EXAMPLE

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of an automatic counting apparatus according to the present invention. In the drawing, reference numeral 10 denotes a host computer, which may be a conventional 386 or higher computer, and the host computer 10 may include a controller ( 20) can be installed by adding up to 256 units. The host computer 10 automatically counts people moving, and edits and manages information generated accordingly. In addition, the software of the host computer 10 is a conventional 386 or higher computer, which is based on MS-WINDOW version 3.1 or higher, and is processed by receiving the situation generated from each sensor unit 30 through the control unit 20. It displays the status of each site so that it can be checked immediately, and has the function of editing and filing the status data so that it can be used in other tasks (related systems). In particular, since data generated from each sensor unit 30 can be transmitted through a general power line, unlike a conventional data communication concept, a data line is transmitted through a power line (using a general power plug) without using a separate communication cable. It has a function to process data. That is, data communication with a host computer is performed using a general power line, so construction is unnecessary without a separate communication facility. In addition, communication using RS-232C, which is used for communication between existing computers, may be selectively used.

On the other hand, the host software used in the apparatus is composed of communication software and business software. First, the communication software is briefly described. In the communication software, data is transmitted using a power line (power communication modem) for communication with a sensor. Communication is performed, and this is interface software that enables the basic software or business software running on the computer to smoothly start the data transmitted from the control unit to the power line.

Next, business software processes and edits the data transmitted through the power modem so that the user can check and check the actual situation, and edit and store the data so that it can be used in other business (existing system). Equipped with.

Here, the initialization processing of the system is a function of setting the communication mode and initializing the business system. The current status processing function of each gate displays and manages the current status of all gates in real time. In addition, the distribution status management for each gate is a function to display and manage the distribution status by time zone for all the gates in a graph, and the status specification management for each gate is managed to display and output the current status for each gate as a specification. Function. In addition, the work software has a situation management function for detecting and managing an operation state (normal operation situation detection management) for all sensors and a data management function for processing and editing other work data.

Meanwhile, the first control unit 20 performs a function of performing data communication with the host computer 10 by analyzing and grasping the situation transmitted from each sensor unit 30 for each type, processing the data into actual necessary data. Have.

FIG. 2A is a view schematically showing the overall configuration of the hardware of the automatic counting device according to the present invention. In FIG. 2A, the sensor unit 30 is installed at each gate through which a person enters and exits. Signal information about the number of people entering and leaving according to whether or not a person enters is generated and transmitted to the control unit 20. That is, the sensor unit has a function of transmitting a situation occurring in the field to the controller. Here, the concept of one set (maximum 1.5m correspondence) is used as a method to subdivide the actual phenomenon by type. Here, the concept of one set is the minimum hardware unit necessary for processing from a plurality of phenomena (virtual data) generated in a certain space to a single real phenomena (actual data). Therefore, one set has eight sensors (situation detection points) in length 1.2m, width 0.3m and height 0.05m, and independently transmits the phenomenon occurring from each sensor (minimum unit of situation detection). Playing a role. Each sensor (one set) operates independently of the control unit, and up to two sensors (two sets) can be simultaneously controlled by one control unit. The controller 20 receives the information signal transmitted from the sensor unit 30 from the communication unit, controls and edits the information signal, and transmits the same to the host computer 10. The host computer 10 analyzes and processes all the information and finally processes the information. The number of access customers according to the moving direction of the accessing customers is determined to provide the user with the information.

2B is a block diagram schematically illustrating the overall flow of the control unit 20. The control unit 20 includes a signal input unit 21 having a function of receiving a status signal from the sensor unit 30, A signal control unit 22 having a function of controlling a signal input from the sensor unit 30, a data processing and editing unit 23 for classifying the input signal for each situation and processing the data into necessary data; It includes a data communication unit for performing data bidirectional communication in accordance with the instructions of the host computer 10.

3 is a diagram showing the wiring of the apparatus according to the present invention, in which reference numerals 1 to 8 are basic sets, and each basic set includes two sensor units (1.0, 0.0; 1.0, 1, 0). 1, ------; 1. 7, 0, 7), and the sensor unit 30 is constituted by the plurality of basic sets 1 to 8 described above.

In addition, the control unit 20 is configured of a CPU that is applied to the H or L output signal output from the sensor unit 30 to control the entire device.

4 is a detailed circuit diagram of each sensor unit (1.0, 0.0-0 ----), and the operation of each sensor unit will be described in detail with reference to the following.

