flow line of a visitor (customer) in the store. As the movement, the normal flow line and the abnormal flow line are displayed and output so as to be distinguishable, and the customer's gender and approximate customer age are also displayed and output.

  For the sex and age of the customer, a standard shape pattern is registered in advance in the storage unit 63 for each gender and age, and when recognizing the customer's shape as a pattern, a comparison with the standard pattern is performed. According to the standard pattern that most closely approximates, it is designed to identify which gender and which age.

Next, the determination made based on the acquired data in the processing server 6 will be described. The following example is a case where a graph waveform of an electric signal based on a time change such as sound, light, vibration, etc. is used.
Compare the shape of the graph edited based on the acquired data, or the graph after superposition, and the shape of the graph when it is determined that the abnormality is registered in the storage unit of the processing server 6 in advance. Based on the degree, it is determined whether or not the current graph waveform shows any abnormality.

  Furthermore, in the above example, in order to determine the coincidence, the characteristic value of the graph, such as the peak height (vertical axis), the peak position (horizontal axis) value, or the numerical value of the area surrounded by the peak Compare with the same characteristic value of past data.

  Specifically, it applies to the discovery of abnormalities caused by loose bolts and nuts in elevators, automobiles, motorcycles, railways, park playground equipment, etc. equipped with rotating machines such as motors and engines.

It applies to the discovery of abnormalities such as aging and construction defects of invisible parts such as interior walls, floors, and ceilings of buildings, as well as abnormalities in plant health due to the sound of trees.
Furthermore, it can be applied to general quality control by sound such as decay of the contents of canned foods or less than specified capacity.

Next, an example of the flow line display of visitors will be described with reference to FIG. FIG. 11 is a diagram illustrating a flow line display example.
As shown in FIG. 11, the inside of the store is photographed with the camera of the monitor device 8 to recognize the moving visitor and store the walking trajectory. Since a technique for recognizing a moving object and grasping its trajectory has already been provided, this technique is used.

  Then, the map point in the store is given to the trajectory from the shooting site map (map showing the inside of the store) and the shooting range, and the map in the store displayed on the x-axis and y-axis corresponds to the coordinate point In addition, the trajectory is drawn as a flow line. Furthermore, in the map in the store, product information such as a product number is set on the coordinate point corresponding to the actual store.

In FIG. 11, the product numbers (1) to (7) are sequentially viewed as normal flow lines, whereas the product numbers (8), (5), (6), A view of the product is drawn in the order of (9). Thus, displaying the flow line together with the product information on the map in the store has an effect of easily grasping the customer's trend.
Further, in this display example, if information by gender and age is drawn in a flow line with different colors, it is possible to easily analyze customer trends.