Each sensor unit (1.0, 0. 0 ----) detects the AC change voltage generated by the human body moving by the sensing operation of the pyroelectric infrared sensor for detecting the human body, and based on this, It checks the size and has a function of transmitting a signal to the controller 20 about whether or not a person enters.

First, when the human entry is detected by the pyroelectric infrared sensor IR1, the output signal is applied to one end of the OP amplifier U1A via the capacitor C2 and the resistor R3, and is 57 times AC first. The signal amplified and AC-amplified in this way is applied to one end of the OP amplifier U1B through the capacitor C5 and the resistor R9 and amplified by 53 times. Therefore, 57 × 53 = 3021 times amplification is finally achieved.

The signal amplified in this way is applied to one end of the comparator U2A and compared with a DC reference voltage of a predetermined magnitude set by the variable resistor VR1. As a result of the comparison by the comparator U2A, when the signal applied from the OP amplifier U1B is larger than the DC reference voltage, a high level signal is output from the comparator U2A, and the signal applied from the OP amplifier U1B is DC When the voltage is smaller than the reference voltage, a low level signal is output from the comparator U2A.

At this time, when the high level signal is output from the comparator U2A and applied to the base of the transistor Q1, the pnp transistor Q1 is turned off, so that the high level signal is output from the output terminal OUT. Accordingly, the signal of this high level operates the photocoupler of the control unit 20 so that the control unit 20 detects the entry of a person detected by one sensor unit (1.0,0.0, --------). You can judge.

On the other hand, when the low level signal is output from the comparator U2A and applied to the base of the pnp transistor Q1, the transistor Q1 is turned on, so that the low level signal is output from the output terminal OUT. Accordingly, the low level signal is applied to the photocoupler of the controller 20 so that the controller 20 can determine that no person has entered.

As described above, each sensor unit (1.0, 0.0, 1.0, 1.1, 0.1) is operated according to the same operation as described above, and the output signal corresponding thereto is shown in FIG. Is applied to corresponding inputs (1.0, 0.0, 1.0, 1.1, 0.1) of the control unit 20.

The control unit 20 determines the direction of entry of a person by the sequence of signals transmitted from each sensor unit (1.0, 0.0, 1.0, 1.1, -----).

That is, the control unit 20 is 0, 0 and 1.0, 0, 1 and 1. 1, 0, 2 and 1. 2, 0. 3 and 1. 3, 0. 4 and 1. 4, 0.5. And 1. 5, 0. 6 and 1. 6, 0. 7, and 1. 7, so the direction of travel is determined by the order of signal entry.

For example, in the case of a pair consisting of 0.0 and 1.0, when the signal from 0.0 enters the control unit 20 earlier than 1.0, the traveling direction is from 0.0 to 1.0. In addition, when the signal from 1.0 enters the control part 20 earlier than 0.0, the advancing direction shall advance from 1.0 to 0.0.

In this way, the advancing direction for each pair is determined.

Next, the situation generated in each is counted, and the counted data is classified and stored by ID, and the stored data is transferred to the main ON computer by the host computer using the power line.

FIG. 5 shows an overall flow chart for the processing of the software for the host, and FIGS. 6 to 12 show the processing flow in more detail. Hereinafter, the processing of the software for the host will be described with reference to FIGS. It explains in detail.

First, in step 1, the data is initialized to create a data file, and the process proceeds to step 2, and when the situation text is selected, the process proceeds to step 3 to process the accessor customer count in the form of text, and the communication connection. And communication environment, communication environment registration and communication line cutting. In step 4, the process proceeds to step 5 or step 9 depending on whether SETPORT is selected. If the SETPORT is selected, the process proceeds to the ConProc routine of step 5 to perform step 7 of determining whether to select the set through step 6, and then, in step 8, to repeat step 6 depending on whether to select close or not, to step 9 You will decide whether to proceed.

If the process proceeds to step 9, the process proceeds to step 13 depending on whether the connection / disconnection is selected. If the communication connection is proceeded to step 10, the process proceeds to the EDC_Close connection and the event of the communication path (Event Ignoring), closing the connection of the terminal device to close the communication device will not receive data from the electrical LAN, and proceeds to step 13. If the communication connection is not established in step 10, the process proceeds to the EDC_Open Connection routine to open the connected communication path and proceeds to the EDC_Setup Connectin routine to proceed to step 11.

Subsequently, in step 11, the information on the device to be accessed is set, the baud rate is set, the data size is set, the parity is set, the stop bit is set, the H / W FlowControl is set, and the S / W is set. By setting up FlowControl, you can register the data set in the device to be connected. Thereafter, if the registration is made without error in step 12, it is checked whether there is a character in the communication path, and after initializing the terminal device, the process proceeds to the next step, step 13, if the error is registered in step 12, the communication connection Close and proceed to step 13.

In step 13, when the port is connected, the process proceeds to step 14, where data is not received from the electric LAN, master is set, communication is established by receiving a response from the set master, and slave. The process then proceeds to step 15. In the case where the port is not connected in step 13, the process proceeds to step 15 immediately. In step 15, steps 16 and 17 are selected according to whether an event has occurred. If an event occurs, the process proceeds to step 16 to mask the data entered into the communication path, read the data from the communication path, search the read data, and display the data on the screen. If no event occurs, the process proceeds to step 17 immediately following. In the case of selecting Close in step 17, the process proceeds to step 18 in which it is determined whether to select the Situation-Image, and proceeds to step 4 in the case of not selecting Close. In step 18, it is asked whether or not to select the Situation Image. If the Situation Image is selected, the routine proceeds to the ImgProc routine. ImgProc routine is a routine that processes the accessor customer count in the form of Image, and handles communication connection, communication environment data registration, and communication line cutting. After this routine, in step 19, it is determined whether to select SETPORT, and if so, the procedure proceeds to the ConProc routine to perform step 20. In step 20, the device is set, the BaudRate is set, and the byte length is set. Thereafter, parity is set, StopBit is set, and FlowControl is set, and the process proceeds to step 21. If Set is set in step 21, the set data is registered and then the procedure goes to step 22. If Set is not selected, the procedure goes to step 22 immediately. In step 22, it is determined whether to select Close. If it is selected, the process proceeds directly to step 23, but otherwise, step 20 is repeated. In step 23, the selection of the connection / disconnection is determined. If no selection is made, the process proceeds directly to step 24;

In step 25, when the communication connection is established, the process proceeds to EDC_Close Connection, and step 26 is performed. In the case of disregarding the occurrence of an event of the communication path in step 26, the connection of the terminal device is closed and the communication device is closed so that data from the electric LAN is not received, and then the process proceeds to step 24. If no communication connection is made in step 25, the process proceeds to the EDC_Open Connection to open the connected communication path. After that, the process proceeds to the EDC_Open Connection routine to perform step 27. In step 27, the information on the device to be connected is obtained to set the BaudRate, the data size is set, and then the parity is set. After setting StopBit, H / W FlowControl is set and S / W FlowControl is set. After registering the data set in the device to be connected, the process proceeds to step 28. If the registration is made without error in step 28, it is checked whether a character has entered the communication path, and after the terminal device is initialized, the process proceeds to step 24. If there is an error, the process proceeds to step 24 after closing the communication connection. In step 24, it is determined whether the port is connected, and in case of connection, step 29 is performed. In step 29, the master is set up without receiving data from the electric LAN. After receiving the response from the set master, the slave is set up to start communication, and then the process proceeds to step 28. If the port is not connected in step 24, the process proceeds to step 30 to determine the occurrence of an event. If an event occurs, step 31 is performed. First, mask the data entered into the communication path, read the data from the communication path, search for the read data, and then display the data on the screen. Proceed to 32. If no event occurs in step 30, the flow proceeds directly to step 30 to determine whether to select Close. If Close is not selected in Step 32, the process returns to Step 19 to perform the next step. After selecting Close, in Step 33, it is determined whether Analysis is selected. If not, it proceeds to Step 34. If it is selected, AnaProc analyzes the data received by the sensor and displays the data in the form of bar graph and line graph. Proceed. After this routine, in step 35, a date is inputted, and a year, month, day, gate, and graph shape are selected, and then the process proceeds to step 36. In step 36, it is determined whether or not to print the selected data in list format or step 37 in accordance with whether or not listPrint is selected. In step 37, it is determined whether or not to select GraphPrint. The process then proceeds to step 38, otherwise it proceeds directly to step 38. Thereafter, in step 38, it is determined whether to select Close, and if it is selected, the process proceeds directly to step 34, in which case, step 35 is performed again. In step 34, it is determined whether to select About. If the selection is made, the procedure proceeds to step 39 after showing the help screen with the AboutProc routine indicating the help screen. In addition, if About is not selected in step 34, the process proceeds directly to step 39, where it is determined whether an exit routine for completing all operations is selected. If the exit routine is not selected in step 39, the process returns to step 2 and the next step is performed.

First, in step 101, the ID setter is set, the timer is set to 50 msec, and then BaodRate is set to 2400 bps. In step 102, if it is determined that Rx data has been entered, the flow proceeds directly to the next step 103. If data is entered, the flow proceeds to step 104. If the data is the same, it is determined whether RXDATA is the same as IDData, and if it is the same, step 105 is performed. If not, the process proceeds to step 103 where data is read by the sensor. In step 106, it is determined whether the sensor is set to 0.0. If it is set, the process proceeds to step 107; otherwise, the process proceeds to step 109. If the process proceeds to step 107, it is determined whether Dir_in is set to 0. If it is set to 0, the process proceeds to step 115. Otherwise, the process proceeds to step 108, and if it is set to determine whether the Dir_out is set to 10, the process proceeds to step 108. In step 115, if it is not set, Dir_in is set to 00, TM00_ON is cleared, and TM00_DLY is cleared. In step 106, if the sensor is not set to 0.0, the process proceeds to step 109 to determine whether Dir_in is set to 00. If not, the process proceeds to step 115. If Dir_in is set to 00, Proceeds to step 110 after setting TM00_ON. In step 110, it is determined whether the sensor is set to 10. If the sensor is not set to 10, the process proceeds to step 112, and if the sensor is set to 10, the process proceeds to step 111. FIG. If Dir_in is set to 10 in step 111, the process proceeds to step 115. If Dir_in is not set to 10, the process proceeds to step 115 after setting Dir_in to 10. If the sensor is not set to 10 in step 110, the process proceeds to step 115. In step 111, it is determined whether Dir_in is set to 10. If it is set to 10, the process proceeds directly to step 115. If it is not set to 10, step 115 is performed after setting Dir_in to 10.

In step 113, it is determined whether TM00_DLY is set. If set, step 114 is performed. If not, step 115 is performed. In step 115, it is determined whether the sensor is set to 1.0, and if not, the process proceeds to step 120; In step 116, it is determined whether Dir_out is set to 10. If it is set to 10, the process proceeds to step 126; otherwise, the process proceeds to step 117. In step 117, it is determined whether Dir_in is set to 00, and if it is set, the process proceeds to step 126. Otherwise, the process proceeds to step 118 and then to step 126. If the sensor is not set to 1.0 in step 115, the process proceeds to step 120 to determine whether Dir_out is set to 10. If not set to 10, the process proceeds to step 126. If Dir_out is set to 10, After setting TM10_ON, the process proceeds to step 121. In step 121, it is determined whether the sensor is set to 00. If not, the process proceeds to step 123. If not, the process proceeds to step 122, and it is determined whether Dir_out is set to 00. If Dir_out is set to 00 in step 122, the process proceeds to step 126. If it is not set to 00, the process proceeds to step 126 after setting Dir _- out to 00. If the sensor is not set to 00 in step 121, the process proceeds to step 123 to determine whether Dir_out is set to 00. At this time, if Dir_out is set to 00, Outcnt is set to 0 and then proceeds to step 126 via Step 124. If Dir_out is not set to 00, the procedure proceeds to Step 125 to determine whether TM10_DLY is set. If TM10_DLY is set, the process proceeds to step 126 through step 124. If TM10_DLY is not set, the process proceeds directly to step 126. Subsequently, in step 126, it is determined whether all the number of input data is set, and if it is set, it adds 1 to the input data and clears In_cnt, and then proceeds to step 127, but all the numbers of data input in step 126 are not set. If only In_cnt is cleared, the process proceeds to step 127. In step 127, it is determined whether In_cnt is set to 0, and if not set, the process proceeds to step 131. If In_cnt is set to 0, the process proceeds to Step 128 after adding 1 to In_cnt_buf. In step 128, it is determined whether Dir_in is set to 1, and if it is set to 1, the process proceeds to step 129 after setting Dup1_in to 1, and immediately proceeds to step 129 when Dir_in is not set to 1. Thereafter, in step 129, it is determined whether in_cnt is set to 1, and if it is set to 1, the flow proceeds to step 130 to determine whether all data is set. If all data is not set in step 130, the process proceeds directly to step 131. If all data is set, the process proceeds to step 131 after adding 1 to in_cnt_buf. In step 131, it is determined whether all the number of out data is set. If it is set, 1 is added to the out data, and then out_cnt is cleared. The process then proceeds to step 132. In step 132, it is determined whether out_cnt is set to 0. If not, the process proceeds to step 136. If out_cnt is set to 0, the process proceeds to step 133 after adding 1 to out_cnt_buf.
